在四个不同的测试日中，１０名非运动员的健康男性，随机以４０，６０，８０和１００ｒ／ｍｉｎ做极限水平递增负荷运动试验。结果显示：于运动负荷为４５，９０，１３５，１８０和２２５Ｗ时，踏车速率与Ｖ·Ｏ２分别呈抛物线样二项式相关关系。自４５Ｗ起，ｒ分别为０．９３，０．９１，０．８９，０．９２和０．９１（均Ｐ＜０．０１）。不同运动负荷下，最佳代谢踏车速率分别为５１．３，５４．６，５８．３，７２．３和８０．４ｒｐｍ，并与运动负荷呈高度直线相关（ｒ＝０．９３，Ｐ＜０．０１）。不同运动负荷下，１０名受试者的自选踏车速率分别为８４±６．５８，８３±５．８７，９２±５．１７，８０±７．４５和８３±９．７ｒ／ｍｉｎ，与最佳代谢踏车速率和运动负荷间无相关（ｒ为－０．１７和－０．３２，均Ｐ〉０．０５）。结果提示：在相同运动负荷下，踏车速率与Ｖ·Ｏ２间存在抛物线样相关关系。最佳代谢踏车速率随运动负荷的增加而增加。自选踏车率与运动负荷及最佳代谢踏车速率间无明确关系。
In four different test days, ten non-athlete healthy men were randomized to do extreme stress tests at 40, 60, 80 and 100 r / min. The results showed that the treadmill speed was parabola-like binomial correlation with V · O2 at exercise loads of 45, 90, 135, 180 and 225W, respectively. From 45 W, r were 0.93, 0.91, 0.89, 0.92 and 0.91, respectively (all P <0.01). Under different exercise loads, the optimal metabolic treadmill speed was 51.3, 54.6, 58.3, 72.3 and 80.4 rpm, respectively, and was highly linearly correlated with exercise load (r = 0.93, P < 0.01). The treadmill speed of the 10 subjects was 84 ± 6.58,83 ± 5.87,92 ± 5.17,80 ± 7.45 and 83 ± 9.7 r / min at different exercise loads, respectively There was no correlation between the optimal metabolic rate and exercise load (r = -0.17 and -0.32, all P> 0.05). The results suggest that there is a parabolic correlation between the car speed and V · O2 under the same exercise load. The optimal metabolic rate of treadmill increased with exercise load. There is no clear relationship between optional cycling rate and exercise load and the best metabolic rate of treadmill.
