Because of the neuromuscular nature of their disability, CP7 and CP8 swimmers have slower start times than other people in their classes. They are also more likely to interlock their hands when underwater in some strokes to prevent hand drift, which increases drag while swimming. CP8 swimmers experience swimmers shoulder, a swimming related injury, at rates similar to their able-bodied counterparts. When fatigued, asymmetry
