Summary

Adults are often encouraged to exercise to maintain or improve bone health. However, there is evidence that exercise does not always lead to increases in bone mass, and exercise could lead to bone loss under certain conditions. Endurance exercise can increase bone resorption following an exercise bout, which may explain why bone does not always favorably adapt to exercise, but it is unclear if this also happens with resistance exercise. Further, it is not known how exercise training influences blood markers of bone resorption for either endurance or resistance exercise. The purpose of this study is to determine 1) if resistance exercise causes a similar increase in bone resorption as endurance exercise; and 2) if exercise training influences the increase in bone resorption following exercise for both endurance and resistance exercise.

Conditions

Interventions

BEHAVIORAL

10 Weeks of Supervised Resistance Exercise Training

Participants will be randomized to complete 10 weeks of either resistance (weight lifting, hopping) supervised exercise. Exercise will be 3x per week for 1 hour each session. There are a total of 30 exercise sessions.

BEHAVIORAL

10 Weeks of Supervised Endurance Exercise Training

Participants will be randomized to complete 10 weeks of endurance (stationary cycling) supervised exercise. Exercise will be 3x per week for 1 hour each session. There are a total of 30 exercise sessions.
