Effect of Longitudinal Practice in Real and Virtual Environments on Motor Performance, Physical Activity and Enjoyment in People with Autism Spectrum Disorder: A Prospective Randomized Crossover Controlled Trial.

(1) Background: People with ASD commonly present difficulty performing motor skills and a decline in physical activity (PA) level and low enjoyment of PA. We aimed to evaluate whether longitudinal practice of an activity in virtual and real environments improves motor performance and whether this improvement is transferred to a subsequent practice when changing the environment, promoting PA and providing enjoyment; (2) Methods: People with ASD, aged between 10 and 16 years, were included and distributed randomly into two opposite sequences. The participants performed a 10 session protocol, with five sessions practicing in each environment (virtual or real). Heart rate measurement was carried out and an enjoyment scale was applied; (3) Results: 22 participants concluded the protocol. Sequence A (virtual first) presented an improvement in accuracy and precision and transferred this when changing environment; they also had a greater change in heart rate reserve. The majority of participants reported "fun" and "great fun" levels for enjoyment; (4) Conclusions: The virtual reality activity presented a higher level of difficulty, with greater gains in terms of transference to the real environment. Considering PA, our task provided very light to light activity and the majority of participants enjoyed the task.

Comparisons of Mood States Associated With Outcomes Achieved by Female and Male Athletes in High-Level Judo and Brazilian Jiu-Jitsu Championships: Psychological Factors Associated With the Probability of Success.

ABSTRACT: Brandt, R, Bevilacqua, GG, Crocetta, TB, Monteiro, CBdM, Guarnieri, R, Hobold, E, Flores, LJF, Miarka, B, and Andrade, A. Comparisons of mood states associated with outcomes achieved by female and male athletes in high-level judo and Brazilian jiu-jitsu championships: psychological factors associated with the probability of success. J Strength Cond Res 35(9): 2518-2524, 2019-Moods can be used to predict the performance of athletes in various sports; accordingly, we selected the Brunel Mood Scale (BRUMS) to evaluate mood states of high-level judo and Brazilian jiu-jitsu (BJJ) athletes. The aims of this study were (a) to compare the mood states of high-level female and male athletes in BJJ and judo championships in relation to their performance outcomes and (b) to verify associations between psychological factors and performance in estimating their probability of success. The subjects were 173 grappling athletes (judo, n = 85 and BJJ, n = 88), separated into male (n = 129, 40 winners and 89 nonwinners) and female (n = 44, 23 winners and 21 nonwinners) groups. Each subject's mood state was assessed 60 minutes before the first match using the BRUMS (tension, depression, anger, vigor, fatigue, and mental confusion dimensions). Descriptive and inferential statistics (including logistic regression and variance analysis) were used to evaluate relations between mood states and performance (i.e., winning/losing), with p ≤ 0.05. Analysis showed significant differences between male and female athletes in vigor and fatigue, and differences between male judo and male BJJ athletes in tension, vigor, confusion, and fatigue. Female judo and female BJJ athletes showed significant differences in depression and vigor. Logistic regression revealed that higher levels of anger and tension increased athletes' chances of performing well in a match by 23 and 13%, respectively. In addition, lower levels of depression increased athletes' chances of better performance by up to 32%. Overall, we observed a significant relationship between mood state and sports performance. Thus, coaching staff and athletes should monitor athletes' mood states before competitions to ensure that they are in optimal condition to perform and use psychological interventions to support judo and BJJ preparation.
