Resumo

Objetivo: Os objetivos foram mensurar as respostas psicofisiológicas durante sessões de cross-training em mulheres obesas, com foco na frequência cardíaca (FC), pressão arterial (PA), gasto calórico e percepção subjetiva de esforço (PSE). Além disso, examinou a relação entre gasto calórico e intensidade de esforço. Métodos: Este estudo observacional do mundo real envolveu dez mulheres obesas (idade média: 31,5 ± 6,2 anos, IMC: 34,2 ± 3,7 kg/m², experiência de treinamento cruzado: 5,3 ± 3,4 meses). Os participantes foram submetidos a três sessões individuais de treinamento cruzado. O tipo de treinamento e a duração de cada sessão foram registrados. A PA foi medida antes e depois, juntamente com a FC de repouso, FC média, FC máxima e PSE pós-treino. A carga interna e o gasto calórico foram calculados. Resultados: Entre as 30 sessões observadas, não houve diferenças significativas na duração do treinamento por tipo. O gasto calórico foi em média de 272,3 ± 76 kcal. A PA sistólica aumentou significativamente (de 129 ± 8 mmHg para 160 ± 16,5 mmHg), assim como a PA diastólica (de 90,3 ± 6,7 mmHg para 113,6 ± 14,9 mmHg, p < 0,001). A FC média foi de 136,9 ± 14,8 bpm (73,6 ± 7,3% da FCmáx) e a FC máxima atingiu 181,9 ± 12,1 bpm (97,8 ± 6,1% da FCmáx). Os participantes passaram mais tempo igual ou superior a 80% da FCmáx prevista. A PSE média foi de 5,7 ± 2,2 ua, o que está significativamente correlacionado com tempo de exercício acima de ≥90% da FCmáx (r = 0,37; p = 0,046, tamanho do efeito = 0,39). Conclusões: As sessões de cross-training em mulheres obesas elevaram a PA, induziram elevado gasto calórico e impuseram demandas cardiorrespiratórias significativas, classificando essas sessões como de alta intensidade. Essa intensidade está intimamente correlacionada com o gasto energético.
