We investigated whether tropical climate and an external load would influence mental chronometry and whether imagery ability would act as a modera- tor. The Movement Imagery Questionnaire Revised was used to determine good and poor imagers. Participants had to walk and imagine walking toward three tar- gets with and without a 10-kg weight in an airconditioned setting (AC) or tropical climate (TC). Movement times were recorded with a stopwatch. The isochrony index was used to evaluate motor imagery quality. The results revealed that poor imagers had slower times in motor imagery that in actual walking condition and had a lower isochrony index in the AC than in the TC condition at 10-m and 15-m. Regardless of the climate condition, good imagers had a lower isochrony index in the unloaded than in the loaded condition and had a significantly lower iso- chrony index than poor imagers in all conditions. Tropical climate and poor indivi- dual imagery ability can negatively influence mental chronometry.
