Chapter 6 Flashcards
Structured, planned physical activity, often to improve fitness. Protects brain health and cells that line blood vessels.
Exercise
Ability of the body to respond to physical demands placed upon it.
physical fitness
The ability to perform specific skills associated with various sports and leisure activities. Include agility, speed, power, balance, coordination, and reaction time.
Skill-related fitness
The ability to perform daily activities. Example: shopping for groceries
Health-related fitness
Activity that requires any type of movement that is necessary for good health. Too much of this may make you susceptible to injury.
Physical activity
True or False?
Weight-bearing exercises such as walking and weight training are essential for bone growth. Non-weight-bearing exercises such as swimming and bike riding does nothing for bone growth.
True
Exercise stimulates growth of new cells in what 2 parts of the brain?
Hippocampus and frontal cortex
Part of the brain where learning is centered
Hippocampus
The center for decision making and planning
Frontal cortex
What encourages brain cells to branch out, join together, and communicate with each other in new ways?
Exercise
Increases the creation of mitochondria, cells energy furnace, in muscles and the brain. This impact on mitochondria likely explains why you feel that mental edge after performing this exercise. Increase the SIZE of LDL’s.
Aerobic exercise
After exercise, it increases this neurotransmitter which is important for memory
Acetylcholine
Exercise may increase levels of this which is a protein that offsets atrophy of brain cells.
brain-derived neurotropic
True or False?
Green exercise is when you perform exercises outside in nature. Blue exercise is when you exercise by the ocean.
True
Current research suggests that exercise removes glucose from the blood by stimulating muscle cells to make a protein called PGC-1a. This finding may provide a valuable new pathway for treating people with what?
Diabetes
Defined as activity that noticeably accelerates the heart rate and causes you to break a sweat. Example: A brisk walk, housework, yoga, golf (no cart).
Moderate-intensity activity
Causes rapid breathing and substantial increase in heart rate. A broad indicator of performing this form of activity is when you’re able to say only a few words without taking a breath.
Example: running, volleyball, basketball
Vigorous -intensity activity
Performing daily activities. Example: laundry, darts, playing cards, canoeing.
Light-intensity activity
Exercise should be done in increments of how many minutes?
10
Body’s ability to adapt to increasing demands by becoming more fit. The more you exercise, the fitter you become.
Fitness training
4 dimensions of exercise sessions that affect overload: (FITT) +P
Frequency: numbers of sessions per week
Intensity: level of difficulty
Time: duration
Type: type of exercise in each exercise
Progression: gradually increase demands on your body overtime. If you’re in your 20’s, you should up your workload after 14 days; 30’s would 16 days and so on.
The ability of the heart and lungs to efficiently deliver oxygen and nutrients to the body’s muscles and cells via the bloodstream. Increases the amount of blood pumped with each heartbeat. Involve movement of whole body such as running, swimming, and aerobic dance.
Cardiorespiratory fitness
What is the average resting heart rate of a fit person?
55-65 bpm
When you do the same cardio training every week and your body eventually runs on empty. Can cause fatigue, mood swings, immune system dysfunction, and injury.
Overtraining syndrome
The point at which you are stressing your cardiorespiratory system for optimal benefit not overdoing it.
