Gender differences in substrate for endurance exercise.
The effects of gender on substrate utilization during prolonged submaximal exercise were studied in six males and six equally trained females. After 3 days on a controlled diet (so that theExpand

Effects of menstrual cycle on blood lactate, O2 delivery, and performance during exercise.
The effects of the menstrual cycle on cardiorespiratory variables, blood lactate, and performance were studied in exercising females. Nine healthy subjects, 20--24 yr of age, were investigated inExpand

Effect of pH on cardiorespiratory and metabolic responses to exercise.
Five male subjects performed exercise at 33, 66, and 95% of their maximum power output on three occasions in random order. Each study was preceded by a 3-h period in which capsules were taken byExpand

Effect of PH on muscle glycolysis during exercise.
1. Five males were studied on three occasions, after oral administration of CaCO3 (control), NH4Cl (acidosis) and NaHCO3 (alkalosis), in a dose of 0.3 g/kg, taken over a 3 h period at rest. TheExpand
