I have recently been working with my mother who has had bi-lateral hip replacements. In the past two years, she has been able to go from barely being able to walk up stairs and get in and out of a chair without assistance, to easily climbing stairs, getting not only out of chairs and off the floor, and this summer, hiked 2 miles up a mountain with our family. I use traditional strength training methods with my mother, but have also added in some medicine and kettlebell work as well as modified agility work and plyometrics.

Power Training for Seniors
It has become more widely accepted that individuals can and should stay active well into their later years and by that, we mean their seventh and even eight decades. The question that remains in a lot of people’s minds then becomes, what sort of activity is most beneficial for older individuals to engage in that will give them the most physical benefit and also improve their quality of life? Ideally, it should be fun, improve daily function and mobility, increase bone density, and decrease disability.
What exercise method could possibly encompass all of these benefits? Why resistance training, of course. And now, older folks are not just limited to regular old constant velocity resistance training; researchers are now concluding that power training may be superior for enhancing physical well-being and quality of life in older adults.
A study recently published by the Department of health and Exercise Science at Wake Forest University concluded that high velocity power training had many benefits that went above and beyond those of traditional strength training programs for older individuals. These benefits included not only increases in strength and mobility, but self-reported increases in self-efficacy, satisfaction with daily living, and quality of life.
The benefits of power training over traditional strength training have been investigated regarding the effect on bone loss in post menopausal women as well. The conclusions have shown that power training is at least, if not more, effective at preventing bone mineral density loss. Power training was not found to be additionally stressful or painful as compared to the traditional resistance training.
So, what exactly is power training?
Power training, as described in most of the studies cited for this article, differs from traditional weight training simply in the speed with which the weight is lifted. With traditional weight training, the weight is lifted and lowered at a constant speed. With power training, the weight is lifted at a much faster rate than it is lowered. This faster rate of lifting creates more force and for the muscle, has the effect of lifting a heavier weight. Creating more force recruits more muscle fibers and puts more positive stress on the bones and tendons. Stress on the bones and tendons is a good thing in that it causes the bones and tendons to remodel themselves to become stronger in order to handle a heavier load. Heavier loads are not necessary, simply an increase in lifting tempo.
For all fitness participants, specialized training such as power training must be adapted for with foundational training to develop a baseline of strength and conditioning. For older adults, this period of adaptation is especially important to avoid injury, maintain independence, and gain strength. Working with a qualified trainer is a safe way to develop this foundational strength and create a power training program for use in the home or gym.
