Summary

Comparing exercise protocols, uphill treadmill running and walking with handweights elicited similar peak physiological responses. These methods provide a maximal stimulus to the oxygen transport system, surpassing other handweight exercises.

Area of Science:

  • Exercise Physiology
  • Sports Science
  • Human Performance

Background:

  • Assessing exercise intensity is crucial for training prescription.
  • Handweighted exercise offers a variable modality for increasing physiological demand.
  • Treadmill-based protocols are common for standardized exercise testing.

Purpose of the Study:

  • To compare peak physiological responses across four distinct exercise protocols.
  • To evaluate the impact of varying handweight loads and treadmill grades on exercise intensity.
  • To determine which protocol provides the most significant stimulus to the oxygen transport system.

Main Methods:

  • Sixteen healthy males participated in the study.
  • Four protocols were tested: uphill running (UR), uphill walking with handweights (UWHW), walking with handweights (WHW), and stationary handweight pumping (SHW).

  • Peak oxygen uptake (VO2 peak), heart rate (HRpeak), ventilation (Ve peak), and respiratory exchange ratio (RERpeak) were measured.

    • Main Results:

    • No significant differences in peak physiological responses were found between UR and UWHW.
    • UR and UWHW elicited significantly higher responses (VO2 peak, HRpeak, Ve peak) than WHW and SHW (p < .01).
    • WHW showed higher VO2 peak and HRpeak compared to SHW, indicating a dose-response relationship with exercise intensity.

    Conclusions:

    • Uphill treadmill running and uphill walking with handweights are equally effective in maximizing peak physiological responses.
    • Incorporating handweights during uphill walking significantly enhances the cardiovascular and respiratory demands.
    • These findings suggest that combined treadmill exercise and handweight use can serve as a potent stimulus for improving oxygen transport capacity.
