Innovation in Physical Preparation and Technologies for Sports Performance
Innovation at the service of performance and reathletics
Innovation from the field is the driving force behind constant progress in all areas. By observing, listening and reflecting directly on the ground, ideas emerge naturally, shaped by the concrete challenges encountered.
This is where creativity meets reality, generating practical and innovative solutions. This approach, anchored by experience and expertise, makes it possible to anticipate needs, identify opportunities and create appropriate responses. It embodies the collaboration between experts and practitioners, combining progress in the service of efficiency and continuous improvement.
My greatest innovation is the HS2. For the record, the name comes from HamString Hors Service: HSHS = HS2.
This device is developed in the Pallini premises, a 100% MADE IN FRANCE machine. For the other innovations, you will have a brief description in the various areas investigated.
The HS2 machine (HamString Hors Service) is a patented innovation, 100% MADE IN FRANCE, designed to optimize hamstring rehabilitation.
Patented in 2019, the particularity and innovation of this device lies in the movement of the carriage up to under the footrest. By having the feet fixed, the latter allows the TOTAL work of these muscles in all the amplitudes of the knee. The work can be progressive in intensity as well as in angular variation. The strengthening in Concentric, Eccentric or Isometric are modular as well as the support of the different muscle heads by the tibial rotation under femur. The work can be carried out with two feet as with one foot. It is possible to accompany the athlete in the concentric phase or to accentuate the eccentric work by accelerating the speed of the carriage in its return stroke.
It will allow an effective and rapid return of the hamstrings removed during ACL operations with the so-called DIDT method or in the prophylaxis of hamstrings in pivot sports or even in high kinetic sports such as athletics.
Different methods are available to you thanks to closed or open pelvic work, on one leg or two legs.
Working with the closed pelvis will allow the IJ to be activated for the purpose of stabilizing the knee and the work will be felt at the level of the distal myotendinous junction. Working with the open pelvis will optimize the action of the IJ in hip extension and thus the muscular body and the proximal insertions will be felt.
In order to add comfort of use and more intense use, the backrest and footrest are reclining. This machine is one of the best tools for strengthening, progression or prophylaxis purposes.
It will find its place in your room and will easily replace classic machines such as the leg curl or on the bench lying on the stomach. This device promises better results than with the Nordic Hamstrings method.
Tested on high-level athletes, they felt the effects quickly. As proof, you will find below a small study showing the effectiveness of this machine. I tested the effects of the HS2 on a high-level injured audience. I carried out an isokinetic test pre and post strengthening of the Ischios exclusively in concentric contraction.

In 2014, INSEP created a working group to develop a software for re-athleticization support. Many colleagues got involved in the adventure, such as Christophe KELLER, Eric COURVOISIER, Pascal ROUSSIN, Cécile SAVIN, Etienne ELLIN, Anne-Laure MORIGNY and myself, under the direction of Norbert KRANTZ.
The software was recently released and can be used by organizations such as CREPS and Olympic Sports Federations.
Following research conducted at the National Ski and Snowboard Center (CNSS), I developed a new innovative approach to enable more effective and efficient altitude acclimatization than traditional acclimatization.
We worked with the Altitrainer machine connected to a mask and a nitrogen bottle. We simulated an altitude of 3500m and carried out work based on the FR (Respiratory Frequency). The latter considerably increases hypercapnia and leads to respiratory and metabolic acidosis. The lactate index recorded was around 6 mmol while the effort is targeted at the Ventilatory Threshold 1 - 30% or a Heart Rate of 110bpm...
This is a different method from that proposed by Dr Woorons or that of hypoventilation caused by a mask. The physiological adaptations are really felt following this form of work.
The rest? Maybe in a scientific article, who knows?
Here I share with you the development of an isokinetic test focused on prophylaxis in mogul skiing. The latter was part of my thesis development for my Master 2 EOPS.
Indeed, when we analyze the activity, we realize that the mechanics and speeds are demanding and not necessarily tested in the best possible way. Thus, depending on the angles, speeds and activities, I deduced and proposed a test that was validated for the jury of his Master 2.
Where did it start? We can see that right away...
The starting point of this development comes from the observation and analysis of the activity.
Let's take an international-level male athlete and observe his movement... It is about knowing the travel between the hollow of the first bump then the peak and from the peak to the hollow of the next bump. In the images opposite and according to the following anatomical points: Coxofemoral / Center of the tibial plateau / External malleolus, we find a value of 131° of knee flexion against 87° on the other image. We then find a movement of 44° when raising the knees; but we must take into account the extension of the knees until the next point of impact.
At the same time, we recorded a sequence of 15 bumps crossed in 5.1 seconds.
The angular speed of crossing a bump by this athlete is therefore 258°/s.
In this isokinetic test, we also took into account the prophylactic aspect with the IJ/Q ratio at 60°/s and then carried out a verification of the mixed ratios.
Finally, the joy of seeing this protocol work wonderfully and above all very useful for current and future mogul skiers!
Where does this method come from?
By reading many books on the subject, I adopted centralization and reflection. The centralization of key information on the mechanics of the human body as well as muscle insertions and trajectories. This centralization was long and laborious since many methods are developed and all offer a clear vision of a single process. I built an assessment model by picking up information here, another there and then relating each piece of information in the direction I wanted to go.
8 years and more than 700 assessments later, I have developed a method that works. This method starts from the mechanical analysis of the pelvis to deduce the work to be put in place on the rest of the body. Indeed, the assessment once drawn up gives very precise information on the organization of the skeleton, the remediation of the various imbalances consists of precise work on the stays. Some will say that playing on the muscular aspect does not work and is not a sustainable method. People who have used this method will tell you the opposite. Some of them who could no longer run or ski in low angles can do it today!
