  • Strength training should consist of isotonic exercises, as this promotes joint mobility.
  • isometric and isotonic

Examples

  • The EMG signal is segmenting into shorter epochs (e.g., 0.5 s - 1 s) where, for static isotonic contractions, the processes may be considered stationary.

    Academic text (1997)
  • The maximum possible velocity of 100 degrees/s of the dynamometer diminished the non-isokinetic portions of the isotonic exertions, thereby eliminating their usefulness.

    Academic text (1997)
  • Three modes of strength testing were used: isometric, isokinetic, and isotonic (4, 26).

    Academic text (1997)
  • The isotonic mode simulated by the dynamometer can best be called isoresistive: the dynamometer provides the resistance set by the experimenter.

    Academic text (1997)
  • These measurements were taken from isometric length-tension, isotonic load-excursion, and force-velocity relationships found for the cineplastized muscle of each subject (25).

    Academic text (2001)
  • The trials were randomized for the isometric, isokinetic, and isotonic modes of exertion to minimize unintended fatigue and order effects.

    Academic text (1997)
  • LeFort et al. provided a combination of water-based aerobic exercises with isotonic loading for all major muscle groups, including the trunk flexors and extensors, for 8 weeks.

    Academic text (1997)
  • Burkhead and Rockwood (1992) suggested a specific muscle-strengthening exercise program for the treatment of shoulder instability that consisted of isotonic rotator cuff strengthening.

    Academic text (2003)
  • Many athletes incorporate isotonic exercises into their training regimens to improve muscle strength while maintaining joint flexibility.

  • Physical therapists often recommend isotonic exercises for rehabilitation, as they help strengthen muscles without risking injury.

Morphology

isotonic = tonic (semi-transparent) = iso + ton + ic

The prefix 'iso-' means equal, and 'tonic' relates to tone, but understanding the specific application to muscular contraction requires specialized knowledge.

Etymology

Isotonic comes from Greek parts iso- meaning 'equal' and tonos meaning 'tone' or 'tension', a sense you find in the word tone. So an isotonic muscle contraction keeps a steady 'tone' while the muscle shortens or lengthens, which is what happens when you lift a weight.
