Intensity plays a major role in many physical, physiological, psychological, and mental health benefits from physical activity participation and strength training is no different.
While the physical benefits of heavy loads are more obvious (i.e. lift heavier things, become stronger), other benefits vital to healthy ageing are often forgotten (i.e. rate of force development, power, neural adaptations).
Performing strength training with heavy loads is important, at all ages. Beyond the dose-response relationship between strength and health...
✔︎ Older adults with limited strength have to work at near maximal capacity just to get out of a chair, walk up the stairs, or push doors open. If you are training to match or exceed that intensity, you will be able to restore their strength quickly so their strength is no longer responsible for decreasing their independence and quality of life. If not, you may be helping to accelerate their decline.
✔︎ Ideally, we want people to start strength training from a young age to reap the benefits later in life. However, health is a ‘stock’ that requires consistent investments over time. Thus, health is quite costly in terms of time and resources we must devote to our health-enhancing behaviours (i.e. participating in strength training). Strength training consistently requires developing a powerful delayed gratification mindset (because skipping the gym to stay on the couch and watch TV feels so good right now). But most people today want instant gratification from their actions. This is where intensity can play a role. Intensity can help people see and feel that each and every strength training session is getting them closer to their goals (they see they are able to increase their weights, they leave with a positive accomplishment feeling...). On the other hand, sessions of low intensity and effort make end goals seem too far in the future, and what feels good now (skipping the gym) may seem like the more rewarding choice in the moment.
