Methods: A total of 53 self-reliant elderly persons, 40 of whom were women (age 69.4±4.7 years old; BMI 31.2±4.3 kg-m2) and 13 of whom were men (age 70.8±7.2 years old; BMI 28.7±3.5 kg-m 2) participated in an observational and cross-sectional study.
Participants were requested to walk at comfortable (CG) and maximum gait (MG).
Both modalities were performed on a 70-meter elliptical circuit over three minutes.
Distance and working heart rate were recorded for the corresponding calculation of average gait speed (AGS), physiological cost index (PCI) and used working heart rate percentage (% uWHR).
With this information the FR% was determined by the percentage ratio with AGS, PCI and %uWHR under comfortable versus maximum dem...
