Question 1

What is the main function of the intervention stage of movement analysis?

Accepted Answer

The main function of the intervention stage of movement analysis is to bring about an improvement in performance by implementing strategies to address identified movement errors or inefficiencies. Using key words and conducting a review may be part of the analysis stage, but they are not the main function of the intervention stage.

Question 2

Which of the following is not part of the intervention stage of qualitative movement analysis?

Accepted Answer

A

Question 3

Which of the following should have been done before the intervention stage of qualitative analysis of movement?

Accepted Answer

All three options should be done before the intervention stage of qualitative analysis of movement. Obtaining relevant video footage is necessary to analyze the movement, conducting needs analysis helps to identify specific areas for improvement, and preparing how feedback will be provided ensures effective communication with the athlete or individual being analyzed.

Question 4

Which of the following are also part of the Intervention stage, in addition to the provision of feedback?

Accepted Answer

Positive reinforcement, performance modelling, and guiding changes to practice are all commonly used methods during the Intervention stage of a behavior change program. Negative reinforcement is not typically used as it involves the removal of an adverse stimulus, rather than providing a reward for desirable behavior. Psychological assessment is more commonly used during the Assessment stage of a behavior change program, and changing coaches is not an intervention in itself, although it may be necessary if the current coach is not effective in facilitating behavior change.

Question 5

What is augmented feedback?

Accepted Answer

Augmented feedback refers to feedback that is in addition to or comes from a source other than the performer's own senses (such as from a coach or training device).

Question 6

Which of these correctly distinguishes between knowledge of results (KR) and knowledge of performance (KP)

Accepted Answer

Knowledge of performance (KP) includes information about the movement process, such as form, technique, and execution. Knowledge of results (KR) focuses on the outcome of the movement, such as distance, time, or accuracy. Therefore, option C is correct as it correctly distinguishes between the two concepts.

Question 7

Which of the following has been used to provide augmented feedback?

Accepted Answer

All of these options have been used to provide augmented feedback in various sports and performance domains. Forces on the pedals can be measured and displayed in real-time to provide feedback to cyclists about their technique and power output. Video recordings of the performer can be analyzed to provide feedback on specific movements or errors. Comparing the performer's video to examples of good and poor performances can also provide feedback on areas of improvement.

Question 8

Which of the following is important for successful information feedback to a coach?

Accepted Answer

All of the options listed are important for successful information feedback to a coach. Accurate and reliable results are necessary to ensure that the feedback provided is trustworthy and can be acted upon. Results that relate clearly to differences between good and poorer performance are necessary to provide actionable recommendations for improvement. Results that give information not directly observable to a coach can provide insights into an athlete's mental and emotional state, which can have a significant impact on performance.

Question 9

On which underlying 'model' of propulsion generation would correct feedback of stoke technique information in front-crawl swimming be based?

Accepted Answer

Option C suggests that the hands behave as hydrofoils, but the swimmer's body roll generates much of the observed sidewards movement. This is based on the concept of utilizing the body's rotational movement to increase propulsion. Therefore, correct feedback of stroke technique information in front-crawl swimming would be based on this underlying model. Options A and B are not relevant as they are based on different concepts of propulsion generation, and Option D is incorrect as it suggests that legs generate most propulsive force, which is not true in front-crawl swimming.

Question 10

From a sports performance viewpoint, which of these is most true about desiarable improvements resulting from the provision of augmented feedback?

Accepted Answer

Research has shown that desirable improvements resulting from augmented feedback are most likely to be retained after feedback has stopped being provided, indicating that the athlete has internalized the feedback and made lasting changes to their performance. The timing of when the improvement occurs during feedback provision varies depending on the individual and the type of feedback being provided, so options A and B are not universally true.

Question 11

Which of the following provided the best results in the retention phase of learning in the study reported in Schmidt (1991)?

Accepted Answer

Summary feedback was found to be more effective in the retention phase of learning as it allows learners to process and integrate information over time, leading to better long-term retention.

Question 12

In the study of Mononen et al. (2003), which group had significantly the best scores?

Accepted Answer

According to the results presented in the study, the 100% KP group had significantly better scores compared to the other groups in terms of vertical jump height and agility test performance. Therefore, the best choice is C.

Question 13

In the study of Guadagnoli et al. (2002), which of these statements represents their findings about accuracy distances in the two-week post-test?

Accepted Answer

The study found that the video feedback group had the greatest improvement in accuracy distances in the two-week post-test compared to the other groups.

Question 14

Which of the following best describe the key parts of an Expert System?

Accepted Answer

An expert system typically consists of three main parts: a domain-specific knowledge base, which contains the rules and information relevant to a particular field; an inference engine, which uses the knowledge base to reason and make decisions; and a user-friendly interface, which allows users to interact with the system and receive advice or recommendations. Option A correctly identifies all three of these components, while options B, C and D include incorrect or extraneous elements.

Question 15

Which of the following would be best to use as a feedback model for the Intervention stage of movement analysis to improve long jump performance?

Accepted Answer

The contractile component and the series and parallel elastic components would be the best to use as a feedback model for the intervention stage of movement analysis to improve long jump performance. The contractile component refers to the muscle fibers themselves, while the elastic components refer to the tendons and ligaments that help store and return energy during movement. By analyzing and providing feedback on the efficiency of these components, the athlete can work to improve their overall long jump performance. Options B and C do not accurately describe the relevant components involved in long jump performance.

Question 16

What is spondylolysis, an injury prevalent among fast bowlers in cricket?

Accepted Answer

The answer of What is spondylolysis, an injury prevalent among...

Question 17

Which of the following might confound the relationships reported between the mixed fast-bowling technique and low-back injuries?

Accepted Answer

The answer of Which of the following might confound the...

Question 18

Which of the following is considered to be the main feature of the mixed fast bowling technique that makes it more of an injury risk than the side-on and front-on techniques?

Accepted Answer

The mixed fast bowling technique is considered more of an injury risk because it incorporates elements that increase physical stress on the bowler's body. This includes counter-rotation (varying degrees of which have been used to classify mixed technique bowlers), changes in technique during a bowling spell (such as front-on bowlers becoming more mixed), and the inadequacy of two-dimensional shoulder angle measurements to accurately represent thorax-pelvic alignment. All these factors contribute to the increased injury risk associated with the mixed technique.

Question 19

Which of the following is considered to contribute to low back injuries in cricket fast bowlers?

Accepted Answer

All of the above factors have been shown to contribute to low back injuries in cricket fast bowlers. The mixed technique can put excessive stress on the lower back, hard surfaces can increase shock and impact forces on the spine, and abnormal biomechanics such as low foot arches can lead to altered spinal loading.

Question 20

Which of the following would not be considered a limitation of the intervention study of Wallis et al. (2002) into fast bowling injuries in cricket?

Accepted Answer

Using a bowling harness is not a limitation of the study, as it was the intervention being tested. The other options all represent limitations or findings of the study.
