Recording and evaluation of isotonic and isometric contractions of skeletal muscle in situ.
A procedure is described for obtaining records and identifying curves of isotonic and isometric contractions (both tetanic and twitch) of the gastrocnemius muscle of the rabbit in situ. The experimental conditions have made it possible to follow the above mentioned phenomena and to measure further parameters in series at sequentially altered muscle lengths and loads acting in the course of isotonic contractions.
