Abstract

Resistance Characteristics of the TRX™ Suspension Training System at Different Angles and Distances from the Hanging Point

The purpose of this research was to descriptively evaluate the percentages of body mass resistance experienced by users of the TRX™ suspension training system (STS) at different angles and distances from the hanging point. This information will be used to develop prediction equations and better prescribe resistance using this mode of exercise. Forty female and male college students were used as subjects. The TRX™ STS was connected to a dynamometer, suspended from a power rack. From the standing position, subjects leaned back and held the TRX™ handles at arm’s length at 30°, 45º, 60º, and 75º with their feet directly under the hanging point. Dynamometer readings were taken at each degree increment. Each angular measurement was repeated at 30.5 cm increments moving away from the hanging point. Prediction equations were calculated for each angle based on measurements taken at the hanging point. As the angle from standing increased, the amount of resistance encountered increased. On average, subjects experienced 37.44 ± 1.45% of their body mass at 30º, 52.88 ± 0.59% at 45º, 68.08 ± 1.95% at 60º, and 79.38 ± 2.14% at 75º from vertical. The effect of 30.5 cm increments moving away from the hanging point on resistance was somewhat variable. In conclusion, a decreased angle resulted in an increased body mass resistance during use. Increment changes produced progressive, linear variations in resistance. Prediction equations can allow more accurate predictions of resistance at the angles measured in this investigation..
