Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Participants will conduct eccentric weightlifting (dumbbells) with the healthy arm, which involves lowering a dumbbell.
All training will be instructed and monitored by an investigator and/or a trained exercise physiologist.
The training program runs for 8 weeks, participants come in twice a week for approximately one hour per session. Over the course of 8 weeks, the weights will increase as a percentage of the maximum weight the participants can lift at the start of the experiment (10% 1-repetition maximum weight at the start of the 8 weeks, increasing by 10% each training week).
Before the training program, there will be 2 sessions for baseline testing. These sessions will approximately be 1.5 hours each.
Four weeks after the program there will be a post-measurement which will take around 1.5 hours.
All training and assessment will be done in the 'NeuroRehabilitation and Robotics lab' at the ECU in Joondalup, WA.

Efficacy
Statistical methods / analysis
A recent meta-analysis (Manca et al. 2017) demonstrated a 17.7% increase in muscle strength in the untrained arm after eccentric training. The reported effect size is moderate-to-large. Because this is a phase 0 trial, we will only include a small number of participants (n= 15) for each group, which makes 30 participants in total.
