Quick Summary

In this 8-week randomized controlled trial, a static stretching program and a resistance training program had similar effects on strength and muscle mass in recreationally active participants.

What was studied?

The effect of static stretching on maximal strength, muscle mass, and flexibility of the pectoralis major (the largest chest muscle), compared to resistance exercise.

Strength was measured unilaterally (i.e., the left and right pectoralis major muscles were assessed individually) using an isometric maximum strength test, muscle mass was measured using ultrasound, and flexibility was measured using the shoulder pass through test (shown below).
