Which of the following is not a health benefit of cardiorespiratory training?

Question

BlackTom AI · Accepted Answer

Cardiorespiratory exercise typically raises high-density lipoprotein (HDL) — the “good” cholesterol — rather than decreasing it, so a decrease in HDL is not a health benefit of this training.

1) Relevant knowledge points and concepts
- Cardiorespiratory (aerobic) training improves cardiovascular and metabolic health: it generally increases HDL, lowers LDL and triglycerides, improves blood pressure and insulin sensitivity, and enhances oxygen delivery and endurance.
- Exercise also supports bone health (reduces osteoporosis risk), improves mental health (reduces anxiety), and reduces perceived fatigue by increasing mitochondrial efficiency and aerobic capacity.

2) Step-by-step reasoning
- Option a: “Decreased HDL” — HDL protects against atherosclerosis; aerobic training tends to increase HDL. Therefore a decrease in HDL would be harmful, not a benefit.
- Option b: “Decreased rate of osteoporosis” — Regular weight-bearing and aerobic activities stimulate bone remodeling and help preserve bone mass, lowering osteoporosis risk. This is a recognized benefit.
- Option c: “Decreased anxiety” — Aerobic exercise releases endorphins, reduces stress hormones, and improves mood and sleep, which reduces anxiety. This is supported by many studies.
- Option d: “Decreased fatigue” — Improved cardiorespiratory fitness increases energy efficiency and lowers fatigue in daily tasks and chronic fatigue conditions; many people report less fatigue with regular aerobic training.

3) Calculations / intermediate steps
- No numeric calculations are required; the conclusion is based on physiological effects of exercise.

4) Why the correct answer is correct
- Because cardiorespiratory training increases HDL (not decreases it), “Decreased HDL” contradicts the known physiological benefits. Thus it is not a health benefit.

5) Why the other options are incorrect choices for “not a benefit”
- b, c, and d describe well-established benefits of regular cardiorespiratory exercise (reduced osteoporosis risk, reduced anxiety, reduced fatigue), so they are true benefits and therefore not the correct answer to “which is not a benefit.”

Conclusion: The correct choice is a. Decreased HDL, which matches the provided answer.
