Could a Short Incremental Test Be a Valid Cardiorespiratory Efficiency Assessment Tool in Obese Adults? A Comparison between Two Exercise Testing Protocols.

ABSTRACT:

Background

To assess cardiorespiratory efficiency in obese adults, two exercise test treadmill protocols with 2- or 3-minute stages were compared.

Methods

Thirty-six obese adult subjects were involved in this study. Sixteen men (age 51.5±10.5 years; body mass index [BMI] 36.7±4.8 kg/m²) and 20 women (age 42.4±12.4 years; BMI 36.5±4.7 kg/m²) performed submaximal incremental graded tests on treadmills with 2- or 3-minute stages on different days. During each testing session, heart rate (HR), oxygen uptake (VO₂ mL/min/kg), rate of perceived exertion (RPE), fat oxidation (FO) at maximal fat oxidation (MFO), and maximal fat oxidation zone (Fatmax zone) were measured.

Results

No differences were found for HR, VO₂, and RPE at MFO b
