What type of training is characterized by the contraction of muscles against a load that resists movement?

Resistance training is characterized by the contraction of muscles against a load that resists movement. This type of training aims to improve muscular strength, power, and endurance by using weights, resistance bands, or body weight to create resistance during exercises. When muscles contract against this load, it leads to micro-tears in the muscle fibers, which then repair and grow stronger during recovery. This process not only enhances muscle size and strength but also increases bone density and metabolic rate.

Endurance training primarily focuses on improving cardiovascular fitness and stamina over extended periods, typically involving activities like running or cycling at a moderate intensity without significant resistance. Aerobic training is similar, emphasizing sustained and rhythmic activities that rely on oxygen for energy. High-intensity interval training involves short bursts of intense exercise followed by rest or lower intensity, but it does not specifically emphasize the load-bearing aspect of muscle contraction like resistance training does.
