The influence of motor learning methods on motor performance stability: The moderating effect of reinvestment propensity.

Different motor learning methods (explicit or analogy learning) show different effects on motor performance stability, and reinvestment propensity plays an important role in motor performance stability. This study aimed to explore whether reinvestment propensity, that is, movement self-consciousness (MS-C) and conscious motor processing (CMP) as two dimensions, played a moderating role in the relationship between motor learning methods and motor performance stability. A total of 78 participants were randomly assigned to either the explicit or analogy learning group and their reinvestment propensity was measured. We recorded the number of golf putt goals in both the practice phase and the test phases (including a retention test and a stress test). In the moderating analysis, participants' reinvestment propensity was the moderating variable, and the dependent variable was motor performance stability (i.e., the difference between the two test phases). Results showed that motor performance was significantly different between practicing blocks, which indicated that the motor performance of learners was gradually increasing. The significant interaction between learning methods and the test phase on motor performance was detected, suggesting under stress, analogy learning was more likely to maintain the stability of motor performance, while explicit learning impaired the stability of motor performance. The CMP played a significant moderating role in the relationship between motor learning methods and motor performance stability. The result indicated that for learners with low CMP, the motor performance stability of analogy learning was better than explicit learning, while there was no significant difference in the stability of motor performance between the two learning methods for learners with high reinvestment propensity. No significant evidence was found that MS-C played a moderating role in the relationship between motor learning methods and motor performance stability. These findings expand the theoretical framework of motor skill learning and provide theoretical support for motor performance stability.
