Abstract Objectives To assess nutritional intake, body composition and sports nutrition knowledge of NCAA Division I female volleyball players. Methods Nutritional intake was assessed using three-day food records. Daily average energy, carbohydrate, protein, fat, and specific vitamins and minerals intakes were analyzed using Food Processor 11.1. These values were compared to the recommendations from the American College of Sports Medicine (ACSM). Sports nutrition knowledge was assessed using an 87-question validated nutrition for sports knowledge questionnaire (NSKQ). Athletes were also asked to state their sources for nutrition knowledge. Body composition was assessed using bioelectrical impedance analysis. Descriptive data (mean ± SD) and Pearson correlation coefficients (r) were calculated using SPSS 26.0 with significance set at P ≤ 0.05. Results Fourteen female volleyball players (age: 19.6 ± 1.3 y, height: 174.9 ± 8.2 cm, weight: 73.2 ± 8.5 kg, BMI: 24.1 ± 2.5 kg/m2; body fat: 25.2 ± 3.4%) completed the study. Athletes’ mean energy intake was 24.7 ± 6.4 kcal/kg BW/day, while carbohydrate, protein and fat intake were 2.9 ± 0.92, 1.3 ± 0.44, and 0.88 ± 0.28 g/kg BW/day, respectively. Vitamin D intake was 137.1 ± 90.7 IU/day and calcium intake was 673.4 ± 352.5 mg/day. Energy and carbohydrate intake were lower than the ACSM recommendations (37–41 kcal/kg BW/day and 6–10 g/kg BW/day, respectively) while fat intake was higher. Protein intake fell within the recommended ranges (1.2–1.7 g/kg BW/day). Additionally, vitamin D and calcium were lower than the recommendations. The average NSKQ score was 45.4 ± 9.6% and was positively associated with weight (r = .738, P = 0.003) and vitamin D intake (r = .587, P = 0.027). Weight management score (51.8 ± 15.4%) was positively associated with weight (r = .676, P = 0.008). Four athletes included a registered dietitian nutritionist (RDN) as a source of nutrition information. In contrast, twelve athletes listed athletic trainers as a source. Conclusions The average NSKQ score suggests that NCAA Division I female volleyball players lack adequate sports nutrition knowledge which may be associated with inadequate energy and nutrient intakes. Athletes may benefit from nutrition education and counseling for improved performance and health from RDNs. Funding Sources There are no funding sources.

Purpose: The purpose of our study was to assess the nutritional strategies of Slovenian national junior swimming team and compare them with recommendations of clinical sports nutrition. Competitive young swimmers namely have increased energy and nutrient needs compared to general adolescents due to frequent and intense training. Despite some physiological differences from adults, adult sports nutrition recommendations for macronutrients apply to them. Further, literature reports iron, calcium, and vitamin D intake as frequently inadequate.Methods: Nutritional strategies of 19 members of Slovenian national junior swimming team were assessed retrospectively through 3-day food and activity diaries, questionnaires, anthropometric data including bioimpedance analysis. Energy availability (EA), macronutrient intake and timing, iron, calcium and vitamin D intakes, hydration, consumption of sports food and dietary supplement use were evaluated.Results: EA in some of male swimmers and in majority of  female swimmers was lower than recommended. Carbohydrate intake was adequate in male swimmers and two thirds of female swimmers. Although average protein intake exceeded the upper recommended limit, some  female swimmers did not meet the lower recommended intake limit. Total fat intake was lower than recommended, with saturated fat intake on the upper recommended level. Calcium and iron intake in male swimmers exceeded recommended values, while female swimmers had lower calcium intake than recommended and some had lower iron intake, too. Vitamin D intake was low in all swimmers. Meal timing was adequate in majority of swimmers, who often reached for dietary supplements, mostly omega 3 fatty acids, multivitamins, and magnesium.Conclusions: Low EA in young competitive swimmers is of concern. More successful, personalised nutrition strategies for young competitive swimmers, focusing on higher energy intake and healthy food choices, would contribute to the preservation of their health and development into top performers.

