Influence of High-Intensity Interval Training on IGF-1 Response, Brain Executive Function, Physical Fitness and Quality of Life in Sedentary Young University Women-Protocol for a Randomized Controlled Trial

What Was Tested

Researchers studied IGF-1 LR3 in this clinical study publication.

Sedentary lifestyles have become a social problem, mainly among women.

At least 77 women will be recruited and randomly assigned to either a HIIT group (12-week exercise HIIT intervention, 3 sessions/week), the HIIT + PA group (12-week exercise HIIT intervention, 3 sessions/week, plus 10,000 steps/day), or a control group (usual care).

Who Took Part

According to the abstract, 77 women were involved.

PubMed tags the participants as women only.

How the Study Was Run

The design is described as randomized and parallel-group.

The women were allocated by chance, so the IGF-1 LR3 group and the comparison group should start out alike.

Groups ran in parallel: each of the women stayed in one arm throughout.

What Was Measured

The primary outcome measure will the chronic change in IGF-1 concentration levels measured in saliva.

Secondary outcome measures will be: (i) executive functions; (ii) body composition; (iii) physical fitness; (iv) physical activity; and (v) quality of life.

PubMed files the paper under topics including Executive Function, High-Intensity Interval Training, Insulin-Like Growth Factor I, Universities, Quality of Life, Physical Fitness and Brain.

The authors tagged it with the keywords HIIT, executive functions, female, insulin growth factor-1, sedentary lifestyle and young adult.

What This Means in Plain Language

The paper is a randomized and parallel-group study of IGF-1 LR3 in 77 women.

The publication is from 2023 (International journal of environmental research and public health), a journal based in Switzerland.
