Notation analysis has now gained wide use in the assessment of competitive football play. Computer-aided methods have largely replaced the use of hand-notation systems. Whilst a hand-notation approach has been adopted previously in assessing injury-risk in football, the recording and analysing of events with injury potential are time-consuming. In this report, a computerised system of notating incidents in the game is described. Key incidents are monitored with respect to degree of injury potential, location and other factors. The use of the system is illustrated by comparing home and away performances in Premier League matches between Manchester United and Liverpool F.C. The system has advantages in speed and accuracy of handling data related to injury and injury risk. © 2002 Elsevier Science Ltd. All rights reserved.

Introduction: Firefighting is a high-risk job with a high prevalence of work-related musculoskeletal disorders (WMSDs). The aim of his study was to determine the prevalence of WMSDs, estimate the likelihood of subsequent disorders, and investigate the effect of NASM-based training protocol on firefighters function. Method: First, prevalence and region of WMSDs in all 524 male Isfahan firefighters were determined by Medical-history-questionnaire. Then, functional movement screen (FMS) separated firefighters to the 2-dimension FMS score (FMSCS≤14 or FMSCS>14) to show at risk firefighters. Finally, 40 Participants with both FMSCS≤14 and common WMSDs randomly assigned to either an intervention (IG) (n = 20) or control (CG) (n = 20) group. The IG received NASM-based training, while the CG engaged in daily activities. Outcomes included movement efficiency during landing error scoring system-real time, Y balance, single-leg squat, and deep squat, which were assessed in pretest and posttest. Results: The prevalence of disorders was 52.1%, which lower limb, back, upper limb, and neck were the highest prevalence respectively. Only lower limb and back disorders could identify individuals at disorder risk with a likelihood of 89% and 71%, sequentially. Also, movement performance significantly improved in all functional tests in IG relative to CG. Conclusions: Considering high disorder rate in firefighters, the value of our study lies in alleging a systematic model periodically to reduce WMSDs and risk of subsequent disorders. Not only our model determined the prevalence of WMSDs, but it also identified those who are at risk. In addition, our model represents exercise therapy as a solution. © 2023 Elsevier Ltd

Six young obese females (20.5±1.22 years; BMI=34.5±4.3 kg/m2) participated in a resistance exercise (RE) protocol (12 exercises, 4 sets × 15 repetitions at 60% of 1RM), an aerobic exercise (AE) protocol (3 sets × 10 min ergometer cycling at 60% of maximal heart rate with 5 min of rest between sets), and a control session. Blood samples were collected before, and immediately after and 10 h after exercise. All protocols were done in follicular phase of the menstrual cycle. ANOVA (3×3) with repeated measure on exercise (3 levels) and time (3 levels) factors was used to determine the effects of exercise protocol, time and exercise protocol by blood sampling time interaction, triglycerides, HDL-cholesterol, LDL-cholesterol, and glucose concentrations. Immediately and 10 h after AE, serum leptin was significantly lower (p <0.05). Serum insulin after AE was lower than after RE and control sessions (p <0.05). Furthermore, no significant differences were found in serum leptin and insulin between RE and control sessions immediately after and 10 h after exercise. Blood glucose, triglycerides, total cholesterol, HDL-cholesterol and LDL-cholesterol were unchanged in both exercise protocols. In conclusion, AE resulted in a serum leptin reduction and suppressed the circadian rhythm of serum insulin when sampled immediately and 10 h after exercise; instread, RE did not result in serum leptin or insulin changes. © Springer-Verlag Italia 2008.

