| Abstract |
We evaluated dietary intake and body composition of child and adolescent rink-hockey players and controls. Seventy-two male rink-hockey players (38 children and 34 adolescents) and 79 male controls (43 children and 36 adolescents) were evaluated in order to collect training data, detailed dietary intake and body composition. Rink-hockey players presented significantly lower body fat (BF) and higher fat-free mass (FFM) than controls. Mean intakes of carbohydrate and protein were considered to be adequate, but mean intakes of fat were above the recommended levels in athletes. Significant differences were found for energy intake (EI) and exercise energy expenditure (EEE) between athletes and controls (P < 0.05), resulting in some cases of low energy availability in rink-hockey players. Significant group differences (P < 0.05) were also observed for vitamins and mineral intakes in child and adolescent rink-hockey players due to higher mean intakes in control groups. Low intakes of vitamins D, E and K, calcium, iron, boron and magnesium were reported in athletes, with exception for thiamine (P = 0.449), riboflavin (P = 0.246), pantothenic acid (P = 0.065), magnesium (P = 0.061) and phosphorus (P = 0.051) in children and for niacin (P = 0.652), vitamin D (P = 0.406) and zinc (P = 0.783) in adolescents. Nutritional deficiencies in macronutrients and micronutrients observed in very young rink-hockey players can impair their growth and development with negative consequences upon athletic performance. What is Known: • Adequate dietary intake is an important resource for athletes' short- and long-term health, performance and recovery. • There are no published studies in rink-hockey players' energy availability. What is New: • This study provides the first data on significant differences in energy intake between very young athletes and controls, resulting in low energy availability in rink-hockey players. • Mean intakes of fat were above the recommended levels, and micronutrients intakes were inappropriate in athletes with consequences for their health and performance. |

Attention Score in Context
This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 19 November 2016.
All research outputs
#18,482,034
of 22,901,818 outputs
Outputs from European Journal of Pediatrics
#3,128
of 3,730 outputs
Outputs of similar age
#234,523
of 309,583 outputs
Outputs of similar age from European Journal of Pediatrics
#35
of 44 outputs
Altmetric has tracked 22,901,818 research outputs across all sources so far. This one is in the 11th percentile – i.e., 11% of other outputs scored the same or lower than it.
So far Altmetric has tracked 3,730 research outputs from this source. They typically receive more attention than average, with a mean Attention Score of 8.7. This one is in the 7th percentile – i.e., 7% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 309,583 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 13th percentile – i.e., 13% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 44 others from the same source and published within six weeks on either side of this one. This one is in the 6th percentile – i.e., 6% of its contemporaries scored the same or lower than it.
