The largest study to compare the mortality outcomes of different types of exercise found people who did strength-based exercise had a 23 percent reduction in risk of premature death by any means, and a 31 percent reduction in cancer-related death. Lead author Emmanuel Stamatakis from the School of Public Health and the Charles Perkins Centre said while strength training has been given some attention for functional benefits as we age, little research has looked at its impact on mortality. “The study shows exercise that promotes muscular strength may be just as important for health as aerobic activities like jogging or cycling,” said Associate Professor Stamatakis. “And assuming our findings reflect cause and effect relationships, it may be even more vital when it comes to reducing risk of death from cancer.” The World Health Organization’s Physical Activity Guidelines for adults recommend 150 minutes of aerobic activity, plus two days of muscle strengthening activities each week. Summary of key findings:
- participation in any strength-promoting exercise was associated with a 23 percent reduction in all-cause mortality and a 31 percent reduction in cancer mortality
- own bodyweight exercises that can be performed in any setting without equipment yielded comparable results to gym-based activities
- adherence to WHO’s strength-promoting exercise guideline alone was associated with reduced risk of cancer-related death, but adherence to the WHO’s aerobic physical activity guideline alone was not
- adherence to WHO’s strength-promoting exercise and aerobic guidelines combined was associated with a greater risk reduction in mortality than aerobic physical activity alone
- there was no evidence of an association between strength-promoting exercise and cardiovascular disease mortality.
