Dynamic exercises involve concentric and eccentric contractions. For example, when you perform a biceps curl, the action of curling the weight up is the concentric motion. Concentric contractions occur as a muscle shortens and generates force against a load to move it.
Once innervated, the protein filaments within each skeletal muscle fiber slide past each other to produce a contraction, which is explained by the sliding filament theory. The contractions that is produced can be described as a twitch, summation, or tetanus, depending on the frequency of action potentials.uscle contractions can be described based on two variables: length and tension. A muscle contraction is described as isometric if the muscle tension changes but the muscle length remains the same. In contrast, a muscle contraction is isotonic if muscle length changes but the muscle tension remains the same.
