Similar to building explosive power by jumping over a stationary object, hurdles allow you to practice your leap. Space eight flights of hurdles two feet from each other and aim to jump over each like a pogo stick—basically, as high as you can. Repeat this for 10 repetitions: one flight of eight hurdles equals one repetition. Do this twice per week.
The vertical jump involves coordinated spine, hip, knee, and ankle extension to produce force in a vertical direction very quickly, while the muscles are shortening through to a very short muscle length. Since the time available for producing force is long compared to other athletic movements, this reduces the importance of rate of force development. Yet, the force-velocity relationship is the primary determinant of the amount of force that can be exerted at a given movement speed. Therefore, maximum force, velocity, and the force-velocity gradient all affect vertical jump height.

Randomization was performed in computer-generated, permuted blocks of 6 to 10, stratified according to the participating ICU. Treatment assignments and a five-digit reference number were placed in sealed, opaque envelopes, which were opened by the person responsible for the preparation of the trial-drug solutions. The solutions of norepinephrine or dopamine were prepared in vials or syringes according to the preference of the local ICU. Each vial or syringe was then labeled with its randomly allocated number. The doctors and nurses administering the drugs, as well as the local investigators and research personnel who collected data, were unaware of the treatment assignments. The trial was approved by the ethics committee at each participating center. Written informed consent was obtained from all patients or next of kin.
During the takeoff an athlete generates forces that ultimately result in a vertical velocity high enough to leave the ground. We have shown before, that this vertical velocity reaches 0 at the peak of the jump, and it is easy to show that the velocity is exactly the same during landing as it was during takeoff (but directed in the opposite direction).
My warmup on March 29, following a day of recovery, left me feeling hoppier than I’d expected, and not nearly as achy. After 10 devastating near misses, and several others that weren’t as close, Jeff lofted the best lob I would see during this journey. I leaped, controlled it with one hand and—boodaloomp—in and out. I could have wept. “You got this!” Jeff implored. “You know you got this!”
For women's basketball, to dunk or not to dunk has long been the question. It’s the ‘wow factor’ that WNBA haters often point to as proof that the women's game doesn't deserve the fandom, fame and fortune that the guys get. Cristen and Caroline talk to two dunking superstars of past and present to sort through the courtside gender politics and controversy of stuffing the net and find out whether more women bringing the slams could settle the score.
Perform the routine every second day to give your body a days rest in-between workouts. This means that on week one you’ll be training 4 times a week, week two you’ll be training 3 times per week, and on week three you’ll be training 4 times per week. That ends up being 11 workouts per phase for a total of 33 workouts in the program. Also, during this program you will be taking one week off between each phase to let your body completely recover. You need to give your muscles time to fully repair in order to grow stronger and more explosive.
