BACKGROUND: Band joint flossing is where a compression band or thick, elastic band is tightly wrapped around part of a joint. This technique has been shown to improve range of motion of that joint, reduce pain during and after exercise, and increase injury prevention by increasing blood and nutrient flow back to that joint once the compression is released. However, most research on band joint flossing is on range of motion and jumping movements only, despite exercisers and athletes commonly using the band joint flossing technique on before performing squat exercises. Therefore, the purpose of this study is to analyze the effects of band joint flossing on barbell squat and isometric squat performance. METHODS: College-aged females (65.7±2.1 in, 71.2±13.2 kg, 1-RM back squat 72.5±13.2 kg) with previous squat experience were recruited to participate in this study. In a crossover, counterbalanced design, participants completed two trials: 1) band joint flossing (BJF) of both ankles, and 2) control (CON) with no flossing. For BJF, a VooDoo floss band was tightly wrapped around both ankles and participants completed 10-20 repetitions of ankle flexion and extension and 10-20 body weight squats. During both trials, participants completed an isometric squat by standing on force platforms with a smith machine locked in place at a knee angle of 80-100 degrees flexion and maximally pushing. Next, participants completed two back squat repetitions at 75% 1-RM as explosively as possible and velocity was recorded through a linear position transducer. Each trial was separated by a minimum of 48 hours. RESULTS: There was no significant difference between BJF and CON for barbell velocity (p=0.17) during the back squat. Additionally, there was no significant difference in peak force (p=0.72) or net force (p=0.34) during the isometric squat between BJF or CON. CONCLUSION: The results of this study suggests that BJF of the ankles does not improve squat performance with either the back squat or an isometric squat.
