Final answer:
The second transition period after exercise is called active recovery, and it involves low-intensity exercise to aid in physiological recuperation.
Step-by-step explanation:
The second transition period in the context of physiological recovery after exercise is called active recovery. Active recovery involves performing low-intensity exercise following a period of intense physical activity. This process helps to clear metabolic waste from muscles and reduce lactic acid buildup, thereby improving overall muscle recovery. It is distinct from passive rest or passive recovery, where an individual remains mostly inactive after exercise.
Active recovery could also be applied to sleep phases, particularly in the initial NREM Stages of Sleep, where the body transitions from wakefulness to sleep. However, in terms of exercise and physiological recovery, active recovery is the term that best describes the period of low-intensity activity that helps with recuperation.
