NCT07565168
Comparison of Training Intensity Distribution Models in Recreational Distance Runners
This study aims to compare the effects of three different training intensity distribution (TID) models-polarized, threshold, and pyramidal-on physiological and performance adaptations in recreational distance runners. Twenty-four participants will be assigned to one of the three training interventions and will complete an 8-week structured running program based on the respective TID approach. The primary objective is to determine whether different TID models elicit distinct changes in key physiological markers and endurance performance. The study seeks to answer whether a specific intensity distribution strategy provides superior adaptations in recreational runners when training is prescribed over a controlled intervention period.

Effects of Polarized and Threshold Intensity Distribution Models on Race Time and Body Composition in Recreational Runners Aged 20-45 Years.
This study aims to compare the effects of two intensity distribution training (TID) models-polarized and threshold-on 5-km race time and body composition in recreational runners aged 20 to 45 years. Participants will be randomly assigned to one of two groups and will complete a 12-week structured training program. The primary outcome will be 5-km race time, while secondary outcomes will include changes in body composition. Assessments will be conducted before and after the intervention period.
