Abstract
The purpose of this study was to investigate eight weeks of dynamic neuromuscular stabilization exercises on movement performance indicators, walking kinematics and lower limb damage in students with weak lumbopelvic control. Methodology: 30 female students with a mean age of 16.65±0.75 years, height of 161.80±4.11 cm, weight of 62.70±5.64 kg who had weak lumbopelvic control were purposively selected and randomly divided into two experimental groups n=15 and control groups n=15. The experimental group performed the neuromuscular for eight weeks, three sessions per week for 60 minutes, while the control group did not receive the intervention to assess lumbopelvic control a biofeedback device was used for jumping, static balance was used for stork test, dynamic balance was used for Y test, landing error was used for landing Error Scoring System Test, and lower limb motor function was used for tests (single-leg jump test, triple jump test, 6 - meter jump test in time, and cross jump test results: The present study showed that the effect of DNS exercises on motor performance indices 0.012, gait kinematics 0.001, and lower limb injury 0.012 was significant P<0.05.

Abstract
Background: Metabolic dysfunction-associated fatty liver disease (MAFLD) is the most prevalent chronic liver disorder. Aerobic exercise is a key non-pharmacological strategy for MAFLD management, yet the impact of different training intensities remains unclear. This study investigated the effects of eight weeks of high-intensity interval training (HIIT) and moderate-intensity continuous training (MICT) on non-invasive liver indices, body composition, and metabolic markers in middle-aged women with MAFLD.
Methods: In this clinical trial, 41 women with MAFLD (41.39 ± 6.16 years; BMI: 32.14 ± 3.36 kg/m²) were randomly assigned to HIIT, MICT, or control groups. MICT involved 30–45 minutes at 60–70% heart rate reserve, while HIIT included 4–6 bouts of 30 seconds at 50–100–110% of maximal aerobic speed. Body composition (weight, BMI, BAI, ABSI), steatosis (HSI, FSI, LFS), fibrosis (NFS, NRS, FIB-4, FIB-5, APRI), and metabolic indices (LAP, CMI) were measured before and after the intervention. Statistical analyses included paired t-tests, one-way ANOVA, and GLMRM (p < 0.05).
Results: Both HIIT and MICT significantly reduced weight, BMI, BAI, and LFS. ABSI increased in control. HSI decreased following HIIT, while FSI decreased after MICT. Among fibrosis indices, only FIB-5 showed a significant reduction in MICT compared to HIIT, and NRS decreased in MICT compared to control. LAP decreased in both training groups relative to control, whereas CMI decreased only in MICT.
Conclusion: Although MICT demonstrated superiority in certain parameters, HIIT elicited comparable effects in a shorter duration and may represent an efficient strategy for the clinical management of MAFLD.

Abstract
One of the most important success factors in most athletic competitions, receiving aerobic power (speed,
agility and jumping) high. Basketball is a great combination of short and long term activities that depend on
aerobic fitness. Anaerobic fitness of many players during the match determines tactical the performance.
The purpose of the present study to investigate the effects of strength exercises on anaerobic power and
some the variables related Traband it. The subjects consisted of 30 basketball players Young, randomly into
two equal groups of 15 subjects (experimental and control) were randomly assigned to 6 weeks and 3
sessions the Exercises were done in a week. To analyze the data, independent samples T-test and paired
sample T-test used at a significance level p ≤ 0/05. Later for six weeks of exercises, significant differences
between the records obtained from the anaerobic power the variables (speed, agility, vertical jump) were
observed between the two groups. The present study showed that the strength exercises with the variables
Traband improve anaerobic power in young basketball players and And according to the results of seem to
exercises Traband useful method for improving performance of the anaerobic the athletes.

Abstract
Mental fatigue is usually caused by long-term cognitive activities; in a way that reduces cognitive performance and leads to changes in functional activities. Therefore, the purpose of this study was to investigate the effect of a session of Swedish relaxation massage and meditation in controlling mental fatigue on reactive balance and Lower extremity function of amateur athletes. In this study, 16 female physical education athletes were purposefully selected as a sample based on the study entry criteria, and were subjected to mental fatigue protocol (45 minutes of cognitive activity (Stroop test)), Swedish relaxation massage (30 minutes) and meditation (30 minutes) with a time interval of 48 hours. Reactive balance was evaluated with Y test with automatic lights and, Lower extremity function was evaluated with single hop for distance, triple hop for distance, meter-6 and hop crossover-triple distance tests. Repeated analysis of variance test was used to check intra-group changes.The findings showed that there is a significant difference between the average scores of reactive balance and lower limb performance of the subjects when comparing the post-test of mental fatigue with the post-test of massage and meditation (P<0.05). Also, there is a significant difference between the subjects' scores comparing massage and meditation for reactive balance and body function (P<0.05).In order to prevent sports injuries in athletes, Swedish relaxation massage and meditation can be used as an intervention to speed up the recovery of mental fatigue and improve reactive balance and body function.
