Complementary and Alternative Medicine: Fair, Balanced, and to the Point
  • About this web log

    This blog is intended as an objective and dispassionate source of information on the latest CAM research. Since my background is in pharmacy and allopathic medicine, I view all CAM as advancing through the development pipeline to eventually become integrated into mainstream medical practice. Some will succeed while others fail. But all are treated fairly here.

    Rest periods and resistance exercise performance

    Researchers at The University of Tulsa in Oklahoma compared different forms of very short rest periods on subsequent performance.

    First, the details.

    • 30 volunteers performed 3 workouts:
      • 45 degrees leg press
      • Prone leg curl
      • Seated shoulder press
      • Standing barbell curl
    • The number of sets and the resistance employed were identical.
    • For each workout, they received one of the following treatments between sets:
      • 1 minute of rest as they stood upright
      • 30 seconds of rest as they stood upright, or
      • 30 seconds of concurrent massage and body part elevation (MBPE): massage of the exercised limbs in a raised and supported position
    • The volunteers performed as many repetitions as possible for each set.

    And, the results.

    • For each exercise, statistical analysis revealed the following total work/elapsed time results: 1 minute rest less than 30 seconds rest, 30 seconds’ MBPE.
    • For each exercise, cumulative repetition results were as follows: 1 minute rest greater than 30 seconds’ rest, 30 seconds MBPE.

    The bottom line?
    The authors observed, “rest period duration exerts more influence on resistance exercise performance than MBPE.”

    They recommend, “Those who seek improved resistance exercise performance should pay particular attention to rest period durations.”
