Eight weeks of supervised endurance training in competitive cyclists significantly increased ventilatory threshold and VO2max, and decreased 40-km time-trial time (P<0.05).
Does 8 weeks of supervised endurance cycle training improve oxygen uptake kinetics in previously trained competitive cyclists?
Eight weeks of supervised endurance training improves oxygen uptake kinetics and performance in already trained competitive cyclists.
p-value: p=<0.05
The aim of this study was to determine the alterations in oxygen uptake kinetics following endurance training in previously trained athletes. Sixteen competitive cyclists completed 8 weeks of supervised endurance cycle training. Ventilatory threshold, maximal oxygen uptake (VO2max), oxygen uptake kinetics and simulated 40-km time-trial tests were performed three times over a 4-week period before training, and then after 4 and 8 weeks of training. The protocol for measuring oxygen uptake kinetics consisted of three square-wave increments from unloaded cycling to a power output of 78 W followed by a single increment from 78 to 156 W. No significant differences in any variables were observed over the pre-training period. The ventilatory threshold and VO2max increased, and the time for 40 km decreased (P < 0.05) with training. Shorter VO2 time constants and lower heart rates were observed during the protocol for measuring oxygen uptake kinetics (same absolute power output) post-training. These results indicate that oxygen uptake kinetics may be improved with endurance training in previously trained athletes.
Norris et al. (Thu,) conducted a other in Competitive cyclists (n=16). Supervised endurance cycle training vs. Pre-training baseline was evaluated on Ventilatory threshold, maximal oxygen uptake (VO2max), oxygen uptake kinetics, and simulated 40-km time-trial tests (p=<0.05). Eight weeks of supervised endurance training in competitive cyclists significantly increased ventilatory threshold and VO2max, and decreased 40-km time-trial time (P<0.05).
