You were introduced to strength and power in part one of the series on the science of training the young athlete. We will now delve a little deeper into this important aspect of preparing athletes for the participation in this sport. Many sport skills cannot be proficiently perform without some level of appropriate strength and power. When it comes to sport skills, makes them strength is generally no win near is important is optimal strength enough and I'm going to take some time over the next four lectures to illustrate this. We'll also discuss power and how you train power, so the resulting adaptations directly transfer to the athlete's sport performance. That is we will examine how we ensure specificity of the exercises you select to develop the athlete's strength and power, so there is a high transfer effect. We will also examine the important role played by the nervous system and the effect of application of strength, and power. Now, watch any slow motion video of a sports skill and the importance of the nervous system is easy to see. The athlete's strength and power is irrelevant, unless the brain can coordinate the muscles controlling the body parts in intricate and precise ways. The timing and the sequencing of the lens in conjunction with the torso positioning relies on the ability of the brain to recruit sufficient muscle fibers at exactly the right time. When the brain coordinates muscles and fibers and applies the power to perfection, the athlete's performance of the skill is truly beautiful to watch. Now there are many apps available that allow a coach to video an athlete while they're performing a skill and it is then possible to use the video to measure joint angles, and make a side by side comparison with an elite athlete. Some apps are sufficiently sophisticated to provide limb velocity and acceleration, as well. Both of which are indicators of the athlete's strength and power. We also have wearable technology available that's gradually becoming a bigger factor in providing data about the athlete's performance. However, many coaches are unable to make much sense of the data, because they're unfamiliar with the fundamental strength and power concepts. In this lesson, we will address these concepts, so you can successfully use the sport performance analysis tools available to you and access how you need to adjust the athlete's training. The main focus of this lesson is on introducing you to the critical strength and power terminology. We will examine how strength indicators, such as force and work and torque and power and endurance enable the application of the optimal proportion of strength and power needed to produce a perfect athletic skill. We'll also address muscle action terminology and explain fundamental strength, and power quantification procedures. So, let's get started.
