Oxygen uptake before and after strenuous exercise for about one minute was determined in 5 healthy male subjects at comfortable (18°C db) and hot (35°C db) room temprature. It was assumed that the oxygen uptake during recovery could be fitted best by an equation of the form, Y = c + a1 exp (- k1 t) + a2 exp (-k2 t), where Y is the oxygen uptake during recovery at any time (t). The term a1 exp (- k1 t) and a2, exp (- k2 t) presumably represent the alactic and lactic components, the amount of alactic and lactic oxygen debt is equal to a1/K1 and a2/k2. In this study the each constant in above equation was determined by the least squares method. It was found that there are no statistical difference between 18°C and 35°C in not only exponential curve parameters, but also alactic, lactic and total oxygen debts, while total oxygen debt at 35°C was higher in 3 out of 5 subjects.
Ikegami et al. (Sat,) studied this question.
