Fig. 4From: Iron status determined changes in health measures induced by nordic walking with time-restricted eating in older adults– a randomised trialBeneficial effects of time-restricted eating (TRE) combined with Nordic Walking training (NW) are related to baseline ferritin concentration. During 12 weeks of NW + TRE, changes in ferritin, body weight, skeletal muscle mass, and fat mass were significantly higher in participants with baseline ferritin above 75 ng/ml (HF) compared to those with ferritin lower than 75 ng/ml (LF). The changes in blood glucose and HbA1c were similar in both groups (↓) -indicates that changes were significant after the intervention in all subjects, (↓↓ or ↑↑)- Indicates that the changes significantly differed from those observed in participants with serum ferritin lower than 75 ng/ml.
