O objetivo desse estudo foi analisar o estado de humor, a motivação e a impulsividade de escolares participantes dos Jogos Escolares da Juventude.

Os instrumentos utilizados foram a escala Brunel mood scale; a escala para a motivação para atividade física medida revisada (MPAM-R) e a escala de comportamento impulsivo (UPPS). Os resultados indicaram que o humor dos escolares apresentou fator positivo, com elevados níveis de vigor; as dimensões que mais motivam os escolares se relacionam à motivação intrínseca; e a impulsividade se caracterizou pela busca de sensações e urgência, indicando que tendem se engajar em situações e atividades excitantes e a curto prazo.

The present study aimed to compare the mood, motivation and impulsivity of student-students participating in Youth School games and their analysis between genders. A cross-sectional survey was conducted by 147 students aged 12 to 17 years (14.53 ± 1.51 years; 51,70% male). The following scales were used: 1) Brunel Mood Scale; 2) Motivation for Measured Physical Activity reviewed and 3) Impulsive Behavior Scale. For comparison between the groups, the Mann-Whitney U test was used and the effect size was calculated by means of Cohen d. The results showed that female schoolchildren had higher scores of anxiety, anger, confusion, depression, fatigue, lack of perseverance and premeditation. On the other hand, male schoolchildren presented higher scores in appearance and health, being more motivated by extrinsic factors in relation to the female sex. Therefore, it is suggested that training strategies be adapted according to gender, in view of their respective characteristics.
