How the Length of Your Bones Affects Your Power Output

The length of your bones affects how much power you produce during exercise. If you have short bones, then your muscles will not be able to move as fast or powerfully as if they were longer. You might even feel tired after exercise because your muscles are not working hard enough. When it comes to strength training, the amount of weight lifted is determined by the amount of force produced with each pound of weight lifted. A person’s height and weight affect their strength. For example, a 5’6″ man would lift more than a 5’9″ man. However, the amount of force required to lift the same amount of weight depends on both height and weight. A shorter person could easily only lift half as much weight as someone who was taller and heavier. There are many reasons why one might have short bones. One reason may be genetics. Another reason may be poor nutrition or lack of physical activity in childhood or adolescence.


How much you exercise can have an effect on how strong you are. The more you move your muscles, the stronger they become. If you do not exercise for an extended period of time, your muscles will begin to weaken.

This is why you may notice yourself getting out of breath more easily if you suddenly stop exercising. As well, your bones may become shorter and weaker.
