Verbal encouragement (VE) is considered as external motivation provided by physical education teacher. For this reason, study aimed to examine the effects of VE on psychophysiological and affective responses during small-sided games (SSG). Sixteen male school students (age: 17.37 ± 0.48 years) completed four sessions a 4-a-side SSG. Two occurred with (SSGE), two did not include (SSGNE). Heart rate was continuously recorded, rating perceived exertion (RPE) blood lactate concentration ([La]b)...
