RESUMEN
Energy is essential to human daily functioning and performance. However, the association of mental energy with athletes' performance has rarely been examined. We attempted to examine the pre-competition mental energy-performance relationships by two studies. Study 1 administered Athletic Mental Energy Scale (AMES, Lu et al., 2018) to nine elite physically-disabled table tennis players one day before competition in 5 international tournaments. Then, we collected their subjective performance after each competition. In Study 2, we sampled 77 National-level physically-disabled table tennis players and examined the pre-competition mental energy-performance relationship as the procedure in Study 1. Results from Study 1 provided initial findings of how pre-competition mental energy is associated with performance and portrayed in elite physically-disabled table tennis players. Results from Study 2 further confirmed the pre-competition mental energy- performance relationships. We suggested future studies to examine the mental energy-performance relationships in physically-disabled and abled athletes and different sports.
