Hello Alex, been trying out the running overcoming isometrics recently and it’s been helping with speed improvement. I have a question regarding your thoughts on single leg squat iso and producing 5-6 times body weight for elite sprinters. When you calculate that are you using your method of single leg squat iso push, an example, a 100kg athlete puts an additional load of 100kg on the bar, and then it’s equivalent to 3x body weight, so if 200kg in on the bar, then it’s 6x body weight? Is it also the same if instead of using weights you just hit 200kg on the force plate? Or is it the 100kg athlete hitting 500kg on the force plate, then you’re saying he’s 5x body weight? Thank you for putting out great content, helping athletes get better. Just a little bit confused of how you calculate when an athlete is at 5-6x body weight for a single leg squat. Is it 6x when the 100kg athlete sl squat 200kg, or 600kg
Thanks for the question mate. The 5-6xBW load is whats measured on the force plate. Therefore, it is inclusive of the mass of the athlete. When we work out what load the athlete has to use in an Iso-Hold (yielding iso) we must minus body mass off of the total force plate output. Eg. 300 kg measured on the force plate in an iso-push for a 100 kg athlete means a 200kg external load. Hope this make sense.
