Effect of Exercise on Muscle Fatigue Question: Does exercise such as jumping jacks effect muscle fatigue? Hypothesis: This experiment tests the effect of exercise (jumping jacks) on muscle fatigue of the body. Exercise will make a person squeeze a clothespin fewer times in one minute compared to the person not exercising because exercising takes away a muscle’s energy. Therefore a resting person will have more energy for the clothespin squeezing. Methods and Materials: Materials for this experiment

Differences in Cardiovascular Fitness that Effect Nonsmokers and Smokers Kayla Forbes 2-15-12 Bio Lab 140/77 Hilde Stawski Abstract: The goal of this experiment was to find out how smoking affected nonsmokers‚ light smokers‚ and heavy smokers heart rate during cardiovascular endurance. The participants will record their pulse rate before and after every minute for six minutes after the step test. As predicted‚ the heavy smokers had an increase in pulse rate that was twice as high as the

A Comparative Study of Long-term and Short-term Memory between Athletes and Non-Athletes ABSTRACT Physical exercise has demonstrated to considerably affect stimuli in the brain to increase an individual’s memory. Athletes will have better long-term and short-term memory compared to those who are not athletes. The intent of this study was to evaluate and compare the long-term and short-term memory of athlete and non-athlete. Twenty participants were tested‚

Chapter 4 Exchange Background e-Learning Objectives Exchange surfaces All of the cells in your body need constant supplies of oxygen and nutrients‚ and need to get rid of waste materials‚ such as carbon dioxide‚ that are produced in their metabolic reactions. These substances are obtained from‚ or released to‚ the external environment‚ through your body’s surface. Cells and organisms have problems of scale to solve as they get bigger. As an organism gets Cube with 1 cm sides bigger‚ both its

Respiration is the process that takes place in every living cell to make energy available to the body. Energy is vital for us to carry out many life processes such as movement and so respiration in essential to life. During respiration glucose and oxygen are used in a reaction that produces energy and gives out carbon dioxide and water as waste products. Glucose is obtained by digestion of food and oxygen is taken from the air during a process called breathing or ventilation. Pulmonary Ventilation

The event that I have decided to undertake from the Athletics unit this term and elaborate more on is knowledge and understanding of the 400-meter sprint. This event is usually taken place on a full size athletics field‚ which consists of one whole lap in a fast sprint‚ which takes around a time of a minute. In that minute the runner would experience all factors of the race‚ from intensity to recovery. In the 400 meters‚ intensity relates to the chosen speed‚ which is usually expressed as a percentage

Planning Introduction Stomata are pores on the bottom of leaves of vascular plants. The function of stomata is to allow gaseous exchange (transpiration) between the plant and the external environment (see diagrams below). This process is carried out by the plant‚ which controls the opening and closing of stomata via the guard cells. The more stomata a leaf contains the greater the rate of gas exchange and the less water it will be able to accumulate. Stomatal pores are formed between

Study Guide for the Final Exam Here are the rules: please do not call me or email me questions about the study guide. I will answer questions about the study guide during the brief review before the exam itself. You cannot memorize the answers to the questions and do well on the exam- the questions are meant to stimulate thinking‚ not to be answers. Please remember to review the chapters on shock and MODS as there are questions on this content. 1. There are several ABG questions; remember
