Body Composition

Players' body composition will be officially measured using state-of-the-art, medical-grade technology that will provide precise insights into height, weight, skeletal muscle mass, BMI and more. Players will step on scales using bioelectrical impedance analysis (BIA), a method for measuring body composition, including muscle mass, body fat, and total body water.

Our scales will then produce several metrics giving insight into the prospect’s body composition. Height will be measured using a digital stadiometer to get precise height measurements.

Grip Strength

Hitters' grip strength will be tested using a digital hydraulic dynamometer. Grip strength is an essential component to bat strength and controlling the barrel. Hitters will be put through a max strength test on both hands, shedding light on hand strength and potential power and bat control down the road.
