Training intensity distribution on running time in amateur endurance runners: a scoping review

Problem: Intensity in endurance training is important for improving race time; its optimal handling amateur runners has not been extensively studied. The polarized intensity distribution (TID) model emerges as a possibility to reduce however, effect of this remains be demonstrated compared other TID models. Objective: objective study explore the current state evidence gaps, according on time Method: A scoping review without date restrictions was carried out PubMed, EBSCO, SciELO, LILACS, and Google Scholar. Randomized controlled studies, quasi-experimental case which comprise time, were include. Results: Five studies evaluated running using models runners; four them did show differences between groups times two, five, ten km. Only one showed significant difference at 21 Conclusions: with models, except report higher by km threshold TID: 1 hour. 20 min. 22 seconds 26 34s, respectively. scarce found, heterogeneity distances zones same TID, duration interventions, monitoring loads, are main limitations found studies. could contribute adherence, lower perception effort, injury prevention.
