Reassembling the Field-based Applicability of the Lactate Threshold for Old Age

Abstract This study aimed to investigate the applicability of the Lactate Threshold (LT) to predict maximal oxygen uptake (˙VO 2max ) and demarcate the boundary between the moderate- to heavy- intensity domain (HR m-h ) in old age in comparison to the most utilized methods. A cross-sectional validat...

Description
Summary:Abstract This study aimed to investigate the applicability of the Lactate Threshold (LT) to predict maximal oxygen uptake (˙VO 2max ) and demarcate the boundary between the moderate- to heavy- intensity domain (HR m-h ) in old age in comparison to the most utilized methods. A cross-sectional validation study was conducted. Participants aged 61 to 77 performed a familiarization procedure, an incremental maximal exercise treadmill test (CPX) for ˙VO 2max determination, the Six-minute Walk Test (6MWT), and a discontinuous incremental field test for LT determination.
