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 .
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

Running at 95-105% aerobic Threshold on elliptical machine 48h, 96h, 144h after the race. Control heart devices
Change in the Blood Physiological parameters
Blood test
Time frame: baseline, 0, 24, 48, 96, 144 and 192 hours post-race
Analysis of tne changes in the Physical activity data
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
Time frame: 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
Change in the Urin Physiological parameters
Urin test
Time frame: baseline, 0, 48, 96, 144 and 192 hours post-race
Self-reported questionnaire
Personal questionnaire asking for social and training habits
Time frame: One month before the race day
Strength level
Squat Jump (cm). Two jumps per person
Time frame: pre-marathon race and 0, 48, 96, 144 hours post-marathon race
Analysis of the change of body mass index
BMI
Time frame: 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
Physical Condition
Maximal oxygen consumption
Time frame: One month before the marathon race day

Body composition
Bioimpedance analysis
Time frame: One month before the marathon race day
Heart rate
Recording the number of contractions of the heart per minute (bpm) by using a heart rate monitor during all the marathon race
Time frame: Through marathon completion, an average of 4 hours
