The shoulders moved through a greater range of motion, and loads were calculated that were nearly two times greater at the fast speed compared to the slow speed. Slow propulsion speeds minimize shoulder strain. Free throw success for players in wheelchair basketball ...Effects of global warming already being felt on plants and animals worldwide
