Keys to successful Practice

Quality practice time is essential for the successful development of sports skills. To be successful in a sport an athlete must be prepared to maximise the typre, number and length of training sessions. Practice must be specifically related to the activity/game being played. Coaches should attempt to make the training as similar to the game/competition as possible i.e wearing team uniform to training. Time spent in total practice period, time spent at rest and time spent on particular skills should all vary according to the skill level of the athlete and the importance of the skill in performance; for example a tennis player might therefore have a session of practicing serving every 5-10 mins, as the player does in a game. The practice conditions should also be varied. Athletes will lose motivation if the same skills and drills are repeatedly taught in the same way. The skill itself should be analysed according to how it is used in a game and practiced in a variety of ways.


Feedback

Positive feedback is designed to make the participant feel good about his/her performance. Feedback can come from sources within the athlete. This is called INTERNAL feedback. Alternatively, feedback can come from EXTERNAL sources. This is called external feedback.
Internal Feedback: Is information received naturally from the senses as a result of movement. When passing a basketball, the athlete is aware of his/her legs, arms, shoulders and fingers as they perform the skill. They can then see it pass through the air and be caught by another person. The athlete will know straight away if the skill was successful; they perceive information about the performance without the need for equipment or devices, or advice from other people. Therefore internal feedback includes sensations such as sight, smells, touch and sound that are related to the performance.
External feedback is information that is provided from outside the performers natural sensory awareness of the immediate action. This external feedback might be the coaches voice, the scoreboard, video analysis or the cheer from the crowd.
Types of external feedback:
2 types:
  • Knowledge of results (KR)
  • Knowledge of performance (KP)

KR is info that is provided externally after the completion of the action. It is based on the outcome of the performance or what caused the outcome. KR allows the athlete to correct the action next time.

KP is info that is received either internally or externally concerning the movement executed. KP does not inform about the movement success (as KR does). Rather, KP informs about the performance itself, i.e how it looked

Timing of Feedback

Concurrent feedback: Feedback received during the performance. The athlete can respond to this type of feedback.

Delayed feedback: Feedback provided after the performance and therefore the athlete cannot respond to it

Research task

1. A closed skill is a skill which is controlled by the individual and is done in a stable and predictable environmnet. E.g. Throwing a ball inside a gym.
An open skill is not controlled by the individual and is performed in unstable, unpredictable conditions. E.g. Catching a ball outside on a windy day.

2. Fine motor skills are movements which require the movement of only small muscle groups. E.g. Throwing a dart. Gross motor skills require movement from large muscle groups. E.g. Kicking a football.

3. Discrete skills: Skills which have a disinct beginning and ending.
Continuous skills: Skill which involve the same movement pattern over and over again. The individual can determine when to stop
Serial skills: This is a group of discrete skills which have been intergrated into a sequence and are performed together (in quick succession)

4. Sport: Basketball
Shooting: Closed but defender makes it 'more open': Gross: Discrete
Catching: Open: Gross: Discrete
Passing: Closed: Gross: Discrete
Layup: Closed: Gross: Serial
Running: Closed: Gross: Continuous
Defensive slides: Closed: Gross: Continuous

Characteristics of the learner

Each human has unique physical, emotional and social characteristics. The way in which people learn, perform and think affect every aspect of their lives. These individual differences include inherited, social and emotional factors and they account for the variability in the learning of motor skills.
Inherited Factors: Affecting skill acquisition include gender, race, somatotype (body shape), muscle fibre composition, information processing capacity and aptitude for the activity. Skill acquisition depends on the level of keenness, confidence, competitiveness, self esteem, relations with others and even levels of agression. These personality traits are enhanced as involvement in the activity continues.
Skill acquisition can be influenced by the reasons for participation, the level of aspiration, the degree of enjoyment, the effort put into the activity and the readiness of the participant to learn. Those athletes who are confident about their abilities, or their ability to improve abd learn, will develop skills faster than those who are not. This self-confidence in athletes is sometimes noted as "ego." Ego can be a good tool for coping with stress and throwing others off their game

