Metabolic and contractile differentiation of rabbit muscles during growth.
1. A study was carried out of post-natal evolution of the oxidative, glycolytic and contractile capacities in various types of rabbit muscle. 2. At birth, muscles are non-differentiated and present very limited metabolic and contractile activity, metabolism is mainly oxidative in all muscles. 3. Although muscular discrimination is manifest from the sixth week after birth, the glycolytic metabolism reaches its maximum capacity only after six to eight weeks. 4. Subsequently, oxidative metabolic capacity steadily decreases until adulthood.
