Standing during cycling may increase overall muscular activity. However, effects of standing vs. seated posture on performance measures during repeated bouts have not been extensively explored.
The purpose of this study was to examine the effects of standing vs. seated posture on repeated Wingate performance. Healthy volunteers (n = 35) performed 3 consecutive Wingate anaerobic power tests (W1, W2, W3) in a standing (STA) as well as seated (SIT) posture. Within-group comparisons were made for peak power, mean power, minimum power, and fatigue index. Results were considered significant at p <= 0.05. No significant differences were found for peak power in W1, W2, orW3. No significant difference was found for mean power in W1 or W2, but significant differences were found for mean power in W3 (STA: 451.5 +- 105.3, SIT: 425.7 +- 110.0); minimum power in W1 (STA: 433.6 +- 100.8, SIT: 381.5 +- 96.9), W2 (STA: 348.1 +- 112.9, SIT: 308.0 +- 95.8), W3 (STA: 292.0 +- 103.6, SIT: 265.3 +- 90.8); and fatigue index: W1 (STA: 51.3 +- 10.7, SIT: 56.9 +- 9.3), W2 (STA: 56.5 +- 12.6, SIT: 61.8 +- 12.2), W3 (STA: 59.4 +- 13.1, SIT: 63.6 +- 12.4).
Results suggest that a standing posture enhances performance during repeated Wingate cycling. The enhancement is most likely due to an attenuated loss in power, which in turn improves fatigue index.
