简要总结
This study aims to investigate the effects of an 8-week high-intensity interval training (HIIT) program on aerobic capacity, anaerobic power, blood lactate levels, and sprint performance in young male soccer players. Twenty-four volunteer U19-category soccer players from Sivasspor A.Ş. were randomly allocated into an experimental group (n=12), which performed HIIT three days per week for 8 weeks in addition to their regular training, and a control group (n=12), which continued only their routine training program. Anthropometric measurements, resting heart rate, aerobic performance (Yo-Yo IRT1), anaerobic performance (RAST), and blood lactate levels were assessed before and after the intervention period.
详细描述
This experimental study was designed to examine the effects of an 8-week HIIT protocol, applied three days per week, on selected physical performance parameters in youth soccer players. Participants were randomly divided into an experimental group and a control group. Height was measured using a Harpenden stadiometer and body weight using a digital scale. Aerobic performance was assessed using the Yo-Yo Intermittent Recovery Test Level 1 (Yo-Yo IRT1), with heart rate monitored via a Polar Team Pro 2 device. Anaerobic performance was evaluated using the Running-based Anaerobic Sprint Test (RAST). Blood lactate concentration was measured using a portable lactate analyzer from finger-tip capillary blood samples at rest and following the RAST protocol. All measurements were taken as pre-test and post-test assessments, before and after the 8-week intervention period. The study was approved by the local Clinical Research Ethics Committee (2021/243) and conducted in accordance with the Declaration of Helsinki. Written informed consent was obtained from the parents/legal guardians of all participants prior to testing.

研究组 & 干预措施
HİİT group
Participants in this arm continued their regular soccer training and additionally performed high-intensity interval training (HIIT) three days per week for 8 weeks.
干预措施: High-Intensity Interval Training (HIIT) (Behavioral)
Control Group
Participants in this arm continued only their existing routine soccer training program, without any additional HIIT intervention, for the 8-week study period.
结局指标
主要结局
Change in Maximal Oxygen Uptake (VO2max)
时间窗: Baseline and after 8 weeks
VO2max was estimated using the Yo-Yo Intermittent Recovery Test Level 1 (Yo-Yo IRT1), based on total distance covered.
Change in Anaerobic Power
时间窗: Baseline and after 8 weeks
Anaerobic power (average power and peak power) was assessed using the Running-based Anaerobic Sprint Test (RAST).
Change in Sprint Performance
时间窗: Baseline and after 8 weeks
Sprint time was measured over a 35-meter distance using photocell timing gates during the RAST protocol.
Change in Blood Lactate Concentration
时间窗: Baseline and after 8 weeks
Blood lactate levels were measured at the 1st and 5th minute post-exercise using a portable lactate analyzer.
