Brief summary
Road running in athletics has grown worldwide in recent years, which has led to an increase in the number of recreational runners. Despite this growth, research addressing this population is scarce, with major limitations and methodological weaknesses. Two of the topics of recent interest in runners are the effects of training intensity distribution (TID) and mental training using mindfulness on running time, body composition and physiological parameters related to performance in endurance sports; the maximal oxygen consumption (VO2max), maximal aerobic speed (MAS) and ventilatory thresholds (VT). The scarce evidence found identifies the TID polarized model as the most effective in sports performance and TID pyramidal model as the most used by elite runners. For mindfulness, it is identified as an emerging program that could contribute to performance in endurance sports.
Detailed description
40 recreational long-distance runners will be randomly assigned into one of the following 4 TID models groups: polarized TID model group with mindfulness program (POL+), polarized TID model group without mindfulness program (POL-), pyramidal TID model group with mindfulness program (PYR+) and pyramidal TID model group without mindfulness program (PYR-). Each group will be composed of 10 subjects. The interventions will have a duration of 12 weeks. All participants will have evaluation of 10 km running time, body composition and physiological parameters (VO2max, MAS and VT's 1 and 2) at week 0 and 13 of the study.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change in 10 km race time | Week 0 and 13 | The time in the 10 km will be taken by two evaluators with independent stopwatches, and the average of them will be taken as the official time. The test will take place in a 1257 m loop, with a positive difference in altitude of 5 m. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Change in ventilatory threshold 1 | Week 0 and 13 | Incremental test to exhaustion on a Woodway© model 4Front treadmill. During the test, ventilatory threshold 1 will be measured by a portable metabolic system COSMED© model K5. Ventilatory threshold 1 will be defined as the first increase in ventilatory equivalent for oxygen (VE/VO2) vs. load, without a simultaneous increase in ventilatory equivalent for carbon dioxide (VE/VCO2) vs. load. |
| Change in ventilatory threshold 2 | Week 0 and 13 | Incremental test to exhaustion on a Woodway© model 4Front treadmill. During the test, ventilatory threshold 2 will be measured by a portable metabolic system COSMED© model K5. Ventilatory threshold 2 will be defined as the second increase in ventilation with a concomitant rapid increase in VE/VO2 and VE/VCO2 and a decrease in the partial pressure of exhaled carbon dioxide (PETCO2). |
| Change in maximal aerobic speed | Week 0 and 13 | Incremental test to exhaustion on a Woodway© model 4Front treadmill. During the test, maximal aerobic speed will be measured by a portable metabolic system COSMED© model K5. The maximal aerobic speed will be determined at the speed corresponding to the VO2max. |
| Change in VO2max | Week 0 and 13 | Incremental test to exhaustion on a Woodway© model 4Front treadmill. During the test, VO2 will be measured breath-by-breath by a portable metabolic system COSMED© model K5. The VO2max will be calculated as the average oxygen consumption of the last 30 seconds measured in the incremental test. |
| Change in body fat | Week 0 and 13 | Body fat (%) will be obtained using a HBF-514C OMRON© body composition analyzer |
| Change in muscle mass | Week 0 and 13 | Muscle mass (%) will be obtained using a HBF-514C OMRON© body composition analyzer |
| Change in body weight | Week 0 and 13 | Body weight (kg) will be obtained using a HBF-514C OMRON© body composition analyzer |
