D.R. Swanson, "Atrial Fibrillation in Athletes: Implicity Literature-Based Connection Suggests that Overtraining and Subsequent Inflammation May Be a Contributing Mechanism." Medical Hypotheses 66, no. 6 (2006) 1085-92.Information changes constantly especially in the fitness field. What was valid 10 years ago is rarely used today however we need specifics because talking in generalities will get us no where.
also...unless you have actual experience training people for a minimum of at least 5 years there is very little that you can open my eyes to that i already haven't read, tested or tried myself.
but lets see you dig up these studies, professor.
