Experiment 2: Skeletal Muscle ABSTRACT Frog skeletal muscle is used as an animal model to study muscle contraction. The objectives of this experiment is to demonstrate the physiological responses of skeletal muscle to electrical stimuli using frog gastrocnemius‚ to understand twitch‚ summation‚ tetanus and fatigue‚ to investigate the relationship between initial tension and force of contraction‚ to explore the differences between human and frog skeletal muscle. The threshold voltage is 0.4V. The

Effects Of Exercise in Differents Body Systems Cardiorespiratory System - The vital capacity of the lungs can be increased though regular aerobic exercise. This makes the oxygen exchange system more efficient (Pangrazi‚ et al. 1997. p.322). Circulatory System - Heart rate‚ stroke volume‚ cardiac output‚ and blood pressure increase significantly during resistance exercise. The blood pressure response increases nonlinearly with the magnitude of active muscle mass and is higher during the eccentric
