概括
倾斜跳跃显著改善了落地跳跃起飞速度和肌肉激活. 这种训练方法增强了运动的力量,应该被寻求爆炸性表现的运动员的教练考虑.
科学领域:
- 生物力学 生物力学
- 运动科学 运动科学 运动科学
- 运动生理学 运动生理学
背景情况:
- 运动员的表现很大程度上取决于力量,即快速产生力量的能力.
- 脚 flexor 肌肉对于在爆炸性运动中产生动力至关重要.
- 了解训练对足部 flexors的影响是提高运动能力的关键.
研究的目的:
- 为了研究特定的脚部曲器训练如何影响跳 (DJ) 生物力学.
- 分析不同训练干预后肌肉激活和力量的变化.
- 为了比较倾斜跳跃,平面跳跃和电刺激对跳跃性能的影响.
主要方法:
- 30名男性参与者被分为倾斜跳跃 (IH),飞机跳跃 (PH) 和电刺激 (EMS) 组.
- 所有小组每周训练4次,持续4周,每次10跳10套.
- 评估包括下降跳跃的动力学和电动图学 (EMG) 分析以及异动力学脚下 flexor 力量测量.
主要成果:
- 倾斜跳跃 (IH) 在推进过程中显著改善了下降跳跃起飞速度 (Vto) 和介质胃口 (MGas) 活动.
- 所有组都显示出异常脚部曲器扭矩增加.
- 此外,IH组在同心脚部 flexor扭矩方面也有所改善.
结论:
- 倾斜跳跃是有效的增强下降跳跃V到,可能是由于增加MGas激活.
- 协同激活指数保持稳定,表明有效的力量生产.
- 教练可以整合倾斜跳跃来发展动力;飞机跳跃和电刺激可能有助于整体力量.

01:10Ankle Joint
1.6K
The ankle is formed by the talocrural joint (crural = leg). It consists of the articulations between the talus bone of the foot and the distal ends of the tibia and fibula of the leg. The superior aspect of the talus bone is square-shaped and has three areas of articulation. The top of the talus articulates with the inferior tibia. This is the portion of the ankle joint that carries the body weight between the leg and foot. The sides of the talus are firmly held in position by the articulations...

01:28Muscles of the Leg that Move the Foot and Toes
1.6K
The human leg comprises an intricate system of muscles that facilitate the movement of feet and toes. Within this system, the muscles are categorized into the anterior, lateral, and posterior compartments, each with a unique set of muscles carrying out specific functions.
Anterior Compartment
The anterior compartment includes muscles that contribute to the dorsiflexion of the foot. This compartment houses the tibialis anterior, extensor hallucis longus, and extensor digitorum longus muscles....
