As therapists we are used to have clinical evidence of health improvement after myofascial release therapy. Nevertheless, the scientific evidence of the application of the myofascial release therapy is scarce [1-6]. Since is complicated to objectify the effects of the therapy and there are different ways to apply it. Nowadays, there are also a numerous ways with different tools to self-release the myofascia after physical exercise that have not been proven enough to be effective. Therefore, in order to know more about the effectiveness of this applications and using our experience with the Tesiomyography to evaluate the mechanical characteristics of the muscles through a transversal electrical stimulus and all that is known about the physiological characteristics of the fascia.

The purpose of this study was to compare the acute effects of the use of the Roller Foam and Crossed Hands Technique (Myofascial Therapy) on the mechanical characteristics of biceps femoris (BF) and semitendinosus (ST) muscles of the dominant leg son after a Romanian dead lift exercise. Thirty-four (n=34) students (age: 24.52±3.12 years old) students of Physical Education of the University of Las Palmas de Gran Canaria were evaluated. They were divided into three groups: Roller Foam Group (RG, n=10); Crossed Hands Technique Group (CHG, n=15) and Control Group (CG, n=9). The Tensiomyography (TMG) is used to evaluate the mechanical characteristics of the biceps femoris and semi-tendinosus muscles. Specifically, the Radial Displacement of the muscles’ bellies (Dm) and Contraction Time (Tc) were measured. The measures were taken: in basal conditions; after a 5 min of continuous run (8 km/h) warming up; after a romanian dead lift with growing load of the 1RM: (50%/15 reps, 60%/10reps, 70%/8reps, 80%/6reps, 90%/3reps), with 2min rest between each load set; five and ten minutes after the exercise. The myofascial release applications were just after the first five minutes of rest (Figure 1).

Statistically significant differences (p≤0.05) were found for Dm in the ST of the CHG. Those differences were kept during the whole rest time. This recovery also was registered in the CG for the first 5 min rest (p≤0.05), but not in the last 5 min rest. And RG did not experienced any significant difference. On the other hand, none of the groups got significant changes in BF. However, for TC only the GM could come back to the basal values during the recovering process for both muscles, both after 5 min and after 10 min (Figure 2).

The results got in the CHG agree well with Haas et al. [7,8] and Crawford et al. [10] in their work on rabbit’s musculature after an eccentric exercise, causing greater reduction in neutrophil and macrophage infiltration of the exercised muscle, increasing recovery of mechanical properties and showed histological evidence. On the other hand, individual differences and self-application of the Roller Foam may have influenced the results, as Beardsley & Skarabot [1] and Cheatham et al. [2] suggest in their respective revisions. With these results, we can conclude that in our study the muscular recovery is better after the application of the crossed hands technique.
