Filter by:Background: Proper nutrition is essential for sports performance. Quinoa is a gluten-free grain rich in macronutrients such as protein, polysaccharides, and fatty acids and consists of many phytochemicals such as carotenoids, flavonoids, saponins, fiber, vitamins, and minerals. Phytochemicals in quinoa act as antioxidant and anti-inflammatory. This will protect against several oxidative stress related diseases. Objective: Investigate the effect of 50 g of quinoa for four weeks on muscle strength, VO2max and athletic performance among adolescent athletes. Study design: A Double blinded randomized control trial with pre-test and post-test design. Methods :32 subjects will be included in this trial. Subjects will be divided randomly into control and experimental group with a 1:1 ratio; the experimental group will receive two cookies that contain 50 grams of quinoa; the control group will receive the same two cookies that but without quinoa. Strength will be assessed by using hand-held dynamometer (HHD). Maximum oxygen uptake capacity (Vo2max) will be assessed by Queen's College step test (QCT). And for evaluating performance: standing long jump test, ball throw test, and agility T-test will be used. Subjects will be asked to take the cookies 1-4 hours before bedtime daily during the study period. Statistical Analysis: Shapiro wilk test will be performed to check the normality of the data and Levenes test will be performed to check homogeneity of variance. Cohen's d will be used to check the effect size. The level of significance is set to p ≤ 0.05.
The purpose of this study was to verify the effect of chronic 12-week high-dose Colostrum Bovinum (COL) and placebo (PLA) supplementation on immunological, hematological and biochemical markers, as well as physical capacity and discipline-specific exercise performance in endurance athletes, in a randomized, double-blind, placebo-controlled crossover trial.
Athlete nutrition is becoming an increasingly important factor on the path to achieving top results. Nutrients such as soluble fiber can alter the intestinal microbiota, resulting in metabolites with a positive effect on metabolism. Thus, the fibers become available, an additional source of energy to the host, have an anti-stress effect and delay the feeling of fatigue. The primary goal of the study is to determine the impact of soluble dietary fiber on increasing athletic efficiency, the secondary goal is to determine the impact of fiber on delaying fatigue. Subjects will be randomly divided into experimental and control group. The sample of variables will consist of genome microbiota genome sequencing data, measures to assess morphological characteristics, lower extremity explosive strength tests, and cardiovascular endurance. The statistical package SPSS will be used for data processing. The expected scientific contribution of this research is to expand the scientific knowledge about the importance of dietary fiber in the diet of athletes with the aim of improving sports performance.
The objective of this testing is to gain a better understanding of sports nutrition knowledge in high school athletes and their influencers (coaches, strength and conditioning coaches, athletic therapists, dieticians). Since the sports nutrition knowledge of the high school athletes will be limited, nutrition behaviors will be assessed to infer knowledge of sports nutrition. The secondary objective is to determine the primary sources of nutrition knowledge in these populations.
Introduction: The dehydration is a very common problem that is often not identified. The pediatric population is more susceptible to dehydration due to its physiological characteristics. Proper hydration is crucial for health since any degree of dehydration causes a reduction in physical and mental work capacity, hence the importance of preventing it by considering the type of drink. There are multiple beverage options, including industrial oral electrolytes (OE), on the other hand, coconut water (CW) has been studied as a natural alternative beverage with characteristics that can help maintain a state of euhydration. Objective: To determine if AC has a greater effect on hydration status than OE in adolescents who perform physical exercise. Material and methods: RCT, double blind. 34 subjects aged 13.02 ± 1.08 years were selected, assigned to treatment with either OE (Electrolit®) or CW. They received a weekly physical exercise session (4 weeks). Hydration was personalized (ml x kilograms of weight) and hydration was evaluated by Urine Specific Gravity (USG), Total Body Water (TBW) by bioimpedance and changes in body mass. Results: There were no significant differences in hydration in the first 3 exercise sessions (p>0.05), however, in the last session there was a significant difference between treatments (p=0.003). Conclusion: AC and OE have the same effect on hydration levels in adolescents who perform physical exercise.
The study aims at assessing the relation between caffeine (CAF) and paraxanthine (PAX) kinetics after acute ingestion of caffeine (3 mg/kg body mass) in the form or mono- or multi-ingredient preparations and CrossFit®-specific performance or selected indicators of psychophysiological state. Blood indicators of muscle damage/recovery, acid-base balance and electrolytes levels will be evaluated. The impact of genetic variations in the polymorphisms rs5751876 in ADORA2A gene and rs762551 in CYP1A2 on CAF/PAX kinetics will be considered.
The study aims at assessing the influence of β-hydroxy-β-methylbutyrate (HMB) free acid supplementation (90 mg/kg of fat free body mass/day) supplemented for 21 days on protein kinases activity and selected hormones levels, and subsequent improvements in muscle protein synthesis, lean body mass content and aerobic capacity.
A novel patent-pending "Prodovite®" VMP35 Multi-Nutrient-Complex (MNC), a vitamin, mineral, and phytonutrient encapsulated liquid formulation, was prepared using a novel proprietary SK713 SLP multi-lamellar non-GMO phospholipid nutrient absorption/delivery technology in a state-of-the-art multistep cGMP and NSF-certified manufacturing facility. This developmental technology is biodegradable and biocompatible. Preliminary study in our laboratory demonstrated the efficacy of "Prodovite®" VMP35 in Sports Nutrition. The investigators hypothesize that "Prodovite®" VMP35 supplement will enhance strength, endurance, and athletic performance; and improve energy output, lean-body muscle mass, increase exercise tolerance, recovery, and improve anabolic parameters in healthy human subjects. The aim of this randomized double-blind placebo-controlled study is to evaluate the effect of oral supplementation of "Prodovite®" VMP35 on the parameters. The investigators hypothesize that "Prodovite®" VMP35 supplementation will enhance all the athletic parameters and improve blood chemistry parameters in healthy human subjects. Accordingly, 150 healthy male and female subjects will be randomly assigned to receive either "Prodovite®" VMP35 or placebo in the form of single dose sealed containers for 90 consecutive days and muscle strength, endurance, speed, anabolic/catabolic parameters and muscle mass will be evaluated by dual energy X-ray absorptiometry (DEXA), hand-grip strength test, cycle ergometer test, spirometer assessment and assay of Blood chemistry and serum biomarkers will be evaluated before and after intervention.
The proteins of human breast milk are the most important endocrine signaling system that promotes neonatal growth by increasing the release of insulin, insulin-like growth factor-1 (IGF-1), and the leucine-mediated mammalian target of rapamycin complex 1- (mTORC1) signaling of pancreatic β-cells. Remarkably, the branched-chain amino acids (BCAAs) leucine, isoleucine, and valine are involved in the growth-promoting effects of milk, protein biosynthesis, and metabolism because they physiologically stimulate insulin secretion The present study sought to investigate the effects of the combination of whey protein and casein in the ratio of 80:20 ("whey protein: casein" or "casein: whey protein") as breast milk proportion on the peak and the period of the permanence of branched-chain amino acids in the blood circulation, final metabolites of protein metabolism and delayed onset muscle soreness (DOMS) after a single bout of fasting or a resistance exercise session.
The study aims at assessing the influence of β-hydroxy-β-methylbutyrate (HMB) supplementation (4.0 g/day) supplemented for 7 days in a group of speed-strength trained individuals on lower-body strength performance, selected muscle histological, molecular and blood markers of muscle recovery in response to resistance exercise-induced muscle damage.
