- 用力平台收集数据,分析了包括跳跃高度,冲动,力,反应强度指数和时间参数在内的变量.
主要成果:
- 在这三种条件下,在跳跃高度,制动冲动或推进冲动方面没有发现显著差异 (p > 0.05).
- 与CMJ-H和CMJ-N相比,CMJ-F条件导致显著更高的力变量和更改的反应强度指数,时间变量明显较低 (p <0.05).
- 在CMJ-F下,反运动深度明显较浅,在CMJ-H和CMJ-N之间没有观察到任何变量的显著差异 (p > 0.05).
结论:
- "尽可能快跳跃"的指令 (CMJ-F) 引起了更大的力量产生,但减少了在空中花费的时间.
- "尽可能跳高" (CMJ-H) 和"尽你能力跳高" (CMJ-N) 的指令导致更长的地面接触时间.
- 在CMJ测试期间口头指令的程序一致性对于准确解释运动员表现数据至关重要.

01:27Exercise and Muscle Performance
2.9K
Exercise induces a range of adaptations in muscle tissue, depending on the type and duration of activity. Such physical training can be broadly categorized into two types: endurance exercises and resistance exercises.
Endurance exercises
Endurance exercises involve running, swimming, or cycling, which require repetitive movements with low force output. When a person engages in endurance exercise, a few noticeable changes occur in their skeletal muscles. For instance, the number of capillaries...

01:17Force and Momentum
24.2K
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, the...

36.7K
Not all intergroup interactions lead to negative outcomes. Sometimes, being in a group situation can improve performance. Social facilitation occurs when an individual performs better when an audience is watching than when the individual performs the behavior alone. This typically occurs when people are performing a task for which they are skilled.

59.1K
Long-term potentiation, or LTP, is one of the ways by which synaptic plasticity—changes in the strength of chemical synapses—can occur in the brain. LTP is the process of synaptic strengthening that occurs over time between pre- and postsynaptic neuronal connections. The synaptic strengthening of LTP works in opposition to the synaptic weakening of long-term depression (LTD) and together are the main mechanisms that underlie learning and memory.
