Physiological Evaluation of Professional Water-Skiers

Abstract

This study evaluated the physiological profile of water-skiers. Six male and four female elite professional water-skiers were selected based on their current world rankings. Body composition, aerobic power, and strength of the upper body, lumbar, and leg muscles were measured. O₂max was higher and percent fat was lower than values reported for nonathletes, but similar to those of elite speed skaters, soccer players, and football backs. Six male and four female age and weight matched untrained controls were recruited to compare chest press and upper back strength. Skiers and controls did not differ in bench press strength. However, upper back strength was greater for water-skiers. The ratio of upper back to bench press strength was greater for the skiers, probably due to the pull movement required for the sport. Isometric lumbar extension strength was higher than average, especially for the male skiers in the extended range of motion. In general these skiers were leaner, more aerobically fit, and stronger than values reported in the literature for the average population. The strength measurements appear to indicate specific adaptations related to the sport of water-skiing.