Stages of Skill Acquisition
The ability of individuals to experience, learn & refine motor skills greatly affects their ability to perform any physical activity. It is important for athletes to know the processes that individual undertake when learning a new skill & how these processes can be adapted to help individuals learn new skills quickly and easily.
Learning skills
There are three stages of learning:
• Cognitive learning: learning by receiving knowledge & information
• Affective Learning: learning on a social level (i.e. by developing ideas about sportsmanship & fair play)
• Motor Learning: learning by acquiring physical motor skills
A skill can be defined simply as an act or task. We can also use the term to describe someone’s ability, for example, Jimmy Bartel is a skilled footballer.
In your view, how can you tell (visibly) if someone is skilled at their particular sport? Give an example.
Lebron James is a skilled basketball player because he has incredible athleticism for a person of his build and has excellent basketball skills. He has won the Most Valuable Player award in the NBA and makes all skills required in the game look easy.



Becoming a skilled athlete depends on 3 factors:
1. Stages of skill acquisition
2. Characteristics of the learner
3. Environment

1. The stages of skill acquisition
Learning involves practice and time. Over time and with practice, someone who us a beginner will progress through various stages to become a skilled performer.
1st Stage: Cognitive Stage: this stage is characterised by thinking. In this stage the learner forms a cognitive picture of the skill and what is required to do it. The movements in this stage are jerky and dis-jointed and usually poorly timed. Performance is inconsistent, with a large number of errors – the learner will know something is wrong. When learning to play a golf shot, a learner will probably hit the ground a lot and miss the ball completely. Fortunately, this stage is usually quite short, and with greater practice and though, the learner will progress and make rapid gains in proficiency. In this stage, a coach should teach simple, fundamental skills by demonstrating, modelling and giving clear instructions. Instructions should be brief and should only focus on a couple of things at a time. Important points:
• Has the learner got an appropriate level of strength/conditioning to perform this skill?
• Break the skill into parts
• Keep instructions clear and simple
• Provide instant feedback

2nd Stage: Associative Stage: In comparison to the cognitive stage, the associative stage is quite long. In fact, a person may never move beyond this stage. In this stage, the fundamentals of the skill have been learnt and performance has started to become less variable and more consistent. There are fewer errors because the athlete has developed the ability to detect and correct errors (through practice and feedback). Movements become coordinated as the athlete learns to use environmental cues for timing. Anticipation develops, and smoother, less rushed skills result as the individual needs to think less about the skill and can rely more on "muscle memory." There is a marked improvement with decreased energy expenditure. Important notes:
  • Coaches should communicate well and individualise feedback
  • Errors should be identified and corrected
  • Teach the movement pattern first - then introduce game-like situations

3rd Stage: Autonomous Stage: After much practice and experience, the skill becomes habitual or automatic. In this stage, improvements come slowly but there is good consistency in performance. Most of the skill can be performed without thinking because the athlete requires less attention to the basics. Instead, he or she can give more selective attenion to higher-order cognitive activities such as game strategies or evading the opposition. With minimal errors and good timing, the athlete develops self confidence and risk-taking in performance situations. In this stage of skill acquisition, the practice sessions need to be well organised to ensure the best improvements. The athlete must be highly motivated and given regular feedback. Training should attempt to simulate the actual performance conditions.

2012 Plyometrics






Plyometric Training
1. What is plyometric training?
The method of training that seeks to enhance the explosive reaction of the individual through powerful muscular contractions because of rapid eccentric contractions.
2. Drop Jumping
This exercise involves the athlete dropping (not jumping) to the ground from a raised platform or box, and then immediately jumping up








Medicine Ball: Another means of increasing upper body strength popular with throwers is to lie on the ground face up.











Benefits of Plyometrics
· Increased explosive muscular power
· Increased speed
· Increased muscular endurance
· Enhancement of fast twitch muscles

This would be helpful for sports such as:
· Basketball
· Athletics
· Football
· Soccer
· Tennis
· Badminton
· Squash

I do not currently involve plyometrics in my weekly training although I have done in the past.

It would be beneficial to include plyometric exercises into my weekly schedule as it would help to improve my explosiveness and speed. This would benefit my basketball greatly.
