Powersprint®- strength training for power, speed and technique
Strength training for power and speed with specific motion patterns.

Powersprint - explosive maximum- and speed strength training. Sprint specific strength exercises for power and speed.

Powersprint is used and have a significant importance even on international elite sprint level. This is now confirmed and the truth. Weight lifting with a Powersprint machine improves specific muscle strength needed to perform the support phase in the sprint step with more power and with the correct technique. In the book "Strength Speed" fully motivates why this machine is such a valuable strength trainings tool for sprinters - a muscle specific link to plyometric exercises and to real sprint running.
Note!! Here you could download, these days updated again, the whole E-book:
Strength Speed E-book.pdf
You could also here as a speedier alternative download seventy specially selected pages from the E-book: Strenght Speed E-book. Specially selected pages.pdf
The book Strength Speed is constantly updated (lately now this year in January) and as a spiral-bound black and white book I also here warmly recommend to order. The book can be useful for coaches to deal with modern sprint technique and how to specific exercise in the strength room.

.It describes the sprint technology, but also scientific basic facts. The book including the manual of the Powersprint machine and appendices showing all new specific sprint exercises as well as eccentric exercises for more power and for injury prevention. Note here how many ways - also with basics exercises - you can use the Powersprint. The sprint step occur with an important edge insertion of the foot, as well as a special lateral hip work that only with difficulties can be performed with conventional weight lifting exercises. Hips (Pelvis sides) are rotating in an oval-shaped moving. Lower down on the page is also a movie clip that shows this edge insertion and rotating. Now you can specific develoup strength in this very important sprint detail in the strengthroom. Of course you also can powersprint with some specific natural scating in the start phase.
Here also a new offer!
Now the machine also could be delivered with a special leverage mechanism for more general training of gluteus and hamsting. (see last film clip at this page). See the color image on the last selected page here. The machine for Powersprint strength training is solid handmade in a very robust design. With its many moving parts it is finely mechanically designed, functionally tested after many years of experience.
Power Sprint is also EMG-tested in comparison with conventional strength exercises. Note at page 80 the huge activity from the hip extensors semitendinosus and adductor magnus. Important muscles needed for the crucial horizontal force of sprint speed. Read the link lower on the page: "Interesting research" on the importance of the horizontal force.

The pictures shows here powersprint training with lighter weights for speed strength.


Focus - "explosive" force and power
Schematic drawings. Max speed sprint with Power Sprint machine in comparison with real max speed sprint, Biomechanically analyzed. Line drawing (author) and processed diagram and data (Ralph Mann). With only 32 kg weights load the author (at body weight 67 kg) measured 120kg vertical pressure at Isometric stance in front support phase. It would be easy for an strong elite sprinter to come up to the average 165kg (see diagram) with Powersprint machine.

Powersprint offers now a new EMG-tested way to specifically train "explosive" maximum- and speed strength. Powersprint can contribute to excellent results for both the elite and youth sprinters but can also be particularly suited for masters. The training is similar to sprint running with resistance, but occurs in a weight-loaded leverage device in which also upright maximum phase sprint with very heavy weights can be used. This for development of explosive maximum strength with focus of horisontel forces produced by the specific muscles for this end. In the text you see this fact in an EMG-test. Perhaps you then ask yourself: Shouldn't Olympic lifting, which so far has been the most widely used form of exercise, be largely complemented by such a specific one leg exercise close to sprinter technology? This EMG-test also suggests that Sprint Power is a excellent all-round training tool for the specific strength for sprint speed. This is reported in the book at page. 80-81). Note also that Powersprint could be preventing Hamstrings ruptures (see pages 60 and 79)

In order to justify the use of a powersprint, study the section sprinter technique in the book "Strength speed" - now the illustrations are more developed to the better I hope. Illustrations which specifically shows Pelvis posture and sprint mechanics analysis. The sometimes downloadable E-book have also some of the illustrations in color . 45, 47, 50, 54 but in particular 59, 59 where with text and pictures different sprint models are described and how these could be trained with Powersprint. Note: Now, even the quadriceps dominant model could be trained. Pages 60 and 79 shows a new "total" Powersprint exercise. With film clips examples are shown here using Power Sprint, which thus means realistic weight loaded sprint motion in a specially constructed leverage device. This can be loaded with both lighter and very heavy weights.


Powersprint could develop:



Lisa Warfvinge, Swedish youth champion (age 16) Indoor SM 60m Outdoor 100m and long jump (5.96m). Silver at age 18 Indoor Junior-SM 60m. . Here speed strength training, long jump take off.


Anton Sigurdsson, now second best 400m sprinters in Sweden. Here Powersprint, acceleration I, the first steps to 15-25m.

Explosive strength training in the general period. Certain,
but because focus of improving the relative strength, really moderate hypertrophy
Here specific max phase sprint: 2-4x5-6rep /70-80%RM


Unique: "inward rotated over big toe" (study above Speed, technique.pdf


The new multi machine completed with a special leverage mechanism, here as a prototype,
for more general training of gluteus and hamstring. Could be delivered if you wish to have this completing.
