Summary

The therapeutic use of caloric restriction and intermittent fasting (IF) protocols improves life span and health related quality of life. The effects of fasting protocols on athletic performance and training adaptations have been primarily studied in athletes undergoing the Ramadan IF protocol or in athletes willing to decrease body fat, while maintaining or increasing lean body mass. Data from these studies are somewhat conflicting and unclear. Moreover, the effects of IF on muscular strength, as well as in aerobic and anaerobic capacity remain largely unknown. Anecdotal evidence from experienced participants in strength, power and endurance training or sports, indicates an increased ability to acutely display higher levels of work capacity in the fasted vs. fed state. The goal of this project is to determine the effects of 4 wks of IF on neuromuscular performance, aerobic and anaerobic capacity of well-trained young adults.

Experimental Group

This 3-year project will include two groups of participants: 1) young men accustomed to resistance training (study #1) and 2) young men accustomed to endurance training (study #2). Inclusion will be limited to healthy participants (i.e. nonsmokers, normotensive with systolic and diastolic values \<135/85 mmHg, non-obese, non-medicated, and free of any known disease as assessed by medical history) (Pickering, Hall et al. 2005). Month 1-3 will focus on literature review and month 4 to 8 will address experimental settings preparation and selection of participants to include in each study. Testing and data collection will be scheduled for months 9-14 and 13-18 (study # 1 and 2 related testing, respectively). Data processing, analysis and presentation will occur from month 21 to 33. All participants will read and sign an informed consent document with the description of the testing procedures. The Faculty's ethical committee will be asked to approve this document before testing.
