Final answer:
Balance and power are important skill-related components of fitness in gymnastics. Balance helps gymnasts maintain stability on the apparatus, while power enables them to perform explosive movements.
Step-by-step explanation:
Balance is the ability to maintain stability while performing various movements. In gymnastics, balance is essential for executing precise routines on the balance beam or while performing skills such as splits. Having good balance allows the gymnast to stay on the apparatus and perform complex maneuvers without falling.
Power refers to the ability to generate force quickly. In gymnastics, power is required for explosive movements like tumbling passes and vaulting. It allows the gymnast to generate the necessary height and speed to perform flips, twists, and other acrobatic moves.
