MOD 2: 10/2 Weight Loss and Energy Balance

These flashcards cover important vocabulary related to weight loss and exercise science, aiming to help students prepare for their exam.

Negative Energy Balance

A state where calorie expenditure exceeds calorie intake, leading to weight loss.

Caloric Intake

The total number of calories consumed through food and drink.

Caloric Expenditure

The total number of calories burned during physical activity and body functions.

Glycogen Stores

The form in which glucose is stored in the body, primarily in muscles and the liver.

Dietary Fat

A macronutrient that is a high source of calories, with a significant impact on weight gain if consumed excessively.

Energy Deficit

The difference between calories consumed and calories burned; necessary for weight loss.

Basal Metabolic Rate (BMR)

The number of calories your body needs to maintain basic physiological functions while at rest.

VO2 Max

The maximum rate of oxygen consumption during intense exercise, indicating cardiovascular fitness.

Indirect Calorimetry

A method to estimate energy expenditure by measuring oxygen consumption and carbon dioxide production.

Crossover Effect

The point at which the body shifts from burning fat to burning carbohydrates as exercise intensity increases.

Lactic Acid

A byproduct of anaerobic metabolism often accumulated during high-intensity exercise.

Calorie Counting

The practice of tracking caloric intake and expenditure to manage weight.

Long-Term Weight Management

The ongoing process and strategies used to maintain healthy weight over a long duration.

Exercise Intensity

The level of effort required to perform physical activity, which affects how many calories are burned.

Body Composition

The proportion of fat and non-fat mass in the body, often used to assess fitness and health.

Modest Intensity Exercise

Physical activity performed at a low to moderate intensity, which can be sustained for longer duration.
