T-BOW® Material Resistance

Updated: Sep 18, 2023



Synthetic fiber arch (high density polyethylene), with dimensions 70x50x17 cm., a weight of 3.2 kg, with non-slip natural rubber feet, useful on both sides, whose concave side has a granules to prevent slipping and a very narrow surface on the short sides, and whose convex side (with slightly more accentuated curvature than the typical physiological lumbar), is covered with an Three holes on each long side provide a practical fixation for all types of rubbers and bands. Very manageable and useful in a small space.






More than 40 T-BOW® can be stacked In a practical, stable and hygienic way.








Perfectly balanced and with high elasticity, the T-BOW® resists static loads of more than 350 kg, immediately recovering its functionality, both in the synthetic fiber version (treated with ultraviolet stabilizers to maintain its mechanical properties for many years.) in natural wood.



In 2005, the Swiss inventors and manufacturers of T-BOW® found that by applying increasing forces on the surface of the T-BOW®, it begins to deform significantly from forces greater than 400 kg; and that when such a level of force is not applied, the T-Bow progressively recovers its natural shape and all its possibilities of use remain optimal.

Study of the resistance to high dynamic loads of T-BOW® (July 2008, Barcelona). A team of coaches from EEB Sport Training Barcelona (Dani Pérez-Teixidó, Ivan Chulvi-Medrano and David Ribera-Nebot) carried out several tests for the application of dynamic loads on the T-BOW® and in all cases the elastic capacity of the T-BOW® allowed an immediate recovery of its natural form and all its possibilities of use under optimal conditions. Executor: Dani Pérez-Teixidor (disc pitcher athlete, 42 years old). A) Progressive loads in a rocker position up to 350 kg. Discharged 350 kg with immediate recovery of shape and balancing capacity. B) 300 kg support in a convex position. C) Rolling support with 300 kg. D) Support of 1/2 Squat with 250 kg.




VIDEOS OF THE EXPERIENCE


Progressive loads in a rocking position up to 350 kg (Holdoutline Bar 20 kg + 330 kg in discs)

350 kg discharge with immediate recovery of form and balancing capacity Detail: in the central part of both edges of the T-BOW® the pressure of the bar caused a small sinking with the round-longitudinal shape of the bar and about 45 minutes later it disappeared completely.



300 kg support in a convex position (100 kg of the athlete + 200 kg of the bar plus discs)



Soporte de Balanceo with 300 kg (100 kg of the athlete + 200 kg of the barra más discos) Nótese la técnica de apoyos de pies para colocarse y salir en/de los cantos del T-BOW®, ideada por el atleta Dani Pérez.



Soporte de 1/2 Squat with 250 kg (100 kg of the athlete + 150 kg of the barra más discos) Nótese la técnica de apoyos de pies para colocarse y salir en/de los cantos del T-BOW®, ideada por el atleta Dani Pérez.



Wood T-BOW® resistance · 360 kg Static-Dynamic

September 2023, Barcelona



The renewed version of the original Swiss Wood T-BOW® from 1995 resists static and dynamic loads exceeding 360 kg.


The arch of the Wood T-BOW®, 50 degrees, is perfectly adapted to the typical natural arch of the lumbar lordosis (40-60 degrees), and it was designed based on the physiotherapy by Sandra Bonacina in 1995 at Zurich University, Switzerland.


With a single unbalance axis, perfectly balanced, very low weight, high elasticity and resistant to static-dynamic loads of more than 350 kg, both the wood and plastic versions, the T-BOW® is reactive to the slightest movement, changing its inertia quickly, thus optimizing a Postural and coordinative adjustment with a high level of precision, both in a stable curved-convex step position, as well as in the unstable concave rocker and concave/convex double T-BOW® positions.
