AI Article Synopsis
- - The study examines energy availability (EA) and its impact on hormonal profiles in East African endurance athletes, focusing on both male and female competitors.
- - Results showed that athletes with low EA had higher levels of cortisol and insulin but lower levels of growth hormone compared to those with high EA, indicating significant hormonal differences based on energy status.
- - The findings suggest that the hormonal responses to energy availability in East African athletes are somewhat similar to those observed in White populations, but there are unique aspects that warrant further exploration.
Article Abstract
Background: Energy availability (EA) and relative energy deficiency in sport (RED-S) are understudied in East African endurance athletes, both females (F) and males (M). This study assessed the metabolic hormonal profiles of such athletes relative to their EA status.
Methods: Forty athletes (F=16, M=24) had their EA status, training, maximal oxygen uptake, and resting blood samples assessed using standard research practices. Subjects were stratified into two groups, high EA (HiEA) and low EA (LoEA) based on combined median value.
Results: Cortisol (P=0.034) and insulin (P=0.044) were significantly elevated in the LoEA group, while growth hormone (P=0.045) was significantly suppressed; and, prolactin (P=0.078) trended towards suppression, respectively compared to the HiEA group. All other hormonal comparison were non-significant.
Conclusions: Metabolic hormonal profiles of female and male African distance runners are affected by their EA status. Aspects of these alterations agree in part with published findings based upon White populations, although some differences exist and need further investigation.
