Effects of Integrative Neuromuscular Training on Motor Performance in Prepubertal Soccer Players.

ABSTRACT: Menezes, GB, Alexandre, DR, Pinto, JC, Assis, TV, Faigenbaum, AD, and Mortatti, AL. Effects of integrative neuromuscular training on motor performance in prepubertal soccer players. J Strength Cond Res 36(6): 1667-1674, 2022-The present study examined the effects of integrative neuromuscular training (INT) on motor performance in prepubertal soccer players. Subjects were randomly assigned to the experimental group (INT; n = 20, age: 8.2 ± 1.2 years; body mass: 28.4 ± 6.4 kg; height: 1.3 ± 0.1 m) or the control group (CON; n = 18, age: 8.5 ± 1.3 years; body mass: 32.8 ± 8.9 kg; height: 1.3 ± 0.1 m). Integrative neuromuscular training program was performed twice per week during the 12-week training intervention. Balance, flexibility, countermovement vertical jump height (CVJH), sprint speed, and change of direction speed (CODS) were assessed in both groups at baseline, sixth week and 12th week. A mixed model repeated measures analysis of variance was used to examine the group changes in performance for each variable. There was a time effect for balance in the INT from pre to 12th weeks (p < 0.001, g = 0.72), and from 6th to 12th weeks (p = 0.005, g = 0.34). An interaction effect for balance was also observed between INT and CON after the 12th week. A time effect in flexibility was observed in INT from baseline to 6th and 12th weeks (p = 0.02; g = 0.45 and p < 0.001; g = 0.71) and from 6 to 12th weeks (p = 0.003; g = 0.24). There was a time effect in CVJH, from baseline to 12th week and from 6th to 12th weeks (p < 0.05; g = 0.34 and g = 0.53, respectively). There was no significant between-group speed performance change. A time effect was found in CODS in INT, but only from baseline to 12th week (p = 0.02; g = 0.31). There were significant improvements in the percent change (Δ%) from baseline to 12 weeks (p < 0.05) for balance, flexibility, and CVJH in INT. These findings indicate that the addition of an INT program to soccer practice can improve selected motor performance skills in prepubertal soccer players.

Efeitos dos jogos reduzidos sobre os marcadores psicofisiológicos de atletas de futsal feminino / Effects of small-sided games on psychophysiological markers of female futsal athletes

O objetivo do estudo foi analisar o efeito da quantidade de balizas em jogos reduzidos no futsal (JRF's) sobre a carga interna e resposta afetiva. Participaram do estudo oito atletas adultas de futsal feminino, que treinavam regularmente cinco vezes por semana. Foram analisadas duas sessões de treinamento: 1) JRF1baliza 4 x 4 com uma baliza para cada equipe; 2) JRF3balizas4 x 4 com três balizas para cada equipe. A ordem dos JRF's foi escolhida de forma randomizada. Para análise da carga interna utilizou-se a escala CR 0-10 de percepção subjetiva de esforço (PSE) e para a resposta afetiva, utilizou-se a escala de sentimento (feeling scale). Utilizou-se o teste t pareado para análise da resposta psicofisiológica, considerando significativo um valor p < 0,05. Em nossos resultados os valores de P SE foram semelhantes entre os JRF's (JRF1baliza: 4,5 ± 1,7 vs. JRF3balizas: 4,4 ± 0,7, p > 0,05) da mesma fo rm a para a resposta afetiva (JRF1baliza: 0,2 ± 0,8 vs. JRF3balizas: 0,1 ± 1,0, p > 0,05), adicionalmente observou-se que os valores de PSE fixaram-se em "um pouco difícil" e a resposta afetiva permaneceu positiva durante ambos os JRF's. Em suma, conclui-se que os JRF1baliza e JRF3balizas obtiveram respostas semelhante nos marcadores psicofisiológicos (PSE e Afeto) em atletas adultas de futsal feminino...(AU)

The aim of this study was to analyze the effect of the number of goals in futsal small-sided games (SSG) on the internal load and affective response. Eight adult female futsal players regularly training five times a week participated in the study. Two training sessions were analyzed: 1) SSG1goal 4 x 4 with one goal for each team; 2) SSG3goal 4 x 4 with three goals for each team. The order of SSG was chosen in a randomized fashion. The CR 0-10 scale of rating of perceived exertion (RPE) was ch o sen to analyze internal load and for the affective response, the feeling scale was used. Paired t test was used t o analyze the psychophysiological response, considering a value p < 0.05. It was observ ed t hat t he RPE values were similar between the SSG (SSG1goal: 4.5 ± 1.7 vs. SSG3goal: 4.4 ± 0.7, p > 0.05) in the same way for affective response (SSG1goal: 0.2 ± 0.8 vs. SSG3goal: 0.1 ± 1.0, p > 0.05), it was further observed that the RPE values were set as "a little difficult" and the values of the Feeling Scale was p o sit iv e durin g bo th SSG. In summary, the SSG1goal and SSG3goal being performed in random order with seven days rest between them, obtained similar responses in the psychophysiological markers in adult female futsal players...(AU)
