Effect of Climbing Speed on Pulmonary Oxygen Uptake and Muscle Oxygen Saturation Dynamics in the Finger Flexors
Original language description
Purpose: Although sport climbing is a self-paced whole-body activity, speed varies with climbing style, and the effect of this on systemic and localized oxygen responses is not well understood. Therefore, the aim of the present study was to determine muscle and pulmonary oxygen responses during submaximal climbing at differing speeds of ascent. Methods: Thirty-two intermediate and advanced sport climbers completed three 4-minute-long ascents of the same route at 4, 6, and 9 m center dot min-1 on a motorized climbing ergometer (treadwall) on separate laboratory visits. Gas analysis and near-infrared spectroscopy were used to determine systemic oxygen uptake ( VO2) and muscle oxygen saturation (StO2) of the flexor digitorum profundus. Results: Increases in ascent speed of 1 m center dot min-1 led to increases of VO2 by 2.4 mL center dot kg-1 center dot min-1 (95% CI, 2.1 to 2.8 mL center dot kg-1 center dot min-1) and decreases in StO2 by -1.3% (95% CI, 1.9% to -0.7%). There was a significant interaction of climbing ability and speed for StO2 (P < .001, eta 2p = .224). The results revealed that the decrease of StO2 was present for intermediate but not advanced climbers. Conclusions: In this study, the results suggest that VO2 demand during climbing was largely determined by climbing speed; however, the ability level of the climber appeared to mitigate StO2 at a cellular level. Coaches and instructors may prescribe climbing ascents with elevated speed to improve generalized cardiorespiratory fitness. To stimulate localized aerobic capacity, however, climbers should perhaps increase the intensity of training ascents through the manipulation of wall angle or reduction of hold size.
