Adolescent runners’ mean dailyenergy intake (2002 kcal/day) also matched previous reports among Japanese and Kenyanadolescent endurance runners, exhibiting mean energy intakes of 2340 kcal/day and 2028kcal/day, respectively (Iwasaki et al., 2019; Muia et al., 2016).
So that means it's the same in very different cultures, that's really interesting
This finding is consistent with results from Shriver et al., among asample of collegiate endurance athletes, which also reported that only 9% of athletes weremeeting their estimated energy needs (Shriver et al., 2013).
FIND THIS STUDY (LOOK AT REFERENCES)
Mean energy intake of male and female runners fell below the minimum energyrequirements needed to ensure proper growth and bodily functions for adolescents aged 15-18
Scary but unsurprising, I wonder if it's because they underestimate their needs?
