Abstract

KOHRT, W. M., D. W. MORGAN, B. BATES, and J. S. SKINNER. Physiological responses of triathletes to maximal swimming, cycling, and running. Med. Sci. Sports Exerc., Vol. 19, No. 1, pp. 51–55, 1987. The objectives of this study were to: (a) develop a physiological profile for a group of trained triathletes and (b) determine whether multiple modes of training result in general or specific adaptations. V̇O2max of 13 trained triathletes (mean = 29.5 yr) was measured during treadmill running (TR), cycle ergometry (CE), and tethered swimming (TS) over a 6-wk period encompassing a half-triathlon (1.2 mile swim/56 mile bike/13.1 mile run). Most subjects performed two tests in each mode. Since test-retest reliability coefficients for TR, CE, and TS V̇O2max were 0.97, 0.93, and 0.97, respectively, results were averaged:
