2022-P: Partial-Body Cryotherapy Acutely Augments Resting Metabolism in Obese Women

Cryotherapy has been shown to reduce pro-inflammatory response, relieve pain and enhance muscles’ post-exercise recovery. Cryostimulation could be also proposed as an alternative strategy to trigger cold-induced thermogenesis in overweight/obese subjects. In this study, 16 obese (BMI: 32±4 kg/m2) women (43.4±4.8 years) underwent Partial-Body Cryotherapy (PBC) (-130°C x 150sec) for 5 days (1/day, h 07:00 AM). Resting energy metabolism (REE) was assessed by indirect calorimetry pre- and post-PBC on day 1 and day 5. Subjects were energy-controlled (physical activity and dietary intake). Before 5th-day PBC, REE was increased by 5.5% versus pre-1st-day PBC values (1755±265 vs. 1664±241 kcal/day; p=0.0005). With a similar design, in a larger sample of 80 subjects (F=61; M=19; 34.4±11.1 years; BMI: 24.4±4.8 kg/m2), REE augmented by 1.89% (p=0.02) after PBC of day 1. In a multivariate analysis, multiple regression output a positive relationship between cryostimulated REE and body weight (Spearman r=0.68; p Disclosure R. Codella: None. M. De Nardi: None. S.
