Objective: The training of middle-distance runners is based on intermittent exercises. However, no study has proposed intermittent test to assess endurance performance for middle-distance athletes. The aims of the present study are 1) to develop a new specific testing for middle-distance runners entitled the 180/20 intermittent athletic test and to examine the validity of this test as compared to a standard continuous test 2) to check whether the maximal aerobic speed obtained from the 180/20 intermittent athletic test is related to the 800-m performance. Methods: Nineteen male middle-distance runners (age: 21.3 ± 2.2 years, height: 1.75 ± 0.04 m, and body mass: 68.8 ± 3.8 kg) performed in a random order three field-tests: a standard test, the 180/20 intermittent athletic test and 800-m time-trial. The new test consisted of repeated 180m distance runs interspersed with 20m of active recovery performed until exhaustion. The speed is increased by 0.5 km.h-1 every 200 m. Results: The results of this study showed the maximal aerobic speed achieved during the new test was significantly correlated to the maximal aerobic speed determined from a standard test (r = 0.82, p < 0.05) with low agreement limits (-1.69–1.48 km.h-1) without systematic bias (-0.10 km.h-1). The maximal aerobic speed in new test was better correlated to the 800-m running performance than the maximal aerobic speed achieved during a standard test (r = -0.78 and r = -0.66, respectively). Conclusions: The 180/20 intermittent athletic test is a valid test for scheduling intermittent training sessions in middle-distance runners.

SummaryEctomorph often below the average weight characteristics by a “thin frame” and difficult to gain muscle mass and fat. According to similar studies to build their muscle mass under it is necessary to include adequate multiple joints and larger muscle groups in bodybuilding program, in this study by using a wheelchairs, when doing a pushed up. The aim of the study was to improve upper-body strength and endurance among 20 healthy ectomorph male students, selected by the intentional method, according to their weight, which did not correspond to their height. They were controlled while performing push-ups, flexed arm-hangs and chin ups. Our goal was to compare the impacts of two training proposed programs (Traditional with weight (CS) v’s wheelchair (ES)). The training programs were applied for 6-weeks with 15-minute warm-ups integrated through their regular PE basketball courses cycle planned in the second semester. Built on statistical apply, we confirmed that wheelchair is a tool that enhances the upper-body muscles of ectomorph-type better than traditional body-weight training. It was approved in the present study through the use of wheelchair push-up, as an excellent means to increase the upper-body muscle-building strength and endurance better than the classic method used by our PE teachers.

The objective of the current study is built in body fat as a predictor of ideal weight to promote health and fitness body weight. To test this hypothesis, we founded on the relationship between fat mass index vs index body mass composition to improve aerobic capacity as control of body weight. For the proposition, 60 women sports under 22. We're controlled by the cooper test as physiological parameter estimated VO2 max and the weight and height to estimate BMI and body fat as anthropometric measurements. Based on our database and analyses, we confirm the hypothesis, which argued that BMI alone should not be used to determine an "ideal" body weight. Since the level of VO2 max is the best predictor of aerobic capacity and adjusted fitness body weight based on the ratio of body fat among sportswomen. However, to develop an equation more studies are required to prove this hypothesis.

The criteria and methods for goalkeeper selection are more strict and complex than those of field players. Founded on its principles, the present study tried to examine the strengths and weaknesses of selection process practised by Algerian coaches. Interpret by Algerian scientists in their subjectivity in evaluating the amount of body fat and its effect on physical performance. Seen it's built with the naked eye. Confirmed by FIFA in two categories normal vs overweight, they should work harder under these conditions. For this proposal, eight teams from the leagues of Oran, Algeria Championship second division were involved in the study. Their goalkeepers were classified into the following groups: total (GK = 28), Main goalkeeper (MG = 14) and replacement goalkeeper (RG = 14). Tested at the end of the outward phase by penalty kicks test, ‘T’ Drill Test, Ruler Drop Test (TR) and anthropometric parameters (BH, BMI, BFP, BW). Backed on the applied statistical where our total sample is categorised in overweight, as well as no statistically significant differences between the two groups in all the comparisons practised. Our results confirm the weaknesses of traditional methods. Admit by similar studies in their subjective in evaluating the amount of body fat and its effect on physical performance correlate to anthropometric measurement.
