Document Summary

Increases: muscular strength, muscular endurance, stamina, flexibility, speed and power, blood volume and hemoglobin. Decreases: body fat, stress and tension, resting heart rate. Helps to: prevent injuries, rehabilitate injuries, improve cardio-respiratory function, alter metabolism to improve caloric utilization, facilitate quicker recovery from workouts and competitions. Increased risk of: muscle and tendon injuries, bone and ligament injuries, low back injuries, contact with weight plates causing injury (more likely free weights, large transient increases in systolic blood pressure (sbp, excessive fatigue due to over training. Muscular strength: the greatest amount of force that a muscle or muscle group can produce in a single maximal effort. Muscular endurance: the ability of a muscle group to perform repeated contractions against a light load for an extended period of time. Muscular power: the ability to produce force quickly, force * distance. Isometric contraction: no change in length of muscle (stretches,planks, muscular contraction with no change in length of the muscle, disadvantage.
