Resistance training “works” in older adults. But are the benefits less in the "oldest old" (85+)? After 12 weeks of whole-body resistance training, older adults aged 85+ had similar gains in muscle size, strength, and functional performance to those aged 65-75 years. It’s never too late to get started. pubmed.ncbi.nlm.nih.gov/3787…

“Designing minimal-dose programs that address barriers of time, complexity, and access to equipment is often not enough to change behaviour.” Despite the many benefits, engagement in resistance training remains low. Great article from @mackinprof, @JasminKMa and @EricRawsonPhD highlighting that in addition to making resistance training more feasible, there is a need to: - Incorporate behaviour change strategies to support long-term participation - Emphasise the short-term emotional benefits as well as longer-term health benefits journals.lww.com/acsm-health…

Strength training can boost aerobic fitness in older adults. Meta-analysis of 37 studies suggests short-term resistance training (24 weeks or less) improves: - Cardiorespiratory fitness (VO2peak): +1.89 ml/kg/min - Anaerobic threshold: +1.27 ml/kg/min - 6-minute walk test: +30.89 m More evidence strength training offsets declines in multiple body systems with ageing. academic.oup.com/ageing/arti…

How does 20+ years of exercise influence fitness and body composition in older adults? Compared to sedentary counterparts: - Aerobic fitness (VO2max):➕11.36 mL/kg/min - Percent body fat:➖5.41% - Fat-free mass:➖2.03 kg (no clear difference) - Strength (knee extensors):➕0.67 Nm/kg,➕49 Nm pubmed.ncbi.nlm.nih.gov/3762…

How much exercise can reduce the risk of cardiovascular events in adults (50+) with hypertension? - As little as 1 session of vigorous physical activity per month - Just 15 min moderate physical activity per day pubmed.ncbi.nlm.nih.gov/3757…
