There's good news that should serve as an encouragement to all of us when it comes to fitness, walking endurance, and health. In a classic study of walking and mortality in 700 men enrolled in the Honolulu Heart Program, the mortality rate among the men who walked less than one mile per day was nearly twice the rate of those who walked more than two miles per day. (Studies of women showed similar results). In another study, data collected on more than 41,000 men and women from 1990 to 2001 were analyzed to find the relationship between walking and mortality. It was reported that men and women who walked 30 minutes or more per day during the study period had fewer deaths than those who walked less than 30 minutes. Interestingly, even men and women who smoked or were overweight were protected from early death if they walked more than 30 minutes per day.
Remember to push your buttocks out as you bend to maintain a straight back posture, and do not bend your knees past your toes. Once you're comfortable with that, try doing a half squat against a wall. This can be a more challenging move — especially if you get all the way into a seated position — so you may want to make sure you have someone there to assist you.
Strength training differs from cardiovascular training. One involves aerobic training, whereas, the other involves working and strengthening your muscles. According to Wikipedia, strength training is “…a type of physical exercise specializing in the use of resistance to induce muscular contraction which builds the strength, anaerobic endurance, and size of skeletal muscles.”
Yes, some seniors can be frail and have low energy reserves but most of us will respond well to moderate sessions of weight training. Numerous studies have shown that strength training for seniors and other exercises for seniors done regularly not only builds up bone and muscle but counteracts the weakness and frailty that usually comes with aging.
Exercise benefits much more than just the body — you can also improve your mental and emotional health by maintaining an active life. And if you have fun while you’re being active, chances are you’ll want to continue participating in that activity. Join a walking group so you can exercise and socialize at the same time, listen to music while you garden or work outside, call a friend and take a water aerobics class together, or join an organized club or sport. Stay active, stay involved, and you’ll stay healthy!
To quote Gavin McHale, a Winnipeg-based Kinesiologist and Certified Exercise Physiologist who works primarily with older adults: “Strength is the fountain of youth. Benefits of resistance training (strength training), and subsequent strength gains, in older adults include better control of symptoms of chronic disease, pain and depression, as well as prevention of falls, maintaining existing muscle mass, improving posture and stability, increasing bone density and remaining functional.”
In a large study of 439 adults (aged 60 and older) with osteoarthritis who did either aerobic exercise (walking) or resistance exercise (weight lifting) for 18 months, participants in the aerobic exercise group had a 10% decrease on a physical disability questionnaire, a 12% lower score on a knee pain questionnaire, and outperformed non-exercising individuals in the study on the following tests: a six-minute walk test (they walked further); the time it took them to climb and descend stairs; the time it took them to lift and carry 10 pounds; and the time it took them to get in and out of a car. In the weight-lifting, group, there was an 8% lower score on the physical disability questionnaire, 8% lower pain score, greater distance on the six-minute walk, and faster times on the lifting and carrying task and the car task than in the individuals in the study who did not exercise.
The good news here is that muscle patterning improves within days of starting a weight-lifting program, even without any increase in muscle mass. This explains the 113% increase in strength experienced by the residents of the nursing home in Boston in the previously cited study. In a different study that specifically investigated this phenomenon, 67- to 81-year-old men lifted weights for six weeks while hooked up to electrodes that measured their nerve and muscle patterning (an electromyogram machine). The results showed that the men experienced a 25% increase in the patterning of the muscle along with a 35% increase in strength, all without significant increases in size.
Crunch: It presents the same problem as the leg press. You flatten your lower back against the floor as you raise your head and shoulders and feel the squeeze in your abdominal muscles, then go back into an arch when you lower yourself. Although you aren’t using much weight when you do it—just a fraction of your body’s weight—you typically do lots of repetitions.
This one sounds tough, but you don't have to be an engineer or tech wizard to take on the challenge. By following basic guidance and instructions, anyone can build their own computer. It's fun to learn what parts go where and why, and with having the ability to choose specific parts or components, your personally built computer is more than likely to out-perform one you would pick up at the store.
