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.

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 60 participants
Allocation: Randomized
Intervention Model: Factorial Assignment
Masking: Single (Participant)
Official Title: Maintaining Muscle Mass Gains
Study Start Date : January 2017
Estimated Primary Completion Date : April 2018
Estimated Study Completion Date : April 2018

Arm Intervention/treatment
Experimental: Imagery Group
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
Prior to exercising participants will be given an imagery script. Afterwards, participants will imagine completing the leg press.

Active Comparator: Maintenance Group
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
Participants complete the leg press exercises at an intensity that promotes muscle maintenance but not muscle growth

Active Comparator: Control Group
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
Control group participants will complete a bicep exercise at a maintenance training intensity.

Primary Outcome Measures :
  1. Muslce mass (grams) determined by the DEXA body scan. [ Time Frame: 4 weeks ]

Secondary Outcome Measures :
  1. Muscle strength [ Time Frame: 4 weeks ]
