Re: “Frontline on football

AWARNESS. Learning or understanding is of no vaule unless we take the correct action. The irony of football being a team sport is we need a team effort in taking care of these young men that play a game. Coaches, trainers, parents and medical providers must learn from young men dying. When investigating Heat Related Deaths in football, players are dying where water was plentiful, there were rest breaks, coaches and athletic trainers were present, the players showed no visual signs of stress, and some died days later in hospital. All had passed physicals. WE MUST REEVALUATE WHAT IS STILL NOT BEING DONE. The number one cause of Exertional Heat Stroke is high intensity exercise combined with a low MET score (Metabolic Equivalent of task) not DEHYDRATION. All physical exertion produces heat. The amount of heat produced is directly proportional to the rate of energy expended, measure in a MET score. MET scores also measure VO2(Volume of oxygen delivered & consumed) . Football players with low Peak VO2 measurements have the potential for more HEAT STORAGE during exercise. Players with low MET per min scores produce metabolic heat from muscles and lack the circulatory (cardiac output) to ensure a high enough skin blood flow for heat to be release to environment for proper thermal balance. As the MET score of a player improves from proper AEROBIC STRENGTH training, the ability to withstand heat stress improves independent of acclimatization and heat adaption. The MET score is an exact measurement and direct link to the bodies ability to release heat from core to shell. A coach determines the intensity, duration and frequency of practice in a week without INDENTIFYING which players have the lowest or highest heat tolerance. While there are many factors that contribute to Exertional Heat Stroke a young overweight player with a MET score of 20ml/kg/min/vs a player at 60ml/kg/min will the longer practice last store more heat even when not dehydrated. The beauty of indentify players before August that have these deficiencies is exercise prescription can be given off data of test results that gives the player time with proper training for physiological change ( increase in MET per min). Coaches have change their views towards water being available at practice since 1970. That however did not come from them understanding Thermal Balance, but LEADERS working together to influence their ACTIONS. What some are calling a tragedy is negligence not to act on what we can prove. Mike Craven, TRUE FITNESS SOLUTIONS.