A lateral positioned patella has long been regarded as a major contributing factor in the development of patella femoral pain (PFP). Despite extensive research, there is still little consensus as to the most effective treatment strategy for the management of patients with lateral patellar displacement (LPD). Computational intelligence methods are proving useful aids to physicians and other medical staff, improving objectivity when making diagnostic and treatment decisions and reducing the time to make decisions. This study describes an adaptive network-based fuzzy inference system (ANFIS) used to build a model for the indirect prediction of rehabilitation treatment outcomes for females with LPD from only demographic and clinical characteristics. The prediction abilities offered using two ANFIS models are presented using data from 48 female patients referred to rehabilitation clinics of Isfahan Ayatollah Kashani and Al Zahra hospitals, Iran. The results indicate that the ANFIS model has strong potential to improve indirect prediction of rehabilitation treatment for females with LPD with a high degree of accuracy and robustness. © 2017

This study investigated bilateral and unilateral asymmetries of strength and flexibility in male young professional soccer players. Thirty-six soccer players (age: 18.9 ± 1.4 years) participated in this study. A Biodex Isokinetic Dynamometer was used to assess the hamstring and quadriceps strength at selected speeds of 60°/s, 180°/s and 300°/s. Hip joint flexibility was measured using a goniometer. No difference was observed in conventional strength ratio, dynamic control ratio and fast/slow speed ratio between the dominant and non-dominant legs (p>0.05). All but one of the players (97.2%) had musculoskeletal abnormality (bilateral imbalance > 10%) in one or more specific muscle groups. The dominant leg had greater hip joint flexibility compared with the non-dominant leg (108.8 ± 10.7° versus 104.6 ± 9.8°, respectively). The findings support the hypothesis that physical performance and movement pattern experienced during soccer playing may negatively change the balance of strength in both legs (bilateral strength balance), but not on the same leg of the young male professional soccer players. The results can be helpful for trainers and coaches to decide whether the players need to improve their balance and strength which in turn may prevent injury. It is suggested that in professional soccer training, quadriceps and hamstrings muscle strength, as well as hip joint flexibility should not be overlooked. © Editorial Committee of Journal of Human Kinetics.

Background: Bilateral symmetry evaluation in lower limb is used for injury prevention, and is an indicator of returning to post-injury activity. The aim of present study was to investigate the effect of different angular velocities on asymmetry of the hamstring-to-quadriceps strength ratio. Method: Isokinetic concentric hamstring to quadriceps (H:Q) peak torque ratio of the 27 male and female professional basketball players was measured at seven angular velocities (60, 90, 120, 150, 180, 180, 240, 300 deg s−1) on both dominant and non-dominant legs with Biodex Isokinetic Dynamometer. Repeated measure analysis of variance was used to assess the effects of angular velocity and limb side on our outcomes (p ≤ 0.05). Results: The results showed that with increasing angular velocity, the ratio of hamstrings to quadriceps increases (p = 0.001). There was no difference between dominant and non-dominant limbs in the H:Q peak torque ratio (p = 0.254). In addition, velocity of measurement did not affect the bilateral asymmetry of peak torque ratio of the H:Q of both sides (p = 0.852). Conclusions: Based on the results of this study, it can be concluded that measurement velocity does not affect the bilateral asymmetry of the H:Q peak torque ratio of the dominant and non-dominant limbs. In clinical assessments of H:Q bilateral asymmetry, we suggest that physical trainer can assess bilateral asymmetry of H:Q with arbitrary angular velocities. © 2022 Elsevier B.V.

Background and Objective: IGFs (Insulin-like growth factors) and some binding proteins can cause occurrence and recurrence of breast cancer. Since the role of combined exercise training on these factors is not clear, therefore, the aim of this study was to look at the changes of IGF axis and some binding proteins in postmenopausal women with breast cancer after 15 weeks of combined exercise training. Materials and Methods: Twenty- nine women with breast cancer (58.27 ± 6.31 years) who underwent surgery, chemotherapy and radiation- therapy with current hormone therapy were divided into two groups of experimental and control. Subjects of the experimental group performed 15 weeks of combined exercises including walking (2 sessions per week) and resistance training (2 sessions per week that differed from walking days). Data were analyzed by using ANCOVA (p< 0.05). Results: Combined exercise training had significant effect on IGF-1 levels (P= 0.001), IGFB-3 levels (P= 0.000) and IGF-1: IGFB-3 (P= 0.000) in postmenopausal women with breast cancer. After 15 weeks, IGE -1 reduced in the experimental group up to 9 percent and IGFB-3 increased by 28 percent. On the other hand, exercise training had no significant effect on the IGFB-1 (P= 0.652) in postmenopausal women with breast cancer. Conclusion: While the IGF axis factors and some binding proteins play an important role in breast cancer and its recurrence, it seems that changes in these factors through combined exercise training programs can delay its recurrence.

