Alcoholism causes minor muscle performance deficits in arms and legs, affecting strength and power. These functional impairments were less severe than anticipated in detoxified alcoholic men.

Area of Science:

  • Neurology
  • Sports Medicine
  • Physiology

Background:

  • Alcohol muscle dysfunction (myopathy) is documented histochemically and morphologically.
  • The functional impact of alcoholism on limb muscle strength and power remains under-investigated.

Purpose of the Study:

  • To assess the functional capabilities (strength, power) of arm and leg muscles in alcoholic men.
  • To quantify the relative impact of alcoholism on diverse muscle groups.

Main Methods:

  • Evaluated elbow, knee, and ankle flexor/extensor muscle strength in detoxified alcoholic men (N=83) and controls (N=61).
  • Utilized a computer-operated isokinetic dynamometer for strength, work, and power assessments.
  • Measured isometric torque and force-velocity relationships in knee extensors.

Main Results:

  • No significant differences in muscle mass (muscle-plus-bone cross-sectional area) between groups.
  • Alcoholics exhibited small deficits (3-8%) in isokinetic torque, work, and power for elbow, knee, and ankle muscles.
  • Alcoholics showed approximately 4-6% lower isometric torque and slightly slower contraction speeds (3.9-6.6%) in knee extensors.

Conclusions:

  • Observed muscle performance deficits were smaller than expected.
  • Factors contributing to smaller deficits include subject selection (no comorbidities/polydrug abuse), lifestyle-matched controls, and extended detoxification (35 days).
