SummaryThe aims of this study were (a): to compare maximal physiological responses (maximal heart rate: HRmax and blood lactate concentration: [La-]) and maximal aerobic speed (MAS) achieved during a gold standard test (T-VAM) to those during a new test entitled: the 150-50 Intermittent Test (150-50IT), and (b): to test the reliability of the 150-50IT. Eighteen middle-distance runners performed, in a random order, the T-VAM and the 150-50IT. Moreover, the runners performed a second 150-50IT (retest). The results of this study showed that the MAS obtained during 150-50IT were significantly higher than the MAS during the T-VAM (19.1 ± 0.9 vs. 17.9 ± 0.9 km.h−1, p < 0.001). There was also significant higher values in HRmax (193 ± 4 vs. 191 ± 2 bpm, p = 0.011), [La-] (11.4 ± 0.4 vs. 11.0 ± 0.5 mmol.L−1, p = 0.039) during the 150-50IT. Nevertheless, significant correlations were noted for MAS (r = 0.71, p = 0.001) and HRmax (r = 0.63, p = 0.007). MAS obtained during the first 150-50IT and the retest were not significantly different (p = 0.76) and were significantly correlated (r = 0.94, p < 0.001, intraclass correlation coefficient = 0.93 and coefficient of variation = 6.8 %). In conclusion, the 150-50IT is highly reproducible, but the maximal physiological responses derived from both tests cannot be interchangeable in the design of training programs.

The purposes of this study were to describe and compare the techniques used by elite world triple jumper and the Algerian elite team to determine the impact of distribution modality phases allowing the elite to exceeds 17-meter. Our subjects were two world elite 2009 and two Algerian national elite 2013. In the lack of new technology Modern measuring instruments kinematics or kinetics, our study based in measure of the Phase distribution ratio as measure of Stride length Jump distance. That literature review two schools, the Russian technique (which emphasizes the hop phase) and the Polish technique (which emphasizes the jump phase). Our aims for this study are: Are there any statistically significant differences between the results of the samples in the distance achieved? Are there any statistically significant differences between practical Ratio relative distances (world 2009-national 2013)? Are there any statistically significant differences between Stride length phase distances (world 2009-national 2013)? For that, we have chosen the analysis of variance and correlation of the distances achieved in each of the phases with the official distance of jumper and "T" student to compare implementation distribution of phases (hop, step and jump) with the results accuses. Based on the practices and weaknesses of elites in practice, we confirm: (1) All the samples practice the Russian technique as model in the distribution of the phase ratio; (2) The problem of our elites is in the hop phase distribution and its relationship with other phases; (3) Improve achieve horizontal vertical velocity in hop phase as solution.

Aerobic capacity is a vital factor for soccer achievement. Disclose by professionals over VO2max of 60 ml/kg/min recommended as the minimum fitness condition for male soccer players to play at leading levels. Founded on the principle kinetics analyse, which confirms that among competitive soccer players, wing-backs and central midfielders cover long distances at high speed, then by defenders and attackers. Our objective is to test 180 well-trained male senior player, first division Algerian Championship. Dived biased on their postgame. Controlled at the end of the preparatory phase before the start of the Algerian Championship 2016-2017. Tested by Cooper tests to estimate their VO2max and body fat percent (BFP) and index body mass (BMI). As simple tools to control their optional body weight relates to their aerobic fitness. Our results support the uniform of Algerian training programmes aerobic capacity. Conclude through the present founded on kinetics analyse, which confirmed that in competitive soccer players, wing-backs and central midfielders cover long distances at high speed, then by defenders and attackers. Our results show that VO2max L/min was insignificant based on the postgame, where this result confirms to users the negative effect of the moderate-intensity exercise intervention and its consequences on develops of recommended levels of VO2max relative to proper individuals programme fitness helping players to manage body weight or stroke. Disclose by professionals over VO2max of 60 ml/kg/min recommended as the minimum fitness condition for male soccer players to play at leading levels.

The purpose of the current study was to evaluate the Aerobic endurance training as indicators of physiological training status among male soccer players. A total of 138 well-trained first division soccer players under 18 years were tested. Testing was based on the Cooper test as a one of simple tests to estimate VO2max. BMI and BFP as valued anthropometric measurements to control body change relative to maximal oxygen consumption during dynamic exercise with large muscle groups benefit training time soccer training experience. Performance in this experience was based on the subjection that 60 ml/kg/min of VO2max is the minimum fitness requirement for male soccer players to play at the elite level. Admit in this study as a protocol to categorise our sample into two groups (up and under the range VO2max ± 60 ml/kg/min) and it was based on statistics applied and the design used. Our results highlighted the importance of aerobic performance up to 60 ml/kg/min as the minimum fitness requirement to enhance the players' aerobic capacity allied to maximal heart rate relative to BFP levels as a better parameter in comparison with BMI for the prediction of low VO2max concomitant to the physiological training status as requests soccer performance demand.
