Abstract

Accommodating resistance is a common training method involved in strength and conditioning that involves the usage of bands or chains attached to a barbell that changes the total resistance as the user moves through a range of motion (ROM). Accommodating resistance increases both acute strength and power performance and creates greater long-term adaptations than traditional barbell loading, however, the contributors of this phenomenon are unknown. The purpose of this study was to evaluate whether acute stiffness changes in superficial myofascial tissue aided in the strength and power adaptations found in prior accommodating resistance research. It was hypothesized that banded loading would result in greater fascial stiffness when compared to traditional barbell loading in the vastus lateral (VL), biceps femoris (BF), anterior deltoid (AD), and posterior deltoid (PD) muscles. Twenty resistance trained men were recruited for the study. The study contained two conditions, and each subject was randomly assigned to the traditional condition (TRAD), or the banded condition (BAND) which dictated which condition would be conducted first during the data collection in the squat exercise. Subjects increased load in 5% increments until a mean bar velocity of 0.4 m/s was reached. Both conditions were collected on the same day with a 12-minute break between sets. Tissue stiffness was collected using a Myoton Pro device before and after each condition for a total of four collections for the VL, BF, AD, and PD muscle groups. A three-way ANOVA was used to evaluate interactions between time, condition, and muscle. There were no significant three-way or two-way interactions found. There was a significant main effect for muscle (F=92.55, P=< .001). It can be concluded tissue stiffness varies between muscle groups (VL, BF, AD, PD), however, no relationship was found between tissue stiffness changes pre and post banded and traditional loading.