Sensorimotor function is impaired in chronic ankle instability (CAI) patients. CAI patients have an increased sensitivity to fatigue relative to controls. Few investigations have quantified functional movement scores in CAI patients or the effect of fatigue on such scores. Therefore, we characterized functional movement scores before and after fatigue in 40 collegiate athletes with CAI. Three movement patterns (double-limb squat, double-limb squat with heel lift, and single-limb squat) were completed before and after fatigue and scored using Fusionetics®. All Fusionetics scores were higher (worse) after fatigue. The results demonstrate that functional movement scores were sensitive to fatigue. © 2018 Human Kinetics, Inc.

Background: Impairment of postural adjustments in elderly is associated with decreased functional mobility, balance confidence and quality of life. Aims: We studied the effects of anticipatory postural adjustments focused training on postural preparation, balance confidence and quality of life of the elderly. Methods: It was a single-blind randomized controlled trial. The sample included 60 males with history of falling (at least once in the past 6 months). They were matched and randomly assigned into three groups: perturbation, balance, and no training. The electrical activity of the muscles was measured by electromyography. The Activities-specific Balance Confidence (ABC) scale and the SF-36 questionnaire were used to assess balance confidence and quality of life, respectively. Repeated-measures ANOVA was used for data analysis (significant level 0.05). Results: The type of training had significant interaction effect on muscle latency (F(2, 46) ≥ 71.06, P ≤ 0.001, η2 ≥ 0.75). Compared to the other two groups, perturbation training group showed significantly more improvement in ABC scale (F(2, 46) = 14.94, P ≤ 0.000, η2 ≥ 0.39). It also significantly showed more improvement than no training group in all areas of SF-36 questionnaire, except for mental health (F(2, 46) ≥ 6.56, P ≤ 0.03, η2 ≥ 0.22). Conclusions: Our findings support the use of perturbation training, as it reduced the probability of falling (by decreasing muscle latency and increasing posture preparation), improved the balance confidence for daily activities, and improved the quality of life. © 2019, Springer Nature Switzerland AG.

Purpose: Balance is an important performance aspect of all athletes. The aim of this study was to compare static and dynamic balance in soccer players in different positions. Methods: Forty youth and young adult professional soccer players were divided into four groups according to their playing positions: goalkeepers (GK), defenders (DF), midfielders (MF) and forwards (FW) (10 per position). Static and dynamic balance assessed on the dominant and non-dominant legs were measured using a force platform for 30s (static one-leg stand), and “Y Balance Test” (dynamic balance). Results: GK exhibited greater ML static balance (less ML sway) compared with other players (p < 0.02–0.001). Moreover, results demonstrated better GK dynamic balance compared to DF and FW (p < 0.04–0.006). MF showed better dynamic balance than DF and FW (p < 0.019–0.007) and lower dynamic balance scores were found among DF and FW (p < 0.05). Conclusion: In conclusion, these results affirm position-specific balance performance with greater static and dynamic balance of GK and dynamic balance with MF. It is suggested that evaluation of balance and postural control performance should be considered a relevant part of the position-specific functional evaluation of soccer players. © 2023 Elsevier Ltd

