This week\u2019s guest is 卡尔·瓦勒 of Spikesonly.com. Carl is, amongst other sprint and hurdle coaching talents, a speed technology expert.\u00a0 A current trend in athletic performance is jump testing, both as a means of assessing physical progression over the course of a training year, as well as a way of seeking to balance out athletes for the prevention of injury, and potential optimization of performance. The vertical jump is the greatest display of power that an athlete can generally produce, so it does make good sense to have adequate knowledge regarding testing and assessing the movement. \u00a0After all, \u201cwhat you measure, you improve\u201d. There are a lot of opinions 上 the best way to test power through the vertical jump, so Carl and I cover a lot of ground 上 this topic in this podcast.

Today\u2019s episode is brought to you by SimpliFaster, supplier of high-end athletic development tools, such as the Freelap timing system, kBox, Sprint 1080, and more. Key Points: \tThe basics of using vertical jumping as a means of assessing athletic preparation \tConsiderations with the novelty factor in jump training \tGuidelines in deciding which jump monitoring system to utilize \tWhy Carl likes repeated jumps vs. single efforts in testing \tPro\u2019s and con\u2019s of accelerometer based testing \tThe advantage of jump testing with added barbell load \tEmbedding tests as a part of the warmup \tHow and when to test jumping for team sports vs. track and field \tUtilizing jump testing in context of strengths vs. weaknesses, and \u201cbalancing\u201d the force-velocity jump profile of athletes \tHow to determine what is necessary to train for, and what data 上 e should collect over time \tThe relationship between athletic structure, sprint testing and vertical jump performance \tWhy Carl likes a plethora of jump tests in training and assessment \u201cThe first time you get 上 a force plate or jump mat, you\u2019re excited, and want to know your numbers\u2026. but you start to get bored, and want something different or not at all\u2026 jump testing requires an all-out performance to be valid\u201d \u201cWhen there\u2019s lines (for testing), people aren\u2019t learning and moving and getting better\u201d \u201cYou should be video taping jump testing\u201d \u201cAccelerometers, because they\u2019re cheap, you can make devices really easily.\u00a0 We\u2019re going to see less physical pads or plates, and a lot more sensors\u201d \u201c(knowing wattage) resets people\u2019s perception of the numbers\u201d \u201cIn sports preparation, you always want to contrast what they\u2019re not getting.\u00a0 So basketball players, there is a joke that it is the \u201cno barbell association\u201d, testing vertical jump with a barbell reinforces the cultural side of what we\u2019re trying to do\u201d \u201cMy rule is to make sure the tests are embedded (as part of the warmup)\u201d \u201cRate of force development, you have to be careful, because you have to do a lot of teasing out to get there\u201d \u201cIf you don\u2019t think it\u2019s going to improve, don\u2019t test it\u201d \u201cTraining data trumps monitoring every single time\u201d \u201cThe most humbling experience you can do, is have athletes to do a 2-point leaning stance, and time them, because you won\u2019t get the artificial benefit of learning to accelerate better from a mechanically efficient position\u201d \u201cMaximum velocity is the most wonderful test; I\u2019ve seen guys with awesome 20 meter tests, and the look great, get cleared, but then they get hurt\u201d \u201cYou need to start profiling with greater precision than \u201cwhat\u2019s your 20 time?\u201d\u00a0 (This is where a device like the 1080 sprint really shines) About 卡尔·瓦勒: Coach Valle has coached Track and Field at every level, from high school to the Olympic level in the sprints and hurdles.
