Introduction:

in recent years, High-Intensity Interval Training has been recognized as a non-pharmacological treatment for diseases like type II diabetes in a variety of populations. However, few studies about this topic have been conducted with elderly people.

Objective:

determine the acute effect of a High-Intensity Interval Training session on glucose levels in physically active elderly people.

Methods:

an experimental study was conducted. The sample was 19 elderly people aged 60-85 years. The group participated in a High-Intensity Interval Training session in which strength and cardiovascular resistance exercises were combined. The 12 exercises performed had a duration of 30 seconds' work and 10 seconds' rest. The intensity of the session was controlled with the OMNI-GSE Effort Perception Scale. Measurements were taken of the height (cm), weight (kg) and body mass index of participants. Blood glucose levels were gauged before and after the session.

Results:

a significant reduction in blood glucose levels was obtained after the conduct of the High-Intensity Interval Training session (pre: 140.5 mg/dl and post: 116.1 mg/dl; p < 0.01).

Conclusions:

in only one session, High-Intensity Interval Training reduces blood glucose levels in elderly people.