Background: The process of recovery plays a significant role in sustaining athletic performance and preventing exhaustion among players. Active recovery (AR) is generally accepted as a series of light intrinsic activity after intense activities. It is believed that this type of recovery improves athletes’ recovery process. On the other hand, among different recovery methods, recovery in water in different temperatures is highly reputed among athletes. Aims and Objectives: The present research was aimed at comparison of effects of AR and deep water running (DWR) on serum levels of creatine kinase (CK), lactate dehydrogenase (LDH), and aspartate aminotransferases (AST) as indices of muscular damage subsequent to a simulated soccer game among 19-21-year-old players of Ahwaz Naft soccer team present in premier league. Materials and Methods: 18 players of Naft soccer team were randomly assigned to either of the two 9 membered groups of AR and DWR. Afterward, the aforementioned participants took part in a 90 min (including two 45 min rounds of random activity) simulated soccer activity that was primarily designed by Bangsbow and modified by Bishop et al. After the activity, one group was administered an AR while the other was administered DWR recovery. To compare the changes of variables in the aforementioned groups, the statistical method of mixed variance analysis among individuals was used. Results: The difference between changes of variables between the groups of AR and DWR was not statistically significant (P = 0.541, P = 115 and P = 748, respectively, for LDH, CK, and AST). Conclusion: It seems that there is no statistically significant difference between the effects of AR and DWR recovery on muscular damages of soccer players after a period of playing. However, still more research is required in this regard. © 2018 Mohammad Sajadian, et al.

Background: Triathlon is a popular sport match that combines swimming, cycling, and running into a single event. During each stage, athletes have specific positions which may affect their spinal curvatures. The aim of this study was to compare forward head posture, thoracic kyphosis, and lumbar lordosis in triathlon athletes and non-athletes. Methods: This study included 40 Iranian male triathlon athletes and 40 non-athletes. Each athlete had to complete a questionnaire about training procedures and his experience of participation in a triathlon. The degrees of forward head, kyphosis, and lordosis were measured using a goniometer and a flexible ruler. Findings: The mean degree of forward head in triathlon athletes (44.58° ± 7.11°) was significantly (about 20%) greater than non-athletes (28.55° ± 7.24°). A significant difference was observed in mean kyphosis between triathlon athletes and non-athletes (45.86° ± 6.68° vs. 43.03° ± 5.6°). However, no significant difference was found between triathlon athletes and non-athletes in mean lordosis (32.96° ± 5.85° vs. 33.76° ± 4.16°). Conclusion: It can be concluded that posing specific postures during the 3 stages of a triathlon increases forward head posture and kyphosis among athletes. Therefore, stretching and strengthening exercises are recommended to prevent athletes from developing these abnormalities.

Objectives: Knee osteoarthritis is one of the most common musculoskeletal problems in older adults. Pain, stiffness, tenderness, decreased muscle strength and joint range of motion, impaired proprioception, and balance problems lead to impaired physical function, making the person incapable of performing functional activities. Therefore, it is necessary to use strategies to control and reduce the complications of the disease and improve their daily functional activities. The aim of this study was to compare the effect of land exercise therapy and hydrotherapy on functional activities in older women with knee osteoarthritis. Methods & Materials: Fifty-four female patients with knee osteoarthritis within an age range of 60-69 years (height: 159.96 ±5.53, weight: 76.93±9.50) were selected as available, and were randomly divided into two groups of land exercise therapy and hydrotherapy for 8 weeks. To evaluate the patients' functional activities, timed up & go, 30-second chair stand, 40-meter fast paced walk test, stair climb test, and 6-minute walk test were used. SPSS V. 26 and analysis of variance for repeated measures were used for data analysis. Results: The results showed that The results showed that both land exercise therapy and hydrotherapy methods caused intra-group changes in functional tests (P ≤ 0.05) but the difference between the two groups was not significant (P ≥ 0.05), which indicates the same effect of the methods used in the study. Conclusion: Land exercise therapy has had the same effect as hydrotherapy on timed get up & go, 30-second chair stand, 40-meter fast paced walk test, stair climb test, and 6-minute walk test, which means that it has shown effective for the patients’ functional activities. Any of these methods can thus be recommended according to the conditions of each patient. © 2022. Iranian Journal of Ageing.All Rights Reserved

