The magnitude of the moment of a force acting about a point or axis is directly proportinoal to the distance of the force from the point or axis. It is defined as the product of the force (F) and the moment arm (d).
The student athlete child between the ages of 9 and 13 should consume between 2,000 and 2,600 calories, and if they are between 14 and 18 they should consume between 2,800 and 3,200 calories. It is also important that the types of calories the athlete consumes are balanced between carbohydrates, proteins, and fats.
âWhat they eat, when they eat and how much they eat will affect how they perform, how they feel and their outcome,â said sports nutritionist Heidi Skolnik, who has worked with the New York Giants. The key to fueling football players is figuring out how many calories they need to get through the day. âThe number of calories you need is determined by your size, the intensity of your workout and the duration of your workout,â Skolnik said. During summer training camp, a 300-pound linebacker could easily consume a combination of proteins, carbs and fats â adding up to 7,000 calories a day. While that may seem like a lot, Skolnik said that athletes who under-eat could face serious consequences.
