Training & Testing

I've designed multiple training programs to elite athletes in order to increase their performance. My speciality is strength training and my method consist on designing individual training programs based on cutting-edge scientific tests to help athletes achieve their best shape. If you want to increase your strength-power-speed and train with state-of-the-art fitness programs, or want to evaluate your athletes fitness, contact me.


How i work

As a sport scientist, my training programs are based on the latest and more strong scientific evidences that have proven to increase physical performance. There are no miracle solutions, magical vests or secret recipes. You "just" need to understand the physiological basis of the human adaptations to training stimulus. Just like a physician does, i prescribe training loads with respect to systematic scientific testing that evaluate your physical capabilities and detects your deficits so you can optimize your performance.

Experience

I have tested several elite athletes, such as professional basketball or soccer players, world-class martial artists or high-level distance runners in order to evaluate their force production capabilities and orientate their training programs. I've worked as strength & conditioning coach for elite young basketball players and currently i'm designing the strength training programs of elite middle distance runners, such as the 2010 Track&Field 1500m European Champion, Arturo Casado.


Tests & Technologies

To achieve the best results, training programs have to be designed with respect to objectively measured physical fitness of the athlete. To do this, i use some cutting-edge technologies from the sport sciences laboratories (like the PUSH band, My Jump, PowerLift, Runmatic, linear transducer, photocells, radars, high-speed cameras, etc.) that can measure the physical condition of the subject in a highly precise way. Specifically, i can measure your force-velocity-power profiles on several resistance exercises (such as squat, bench press or cleans), your jumping abilities, your sprint mechanics or your degree of fatigue, so i can detect your deficits to design an individualized training programs to optimize your performance.

Training programs

Every athlete has his/her own strength requirements, fitness deficits and physiological adaptations, so training loads must be prescribed individually in order to obtain the best of each subject. According to that, each athlete needs different exercises, number of repetitions or training sessions per week. My strength training programs are unique for each athlete, and they consist on what is more beneficial to increase performance: multi-joint resistance exercise, plyometrics, sprints, sleds or ballistics that will boost your strength, velocity and power production.

My apps

I currently have 3 apps in the Appstore which measure different performance variables: My Jump 2, which provides a complete analysis of different vertical jump tests, Runmatic, which calculates running mechanics and PowerLift, which measures barbell velocity in resistance exercises and estimates the 1-RM in a highly accurate way. The validity, reliability and accuracy of the 3 apps has been proven in high-quality scientific journals. See the validation papers here.


My Jump 2 for iPhone & iPad

My Jump 2 is the new version of the award-winning app for iPhone & iPad that measures vertical jump performance in a simple, reliable and scientifically validated way. Available for iOS9+ devices on the Appstore.


How to use

My Jump 2 takes advantage of the high-speed camera on the iOS devices to record stunning slow-motion videos of your jumps. Then, you just need to select the take-off and contact frames and My Jump 2 will give you a reliable and valid jump height, just like the force or infrared platforms do. Moreover, My Jump 2 measures the force, velocity and power profile of your jumps, as well as other relevant variables such as contact time, vertical stiffness or the reactive strength index in a simple and accurate way. It works with any iOS 9+ device, although the best results are obtained with slow-motion devices like the iPhone 5s or newer, or the iPad Air 2 or newer.

The science behind My Jump 2

My Jump was scientifically validated with a 10.000€, high-tech force platform and the results were published on the prestigious Journal of Sports Sciences. We measured 100 different jumps both with My Jump and the force platforms and then we compared the jump height of each system. My Jump values were highly valid and as reliable as the those obtained with the platform, so it is a great tool to measure vertical jump performance for both scientific and training purposes.

My Jump allows me to measure my jump height easily and with accuracy. Something indispensable to evaluate my physical performance.

Luis Alberto Marco, 2009 European indoor 800-m Subchampion

My Jump is the cutting edge, scientifically validated and most practical application to measure athletes vertical jumping performance, and the only one to include the complete "Optimal Force-Velocity Profile" analysis we recently validated.

Frequently asked questions (FAQ)

What is new in My Jump 2?

Besides the accurate jump height and force-velocity profile calculation of the original My Jump, My Jump 2 also measures contact times, stiffness, the reactive strength index (RSI) and your leg asymmetry. The force-velocity profile calculation has been improved too: now it is easier to know which capacity should you train and, more importantly, how much could you jump if you would reach your max potential! Finally, with its renewed database, you can save and export to Excel as many jumps, FV profiles or asymmetry tests as you want. New design, new tests, same accuracy!

Is My Jump 2 an update or a new app?

My Jump 2 is a whole new app, not just an update of My Jump 1. We've been working very hard to add new test, a more intuitive design and improved features. All this would have been impossible without your support, so we are really thankful for trusting My Jump again!

