Physical Activity Levels to Estimate the Energy Requirement of Adolescent Athletes
Abstract
Adequate energy intake in adolescent athletes is considered important. Total energy expenditure (TEE) can be calculated from resting energy expenditure (REE) and physical activity level (PAL). However, validated PAL recommendations are available for adult athletes only. Purpose was to comprise physical activity data in adolescent athletes and to establish PAL recommendations for this population. In 64 competitive athletes (15.3 ± 1.5yr, 20.5 ± 2.0kg/m 2) and 14 controls (15.1 ± 1.1yr, 21 ± 2.1kg/m 2) TEE was calculated using 7-day activity protocols validated against doubly-labeled water. REE was estimated by Schofield-HW equation, and PAL was calculated as TEE:REE. Observed PAL in adolescent athletes (1.90 ± 0.35) did not differ compared with controls (1.84 ± 0.32, p = .582) and was lower than recommended for adult athletes by the WHO. In conclusion, applicability of PAL values recommended for adult athletes to estimate energy requirements in adolescent athletes must be questioned. Instead, a PAL range of 1.75–2.05 is suggested.

“Research assessing physical activity levels among adolescent athletes aged 12–18 years found that the mean PAL in this population was significantly lower than adult-based recommendations [36].”

In the citing paper
“While group estimates of energy expenditure in adolescent athletes are available (i.e., males ~ 3640 ± 830, females ~ 3100 ± 720 kcal/day [17]), the energy expenditure of individual adolescent athletes may vary considerably.”
From Youth Athlete Development and Nutrition (2021) · cites this paper as [17]
In the citing paper
“Although group estimates of energy expenditure in adolescent athletes have been reported (i.e., males ∼3,640 ± 830 kcal/day and females ∼3,100 ± 720 kcal/day; Carlsohn et al., 2011), it is difficult to define the individual energy requirements of an adolescent athlete with precision”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
