Lesson 13: Applied Kinesiology Flashcards
What is kinesiology used to analyse and evaluate?
It used to analyse the vast amounts of movements that your client can do and evaluate the effectiveness/safety of a particular movement and its role towards their goals.
What should be considered when analyzing and evaluating movements and their effectiveness?
Body’s daily activities, postures and any mechanical stresses that the body undergoes in these positions.
What should a programme with integrated kinesiology look to involve?
cardiovascular endurance
proper body mechanics
neutral position alignment
muscular balance
What does the term biomechanics mean?
the application of mechanics to living organisms and the effects of applied force.
What are two areas of mechanics?
Kinematics
Kinetics
What is kinematics the study of?
Forms, pattern, sequence of movement without regard for the forces that may produce that motion.
What is kinetics?
Branch of mechanics that describes the effects of forces on the body.
From a kinesiology view point, can forces be internal and external and still modify or oppose motion?
Yes
What is an internal force?
One produced via the muscles
What is an external force?
Gravity
What is the difference between quantitative and qualitative?
Quantitative is mathematically derived whereas qualitative is subjective.
What do Newton’s law of motions provide a good understanding of the interrelationships between?
forces
mass
human movement
what would an example of a quantitative study be?
using equipment to perform precise subjective analyses of a movment
what would an example of a qualitative study be?
recording movement and showing/explaining to the client or performing in front of a mirror and giving verbal cues
what does Newton’s first law of motion, law of inertia state?
that a body/object at rest will stay at rest and a body/object in motion will stay in motion (with the same direction/velocity) unless acted upon by an external force.
What is meant by a body/object’s inertial characteristics are proportional to its mass?
That it is more difficult to move a heavy object than a lighter one.
What type of training programme has the most association with Newton’s law of Inertia?
resistance-training
What is an example of the Law of Inertia in resistance-training?
The ‘sticking point’ at the start of a bicep curl is due to the difficulty of overcoming the dumbbells inertial property of being at rest as well as the mechanical disadvantage of the human body to generate intenal forces when the elbow is fully extended.
‘a ball rolling down a hill will continue to roll unless an external force or friction causes it stop’ is an example of which of Newton’s laws of motion?
Law of Inertia
What does Newton’s second law, law of Acceleration state?
That the force acting on a body in a given direction is equal to the body’s mass multiplied by the body’s acceleration in that direction.
How does Newton’s Law of Acceleration also relate to momentum?
In that a body’s linear momentum is equal to its mass multiplied by its velocity.
According to Newton’s Law of Acceleration, what will accelerate the body to a higher velocity/speed to create more momentum for a given mass?
an additional force
According to Newton’s Law of Acceleration, for a given velocity, will linear momentum increase if the mass of the body is increased?
Yes
According to Newton’s Law of Acceleration, angular momentum has similar principle to linear momentum, but what is different about the motion performed?
The motion performed is about an axis.
