Abstract

The aim of this study was to determine the effect of 12 weeks of "Tai Chi"
exercise on some of physiological and psychological factors in elderly living in
Nursing Home. In this experimental study, 58 elderly male and female age
69.15±5.3 yr, height 154 ± 0.1 cm and weight 58.13 ±4.4 kg, lived in Sadeghie
Nursing Home were selected and objectively divided in experimental (n=27) and
control groups (n=30). The experimental group trained for 3 month, three
session per/week, and 30 minute in each session. Heart rate, blood pressure,
hands grip strength, flexibility, Berg balance scale, depression and quality of
sleep were measured before and after the exercise program. Data were
analyzed for group differences using covariance test. There was no significant
group difference in heart rate, blood pressure and flexibility. Hands grip
strength, quality of sleep and balance scales were significantly improved and
depression significantly decreased in experimental compared with control
group. So, it seems that using Tai Chi exercise can improve some of
physiological factors, depression and quality of sleep in elderly

Abstract

Functional Movement Screen Test is one of the tests used to identify asymmetries and limitations in basic and fundamental movements. For time management and fast execution of this test, some researchers have suggested reducing the number of tests. The purpose of the present study was to investigate the internal consistency and correlation between components of this test. The present study was a correlational study. In this study, movement screen test was performed on 165 male and female students aged 18 to 25 years of Shahid Beheshti University using a special FMS kit. Results: The internal consistency of the test, measured by Cronbach's alpha method, was acceptable (α=0.71). The results of multivariate regression test showed that there was a low to medium correlation between the internal components of the test, but a high correlation was observed between the test components and the final FMS score. The results also showed a high correlation between the "four small movements" (Active leg raising, shoulder mobility, stability push up and rotary stability) and the total FMS score and a low correlation between the "three big movements" and the FMS score. Motor function screen test is a valid tool for evaluating motor performance. The results also show that in large communities such as students, and if there is a time limit, "four small movements" can be used instead of seven.

Abstract

The prevalence of sports injuries in martial arts is high. Most Taekwondo injuries also occur in the lower extremities. The aim of this study is to compare the effect of a period of plyometric exercises, with and without stretching exercises, on knee valgus dynamics, flexibility and functional variables of elite female taekwondo athletes at risk of anterior cruciate ligament injuries.  45 elite female taekwondo athletes aged 15-25 years with anterior cruciate ligament injuries participated in this study. Knee valgus dynamics in squat movement were measured with KINOVEA software. Flexibility was measured with direct leg lift test and performance indicators were measured with Y-balance, three-step jump and error scoring system. The tests were conducted before and after eight weeks of plyometric exercises, along with the stretching exercises. Then, the data obtained were analyzed.There was a significant difference between the results of pre-test and post-test data measured in the two experimental groups (P ≥ 0.05). According to the stark differences based on the analyzed data, it is clearly evident that the group of athletes with plyometric exercises with stretching have obtained far superior results and outcome..Plyometric exercises with stretching had a significant effect on reducing the risk of injury, as well as increasing the flexibility and performance of elite female taekwondo athletes exposed to anterior cruciate ligament injury. Considering the vast improvements reported for the plyometric training group with stretching, it is recommended that these interventions be used to reduce the risk of injury and increase the performance of taekwondo practitioners.

Abstract

Background and aim: The purpose of this study is to examine how eight weeks of general exercises (GEs) combined with cognitive functional therapy (CFT) affect women with chronic non-specific low back pain (CNSLBP) in terms of pain, quality of life (QoL), and muscle endurance.
Methods: 45 women with CNSLBP participated in this study for eight weeks in three groups: GEs, GEs with CFT, and control. Pain, QoL and muscle endurance were evaluated by visual analogue scale (VAS), SF-36 questionnaire, and Biering-Sorensen test, respectively. Mixed-model repeated measure test with repeated measurement design was used for data analysis.
Results: The results revealed a significant difference in the investigated variables between the pre-test and post-test for the intervention groups, but no difference was seen in the control group.
Discussion and final conclusion: The group of GEs combined with CFT distinguished itself significantly from the group of GEs in the comparison of the factors of physical performance, emotional health, and general health from sub-sections of QoL, and also muscular endurance. According to the results, it is recommended that women with CNSLBP use GEs in combination with CFT to reduce pain, improve QoL, and increase muscle endurance.

Abstract

This study investigates the impact of an anterior cruciate ligament (ACL) injury prevention program on the performance of elite female kabaddi players. Given the debilitating consequences of ACL injuries, the primary aim is to evaluate the effects of an eight-week prevention program on improving the performance of these athletes. This quasi-experimental research was conducted on 27 elite female kabaddi players (aged 18 to 24 years), who were divided into intervention and control groups. The intervention group underwent an eight-week injury prevention training program. The tests included T-test, 20-meter run, Y-balance test, flexibility, hopping, and movement screening. Data analysis was performed using Levene's test and ANCOVA. The results of the ANCOVA indicated that the intervention group scored significantly better than the control group in the Y-balance test for both the right (p=0.002) and left (p=0.001) legs, single-leg hopping (right leg: p=0.004 and left leg: p=0.001), crossover hopping for the right leg (p=0.023), and the sit-and-reach flexibility test (p=0.003). However, no significant differences were observed in the speed, agility, triple hopping, and functional movement screening (FMS) tests. Results: The findings suggest that the eight-week PEP program has a significant impact on dynamic balance for both the right and left legs, hopping (single-leg and crossover hopping for the right leg), and hamstring and lower back flexibility in elite female kabaddi players. However, it did not have a significant effect on left leg hopping, speed, agility, or FMS scores.
