I am a High School Strength and Conditioning Coach, working with 13 different sports throughout the year. Most coaches are pretty "hands off" (which I prefer) and just let me do my thing. However, the football coach is very hands on, and frustrates me beyond belief. I am pretty vanilla with football. Hang Cleans or Cleans on explosive days where we focus on speed of movement and plyometrics. Snatch movements on lifting days where the focus is strength development. Squats, Bench, Rows, etc are on those days. He has finally become OK with this as the athletes have made tremendous improvements doing this for the past 2 years (using a linear periodization model throughout the year). However, NOW he is into isometrics to build "mental toughness" (because it hurts). He wants the athletes to hold a squat position for 2 minutes, followed by a 1 minute rest and repeat it 3 times a workout. I told him that isometric training would have a detrimental effect on speed and explosiveness. He said, "prove it"... Which brings me to you. Is there any research out there that shows the effect of isometrics on speed and explosiveness? My gut tells me there must be, but I have not been able to find anything...
Thanks for the help!
