Introduction. Basketball is a predominantly anaerobic exercise that exposes to high intensity
actions (jumps, speed control, accelerations and decelerations, and changes of direction). A
lack of flexibility can affect the appearance of muscle injuries. Foam roller is a myofascial
self-release technique using a foam roller. The suction cups are an instrumental technique
where the negative pressure produces an increase in the blood flow of the tissues.
Goals. To evaluate the effectiveness of a physiotherapy intervention through suction cups and
foam roller in amateur basketball players.
Study design. Randomized, single-blind clinical study with a follow-up period. Methodology.
The 20 basketball players that are expected to be recruited will be randomly assigned to the
two study groups: experimental (suction cups and Foam roller) and control (Foam roller). The
intervention will last 4 weeks, with 2 weekly sessions. The study variable will be: hamstring
flexibility (measured with finger-ground, Well and Shober tests). The analysis of normality
will be carried out with the Shapiro-Wilk test. In case of homogeneity of the groups, we will
use parametric tests: t-student test of repeated measures (difference between evaluations)
and ANOVA of repeated means (intra and intersubject effect).
Expected results. An intervention using suction cups and foam roller is effective in
improving the flexibility of the hamstring muscles in basketball players.

| Primary | Change from baseline elongation capacity of the hamstring musculature after treatment and at month | The assessment of the elongation capacity of the hamstring musculature will be carried out by applying the Wells drawer or test. The subject will sit on the floor in front of the drawer, with the feet together and the plants resting on the front of the drawer, and the knees extended. Next, the athlete must tilt the trunk forward and extend the arms, sliding with outstretched hands until reaching the maximum stretch that allows its trunk flexion. The result that will be recorded corresponds to the point you can touch with your fingers. The unit of measurement for this test is the centimeter (the longer the length, the greater the hamstring elongation capacity). | Screening visit, within the first seven days after treatment and after one month follow-up visit | |
| Secondary | Change from baseline ischithiobial extensibility after treatment and at month | The assessment of the ischithiobial extensibility will be made by applying the finger-floor test. The subject will have to reach the greatest possible distance from the standing position with the knees in extension, by bringing the hands (by flexing the spine) towards the ground. The evaluator will measure the distance between the tip of the third finger and the floor, with the unit of measure being the centimeter (a longer length will indicate greater hamstring extensibility). | Screening visit, within the first seven days after treatment and after one month follow-up visit | |
| Secondary | Change from baseline flexibility after treatment and at month | The assessment of flexibility will be measured using the Schober test. The physiotherapist will stand behind the athlete, while the subject is standing with legs extended. The evaluator will mark a line that will connect both posterior superior iliac spines, at the level of the spinous process of the fifth lumbar vertebra. Later a second mark will be made 10 centimeters away in the cranial direction to the first. Next, the subject will be asked to perform maximum flexion of the spine keeping the knees extended. When the subject is in that position of maximum column flexion, a measurement of the distance between the two marks will be made, comparing this result with the initial distance of 10 centimeters. The centimeter is the unit of measurement and a higher score indicates greater muscle flexibility. | Screening visit, within the first seven days after treatment and after one month follow-up visit |
