Introduction
Table Tennis developed in the end of the 19th Century in England. Table Tennis was first introduced as a sports branch in the 1988 Seoul Olympic Games and is highly popular in Asia and Europe. Only a few studies have been conducted about this sports branch in terms of the normative population (Sindik, 2013; Zhang, 2012) and the population of persons with intellectual disabilities (Van Biesen et. al., 2014; Van Biesen et. al., 2010).
Although it has not been researched much, there are a number of research studies engaging in Table Tennis in general (e.g. Sergio et. al., 2002; Raab, 2005; Zhang, 2012; Sindik et. al, 2013; Silva et al, 1982 ).
Literature Review
Sport in general and branches which involve rapid ball movement in particular require the athlete to make fast decisions regarding how to hit the ball and which movement to choose in order to react to the ball toward him or her. This means the game consists of two main components: technique and tactics (Abel et al, 2004; Raab et. al., 2005; Zhang et. al., 2012). Vickers (2003) proposed a training program which includes repetitive practice of the skill and dividing the skills into stages of movement, where learning occurs from the easiest aspect to the hardest ones, based on the assumption that movement is learnt from the declarative aspect to the procedural one (Vickers, 2003). Vickers (2003) designed a Table Tennis program which integrates the cognitive aspect of decision-making and the technical aspect of learning the skill, assuming that movement or training must be as realistic as possible, and since Table Tennis is a game which combines rapid decision-making, as well as matching the type of strike and its quality to the characteristic of the returning, this type of integrated training is the best in his opinion.
Research conducted by Vickers on two groups showed that the group that received motor training combined with video analysis of the way in which the game was played and drawing conclusions from the analysis improved achievements more than the group that learnt the technical skill only (Vickers, 2003; Raab et. al., 2005).
In their research, Zhang et. al. (2012) added play practice training to the components of Table Tennis such as the initial serve and strike, as well as Skill-focus instruction (SI). In this case, too, the research findings showed, although other components were measured as well, that training accompanied by guidance and explanations was more effective that training without explanations (Zhang et. al., 2012).
Table tennis is one of the fast ball games branches, and hence, a coach experiences all the elements and nuances of effective training (Sindik, 2013). From the perspective of sport, effective training or an effective game is expressed in the result.
Success depends on the analysis of data about the given object. A Table Tennis player who succeeds in seeing the ball at the right time and the right place is likely to successfully strike back. Timing then is of the utmost significance for the player to transfer motor commands based on information received visually. Additional information obtained visually may also help assess the type of serve and its characteristics. Sergio et. al. (2002) conducted research which showed how the eye-hand coordination is of great significance in Table Tennis. The research findings revealed that competent players followed the ball with their eyes and reached higher achievements than the less competent ones (Sergio et. al., 2002).
Hand-eye coordination is one of the components representing this sport branch directly. Most hand-eye coordination studies have been conducted in laboratory conditions and cannot genuinely testify to what happens in a real Table Tennis game (Williams & Davids, 1998). One of the first field research studies examined the players' performance when the coach gave them instructions to keep their eyes on the ball along its trajectory (Pippol & Felurance, 1998). The results showed that players reacted better both in terms of the quality of their strikes and the speed of reaction to balls which reached the middle line of the body rather than to those which went towards the sides.
The field of Table Tennis among individuals with intellectual disabilities has not been sufficiently researched. In the past, individuals with intellectual disabilities who played professional Table tennis could participate in the Paralympics. In 2012, after 12 years without playing, the Olympic Committee approved the return of athletes with intellectual disabilities to the Paralympics, and decided not to limit their participation to the Special Olympics. Classification tests that players have to take to qualify for the Paralympics are measured via numerous parameters, as is the case with all Paralympics participants. Nevertheless, there are other elements such as anxiety, stress or medical problems which might influence the players' state, especially those with intellectual disabilities (Biesen et. al., 2010; Biesen et. al., 2014).
Research conducted by Biesen (2014) focused on individuals with intellectual disabilities who participate in the Paralympics. The research sought to compare the results of technical performance in a game simulation and those of a real game. The findings showed no significant differences between the simulation and a genuine game in most components (Biesen et. al., 2014). To this day, individuals with intellectual disabilities take much longer to learn in general and motor skills in particular. As a rule, it is harder for individuals with intellectual disabilities to learn motor skills than for individuals without intellectual disabilities, and the same is true for reaction time (Porretta & Moore, 1991; Biesen et. al., 2010).
Because the existing tests for examining the motor skills of people with intellectual disabilities are not adapted to their physical and cognitive abilities, we have been adapted this need by these new skills tests.
study on the skills tests was conducted after writing the skills tests and the validity of 11 specialists.
In order to examine the reliability of each measure comprising the test, Alpha Cronbach coefficients were calculated that demonstrated internal consistency between components of each measure.
Ten people participated in the study with moderate intellectual disabilities and motor disabilities aged 30-32.
Research aim
To find components of the movement in table tennis to create skill tests designed to test these components.
Research question
What components might comprise skills tests for intellectually disabled people in four areas: balance, hand-eye coordination, power regulation and coordination?
The Research procedure
In order to answer this question, three stages were undertaken:
Examining existing research tools in each one of the chosen four skills. This showed that there are a number of valid tests that examine these skills but they are unsuitable for an intellectually disabled population group. In light of participants' severe impairments, it was recognized that they would not be able to undertake these tests and adapted tools would need to be built.
Constructing a test to examine each of the four skills. The skill tests, as can be seen in the methodology chapter that follows, were constructed in such a way that the first two motor actions in each skill were taken from known validated tests. The remainder was chosen according to motor actions linked to these skills, for example in the hand-eye coordination skill test, one of the actions was to throw and catch a ball. The tests were sent to 11 experts in different fields: special education, physical education and table tennis experts for analysis and validation.
Internal consistency testing
Research Results
The results are presented as follows:
The analysis demonstrated a high reliability level across the whole measure (α = 0.896). The above table shows that there was no need to remove any component from the general measure.
The analysis demonstrated a high reliability level across the whole measure (α = 0.829). The above table shows that there was no need to remove any component from the general measure.
The analysis demonstrated a high reliability level across the whole measure (α = 0.803). The above table shows that there was no need to remove any component from the general measure.
The analysis demonstrated a high reliability level across the whole measure (α = 0.815). The table above shows that there was no need to remove any component from the general measure.
Distributions show that balance abilities were generally low. In most components, none of the subjects achieved a high level and in three of them, only a small percentage achieved a high level.
Distributions shows that hand eye coordination abilities were low. The football catching measure was especially high. 70% of participants demonstrated a high level of ability catching a large ball.
Distributions show that power regulation abilities are very low. One can discern that the majority of athletes are at a low level in most components, particularly those connected with the game itself such as serve and the like.
Distributions show that coordination abilities were low. Most athletes demonstrated a low or medium level of ability. Most showed a medium level of simple motor pattern planning skills of 2 steps as seen in the first component.
In summary, distributions of the test results prior to the program show that, in general, subjects' abilities were very low in all four measures.
Conclusion
The study results led to the conclusion that the tests constructed were suitable for intellectually disabled people and valid for the research field and that a test that mixes components from existing tests with movement components from the game itself, provides a greater internal consistency.
A further conclusion that arose from the study stage was that the four chosen skills were indeed part of many skills connected to this branch of sport, but were indeed basics of the game and the most significant skills.
