Objetivos: Comparar a taxa de desenvolvimento de torque (RTD) dos músculos extensores e flexores do tronco em indivíduos saudáveis que praticam modalidades de treinamento com diferentes padrões de movimento durante exercícios para o tronco, como Pilates, CrossFit e treinamento resistido tradicional.
Métodos: Trinta e duas voluntárias, com idade média de 23,72 ± 3,4 anos, participaram do estudo e foram alocadas em um dos quatro grupos com base na experiência de treinamento: Pilates, CrossFit. As participantes incluídas nos grupos treinados deveriam ter histórico de prática em suas respectivas modalidades. As participantes incluídas no grupo controle (CON) não deveriam ter praticado exercícios regularmente nos últimos seis meses. Foram utilizados testes de normalidade, homogeneidade e esfericidade. Os valores de taxa de desenvolvimento de torque (RTD) e torque isométrico de pico (IPT) foram comparados entre os grupos por meio de ANOVA de uma via, seguida de testes post-hoc de Bonferroni. Adotou-se nível de significância de p < 0,05.
Resultados: Não foram encontradas diferenças significativas quanto à idade e massa corporal. Mulheres com experiência em treinamento CrossFit apresentaram valores significativamente maiores de IPT e RTD do tronco durante extensão e flexão isométricas. O IPT na flexão do tronco também foi significativamente maior para as participantes que praticavam CrossFit. A RTD para extensão e flexão do tronco não diferiu entre participantes com experiência em Pilates, treinamento resistido tradicional e aquelas sem experiência em treinamento físico. Além disso, o grupo CF apresentou valores significativamente maiores de RTD em todos os intervalos de tempo analisados.
Conclusão: Os resultados confirmam que mulheres que praticam CrossFit apresentam maior capacidade de produção rápida de força nos músculos flexores e extensores do tronco. A prática regular de CrossFit resulta em RTD superior quando comparada ao treinamento resistido tradicional, ao Pilates e ao estilo de vida sedentário em mulheres. A força máxima do tronco também é maior em mulheres que praticam CrossFit.
