Football Body

Football is one of the most physically demanding sports that can be played. (Drust, B., Atkinson, G. & Reilly, T., 2007.) stated that football is a mixture of high and low exercises in a game which is accompanied by other varied movements and executing specific skills. In difficult sports like these, the body's functions demand more effort and more energy due to the nature of football. In football, there are different factors that can affect the physiological demands of the body during football games like the environmental factors, the importance of the game, the ball possession of the team, player's physical capacity, technical qualities, playing position as well as the player's tactical role in the game and age. In general, in a game, there

For example, midfielders have the highest maximal oxygen intake and have low muscle strength. There are also marked differences with players of the same position which may be due to playing style and tactical role in the game. Playing formations in football on high-intensity running and technical performance also has effects on the physiologic demand (Tierney P.J., Young A., Clarke N.D., Duncan M.J., 2016). In the advancement of technology, game-related sports performance could now be measured and observed. One of the monitor systems that can assess physiologic and motion analytic data is the Zephyr Bioharness GPS satellite technology. The device measures five physiological and activity eight variables (heart rate, breathing frequency, skin temperature, accelerometry, and posture) in real time. The importance of this device to sports is that helps in measuring the effectiveness of a training program, quantifies subjective measurements such as gaining insights on workload and intensity and lastly optimizes the rehabilitation process of recovering athletes. Not to mention other countries around the world are able to utilize these physiological data with the use of these monitoring systems effectively and efficiently in training their players and

The secondary aim would be to compare the physiological demands per position (Goalkeeper, Forwards, Midfielders, and Defenders) in order to know the physiological demands that need to be evaluated in each position most specifically the goalkeeper since it is the position that is given the least importance in most research studies conducted about the sport. For both of these objectives, the tools that will be used is the Zephyr Bioharness monitoring system and time-motion
