The Effects of Exercise: Clinical Study on Men Aged 20-30 Years

Effects of Exercise on Men Aged 20-30 Years

a) Blood pressure

b) Respiratory rate

c) Body temperature

d) Oxygen saturation

Question:

Compared with the measurement before the session, which of the following is most likely to be decreased after a 15-minute session on a treadmill?

Final answer:

Oxygen saturation is most likely to decrease after a 15-minute session on a treadmill during a clinical study, given the increased oxygen consumption during exercise.

Explanation:

During a clinical study examining the effects of exercise on men between the ages of 20 and 30 years, the question asks which measurement is most likely to be decreased after a 15-minute session on a treadmill. Based on our understanding of the physiological responses to exercise, we know that during exercise, cardiovascular parameters such as heart rate and blood pressure increase to accommodate the heightened demand for oxygen and nutrient supply to tissues. Conversely, oxygen saturation (the measure of the amount of oxygen bound to hemoglobin in the blood) is the variable most likely to decrease compared to pre-exercise levels as the body uses up more oxygen during the strenuous activity.
