Whole body sweat rate

Cardiorespiratory fitness increases whole body sweat rate in humans (11 g·m−2·h−1 [2, 19] per 10 mL·kg−1·min−1).

“Higher cardiorespiratory fitness improved whole body sweat rate (per 10 mL·kg−1·min−1: 11 g·m−2·h−1 [2, 19], P = 0.01)”

Age decreases whole body sweat rate in humans (-6 g·m−2·h−1 [-10, -1] per decade).

“and reduced whole body sweating (per decade: -6 g·m−2·h−1 [-10, -1], P < 0.01).”
