- Where is the pacemaker in the heart and what does it do?
Answer: The pacemaker (or Sino-Atrial node) is located in the Right Atrium of the heart. It is responsible for generating the small electrical impulse necessary to contract the heart and keep it beating regularly at the right speed.
An artificial pacemaker is sometimes implanted if the heart rate is too slow, too fast or not strong enough. It emits tiny electrical impulses (too small to feel), which stimulate the heart to contract.
- What is personal development?
Answer: Personal development can mean any improvement in your self. In sporting terms, you would normally associate the term with an improvement in performance or results. Performances can be measured by looking at technique (knowledge of performance - KP) or results (knowledge of results - KR). Goals can be set from this in order to achieve an overall aim.
For example, in basketball your overall aim may be to hit 10 out of 10, 3 point shots under pressure. You could practice in random pressurized situations, counting the number of successful shots out of ten (KR) and gaining feedback from a coach, peer, teacher video (KP). The next stage is to improve one technique point at a time (e.g. - arm extension), in order to get closer to your target.
I was wondering because I have seen it in a past exam paper, where the
main pulse points are and what the proper names for them are.
Be careful when testing for the pulse points. If you compress an artery too hard then you can completely cut off blood flow through that artery. If this happens then you will not feel a "pulse" in that artery and it can cause damage if sustained.
This list is not exhaustive. There are others (e.g. in the ankle and foot). However, these are the main ones:
- Femoral pulse - fold of the groin area - Femoral artery.
- Carotid pulse - fingers just below jaw and to the side of the windpipe - Carotid artery.
- Temporal pulse - on the side of the head next to the eye - Temporal artery.
- Brachial pulse - on the underside of the arm near the elbow - Brachial artery.
- Radial pulse - fingers just past 1st tendon - Radial artery (here's a tip.. raising the thumb creates a pocket which is sometimes easier to take the pulse from).
- What does the term resilience mean when referring to a gymnastic
movement?
Answer: It depends upon the context but "resilience" could mean that the skill is so well learned it will not break down in a different connection or under stress of competition. The gymnast themselves could be resilient in that they are very well prepared both physically and mentally to cope with the rigors of training and competition. |
