Clinical Trial Summary

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.

Outcome

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