Title: Physiological responses on standardized climbing task in sport climbers Purpose: To determine the effect of height, wall angle, climbing speed and climbing ability on physiological responses in sport climbers. Methods: The study was divided into three parts. 75 sport climbers (36 female and 39 male) completed differing tests on climbing wall and motorized climbing ergometer. Perceived exertion was assessed on a scale suggested by Borg. Indirect calorimetry, venous blood samples and near-infrared spectroscopy were used to assess physiological response, hormonal response and muscle oxygen saturation, respectively. Results: Perceived exertions were higher when climbing to height as opposes to climbing low to the ground on the treadwall (+5,3%; P = 0,013; ηp 2 = 0,149) (Study 1A). The physiological response was higher on the climbing wall as opposed to the treadwall: V̇ O2 (+6%; P = 0,03; ηp 2 = 0,22), SF (+4%; P = 0,04; ηp 2 = 0,20), V̇ E (+9%; P = 0,01; ηp 2 = 0,30) a EC (+16%; P < 0,001; ηp 2 = 0,48). There was an interaction for climbing ability and post- climbing catecholamine concentration (P < 0,01, ηp 2 = 0,28) (Study 1B). With increasing climbing speed greater differences were found for V̇ O2 (P < 0,001, ηp 2 = 0,923) than for StO2 (P < 0,001, ηp 2 = 0,448). Between-subject effect...
