Key result
Body weight support of 30% significantly reduced oxygen uptake and heart rate compared to unweighted walking at 50% VO2max, but not at 35% VO2max.
Why the study?
The impact of body weight supported treadmill training on oxygen uptake and cardiovascular response is variable, possibly due to the level of body weight support or exercise intensity.
Does 30% body weight support during treadmill walking reduce oxygen uptake and cardiovascular response compared to 0% support in healthy adults?
Does 30% body weight support during treadmill walking reduce oxygen uptake and cardiovascular response compared to 0% support in healthy adults?
Absolute Event Rate: 15.5% vs 19.3%
p-value: p=<0.05
Body weight support of 30% during treadmill walking at higher intensities (50% VO2max) significantly reduces metabolic and cardiovascular demands in healthy adults, suggesting a safe way to exercise complex patients at higher intensities.
Body Weight Supported Treadmill Training (BWSTT) is effectively used in locomotive training for patients with neurologic and musculoskeletal deficits. The impact of BWSTT on oxygen uptake (VO2) and cardiovascular (HR and BP) response in patients has been shown to be variable, possibly due to level of Body Weight Support (BWS) or exercise intensity.

Van et al. (2022) studied Healthy adults (n=11). 30% Body Weight Supported Treadmill Walking vs. 0% Body Weight Support was evaluated on Oxygen uptake (VO2) at 50% VO2max (mL/kg/min) (p=<0.05). Body weight support of 30% significantly reduced oxygen uptake and heart rate compared to unweighted walking at 50% VO2max, but not at 35% VO2max.
