Measuring V02peak is an important health assessment used to indicate cardiorespiratory fitness, prescribe exercise, and diagnose heart abnormalities (2,12). Utilizing the muscles of the upper body, the new StairMaster kayak ergometer is ideal for measuring V02peak on people with lower extremity disorders and those whose occupational or recreational activities rely primarily on the muscles of the upper body (16). Twenty-four healthy college-aged (17-31 years) males and females were screened, gave informed consent, and received orientation to experimental procedures prior to participation in the study. Subjects performed two maximal exercise bouts on the kayak incremental protocol and one on the treadmill incremental protocol. Pearson's r correlation estimated the stability-reliability coefficient of the kayak protocol to be 0.84.
Pearson's r correlation estimated the relationship of the kayak protocol to the treadmill protocol to be 0.69. Given performance on the kayak ergometer, the predictive equation for treadmill performance was Y = 11.2605 + 1.02748X (r = 0.48). Body mass index and forearm circumference were found to be adequate predictors of kayak performance using the equation 45.2 - 1.60 BMI + 1.03 Forearm (~ 0.49).
Although the kayak incremental protocol demonstrates adequate test-retest reliability for measuring V02peak, it has only a fair relationship to the gold standard of uphill treadmill running. The kayak incremental protocol, therefore, is generally best suited for those who, due to lower extremity complications, are unable to perform traditional modes of testing, or for those whose occupational or recreational activity is dominated by the upper body.
