the primary fuel during endurance exercise is - fatty acids the human body consists of - chemicals, cells, tissues Metabolism can be categorized in the following phases - catabolism & anabolism BMR stands for - basal metabolic rate A 30-minute jog would rely most heavily on which energy pathway? - oxidative The automatic tendency to maintain a relatively constant internal environment is called homeostasis. - true About 98% of the human body is composed of only six elements: oxygen, carbon, hydrogen, nitrogen, calcium and phosphorous. - true Mitochondria are known as the powerhouse of the cell. - true The heart, arteries and veins are part of the circulatory system. - true The ATP/CP pathway is considered aerobic metabolism. - false Non-oxidative glycolysis is reliable for: - Up to 2 minutes of ATP production The primary fuel during endurance exercise is - muscle glycogen The main purpose of hormones is to: - Alter the rate of synthesis of your cellular protein, Change the rate of enzyme activity, Change the rate of transport of nutrients through the cell wall The main purpose of the digestive system is - the breakdown of foods and waste elimination. The main purpose of the respiratory system is: - To supply oxygen to the body, To eliminate carbon dioxide in the body, To regulate the body's pH balance The average human adult skeleton has - 206 bones There are 80 bones in the axial skeleton. - true This type of joint permits a wide range of movement in ONE plane. - hinge joints Tendons connect bone to bone. - false Tendons: - Are extensions of muscle fibers, Connect muscle to bone The points of muscle attachment are known as the - insertion, origin The origin is the distal attachment of a muscle - false These sense organs measure the strain in a muscle and can be used to pre-set the tension of muscles. - Muscle spindles Myofibrils are constructed of overlapping strands of protein polymers called - actin and myosin What is the byproduct of glucose and glycogen metabolism (glycolysis) in anaerobic muscle energetics? - Lactic Acid Type I muscle fibers are aerobic. - true Type II muscle fibers are slow twitch fibers. - false Cardiovascular exercise results in: - Mitochondrial adaptations and Capillary capacity adaptations Muscular hypertrophy is a(n) - increase in muscle fiber size Kinesiology is - he science or study of movement, and the active and passive structures involved An example of an antagonist muscle is - riceps during a biceps curl The angle of pull is - the variance of force at different points in the range of motion of an exercise A lever is defined as - a rigid bar that turns around an axis of rotation or fulcrum Biomechanics is the study of: - Movement Musculoskeletal deviations can result in - poor muscle balance, poor flexibility, improper spinal alignment Excessive lateral curvature of the spinal column is known as: - Scoliosis What should be of prime focus in all fitness activities? - Posture
