Effects of Two Endurance Training Programs on 5-km Running Performance in Recreational Runners
2026年7月30日 更新者：Shuqi Jia
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
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.

実験的：Lactate Threshold Training Group
Participants assigned to this group will complete an 8-week endurance training program primarily prescribed around their individually determined lactate threshold intensity.
Training intensity will be individualized using baseline physiological testing and adjusted according to the study protocol.
Participants will complete the prescribed training sessions throughout the intervention period and will undergo the same pre- and post-intervention assessments as the other study groups.

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.

実験的：Pyramidal-to-Polarized Endurance Training Group
Participants assigned to this group will complete an 8-week periodized 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.
Exercise intensity will be individualized using baseline physiological testing and adjusted according to the study protocol.
Participants will undergo the same pre- and post-intervention assessments as the other study groups.

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 zones adjusted according to the planned periodization.
Training frequency, session duration, and intensity will be standardized according to the study protocol and monitored throughout the intervention.

介入なし：Usual Activity Control Group
Participants assigned to this group will continue their usual physical activity and running habits during the 8-week study period and will not receive either of the structured training programs administered by the research team.
Participants will be asked not to begin any new structured endurance training program during the intervention period and will undergo the same pre- and post-intervention assessments as the training groups.

Change in 5-km Running Performance
時間枠：Baseline and immediately after the 8-week intervention
|
5-km running performance will be assessed using a maximal-effort self-paced 5-km run conducted on a standard 400-m outdoor athletics track.
Completion time will be recorded in seconds.
The primary outcome will be the change in 5-km completion time from baseline to the end of the 8-week intervention.
A lower completion time indicates better running performance.

Change in Maximal Oxygen Uptake
時間枠：Baseline and immediately after the 8-week intervention
|
Maximal oxygen uptake will be assessed during a graded cardiopulmonary exercise test performed to volitional exhaustion.
Oxygen uptake will be measured breath-by-breath and expressed relative to body mass in milliliters per kilogram per minute.
The outcome will be the change in maximal oxygen uptake from baseline to the end of the 8-week intervention.

Change in Lactate Threshold
時間枠：Baseline and immediately after the 8-week intervention
|
Lactate threshold will be determined during an incremental running test using blood lactate measurements and the prespecified threshold-identification method described in the study protocol.
The outcome will be the change in running speed or physiological intensity corresponding to the lactate threshold from baseline to the end of the 8-week intervention.

Oxygen uptake will be measured during the steady-state period and expressed relative to body mass.
The outcome will be the change in oxygen cost of running from baseline to the end of the 8-week intervention.
A lower oxygen cost at the same running speed indicates better running economy.
