Effects of Two Endurance Training Programs on 5-km Running Performance in Recreational Runners

Официальное название

Effects of Lactate Threshold Training and Pyramidal-to-Polarized Endurance Training on 5-km Running Performance, Physiological Capacity, and Post-exercise Neural Responses in Recreational Runners: A Randomized Controlled Trial

Обзор

This study will examine the effects of two 8-week endurance training programs on 5-km running performance in recreational runners. Participants will be randomly assigned to a lactate threshold training group, a pyramidal-to-polarized endurance training group, or a control group that maintains usual physical activity without receiving the study training program. Before and after the intervention, participants will complete assessments of 5-km running performance, aerobic fitness, lactate threshold, running economy, blood lactate responses, and brain activity recorded before and after maximal exercise. The study will compare changes among the three groups and examine whether physiological and post-exercise neural responses are associated with improvements in running performance. The main purpose is to determine whether the two training programs produce different improvements in 5-km running performance and to better understand the physiological and neural adaptations associated with endurance training in recreational runners.

Вмешательства

• Поведенческое Lactate Threshold Training
  Participants will complete an 8-week individualized endurance training program prescribed primarily around the lactate threshold. Training intensity will be determined from baseline physiological testing. The program will specify the frequency, duration, and intensity of each training session and will be adjusted according to the study protocol.
• Поведенческое Pyramidal-to-Polarized Endurance Training
  Participants will complete an 8-week individualized endurance training program in which the training-intensity distribution progresses from a pyramidal pattern during the initial phase to a polarized pattern during the later phase. Training intensity will be prescribed using individually determined physiological thresholds obtained from baseline testing. The program will include low-, moderate-, and high-intensity running sessions, with the relative distribution of training time across intensity
