About this study
Official title: The Effect of Asymmetric Postural Loading on the Movement of the Right Hemidiaphragm
The aim of this study is to investigate the movement of the right hemidiaphragm when lifting a load with the left and right hand.
Read the detailed description
Hemidiaphragm movement will be assessed by m-mode ultrasonography in a standing position. The study will include 30-40 healthy adult volunteers. The examination will consist of two tidal inspirations and expirations, two inspirations and expirations during lifting the kettlebell with the left hand and two inspirations and expirations during lifting the kettlebell with the right hand. The weight of the kettlebell will correspond to about 10% of the participant's body weight.

- Healthy
What is being measured
The primary outcome is the main question the study is designed to answer.
Hemidiaphragm movement
Distance of the diaphragm from the ultrasound transducer in millimeters during tidal breathing, and when lifting a load with the left and right hand.
Measured: 7 months
