Competitive speed skating's low position increases heart rate and blood lactate. This study shows reduced oxygen delivery to muscles in this position, impacting athlete performance and potentially leading to injury.

Area of Science:

  • Exercise Physiology
  • Sports Biomechanics
  • Skeletal Muscle Physiology

Background:

  • The characteristic low
  • sitting
  • position in speed skating is associated with elevated heart rate and blood lactate compared to upright activities.

Purpose of the Study:

  • To investigate the physiological impact of the low skating position on muscle oxygenation and blood flow.

Main Methods:

  • Duel wavelength spectrophotometry measured muscle oxygenation (hemoglobin/myoglobin deoxygenation) in five muscle groups.
  • In-line skating in upright (US) and low (LS) positions was performed on a treadmill at two speeds (2.68 and 3.13 m.s-1) with a 4% grade.
  • Expired gas analysis, blood lactate (LA) concentrations, and joint angles were recorded.

Main Results:

  • For similar oxygen uptake, heart rate and LA were significantly higher in the LS position.
  • Muscle deoxygenation was significantly greater in the LS position compared to US, particularly at higher speeds.
  • Muscle deoxygenation correlated strongly with blood lactate levels (r > 0.95).

Conclusions:

  • The low speed skating position compromises blood flow and oxygen delivery to exercising muscles.
  • This reduced oxygen availability contributes to the observed increases in heart rate and blood lactate during intense skating efforts.
