Abstract
Background/Objectives: The purpose of this study is to compare the change of thickness of serratus anterior muscle to different angles of knee flexion when knee push up plus (KPP) exercise is conducting on an unstable surface (sling).
Method/Statistical Analysis: There were 30 healthy young male and female students randomly selected and divided into 3 different groups along different knee flexion angles on an unstable surface (sling). The three groups of ten did KPP exercises on the sling. The muscle was measured before and after the exercise.
Findings: All three groups showed some changes in the thickness of the muscle. The group with the biggest change was the 60° knee flexion, followed by 75° and 90° groups.
Improvements/Applications: Based on the results, all experimental groups showed some differences with KPP exercise conducted on an unstable surface (sling) and especially the group with the lowest angle had the most effect. Therefore, it is concerned that a lower knee flexion angle can be more effective on the KPP exercise.
