The purpose of the present study was to determine the nutritional inta
ke of 11 skippers during the four stages of a solitary long-distance o
ffshore race. Body weight significantly decreased during the race (-1.
31 +/- 0.32 kg, range 3.5 to 0.1 kg, p <.01). Total daily energy intak
e was 18.53 +/- 0.71 MJ . day(-1) during the race, and it correlated n
egatively with the race duration of each leg. Energy intake during the
race was similar to 19% greater than that determined for a subgroup o
f 5 sailors during a control period 2 months after the race. Nutrient
intake expressed as percentage calories of total energy was estimated
at 50%, 35%, and 15% for carbohydrate, fat, and protein, respectively.
Voluntary fluid intake decreased with increasing race duration (p <.0
01). Despite high energy intakes, sailors lost body weight during the
solitary offshore race. It was not possible to conclude that this chan
ge in body weight was related to fluid loss and/or a discrepancy betwe
en energy intake and energy expenditure.
