Associations between Weight Status and Situational Motivation toward Fitness Testing in Physical Education: The Mediator Role of Physical Fitness.

Background: This article examines the differences in situational motivation toward fitness testing in physical education classes between non-overweight and overweight students, as well as the mediator effect of objective and perceived physical fitness on the relationship between weight status and motivation toward fitness testing.

Methods: A total of 534 adolescents (298 boys, 55.80%) participated in the study. Perceived physical fitness and situational motivation toward fitness testing were measured through questionnaires, whereas weight status and physical fitness were objectively measured.

Results: Overweight students had lower intrinsic motivation ( < 0.001), and higher external regulation ( < 0.01) and amotivation ( < 0.05) during fitness testing in a physical education class than their non-overweight peers. The influence of being overweight on motivation regulations toward fitness testing was mediated by objective physical fitness level for intrinsic motivation ( = -0.140), external regulation ( = 0.104) and amotivation ( = 0.146). Perceived physical fitness was also used as a second mediator between weight status and intrinsic motivation ( = -0.117).

Conclusions: Strategies to improve objective and perceived physical fitness in overweight students are necessary to increase self-determined motivation during fitness testing in physical education lesson.
