竞技表现优化竞技表现优化

背景情况:

手球投速度对于表现至关重要.
了解上肢机械性能与投速度之间的关系对于有针对性的训练至关重要.
之前的研究已经探索了各种生物力学预测因素,但动态运动的力-功率-速度 (F-P-V) 变量的具体贡献需要进一步阐明.

研究的目的:

在手球运动员中,研究从弹道板压力投 (BPT) 中获得的FPV机械变量与肩膀异动力旋转强度与投速度之间的关系.
确定哪些FPV变量对立式和三步式投中最大投速度的最好预测.

主要方法:

27名经验丰富的男性手球运动员参加了比赛.
力量-功率-速度 (F-P-V) 变量 (理论上的最大力[F0],速度[V0],功率[Pmax]) 在单臂弹道板压力投 (BPT) 过程中被测量.
评估了肩膀内旋转强度的异动力学. 投速度测量的是站立和三步投. 根据投表现,球员被分为"高/快"和"低/慢"组.

Motion of a Projectile

Motion of a Projectile

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.

Force and Momentum

Force and Momentum

Force and momentum are intimately related. Force acting over time can change momentum, and Newton's second law of motion can be stated in its most broadly applicable form in terms of momentum. Momentum can be applied to systems where the mass is changing, such as rockets, as well as to systems of constant mass. Also, momentum continues to be a key concept in the study of atomic and subatomic particles in quantum mechanics. One can consider systems with varying mass in some detail; however,...

Velocity Potential

Velocity Potential

In steady, incompressible flow through a long, straight pipe with a uniform cross-section, the flow in the central region (far from the pipe walls) is irrotational. This irrotational nature means that fluid particles do not rotate around their axes, and a scalar function called the velocity potential, represented by ϕ, can be used to describe their movement. In irrotational flows, the velocity field V is defined as the gradient of the velocity potential:
