Dietary Intake of Young Male Ice Hockey Players 10–13 Years of Age during a Week-Long Hockey Camp

Abstract

This study recorded the dietary intakes of young male ice hockey players (10–13 year (yr)) for 3 consecutive days while participating in a 5-day summer hockey camp. Players were categorized as older children (OC, n = 10; 10.7 ± 0.2 yr; 37.1 ± 1.5 kg; 147.9 ± 2.1 cm) and young adolescents (YA, n = 10; 12.9 ± 0.1 yr; 45.2 ± 1.5 kg; 157.0 ± 2.4 cm). Players consumed their usual daily intakes. Parents recorded food intake in the mornings and evenings, while the researchers recorded food intake at camp. Energy intake was higher in both groups when compared to data for age-matched young Canadian (CDN) males (OC, 2967 ± 211 vs. 2000 kcal/day; YA, 2773 ± 91 vs. 2250 kcal/day). Carbohydrate (CHO) (OC, 11.2 ± 0.8 vs. YO, 8.9 ± 0.5 g/kg body mass/day) and protein (OC, 3.2 ± 0.3; YO, 2.4 ± 0.1 g/kg/day) intakes were higher than reported for young CDN males (CHO, 3.6 and protein, 1.0 g/kg/day) and were within the Acceptable Macronutrient Distribution Range (AMDR; CHO, 56 ± 2.3; 57.4 ± 0.8%; protein, 16.1 ± 1.0; 15.7 ± 0.7%). Fat intake was also within the AMDR in both groups (OC, 29.8 ± 1.6%; YA, 28.3 ± 1.0%). Micronutrient intake was adequate except for Vitamin D intakes that were below the recommended 15 ug/day at 6.3 ± 0.7 (OC) and 5.0 ± 1.5 ug/day (YA). In summary, energy and macronutrient intakes of the OC (10–11 yr) and YA (12–13 yr) players were high and well above the age matched CDN norms. The older children had higher energy intakes/kg body mass than the young adolescents. Higher energy intakes allowed for micronutrients intakes to be met in these young active males, except for vitamin D intake.

Artificial Intelligence-Based Soccer Sports Training Function Extraction: Application of Improved Genetic Algorithm to Soccer Training Path Planning

“…For example, if a team's star player is injured on the field of play, how the entire team will reformulate its tactics to play the game is something that both coaches and players need to be aware of. Artificial intelligence expert Touhill stated that the purpose of applying artificial intelligence to soccer is not to replace the coach, but to assist the coach's coaching by using intelligent technology to process data that cannot be handled manually, so as to better find solutions to problems [3].…”

Cross-Sectional Study of the Anthropometric Profile and Nutrient Status of Elite Female Ice Hockey Players: Differences by Play Position

“…The proportion of energy obtained from lipids and proteins notably exceeds the proportions recommended for the Spanish adult population [42] and those reported in other studies with female ice hockey players [29] or female athletes in general [56], which could probably explain the level of the sample not following a structured dietary plan. Because during an ice hockey match muscle glycogen declines between 38 and 88%, the low proportion of carbohydrates could affect physical performance [1,57].…”

“…This muscle glycogen should be readily disposable for its primary sports need, which is to maintain performance and offset fatigue. Carbohydrate is the most important fuel for ice hockey players, with daily intakes observed in male adolescents of ~9-11 g/kg [29] and ~2.5-7.6 g/kg in varsity females [3].…”

“…This muscle glycogen should be readily disposable for its primary sports need, which is to maintain performance and offset fatigue. Carbohydrate is the most important fuel for ice hockey players, with daily intakes observed in male adolescents of ~9–11 g/kg [ 29 ] and ~2.5–7.6 g/kg in varsity females [ 3 ]. Women have lower whole-body sweat rates and sweat sodium concentrations than men, but in most cases, these differences are attributed to lower absolute workloads.…”

“…During the luteal phase, there is an increase in the core body temperature threshold for the onset of sweating, but there are no differences in whole-body sweat rate across the phases of the menstrual cycle. Female hockey players should drink enough fluid during exercise to avoid significant hypohydration, as 2% body mass loss is associated with performance decrements in women, and should achieve an adequate intake of 2 L per day or 20.9 mL every 15 min [ 3 , 7 , 21 , 22 , 23 , 24 , 25 , 26 , 27 , 28 , 29 ].…”
