Low energy availability in female athletes: From the lab to the field
European Journal of Sport Science, 2021 ABSTRACTDecades of laboratory research have shown impairments to several body systems after only 4–5 days of strictly controlled consistent low energy availability (LEA); where energy availability (EA) = Energy Intake (EI) − Exercise Energy Expenditure (EEE)/Fat‐Free Mass.

Unexpected patterns of plastic energy allocation in stochastic environments [PDF]
, 2008 When environmental conditions vary stochastically, individuals accrue fitness benefits by exhibiting phenotypic plasticity. Such benefits may be counterbalanced by costs of plasticity that increase with the exhibited degree of plasticity.

Low energy availability and low body fat of female gymnasts before an international competition [PDF]
European Journal of Sport Science, 2014 AbstractThe purpose of the present study was to evaluate dietary intake and body composition of elite rhythmic gymnastics (RG) athletes prior to a competition event. Sixty‐seven rhythmic gymnasts (18.7 ± 2.9 years old) of high performance level, with 36.6 ± 7.6 h of training/week were evaluated in order to collect training and competition data, medical

Revealing the structure of land plant photosystem II: the journey from negative‐stain EM to cryo‐EM
FEBS Letters, EarlyView.Advances in cryo‐EM have revealed the detailed structure of Photosystem II, a key protein complex driving photosynthesis. This review traces the journey from early low‐resolution images to high‐resolution models, highlighting how these discoveries deepen our understanding of light harvesting and energy conversion in plants.
