Revisiting general motor ability, this study proposes a modern, unidimensional model of motor capacity influenced by biology and environment across the lifespan. This framework supports a new Lifespan Motor Ability Scale for comprehensive motor assessment.
Area of Science:
- Motor development
- Human kinetics
- Developmental psychology
Background:
- Specific motor abilities are popular but lack consensus.
- Existing motor assessment tools often yield a single composite score.
- Statistical analyses suggest a global motor ability may exist.
Purpose of the Study:
- Revisit the concept of general motor ability.
- Propose a contemporary model of general motor ability.
- Discuss implications for theory, practice, assessment, and research.
Main Methods:
- Review of current theories and assessment tools.
- Analysis of statistical procedures (factor analyses, cluster analyses, Item Response Theory).
- Development of a hypothesis for a unidimensional general motor ability model.
Main Results:
- Statistical evidence supports a more global motor ability.
- A contemporary model of general motor ability as a unidimensional, emergent, and fluid construct is proposed.
- The Lifespan Motor Ability Scale is introduced.
Conclusions:
- General motor ability is a viable construct.
- The proposed model integrates biological and environmental influences across the lifespan.
- The Lifespan Motor Ability Scale can identify relevant motor assessment tasks for all life stages.

What is a Hypothesis?
Types of Hypothesis Testing
When the null and alternative hypotheses are stated, it is observed that the null hypothesis is a neutral statement against which the alternative hypothesis is tested. The alternative hypothesis is a claim that instead has a certain direction. If the null hypothesis claims that p = 0.5, the alternative hypothesis would be an opposing statement to this and can be put either p > 0.5, p < 0.5, or p...
