Effect of Verbal Encouragement on Performance and Affective Responses in Male Sport Science Students during Sprint Modalities.

This investigation aimed to examine the effect of verbal encouragement teacher to student (VETS) versus verbal encouragement student to student (VESS) on physical performance and affective responses during different modalities of sprint tests in active male students. In a randomized crossover design, twenty-two male sport science students (age: 21 ± 1.2 years, body height: 1.77 ± 0.3 m, body mass: 76.6 ± 2.1 kg, BMI: 22.9 ± 1.3 kg·m -2 ) performed linear and change-of-direction sprint tests under one of three conditions: (1) VETS; (2) VETS; (3) no verbal encouragement. In each condition, participants performed the 20 m sprint test, the 10 × 2 sprint test, and the L sprint test. The assessed parameters comprised physical performance, rating of perceived exertion (RPE), and a feeling scale. Post hoc test analysis indicates a significant increase in physical performance during VETS and VESS conditions compared to the control condition due to a decrease in sprint in line 20 m (VETS: p < 0.001, d = 0.55; VESS: p = 0.016, d = 0.41), sprint 10*2 (VETS: p < 0.001, d = 0.64; VESS: p = 0.05, d = 0.36), and sprint L (VETS: p = 0.001, d = 1.19) times compared to the control condition. Moreover, the feeling score was greater after VETS compared to other conditions ( p = [<0.001-0.001], d = [0.77-1.18]). In addition, the RPE had no effect on sprint performance between the different conditions. It is indicated that VETS, rather than VESS, is a more significant and effective way to increase effort intensity and positive feelings during sprinting modalities.
