What is emphasized as a potentially viable option to address type 2 diabetes (T2D) in the article ‘The coming age of resistance exercise as a primary form of exercise for health’?

Question

BlackTom AI · Accepted Answer

Combined aerobic plus resistance training produces additive benefits for glucose regulation and is therefore emphasized as a potentially viable option to address type 2 diabetes (T2D).

1) Relevant knowledge points and concepts
- Aerobic (endurance) exercise improves cardiorespiratory fitness, insulin sensitivity, and whole-body glucose uptake.
- Resistance (strength) exercise increases skeletal muscle mass, enhances GLUT4 expression and insulin-mediated glucose disposal, and improves resting metabolic rate.
- T2D management benefits from interventions that both lower blood glucose and increase lean mass; combined training often targets both outcomes.

2) Step-by-step reasoning
- The article’s title promotes resistance exercise as a primary form, but it reviews evidence comparing exercise modes for T2D.
- Meta-analyses and clinical trials show that combining aerobic and resistance exercise yields larger reductions in HbA1c and fasting glucose than either mode alone.
- Mechanistically, aerobic activity increases acute glucose utilization and mitochondrial function, while resistance training increases muscle mass that serves as a long-term glucose sink. These mechanisms act together, producing an additive effect.

3) Calculations and intermediate steps
- No numeric calculation is required here; interpretation relies on comparative effect sizes reported in literature (e.g., combined training typically shows greater mean HbA1c reduction than single-mode programs).

4) Why the correct answer is correct
- A combination of aerobic and resistance exercise aligns with the article’s emphasis on harnessing both cardiorespiratory and muscular adaptations to control blood glucose more effectively than either alone. It is presented as a viable, evidence-based strategy for T2D prevention and management.

5) Why other options are incorrect
- Aerobic exercise alone: beneficial but less effective than combined programs for improving both HbA1c and body composition.
- Resistance exercise alone: improves muscle mass and insulin sensitivity but lacks the full cardiovascular benefits and glucose-lowering magnitude seen with combined training.
- Medication: important for many patients but the article focuses on exercise-based strategies; medication is not the emphasized “potentially viable” exercise option.

6) Conclusion
The correct answer is “A combination of aerobic and resistance exercise,” which matches the provided answer.
