Abstract
Whereas beetroot juice (BJ) supplementation is shown to increase physical performance in endurance activities, its benefits in team sports has been barely studied. In this randomized placebo-controlled study, we investigated the effects of BJ acute supplementation in improving neuromuscular performance and physical match activity in basketball. Ten young male competitive basketball players aged 15-16 years received 140 mL of BJ or placebo (PLA) on two separated days in a balanced cross-over design. Testing sessions comprised a neuromuscular test battery consisting of a countermovement jump (CMJ), isometric handgrip strength, 10-m/20-m sprint and agility T-test, followed by a 40-minute simulated basketball match. Physical match activity (distances, speeds, accelerations, and decelerations) was monitored using an inertial tracking system (Wimu ProTM) Results revealed no significant effects of BJ on CMJ (p = 0.304, ES = 0.13), isometric handgrip strength (p = 0.777, ES = 0.06), 10-m (p = 0.820, ES = 0.10), and 20-m sprint (p = 0.540, ES = 0.13), agility T-test (p = 0.979, ES ≤ 0.01) and any physical match demands (p > 0.151, ES = 0.13-0.48). Acute moderate doses of BJ (12.8 mmol of NO3-) was not effective in improving neuromuscular performance (jump height, isometric handgrip strength, sprint, and agility) or physical match requirements in young trained basketball players the day of the competition.

Abstract
Vitamin D may play a role in performance and injury risk, yet the required supplementation dosage for collegiate athletes is unclear. The objective of this study was to define the dosage of vitamin D3 supplementation required to beneficially affect serum 25-hydroxyvitamin D (25(OH)D) among a sample of collegiate basketball athletes. This was a quasi-experimental trial, participants were allocated to one of three groups of vitamin D3 daily at the beginning of pre-season training and dependent upon their baseline vitamin D status as follows: insufficient (<75 nmol/L) to 10,000 IU, sufficient (75-125 nmol/L) to 5000 IU and optimal (>125 nmol/L) to no supplementation. Follow-up assessments were completed ~ 5 months later in post season. The majority (n = 13) were allocated to 10,000 IU vs. n = 5 to 5000 IU and n = 2 to no supplementation. The 10,000 IU group showed the greatest change (35.0 ± 27.0 nmol/L) vs. the 5000 IU group (-9.3 ± 9.6 nmol/L) and no supplementation group (-41.6 ± 11.7 nmol/L, p < 0.01). Only 1 participant reached optimal status in the 10,000 IU group. In conclusion, a daily dosage of 10,000 IU vitamin D3 supplementation mitigated the high prevalence of vitamin D deficiency among collegiate basketball players but was insufficient for all to reach sufficient levels.

Abstract
INTRODUCTION in relation to the student population, their class schedules, hours of study, budget shortages, among others, do not allow them to have good eating habits and sedentary ago. Within this context are the sports teams, which must deal with the above. OBJECTIVE knowing the nutritional status of a group of college basketball players (BU) by anthropometric and biochemical parameters. METHODS the research provides a non-experimental, descriptive, transversal, with a quantitative approach The sample was selected on a non-probabilistic approach. which included 12 players design. Anthropometric parameters for body mass index (BMI), somatotype and body composition was assessed. For biochemical glucose, triglycerides and cholesterol. RESULTS have a BMI of 24.6 (kg/m2), are classified as endomesomorfas (5,5-4,3-1,2) have a fat mass 39.9% and 37.8% of muscle mass, glucose values are 68.7 (mg/dl), triglycerides 128 (mg/dl) and 189 cholesterol (mg/dl). CONCLUSION the BU have normal values for BMI and biochemical parameters, but dig deeper greater amount of adipose tissue is found as reported by body composition and somatotype, a situation that could be related to poor eating habits, however is required further study to reach a categorical conclusion.
