PATHFIT MIDTERM (ALL TOPIC) Flashcards
Are tightening (contractions) of a specific muscle or group of muscles. Muscle contraction without motion.
Isometric Contraction
Benefits of Isometric Contraction
They are useful exercises for activating many muscle fibers at once.
They require less practice to perform exercises.
maintain constant tension in the muscle as the muscle changes length
Isotonic Contraction
Benefit of Isotonic Contraction
Stronger Muscle, Stronger Bones, Weight loss, Increase Muscle Mass, Better Cardiovascular Health
2 Types of Isotonic Contraction
Concentric Contraction
Eccentric Contraction
muscle tension rises to meet the resistance then remains stable as the muscle shortens. (away from the land) Insertion moves toward the origin.
Concentric Contraction
the muscle lengthens as the resistance becomes greater than the force the muscle is producing. (Forward to the land) Insertion moves away from the origin.
Eccentric Contraction
Functions of Muscular System
Producing movements.
Maintain posture.
Stabilizing joints
Generating heat
4 Common Muscle Characteristics
Contractility
Extendibility
Elasticity.
Excitability (response to stimuli).
3 Types of Muscle
Visceral or Smooth Muscle
Skeletal Muscle
Cardiac Muscle
internal organs (involuntary). Responsible for many tasks, including movement of food along intestines, enlargement and contraction of blood vessels, size of pupils and many
Visceral or Smooth Muscle
(voluntary) responsible for body movement.
Skeletal Muscle
(involuntary) responsible for the contraction of the heart
Cardiac Muscle
is a system that responsible for the movement of the human body. Each of these muscles is a discrete organ constructed of skeletal muscle tissue, blood vessels, tendons, and nerves.
Muscular System
Method that has you time out the length of each phase (lowering. lifting, and pausing) of each rep and, ultimately, each set in order to promote the greatest amount of muscle gain.
Time Under Tension
The amount of time a muscle is held under tension or strain during an exercise set
Time Under Tension
Formula of TUT
Formula:
4+1+1+0 = Ans x how many reps
Ideal Ranges for Timer Under Tension
- Muscle Strength or Power - 4 to 20 seconds.
- Muscle Size or Growth- 40 to 60. seconds.
- Muscle Endurance 70 to 100 seconds.
Benefits of TUT
help you to get more out of your exercise routine
leads to muscle growth, the harder you make your muscles work, the better results you’ll see
stronger muscles, bigger, enhance muscular control, improve bone mineral density, and lower body fat percentage.
body will look and feel more toned, and you may experience more muscle soreness
can stimulate awareness and concentration
When you pay attention to your movement, you can focus on proper breathing techniques, alignment, patterns and movement
helps to develop muscular control and correct posture while stabilizing your body in a way that prevents injuries.
used to calculate target heart rate (THR) during exercise
KARVONEN Formula
Helps individuals exercise safely and effectively based on their fitness level
KARVONEN FORMULA
Formula of KARVONEN
Formula:
220 - Age = MHR
MHR - Resting Heart Rate = Ans
Ans x Max Intensity + RHR = BPM
- focusing on a long and relaxing exhale and proper inhale to use breathing to set the position of our ribcage and pelvis. This is a lower threshold activity.
Breathing
a forceful holding of breath that uses a higher threshold strategy to stabilize the thorax and pelvis.
