Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The intervention duration was 8 weeks. The participants were required to complete 100 continuous bounces on a trampoline at the maximum intensity they were capable of. The trampoline was located in a laboratory at the University of Canterbury. For the participant to be considered compliant with the protocol, they were required to complete an average of 3 bounce sessions per week across the intervention, with a weekly maximum of 5 bounce sessions. The total bounce height and number of bounces was recorded for each jump session and tracked across the intervention for each participant. This was recorded using TGOMA software, which a series of accelerometers built into the trampoline, which is capable of detecting time of flight of the participant and therefore able to work out the participant's bounce height.

Summary
Brief summary
The purpose of this study was to determine whether high intensity, short duration exercise on a trampoline was a viable exercise modality.

To determine this, after recruitment, prior to the beginning of the intervention, participants will have their weight, height, muscle mass, body fat percentage, V02max, blood pressure, blood cholesterol, blood glucose, and vertical jump assessed.

Participants will then be asked to bounce on a trampoline, to the maximum height they are comfortable with up to x5 /week for 100 bounces.

The measures will be retaken at 4 and 8 weeks.
