Bryan Johnson(@bryan_johnson):i’m training to dunk a basketball the odds don’t look good 48 yr old 6 ft 180 lbs standing reach 91” needed reach: 130” that’s a 39” vertical which exceeds ave nba player (35.5”) here are the thresholds I need to meet: > takeoff velocity 14.5 ft/s > ground force: 585 lbs > time to take off: 0.2 sec > peak power: 14.8 hp (11 kW) landing is even more intimidating > creates load equal to 6-10x body weight > 1,080 to 1,800 lbs of ground reaction force injury risk > 3-5x rupture risk for men my age > 1,080-1,800 lbs funneled via centimeter thick tendon > knees absorbing 7-9x body weight age disadvantage power+rate of force down 25-40% at age 48 what is your assessment, will I be able to do it?
