High-intensity interval training (HIIT) in junior and adult soccer has been shown to improve oxygen uptake ([latin capital V with dot above]o2) and enhance soccer performance. The main purpose of this study was to examine the short term effects of a 5-week HIIT vs. high-volume training (HVT) program in 14-year-old soccer players regarding the effects on [latin capital V with dot above]o2max and 1,000-m time (T1000) and on sprinting and jumping performance. In a 5-week period, 19 male soccer players with a mean (SD) age of 13.5 ± 0.4 years performed HIIT at close to ~90% of maximal heart rate. The HVT intensity was set at 60-75% of maximal heart rate. [latin capital V with dot above]o2max increased significantly (7.0%) from pre to post in HIIT but not after HVT. T1000 decreased significantly after HIIT (~-10 vs. ~-5 seconds in HVT). Sprint performance increased significantly in both groups from pre to posttesting without any changes in jumping performance.
