stages) compared to sham (134.98%MCAv stages) while HR AUC revealed a greater heart rate occurred during the LBNP condition (153.76%HR stages).Exploratory analysis on individual symptoms revealed 'pressure in the head' was reduced at the 60 min post-exertion time for LBNP condition (p= 0.032).Conclusion LBNP reduced MCAv while augmenting HR during exercise, resulting in fewer symptoms one-hour afterward.This approach shows promise for a novel recovery method for improving outcomes from concussion, especially for PPCS.
