Use a smaller ball. It's much easier, when you're first starting out, to try dunking with a smaller ball. You'll be able to palm it more easily and control your approach, making the maneuver more satisfying and your practice closer to the real thing. Continue dribbling and shooting exercises with the appropriate-sized ball so you're not getting too used to the "wrong" size, but keep a small ball around for your sick dunks.[1]
Another high pull option is to shorten the range of motion to make it a hang high pull instead of a power high pull (“power” implying that the load starts on the floor). In this case, the start position is from standing, with the bar hanging in front of your thighs at arms’ length. The movement is initiated with a dip in the hips and knees, so that the bar lowers to just above knee level, followed immediately by an explosive pull.
Also, using the lifting (concentric) phase of these exercises only, rather than both lowering and lifting phases, *might* further improve results. This is partly because lifting phases involve faster rate coding, and partly because this strategy might potentially help avoid optimizing stretch-shortening cycle function for lifting heavy weights, rather than for jumping.
Less helpful was my early realization that I was a two-hand dunker, in light of my inability to palm a basketball on the move. It’s common knowledge among dunkers that throwing down with two hands is typically harder than with one; the former requires a higher vertical leap. So as I flailed haplessly at the rim last spring with one hand, I felt not just discouragement but also fear. Fear that I would miss big chunks of my kids’ ninth, sixth, and first years on earth just so I could come up embarrassingly short on a senseless goal that my wife and I would later estimate consumed 15 to 20 hours a week, on top of my normal work hours. And fear that I had shared this idea with my editors way too soon.
This book is great. I was a little worried because I am a girl an wasn't sure if these excerises were gonna be too hard or effective. But Jack Cascio shows great exercises and explains the science behind vertical jump. He explain the exercises step by step and give you a website where to go if you need a visual. Very informative and great info. Will definitely help you increase you certain will you help you gain knowledge about it also.

We purchased this because of its safety evaluation and the high ratings. I did evaluate the negative reviews and was prepared for the issues reported, however; I found none of the comments in the negative reviews to be valid with our experience. First, for the people who complained about the assembly instructions- there are pictures....yes, the English is horrible, but there are pictures! Total assembly time, with one human, was 2 hours and 10 minutes. Assembly of the safety cage was the the most difficult part. Specifically, the foam comes in two sections, which makes it difficult to slide into the pocket. BUT, with a little patience it can be done. Second, to those who would rather purchase a unit from Walmart- this is a very fine product, with consumer quality pieces, they include gloves, spring tool, and a ladder- you don't get ... full review

