Study Details

Study Description

Brief Summary

The purpose of this study is to investigate the effects of 4 weeks of carbohydrate deprivation (through a ketogenic diet) on hypertrophy signalling after a single bout of exercise in healthy trained male subjects, and the impact on body composition, muscle strength, and blood parameters.

Arms and Interventions

Arm Intervention/Treatment
Experimental: ketogenic diet

Participants will perform a single exercise bout after 4 weeks of resistance training combined with a ketogenic diet (KD group).

Other: resistance training
All participants perform a four-day resistance training aimed to stimulate a hypertrophic response.

Other: ketogenic diet
Subjects allocated to the ketogenic diet arm (KD group) consume less than 50 g of carbohydrates per day.

Active Comparator: western diet

Participants will perform a single exercise bout after 4 weeks of resistance training combined with a western diet (WD group).

Other: resistance training
All participants perform a four-day resistance training aimed to stimulate a hypertrophic response.

Other: western diet
Subjects allocated to the western diet arm (WD group) consume a standard diet based on 55% of their daily calories from carbohydrates.

Outcome Measures

Primary Outcome Measures

  1. mammalian target of rapamycin (mTOR) signalling [Change from baseline to 4 weeks]

    Measurement of the change in muscle protein anabolic signalling pathway in response to a single bout of resistance exercise by western blot analysis.

Secondary Outcome Measures

  1. Skeletal muscle mass [Change from baseline to 4 weeks]

    Measurement of the change in kilograms of muscle mass via Dexa
