Brief summary
This study has as main objective to know how the processes of recovery are realized after a race of marathon. For this, the participants of a marathon race are divided into three work groups during the 9 days post-marathon, one with rest in the recovery period, another with continuous race three sessions every 48h and another with three sessions of elliptical every 48h .
Detailed description
The marathon runners suffer a high fatigue, as has been studied by different investigations, the proposal of this study is to know how the recovery processes are produced in runners who have completed a 42km test. To do this, baseline measurements of the runners have been made through stress tests and determinations of biomarkers in blood and urine. Subsequently blood and urine samples were taken the day before the marathon test and blood and urine samples were then taken again on arrival at 24h, 48h, 96h, 144h, and 196h. At the same time, an intervention was carried out in the recovery phase, with the runners in three groups. The first one performed rests during the 9 days after the race, the second performed continuous race monitored every 48h from the end of the race, and the third group performed aerobic work on an elliptical machine under the same conditions as the group of Continuous race

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change in the Blood Physiological parameters | baseline, 0, 24, 48, 96, 144 and 192 hours post-race | Blood test |
| Analysis of tne changes in the Physical activity data | One month before the pre-race, accelerometers were worn during seven days. Accelerometers were also worn during nine days starting from the night before the marathon race | Physical activity measured by wearing accelerometer devices. Physical activity defined as sedentary, light, moderate and vigorous. The aim to wear accelerometers devices is to monitor individuals during recovery time post-marathon race |
| Change in the Urin Physiological parameters | baseline, 0, 48, 96, 144 and 192 hours post-race | Urin test |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Physical Condition | One month before the marathon race day | Maximal oxygen consumption |
| Self-reported questionnaire | One month before the race day | Personal questionnaire asking for social and training habits |
| Heart rate | Through marathon completion, an average of 4 hours | Recording the number of contractions of the heart per minute (bpm) by using a heart rate monitor during all the marathon race |
| Body composition | One month before the marathon race day | Bioimpedance analysis |
| Strength level | pre-marathon race and 0, 48, 96, 144 hours post-marathon race | Squat Jump (cm). Two jumps per person |
| Analysis of the change of body mass index | one month before the marathon race day, 24 hours before the marathon race, 2 hours before the marathon race and 10 minutes after the marathon race | BMI |
