简要总结
Thoracic injuries, in high level competitive Brazilian jiu jitsu (BJJ) athletes occupied a significant percentage of all musculoskeletal injuries in this population. Important factors for reducing injury rates are suggested to be spine and thoracic flexibility, which assist athletes in performing offensive/defensive techniques. The diaphragm, as one of the main thoracic and breathing muscles, appears to affect spinal flexibility and chest expansion. Thus, this study's objective was to investigate the immediate effects of a myofascial release technique of the diaphragm on chest mobility (expansion) and spinal range of movement (ROM) in BJJ athletes.
详细描述
In order to be assesed the immediate effects of a myofascial release technique on diaphragm, competitive BJJ athletes were subjected to a diaphragmatic release technique and to a sham breathing technique, in random order, across a two-week interval with outcome measures involving thoracic flexion/extension ROM, chest expansion, finger-to-floor (FTF) test and Modified-modified Schober's test (MMST).

研究组 & 干预措施
Myofascial release intervention arm
This myofascial technique was a manual hterapy treatment technique performed in sitting. With this technique, the athlete slightly bends his/her torso in order to relax the abdominal wall and breathes calmly and deeply . The therapist is behind the athlete holding his/her lower ribs, and during exhalation the therapist directs his hands caudally. This steady but gentle 'traction' is maintained throughout the breathing cycles for 4-5 minutes.
干预措施: Manual therapy intervention (Chaitow's myofascial diaphragm release) (Other)
Sham intervention arm
With this technique (also performed in sitting), the therapist stood behind the athlete touching the outside of the person's lower ribs without folding his or her fingers or applying any pressure. The athlete is verbally instructed, after fully exhaling the air in their lungs to take deep breaths opening his/her ribs as much as he/she can whistle the therapist's hands follow the movement (without applying any manual pressure or traction). The procedure here also lasted for 4-5 minutes.
干预措施: Sham Comparison (Other)
结局指标
主要结局
Chest expansion measurement as assesed by tape measure
时间窗: Before and immediately after the intervention
Chest expansion was measured in centimeters with a tape measure at two thoracic levels. For the upper chest, the anatomical landmarks used were T5 spinous process, the midline of the clavicle and the third intercostal space. For the lower chest, T10 spinous process and the xiphoid process were used.
次要结局
- mobility of the thoracolumbar region as assesed by the Modified-modified Schober's test (MMST)(Before and immediately acfter the intervention)
- goniometry of the thoracic flexion and extension range of movement as assessed by buble inclinometers(Before and immediately after the intervention)
- overall mobility of the posterior kinetic chain as assesed by the Fingertip-to-Floor (FTF) test(Before and immediately after the intervention)
