Exam 4 Fitness, Physical Performance and Ergogenic Acids Flashcards
Components of fitness
Cardiorespiratory endurance, muscle strength and endurance, flexibility and the proportion of your body that is lean tissue VS fat
Identify metabolic changes in muscles and the cardiovascular system with increased conditioning
Muscles: enhances your ability to continue repetitive muscle activity
Cardiovascular system: strengths heart muscles and increases the amount of blood pumped with each heartbeat. This decreases resting heart rate. Also increases the ability of your muscles to use oxygen and to produce ATP.
What is VO2 Max and how is it used to assess fitness
Yours body’s maximum ability to generate ATP using aerobic metabolism. The greater your VO2 the more intense activity you can perform before lack of oxygen effects your performance
Can you be fit with a BMI above 25
Yes because a high BMI can be caused by a large amount of muscle
What are the Dietary Guidelines for Physical Activity
At least 150 minutes of moderate activity or 75 minutes of vigorous-intensity aerobic activity each week or an equivalent combination of both
What level of physical activity is needed to reduce one’s risk for chronic diseases, such as heart disease
about 150 minutes a week
What level of physical activity is recommended to avoid unhealthy weight gain with age
300 minutes a week
ATP-creatine phosphate
a compound that is stored in the muscles and can be quickly converted to ADP( short term)
anaerobic energy creation
muscle glycogen and blood glucose break down into glucose that can be used for anaerobic and aerobic creation
Aerobic energy creation
amino acids from protein and fatty acids in adipose tissue and triglycerides in muscle
0-3 second activity
High ATP and low ana and aerobic
10-12 sec activity
high ATP and low ana and aerobic
4-6 mins
low ATP and high ana and aerobic
Can glucose and fat be used in anaerobic energy creation
glucose yes but fat no
Can glucose and fat be used in aerobic energy creation
yes
