The physiological aspects of goalkeepers training prescription introduction

  1. 1. The physiological aspects of goalkeepers training prescription How many of us have heard that football is a sport of details? I believe we all have, right?! Even more, when it comes to the goalkeepers, where errors and possible failures are pointed by numbers "specialists". Yes, it’s a special position, and details really make great and repercussive difference. But there are thousands more details, not seen, behind that one centimeter between a goal conceded in the last minute and the "miraculous" save that will give the title to his team. "Happy is he who transfers what he knows and learns what he teaches”, Cora Coralina. It may look cliché, but I could not find another better way to describe my satisfaction and my intention in writing for the "voagoleiro.com". Today I will start a series of articles about the physiological, biomechanical and cognitive aspects of the goalkeeper position. This series aims to provide "tools" to the goalkeeper coaches, so that, when planning our training, we can have the ability to raise the performance of our athletes to the highest possible level. As I said at the beginning, there are thousands of details; and I will try to write as simply and practically as possible. Before starting a training plan, we must understand how the body of the human being works, or better, how the body of an athlete works. The beginning of everything is the energy sources, responsible for every movement of the athlete's body. And the first and most important source of energy for a goalkeeper is known as the phosphagen system. And that will be the theme of our first articles in the series. To improve athletic performance, there are several training principles that must be followed to get the most out of each training session. Failure to do so is the same as delaying the development of specific skills and / or performance. In addition, to better plan the correct intensity, frequency, and duration of the training program, there are other factors that must be
  2. 2. considered according to your reality, such as age and gender, technical and motor level, physical condition, experience, genetics, nutrition, environment, calendar, etc. Any and all physical activity provides great demand for energy transfer. In short duration actions, such as an attempt to cut off a corner kick, or a simple dive motion, the energy demand exceeds by 120 times the values when at rest. Intensive activities of short duration require immediate energy; this energy comes almost exclusively from within the muscle itself, called the phosphagen system, producing chemical energy in the form of adenosine triphosphate (ATP) and phosphocreatine (PCr). The amount of these energy compounds can be completely exhausted in 5 to 8 seconds or up to 30 seconds when under extreme stress. If we imagine a specific goalkeeper action in games, very rarely, or never, we will see this action taking more than 30 seconds, be it a 1 on 1 situation, or even an incredible sequence of saves. Therefore, we should pay special attention to this energy system when planning our training.
  3. 3. "The art of prescribing exercise involves the successful integration of exercise science with behavioral techniques in a manner that results in long-term program compliance and attainment of the individual’s goals." In the next articles I will give emphasis on how to train the phosphagen energy system. References 1. Boone, T. (2013). Introduction to exercise physiology. Jones & Bartlett Publishers. 2. Ehrman, J.
