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.

During prolonged endurance exercise, certain physiological variables deteriorate depending on the duration of the exercise. Physiological resilience has therefore been defined as the ability to resist these changes and appears to be an important performance factor in endurance sports. For example, most studies in this field have investigated changes in cycling power output associated with the first ventilatory threshold (VT1), a marker of an individual's endurance capacity, after prolonged endurance exercise. To date, only two studies have examined the effects of training on resilience. The first compared the effectiveness of two training programs, one with low-intensity sessions and the other with high-intensity sessions, with no difference between the conditions. The second study showed that incorporating strength training into a running training program was more effective at improving resilience than running alone. However, the influence of training session duration on resilience remains unknown. Only one observational study has shown that in a group of runners of similar ability, those who were used to doing long sessions had better resilience than those who only did short sessions.

Lots of people, including athletes and people who like to exercise regularly, enjoy marijuana. Some people believe marijuana might improve their ability to exercise. There are no recent, up-to-date scientific studies to suggest that this belief is right or wrong. The goal of this study is to determine the influence of marijuana on exercise performance.