Introduction: Parkinson's disease (PD) is a chronic, progressive disorder that mainly affects the central nervous system and, consequently, the patient's functional status. This study aimed to compare the effect of 8-week rebound therapy-based exercise program and weight-supported exercises on the range of motion, proprioception, and the quality of life in patients with PD. Methods: Twenty patients were randomly divided into two equal groups of weight-bearing exercises and rebound exercise with no significant differences in age, weight, and height. The variables of the range of motion, proprioception, and the quality of life were assessed in pre- and posttest. Data were analyzed using repeated measure ANOVA and t-test at a significant level of P < 0.05. Results: All of the variables in the two groups were significantly improved after 8 weeks of exercise, whereas the improvement rate in the rebound therapy group was more than the weight-bearing exercises group in range of motion (134.60 ± 13.22 vs. 118.38 ± 12.48), proprioception (7.60 ± 3.22 vs. 10.38 ± 2.48), and the quality of life (147.60 ± 13.22 vs. 118.38 ± 12.48) of the patients (P < 0.001 for all variables). Conclusions: Given that both rebound and weight-supported exercises are effective on improving the range of motion, proprioception, and the quality of life of people with PD, it is recommended that the benefits of these exercises to be used in physical rehabilitation programs. However, rebound therapy exercises have had a greater effect on people with PD, and it seems better to use these exercises more than others. © 2019 International Journal of Preventive Medicine.

Background and Objective: Decreasing muscle strength and the quality of life (QOL) are some major problems for hemophilic patients. The purpose of this study was to compare two treatment protocols, including land-based and water-based exercise therapy on muscle strength and QOL in patients with hemophilia for 8 weeks. Methods: In this experimental study, thirty-eight patients with hemophilia (type A) were randomly assigned into land-based exercise therapy, hydrotherapy and control groups. The participants in hydrotherapy group performed hamstring stretching and quadriceps strengthening exercises in water while the patients in land-based exercise therapy group followed the same exercises outside the water three days in a week for 8 weeks and the subjects in control group have their everyday life. The muscle strength and QOL were evaluated using hand held dynamometer and WOMAC questionnaire at base line and after interventions, respectively. Findings: The patients who completed the interventions had significant increase in hamstring (Mean±SD: hydrotherapy: post-test 17.7±4.8; exercise therapy: post-test 17.3±8.1; control: post-test 12.3±6.6) strength and quadriceps (Mean±SD: hydrotherapy: post-test 20.9±5.5; exercise therapy: post-test20.2±7.7; control: post-test (15.2±6.8) and improvement in QOL compared to subjects in control group (p<0.001). More significant (p<0.01) improvement in QOL (hydrotherapy: post-test 26.4±9.1; exercise therapy: post-test 26.4±9.1; control: post-test 43.4±6.4) was found in participants of WET group in comparison to those in LET group, although no significant (p>0.05) difference was detected between the WET and LET therapeutic programs in changes of quadriceps and hamstring muscle strength at baseline and after finishing the treatment protocols. Conclusion: Both interventions can improve quality of life and muscle strength of knee joint in patients with knee joint arthropathy due to hemophilia, although the influence of water-based exercise therapy program in improving QOL protocol is more than land-based exercise therapy method.

Objective:To investigate the effect of corrective exercises on functional movement patterns, sensorimotor function, self-reported function, and fatigue sensitivity in collegiate athletes with chronic ankle instability (CAI).Design:A randomized controlled trial.Setting:Laboratory of sports sciences.Participants:Forty male volunteers were randomly assigned to the experimental group (age 21.2 ± 1.7 years, height 174.5 ± 6.1 cm, and weight 69.6 ± 6.9 kg) or the control group (age 20.9 ± 1.8 years, height 178.2 ± 6.6 cm, and weight 68.8 ± 8.1 kg).Intervention:Participants in the experimental group performed supervised corrective exercises 3 times per week for 8 weeks. Fatigue was induced with a progressive treadmill protocol before and after the 8-week intervention.Main Outcome Measures:Outcomes included movement efficiency during 3 squat tasks, static and dynamic postural control, strength of the ankle musculature, joint position sense, and self-reported function with the Foot and Ankle Ability Measure subscales. These outcomes were assessed before and immediately after fatiguing treadmill running both before and after 8-weeks of corrective exercises.Results:Significant improvements in movement efficiency, sensorimotor function, and self-reported function were noted in the experimental group relative to the control group (P < 0.001), in a nonfatigued state. However, in a fatigued stated, the experimental intervention only improved static postural control (P = 0.016) relative to the control group.Conclusions:These findings demonstrate that 8-weeks of corrective exercises were effective at enhancing movement efficiency, sensorimotor function, and self-reported function in collegiate athletes with CAI. However, this intervention program has limited abilities at reducing the effects of fatigue. © 2019 Wolters Kluwer Health, Inc. All rights reserved.

