Final answer:
The ACE Integrated Fitness Training Model partitions cardiorespiratory training into aerobic and anaerobic exercise. Aerobic exercise involves sustained low to moderate-intensity activities while anaerobic exercise involves short, high-intensity bursts. Both contribute to overall cardiorespiratory fitness.
Step-by-step explanation:
Under the ACE Integrated Fitness Training Model, the phases of cardiorespiratory training involve various levels of intensity. Predominantly, it includes aerobic and anaerobic exercises. Aerobic exercises involve low to moderate intensity activities that demand energy primarily through the aerobic metabolism. Some examples include swimming, cycling, and brisk walking. This form of training typically involves a high percentage of slow-twitch muscle fibers that consume large amounts of oxygen, improving cardiovascular endurance.
On the other hand, anaerobic exercise includes shorter bursts of high-intensity physical activity. Anaerobic refers to a state where sufficient oxygen is not available for energy demands, forcing the body to use stored energy sources. Both aerobic and anaerobic exercises are essential in establishing overall cardiorespiratory fitness, each targeting different aspects of this fitness component.
