Flossing may report benefits on range of motion. However, it's unknown whether flossing using pneumatic tourniquets may influence performance in bilateral countermovement jumping tests.
To analyze the acute effects induced by a flossing protocol with a pneumatic tourniquet placed at the intermalleolar level on jumping ability in basketball players.
cross-sectional study.
54 basketball players (mean (SD) 17.16 (1.27) years; 22.23 (1.99) kg/m) from a professional club were recruited. After a familiarization phase, a pressurized cuff (continuous pressure at 180 mmHg) was placed at the intermalleolar level for 2 min performing plantar and dorsal flexion movements without load. The Leg Motion test and the Countermovement jump were used to measure ankle dorsiflexion and vertical jump height.
After the intervention, a significant ankle dorsiflexion improvement was observed in the left leg in males (12.48 (5.08) vs. 13.44 (5.23) cm, p < 0.05) and in both ankles in females (right: 9.59 (3.29) vs. 10.74 (3.34) cm, p < 0.05; left: 9.91 (2.77) vs. 10.96 (2.57) cm, p < 0.05). However, the intervention showed no significant difference in bilateral jumping ability in neither group (p > 0.05).
The application of intermalleolar flossing using pneumatic tourniquet in elite basketball players did not interfere in jumping ability, and it may improve ankle range of motion. These findings may help clinicians make decisions in practice.
使用牙线可能会对活动范围有好处。但是，使用气压止血带在踝间区域进行牙线清洁是否会影响篮球运动员双侧反跳测试的表现尚不清楚。
分析在踝间区域放置气压止血带的牙线清洁方案对篮球运动员跳跃能力的急性影响。
横断面研究。
招募了来自一家职业俱乐部的 54 名篮球运动员（平均（标准差）年龄 17.16（1.27）岁；22.23（1.99）kg/m²）。在熟悉阶段后，在踝间区域放置一个加压袖带（持续压力为 180mmHg），进行 2 分钟的足底和背屈运动，不施加负荷。使用 Leg Motion 测试和反跳测试来测量踝关节背屈和垂直跳跃高度。
干预后，男性左踝关节背屈明显改善（12.48（5.08）cm 比 13.44（5.23）cm，p<0.05），女性双侧踝关节背屈均有改善（右侧：9.59（3.29）cm 比 10.74（3.34）cm，p<0.05；左侧：9.91（2.77）cm 比 10.96（2.57）cm，p<0.05）。然而，两组的双侧跳跃能力在干预后均无显著差异（p>0.05）。
在精英篮球运动员中使用气压止血带进行踝间牙线清洁不会干扰跳跃能力，并且可能改善踝关节活动范围。这些发现可能有助于临床医生在实践中做出决策。
