CSCS - Study Guide (Chapter 10)

Body Mass Index (BMI)

A measure of excess weight as opposed to excess body fat because it cannot distinguish between excess fat and muscle or bone. (Weight (pounds) / Height (inches)^2) x 703

Voluntary Dehydration

A potentially dangerous weight loss technique that includes the use of diuretics, sauna, water and salt manipulation, and wearing multiple layers of clothing.

Eating Disorders

Any of a range of psychological disorders that can affect both men and women, appear at any point in life, and increase the risk of mortality.

Difference between BMR and RMR

BMR is measured after an overnight fast (12-14 hours without food) with the subject resting supine and motionless but awake.

Anorexia Nervosa

Eating disorder characterized by a distorted body image and an intense fear of gaining weight or becoming fat, leading those with this disease to excessive calorie restriction and severe weight loss. Includes ritualistic behavior including repeated weighing, cutting food into small pieces, and carefully portioning their food.

Bulimia Nervosa

Eating disorder characterized by recurrent consumption of food in amounts significantly greater than would customarily be consumed in a discrete period of time, followed by purging.

Binge-Eating Disorder

Eating disorder characterized by repeated episodes, occurring at least once a week for a period of three weeks, of uncontrolled binge eating.

Isocaloric

Having the same or similar calorific value.

Precompetition Meal

Helps provide fluid to maintain adequate hydration and carbohydrate to maximize blood glucose and stored glycogen levels, while also keeping hunger pangs at bay.

Basal Metabolic Rate (BMR)

Measure of the calories required for maintaining normal body functions such as respiration, blood circulation, and gastrointestinal and renal processing. Accounts for the largest contribution to total energy expenditure, accounting for approximately 65%-70% of daily energy expenditure.

Carbohydrate Loading

Strategy used by endurance athletes to maximize storage of glycogen in the muscles and liver.

The primary macronutrient that is addressed in the precompetition meal is a. fat b. carb c. protein d. vitamin

b

When an eating disorder is suspected, the strngth and conditioning professional should a. monitor the athlete's daily food intake b. require frequent weigh-ins c. encourage further assessment by an eating disorder specialist d. provide nutritional information

c

Which of the following is characteristic of anorexia nervosa? a. normal body weight b. very low dietary fat intake c. preoccupation with food d. secretive eating

c

Pica

The eating of nonnutritive substances for a period of at least one month (i.e. clay, laundry starch, ice, cigarette butts).

Diet-Induced Thermogenesis

The thermic effect of food or the increase in energy expenditure above the RMR that can be measured for several hours following a meal.

To maintain hydration during competition lasting less than 1 hour, it is recommended that athletes consume 3 to 8 ounces of water or a sports drink about every a. 15 min b. 30 min c. 60 min d. 2 hours

a

Which of the following makes the GREATEST contribution to total energy expenditure? a. resting metabolic rate b. physical activity energy expenditure c. thermic effect of food d. resting blood sugar levels

a

Disordered Eating

A variety of abnormal eating behaviors that, by themselves, do not warrant diagnosis of an eating disorder.

Obesity

Defined as a BMI >30 kg/m^2

Overweight

Defined as a BMI between 25-29.9 kg/m^2
