Remotely Supervised Home-Based Resistance Training and Orthostatic Tolerance in Young Physically Inactive Women During COVID-19

Introduction: Orthostatic intolerance (OI) is the inability of cardiovascular system to adequately adjust gravity upon standing, resulting in lightheadedness or syncope. OI can be characteristic pathology (e.g. postural orthostatic tachycardia syndrome), which disproportionately affect women, and compounded by inactivity. Thus, we tested effects remotely supervised home-based, 4-week resistance training (RT) program vs. control on stress response previously inactive young females using NASA Lean Test (NLT). Methods: Systolic (SBP) diastolic (DBP) blood pressures, heart rate (HR) were assessed during NLT, pre- post-training, along with fitness body composition randomized RT (n=7). Results: improved (group*intervention, p=0.047) fat-mass (-3.4±2.9 +0.3±0.7Δlbs, p=0.037) over control. The NLT significantly altered SBP, DBP, HR (all, p<0.01). For interaction group*intervention approached significance (p=0.071), lowering SBP group intervention. In was not significant (p=0.558). HR, (p=0.066). Conclusions: current study, short-term remotely-supervised bands tended decrease young, otherwise healthy, females, suggesting health but perhaps tolerance.
