When sport exercises are properly designed and integrated, using a multifaceted training approach can help achieve goals without the need for other interventions. Ankle balance strategy restores balance by moving the body around the ankle joint. The aim of the present study was to investigate the effect of eight-weeks of combined corrective exercises on the activity of of involved muscles in girls' ankle strategy with lower extremity pronation syndrome. Materials and Method: In the current semi-experimental study with pretest-posttest design and control group, 30 students, aged 13-16 years old, with lower extremity pronation syndrome were randomly divided into two groups of experimental (n=15) and control (n=15). Prior to and after eight weeks of training for 60 to 80 minutes, three times a week, we evaluated flat foot using Navi drop test, knee valgus using tibiofemoral angle measurement, tibialis anterior and medial gastrocnemius muscles Electromyography (EMG) activity on Biodex Balance while standing on dominant. Results: Covariance analysis showed a significant difference in tibialis anterior and medial gastrocnemius muscles EMG between the two groups in the posttests. Also, corrective exercises was found to be significantly different on tibialis anterior and medial gastrocnemius amount of muscles activity at posttest compared with pretest and had approximately 94% and 62%, respectively, effects on the EMG of these muscles in girls with lower extremity pronation syndrome (p=0,001) (p=0,026). Conclusion: It seems that corrective mixed exercises led to changes such as increased muscles activity in those responsible for balance control such as increase in the tibialis anterior muscle activity and decrease in the gastrocnemius muscle activity, which are related to the ankle strategy. So it is recommended that specialists and researchers consider corrective exercises in order to improve balance strategies in people with pronation syndrome.

The muscle fatigue was induced by repeated knee extension and flexion until exhaustion. The kicking motions of seven players were captured at 500 Hz using a three-dimensional cinematographic technique before and immediately after the fatigue protocol. We found the muscle fatigue declined the peak linear and angular velocity of the distal segment during kicking. This was most likely attributed to the reduced peak magnitudes of resultant moment and motion-depended interactive moment acting at the knee joint. These results indicated that the muscle fatigue not only declined the muscle force but also induced a worse inter-segmental coordination during kicking.

The increase of air pollution in indonesian big cities has resulted in serious health problems of their inhabitants. doing physical exercises in such conditions may affect health quality. This study aims to investigate the effects of physical exercises at public sports facilities exposed to particulate matter 2.5 (PM 2.5) on forced vital capacity (FVC) and blood lead levels among visitors of public sports centres in Bandung. Methods. A pretest-posttest randomized-group design was applied. overall, 30 people who visited public sports facilities were selected to participate on the basis of the inclusion criteria. The subjects were divided into 2 equal groups, the control and the experimental group. The experimental group performed physical exercises for an hour 3 times a week for 6 weeks under high PM 2.5 conditions. Meanwhile, the control group did not perform any physical exercise. The participants underwent anthropometric measurements at baseline, as well as spirometry (FVC) and blood lead tests before and after the intervention. PM 2.5 levels were also evaluated. Results. There was a significant increase (p < 0.001) in FVC and blood lead levels in the experimental group after 6 weeks of exercising in the evening at public sports facilities which were highly exposed to PM 2.5. Conclusions. Six weeks of routine and regular physical exercises at public sports facilities highly exposed to PM 2.5 increased blood lead levels, with no negative effect to body function in accordance with standard lead level values by the local health department.

Detailed data on Fr to reduce muscle fatigue and enhance performance in futsal athletes are still limited. The study aimed to assess whether Fr was a suitable recovery method for futsal athletes to enhance performance and reduce their lactic acid concentration. Methods. A total of 30 male futsal athletes participated in this study. They were randomly divided into 2 groups: 15 subjects assigned to the experimental (Fr) group practised foam roller exercises, while 15 individuals assigned to the control group were given slow jogging recovery. Both groups completed pre-and post-recovery tests for anaerobic capacity and agility. Blood lactate was measured before the experiment, immediately after the tests, and immediately after recovery. A 2 × 2 repeated measures analysis of variance (ANOVA) was used to calculate each parameter results. Results. In the post-recovery lactate concentration, the independent t-test revealed a significant decrease between pre-and post-test values in the Fr group (p = 0.033). conversely, an increase in lactate between pre-and post-test measurements occurred in the control group (p = 0.058). Furthermore, ANOVA revealed significant time × group interactions (p = 0.002) and a significant main effect for group (p = 0.001). Conclusions. Fr after exercise-induced muscle fatigue had an effect on the recovery of elite futsal players by increasing the rate of blood lactate clearance. There was no increase in performance in 20-m sprint or agility (t-test).
