概括
间隔投程序逐渐增加肘部扭矩到全力棒球投中看到的水平. 虽然投篮和投篮动力学不同,但它们的一般模式是相似的,有助于康复.
科学领域:
- 运动医学 运动医学
- 生物力学 生物力学
- 康复科学 康复科学 康复科学
背景情况:
- 间隔投计划对于恢复投伤害至关重要,特别是侧带伤害.
- 康复包括逐步增加投篮距离,重复和强度,从平地投篮开始,逐步发展到棒球运动员的土投篮.
- 主要目标是恢复手臂的力量和能力,同时强调适当的投机制.
研究的目的:
- 为了评估间隔投是否逐渐增加关节动力学,特别是肘部的扭矩,以匹配全力棒球投的扭矩.
- 为了比较间隔投的动力学与在棒球投中观察到的动力学.
主要方法:
- 根据PRISMA指导方针进行了系统审查,搜索主要数据库对平地投和部分努力投的生物力学研究.
- 包括专注于平地投球或棒球中部分努力投球的生物力学研究.
- 使用AXIS工具评估研究质量.
主要成果:
- 13项研究 (10项中等质量,3项高质量) 符合纳入标准.
- 在部分努力投篮时,肘部的扭矩比在全力投篮时要低;大多数平地投篮都不超过全力投篮扭矩.
- 增加的投距离通常会提高肘部瓦鲁斯扭矩,但特定距离与全力投扭矩相匹配或超过是不一致的. 像肩膀旋转和球速度这样的动力学模式随着投距离和投球力度的增加而增加.
结论:
- 间隔投程序有效地增加了肘部扭矩,达到与全力棒球投相当的水平.
- 虽然间隔投和投之间存在动力学差异,但整体模式显示出相似之处.

Motion of a Projectile
844
Projectile motion becomes evident when a player kicks the ball into the air. The launch angle, or the angle at which the ball is kicked, plays a crucial role in determining the trajectory of the projectile. As the ball soars through the air, influenced solely by gravity, its motion can be dissected into two independent velocity components: the horizontal and the vertical.
Horizontal motion, governed by the initial kick, maintains a constant velocity throughout the flight of the soccer ball.

ATP Yield
69.7K
Cellular respiration produces 30 - 32 ATP per glucose molecule. Although most of the ATP results from oxidative phosphorylation and the electron transport chain (ETC), 4 ATP are gained beforehand (2 from glycolysis and 2 from the citric acid cycle).
The ETC is embedded in the inner mitochondrial membrane and is comprised of four main protein complexes and an ATP synthase. NADH and FADH2 pass electrons to these complexes, which pump protons into the intermembrane space. This distribution of...

Production Efficiency
16.9K
Net production efficiency (NPE) is the efficiency at which organisms assimilate energy into biomass for the next trophic level. Due to low metabolic rates and less energy spent on thermoregulatory processes, the NPE of ectotherms (cold-blooded animals) is 10 times higher than endotherms (warm-blooded animals).

Potential Energy
38.5K
The energy stored by a structure and location of matter in space is called potential energy. For instance, raising a kettlebell changes its spatial location and increases its potential energy. Similarly, a stretched rubber band contains potential energy which, under certain conditions, can be converted into other forms of energy, such as kinetic energy.
Chemical bonds that form attractive forces between atoms also contain potential energy, called chemical energy. When a chemical reaction...

Projectile Motion
15.3K
An object thrown in the air follows a parabolic path under the influence of Earth's gravitational force. The motion of such an object is called projectile motion, and the object itself a projectile. The parabolic path followed by the projectile is called the trajectory. Some common examples of projectile motion are the launching of fireworks, a golf ball in the air, meteors entering the Earth's atmosphere, and the firing of bullets.

Kinetic Energy
39.0K
Kinetic energy is the ability of an object in motion to do work or enact change. It can take on many forms. For instance, water flowing down a waterfall has kinetic energy. In biological systems, particles of light travel and are absorbed by plants to create chemical energy. Animals consume the chemical energy and give off molecules that carry their scent through the air. They also generate kinetic energy when they run away from predators. Entire systems also possess kinetic energy, like the...
