: High-intensity interval training (HIT) on VOpeak, peak aerobic power output and 5km time trial performance was suggested to be an efficient training strategy, and consecutive 3-day per week training for 3 weeks could provide similar training effects with non-consecutive days. The effects of consecutive 7-day HIT is still not clear. : To compare the consecutive 7-day training effects of HIT versus moderate-intensity continuous training (MCT), matched for training distance, on the endurance parameters of velocity of 4mmol·L-1 lactate threshold (4-LT), running economies (REs), maximal oxygen uptake (VOmax), velocity associated with VOmax (VOmax) and plasma activity of creatine kinase (CK) in young basketball players. : Randomised experimental research was used. : Eighteen male basketball players were randomly divided into HIT ( = 10) or MCT group ( = 8). Subjects conducted consecutive 7-days of treadmill training performing either HIT (7 repetitions, 2-min bouts at 90% VOmax, 1-min rest intervals) or MCT (continuous, 20.8 ± 1.0 min at 65% VOmax). Pre- and post-training, the 4-LT, REs at fixed speed of 2.0, 2.5 and 3.0 m·s-1, VOmax, VOmax, and CK activity of subjects were measured. : After training, the HIT group significantly improved 4-LT (3.2 ± 0.4 to 3.5 ± 0.5 m·s-1, < 0.05), REs (10.4-11.5%, < 0.05), and VOmax (4.1 ± 0.5 to 4.5 ± 0.8 m·s-1, < 0.05). The HIT group also showed significant increase in the activity of CK (148.1 ± 47.3 to 302.6 ± 68.2 U·L-1, < 0.05). : When training volume is matched, consecutive 7-day of HIT is more efficient than MCT for improving endurance determinants and has small extent of muscle damage for basketball players.
