QUIZ QUESTIONS!!! 4-7 Flashcards
When you are considering whether the athlete (performer) has optimal stability for applying or receiving a force, you can ask yourself the following questions:
a.
Is the BOS too narrow (small) or too wide (large) for the context?
b.
All of these questions would be appropriate to ask.
c.
Is the athlete standing too tall (raising their COG) instead of squatting down (lowering their COG), or vice versa for the context?
d.
Is the COG too close to the edge of the BOS when it should be more central, or vice versa for the context?
e.
Is the BOS extended in the direction that it should be for the context?
b. all of these questions are appropriate to ask
Taken from your readings, “Athletes in many sports are taught specific techniques to extend the area and time over which forces act on their bodies. By doing this they avoid injury and reduce to comfortable levels the pressure exerted on them. Ski jumpers perform a telemark landing after flying through the air, by flexing their legs with one leg forward and one leg back which lengthens the time that the impact force of landing is applied to their bodies.” During this landing phase, describe the most appropriate kinematics and kinetics taking place:
a. knees straightening (extension), concentric knee extensors
b.
knees bending (flexion), concentric knee flexors
c.
none of the answers are correct
d.
knees straightening (extension), eccentric knee flexors
e.
knees bending (flexion), eccentric knee extensors
e. knees bending, (flexion) eccentric knee extensors
Force Absorption Concept A2 encourages a performer, when receiving or absorbing a force, to “maximize the absorbing surface area” so that …
a.
the action force into the receiving surface is reduced (on any one part of the tissues involved) since there is more tissue included in the larger surface area.
b.
the force taken on by any one unit area of the receiving/absorbing surface area is reduced.
c.
all of the answers are correct.
d.
the force can be spread out over a greater contact or receiving surface area.
c. all of the answers are correct
Burkett (2019) discusses the characteristics and mechanical principles of a football tackle. Which mechanics (mechanical) principle helps to explain what occurs after contact is made between the tackling player and the opposition?
a.
The impact forces generated within a tackle can cause high velocities, and when the fast-moving anatomical segment makes a rapid stop, the extremely high deceleration can be greater than the safe acceleration of the musculoskeletal system of the human allows, resulting in injury.
b.
The final direction following the tackle collision depends on the resultant force generated by each player, where the net resultant force will be the sum of their original inertia before impact.
c.
To transfer the inertial forces effectively, the tackling player must make contact with the opposition. Getting into a safe position with the head well clear of the impact zone is paramount. Doing this requires a technically correct combination of position and acceleration to put the tackling player into the desired position.
d.
The stable base of support is generated with placement of the feet as far apart as possible. This stance allows a greater range of movement of the line of gravity within the base of support. The ability to generate a tackling force can also be enhanced if the base of support is greater in the direction of travel, because this stance also allows greater torque to be produced.
e.
All of the mechanics (mechanical) principles given help to explain what occurs after contact is made between the tackling player and the opposition.
b. The final direction following the tackle collision depends on the resultant force generated by each player, where the net resultant force will be the sum of their original inertia before impact.
Force can be reduced or absorbed by “giving with” the oncoming force or “spreading out” the oncoming force. Giving with and spreading out the oncoming force can BOTH be done by simply bending the joints as the impact occurs.
True
False
False
When an object or receiving surface compresses upon impact, that area of impact provides a cushioning effect that also serves to increase the time and distance over which the materials involved can receive the impact.
True
False
True
our course readings suggest that in your analysis of sport performance, you may notice that inexperienced athletes apply force in many directions and much of their muscular effort makes no contribution to their performance. For example, if a young shot-putter complains that ‘putting the shot’ bends their fingers backward, you may want to observe/examine:
a.
the strength of their finger muscles which may be inadequate
b.
whether they are (or are not) applying force directly in line with the centre of gravity of the shot
c.
all of the answers would be appropriate
d.
whether they are simply applying too much force to the shotput
e.
whether their manipulation of stability and balance is causing them to tip over
b. weather they are (or are not) applying force directly in line with the centre of gravity of the shot

Body Management concept B6 states “Slide sideways or use crossovers in a diagonally forward or backward direction to efficiently move the body through space if the distance to be covered is minimal or if the body needs to remain facing the immediate objective.” Successful performances in fielding games, such as baseball or cricket, would employ this concept exclusively because it takes too much time to readjust to the forward position and then run forward to cover the distances required for all of gameplay.
True
False
False

Body Management Concept B1 states “generate & employ a ready position conducive to the contextual requirements” in order to allow a player to get a faster start to out-manoeuvre the opponent, to gain possession of the ball or object, or to get into a desirable position to project an object. Ready positions, when the direction of movement or the oncoming force is unknown, are best achieved by:
a.
All of the answers are correct
b.
placing the feet shoulder width apart and directly parallel to one another (favoring frontal plane stability)
c.
placing the feet in a position where one foot is forward and one foot is back (favoring sagittal plane stability)
d.
keeping the hips, knees, ankles, flexed and ready to immediately push in the opposite direction of the intended direction of travel, allowing for quick pivot and push off when needed, and as necessary for the given context.
e.
shifting the COG & LOG towards the front edge of the BOS.
d.
keeping the hips, knees, ankles, flexed and ready to immediately push in the opposite direction of the intended direction of travel, allowing for quick pivot and push off when needed, and as necessary for the given context.
A recurring key theme in body management is a performer’s ability to manipulate the COG & LOG in relation to the BOS in order to create stability and mobility in the desired direction in accordance with the contextual demands of the movement for successful performance.
