• Resumen

  • This investigation compared supramaximal oxygen uptake interval training with continuous training in collegiate, national, and international class rowers. It was hypothesized that 6 supramaximal intensity sessions over 11 days would increase power on selected power measures. After 8 weeks of training for a new season, 10 heavyweight and 6 lightweight rowers were randomized into 2 groups. A ramp test to limit of tolerance to determine peak aerobic power (6 females: 25 W·min-1; 10 males: 30 W·min-1) and an all-out 3-minute test to determine peak power, 60-second power, critical power, and work above critical power (W') were performed before and after training. A supramaximal training session consisted of 10 cycles of 10-second work (140% peak aerobic power):5-second recovery followed by 8 minutes of active recovery, and repeated 6 times. The continuous group performed predominantly moderate intensity (below lactate threshold) training. All training was performed on rowing ergometers. Critical power increased pre-to-post supramaximal ([DELTA]7%) and continuous training ([DELTA]9%), respectively (336 ± 59W to 360 ± 59W; 290 ± 73W to 316 ± 74W; p <= 0.05), whereas the mean power output from all performance measures increased only after supramaximal training ([DELTA]7%) (464 ± 158W to 496 ± 184W; p <= 0.05). Testing also revealed decreased W' ([DELTA]21%) and 60-second power ([DELTA]4%) pre-to-post continuous training only (p <= 0.05). No differences (p > 0.05) in peak aerobic power or peak power were observed pre-to-post training in either group. In conclusion, after an 8-week preconditioning period, supramaximal interval training preserved anaerobic capacity compared with predominantly continuous training and elicited similar increases in critical power in rowers.
