简要总结
The objective of this study is to compare the body composition and physical performance effects of HIIT, with or without intermittent fasting intervention in active women. Fourteen active normal weight women aged 18-35 participated in the study. The effects of 2x8 weeks without (HIIT) or with (HIIT+IF) intermittent fasting caloric restriction (20% reduction in weekly energy intake) on body composition and performance (Hand-grip strength, Counter movement jump, Wingate Anaerobic 30 s Cycling Test), were compared. There were two weeks in between both phases when they did not perform the scheduled activity, so as not to alter the experimental phase.

研究组 & 干预措施
PARTICIPANTS
A single-group crossover design was used to compare the effects of 2x8 weeks of high-intensity interval training without (HIIT) or with (HIIT+IF) intermittent fasting caloric restriction (20% reduction in weekly energy intake) on body composition and performance. There were two weeks in the middle of both phases in which they did not carry out programmed activity, in order not to alter the experimental phase.
干预措施: Intensity interval training (HIIT) (Behavioral)

结局指标
主要结局
Counter movement jump (CMJ)
时间窗: 16 weeks
In the CMJ test, the participants performed a maximum vertical jump starting from a standing position with arm swing not allowed.
Residual mass
时间窗: 16 weeks
Body composition masses were estimated using validated equations. Residual mass was obtained from the difference between fat mass and muscle mass.
Muscle mass
时间窗: 16 weeks
Body composition masses were estimated using validated equations. Lee's equation to estimate muscle mass.
Body Mass
时间窗: 16 weeks
It was performed using a digital scale with 0,1kg accuracy (Tanita BC-545, Tokyo, Japan).
Hand-grip strength
时间窗: 16 weeks
Hand-grip strength test was performed as an indicator of overall strength.
Fat mass
时间窗: 16 weeks
Body composition masses were estimated using validated equations. Carter's equation was used to estimate fat mass.
Wingate Anaerobic 30 s Cycling Test
时间窗: 16 weeks
Wingate Anaerobic 30 s Cycling Test with a validated cycloergometer (Monark 894E, Vansbro, Sweden).
