Skill strengths and weaknesses Flashcards
what is the four skill strengths in her race
- good speed on her backstroke turns
- executes her backstroke start to a high standard pushing out instead of up
- she carries out a high stroke rate, moving water quickly
- conserves energy towards the end of the race to execute a good backstroke finish throwing herself at the wall
how does a fast turn affect her performance
this speed means she isn’t wasting time in the race so not loosing time against opponents allowing her to go on and win the race
what is the theory for a backstroke turn as a skill strength
a backstroke turn is a closed skill so the performer knows how to perform it and has kinaesthesia as to how it should feel. this means the skill is performed the same every time and so as she is an autonomous learner she has develop a high level of this kinaesthesia. the fact it is a closed skill means she can practice the skill as a whole in training so can be overlearned.
what is the affect of a good backstroke start on performance?
Her start enables her to get a good lead over opponents – after start she has about an arms width lead. Which is crucial in such a short race.
what theory can be linked to a backstroke start as a skill strength?
Newtons second law – acceleration. Force= mass x acceleration. demonstrated as the more force she puts against the wall the further and faster she is going to go back and build momentum for her underwaters.
what is the affect of a high stroke rate on performance
This means she is continuing to move at high speed and inevitably swim faster. The quicker and more powerfully she can move her arms through the water, the better the technique and more efficiently she moves through the water. Which is shown in the fact she swims faster than her opponents and wins the race
what is the theory linking stroke rate as a skill strength?
Lauren would have worked on this in training with access to technology that can track and help control your stroke rate. For example, Finis have an electrical stroke rate beeper that swimmers put in their hat and have to keep up with the beeps to train and adapt their bodies to have a higher stroke rate. This development has come through sport science developments at research centres like Loughborough, bath as much of this technology is all very new
what is the affect of a good backstroke finish on performance?
Having a good backstroke finish in short races like the 100m backstroke is important when shaving of those milliseconds and beating opponents. This can be the difference between winning and losing. A swimmer who can throw all their power at the wall in that final stoke is at an advantage to those who cannot.
what is the theory linking a backstroke finish as a skill strength?
Lauren recruits type 2a muscle fibers in order to have a fast explosive finish and throw herself at the wall in order to win first place. She would do lots of plyometric and strength training to increase the number of type 2a muscle fibers in order for her to benefit and have the speed for a fast finish.
what are the two skill weaknesses occurring?
- She has a weaker leg kick which mean she’s not moving as fast through the water as she can.
- Transition from underwaters to surface
what is the affect of a weaker leg kick on performance?
A strong leg kick contributes to forward propulsion, helping her maintain speed and reduce drag as her body position is more streamline so she is optimizing her stroke efficiency and can enhance transitioning during turns and finishes. This means that if Lauren had a stronger leg kick can stay at a higher speed and cover distance more quickly allowing her to be the fastest in the pool, which she was in the end.
what theory links to leg kick as a skill weakness
Effective kicking requires strong leg muscles, so improved dynamic strength allows these muscles to perform at a high level for the duration of the race without fatigue. Swimmers with better dynamic strength can maintain a powerful kick throughout the race, rather than loosing intensity as fatigue sets in. sustained power. Having a good level of dynamic strength contributes to more efficient energy use during the race, this is because the muscles are able to produce repeatedly contractions, allowing swimmers to conserve energy whilst still delivering a powerful kick.
what is the affect of transition from underwater on performance
By having a bit of water drag as she doesn’t have the smoothest transition means she’s going to loose time coming up which in a short distance is crucial. If she had smoother transitions it would make her first stroke more efficient meaning she would have more momentum coming up.
what is the theory linked to transitions from underwater
The water she traps between her body and the surface of the water creates a downwards force causing her to slow down as more drag is being created and less momentum gained
