The primary objective of this study was to assess the efficacy of measuring both aerobic and anaerobic power in a60-second, maximal effort test. It was hypothesized that oxygen consumption increases rapidly during maximal effort andmaximal oxygen consumption (VO2 max) may be reached in one minute. Fifteen Greek competitive kayakers performed thefollowing tests: 1) practice 60-second maximal exertion test; 2) standard incremental workload VO2 max test; 3) Wingateanaerobic power test (WAT); 4) VO2 measured during 60-second maximal exertion test (60-SEC); and 5) VO2 measuredduring 75-second maximal exertion test (75-SEC). All tests were performed on a wind-braked kayak ergometer. Hydrostaticweighing was performed to determine percent body fat. Peak oxygen consumption values for the 60-SEC (53.4 ml·kg-1·min-1,92% VO2 max), and 75-SEC (52.6 ml·kg-1·min-1, 91% VO2 max) tests were significantly lower than VO2 max (58.1 ml·kg-1·min-1). During the 75-SEC test, there was no significant difference in percentage VO2 max from 30 seconds to 75 seconds,demonstrating a plateau effect. There were no significant differences in peak power or relative peak power between the Wingate, 60-SEC, and 75 SEC tests while, as expected, mean power, relative mean power, and fatigue index were significantly different between these tests. Power measures were highly correlated among all three tests. It was concluded that VO2 max was not attained during either the 60-SEC nor 75-SEC tests. Furthermore, high correlations in power output forWAT, 60-SEC, and 75-SEC precludes the necessity for anaerobic tests longer than the 30-second WAT. |
