Caries research·2007

This study measured maximum voluntary contraction in healthy adults using hand-held dynamometry. Results provide reference values for muscle strength, noting females have about two-thirds the strength of males.

Area of Science:

  • Physiology
  • Biomechanics
  • Kinesiology

Background:

  • Assessing maximal voluntary contraction (MVC) is crucial for understanding muscle function.
  • Establishing reliable reference values for muscle strength is essential for clinical and research applications.
  • Hand-held dynamometry offers a practical method for measuring muscle strength across various populations.

Purpose of the Study:

  • To determine reference values for maximum voluntary contraction (MVC) in major muscle groups of healthy adults.
  • To evaluate the reliability and variability of MVC measurements using hand-held dynamometry.
  • To investigate the influence of age, sex, and body composition on muscle strength.

Main Methods:

  • MVC was measured in 50 healthy females and 50 males (aged 20-60 years) across thirteen major muscle groups.

  • Measurements were taken using a hand-held dynamometer.
  • Intrasession, left-right, and test-retest (one-week interval) variations were calculated, along with 95% reference limits.

    • Main Results:

    • Intrasession and left-right strength variations showed ratios generally between 0.82 and 1.22.
    • Test-retest reliability (one-week interval) yielded ratios between 0.82 and 1.23.
    • Female muscle strength averaged approximately two-thirds that of males, with some age and weight/Quetelet Index correlations observed.

    Conclusions:

    • Hand-held dynamometry provides reliable reference values for muscle strength assessment.
    • Sex is a significant determinant of muscle strength, with males exhibiting greater strength than females.
    • The established reference ranges can aid in the interpretation of muscle strength data in clinical and research settings.
