This week\u2019s guest is 安迪·艾格斯（Andy Eggerth）, head track coach at Kennesaw State University where he works primarily with multi-event athletes.\u00a0 \u00a0Andy is also a coaching educator as he is an instructor for the USTFCCCA Coaches Academy and has written the physiology curriculum.\u00a0\u00a0 I first found Andy through an incredible presentation of his 上 a variety of restoration means for speed and power athletes through the USTFCCCA website. Andy has been a contributor to Just Fly Sports in the past with a fantastic Q&A 上 the subject of lactate in speed-power development.\u00a0 It\u2019s kind of counter-intuitive to think that some athletes might actually need a small to moderate dose of speed-endurance work to be at their fastest, or jump highest, but as long as I\u2019ve been a coach, I\u2019ve seen this in action (many of those years without knowing exactly why) for over a decade now. Andy does such a great job of taking physiology and making it interesting in regards to the demands of sport.\u00a0 If my exercise science courses in school were more like the work Andy does, I would have been a kid 上 Christmas day for each class. For the podcast today, Andy expands 上 some points he covered in his original article 上 Lactate, and also covers a lot of other important topics, such as individualization of training, career and seasonal periodization, potentiation, neurotransmitters, plyometrics, and more.\u00a0 This episode is 上 e of the best blends of science and practice that I\u2019ve been able to record, as Andy is such a tremendous resource in this area. 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: \tAndy\u2019s background in coaching \tKey factors in individualizing training for speed and power athletes \tOff-season vs. In-season training ideas in terms of volume, intensity, and overshoot \t\u201cCareer\u201d periodization \tStrength training differences between freshman, upperclassmen and post-collegiates, as well as throughout the season \tThoughts 上 potentiation and performance \tNeurotransmitters and related recovery and readiness implications \tLactate benefits, and lactate shock as a technical inhibitor \tLactate response across a spectrum of athletes \tYearly periodization for plyometrics \u201cToo often, we as coaches get caught up in \u201cthis year\u201d, we want them to win the championship, get a PR, break a record.\u00a0 We lose sight of the big picture when we are too narrow focused.\u00a0 If we want a high peak to the pyramid, we want a broad base to the pyramid.\u00a0 I think that broad base is having sound fundamentals, techniques, mechanics and work capacity that is specific to the sport you are doing\u201d \u201cWith our post-collegiate athletes that are very highly developed, we\u2019re just touching 上 absolute strength to make sure we are going to maintain those levels, but not trying to gain more.\u00a0 Sometimes the weightroom even goes more recovery in nature with those post-collegiates to prevent injury since they already have such high levels of power output\u201d \u201cWhen athletes get into overtrained states, serotonin levels rise\u201d \u201cIf you really tax the central nervous system, it might take you 7-10 days to recover\u2026 whereas metabolic fatigue, usually 24 hours, 48 hours at most you\u2019ll bounce back.\u201d \u201cLactate is a very positive (fuel) source for us\u201d \u201cIf you have a lactate workout 上 Monday, you might have that lactate shock, and kill skill development 上 Tuesday, Wednesday because of that lactate shock\u201d \u201cBoo\u2019s talked about (skill in states of duress) training proprioceptors, if you do a heavy squat workout and then do hurdle mobility afterwards, you\u2019ve fried proprioceptors, and now you have rely 上 some other 上 es to get through the hurdles with skill and coordination\u201d \u201c(Compared to some fast-twitch, powerful athletes) Some athletes produce almost no lactic acid during acceleration development\u201d \u201cWhen we got away from stimulating the endocrine system strong enough (this athlete) began to look like garbage\u2026 with this type of athlete, we need to keep stimulating the endocrine system\u201d \u201cSome people respond well to the tempo running\u2026what I typically find, it seems like it is your lower level athletes that are going to respond better that way.\u00a0 Your high caliber athletes are not going to respond well to a lot of tempo, it\u2019s going to blow them up\u201d \u201cWomen are usually going to get a little better testosterone stimulus from doing higher sets, higher volume, and a little lower intensity; when they go really high intensity and real low volume, the women\u2019s testosterone levels tend to come down a little bit\u201d \u201cI do (drop jumps) pretty sparingly, but I do use them because I like to touch 上 the golgi-tendon organs\u201d About 安迪·艾格斯（Andy Eggerth） 安迪·艾格斯（Andy Eggerth）, a nine-time Atlantic Sun Coach of the Year and 2013 USTFCCCA South Region Coach of the Year, is the Director of Track and Field and Cross Country at Kennesaw State University. During his first five years at Kennesaw State, Eggerth has had tremendous success with both the cross country and track and field programs. He has coached 15 所有-Americans since coming to KSU, and his teams have won eight Atlantic Sun Conference Track and Field Championships and 上 e Cross Country title in 2010.
