chapter Learning Objectives • Learn how our bodies change the food we eat into ATP to provide our muscles with the energy they need to move • Examine the three metabolic systems that generate ATP 2 Fuel for Exercise : Bioenergetics and Muscle Metabolism Terminology • Substrates – Fuel sources from which we make energy (adenosine triphosphate [ATP]) – Carbohydrate‚ fat‚ protein Measuring Energy Release • Can be calculated from heat produced • 1 calorie (cal) = heat energy required

Fractures A fracture is a break‚ usually in a bone. Fractures commonly happen because of car accidents‚ falls or sports injuries (Fractures: MedlinePlus). Stress fractures‚ which are very tiny cracks in the bone‚ can occur when there is an overuse of the bone which is common with athletes(Fractures: MedlinePlus). You may also be prone to broken bones if you have osteoporosis or another bone disease which causes weakening of the bones (Fractures: MedlinePlus).When I fractured my wrist I experienced

Comparison of Muscle Proteins to Infer Evolutionary Relationships of Mammals‚ Fish and Birds Abstract This experiment used electrophoresis to examine the makeup of muscle proteins from two mammals (cow‚ Bos taurus; bear‚ Ursus americanus)‚ two aves (chicken‚ Gallus gallus; turkey‚ Meleagris gallopavo)‚ and two fish (King Salmon‚ Oncorhynchus tshawytscha; Albacore Tuna‚ Scombridae unclassified). The hypothesis was that as species have diverged evolutionarily‚ the makeup of their muscle proteins

Muscle contractions are the way that humans are able to move within the enviornment that surrounds them. To be able to understand the complexity of movement‚ there needs to be an understanding of the gross and micro-anatomy muscle contraction‚ and an understanding of the physiology of muscle contraction. This paper will provide an explaination of both the anatomy and physiology of muscle contraction. Anatomy of Muscle Contraction There are three types of muslces within the human body: skeletal

exercise. Although stretching doesn’t reduce bodily fat nor does it gain muscle; it does set a good foundation for you to perform the necessary activities that lead to good health. With proper flexibility‚ many functions that were previously not achievable can now be done. For instance‚ a tennis game can be fun for a little while. But as your muscle tense up‚ you risk probable sourness and cramping. With good flexibility‚ your muscles stay loose and relaxed and your attitude toward the tennis game and
