I found this paper, Hamstring Myoelectrical Activity During Three Different Kettlebell Swing Exercises.
The paper compared how 3 different swings, the hinge swing, the squat swing, and the double knee extension swing (used in those who train for kettlebell sport) affected the hamstring muscles. The 3 hamstring muscles were divided into 2 parts a medial part (semitendinosus and semimembranosus) and the lateral part (biceps femoris).
What they found was that for all three swings the medial hamstring worked more than the lateral hamstring. They also found that the hinge swing produced the most hamstring muscle activity throughout the entire movement compared to the other swings.
What this means is that when a person is rehabilitating a hamstring strain we may want to progress from a swing that produces less strain to one that produces more.
