Impact of a 6-week non-energy-restricted ketogenic diet on physical fitness, body composition and biochemical parameters in healthy adults

Introduction: This study aimed to clarify whether 1 year of vitamin D3 supplementation has a direct effect on body composition and physical fitness in healthy adults. Methods: Ninety-five participants randomly received either 420 IU vitamin D3 per day (n = 48) or placebo (n = 47) in a double-blind manner for 1 year. Lean body mass and percentage body fat were determined. Physical fitness including hand grip strength, leg extension power and cardiorespiratory fitness (CRF) were assessed. Serum 25-hydroxyvitamin D (25[OH]D) and 1,25-dihydroxyvitamin D (1,25[OH]2D) concentrations were assessed using ELISA kits. Results: Serum 25(OH)D and (1,25[OH]2D) concentrations significantly increased by approximately 11.2 ± 9.2 ng/mL (pinteraction <0.001)and 7.0 ± 7.8 pg/mL (pinteraction <0.001) after 1 year of vitamin D3 supplementation respectively. Lean body mass significantly increased from 43.8 ± 9.6 to 44.3 ± 9.8 kg in vitamin D group, while no change was observed in placebo group (from 42.6 ± 8.9 to 42.4± 8.9 kg) after 1 year intervention. Furthermore, no treatment effects on other indicators of body composition and physical fitness were observed. Conclusions:One year of vitamin D supplementation effectively improves lean body mass, but not muscle strength and CRF in healthy adults.

Objective: the aim of our study was to assess the effect of a physical activity that uses active video games in body composition, physical fitness, cardiovascular and biochemical parameters with sedentary adolescents. Methods: a non-controlled clinical trial design with a convenience sample of adolescents, separately, from ages ten to 17, of both genders. The intervention protocol consisted of physical activity with active video games (AVG), lasting two months, in 24 sessions, evolving into three levels (basic, intermediate and advanced) according to the maximum heart rate of the individuals. The adolescents’ body composition, physical fitness, cardiovascular and biochemical parameters were assessed. Data analysis was performed with a 95% confidence interval. Results: among the 14 adolescents that completed the physical training, we observed a improvement of muscle resistance (Δ= 8.26; p= 0.02) and decrease in post-exercise heart rate and systolic blood pressure (p< 0.01). However, were found a non-significant decrease in body fat percentage (Δ= -3.83; p= 0.24) and strength (Δ= 4.26; p= 0.57). A high level of satisfaction with the proposed activity was identified. Conclusion: a physical activity program based on AVG can reduce cardiovascular risk factors and improve muscle resistance in sedentary adolescents.
