In contrast, we focus on shivering and alternative NST mechanisms in skeletal muscle, which may contribute to obesity resistance.\u00a0We compare the dynamics of cold adaptation of obesity-prone C57BL\/6J (B6) mice, which rely on BAT, with obesity-resistant A\/J mice, which preferentially recruit muscle NST, assessing their EE and core body temperature by continuous indirect calorimetry and characterizing muscle metabolic changes by integrated multi-omics approaches.\u00a0We found that compared to the B6 strain, A\/J mice exhibit decreased shivering endurance but can gradually recruit muscle NST capacity. However, this muscle NST impairs the efficiency of physical activity, increasing the energy cost of exercise and thus potentially protecting animals from developing obesity.<\/p>\n<p><strong>Contact at IPHYS: <\/strong>Petr Zouhar (petr.zouhar@fgu.cas.cz)<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Annotation:\u00a0Thermogenesis can account for a substantial fraction of energy expenditure (EE) and thus affect the development of obesity.
