Iron status determined changes in health measures induced by nordic walking with time-restricted eating in older adults- a randomised trial.

Background And Aims: This study evaluated whether stored iron determines the adaptive response induced by Nordic walking (NW) training combined with 10 hours' time-restricted eating (TRE) in older adults.

Trial Design And Methods: Twenty-four participants underwent 12-week NW training supported by 10 h of TRE. The group was divided due to baseline ferritin concentration low < 75 ng/ml (LF) and high level ≥ 75 ng/ml (HF).