The barbell trajectory of snatch weightlifting has been investigated by several researchers. They suggested three optimal trajectory patterns (type A, B and C). But, there is no agreement for introducing the best overall trajectory. One probable reason would be this idea that the selected criterion used by the previous researchers might not be appropriate. Therefore we used a mathematical approach to judge between the conflicts. We made a multi-segments biomechanical model to evaluate the snatch motions while considering the selected mechanical cost. This method is an appropriate tool for coaches to examine several trajectories for making a good decision.

Aim. Physical activity inversely associated with inflammatory markers. Active old people as compared with non-active have the lower level of IL-6, TNF-α and CRP. The purpose of this study was to determine the effect of 12 weeks of aerobic exercises on inflammatory markers in elderly women (75-60 old years). Methods. Twenty old women were chosen and then randomly were divided into two groups; control (mean±SD, age 68 ± 4 years, height 1/55±0/4 m, weight 72/67 ± 14/62 kg) and experimental (age 69 ± 3 years, height 1.56±0/5 m, body weight 68/36 ± 15/90 kg). Weight, body fat percent and waist to hip ratio were assessed by the body composition analyzer. The inflammatory markers IL - 6, TNF-α and CRP were measured before and after aerobic exercise program (walking three sessions per week, for 3 months) by ELIZA. Paired t-test and analysis of covariance was used to analyze the data. Results. Significant reduction was observed in body weight (68 vs. 64 kg), fat percent (38 vs. 35%), body mass index (28 vs. 26) and waist to hip ratio (1/02 vs. 1/01) in experimental group after the training period (P<0.05). But no significant difference was found for control group in these variables (P>0.05). Following training modality TNF-α and CRP levels decreased significantly (P<0.05), but no change was observed in IL-6 (P>0.05). No significant changes were found for the control group in inflammation markers (P>0.05). It can be concluded that aerobic training would be recommended as an appropriate modality for the elderly women for improving their health and reducing cardiovascular risk factors.

Background: To resolve the impairments associated with spinal cord injury (SCI), such as decreased balance, patients have been recommended to undergo various therapeutic strategies, including the use of different physical exercise methods. The aim of this study was to evaluate the efficiency of using rebound therapy (exercise on a trampoline) on SCI individuals' static stability. Methods: Sixteen people with SCI (American Spinal Cord Association classification: A = 6, B = 6, C = 2, and D = 2) were randomly assigned to an experimental (rebound exercise) group or a control group. The rebound therapy exercise program, lasting 12 weeks, was performed by means of a modified trampoline. During the said period, the experimental group received rebound therapy exercise for 10 to 30 minutes 3 sessions a week. Standing stability parameters (ie, excursion, velocity, and path length of the center of pressure in mediolateral and anteroposterior plane) were assessed before and after the exercise intervention by Kistler force plate (50 × 60 cm). Data were analyzed by repeated measures analysis of variance. Results: Significant interactions were observed for all 6 dependent variables except excursion of the center of pressure in mediolateral and the path length of center of pressure in anteroposterior plane (P < .01). This means that the control group had no progress, whereas the experimental group made a significant improvement in terms of static stability. Conclusion: The results of this study confirmed that rebound therapy could reinforce the static stability of individuals with SCI during motionless standing. It suggests that rebound exercise is a useful sports rehabilitation method for patients with SCI and other wheelchair-bound individuals. © 2019 Human Kinetics, Inc.

