Wilson Chapter 1 Introduction Supplementation is essential for performance‚ but is energy drinks or sports drinks the best source of nutrients when replenishing glycogen store? The project that I am conducting is concerning the impact of the consumption of chocolate milk and its effects on protein turnover‚ muscle glycogen and performance during recovery from endurance exercise (2).

Lab 6 Biomechanics of Frog Skeletal Muscle I. Purpose This exercise is designed to demonstrate some mechanical and physiological properties of skeletal muscle using the gastrocnemius muscle of a frog. II. Performance Objectives At the end of this exercise the student should be able to: 1. Define minimal (threshold)‚ subminimal‚ maximal‚ and supramaximal stimulus. 2. Explain what is meant by a “graded” response. 3. Draw a diagram of the setup used in this lab exercise. 4. Calculate the

enzyme activity in skeletal muscle‚ particularly the activity of lactate dehydrogenase (LDH). LDH is a glycolytic enzyme which converts pyruvate to lactate in the following equation: LDH Pyruvate+ NADH ------------ Lactate + NAD The reaction above can move in both directions‚ forward (favored by Type II skeletal muscle) and reverse (favored by Type I skeletal muscle and the heart).

2/14/2012 Anatomy and Physiology Muscle Grip Strength Lab Report Introduction: Skeletal muscle is a form of striated muscle tissue existing under the voluntary control of the somatic nervous system (Medscape 1). Skeletal muscle is part of the three big muscle types‚ it is connected to bones by tendons (Medscape 1). Muscle grip strength is significant to an individual because it helps the person know the ability of muscle power and force that they have in their

Thato’s muscle had remained unused for 6 weeks. Once the cast is removed and he steps down from the examination table‚ his muscle begins to contract. Due to this 6 week period of rest‚ the muscles initial strength of contraction may be significantly low as compared to its strength a few minutes later. The strength of contraction of his muscle increases to a plateau‚ which is termed the staircase effect. Due to his muscles low initial strength of contraction‚ Thato loses his balance and falls. 1

Introduction: Skeletal muscle cells are specialized cells that contain multinucleated muscle fibers called myocytes. These myocytes contain thicker fibers that facilitate the release of calcium‚ the generation of an action potential within the sarcolemma‚ and the subsequent production of a muscle contraction. Muscle contractions are a direct byproduct of motor unit recruitment‚ and for this lab we can examine these effects with aid of a finger pulse transducer and a bar stimulus electrode. The

Abstract The purpose of this experiment was to use the muscle tension and the electrical activity in the dominant and non-dominant forearm muscle‚ the flexor digitorum superficialis‚ to analyze the determinants of muscle tension and fatigue‚ and the reasons as to why differences may occur between the dominant and non-dominant arm. The generation of tension in a muscle is determined by the major type of motor unit being recruited‚ as well as the rate in which action potentials are being fired. A subject
