Unit 7 Fitness Trackers: Module 3 Flashcards
(22 cards)
What are the components of the cardiovascular system?
Arteries, veins, and capillaries.
How does regular exercise affect blood pressure?
Helps regulate blood pressure and prevent heart disease.
What is the leading cause of death in the United States?
Heart disease.
What type of pressure readings are used to assess blood pressure?
Systolic pressure and diastolic pressure.
What is considered optimal blood pressure?
120/80 mm Hg.
How does regular exercise influence heart rate?
Lowers resting heart rate and increases VO2 max.
What does VO2 max measure?
The maximum volume of oxygen the body can use.
What factors do fitness trackers use to estimate VO2 max?
Age, sex, weight, and resting heart rate.
What are the stages of sleep?
Light sleep, deep sleep, and REM sleep.
What brain waves are associated with different sleep stages?
Alpha, beta, theta, and delta waves.
What can sleep deprivation lead to?
Memory issues, mood changes, difficulty regulating hormone levels, and lack of coordination.
How much exercise per week can improve sleep duration and quality?
A minimum of 150 minutes.
What substances can interfere with normal sleep cycles?
Drugs and alcohol.
What do muscles use for energy during exercise?
Glycogen, triglycerides, glucose, and fatty acids.
What is the difference between aerobic and anaerobic pathways?
Aerobic pathways require oxygen; anaerobic pathways do not.
What does the creatine phosphate pathway do?
Quickly generates ATP without oxygen.
What is fermentation in the context of exercise?
Converts glycogen to lactate anaerobically, releasing small amounts of ATP.
What is the most efficient energy production pathway?
Cellular respiration.
What are fast-twitch muscle fibers designed for?
Strength, helpful in short-distance running and weightlifting.
What are slow-twitch muscle fibers beneficial for?
Endurance sports like long-distance running and swimming.
What future advancements may fitness trackers include?
EKG data, blood pressure monitoring, hydration detection, and continuous blood sugar monitoring.
What will future advancements in fitness trackers assist with?
Personalized medicine and providing more data for diagnosis and treatment.
