Brief Summary

This research study is comparing the effect of traditional standardized, subjective auto-regulated, and objective auto-regulated resistance training on physiological adaptations and performance measures in adults aged 50 years or older. Traditional standardized resistance training involves prescribing resistance training as a percentage of an individual's one-repetition maximum (i.e., the maximal weight they can lift one time). Auto-regulated resistance training involves adjusting resistance training based on an individual's performance during the session. Subjective auto-regulation involves the resistance trainee providing a subjective rating of perceived exertion based on repetitions in reserve (on a scale from 1 - 10) to adjust the resistance training prescription. A rating of perceived exertion of 10 would mean that the resistance trainee believes that they have provided maximal effort and believes that they could not have performed an additional repetition during the set nor increased the load. Objective auto-regulation involves adjusting the resistance training prescription from a linear position transducer (a device that has a string that attaches to the barbell and provides a velocity value on each repetition). A slower velocity value means a higher perceived exertion and load used, whereas a faster velocity value means a lower perceived exertion and load used.

Study Arms (3)

Subjective auto-regulation training

EXPERIMENTAL

Participants complete their resistance-training sets to termination based on rating of perceived exertion

Behavioral: Resistance training

EXPERIMENTAL

Participants complete their resistance-training sets to termination based on reaching a critical slow velocity

ACTIVE COMPARATOR

Participants complete their resistance-training sets by lifting a prescribed percentage of their estimated one-repetition maximum (as determined from baseline four-repetition maximum strength testing)

Behavioral: Resistance training
