The study aimed to evaluate the effects of 1 vs. 2 sessions per week of equal-volume sprint training on explosive, high-intensity and endurance-intensive performances among young soccer players. Thirty-six young male soccer players were randomly divided into 2 experimental groups that performed either a single weekly sprint training session (ST1, n = 18, age: 17.2 ± 0.8 years) or two weekly sprint training sessions (ST2, n = 18; age: 17.1 ± 0.9 years) of equal weekly and total volume, in addition to their regular soccer training regimen. Linear sprinting (10 m, 20 m, 30 m, and flying 10 m), T-test agility, countermovement jump (CMJ) and maximal oxygen consumption were assessed one week before (T1), in the middle (T2) and immediately after the 10 weeks of training (T3). A large magnitude and statistically significant main effect for time was found in all the assessed variables after both training interventions (all p < 0.001; ES ≥ 0.80). No main effect was observed between the 2 groups at any time in linear sprinting, T-test or CMJ test (p > 0.05; ES < 0.20). A significant interaction effect (F = 4.05; p = 0.04, ES = 0.21) was found for maximal oxygen consumption with ST2 inducing better performance than ST1 (p = 0.001; ES = 1.11). Our findings suggested that the two sprint training frequencies were effective in enhancing explosive, high-intensity and endurance-intensive performances. However, it is recommended for coaches and fitness coaches to use a biweekly sprint training modality as it was found to be more effective in improving endurance-intensive performance.
该研究旨在评估每周进行1次与2次等容量冲刺训练对年轻足球运动员爆发力、高强度和耐力密集型表现的影响。36名年轻男性足球运动员被随机分为2个实验组，除常规足球训练方案外，一组每周进行1次冲刺训练（ST1，n = 18，年龄：17.2±0.8岁），另一组每周进行2次冲刺训练（ST2，n = 18；年龄：17.1±0.9岁），两组每周和总训练量相等。在训练前1周（T1）、训练中期（T2）和训练10周后立即（T3）评估直线冲刺（10米、20米、30米和助跑10米）、T字测试敏捷性、反向移动跳（CMJ）和最大摄氧量。两种训练干预后，所有评估变量在时间上均呈现出较大幅度且具有统计学意义的主效应（所有p < 0.001；效应量≥0.80）。在直线冲刺、T字测试或CMJ测试中，两组在任何时间均未观察到主效应（p > 0.05；效应量< 0.20）。对于最大摄氧量，发现了显著的交互效应（F = 4.05；p = 0.04，效应量 = 0.21），ST2组的表现优于ST1组（p = 0.001；效应量 = 1.11）。我们的研究结果表明，两种冲刺训练频率均能有效提高爆发力、高强度和耐力密集型表现。然而，建议教练和体能教练采用每两周一次的冲刺训练方式，因为发现这种方式在提高耐力密集型表现方面更有效。