Vitamin D status positively associates with skeletal muscle mass and function in adolescents. The C-3 alpha epimer of 25-hydroxyvitamin D3 (3-epi-25(OH)D3) is high in infants, yet the potential impacts of 25-hydroxyvitamin D3 (25(OH)D3) and 3-epi-25(OH)D3 on skeletal muscle development are largely unexplored. The objective of this study was (i) to explore how the concentrations of 25(OH)D3 and 3-epi-25(OH)D3 track with body composition (lean mass (LM) and fat mass (FM)) and (ii) to determine the association between 25(OH)D3 and 3-epi-25(OH)D3 in infancy. Healthy breastfed infants (n = 132) were followed from 1 to 12 months of age as part of a vitamin D dose–response study (NCT00381914). Anthropometry and diet were assessed. Body composition was measured with dual-energy X-ray absorptiometry. Plasma 25(OH)D3 and 3-epi-25(OH)D3 concentrations were evaluated using liquid chromatography tandem mass spectrometry. Plasma 25(OH)D3 and 3-epi-25(OH)D3 increased from 1 to 3 months of age and decreased thereafter (p < 0.05). Infants with 25(OH)D3 concentrations above 75 nmol/L did not have a higher LM (g or %; p > 0.273) than those below this cutoff. LM was not associated with 25(OH)D3, whereas LM% was positively associated with 25(OH)D3 (β = 0.03; CI: 0.01 to 0.06; p = 0.006), while accounting for sex, weight-for-age Z-score, protein and fat intake, and age. For FM, the variables accounting for a significant amount of the variation were plasma 25(OH)D3 concentration (β = −2.38; CI: −4.35, −0.41; p = 0.019), weight-for-age Z-score, protein and fat intake, and time. In healthy infants, higher vitamin D status associates with leaner body composition, though the effect is smaller in magnitude relative to growth.

AbstractThis study’s purpose was to evaluate total, regional, and throwing versus non-throwing arm body composition measurements between various positions of NCAA Division I male baseball players using dual X-ray absorptiometry (DXA). Two hundred and one collegiate baseball athletes were measured using DXA. Visceral adipose tissue (VAT), total and regional fat mass (FM), lean mass (LM), and bone mineral density (BMD) were measured. Athletes were separated into: pitchers (n=92), catchers (n=25), outfielders (n=43), and infielders (n=41). ANOVA and Tukey’s honest significant difference assessed total and regional differences between positions. Infielders had significantly (p<0.05) lower total LM than pitchers and outfielders. Additionally, outfielders had significantly lower total FM compared to pitchers and catchers. No significant differences between positions were observed for total BMD and VAT. Pitchers’ and infielders’ throwing arm demonstrated significantly greater total mass, FM, LM, and BMD compared to the non-throwing arm. Further, outfielders’ throwing arm total mass, LM, and BMD were significantly higher vs. the non-throwing arm. Significant differences were observed in total and regional body composition measurements across position, in addition to differences in throwing arm vs. non-throwing arm composition. These measurement values are important to coaches and trainers as normative positional DXA data for collegiate baseball players.

Body composition and power are impactful variables of athletic performance. However, few studies have assessed power and body composition changes from pre-, to mid-, to end-of-season in American Football linebackers. The purpose of this study was to determine how power and body composition respond to a competitive season in Division I Football Championship Series (FCS) American football linebackers. Participants (n=9; Age=19.7 ± 1.5 years; Weight=101.5±11.6 kg; Height=183.3±5.2 cm; [Body Fat percent (BF %) =21.31 ± 6.02%)] performed a Dual-Energy X-ray Absorptiometry (DXA) scan, and power was assessed via three vertical jumps and squat jumps at 40, 60, 80, and 100 kg at three time points: a) 1 week prior to their regular season, b) 2 days after the bye week in the middle of the season, and c) 1 week prior to the completion of the season. An Analysis of Variance (ANOVA) revealed no significant differences (p ≤ 0.05) in power or body composition. These results support past research, indicating power and body composition can be maintained throughout a competitive season. However, more research is needed to determine the optimal programming methods to maintain or improve athletic performance via optimization of body composition and power during a competitive season.
