💥Should you use an arm swing when you test your athletes? This is a question that has been around since force plates first entered into the world of human performance. The short answer is: neither is right nor wrong...it depends what you’re looking to assess. Non-Arm Swing • Pros: Eliminates upper body movement which yields a “cleaner” force-time curve, which makes it easier to assess minute changes over time (I.e. fatigue, readiness). It also makes the jump a true test of lower body dynamic strength. • Cons: Might take the athlete longer to learn how to jump without arms. Their jump height will be lower and the athlete may become discouraged (educating your athlete is 🔑 here). Arm Swing • Pros: This will be the athlete’s maximal vertical jumping capability. Their jump height will be higher because they are able to generate more momentum with the use of an arm swing.
