Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to determine whether inversions (specific yoga postures in which the heart is higher than the head) and other dynamic and static yoga postures affect heart rate variability, oxygen uptake, blood pressure, blood parameters and other objective measures of health, and a variety of subjective and objective measures of health in female and male individuals in Sweden.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This randomized, controlled trial involving 44 male and females in Sweden will investigate whether yoga inversions and semi-inversions and other dynamic and static yoga postures will affect the following variables: heart rate variability, oxygen uptake, anthropometric variables, common symptoms in general practice, sleepiness, sleep quality and recovery/recuperation after sleep, blood pressure, blood lipids, blood proteins, blood sugar, salivary cortisol, hand grip strength, relaxation and recovery perceived stress, self-rated health, rating of perceived exertion, satisfaction with life, and work-family conflict.

Participants will be divided into an intervention group and a passive control group. The intervention group will participate in six to ten weeks of yoga classes. The classes will be held 1-2 times a week for approximately one hour each and will include yoga poses and breathing techniques. The control group will not participate in any intervention but will conduct their lives as usual.

The variables will be assessed at baseline; at the end of the intervention; and three, six, and twelve months after the end of the intervention.
