Dana Sorensen and Jono Green, co-owners at Symbiotic Training Center, talk about hyper mobility versus hypo mobility in softball athletes - who must have proper joint motion to keep their shoulders and arms healthy throughout season.
Hyper mobility means ranges of motions of joints that are beyond what are considered "normal": this could mean a hyper-extended knee, floppy wrists and elbows that are prone to bending in ways that can cause injury. Athletes who are hyper mobile need to learn to control their joints and train their joints to function in the proper way to prevent injury. This could include strengthening exercises with bands, dumbbells and compound lifts.
Hypo mobility means very limited range of motion in joints, for instance of a player cannot fully extend the elbow or if they have a hard time bending their wrists. These athletes need to work on loosening the muscles to increase joint mobility: this includes dedicated stretching, band work and exercises that can easily be done at home or during a practice warm-up.
