Today\u2019s guest is 约瑟夫·科恩, exercise physiologist and sport scientist from Gold Coast, Australia.\u00a0 Joseph is a well-rounded performance coach who has spent a lot of time recently in the realm of training world-class track and field sprinters and jumpers in China. I don\u2019t remember exactly how I came across Joseph\u2019s work, but the quality of his training videos are first class and I know he has also had tremendous mentors in the field, such as working with Randy Huntington.\u00a0 From altering the paradigm 上 jump mats and testing, to resisted and assisted training, as well as special strength work in the gym, I\u2019d been really looking forward to having Joseph 上 this podcast for some time. Joseph is currently the Physical Preparation Coach for the Chinese Athletics Association's jump & sprints section; where he handles the rehabilitation and strength & power training for China\u2019s best track & field athletes.\u00a0 Many of those he worked with had world top-20 marks. \u00a0Previously, he was the Performance Manager at the Chinese Olympic Committee\u2019s National Sports Training Centre in Beijing in the lead up to the Rio Olympics.\u00a0 He also spent time as a performance manager with the Chinese Olympic committee through EXOS, and had a long-running performance clinic in Queensland. Topics we\u2019ll cover today are numerous, and will include sand sprinting, special strength for sprinters and jumpers, ideas 上 maximal strength for sprint athletes, complex training, ideas 上 jump training and the \u201cmaximal displacement\u201d theory, hamstring training, and Joeseph\u2019s work with the 1080 sprint and kBox. 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: \tJoseph\u2019s background as an athlete and as a coach \tSand sprinting for track and field sprinters \tStrength and special strength for sprint athletes \tTakes 上 maximal strength training for high-end sprinters \tWhen and when not to use complex training means \tMaximal displacement as opposed to a simple RSI test in vertical jump work \tUsage of the 1080 sprint and kBox in training sprinters and jumpers \tHamstring training and injury prevention \u201cYou can have awesome, (ideas for progression) in the weight room, but sometimes, you have a hamstring problem!\u201d \u201cMy non-technical training is really simple, it\u2019s either a max strength day, or it\u2019s a power day\u201d \u201cI think instead of an RSI, look at maximal displacement at certain contact times\u201d \u201cYou look at (the contact times for your event) and try to maximize displacement at those contact times\u201d \u201cI couldn\u2019t do too many Nordic hamstrings with the guys because it would blow them up the back of the knee\u201d \u201cOne thing with all the fascial length research is that isometrics can actually shorten the fascial length which may predispose you to injury; eccentrics definitely seem to lengthen it\u201d \u201cI go with a low volume approach for Nordic hamstrings; starting with 2 sets of 2\u201d About 约瑟夫·科恩 约瑟夫·科恩 is an exercise physiologist and sport scientist from Gold Coast, Australia. \u00a0He is currently the Physical Preparation Coach for the Chinese Athletics Association's jump & sprints section; where he handles the rehabilitation and strength & power training for China\u2019s best track & field athletes. \u00a0Previously, he was the Performance Manager at the Chinese Olympic Committee\u2019s National Sports Training Centre in Beijing in the lead up to the Rio Olympics. \u00a0Athletes supported by this program won 34 medals (including 19 gold medals) at the 2016 Olympics. \u00a0As a speaker, Joseph has lectured at a number of international conferences including in China, United Kingdom, United States, Australia and New Zealand.
