- 概要（英）
- Purpose : Repeated-sprint training in hypoxia (RSH) has been shown to provide greater performance benefits than similar training in normoxia (RSN), whereas little is known regarding beneficial effects of RSH following a block of RSN. This study aimed to determine adaptive responses to “top-up” RSH. Methods : After pretesting, 15 male university basketball players completed 6 RSN sessions (2 sets of five to seven 6-second cycle sprints, 30-second intersprint, and 5-min interset recovery), followed by midtesting. Participants were then allocated to either hypoxic (HYP, n = 8) or normoxic (NOR, n = 7) group and completed 6 “top-up” sessions (3 sets of identical protocol), with 5 RSH (3000 m) plus 1 RSN in HYP and 6 RSN in NOR. Six-second and incremental cycle tests were performed to determine 1-second peak power (PP <sub>6s</sub> ), 6-second mean power (MP <sub>6s</sub> ), maximal aerobic power (MAP), and peak oxygen uptake ( ) at pre, mid, and post. Repeated-sprint ability (PP <sub>RSA</sub> ; averaged peak power over 10 sprints) was assessed during sessions 2, 6, and 12 in normoxia. Results: A 2-way mixed analysis of variance revealed main effects of time ( P < .05, partial η <sup>2</sup> = .349–.537) in all test variables (PP <sub>6s</sub> : Δ 10.6% [13.8%], MP <sub>6s</sub> : Δ 12.2% [13.6%], MAP: Δ 5.3% [4.3%], : Δ 6.1% [5.5%]) without time-by-group interaction, whereas neither group improved PP <sub>RSA</sub> . Conclusions: Twelve sessions of repeated-sprint training improved anaerobic and aerobic capacities in male basketball players, with no additional benefit of hypoxic exposure during the second training phase, suggesting increased training volume may have outweighed the environmental factor.
