Resistance Training: Why?

I have spoken about cardio-respiratory training previously, however, overall fitness is the sum of many components. In addition to cardio, resistance training has benefits as well. Besides shifting the balance between fat and muscle, resistance training can help to improve bone density, reduce the instance of injury around joints, and provide a better quality of life. I’ll break these groups down further:

Lean Muscle Mass

Resistance training, through the process of hypertrophy (increasing the size of muscle cells or fibers) increases the size of the overall muscle. This can make you stronger and increases the body’s metabolic needs (therefore increasing the amount of Calories that are used to produce energy). It has been shown through numerous trials that individuals who perform resistance training are less prone to lower-back pain, musculoskeletal injuries, and decreased quality of life!

Bone Health

When we usually think of bone what is the first thing that comes to mind? It probably is not the idea of bone being a living, ever-changing structure; it is however, just that. Bone is an ever-changing part of the body, as much as any other organ or type of cell; it is constantly being broken-down and built-up depending on the stresses and hormones present at a particular time. Resistance training or exercise with weight bearing stresses the bone, much like muscle, in a way that necessitates the bone to become stronger. Research has shown that individuals who perform resistance training have higher bone mineral density (BMD) than those who do not include resistance training in their exercise regimens. Increased BMD is highly correlated with a decreased risk of osteoporosis and fracture.

I think it is easy for us to interpret just these two factors into a model of how overall quality of life can be improved!

Next Week will follow with recommendations on what, how, and for how long healthy individuals should perform resistance training in order to reap the aforementioned benefits!
