"Can pre-workout supplementation with gelatin and vitamin C improve force transfer and performance in highly trained athletes?"
18-25 years old
Healthy Volunteers:
nutrition supplement, exercise, performance, athlete
Other study
We have recently discovered that a nutritional supplementation with gelatin and vitamin C might help improve force transfer and performance in highly trained athletes. We hope to further study this by measuring explosive performance with this nutritional intervention. To test this idea, study participants will follow a nutritional supplementation and exercise schedule for about 3 weeks. We expect that this project will determine the effects of this a simple and safe nutritional intervention on explosive performance
This study requires

The nutrition intervention involves drinking gelatin with vitamin C (mixed in liquid) or a placebo control before each scheduled exercise period for 3 weeks

You will be asked to participate in a baseline exercise testing session which will last about 20 minutes.

You will be asked to complete 3 weeks of prescribed exercise for 3 days per week (Monday, Wednesday, Friday at the same time of day) with a testing session on Friday of each week.

Food intake tracking 24 hrs prior to each exercise session
