RESULTS: Eighteen young adults (age: 23 ± 2.0 yrs., body mass index: 23.5 ± 2.8 kg·m-2) were recruited and participated in the supervised intervention. The discrete component open circuit spirometry system was used to measure oxygen consumption (VO2), and Frayne\'s equation was used to determine the FOR plus FORmax. ANOVA was used to determine pre/post-intervention differences in FORmax. The FORmax for the TRF16 + HIIT intervention was significantly higher than the TRF12 (mean difference = 0.099 g·min-1, p = 0.011, 95% CI 0.017 to 0.180) and TRF16 fast alone (mean difference = 0.093 g·min-1, p = 0.002, 95% CI 0.027 to 0.159). The FORmax for TRF12 + HIIT intervention was significantly higher than the TRF12 fast alone (mean difference = 0.070 g·min-1, p = 0.023, 95% CI 0.007 to 0.134). The TRF16 + HIIT intervention was also significantly higher than the TRF12 fast alone (mean difference = 0.099 g·min-1, p = 0.011, 95% CI 0.017 to 0.180).
CONCLUSIONS: This study contributes to the ever-growing body of literature on the acute effects of TRF and PA on young adult males and females. The findings suggest that the TRF16 + HIIT PA intervention results in the highest FORmax.
BACKGROUND: Retrospective Registration ISRCTN # 10076373 (October 6, 2023).
结果:18名年轻人(年龄:23±2.0岁。,身体质量指数:23.5±2.8kg·m-2)被招募并参与监督干预。分立元件开路肺活量测定系统用于测量耗氧量(VO2),和Frayne的方程被用来确定FOR+FORmax。方差分析用于确定干预前/后FORmax的差异。TRF16+HIIT干预的FORmax显著高于TRF12(平均差=0.099g·min-1,p=0.011,95%CI0.017~0.180)和单独TRF16Fast(平均差=0.093g·min-1,p=0.002,95%CI0.027~0.159)。TRF12+HIIT干预的FORmax显著高于单独TRF12快速干预(平均差=0.070g·min-1,p=0.023,95%CI0.007~0.134)。TRF16+HIIT干预也显著高于单独的TRF12(平均差异=0.099g·min-1,p=0.011,95%CI0.017~0.180)。
结论:这项研究有助于不断增加的关于TRF和PA对年轻成年男性和女性的急性影响的文献。研究结果表明,TRF16+HIITPA干预导致最高的FORmax。
