1) Why does a cardiovascular athlete, such as former Tour de France Champion Chris Froome, have to be aware of the concept of cardiovascular drift? Explain in great detail to this athlete what cardiovascular drift is and also identify the factors that will affect his cardiovascular drift during a long cycling training ride

2) Thermoville Heat, a new environmental exercise physiology center, has just contacted you for a consultation. They mentioned that many individuals (i.e. fans) who attended the very windy and cold Virginia High School State Football Championships complained of being extremely cold last year. The Thermoville Heat people believe that these football fans must have been losing heat. Thus, explain all four ways that the human body can/loe heat and choose three of the ways of losing heat and explain how they apply to the fans at the cold and windy football. Remember to be very thorough in your explanations

3) Tommy and Jimmy Thimble are fraternal twins. Tommy is a shot putter (i.e., a power athlete) while Jimmy is a marathoner. They hear you are a muscle guru and would like to know how their muscles (i.e. muscle fiber types) and energy systems adapted differently to their specific training. Explain, in detail, all possible factors associated with their question. Also, justify to whom the anaerobic glycolysis system is most important
OR
4) Tommy and Jimmys dad, Perry, doesnt believe you are a muscle guru and asked if you could explain the process of a muscle contraction from efferent neuron stimulation/activation to relaxation. You must identify all microstructures that comprise a muscle as a whole and are associated with the excitation/contraction coupling phase as well as describing their importance. Do not forget to indicate what the powerstroke and the sliding filament theory are, plus note their significance

5) Perry (Tommy and Jimmys father) told his brother Tyson, who is a physicist, about you. Tyson would like to know how contractile speed relates to neurons and muscle fiber type as well as what the relationship is with muscle fiber types, exercise intensity, and duration. Also, Tyson wants you to tell him what actually determines the muscle fiber type and how the body determines which fiber type will be recruited. Finally, Tyson asks what the relationship is between motor unit size, numbers recruited, and force production. Answer all of Tysons thought provoking questions .
