Brief Summary

Mental imagery is effective for improving motor skills as well as increasing muscles strength and size. Strength is also maintained after immobilization of a muscles when engaging in imagery. This may have important implications for rehabilitation settings and for sedentary individuals. We may not be able to get people wot exercise but if they can maintain muscles size and strength via imagery this may have beneficial health and functional outcomes.

Conditions

Using Imagery to Maintain Muscle Mass Gains in the Quadriceps

Outcome Measures

Primary Outcomes (1)

• Muslce mass (grams) determined by the DEXA body scan.

  4 weeks

Secondary Outcomes (1)

• Muscle strength

  4 weeks

Study Arms (3)

Imagery Group

EXPERIMENTAL

The imagery group, will sit on the leg press and image completing 3 sets of leg press. The imagery group will be asked to fill out the Movement Imagery Questionnaire -revised as this gives us a measure of imagery ability. The imagery group will be given an imagery script prior to imaging. Weekly manipulation checks will be completed to ensure that participants are imagining what they are supposed to.

Behavioral: Imagery

Maintenance Group

ACTIVE COMPARATOR

The maintenance group will continue to perform the leg press three times per week at 1/3rd of final strength assessment. This is the percentage of intensity recommended to maintain muscle mass and strength gains by the American College of Sports Medicine.

Behavioral: Muscle Maintenance

Control Group

ACTIVE COMPARATOR

Control group will come in 3 times per week for 20 minutes and complete 3 sets of 8-12 of a bicep curl 1/3 of predicted 1 RM

Behavioral: Bicep Curls

Interventions

Imagery BEHAVIORAL

Prior to exercising participants will be given an imagery script. Afterwards, participants will imagine completing the leg press.

Imagery Group

Muscle Maintenance BEHAVIORAL

Participants complete the leg press exercises at an intensity that promotes muscle maintenance but not muscle growth

Maintenance Group

Bicep Curls BEHAVIORAL

Control group participants will complete a bicep exercise at a maintenance training intensity.

Control Group
