Class Summary - Today we continued our lectures on lifelong fitness. We discussed different activities that can be used to improve each component of fitness (Cardiovascular endurance = running, flexibility = stretching, body composition = swimming, muscular strength = heavy lifting, muscular endurance = light lifting etc.). We compared 5 pounds of fat and 5 pounds of muscle and saw that fat takes up way more space. We discussed that to lose a pound of fat we need to burn 3,500 calories so it is not healthy to lose or gain more than 1-2 pounds per week because it is hard on the heart and would not result in long term weight loss. Today we discussed the difference between aerobic (needs oxygen, longer lasting) and anaerobic (no oxygen, short bursts) exercises. We also discussed isotonic, isometric and isokinetic exercises. We addressed dietary supplements. We talked about the need to do research about supplements because some of them are not regulated by the FDA. It is always best to get our nutrients from food. We finished off talking about the FITT principle. The FITT principle is an acronym used to help us put together a fitness plan. F = Frequency (how often), I = Intensity (how hard), T = Time (how long), T = Type (what kind).