I have to admit...I bought this for my 5 year old son, but I found it to be just as enjoyable! Setup took a matter of minutes before he was launching his first rocket in the air. he was impressed with the THUMP followed by a dissapearing act as it launched into the sky. After he had a few tries it was my turn, I assumed it would not handle my 200lb frame very well so I started light and worked my way up to an all out double foot stomp that left craters where I landed. The SQUEEEEEL from my son as the rocket nearly "went to the moon" was priceless. We lost a few rockets that day to rooftops, damage from landing on pavement, and one down a difficult to repeat sewer drain. I advise to have the little ones wear safety ... full review
variations: The vertical jump test can also be performed using a specialized apparatus called the Vertec. The procedure when using the Vertec is very similar to as described above. Jump height can also be measured using a jump mat which measures the displacement of the hips. To be accurate, you must ensure the feet land back on the mat with legs nearly fully extended. Vertical jump height can also be measured using a timing mat. The vertical jump test is usually performed with a counter movement, where there is bending of the knees immediately prior to the jump. The test can also be performed as a squat jump, starting from the position of knees being bent. Other test variations are to perform the test with no arm movement (one hand on hip, the other raised above the head) to isolate the leg muscles and reduce the effect of variations in coordination of the arm movements. The test can also be performed off one leg, with a step into the jump, or with a run-up off two feet or one foot, depending on the relevance to the sport involved. For more details see vertical jump technique.
Dunking isn’t much different. You’ll likely find yourself getting slightly higher with each attempt at first, but before long, fatigue will set in and your vertical leap will decrease. At this point, it’s a good idea to end the session, rather than try to push through and force yourself to jump higher. It’s an indication that your nervous system has mustered all the energy it has to help you jump, and you need to let it rest. Give your legs a couple days’ off, then come back again and try.
My quest to dunk started poorly. The main problem was that I could only do about half of the very long list of ercises the Jump Manual instructed at the crowded and inadequate YMCA near my place. The basketball court—the only space big enough to do some of the drills—was always occupied with classes. The Strength Shoes, meanwhile, were so absurd that I was too embarrassed to wear them in front of other gym-goers. I used them only a handful of times, in an empty stairwell on the top floor of the gym.
“No, not Dad,” Oliver said in the brick tract home where he grew up. “He was an older dad, like you, and his family was the focus of his life. The only time he wasn’t home with us kids was when he went out on the road for Phillips Petroleum, buying and selling leases in western Kansas and Oklahoma. When he got back he’d say, ‘All I wanted to do was come home.’ ”
I learned that insects are fucking awesome. There was an insect in particular that I was interested in called the froghopper, or spittlebug, that is basically one of the world’s top jumpers. It’s a survival mechanism. It can jump far, far higher than we can as a function of its weight, basically. So I learned that humans are quite modest in the jumping scheme of things.
I tried to work out at least a couple of hours a day doing something or other. So some days were lifting, doing arm and core lifting. Again, you can imagine these sprinters, they’re strong all over — if you think of Tyson Gay or someone. It’s not just their legs that are muscular, it’s their arms, too, because they have to pump furiously to get themselves to go faster.
The player approaches the basket and obstruction, and then leaps. During flight, some portion of the player's body is elevated above the obstruction. This may entail raising the legs or some portion thereof in-air to soar over the obstruction. In other instances, the trunk-moves over an obstruction as the legs pass around it. Common obstructions include: motor vehicles; crouched, seated or standing person(s); ball rack; or other available objects.
When performing a vertical jump, the athlete exerts force at the low back, hip, knee, and ankle joints. The spine flexes as the athlete squats downwards, and then is extended by the spinal erectors over the course of the jump. The hip extensors (gluteus maximus, hamstrings, and adductor magnus) work to move the trunk and the thigh apart, which pushes the torso up and backwards. Meanwhile, the knee extensors (quadriceps) contract to extend the knee, and the calf muscles contract to move the shin backwards, towards the vertical.

An impressive vertical jump is the ultimate standard of lower-body power and explosiveness—an attribute that pays as many dividends in high-impact sports like basketball, football, and soccer as it gets you wide-eyed looks in the gym. Increase your hops, and chances are you’ll also be able to run faster, lift more weight, and maybe even throw down a dunk at your next pickup basketball game.
When tendons elongate to a greater extent during a jumping movement that is preceded by a countermovement, the muscle lengthens less. This produces two effects. Firstly, the greater elongation of the tendon means that more elastic energy is stored during the countermovement, which is then released in the subsequent jumping phase. Secondly, the smaller elongation of the muscle means that countermovement depth can be greater for the same shortening velocity in the subsequent jumping phase, because the muscle never lengthened that much to begin with. Since shortening velocity determines force, this allows the same muscle force to be produced, despite the larger joint range of motion.
Hi I'm 14 turning 15 this year with a height of 5'8-5'9 and a standing reach of 7'5. Right now I am 190 pounds.I know I'm not physically fit. I can touch the net by just standing and jumping but not the rim. I really want to dunk since my friends can reach almost the rim while i can't even if I'm taller than them. Is it an impossible dream to dunk before my high school life ends? Also it will be nice to hear on how to lose weight. Since people tease me on how fat I am. But i am currently trying to lose weight and lost 14 pounds already. The only problem is my asthma which is making it hard for me to do physical activities.
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.
Rope skipping is also a very basic form of a type of exercise called plyometrics. Plyometric exercises involve repetitive explosive movements, such as jumping up and down or catching and throwing a medicine ball. The idea is to execute the movement with as little downtime as possible between repetitions. This, in effect, trains muscles to be powerful and explosive, and utilize the kinetic energy inherent in athletic movements in the most efficient way.
