This is a control-case study. It has been designed to determine if there is a relationship between the cross sectional (thickness), through RUSI ultrasound, of the abdominal muscles, lumbar and hip muscles with the results of the functional tests, to determine its relevance in patients with low back pain and / or ciatalgia and lumbar disc herniation in non-professional athletes. The secondary objectives of the study will be to know if there is a relationship between the results of ultrasound measurements and functional tests with the result of the disability questionnaires, the amount of pain and its location, as well as determine the relevance, depending on the results of ultrasound measurements and test of the presence or not of a lumbar disc herniation.

Test Position: Standing barefoot on a grid with an anterior, posteromedial and posterolateral line at a 45° angle away from the projected anterior line.
For the anterior test: most distal aspect of the toes aligned with the tape, centre of heel in line with the tape. For the posterior tests: most posterior aspect of the heel aligned with the tape and the second toe on the tape.
Test: Stand barefoot with the foot aligned to the tape and hands to the side. With the other leg, reach out as far as possible in the tested direction with the most distal part of the foot. 4 practice trials are mandatory in each direction, test each direction 3 times.
Measurement: Measure the reach distance in each direction and register the maximal reach distance in cm. The distances will be compared to each other and to the respective functional leg length. The best result is the longest distance
| 10 minutes |
| Functional test. Side bridging test | Test Position: Athlete is side-lying on an exercise mat. Both feet are in contact with the floor, the fore-arm perpendicular to the athlete's body. The other hand is holding the shoulder. Test: Athlete attains a side-bridge position, keeping both feet and one fore-arm in contact with the floor. Tester helps the athlete attain a neutral position of the lumbar spine and positions the head in the same line. Two practice trials are allowed. Test both sides, with at least 10 minutes of rest between sides. In some cases, only 1 side needs to be tested. Measurement: Measure the time the athlete is able to keep this neutral position. Correct the athlete's position if necessary, if he's unable to maintain the position for 2 consecutive seconds, stop the test. The best result is the longest time | 10 minutes |
| Functional test. Modified biering-sørensen | Test Position: Prone position, the ASIS just over the edge of the treatment table. Arms crossed over shoulders.Neutral position of spine. Test: Instruct the athlete to maintain the neutral position as long as possible (surfaced at 4min).Test fails when the athlete is unable to maintain this position for more than 2 executive seconds (2 corrections allowed). Fail towards hyperextension/flexion. A horizontal cord at spina scapula level can be used to identify deficits. Measurement: Timing is recorded and marked in seconds. The best result is the longest time | 10 minutes |
| Functional test. Prone bridging test | Test Position: Prone-lying with parallel forearms, thumbs up and straight legs. Test: Attain a bridging position with vertical upper arms and with the shoulder, greater trochanter and lateral malleolus in line. The head keeps in contact with an wall in front of a pacient to avoid excessive head movement. Two practice trials are allowed. Measurement: Measure the time the athlete is able to keep this frequency and the correct position. Correct the athlete's position if necessary, if he's unable to maintain the position or the frequency, stop the test. The best result is the longest time | 10 minutes |
| VAS escale | The most simple VAS is a straight horizontal line of fixed length, usually 100 mm. The ends are defined as the extreme limits of the parameter to be measured (symptom,pain,health) orientated from the left (worst) to the right (best). Scoring and Interpretation: Using a ruler, the score is determined by mea-suring the distance (mm) on the 10-cm line between the "no pain" anchor and the patient's mark, providing a range of scores from 0-100. A higher score indicates greater pain intensity. | 1 minute |
| Roland-Morris Disability Questionnaire | It is used to determine the degree of disability. The extreme values oscillate between 0 (absence of disability due to low back pain) and 24 (maximum possible disability). | 5 minutes |
| The Owestry Disability Index | Interpretation: Add the points of each section and place them in the following formula, in order to calculate your level of disability. total points / 50 X 100 =% disability (also known as: 'total points' divided by' 50 ', multiplied by' 100 = percentage of disability) ODI score: 0% to 20% (minimum disability) 21% to 40% (moderate disability) 41% to 60% (severe disability) 61% to 80% (paralyzed) 81% -100%: These patients may be bedridden or may be exaggerating symptoms. A careful evaluation is recommended. | 5 minutes |
| Global Questionnaire on Physical Activity (GPAQ) | The Global Physical Activity Questionnaire was developed by WHO for physical activity surveillance in countries. It collects information on physical activity participation in three settings (or domains) as well as sedentary behaviour, comprising 16 questions (P1-P16). The domains are:
