Who is a personal trainer?
An individual who educates and trains clients in the performance of safe and appropriate exercises to effectively lead their clients to optimal health.
What percentage of Americans remain sedentary?
25%
List 8 areas of knowledge a personal trainer should know.
Exercise programming, exercise physiology, functional anatomy and biomechanics, assessment and fitness testing, nutrition and weight management, basic emergency procedures and safety, program administration, human behavior/motivation.
Where does the energy come from that fuels our physical activity?
Carbs, protein, and fats.
What is homeostasis?
The automatic tendency to maintain a relatively constant internal environment.
List an define the two phases of metabolism.
Anabolism - the building up of complex chemical compounds from simpler compounds
Catabolism - the breaking down of complex chemical compounds into simpler compounds
What is BMR and how does it relate to our metabolic set point?
The basal metabolic rate is the homeostasis for ones own caloric need for daily activity determined by ones own metabolic set point.
What is the relationship between a kilocalorie and a calorie?
A kilocalorie is the measurable unit of a calorie which represents a unit of heat (energy) released from food.
What is the thermogenic effect?
The heat liberated from a particular food is a measure not only of it energy but also as its tendency to be burned as heat.
What is the respiratory quotient?
A method of determining the “fuel mix” being used giving us a way to measure the relative amounts of fats, carbohydrates, and proteins being burned for energy
What is ATP?
The molecule that stores energy in a form that can be used for muscle contractions.
What is the ATP/CP pathway?
ATP and CP provide anaerobic sources of phosphate-bond energy, the energy liberated from hydrolysis of CP re-bonds with ADP and Pi forming ATP.
What is the glycolytic pathway?
Glucose is broken down to produce energy anaerobically.
What is the oxidative pathway?
Oxygen combines with lactic acid resynthesizing glycogen to produce energy aerobically.
List the levels of organization in the human body.
Chemical: atoms and molecules Cellular: organelle and cells Tissue Organ Body system Organism
What are the cellular components that make up a cell?
Plasma membrane Nucleus Ribosomes Endoplasmic reticulum Golgi apparatus Lysosomes Mitochondria
What are the four types of tissues in the body?
Epithelial
Connective
Muscle
Nervous
What are the systems that make up the body?
Integumentary Skeletal Muscular Nervous Endocrine Circulatory Respiratory Digestive Urinary Reproductive
What is the respiratory system and it’s role?
Consists of lungs and air passageways, supplies oxygen to the body and remove carbon dioxide.
Explain the circulatory system and it’s role.
Consists of the cardiovascular system and lymphatic system and serves as the transportation system of the body.
What are the components of blood?
Plasma
Erythrocytes
Leukocytes
Platelets
What is the role of the heart in training?
Takes oxygen laden blood from the lungs and distributes it to the body while also removing carbon dioxide from the blood.
Explain the digestive system and it’s role.
Consists of digestive tract and glands that secrete juices into the digestive tract. Responsible for the breakdown of food and waste elimination.
What is the nervous system and it’s two major parts?
Comprised of the brain, spinal cord, sense organs, and nerves. Regulates all other systems.
Central nervous system: the brain and spinal cord. Receives messages and after interpreting sends instructions to the body.
Peripheral nervous system: relays messages from the CNS to the body and to the CNS from the body.
