    Weight-trainers show significantly greater isokinetic strength and limb girth compared to untrained individuals. This enhancement was observed across various muscle groups and velocities, with upper limbs showing a relatively greater increase.

    Area of Science:

    • Sports Science
    • Biomechanics
    • Human Physiology

    Background:

    • Weight training significantly impacts muscular strength and hypertrophy.
    • Understanding differential adaptations in upper versus lower limbs is crucial for training optimization.

    Purpose of the Study:

    • To compare isokinetic strength and limb girth between weight-trainers (powerlifters, bodybuilders) and untrained men.
    • To investigate the relationship between low and high-velocity strength.
    • To analyze the relative strength and mass enhancements in upper versus lower limbs.

    Main Methods:

    • Isokinetic dynamometry was used to measure ankle plantarflexion (APF), knee extension (KE), and elbow extension (EE) strength.
    • Limb girth measurements (calf, thigh, arm) were recorded.

  • Participants included 13 weight-trainers and 25 untrained men.

    • Main Results:

    • Weight-trainers exhibited significantly greater strength in APF (21%), KE (25%), and EE (73%) compared to controls.
    • Weight-trainers also showed increased limb girth: calf (6%), thigh (13%), and arm (31%).
    • Strength was enhanced at both low and high velocities, with a strong correlation (r=0.84) between them. Powerlifters had greater low-velocity APF strength than bodybuilders.

    Conclusions:

    • Weight training leads to substantial strength and muscle mass gains across multiple muscle groups.
    • Upper limb strength and mass show relatively greater enhancement compared to lower limbs in weight-trainers.
    • Training habits and muscle group trainability may explain the observed differential adaptations.
