Calorie needs vary from athlete to athlete. Below is a quick calculation to estimate
your calorie goals. Use your current weight in pounds and multiply by the activity
factor listed below. For example: a 150 lb woman practicing softball 4 days per week will use 150 x 16 = 2400 calories/day
Use this formula: weight in pounds X activity factor = approximate daily calorie need
MEN
Moderate-intensity workouts 3-5 days/week or low intensity and short-duration training
daily use activity factor 17
Training several hours daily use activity factor 18.5
Rigorous training on a near daily basis use activity factor 20.5
Extremely rigorous training on a near daily basis use activity factor 23
WOMEN
Moderate-intensity workouts 3-5 days/week or low intensity and short-duration training

Training several hours daily use activity factor 16.5
Rigorous training on a near daily basis use activity factor 17-18
