We all know that great football players are big and fast, but those of us who have no direct experience playing or coaching football typically know little about what other characteristics are important to success in football. Likewise, most of us are unaware of how coaches condition their players, what the most common injuries to players are, and how diets for football players differ from diets of other athletes. The following is designed to address these issues and respond to questions that I thought may be of interest to athletes and coaches alike.
Other critical factors include reaction time (an important component of agility), vertical jumping ability (as a marker for power of the lower body), and upper body strength. All things being equal, in a contact sport like football, a larger player generally has an advantage over a smaller one, but in the real world, especially at the high school level, bigger is not necessarily better. The high school lineman often has to play both sides of the ball, and a player with better quickness and skill can often overcome a larger opponent. Speed in general, and specifically the ability to accelerate quickly, is without question the single most important physical factor, regardless of position. Speed can make up for deficits in either strength or skill. Upper-body strength and reaction time are two other characteristics that are necessary to be a successful football player, especially at the positions of interior lineman, running back, and defensive back. Bigger isn't necessarily better if the athlete excels in the other characteristics.
The core is defined as the lumbar-pelvic-hip complex and consists of the gluteals, abdominals, hip flexors, and spinal muscles. The core is where our center of gravity is located and where all power movements begin. Squats, dead lifts, leg presses, abdominal curls against resistance, and leg raises are excellent exercises for developing the core musculature. Of course, upper body strengthening with bench presses, military presses, and various exercises to strengthen elbow flexors and extensors are also important for football players. The combination of developing a good strength base in the weight room and developing the technical ability to execute a skilled movement at a high speed during field drills is the key to successfully enhancing performance of a power movement. Without speed, strength will not allow the athlete to generate adequate power. Properly performed strength and power movements can have a dramatic effect on an athlete's performance. Weight room exercises should be used to prepare a foundation of strength, whereas football-specific drills should be used to "fine tune" the strength of the muscles used in football. Time spent in the weight room building core strength is essential for the successful football athlete. Other more sport-specific drills are also important but are probably not as efficient for building sheer strength and power.
Next, have the players perform a series of sprints, stride stretches, and plyometric rebound jumps on one and two legs. These drills do a fantastic job of preparing the athlete's body, particularly the joints, for the rigors of practice and competition. During the first five days of practice before heavy contact work, have players also perform agility circuits. Set up 10 stations with various drills: plyometrics with resistance, grass drills, running against elastic ropes for resistance, jumping ropes, and one-legged running. At each station, have players work for one minute at high intensity before moving on to the next station. Try to design these drills to be as specific as possible to football. During the main part of the season, select from a menu of high-intensity intervals (repeat 40-yard sprints), long slow distance runs, and a variety of football-specific agility drills.
Educate the players about the importance of avoiding dehydration and its detrimental effects on performance and health. Cajole, beg, and insist that they drink enough fluids during hot and/or humid conditions.
Athletes prone to muscle cramps may need to take in more sodium and potassium in salted sports drinks and in their daily diets. Encourage players to consume a sports drink before, during, and after practice. Guidelines are: 16-20 oz (450-600 ml) 1-2 hours before exercise, 7-10 oz (200-300 ml) every 15-20 minutes during exercise, and at least 24 oz (720 ml) after exercise for each pound lost. Players should be weighed before and after practice to assess average fluid losses. They should be reminded to drink before they are thirsty and to drink on a schedule.
Players should carry a squeeze bottle with them during the day so that they can drink between workouts, classes, and practice. They should know the warning signs of dehydration: dizziness or lightheadedness, cramping, nausea, fatigue, and dark-colored urine. Some players are cramp-prone. These players tend to sweat early and very heavily. They typically have a history of cramping and produce sweat that tastes salty. Some are following a low-salt diet due to a family history of high blood pressure. They also tend to be the most fit and athletic players at their positions. For these players, we add 1/4-1/2 teaspoon of salt to 16 oz of a sports drink and encourage them to eat more salt in their daily diets.
The likelihood of injury can be reduced by making certain the athlete engages in a well-organized and supervised year round training and conditioning program at an appropriate level of intensity and occasionally under extreme environmental conditions. Strength training and skill training are the best approaches to preventing these injuries. Strength training protects the joints from trauma, and skill training can help prevent injury by improving the athlete's proprioception, i.e., his ability to judge the position of his body and its parts in space.
Overall energy (calorie) needs and specific nutrient requirements vary depending on time of season, body weight, maturity, personal food preferences, and position played. For example, an offensive lineman is focused on strength and power, whereas a running back is more concerned with quickness and agility. I develop meal plans accordingly to meet the individual nutrition and performance goals of the athlete. The timing of calorie intake is important. The ideal eating pattern for athletes is grazing, i.e., eating small meals throughout the day, to maximize energy intake for training and recovery.
Quick recovery is especially important for football players because they often work out more than once per day. Calorie needs should be met with high-energy, nutrient-dense foods. Consuming enough carbohydrate (8-9 g/kg or 4 g/lb of body weight) from foods such as fruit, cereals, breads, rice, pasta, vegetables, and some dairy foods each day will minimize fatigue and maximize training. Protein needs (1.6-1.7 g/kg or 0.8 g/lb body weight) can be met with lean protein sources, including meat, poultry, fish, dairy foods, eggs, legumes, and nuts. Getting enough protein on a daily basis can be a challenge for college players due to budget constraints.
Calculate Your Protein Needs:
Large players need to take in more total calories than do most other athletes. Sometimes the sheer volume of food necessary to achieve this can be overwhelming for the athlete. This is where nutritional supplements such as carbohydrate energy drinks and meal replacement beverages can be useful.
College athletic departments are particularly concerned about supplement use among athletes because of the potential for these supplements to be contaminated with banned substances. Any student who tests positive for a banned substance such as anabolic steroids or ephedrine is ineligible for participation in regular season and postseason competition for one year. Institutions may not provide substances such as amino acids, chondroitin, creatine, glucosamine, l-carnitine, and protein powders to athletes, but the athletes may use these supplements on a personal basis. Players need to know and want to know what dietary supplements they can use and how to use them appropriately. An important role of the sports nutritionist is to help athletes make informed decisions. I believe that a team approach is essential for determining supplement policy and procedure because each team member, administrator, nutritionist, physician, trainer, coach, and strength coach looks at the issue a little bit differently. Supplements are evaluated in terms of their safety, effectiveness, potency, dosage, and risk-benefit ratio.
