Surface Electromyography Amplitude During Sustained Isometric Contractions Connor Howe 31451131 HMKN 310 UBC Okanagan Greg duManoir October 18, 2015 Introduction Muscle fatigue is the result of a series of structural, metabolic and energetic changes in muscle fibers caused by changes in nervous system efficiency as well as decreased oxygen and nutrient supply (Cifrek, Medved, Tonković, & Ostojić, 2009). A major driving force behind muscle fatigue is lactate buildup. As lactate builds…

he 2008 PA Guidelines state, an adult should get at least 150 minutes of moderate intensity PA(3.0-5.99METs) a week or 75 minutes of vigorous intensity PA(6.0 METs or more) a week. Surprisingly, even with a whole day of doing close to nothing I have surpassed the PA Guidelines for both moderate and vigorous intensity. This is not one of my typical weeks, which surprised me when I learned I have met the PA Guidelines. Mainly because I am a track athlete and I am used to my weeks being filled with…

Maximal Oxygen Consumption; also known as VO2max, is defined as the highest rate at which oxygen can be taken in and used by the body every minute during intense exercise (2). It is measured in mL/kg/min, defined as the milliliters of oxygen per kilogram of body mass per minute. VO2max is generally measured by using a maximal exercise test to physical voluntary exhaustion where speed or power are increased consistently, requiring more oxygen uptake each phase. (1) Exercise intensities are…

Coaches Toolbox Coaches are very influential in their players lives. Their influence can be for the good of the player or can be detrimental to their performance. Some of the greatest coaches in history used a variety of sport psychology concepts and techniques to help their athletes reach peak performance. Since I am seeking a career in the field of coaching, it is essential that I gain the knowledge and know how to implement some of these techniques to help better my clients. This project…

I don’t know why? But when people start growing up or start getting older they start slowing down in their triathlon performances. Not long ago, I saw an old man in great shape doing a triathlon and something caught my eye because he had been a word champion in the ironman competition; but although he was very slow in the competition that I saw him in. later that same day I got home and started researching his name online and I found some of the races that he had done with the times and he was…

A measurement that measures the maximum volume that can be obtained by an individual is called VO2 max. VO2 physiology is two different categories 1) Utilization and 2) Delivery. Utilization is being able to extract and use oxygen. Delivery is about the transportation of oxygen cells either through the CVD or pulmonary system. VO2 is important for exercise and transporting oxygen to the muscles. VO2 max is important to health because it gives information on the function cardiac output of the…

Allen Hendricks, an educator and Program Coordinator from National Strength and Conditioning Association (NSCA), performs a podcast with Dr. Ben Router discussing injuries in endurance athletes. Professor Ben Router is also strength and conditioning coach and a Associate Professor at Cal University in Pennsylvania. According to Dr. Router, endurance training has increased over the years, stating that more Americans are becoming more physically active. Also, organizations are creating fund…

When the body is at rest, the heart beats at a normal pace. As kinetic energy is applied to the body, it is put into work which can make the heart rate increase a bit. Speed requires kinetic energy in order for it to be done. Depending on how fast the speed being applied to the body, the harder the body will work affecting the cardiovascular and respiratory systems. Elements like force, friction and mass also play a huge role in this experiment. The scientific definition of speed is how fast an…

Don’t get the winter blues. There are lots of ways that you can stay active and healthy during the winter. You can use the stairs to workout, hit the ice for some skating, take a fitness class and #1 Use The Stairs Stairs can be a great exercise element.

You can find stairs in lots of different places that are inside and safe to use for winter workouts. You can walk the stairs in your…

Chapter 14 studies careers in therapeutic exercise. Therapeutic exercise is defined as the “systematic and scientific application of exercise and movement experiences to develop or restore muscular strength, endurance, flexibility, neuromuscular coordination, cardiovascular efficiency, and other health and performance factors” (Lecture). The goals of therapeutic exercise professionals are to help people acquire skills and to restore lost functions that are considered normal or expected for…
