This study monitored a paraplegic athlete in a handbike marathon, revealing high metabolic intensity and physiological variability during competition. Training recommendations suggest focusing on long-duration, low-intensity exercise for improved aerobic capacity.

Area of Science:

  • Sports Medicine
  • Exercise Physiology
  • Paralympic Sports

Background:

  • Investigating the physiological responses of paraplegic athletes in competitive handbiking is crucial for understanding their performance.
  • This case study examines the metabolic, pulmonary, cardiovascular, and energetic reactions during a city marathon.

Observation:

  • A 27-year-old male athlete with a complete T4 spinal cord injury competed in the Cologne Marathon using a custom-equipped handbike.
  • Physiological data including oxygen uptake, heart rate, energy expenditure, and blood lactate levels were recorded throughout the race.

Findings:

  • The athlete achieved a marathon time of 1:48:54.
  • Mean oxygen uptake was 1580 ml/min (max 2535 ml/min), mean heart rate was 137 bpm (max 157 bpm), and mean energy consumption was 463 kcal/h (max 758 kcal/h).

  • Blood lactate levels showed variability, with a pre-race value of 2.9 mmol/l and a peak of 4.4 mmol/l after 10 km.

    • Implications:

    • Paraplegic athletes exhibit high metabolic intensities and significant physiological variability during competition.
    • Training recommendations for competition handbikers include emphasizing long-duration, low-intensity exercise to enhance aerobic capacity, similar to marathon runners or cyclists.
