Exercise Electrocardiogram Lab Purpose The purpose of this lab is to understand the concepts of an electrocardiogram of a normal person as well as understand what a normal ECG and an exercise ECG look like when performing a Bruce protocol treadmill test. Methods Materials- Test subject‚ ECG-12lead‚ 10 electrodes‚ treadmill The subject must have the electrodes properly connected before starting the treadmill test. Remove any hair from the subject before placing the electrodes on. The

heart rate. After running 2.5 kilometres and swimming 250 meters the average person would be quite tired/exhausted‚ but with the correct fitness exercises to work on cardiovascular endurance it would get easier and easier to run such an event. The reason your cardio performance can be improved is because the heart is a muscle‚ and like all other muscles in the body if you keep working it it will adapt to the workload given. This allows us to have direct control of how healthy one of the most important

UNIT 2 As soon as you begin to exercise changes begin to happen within your body. Body systems work together‚ to make sure that you have enough energy to perform. Body systems respond both in the Short and Long-term in response to exercise. It is important to understand the changes that happen to the body as a result of physical activity. You will understand the: Muscoskeletal‚ Cardiovascular and Respiratory responses to exercise through this unit As soon as you begin to exercise changes begin

frequency of the stimulation in cardiac muscle. | amplitude does not change because the cardiacs long refractory period prevents summation. | Why is it only possible to induce an extrasystole during relaxation? | the extrasystole can not occur until relaxation and so we could not achieve wave summation tetanus | Explain why wave summation and tetanus are not possible in cardiac muscle tissue. | Cardiac cells have longer APs and twitches than any other muscle cells‚therefore they do not show temporal

October 2‚ 2012 Skeletal Muscle physiology exercise Electrical Stimulation name each phase of a typical muscle twitch and on the following line. Describe what is happening in each phase. a) latent- is a short period between the time of stimulation and the beginning of contraction b). Contraction – at this stage the muscle reaches its peak in contraction. Relaxation -Muscle is shortened‚ returns to zero and back initial length. In activity 2 how long

Exercise 7 Review Sheet Definitions/Explanations: Respiration: The entire process of gas exchange in the body; it includes each of the following: 1. Pulmonary Ventilation (AKA breathing): The follow of air into and out of the lungs. The result of muscle contraction of the diaphragm. Ventilation consists of two parts: a. Inspiration: The process that occurs when atmospheric gas is drawn into the lungs by way of contraction of the diaphragm which causes expansion of the thoracic

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).
