About this study

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.
