Novel Fiberglass Resistance Pole Training Implement: Reference Values for Exercise Prescription
Journal Title: Biomedical Journal of Scientific & Technical Research (BJSTR) - Year 2018, Vol 11, Issue 3
Abstract
Background: Functional strength training often employs the use of elastic materials that allow for versatile movement. New materials have been developed to provide more options for functional resistance training. Core Stix™ is a new technology that utilizes fiberglass polymer resistance poles flexed through a range of motion, creating tension. This study quantified the tension of Core Stix™ poles across different pole colors and degrees of flexion. Furthermore, the influence of hand position on tension within each pole was assessed. Methods: A basic Core Stix Fitness System was utilized for research and consisted of a platform with socket inserts and 5 different resistance pole intensities. Each pole intensity was assessed for tension at 10 degree increments, from 0-60º as per the suggested manufacturing limits of use. Additionally, the large foam resistance handle was divided into 4 equal segments (hand positions), and force measures were taken at each position across poles and degrees of flexion. Tension was measured 4 times, and the mean used for analysis. Repeated measures ANOVAs with Tukey post hoc comparisons assessed differences across pole types and hand position. Results: A linear relationship between pole flexion and resistance was observed. A significant difference in loading was shown between each of the pole colors, while hand placement became a significant factor between the top and bottom position. Conclusion: Resistance loading across poles and degrees of flexion is linear and graduated. Resistance can be varied by changing hand position or poles. Practitioners can use these values for more precise exercise programming.Training to improve functional strength requires performing exercises that overload the muscle while also allowing for a variety of functional movements. The use of free weights or machines during exercise often prevents variations in angle, speed, and torso movements that are necessary for functional training. Alternative forms of resistive equipment have been developed using elastic bands or flexible materials, which overcome these limitations. Resistance bands are a popular option for muscular rehabilitation due to their ability to be used in a variety of movement planes and effectively strengthening the muscle. The bands are color-coded, with each color representing different resistance properties, creating a range of loading schemes. The amount of resistance elastic materials provide is dependent on the stretch deformation characteristics. Generally, the amount of tension provided increases proportionally with the amount of deformation the band undergoes. Studies have been published quantifying the resistance measurements of elastic bands. Hughes et al. [1] determined the resistance properties of 6 progressive levels of Thera-Band™ tubes during shoulder abduction exercise. The study showed a positive, linear relationship between tube length and tension, with significant tension differences between each of the different colored tubes. Uchida et al. [2] published data showing tension for Thera-Band™ elastic bands at strain values between 25% and 250% of resting length. By quantifying the resistance of these bands, these data provided useful information to practitioners that allows them to appropriately prescribe loads for training.
