Effect of Vegetable and Fruit Enzyme Supplementation on Muscle Activation, Aerobic Capacity, and Blood Biochemical Parameters After High-Intensity Interval Exercise: Feasibility Study of Exercise Design With Exergaming

Taiwan30 participantsStarted 2024-06-25

Plain-language summary

This study explores the effectiveness of fruit and vegetable enzyme supplementation in reducing fatigue and enhancing aerobic capacity in elderly individuals after engaging in high-intensity interval exercise (HIIE) through exergaming. Sixteen elderly female participants were divided into two groups based on pre-test lactate levels: an enzyme group and a placebo group, to ensure comparability. They performed HIIE using Nintendo Switch Ring Fit Adventure, completing eight sets of 20-second high-effort exercises with 30-second rest intervals, totaling 370 seconds of activity. The primary metrics evaluated were blood lactate levels, heart rate (HR), rating of perceived exertion (RPE), and training impulse (TRIMP). Participants in the enzyme group received a fruit and vegetable enzyme supplement in a 30 c.c. dose twice daily for 14 days. The study aimed to determine if enzyme supplementation could effectively mitigate the physiological stress of HIIE and improve exercise outcomes in the elderly.

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.

What they're measuring

Lactate

Timeframe: pre and after-intervention: measurements taken before the test, during the 2 and 4 minute of the test, and 5 and 10 minutes after the test.

Heart rate (bpm)

Timeframe: Collect the heart rate at 20, 50, 80, 110, 140, 170, 200 and 220 seconds in the HIIE test

Borg 0-10 score rating of perceived exertion (RPE)

Timeframe: Collect the RPE at 20, 50, 80, 110, 140, 170, 200 and 220 seconds in the HIIE test
