Section 18B - Physical Fitness and Fitness Components Flashcards
Why is being physically fit more than just passing the Air Force Fitness Assessment?
Being physically fit ensures every Airman can properly support the Air Force mission while performing at optimal capacity.
The fitness program’s goal is to motivate year-round physical conditioning. What does the program emphasize?
Total fitness. (This includes proper aerobic conditioning, muscular, fitness training and healthy eating.)
What the five major components of fitness?
1) Cardiorespiratory endurance; 2) body composition; 3) muscular strength; 40 muscular endurance; and 5) flexibility. (Warm-up and cool-down are also essential components of a complete physical fitness program.)
What is cardiorespiratory endurance?
Sometimes called aerobic fitness, it is the ability to perform large muscle, dynamic, moderate-to-high intensity exercise for prolonged periods.
Body _______ measures your relative amounts of fat and fat-free tissue.
Composition
What is muscular strength?
The maximum force generated by a specific muscle or muscle group.
What is muscular endurance?
A muscle group’s ability to contract repeatedly over a period of time to cause a muscular fatigue.
_______ is the maximum ability to move a joint freely, without pain, through a range of motion.
Flexibility
What four principles should a successful cardiovascular exercise program employ?
The principles of 1) frequency; 2) intensity; 3) duration; and 4) mode.
Effective cardiorespiratory conditioning is best accomplished with _____ to ______ adequately intense workouts per week.
Three to five
Effective cardiorespiratory conditioning is best accomplished with ____ to ____ adequately intense workouts per week.
Three to five.
Fitness leaders must beware of the dangers of ____ since the risk of injury increases with increasing workout duration and intensity.
Overtraining.
Improvements in cardiovascular fitness are directly related to the ____ of the exercise being performed.
Intensity.
What is the minimum training intensity required in an exercise session?
50% of Volume of Oxygen (VO2) max, sometimes referred to as the “training threshold.”
Target Heart Rate (THR) corresponds to an intensity sufficient to achieve cardiorespiratory improvement. (T/F)
True.
In cardiovascular training, how do you calculate your Target Heart Rate (THR)?
Subtract your age from 220. Then multiply by .7 to find the bottom THR and by .9 to find the top THR.
A Target Heart Rate (THR) of 70% to 90% of one’s theoretical Maximum Heart Rate (MHR) is equivalent to ____ to ____ of one’s Volume of Oxygen (VO2) max.
50 to 85%.
____ is the time spend exercising with the most benefit occurring in the Target Heart Rate (THR) zone.
Duration. (The more intense the activity, the short the time needed to produce or maintain the training effect.)
Only sustained activities requiring a large amount of exercise using large muscle groups will improve cardiovascular fitness. Give several examples.
Running, rowing, jogging, vigorous walking, jumping rope, stationary cycling, swimming and stair climbing.
Successful muscular strength and endurance programs employ what five principles?
The principles of 1) specificity; 2) regularity; 3) recovery; 4) balance; and 5) variety.
The principle of ____ dictates you provide resistance to the muscle groups that need to be strengthened.
Specificity. (Strengthening muscles used in work-related movements can improve job performance.)
The principles of specificity states: If an Airman wishes to improve performance for a work-related task, then strengthening the identified muscles will ensure maximum carryover values for his other ____ tasks.
Warrior tasks.
Exercise must be done regularly to produce a training effect. How many workouts per week produce optimal gains in strength?
Three workouts per week.
Can an Airman maintain a moderate level of strength by doing proper strength workouts only once a week?
Yes, for a short period of time, if he or she has already established a strong baseline level of muscular fitness.
An Airman who exercises three times per week achieves optimal muscle strength gains when exercising different muscle groups at each workout. (T/F)
False. (Gains will be minimal as the principal of regularity is violated.)
How many times a week should an Airman exercise the same muscle group?
A minimum of two time per week.
Why should there be at least a 48-hour recovery period between working the same muscle groups?
So the muscles have time to adapt.
Consecutive days of hard resistance training for the same muscle group can be ____.
Detrimental. (Strength training can be done everyday, but only if the muscle groups are rotated so the same muscles are not trained consecutively.)
Normally, the recovery between sets in muscular strength training should be between ____ to ____ seconds.
30 to 180.
The principle of ____ states that a strength-training program should work all major muscle groups in both the upper and lower body.
Balance.
The principle of balance indicates that you should work opposing muscle groups during strength training. Why?
It ensures good muscle strength and may reduce the risk of injury. (For example, follow an overhead press with a lat. pulldown exercise.)
In a strength-training program, exercises should target larger muscle groups first. (T/F)
True. (If smaller muscle groups are worked first, they will be exhausted and too weak to handle the resistance needed to overload the large muscle groups.)
What is the principle of variety in strength and endurance programs?
Enhance results by using different types of equipment and exercises and altering volume and intensity.
To enhance variety, change your muscular conditioning to ____-resisted exercises or another form of resistance training.
Partner-resisted.
While adding variety to a strength-training program can be beneficial, why should Airmen avoid frequent wholesale changes?
They may become frustrated if they do not have enough time to adapt or see improvements in strength.
Prevent injury and muscle soreness with a good ____ at the beginning and ____ at the end of exercise.
Warm-up and cool down.
During the warm up, perform slow joint rotation exercises. This will help increase the joint’s ____ of ____.
Range of motion. (Work each major joint for 5 to 10 seconds.)
The preferred time for flexibility stretching is before the exercise session. (T/F)
False. (Overstretching prior to session can compromise joint integrity.)
When is the best time to improve your flexibility by stretching?
After exercising, when your muscles are warmest.
Hold stretching positions for ____ to ____ seconds during cool-down.
10 to 15 seconds. (Relax the stretch, then repeat for maximum benefit.)
What are the two most important factors in maintaining a positive body composition and losing excessive body fat?
Exercise and diet.
