Beta blocking medication does not affect self-selected walking pace. This simple test, measuring walking speed perception, remains reliable for assessing fitness even with beta blockers.

Area of Science:

  • Exercise Physiology
  • Clinical Pharmacology

Background:

  • The self-selected walking pace test is a valid measure of cardiorespiratory fitness, correlating with maximal oxygen uptake.
  • Beta-blocking medications are known to cause fatigue, potentially impacting exercise performance and physiological tests.

Purpose of the Study:

  • To investigate the effect of beta blockade on the self-selected walking pace test.
  • To determine if oxprenolol, a beta blocker, alters walking speed or stride length during this test.

Main Methods:

  • Twenty-three healthy men completed the self-selected walking pace test (slow, normal, fast) both on and off 80 mg daily oxprenolol.
  • Heart rate, walking speed, and stride length were measured during the test.

Main Results:

  • Oxprenolol significantly reduced heart rate but did not significantly alter walking speed at any self-selected pace.
  • Stride length remained unchanged between the on- and off-medication conditions.

Conclusions:

  • Beta blocking medication, specifically oxprenolol, does not interfere with the self-selected walking pace test.
  • The test remains a reliable and safe method for assessing walking speed perception and cardiorespiratory fitness in individuals taking beta blockers.
