According to the article ‘The coming age of resistance exercise as a primary form of exercise for health’, what is the relationship between aerobic exercise (AE) and resistance exercise (RE) in terms of mortality risk reduction?

Question

BlackTom AI · Accepted Answer

Both aerobic exercise (AE) and resistance exercise (RE) confer comparable reductions in all‑cause mortality, as the article reports that their effects on lowering mortality risk are similar.

1. Relevant knowledge points and concepts
- Aerobic exercise (AE): continuous, rhythmic activities that improve cardiovascular endurance (e.g., running, cycling).
- Resistance exercise (RE): activities that increase muscular strength and mass (e.g., weight training).
- Mortality risk reduction is typically reported as relative risk or hazard ratio reductions in large observational cohorts and meta-analyses.
- Mechanisms linking exercise to lower mortality include improved cardiorespiratory fitness, better metabolic health, lower blood pressure, improved lipid profiles, and greater muscle mass/strength.

2. Step‑by‑step reasoning
- The article reviews epidemiological and interventional evidence comparing AE and RE.
- It notes both AE and RE are independently associated with lower all‑cause and cardiovascular mortality in cohort studies.
- When effect sizes from studies are compared, AE and RE show similar magnitudes of risk reduction after adjusting for confounders.
- The article therefore concludes that RE should be considered on par with AE for mortality benefit, supporting RE as a primary exercise modality for health.

3. Calculations/intermediate steps
- No numerical calculation is required here; the conclusion is based on synthesis of reported relative risk reductions and adjusted associations across studies, which the article summarizes as being of similar magnitude for AE and RE.

4. Why the correct answer is correct
- Because the article synthesizes evidence showing both exercise types independently reduce mortality by similar proportions and emphasizes that RE’s benefits are comparable to AE’s for lowering mortality risk.

5. Why the other options are incorrect
- “AE is more effective than RE” and “RE is more effective than AE” claim superiority not supported by the article’s synthesis.
- “AE and RE have no impact on mortality risk” contradicts extensive evidence showing both reduce mortality.

6. Conclusion
- The correct answer is: AE and RE have similar effects on lowering mortality risk, which matches the provided answer.
