The effect of mucle fibre type on eccentric exercise damage.

Rationale

• During treadmill running, only postural motor units will be active, possibly explaining damage to slow muscles.
• Damage has been shown to depend strongly on sarcomere length range.

Talbot, J. A. and D. L. Morgan. The effects of stretch parameters on eccentric exercise induced damage to toad skeletal muscle. J. Musc. Res. Cell. Mot. 19: 237-245, 1998. (Eight toad sartorii, 60 contractions with 10% stretch at 3L₀/s.)

• Different fibre types within the muscle may be operating over different sarcomere length ranges for the same muscle length range.
