BACKGROUND/OBJECTIVE: This study aims to compare the effect of sprint distance and repetition number on performance, physiological responses, and energy systems contributions.
Eighteen male university league soccer players (age: 19.9 ± 1.6 years, height: 177.9 ± 4.7 cm, body mass: 72.4 ± 6.3 kg, percentage body fat: 8.9 ± 1.8, training experience: 7.4 ± 1.6 years) completed two different repeated sprint protocols: 20 × 20 m (20 × 20) and 10 × 40 m (10 × 40) with 15s and 30s rest intervals, respectively. Oxygen uptake (VO) were measured during the rest, exercise, and recovery phases. Rest and peak blood lactate concentrations were determined. Using VO and lactate values, the energy system contributions were calculated using a mono-exponential model and mathematical calculations. Energy systems contributions and total energy expenditure (TEE) were calculated both for the entire protocol (overall) and for the sprints only.
Ratings of perceived exertion (RPE), peak and mean heart rate (HR) responses were significantly higher in the 20 × 20 whereas lactate response was higher in the 10 × 40. TEE was similar between the 10 × 40 (586.3 ± 60.8 kJ) and 20 × 20 (595.6 ± 57.5 kJ). For overall estimations, the 10 × 40 and 20 × 20 presented similar results of oxidative (47.5 ± 5.4 vs 45.7 ± 5.1 kJ min) and phosphagen (44.7 ± 5.4 vs (42.9 ± 4.8 kJ min) systems contributions whereas glycolytic contribution was higher in the 10 × 40 (15.5 ± 2.2 vs 12.8 ± 2.3 kJ min). For sprints only estimation, the phosphagen (257.6 ± 31.5 vs 225.2 ± 28.2 kJ min), glycolytic (89.4 ± 13.4 vs 67.3 ± 12.5 kJ min), and oxidative (76.9 ± 6.9 vs 72.0 ± 7.9 2 kJ min) systems contributions were higher in the 10 × 40.
Although HR and RPE responses were higher in the 20 × 20, phosphagen (during sprints) and glycolytic (during both sprints and overall protocol) were higher in the 10 × 40 protocol. Therefore, the 10 × 40 protocol seems more reasonable for developing or evaluating the anaerobic systems.
背景/目的：本研究旨在比较冲刺距离和重复次数对运动表现、生理反应以及能量系统贡献的影响。
18名男性大学联赛足球运动员（年龄：19.9±1.6岁，身高：177.9±4.7厘米，体重：72.4±6.3千克，体脂百分比：8.9±1.8，训练经验：7.4±1.6年）完成了两种不同的重复冲刺方案：20×20米（20×20）和10×40米（10×40），休息间隔分别为15秒和30秒。在休息、运动和恢复阶段测量摄氧量（VO）。测定休息和血乳酸峰值浓度。利用VO和乳酸值，通过单指数模型和数学计算来计算能量系统贡献。计算整个方案（总体）以及仅冲刺阶段的能量系统贡献和总能量消耗（TEE）。
自觉用力程度（RPE）、心率峰值和平均心率（HR）反应在20×20方案中显著更高，而乳酸反应在10×40方案中更高。10×40方案（586.3±60.8千焦）和20×20方案（595.6±57.5千焦）的TEE相似。对于总体评估，10×40和20×20方案的氧化系统贡献（47.5±5.4对45.7±5.1千焦/分钟）和磷酸原系统贡献（44.7±5.4对42.9±4.8千焦/分钟）相似，而糖酵解贡献在10×40方案中更高（15.5±2.2对12.8±2.3千焦/分钟）。仅对于冲刺阶段评估，10×40方案的磷酸原系统贡献（257.6±31.5对225.2±28.2千焦/分钟）、糖酵解系统贡献（89.4±13.4对67.3±12.5千焦/分钟）和氧化系统贡献（76.9±6.9对72.0±7.9千焦/分钟）更高。
尽管20×20方案中的HR和RPE反应更高，但10×40方案中的磷酸原（冲刺期间）和糖酵解（冲刺和整个方案期间）贡献更高。因此，10×40方案对于发展或评估无氧系统似乎更合理。
