The tibia works in conjunction with your knee and ankle joints to support most of your body weight. Obviously, the strength of this bone is important to performance in a wide range of individual and team sports. A study published in the Journal of Strength and Conditioning Research shows one way to predict tibial bone strength.
Eighty-six college athletes had their bone mineral density measured along with other indicators of bone strength. They also performed a variety of fitness assessments. Although grip strength and maximum leg press were not good indicators of tibial bone strength, peak powder calculated from vertical jump height was a fairly reliable assessment tool.
