Abstract
The physiological characteristics of 10 male elite sport parachutists (31.6 .+-. 3.69 years of age) were determined and compared to 10 male non-sport parachutist controls (30.2 .+-. 4.31 years) and other selected elite athletes. The typical sport parachutist was a highly educated (16.4 + 2.41 years), first born (9 out of 10), and, more often than not, single individual. During their mean 10.8 years of sport parachuting, these individuals made an average total number of 1,950 jumps (range 980 to 3,100) with a mean of 237.5 jumps during each of the last three years. Mean total free fall time was 22 h and 40 min. Compared to the non-sport parachutist control group, the elite sport parachutists were significantly higher (p < 0.05) in aerobic power (47.4 .+-. 9.04 vs. 37.2 .+-. 4.67 ml .cntdot. kg-1 .cntdot. min-1), vital capacity (5.27 .+-. 0.49 vs. 5.05 .+-. 0.31 L), maximum heart rate (203.2 .+-. 9.2 vs. 190.1 .+-. 7.4 bpm), and back hyperextension flexibility (21.12 .+-. 4.1 vs. 18.41 .+-. 2.4 in). The elite sport parachutist were also significantly lower (p < 0.05) in relative (%) body fat when compared to the control group (15.7 .+-. 4.51 vs. 20.1 .+-. 2.12%). The two groups were not significantly different (p > 0.05) with respect to resting heart rate, absolute body weight, dominant hand-grip strength, or lower back/hamstring flexibility as measured by the sit-and-reach test. Regarding somatotype, the elite sport parachutist can be classified as a balanced mesomorph. Compared to other selected elite athletes, the sport parachutists were lower in aerobic power and higher in relative body fat, yet with a summation of triceps, suprailiac, and abdominal skinfolds in the acceptable range for male athletes. The elite parachutists were approximately mid-range in absolute body weight and lower back/hamstring flexibility when compared to other selected elite athletes. Based on the findings of this study, there is evidence to suggest that some form of regular aerobic exercise along with a stretching and flexibility program is advisable for those individuals considering frequent participation and desiring peak performance in sport parachuting.
