Relationship Between BMI, Physical Fitness and Motor Skills in Children With Down's Syndrome

Primary outcomes

1. Time up and go (TUG)

   Time frame: 2 months

   The participant will sit in a chair keeping the back straight in contact with the backrest, the feet resting on the floor and the hands on the thighs. At the "go" signal, the subject gets up from the chair, moves as fast as he can to the line fifteen black that is located 3 m from the front legs of the chair, turns and returns to the sitting position traveling a total of 6 m (3 out and 3 back). The timer starts when the subject starts to move and stops when the back touches the back when sitting down.

2. The Deep Trunk Flexibility test (DTF)

   Time frame: 2 months

   The initial position of the subjects was standing with their legs separated at the width of the waist. The subjects flexed their trunk and their knees and put their arms downwards and behind their legs to slide the cursor of the millimeter bar with their fingertips of both hands. A measurement bench (10 × 10 × 55 cm, height, width and length, respectively) was used for the evaluation. Two tries were done, and the best mark was chosen, following the indications of Valdivia et al. with children and adolescents

3. The Hand Grip test (HG).

   Time frame: 2 months

   The subject is placed in a standing position with the dynamometer in his dominant hand. The dynamometer grip is adjusted to the size of the hand to have the second phalanx of the index finger approximately at a right angle. Arms slightly separated from the body. It is not allowed to lean the trunk to any side or bend the elbows. The subject squeezes the dynamometer firmly and gradually, rapidly increasing to maximum force muscles, especially of the finger flexors. The participants were asked to push as hard as possible after the command 'and go'. There were two tries with each hand, establishing 10 s of rest between them

4. Timed Stand Test (TST).

   Time frame: 2 months

   The subject must sit on the chair so that his knees form an angle of 90º. To do this, it will be necessary to adjust the height of the chair for each participant. The subject sits in the chair, which will be leaning against a wall, and is asked to perform ten squats as quickly as possible without using the arms to propel himself. The arms should remain crossed in front of the chest and straighten the knees with each repetition. The timer starts when the movement is started and stops when the subject returns to a sitting position after the tenth squat. Rubber treads may be used to facilitate foot placement for the subject

5. The 30-s Sit-Up (SUP).

   Time frame: 2 months

   The subject must be lying in a supine position with the legs resting on the floor.

   The maximum number of push-ups should be performed for 30 seconds. The correct execution (what is considered a correct complete repetition) is established when the participant raises the scapulae from the ground, keeping the arms stretched out in front and resting them again. As a reference, it was indicated that the subjects touch the patella (put the evaluator's arm in that area to avoid confusion), which in this position forces the scapular area to come off the ground. It is recommended that the investigator hold the participant's legs to prevent any movement of her legs or feet

6. The 6-Min Walk Test (6MWT)

   Time frame: 2 months

   : Regarding the use of the clock, follow the manufacturer's instructions for its correct operation. The participant must try to cover the maximum distance possible in 6 minutes. Running is prohibited, so the subject can only walk fast. It is necessary that the research staff constantly motivate the participants

7. BMI (BMI = kg/m2)

   Time frame: 2 months

   To calculate the BMI, the weight (kg) is divided by the height (m2) difference is greater than 1cm/1kg, a third measurement will be taken. Subsequently, the average is made with the two closest measurements.

8. Waist Circumference

   Time frame: 2 months

   The subject will be standing, with the abdomen relaxed and the arms relaxed parallel to the trunk. The measurement should not be done on clothing, so the shirt should be removed or pulled up without you having to hold it. From this position, the examiner will encircle the subject's waist with the tape measure. The measurement will be made at the narrowest level, between the edge of the lower costal (10th rib) and the iliac crest, at the end of a normal expiration and without the tape pressing on the skin and with the participant's arms at their sides. If there is no obvious minimum waist, the measurement will be taken at the midpoint between the lower costal edge (10th rib) and the iliac crest.

9. ROM

   Time frame: 2 months

   The subject will be placed in a standing position with the legs separated at the width of the hips. The feet will be in line with the edge of the instrument, so that the heels are placed on the line at the 0 level of the scale, and they will not be able to move during the test. At the signal, the person must flex the trunk downwards and backwards, pushing the cursor of the millimeter bar with the middle fingers of both hands (which have passed between the legs) until they advance as far as possible. It is allowed to flex the knees

10. Run
