Abstract	Introducao e objetivo: Nos ultimos anos, o treinamento intervalado de alta intensidade (HIIT) tem chamado muita atencao da midia e dos frequentadores de academia em todo o mundo. Apesar da existencia de alguns estudos analisando os efeitos fisiologicos e funcionais do HIIT, ainda sao escassos os estudos analisando respostas perceptuais do HIIT, sobretudo, em mulheres. Assim, o objetivo do estudo foi analisar e comparar as respostas de percepcao subjetiva de esforco (PSE) e afetividade (AFET) entre dois protocolos populares de HIIT. Materiais e metodos: Foram analisadas 20 mulheres saudaveis e destreinadas (33,8 ± 10,0 anos; IMC: 24,2 ± 3,8 kg/m²). A amostra foi submetida a duas sessoes de HIIT em bicicleta estacionaria, cada uma com um protocolo distinto: Tabata e Wingate . Apos ambas as sessoes, os niveis de PSE e AFET foram identificados. Os dados foram analisados atraves do teste t student para amostra em pares (PSE) e Wilcoxon (AFET). Resultados: Tabata apresentou PSE mais elevada em relacao ao Wingate (17,5 ± 2,3 vs. 13,8 ± 2,3). Nao foram observadas diferencas significativas na afetividade entre os protocolos (-2,9 ± 1,1 vs. -2,2 ± 1,3 para Tabata e Wingate , respectivamente), no entanto Tabata mostrou tamanho do efeito medio sobre Wingate . Conclusao: O protocolo Tabata foi percebido como mais exaustivo. A resposta da AFET nao diferiu significativamente entre os protocolos, porem o protocolo Tabata apresentou tamanho do efeito medio sobre Wingate . Assim, o protocolo de Wingate parece ser mais interessante para mulheres destreinadas. ABSTRACT Rated perceived exertion and affective valence in the high intensity interval training: comparison between two popular protocols Introduction and objective: In recent years, high intensity interval training (HIIT) has drawn attention of media and exercise practitioner around the world. Although there are some studies analyzing the physiological and functional effects of HIIT, there are few studies analyzing its perceptual responses, especially in women. Thus, the aim of this study was to analyze and compare the rated of perceived exertion (RPE) and affectivity (AFF) between two popular protocols of HIIT. Materials and methods: Twenty health and untrained women (33.8 ± 10.0 years old; BMI: 24.2 ± 3.8 kg/m²) were included in the sample. The volunteers underwent to randomized two HIIT sessions on stationary bicycle. In each session, one different HIIT protocols was used: Tabata and Wingate . After both sessions, RPE and AFF were measured. The date were analyzed by t student (RPE) and Wilcoxon (AFF) tests. Results: Tabata showed higher PSE values than Wingate (17.5 ± 2.3 vs. 13.8 ± 2.3). No significant differences were observed in the AFF between protocols (-2.9 ± 1.1 vs. -2.2 ± 1.3 for Tabata and Wingate , respectively), however Tabata showed medium effect size over Wingate . Conclusion: Tabata protocol was more exhaustive. The AFF response did not differ significantly between protocols, but Tabata showed a medium effect size than Wingate . Thus, Wingate protocol seems to be more interesting to untrained women.
