Introduction
I am a football/futsal coach educator and a full-time academic professor with a specificity in neuromuscular and cardiovascular physiology. My current research interests focus on the effects of training load monitoring, exercise recovery intervention on autonomic nervous function, effects of biofeedback training on cardiovascular adaptation, and effects of ageing on neuromuscular function, physical activity and health, and football/futsal sciences.

Band 3 protein is a Cl-/HCO3- transporter on the red blood cell (RBC) surface with an important role in CO2 excretion. Greater band 3 expression by roughly 20% is found in people with the GP.Mur blood type. Intriguingly, a disproportional percentage of those with GP.Mur excel in field-and-track sports.
