Childhood is the most sensitive period for the development of fundamental movement skills (FMS). The assessments also help identify strengths and weaknesses in coordination, balance, agility and other important skills.
1. Introduction
Motor skills are fundamental abilities that enable individuals to perform various physical tasks efficiently
[1]. Basic skills like walking, running and jumping and complex activities like sports and fine motor tasks play a crucial role in human development and daily functioning. Developing these skills in childhood is fundamental for competitive sports and lifelong activity, since this contributes to physical, mental and social development as well
[2][3][4][5][6]. These benefits also highlight the importance of measuring and continuously monitoring these skills. An accurate motor skill assessment tool serves as an objective measure to evaluate an individual’s physical abilities, and it is essential for identifying strengths and weaknesses. Measuring motor skills in children is a priority for both physical education and youth sports, since it can help teachers and coaches to support the motor skills development that the individual requires.
Ideally, the pillars of motor skills should be developed before the onset of the rapid growth phase in adolescence, since previous studies have already demonstrated that childhood is the most sensitive period for the development of fundamental movement skills (FMS)
[5][7][8]. Several researchers refer to FMSs as the pillars of motor skills, since they are a set of foundational physical abilities that serve as building blocks for more complex and specialized movements. FMSs are essential for developing complex movements that involve the ability to move confidently and effectively in a wide range of physical activities. There are four main categories of fundamental movement skills: locomotor movement skills, object control movement skills, stability movement skills and fine motor movement skills
[1][8].
Table 1 presents the characteristics of the assessment tools. High standard deviations are seen for both the quantity of test items (SD = 20.44) and the duration of the test (SD = 11.30). Three of the tools (MOT 4–6, MMT and BOT-2) appear to be results-oriented, while the M-ABC-2 and TGMD are more process-oriented. Only the TGMD has 2-level scaling in the evaluation process, i.e., evaluating correct or incorrect execution. The other process-oriented assessment tool uses a scale with three or more levels to evaluate partially accurate execution. During testing, the age-appropriate standardized scores from the result-focused assessment tools are used from raw performance scores. The instrument requirements of tools also differ widely, but all of them need some kind of sports equipment to produce the test. There are culture-specific differences. For example, the TGMD can also be performed with tennis and baseball [9].
Table 1. Characteristics and theoretical frameworks of movement skill assessment tools
The content components of the FMS assessment tools are shown in Table 2. Locomotion movement analysis was measured with running tasks in three assessment tools (BOT-2; TGMD-2; TGMD-3). Additionally, most assessment tools involve skipping to measure locomotion movement skills.
Table 2. Content analysis of FMS assessment tools.
Measuring object control movement skills includes different types of throwing, dribbling, kicks, strikes, and other complex exercises (i.e., throw and catch). As seen in Table 2, most of the assessment tools measure a skill with one or more tasks; however, the KTK did not include any tests to measure object control movement skills. Furthermore, it is mostly dominated by upper-limb tests, but the MOBAK, TGMD and MMT examine lower leg coordination.
Static and dynamic balance can be found in the analyzed tools. Almost half of the tests include one-leg and/or two-leg static balance tasks executed with eyes open or closed. Except for the TGMD, all of the assessment tools include dynamic balance tasks, such as walking forward and backwards, and walking heel-to-toe on a walking line or balance beam. Only the MMT and BOT-2 assess fine motor skills without equipment (Table 2). The test includes mainly tasks involving fingers and hands.
In investigating locomotor movement skills measurement, scholars found that the BOT-2 running test is excellent for testing running ability since they use “shuttle run” tests for running agility
[16]. For detecting deficiencies in technical execution, the TGMD-2 or TGMD-3 are recommended to use
[9]. Both tools help to evaluate running techniques with a unitary criteria system. Those coaches or PE teachers who want to investigate the effectiveness of running with the “moving variably” test of the MOBAK-3 will find it useful, in which the running and lateral running should be alternated for effective performance
[24]. Almost all of the assessment tools include hop tests. Depending on the needs, one can choose between one-leg, two-legs, on-the-spot, and forward hopping. The MMT test is recommended
[14] for testing the coordination of two body halves like the hands and feet. Assessing crossed movements during the hop, the BOT-2 assessment tool would be favorable, including suitable tasks
[16]. The MOT 4–6 and KTK are recommended for the high jump, the MMT for the long jump, and the BOT-2 and TGMD for the long jump from a stationary position. The MOBAK is applicable for assessing forward rolls, and the MOT 4–6 test is important for considering the measurement of rolling around the longitudinal axis
[14].
The throws had a prominent place for object control movement skills. The tasks mainly assess the effectiveness of a target throw, such as a one-handed overarm, or a one-handed underarm throw. The TGMD has a good tool that assesses the quality of the execution of the throw. The two-handed catching skill appears in a variety of different tools. The children were tested with balls, hoops, and bean bags in the different assessment tools. Some tools offer complex tests such as “throw and catch” and “release and catch”; these can be found in the BOT-2 and MOBAK-3. The importance of object control movement skills has been shown in ball games and other sport techniques such as tennis and badminton
[25][26][27].
Stability movement skills are tested with static and dynamic balance tests. Static balance is assessed in only four assessment tools. One-leg balancing, such as the flamingo test can be tested on the floor, on the line or on the beam, with eyes open and closed.
Overall, the analysis revealed that to assess locomotor movement skills, the BOT-2 has an excellent test for running ability, but for detecting technical difficulties, the TGMD is recommended. To test hopping, the MMT has the best tests. Object control movement skills are measured with throws, dribbles and catches. Most of the tools assessed these skills, but it turned out that the TGMD has the most tests for it. Stability movement skills are tested with static and dynamic balance tests. When dynamic balance is more used, the MOT 4–6, KTK and BOT-2 have the most tools available. However, the MMT is an excellent test for static balance. Fine motor movement skills are easy to assess with the MMT and MOT 4–6, since they have low equipment requirements. The BOT-2 is the best tool for measuring; however, it has high equipment requirements.
