Anyone who had an opportunity to mingle with college or professional football players might have experienced a sensation similar to standing in a forest. Football players are big people in terms of height, body mass, or both. Sustaining the physiology of their bodies requires a daily nutritional intake that would satisfy the average construction worker for days. But coaches who understand how football affects the human system take the business of physiology seriously.

Players' Duration

Football performances consist of elements that include team strategy, executing and reacting to strategy, individual skills and physical match-ups. Players have a relatively short period when their bodies can perform at peak levels. With the exception of a few who possess remarkable desire and a body that supports their desire, most players have a limited performance window. The average career of an NFL running back is four years because of the abuse they endure. Conversely, linemen don't collide on every play, but typically engage their opponent. As a result, linemen have a larger performance window that might equal that of a quarterback who endures limited collisions. Certain injuries can force a player to retire early.

Fatigue

Demands on the physiology of players is a factor in terms of the rest that's necessary during games. Over the course of a 60-minute game, players have a number of rests between plays and between possessions. However, during activities on the field, they exert peak levels of energy by running, blocking and tackling. Football players endeavor to avert premature fatigue through weight and resistance training, along with a nutritional program. It is the coach's responsibility to ascertain what physiological level each of his players must maintain to avoid fatigue.

Nutrition

The number of calories a player requires depends on the position he plays and the level of training at any given time. Typically, extensive training and conditioning takes place prior to the season and is reduced to maintaining performance levels during the season. Football players need to consume calories in amounts that support their particular physiology. Some might require 5,000 calories per day and others might require as much as twice that amount. A sports dietitian or qualified nutritionist should be brought in to evaluate the players and create individual nutrition plans that support each player's physiology.

Damaging The Body

Colliding with another football player at full speed has the potential for physical damage and injury. However, players who are in condition to survive these collisions over the course of a season must guard against damaging their physiology with poor eating habits. Fried food, sweets and alcohol are known to affect the physiology of certain bodily functions and organs. The effects of improper nutrition might not show at first, but can emerge during a game, leaving a player vulnerable to serious injury. If you play football, it's important to resist any inclination to smoke, drink alcoholic beverages or eat the wrong types of food.
