Student 4: High Achieved
Free throw: Knee joint = hinge joint. Movement = starts off with knee flexion which is bending
your knees. Hamstrings contract being your agonist, and your quadriceps relax being the
antagonist. This movement occurs in preparation for a jump so you can get the best range of
movement for your shot.
Layup: Hip = ball and socket. Movement = Hip flexion. Your hip flexors are the agonist they are
contracting and your gluts are your antagonist they are relaxing. And when you go up for the lay
up, its almost like your elbow and knee has a string attached to it, because when you are flexing
your shoulder and hip, when you flex your hip, your shoulder has to flex as well because thats the
hand you are going up with.
Free throw: For the free throw, the anatomical structure that can limit your performance is if you
have small muscles compared to someone with big muscles that can affect your shot because you
won’t be able to put as much force behind it. If your short or have short bones or short limbs, that
will affect how much distance your shot has.
Layup: I think in the lay up height is definitely going to advantage your performance because you
will be taller and that much closer to the hoop. You will be able to push the ball over your
opposition and you will be able to have a more accurate shot.
Free throw: For the free throw you are using Newton’s second law which is the law of
acceleration. It’s the amount of force you put behind the ball determines how far and fast the ball
will go. We are also using force summation. Force summation is using the big muscles to the
small muscles to get the best range out of our shot.
Layup: Newton’s first law, the law of inertia. An object will remain at rest until a force is upon it.
The ball is not going to move unless you have the force coming from your arms to put it into the
hoop. Why – you do this so that the ball is going to go in the hoop. So if we don’t exert our arm
muscles like our latissimus dorsi, pectorials, tricep and bicep enough, the ball will not go very far
and the ball won’t go in the hoop.
Free throw: Your height can definitely affect and limit your free throw, because if you are tall, you
are going to be closer to the hoop so you will not have to put as much force in it because your
height of release is already high, but if you are short you are going to have to put more force on it
to get it in the hoop.
Layup: I think it will affect it in a good way because you will have that more accurate shot.
During the basketball game my breathing rate changed from 12 breaths per minute to 21. This
was after 10 minutes of a 4 v 4 game of basketball. The short term effects this 10 minute game
caused were increasing my breathing rate due to me needing to take faster breaths in order for
me to get oxygen through my body. It also caused my heart rate to increase due to it needing to
beat faster to pump enough blood to my body. I also sweated. This was caused by my body
heating up when my muscles were working.
Long term effects after training hard for 6 months to a year will be my heart will be bigger and
stronger in order to take the pressure when pumping more blood around my body. My heart and
resting rate decrease as the heart has less work to do. I don’t have to breathe as much, so my
breathing rate decreases and I become more fit. My muscles get larger from increasing the size
of fibres inside each muscle by using them during training. This allows me to store more energy
(glycogen).
The energy system used in basketball are the aerobic, anaerobic and lactic and phosphate
systems. If your aerobic system is good, then you should be able to play a whole game and not
get tired as quick when running from attack to defence and vice versa. Lactic acid is used for
breakaways from one side to the other, this has a high intensity and will determine your speed
when moving. Phosphate has a very high intensity and occurs when doing jumps shots or 3
pointers.
The functional anatomy and biomechanical principles were completed verbally by the student. The
assessor asked the student the verbal questions that were completed during class time. The assessor
videoed each student, and has supplied a summary of evidence for each student. For the purpose of
providing detailed annotated exemplars, some aspects of the student work have been fully transcribed.
The exercise physiology principles were completed as a report (in class, supervised).
