Fat-free mass (FFM), serum testosterone, cortisol, and SHBG did not change significantly. Caion and pH decreased (p ≤ 0.05) only in HWR (3.1 ± 2.8 % and 0.8 ± 0.8 %, respectively), whereas HCO3- declined (p ≤ 0.05) in both groups by 19.3 ± 6.2 % in HWR and by 13.1 ± 8.5 % in LWR. The counter-movement jump and 20-m sprint time improved consistently (p ≤ 0.05) only in HWR, by 2.6 ± 2.5 cm and 0.04 ± 0.04 s, respectively. Finally, athletes with a fat percentage 10% or over at the baseline were able to preserve FFM. In conclusion, altered acid-base balance but improved weight bearing power performance was observed without negative consequences on serum hormones and FFM after a four-week weight reduction of 0.5 kg / week achieved via reduced carbohydrate but maintained high protein intake. Various studies examining the impact of energy restriction in active individuals have been conducted (Karila et al., 2008 Pikosky et al., 2008 Morton et al., 2010 Wilson et al., 2012 Pasiakos et al., 2013 Rhyu and Cho, 2014 Huovinen et al., 2015). While most of the studies revealed that energy restriction was associated with a significant lean body mass loss (Karila et al., 2008 Pikosky et al., 2008 Morton et al., 2010 Pasiakos et al., 2013 Rhyu and Cho, 2014), ranging from 34% (∼-1200 kcal/day Morton et al., 2010) to 84% (∼-2500 kcal/day Karila et al., 2008) of the total mass lost per week, some studies reported no significant lean body mass change during energy restriction (Huovinen et al., 2015 Wilson et al., 2015). Since all of these studies differ in total energy deficit, protein intake, sleep duration, baseline body fat, and type of physical activity performed, which are all known to significantly influence lean body mass change (Heymsfield et al., 2011), the exact reasons for the inherent interstudy differences remain unclear.īackground: It is often advised to ensure a high protein intake during energy-restricted diets. However, it is unclear whether a high protein intake is able to maintain muscle mass and contractility in the absence of resistance training. Materials and Methods: After 1 week of body mass maintenance (45 kcal/kg), 28 male college students not performing resistance training were randomized to either the energy-restricted (ER, 30 kcal/kg, n = 14) or the eucaloric control group (CG, 45 kcal/kg, n = 14) for 6 weeks. Both groups had their protein intake matched at 2.8 g/kg fat-free-mass and continued their habitual training throughout the study. Body composition was assessed weekly using multifrequency bioelectrical impedance analysis. rectus femoris were examined with Tensiomyography and MyotonPRO at weeks 1, 3, and 5 along with sleep (PSQI) and mood (POMS). Results: The ER group revealed greater reductions in body mass (Δ -3.22 kg vs. ![]() 116) decreased significantly in the ER group and the CG, respectively.ĭiscussion: The present data show that a high-protein intake alone was not able to prevent lean mass loss associated with a 6-week moderate energy restriction in college students. Notably, it is unknown whether protein intake at 2.8 g/kg fat-free-mass prevented larger decreases in lean body mass. Muscle contractility was not negatively altered by this form of energy restriction. Whether these advantages are due to the high-protein intake cannot be clarified and warrants further study. Although vigor was negatively affected in both groups, other mood parameters did not change. With respect to the studies' abstracts, 51 of the reviewed studies were chosen to be potentially relevant for data analysis. ![]() The full texts of these articles were then screened 36 of these studies (Greene et al.
