Many movement screens look at flexibility and use 90 degrees. Why 90? Why not 85 or 110 degrees? My experience is that a range of motion reserve is needed before heavy competition as the strain decreases flexibility and scores drop like player weights during summer doubles. I think the most difficult sale is getting athletes, especially the tight ones, to invest in a flexibility program. No record boards for best overall range of motion on college walls that I see. My guess is that more stop light light charts to show dangers is far more effective than having a number score. My experience is that great hamstring strength and ranges past 90 work, close to 115 degrees.
