Final answer:
Detraining leads to physiological changes such as loss of muscle mass and strength, rise in non-protein nitrogen and body temperature, increased pulse rate, cardiovascular changes, skin alterations, and overall decrease in physical and cognitive abilities.
Step-by-step explanation:
Physiological Changes Due to Detraining
When a person stops exercising regularly, the body undergoes several physiological changes known as deconditioning or detraining. In addition to the loss of skeletal muscle mass and strength, typical manifestations of detraining include a rise in non-protein nitrogen in the blood, an increase in plasma protein concentration and chloride, and an increase in body temperature linked to a reduction in circulating fluid. This reduction in fluid also contributes to an increased pulse rate and reduced cardiac output.
Further changes associated with detraining consist of alterations in the skin, which may become dry, wrinkled, and loose, and a potential risk of exhaustion and collapse due to the decline in the body's physical adaptation to regular exercise. Cardiovascular endurance is also compromised, indicated by decreased firing rates of baroreceptors, leading to a falling blood volume and pressure.
Without regular physical activity, adaptation mechanisms fail to operate efficiently, and health can suffer. This maladjustment is evident in individuals who abruptly deviate from their usual physical exercise patterns, resulting in a decrease of overall physical and cognitive abilities.
