As we age, maintaining physical activity becomes more and more important, not just for mobility — but for overall health. Recent studies have shown why older adults often move slower and how regular exercise can slow down the natural decline in muscle efficiency.
One study from the University of Colorado Boulder found that older adults use more energy to move which makes them move slower. Dr. Alaa A. Ahmed, senior author of the study, explained to Medical News Today, “With age, our muscle cells may become less efficient in transforming energy into muscle force and ultimately movement… We recruit more muscles, which costs more energy, to perform the same tasks.”
Another May 2024 study from Stanford Medicine revealed that exercise significantly benefits brain health by improving cognition, mood and reducing the risk of neurodegenerative diseases. Researchers found positive impacts of exercise on overall health, including the immune system, energy production and metabolism.
How can aging Canadians incorporate exercise into their daily routines — and when should they start? Here’s what you need to know.
What seniors need to know about exercising
Steve Di Ciacca, a physical therapist and program manager at the Canadian Centre for Activity and Aging, told Yahoo Canada that regular exercise is key in mitigating the natural decline in muscle efficiency and movement.
“Our body is not meant to last forever. We kind of peak in our 30s and 40s, and then with the natural process, we start to lose muscle mass, we start to lose efficiency, we start to lose brain matter. But it’s not necessarily the same for everybody,” Di Ciacca said. “It is largely dependent on how we really live our lives going forward.” Leading a sedentary lifestyle can speed up this decline, making people more frail and dependent on others.
Incorporating regular exercise can slow down and even reverse some aspects of physical and mental decline. “It’s never too late to start,” Di Ciacca stated. “If we decide ‘it’s 60, we want to do something about it,’ we can actually reverse a significant amount of that decline.”
How does exercise help?
Strength training
Doing activities that challenge major muscle groups can help counteract muscle loss (sarcopenia), as they stimulate processes that repair and grow your muscles.
Cardiovascular exercise
Activities like walking, swimming or cycling can improve your heart’s ability to supply oxygen and nutrients to muscles. This leads to better stamina and energy levels.
Flexibility
Regular flexibility exercises maintain joint health and movement efficiency. They also reduce stiffness and can improve your range of motion.
Balance
Exercises that challenge balance can help better your coordination and reduce the risk of falling.
Overall health
Regular physical activity supports better sleep, gut health, mental health and reduces the risk of chronic diseases like diabetes and coronary artery disease.
Recommended exercises and practices for seniors
Di Ciacca recommends following the Canadian Society for Exercise Physiology (CSEP) 24-Hour Movement Guidelines, which suggest:
- 150 minutes of moderate to vigorous cardiovascular activity per week (brisk walking, swimming, cycling; for at least 20 to 30 minutes throughout the week)
- Strength training two-to-three times a week (lifting weights or resistance band exercises)
- Daily balance challenges (standing on one leg or balance-focused activities)
- Seven to eight hours of sleep each night
- Less sedentary time (break up long periods of sitting with movement)
Five at-home workouts for seniors
According to Di Ciacca, these are five examples of simple exercises that seniors can try at home to improve their muscle efficiency, flexibility and balance:
1. Chair squats
Simply stand up from a chair and sit back down with control. This exercise helps with lower body strength and is functional for daily activities like getting out of bed or a chair.
2. Weighted marching
Holding light weights or water bottles, march in place. This improves balance and lower body strength.
Push/pull with resistance bands
Attach a resistance band to each hand or a sturdy object and perform pushing and pulling motions. This builds upper body strength.
Single-leg balance
Stand on one leg for a few seconds, then switch. This exercise improves balance and stability.
Big and small flexibility movements
Reach as high as you can to extend your entire body, to be as tall as possible, and pause for a few seconds. Then sit on a chair and draw you knees to your chest, wrap your arms around your knees and bring your chin to your chest, creating a “small” ball. This enhances flexibility and range of motion.
It’s also important for seniors to gradually increase the intensity of their workouts to continue seeing the benefits. “When you’re doing exercises, they have to be somewhat challenging and it has to be a stress on the body. Otherwise, the body is not going to bother to adapt and get stronger,” Di Ciacca stated.
He advised using the Rate of Perceived Exertion (RPE) scale to gauge workout intensity. If 0 is sitting down on a couch, and 10 is being chased by a bear, you want to aim for a five to seven on the scale, Di Ciacca said. You should be exerting energy, getting your heart rate up, but still be able to speak in short sentences.
