Kinesiology 110 Spring 2009 Barry Braun PhD Lecture 10 guestions 1 Are energy bars necessary before exercise because you need more energy If not why not 2 What might you need before exercise Why 3

greater your risk to get heart disease Of not why not What are some things that are not being considered 5 Even if all of the other factors are accounted for can you say with certainty that more fat in the diet more heart disease Why not 6 What are some of the barriers to doing an EXPERIMENTAL study in which you take a group of people and control the amount of fat in their diet and assess which ones get heart disease 7 Why is it unwise to change your diet or exercise patterns based on the results from just one study Dr Barry Braun Kinesiology 110 Spring 2009 M0 A A 9 0R9 2 9quot 1 E e QM Mus
