Assessment of Trunk Muscle Endurance, Respiratory Functions and Respiratory Muscle Strength in Healthy Individuals

The maximal voluntary inspiratory (PImax) and expiratory (PEmax) pressure measurements of the subjects were performed using Cosmed Pony FX model (Italy 2001) while the subjects were in the sitting position with a nose clip.

Spirometric measurements were conducted with Cosmed, Pony FX (descopt spirometer- Italy 2001) spirometer using a nose clips while the subjects were in 90 degree relaxed sitting position.

Trunk muscle endurance of the subjects was measured using four different tests (Side Bridge Test- SBT, Prone Bridge Test- PBT, Flexor Endurance Test- FET, Sorenson Test- ST).
