Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
* Does elastic band training in combination with maximal mental effort increase strength more than elastic band training alone?
* Does elastic band training in combination with maximal mental effort improve neuromuscular function more than elastic band training alone?
Participants will be randomly assigned to 1 of 3 groups:
* Elastic band training
* Elastic band training with maximal mental effort
* Control
Researchers will compare groups to determine differences in changes in strength, neuromuscular function, and body composition.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
All training sessions will be home-based and virtually supervised by research personnel. Participants will complete 2 training sessions in the first week and 3 training sessions per week for the remaining 5 weeks. Each training session will last about 45-60 minutes and consist of 7 exercises performed in the same order by each participant, including both multi-joint (chair squat, chest press, leg press, back row) and single-joint (knee extension, knee flexion, elbow flexion) exercises. Participants will perform 12 repetitions for each exercise for the first 3 weeks, then volume will be increased by progressing to 4 sets for the remaining 3 weeks. There will be a 60-second rest interval between sets and a similar tempo will be used between groups.
Both training groups will perform the same training protocol, but participants in the maximal mental effort group will mentally urge their muscles to contract maximally during each repetition. That is, despite using a moderate intensity, participants will imagine the feeling of maximal muscle contraction of the primary muscles during each repetition.
Several measures of strength, neuromuscular function, physical function, and body composition will be measured before and after the training or control period.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Elastic Band Training
This group will perform moderate intensity, whole-body elastic band training.
Elastic Band Training
This training intervention will be 6 weeks of moderate-intensity elastic band training, including whole-body and isolated muscle exercises.
Elastic Band Training with Maximal Mental Effort
This group will perform moderate intensity, whole-body elastic band training with maximal mental effort during muscle contraction.
Elastic Band Training with Maximal Mental Effort
This training intervention will be 6 weeks of moderate-intensity elastic band training, including whole-body and isolated muscle exercises, where participants will perform maximal mental effort by imagining maximal muscle contraction during each exercise.
Control
This group will not perform any training and maintain their regular level of physical activity.
No interventions assigned to this group