Background: Spinal cord injury (SCI) often results in reduced core region function and shoulder pain among wheelchair users. This study aimed to investigate the effectiveness of modified dynamic neuromuscular stabilization (DNS) exercises on core region function and shoulder pain in patients with incomplete paraplegic SCI. Methods: In this semi-experimental study, ten male patients with SCI were purposefully selected based on inclusion criteria and participated as an experimental group. Core region function and shoulder pain were measured before intervention using the modified plank test, an abdominal pressure cuff device, and the Wheelchair Users' Shoulder Pain Index (WUSPI) questionnaire. Participants first completed an eight-week non-exercise period, followed by an intermediate assessment. They then engaged in eight weeks of modified DNS exercises, after which measurements were repeated. Data were analyzed using SPSS version 26, with repeated measures ANOVA applied (P≤0.05). Results: Significant improvements were observed in core function, transverse abdominal muscle strength, and shoulder pain (measured by WUSPI scores) after the exercise period compared to the non-exercise phase. These improvements were statistically significant (P≤0.05). Conclusion: The findings suggest that modified DNS exercises can be an effective and low-cost addition to the physical rehabilitation of patients with incomplete paraplegic SCI. © 2025 Shiraz University of Medical Sciences.

Background The aim of this study was to investigate the effect of 8 weeks regular corrective exercise on spinal columns deformities, such as kyphosis, scoliosis and lumbar lordosis, in girl students. Methods: 150 girl students in Jiroft city, aged 12-14 year, participated in this study. The subjects were examined twice in beginning and after 8 weeks of corrective exercise. Spinal column deformities were measured by grid plane, plumb line and other relevant testes. Co-variation test was used to analysis the data. Findings: In 12 year-old subjets the degree of kyphosis and scoliosis in post-test were lower than pre-test and differences were significant (F = 28.5, P < 0.001 and F = 100, P < 0.001, respectively), but in lordosis deformity differences were not significant (F = 3.32, P ≥ 0.05). The differences between pre and post measurents of kyphosis and scoliosis in 13 year-old subjects were significant (F = 39.7, P < 0.001, F= 47.8 and P < 0.001, respectively) but in lordosis deformity differences were not significant (P ≥ 0.05, F = 3.34). Finally in 14 year-old subjects for kyphosis, scoliosis and lumbar lordosis, differences between pre and post measurents were significant (F = 7.9, P < 0.001, F = 112.4, P < 0.001, and F = 16.6, P = 0.009, respectively). Conclusion:: It seems that corrective exercise is the safe and valuable method to correct spinal deformities such as kyphosis, scoliosis, and lumbar lordosis and it can decrease the old age problems and disabilities. © 2018, Isfahan University of Medical Sciences(IUMS).

Introduction: Patellfemoral pain syndrome is one of the most common knee joint problems that affect athletes and non-athletes. Knee brace is often used as a treatment method for patellar realignment. The aim of the present study was to determine the effects of a patella support brace on myoelectric activity of selected knee muscles during single leg landing in healthy females. Materials and Methods: 19 healthy female students (Mean age: 23.6±1.98 years, height: 163.5±5.88 cm, weight: 62.3±3.6 kg) participated in this study. Myoelectric activity of biceps femoris, semitendinosus, vastus medialis and vastus lateralis were collected during single leg landing in with and without using the patella support brace conditions. Results: Use of the patella support brace had no significant effect on myoelectric activity for the semitendinosus (p=0.668), vastus medialis (VM) (p=0.915) and vastus lateralis (VL) (P=0.134), while myoelectric activity for biceps femoris (p=0.005) and ratio of VM/VL myoelectric activity significantly increased (p=0.045). Conclusion: Our results revealed that biceps femoris activity and vastus medialis/vastus lateralis ratio increased after using patella support brace during single leg landing. Further studies on kinematic and kinetic variables are needed to describe these changes in muscular activity when using the patella support brace.
