    Body composition measurements to determine goal weights should be assessed twice annually,115 with no less than 2 to 3 months between measurements50 for most people.

    Active clients and athletes in weight classification sports should not gain or lose excessive amounts of body weight at any point in their training cycles. Athletes and clients should attempt to maintain levels that are close to their weight and body composition goal when not competing and maintain their goal weight and body composition during competition. Excessive fluctuations in body weight or body composition (or both) can negatively affect the body, including but not limited to changes in metabolic activity, fluctuations in blood glucose levels, and muscle wasting.14 Athletes in weight classification sports should have individual monitoring plans, such as assessments at least once per month in the off-season and at regular intervals, not to exceed once per week, to monitor for weight fluctuations.115*
