Introduction Maximal oxygen consumption (VO 2MAX) is an objective measurement of the human body’s ability to perform aerobically. Future research should look into modifying the resistances of the SALE protocol to be adapted to the subject's body weight and fitness level to determine if this elicits a higher VO 2MAX.ġ. The main finding is the addition of arm-ergometry to leg-ergometry produced lower VO 2MAX and test length compared to a treadmill test. VO 2MAX values were more similar for females than males (F(1, 45) = 5.08, p = 0.03). The ratio of SALE/TM results ranged from 68.9-104.6%. Heart rate at VO 2MAX ( p = 0.31), was not different between tests. 41.0 ± 8.0 ml/kg/min, respectively p < 0.05), and total length of VO 2MAX test was longer for TM than SALE (11.1 ± 2.1 vs 7.9 ± 3.2 min, respectively p < 0.05) however, the tests were highly correlated ( r = 0.92). VO 2MAX was higher for TM than SALE (45.6 ± 8.7 vs. Forty-seven college-aged individuals (female: n=27) volunteered for this study, completing both TM and SALE VO 2MAX tests. The purpose of this study was to compare a simultaneous arm and leg ergometry (SALE) testing protocol to a TM VO 2MAX test. Very few studies have examined the idea of incorporating arm cycling combined with leg cycling in VO 2MAX testing. The purpose of VO 2MAX testing is to determine a person's aerobic capacity and has been shown to elicit the highest response in treadmill (TM) testing.
The data suggest that this CE test gives a reliable and valid estimate of VO2 max.Maximal oxygen consumption (VO 2MAX) testing can be performed on a variety of modalities ranging from treadmills to rowing ergometers. Test-retest reliability coefficients for intensity (watts) on the maximal predictive CE test were 0.95 and 0.81 for males and females respectively (p less than 0.01). The VO2 max predicted from the Astrand-Rhyming test correlated significantly with VO2 max measured by CE and TM only in the male group. Correlation coefficients for VO2 max predicted from the maximal predictive CE test and VO2 max measured directly by CE and TM were 0.89 and 0.87 for males and 0.88 and 0.83 for females (p less than 0.01), respectively. When compared to TM VO2 max, VO2 measured during the final 30 s of the maximal predictive CE test was 16.0% and 16.2% lower for males and females respectively compared to VO2 max determined by the direct CE test, it was lower by 2.9% for males and 5.2% for females. This was compared with two direct measures of VO2 max and with the submaximal predictive test of Astrand-Rhyming. The highest work rate achieved was recorded as the endpoint of the test and used to construct regression equations to predict VO2 max. The test consisted of pedalling a cycle ergometer (Monark) at 75 rev X min-1, beginning at an intensity of 37.5 watts and increasing by this amount each min until the subject could no longer maintain pedal rate.
A maximal predictive cycle ergometer (CE) test for estimating maximal oxygen uptake (VO2 max) was evaluated in 15 male and 12 female subjects.
