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.

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