Can I import my old My Jump data into My Jump 2?

My Jump 2 has a new, improved database, with better export capabilities and new variables, so it is not possible to import My Jump 1 data into My Jump 2. However, your old My Jump 1 will still be there. Also, if you want to uninstall My Jump 1 to save space, you can always export your data to Excel and save it wherever you want.

What happens with My Jump 1?

Absolutely nothing! It is still alive and working, although with much less features than My Jump 2. Don't worry, your old My Jump 1 data will still be working on My Jump 1.

Runmatic for iPhone & iPad

We know you love running, but do you know how do you run? Runmatic is the first scientifically validated app that measures your running mechanics. Available for iOS9+ devices on the Appstore.


What is Runmatic?

Designed by sport scientists & coaches of elite runners, Runmatic is the first scientifically designed app that analyzes your running technique to help you to improve your performance and prevent injuries.

Runmatic takes advance of the slowmotion recording capabilities of the latest iOS devices (iPhone5s/6/6s, iPad mini 4 and iPad Air 2) to accurately analyze your steps while running. Using scientifically validation equations, Runmatic calculates the contact-flight times, force, efficiency, frequency and even the asymmetry of your legs in a simple, accurate way.

How does it work? You just need to record 9 steps of your run with Runmatic and select the contact and take-off of each step. Runmatic will magically provide you with valuable information about your running biomechanics and will even notify you if something seems wrong.

See a simple step-by-step video-tutorial to learn how to use Runmatic.

The science behind Runmatic

Runmatic was scientifically validated using an infrared platform mounted on treadmill capable of measuring contact and flight times with high accuracy. We measured more than 100 steps running at low, medium and high speeds simultaneously with Runmatic and the instrumented treadmill, and the results were great: Runmatic is highly valid & reliable for measuring your running mechanics with scientific accuracy. Now, with Runmatic you can check your leg asymmetry, running contact times, vertical oscillation and more just using your iPhone or iPad!

Runmatic uses the equations validated in Morin et al. (2005) for its calculations.You can read the validation paper of Runmatic here


Runmatic is very helpful for my training. It let me better understand how do I run, which is critical to improve my running economy and, therefore, my performance.

Arturo Casado, 2010 European 1500 Champion

The tools often used to perform this kind of analyses are much more expensive and generally less practical for the general population. Runmatic solves this problem and allows runners to analyze and monitor their running mechanics in an easy way.

PowerLift for iPhone & iPad

What is your maximal strength? Which weight should you use in your next training session to optimize results? PowerLift is the first scientifically designed app to measure your 1-Repetition Maximum (1-RM) in the most accurate way possible. Available for iOS9+ devices on the Appstore.


Simple, accurate, powerful

Knowing your 1-RM in every single training session is essential to adjust your training intensity and get the best adaptations. However, performing an actual 1-RM test could be dangerous and fatiguing and, if performed every day, it will most likely lead to overtraining or injuries. To solve this problem, PowerLift uses scientifically validated algorithms that can estimate your 1-RM with high precision by simply recording your exercise. To do this, PowerLift uses the high-speed video recording available on most iPhone and iPad devices to measure the velocity at which you are performing the exercise, which is highly correlated with your maximal strength capabilities. This novel approach is used by sport scientists and top-level coaches thanks to advanced instrumental like linear transducers or force platforms, but now you can measure your 1-RM like a pro just with your iPhone or iPad!

PowerLift is very intuitive and easy to use: you just need to record one repetition of the desired exercise with 1 to 4 different submaximal loads and select its start and beginning in the app with its accurate frame-by-frame navigation. After that, PowerLift will show you your 1-RM!

See the demo video to watch PowerLift in action.

The science behind PowerLift

Research has shown that there is an almost perfect correlation between the external load on resistance exercises and the velocity at which the subjects can perform the movement. That is what is called the load-velocity relationship: the higher the load, the lower the movement velocity.Moreover, recent studies have shown that the velocity at which the subjects can move the 1-Repetition maximum and each submaximal percentage is very stable, meaning that the 1-RM can be estimated in a very accurate way just by measuring the velocity at which the subject performs the exercise. Also, the load-velocity relationship allows to know what %1-RM corresponds to a certain load according to the velocity at which it can be moved, something specially important to monitor the intensity of the training to optimize the adaptations. PowerLift allows you to calculate your 1-RM or estimate what %1-RM corresponds to a specific load just by measuring your individual load-velocity profile by recording a video of your lifts. Now you can measure your maximal strength capabilities every single day to adjust your intensity and optimize the results!

PowerLift uses the load-velocity relationship to estimate the 1-RM. You can read the validation paper of PowerLift here
