Cryotherapy, in the form of ice massge is used to reduce inflammation after acute musculoskeletal injury or trauma. The potential negative effects of ice massage on proprioception are unknown, despite equivocal evidence supporting its effectiveness.
The purpose of the study was to test the influence of cooling on weight discrimination ability and hence the performance in footballers.
The study was of same subject experimental design (pretest-posttest design). Thirty male collegiate football players, whose mean age was 21.07 years, participated in the study. The participants were assessed for two functional performance tests, single leg hop test and crossed over hop test and weight discrimination ability before and after ice massage for 5 minutes on hamstrings muscle tendon.
Pre cooling scores of Single Leg Hop Test of the dominant leg in the subjects was 166.65 (± 10.16) cm and post cooling scores of the dominant leg was 167.25 (± 11.77) cm. Pre cooling scores of Crossed Over Hop Test of the dominant leg in the subjects was 174.14 (± 8.60) cm and post cooling scores of the dominant leg was 174.45 (± 9.28) cm. Pre cooling scores of Weight Discrimination Differential Threshold of the dominant leg in the subjects was 1.625 ± 1.179 kg compared with post cooling scores of the dominant leg 1.85 (± 1.91) kg. Pre cooling scores of single leg hop and crossed over hop test of the dominant leg in the subjects compared with post cooling scores of the dominant leg showed no significant differences and it was also noted that the weight discrimination ability (weight discrimination differential threshold) didn't show any significant difference. All the values are reported as mean ± SD.
This study provides additional evidence that proprioceptive acuity in the hamstring muscles (biceps femoris) remains largely unaffected after ice application to the hamstrings tendon (biceps femoris).
以冰敷形式进行的冷冻疗法用于减轻急性肌肉骨骼损伤或创伤后的炎症。尽管有一些模棱两可的证据支持其有效性,但冰敷对本体感觉的潜在负面影响尚不清楚。
本研究旨在测试冷却对重量辨别能力的影响,进而测试其对足球运动员表现的影响。
本研究采用同一受试者实验设计(前测-后测设计)。30名平均年龄为21.07岁的男性大学足球运动员参与了研究。在对腘绳肌肌腱进行5分钟冰敷前后,对参与者进行两项功能表现测试,即单腿跳测试和交叉跳测试以及重量辨别能力测试。
受试者优势腿单腿跳测试的预冷却得分是166.65(±10.16)厘米,优势腿的后冷却得分是167.25(±11.77)厘米。受试者优势腿交叉跳测试的预冷却得分是174.14(±8.60)厘米,优势腿的后冷却得分是174.45(±9.28)厘米。受试者优势腿重量辨别差异阈值的预冷却得分是1.625±1.179千克,而优势腿的后冷却得分是1.85(±1.91)千克。受试者优势腿单腿跳和交叉跳测试的预冷却得分与优势腿的后冷却得分相比无显著差异,并且还注意到重量辨别能力(重量辨别差异阈值)没有显示出任何显著差异。所有数值均以平均值±标准差表示。
本研究提供了额外的证据,表明对腘绳肌腱(股二头肌)进行冰敷后,腘绳肌(股二头肌)的本体感觉敏锐度在很大程度上未受影响。
