Final answer:
Plyometrics are best performed on grass playing fields, basketball courts, or tartan tracks due to reduced impact on joints, improved traction and grip, and consistent surface for jumping.
Step-by-step explanation:
Plyometrics are best performed on grass playing fields, basketball courts, or tartan tracks due to several reasons. Firstly, these surfaces provide reduced impact on joints compared to harder surfaces like concrete. The softer surface absorbs some of the force generated during jumping, resulting in less stress on the joints. Secondly, these surfaces offer improved traction and grip, which is important for generating power during plyometric exercises. Lastly, these surfaces provide a consistent surface for jumping, ensuring that the athlete's movements are stable and predictable.
