Overhead athletes require a delicate balance of shoulder mobility and stability in order to meet the functional demands of their respective sport. While musculoskeletal symptoms (LBP) [1] is one of warning against the consequences recorded in abnormal posture, bending, twisting, gardening and exercise levels among the sportsmen. Based on this theorem, the current study aims to determine the strong factor which affects mobility and stability among soccer players under 21 years. Material: 163 male players qualified from the Algerian football championship, engaged in the present study, selected by the intentional manner their average age 19,56±1.22 years. They were tested by saving tests (Body Fat Percentage (BFP)-Abdominal test (Abdo)-Modified Bass Test of Dynamic Balance (DB) and standing balance (SB)). As a statistical model, we chose regression analysis to predict the superiority of the variables chosen in the current study. Results: Based on the analysis statistics, we confirm: The high percentage of BFP is a great risk on the levels strengthens abdominal. The maintenance of stability (SB) depends on the additional BFP associated with the BMI ratio as being higher factors predicting the total amount of body weight related to the risks of instability. Maintaining dynamic mobility (DB) with respect to the displacement of the centre of gravity and its base support in the motion chain is based on excess body fat (BFP) in relation to body mass index (BMI) and Abdominal muscle strengthening levels (ABDO), as higher factors predicting the amount of weight gain. Conclusions: Founded on the variances acquired by the search, we highlight the relationship between body mass index (BMI) and body fat percent (BFP) as betters index predicting the influence of total amount body weight on mobility and stability among soccer players up to 21 years age. Evidence guide us to recommend, the evaluation of body composition as a part of body management and control. Where strong relationships between BMI and BFP suggests the anomalies postural, muscle coordination, movement control, balance and awareness of body position in both the tests.

Abstract:The play has been shown to help children adjust to the school setting and to enhance children's learning [1]. Since this theory, the current study was designed to examine the significance of mechanical effects of intra-abdominal on posture/balance control among the Algerian Childhood Primary Schools. Since our teachers emphasise the good classroom settings as a discipline pedagogical aspect of success learning. While High- Based on the differences acquired by the research team, we emphasise that prolonged periods classroom settings Primary Schools increase the intra-abdominal which owing to the weakness of skeletal muscle fatigue and abnormal pathological alignment. While as a recommendation pedagogy practised, we suggested to our teachers, who work with these children to know that the balanced posture requires more energy in the class, Considering that our student seat more than 6 hours a day, 30 per week, and 120 per month 1080 per year in Algerian primary schools.

Objective: This study was designed to analyze the impact of Algerian judo competition modality on vertical jump performance, grip strength test and perceived effort responses.Method: For the proposed 34 male judoka athletes participated in the present study. All their performance was verified based on the Algeria modality competition that consisted form 4 min fight separated by 15 min of rest. Judo-Ji grip strength tests (JGST), countermovement jump (CMJ) and rate of perceived exertion (RPE) were measured before and after each competition, while RPE of specific areas was assessed after three competitions. ANOVA for repeated measures was used to compare strength parameters after each contest with the level of significance set at 5%. Result: our results showed a significant decrease of jump height (p = 0.001) and vertical impulse in the CMJ (p = 0.00), as well as a reduction of the number of reps in the JGST (p < 0.00). In the opposite of significant increase of RPE throughout the competition (p < 0.00), not RPE between the upper and lower body (p = 0.00). Conclusion:We conclude that Algerian modality judo competition generated a decrease of performance in both upper and lower limbs and provoked a progressive increase in the effort perception over the fighter.

Background: Walking is a fundamental and affordable physical activity that improves entire body and helps women lose weight. However, some studies suggest that walking alone has little or no effect on improving or maintaining body mass and fat mass at the hip and spine. The objective of this study is to estimate the effect of walking intensity (interval training vs. traditional cardio) on weight loss after childbirth. Material and methods:A total of 39 postpartum women [19 experimental subjects (ES) and 20 controls (CS)] participated in this study. Their homogenates were calculated based on their average age of 25 ±2.54 years. BMI obese moderate and waist circumference at high-risk, first deliveries to the same educational and social status. The subjects participated in this study to lose excess weight within three months after childbirth. Results:Our results indicate that interval training with fast walking is a powerful tool for developing successful strategies for managing weight loss. Conclusions:We recommend that postpartum women, who use walking to amplify their weight loss, use the following exercise schedule: at least three sets of 400 m (wf ≈ SR) × 5 per day, nine 400 m (wf ≈ SR) × 5 sets per week, and 36 sets of 400 m (wf ≈ SR) × 5 per month.
