Summary

The investigators propose to compare the effects of a 12-week load resistance training program to a velocity resistance training program on ultrasound measures of quadriceps muscle quality in a healthy, older adult population. As secondary measures, The investigators propose to compare the effects of these exercise programs on maximal strength, power, and functional movements such as the chair sit-to-stand and gait speed. Further, The investigators will evaluate the impact of each protocol on cognitive function.

Conditions

  • High-Intensity Interval Training
  • Resistance Training

Interventions

OTHER

High-velocity interval training

For the velocity training protocol, the 11 exercises will be completed at 40% of their 1RM. In the first three weeks of training, the loading volume will be increased gradually. During week one participants will complete one set of each exercise. Week two will consist of two sets, and weeks 3-12, three sets. Keiser pneumatic resistance machines are interfaced with a laboratory computer, which allows the transfer and analysis of data including force, velocity, and power.

OTHER

Resistance training

For the load training protocol, the 11 exercises will be completed at 79% of their 1RM. In the first three weeks of training, the loading volume will be increased gradually. During week one participants will complete one set of each exercise. Week two will consist of two sets, and weeks 3-12, three sets. Keiser pneumatic resistance machines are interfaced with a laboratory computer, which allows the transfer and analysis of data including force, velocity, and power.
