INTRODUCTION

The physiological demands of football game are represented by the intensities of which are carried out various activities during a match. This has implications in terms of physical capability of the players and also suitable for the determination of training regimes. Because the training and competence schemes of professional players understand their occupational roles, this has implications for their daily activities, daily energy requirements and caloric expenditures. There are also implications for the prevention of injury to the extent possible, and for the proper restoration of soft tissue injuries (Nunome et.al, 2013).

The intensity of effort during competitive soccer may be indicated by the total distance covered. This represents an overall measure of the rate of effort, which can be divided into discrete actions of a particular player throughout the game. The actions or activities can be classified according to type, intensity (or quality), duration (or distance), and frequency. Activity may be established based on time, so that can be averaged exercise-pause proportions. Then, these ratios can be used in physiological studies designed to represent the demands of football, and also in the conditional elements of the training programs of the players. These work rates can be increased through monitoring of physiological responses, when possible.

In this article, we cover different aspects of the physiology of football. Before reviewing the game physiological responses considered effort rates during the match, and the actors that influence the intensity profiles. The answers are restricted to the heart rate and metabolic measurements. Implications are also mentioned in the compatibility between the demands of the game, the training stimulus, and measures of physical capacity, although the review of physical fitness of the players is out of the optics of this article.

PHYSIOLOGY OF ACTIVITIES RELATED TO THE GAME

The distance covered in a match underestimates the energy expended, as no take into account the additional demands of the game skills these include the frequent accelerations and decelerations, careers angular changes of direction, jumping to compete for possession, trademarks, avoidance brands, and the many aspects of direct involvement in the game. There have been some attempts to quantify these additional physiological demands.

Dribblear with the ball is an example of an interesting skill game for physiological research in the laboratory field.  The physiological responses to dribble a soccer ball, on a treadmill at speeds of 9, 10, 5. 2 and 13.5 km / h, every effort for 5 minutes. A box of bounce in front of the tape returned the ball to the player's feet after each touch forward. The procedure allowed precise control of player activity, while measuring the exhaled air, blood lactate level, and perceived exertion. was observed that the energy cost of dribbling, which involved a touch of the ball every 2-3 complete cycles of strides, increased linearly with running speed. The additional cost remained constant dribblear 5.2 kJ / min. It is likely that this value varies in field conditions, according to the proximity of the ball control exercised by the player.

When performing a "dribbling" having a good control of the ball, the stride rate increases and shortens the ...
