Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
supervised core strengthening program run by an exercise scientist twice per week for 8 weeks
versus
home based intervention consisting of one initial instruction session and written instructions for a home based program of 2 sessions per week for 8 weeks

The instruction session for the home-based group took place in the first week of the intervention and consisted of verbal instructions and demonstrations of the exercises in the program, including feedback on exercise execution. They were also shown how to record the exercises executed during their training sessions in their exercise journal.

The core strengthening programs for the supervised group and the home based group are identical (except for the supervision vs written instructions) and consist of:
Warm up; cat/camel and abdominal contractions (supine, quadruped and side bridge on knees)
The exercises consisted of Dead bug, side bridging, bird-dog, hip abduction in side lying, lunges and stability ball exercises. The number of sets and duration of contractions were gradually increased throughout the 8 week program, as was the complexity of the exercises.

All exercise sessions were designed to take approximately 25 minutes to complete, so total training time was 2 x 25 minutes per week for 8 weeks.
