It is well known that Maximal Voluntary Ventilation (MVV) is closely related to maximal oxygen uptake, which is an index of systemic endurance capacity. In order to determine what other types of muscle activity are correlated with MVV, we measured quadriceps muscle strength as static muscle strength and upper body raising as dynamic muscle strength in 172 male and female subjects. The results showed a correlation with upper body raising, which is an index of endurance.
