3. Understanding Human Movement Flashcards
How does the human body develop?
The human body develops in response to stresses placed on its individual systems
What is the best way to functionally prepare the body?
Train the way in which the body moves favouring integration over isolation
What is movement?
Movement is the result of muscle force, where actions at one body segment affect successive body segments along the kinetic chain.
What forces affect the body?
External loads, gravity pulling down, reactive forces pushing upward through the body
Joint stability
The ability to maintain control joint movement or position, achieved through muscles, ligaments and joint capsules.
Joints Scapulothoracic Lumbar Knee Foot
Joint mobility
The range of uninhibited movement around a joint or body segment
Joints Glenohumeral/ shoulder Thoracic Hip Ankle
How do joints demonstrate varying levels of stability and mobility?
Depending on their function they tend to favour one over the other.
Lumbar spine has some mobility [15° of rotation] but most stability
Thoracic spine is more mobile
Scapulothoracic joint is more stable and provide solid platform for pulling and pushing
The stability of the foot is unique because it varies during the gait cycle. Stable at push off and mobile at pronation
What are the three planes of motion?
TFS
Transverse, frontal, sagittal
Transverse plane
Superior is toward the head: upper
Inferior is toward the feet: lower
Includes primarily rotational or twisting movements where the rib cage goes in one direction while the pelvis moves in the other
Yoga and Pilates twists, abdominal core exercises, bicycle crunches
What is medial?
The part closest to the middle of the body
What is lateral?
Part closest to the outside of the body
Frontal plane
Ventral is to the front: anterior
Dorsal is to the back: posterior
Includes movement sideways: lateral
Abduction, adduction
Lateral spine flexion
Ankle inversion and eversion
Jumping jacks or lateral lunch
Sagittal plane
Right and left side of the body
Includes movement front and back
Flexion of elbows shoulders knees hips and spine
Extension of shoulders knees hips and spine
Plantar/ankle flexion
Dorsiflexion
Indoor cycling classes
Supine exercises
Squats and lunges
What are the five primary movement patterns?
Bend and lift Single leg e.g. walking Upper body pushing Upper body pulling Rotational movements
BSUUR
What is balance in group exercise?
Cardio, strength, flexibility, balance and agility
It includes:
Neuromuscular, training, programming
What are the neuromuscular components of balanced group exercise?
Stand on one leg
Stand equally supportive on both feet
Quadruped balance
Neutral pelvic position and spine posture
Using unstable surfaces
Raising one knee or foot in plank position
What are the training components of balanced group exercise?
Work both sides of the body
Bilateral training
Transitional and reversible
Repeated on both sides and In both directions
Incorporating different styles of fitness
What are the programming components of balanced group exercise?
Consider opposing muscles: agonist and antagonist
Considered varying planes of motion
Incorporate exercises in all three planes of movement
Which food sources do our energies come from?
Carbohydrates
Quick energy
Easy to break down
Stored as glucose
Fats
Potential energy
Stored as triglycerides
How does the body create energy?
It breaks down the chemical bonds in the stored energy releasing adenosine triphosphate ATP
What determines the fuel sources used during exercise?
Intensity and duration, there is an inverse relationship between intensity and duration
The more intense the workout the less time participants are able to maintain the intensity
What is used when exercising extreme intensity for just seconds?
A small amount of creatine phosphate via the phosphagen system
E.g. sprinting as fast as possible, only sustainable for a few seconds
What is used when people work at hard intensities for a few minutes?
They use carbohydrates stores via the glycolytic and anaerobic system which produces ATP without oxygen
E.g. high intensity intervals lasting 1 to 2 minutes with a recovery to breath oxygen and replenish the muscles
What is used when people work at moderate and low intensities for longer than a few minutes?
A combination of carbohydrates and fats are used with oxygen to produce ATP via the aerobic system.
E.g. swimming, cardio classes and step classes
What is the three zone intensity model?
A way to gauge appropriate exertion during cardio respiratory activity.
Zone one: low to moderate, can talk comfortably
Zone two: moderate to vigorous, talking a challenge but still possible
Zone three: Vigourous to very vigorous, talking is not comfortable
What does a person cross when moving from the zone one through to zone 3?
They pass through the first ventilatory threshold and onto the second ventilatory threshold
What are the two components of the ACE integrated fitness training model?
- Functional movement and resistance training
2. Cardio respiratory training
What are the four phases of the ACE integrated fitness training model?
Function, health, fitness, performance
