To evaluate whether upper-body compression affects power output and selected metabolic, cardiorespiratory, hemodynamic, and perceptual responses during three 3-min sessions of double-poling (DP) sprint.
Ten well-trained male athletes (25 ± 4 y, 180 ± 4 cm, 74.6 ± 3.2 kg) performed such sprints on a DP ski ergometer with and without a long-sleeved compression garment.
Mean power output was not affected by such compression (216 ± 25 W in both cases; P = 1.00, effect size [ES] = 0.00), although blood lactate concentration was lowered (P < .05, ES = 0.50–1.02). Blood gases (ES = 0.07–0.50), oxygen uptake (ES = 0.04–0.28), production of carbon dioxide (ES = 0.01–0.46), heart rate (ES = 0.00–0.21), stroke volume (ES = 0.33–0.81), and cardiac output (ES = 0.20–0.91) were also all unaffected by upper-body compression (best P = 1.00). This was also the case for changes in the tissue saturation index (ES = 0.45–1.17) and total blood content of hemoglobin (ES = 0.09–0.85), as well as ratings of perceived exertion (ES = 0.15–0.88; best P = .96).
The authors conclude that the performance of well-trained athletes during 3 × 3-min DP sprints will not be enhanced by upper-body compression.
