摘要：Interval training at race-specific high cadences improves endurance cycling performance, but there is evidence that adding resistance to reduce the cadence might be more effective. AIM. To determine the effect of high-resistance interval training on endurance performance of male cyclists during the competition phase of a season. METHODS. In a randomized controlled trial, 10 cyclists in a control group maintained usual training and competing while 12 cyclists in an experimental group replaced part of their usual training with high resistance interval training twice weekly for 8 wk. Mean power in a 40-km simulated time trial, maximal oxygen consumption (VO2max), incremental peak power, body composition, and leg strength were measured before and after training. RESULTS. Relative to control training, there were clear beneficial effects of resistance training on 40-km mean power (7.6%, 90% confidence limits ±5.0%). There were also clear beneficial effects on incremental peak power (3.5%, ±4.2%), VO2max in ml.min‑1.kg‑1 (6.6%, ±7.0%), and sum of 8 skinfolds (‑12%, ±11%). Effects on body mass (‑1.6%, ±1.9%) and thigh muscle area (0.6%, ±2.7%) were possibly trivial. Effects on VO2max in L.min‑1 and three measures of isokinetic leg strength were unclear, owing to large errors of measurement. CONCLUSIONS. High-resistance interval training produces a major enhancement in endurance power of athletes in the competitive season. The benefits of this form of training should transfer to competitive performance
