ACES - Ariel Computerized Exercise System

Computer controlled machines for exercise diagnostics and rehabilitation.

Athletic training of the past has been unable to reproduce real athletic movement at speeds comparable to those achieved during competition sports. ACES' revolutionary mix of computer-controlled resistance technology, custom-designed equipment and professional expertise has changed athletic training forever  .

ACES trains muscles to contract fast. The faster the muscles contract, the faster the limb moves, the faster the limb moves, the faster a person can run, the higher a person can jump, the harder they can hit, the further they can throw. The better they can functionally perform ... - Dr. Gideon Ariel, Ph.D.

Hello from Brockport!
mailed-by brockport.edu

Hi Gideon,

I hope this email finds you well.  I thought I would touch base with to update you on our progress in the Biomechanics Lab.  And, I wanted to ask you a couple of questions.

We are currently power training more than 50 athletes in over 29 weekly training sessions on the ACES in the lab from the hockey, volleyball, swim, and track teams!  Each team has their own selected exercises, which are coordinated with our strength and conditioning coaches and their team coaches.  For example, hockey and track trains specifically for sprint speed; volleyball trains for vertical jump; and swimmers train for their individual strokes.  We have created several exercises designed to mimic the movement and velocity patterns seen for selected sport-specific skills.  And we use video analysis to examine individual patterns of movement.

Our assessments include speed sets on the ACES to measure maximal velocity on each exercise.  In addition, we perform force-velocity profiles using speeds of 10, 40, 70, 100, 130, and 160 degrees per second (we have never recorded a speed greater than 155 deg/s on any exercise with the ACES).  Finally, we always have a "real-world" assessment, such as sprint times on the ice, in the pool, or on the track; and vertical jump and long jump.

Using data from our speed sets, each individual athlete trains at a velocity determined by their own capabilities, and over a range of motion specific to their body structure.  To set velocity-based intensities for each exercise, we have been using 50% (and less) of max for off-season conditioning, 75% of max for pre-season, and 100% of max for in-season.  These values are analogous to traditional load-based training, but are relatively arbitrary since there is no specific literature to guide us.

Range of motion on the ACES is standardized by determining desired starting and ending positions (i.e., physiological range of motion) of selected joints for each exercise.  In addition, range of motion is adjusted during early training sessions to maximize and the potential load range.  We have been modifying range of motion using the position-time graphs, and this has been very effective.

As you probably know, the Philadelphia Flyers now have an ACES, and they have begun to train their players.  Myself and one of my students visited their training facility when the ACES arrived, and we discussed the things we do in our lab, and trained them to perform similar measures.  Now that they have cut to their final roster, they have indicated they will send me their data, and we will share our results with them.  Their head trainer is Jimmy McCrossin, and he appears to be genuinely interested in the science behind multi-joint isokinetic training.  So I am  (obviously) hopeful that this relationship will continue to grow.

I am currently finishing papers on our training of the volleyball and hockey teams from the spring, and a case-study on a swimmer from spring-summer.  I also have an extensive set of notes for a review paper of multi-joint isokinetic training.  As you know, there is little literature out there, except for perhaps the articles from Weiss.  However, almost none of that is actual training studies.

Take care of yourself, and we'll talk soon.

Hi Gideon,

I hope all is well with you and Ann, and I wanted to extend a delayed welcome back from your trip. I hope you didn’t cause any “trouble”.

As you know, the ACES Multifunction Machine is here at Brockport, and its running very well. There has been a lot of excitement generated here since its arrival. I have been promoting the cutting-edge technology to my colleagues, students, and athletes, and have explained how the Multifunction Machine allows for methods of training that cannot be done with any other machine. In addition to me using the machine almost every day, I have several students using the machine for a variety of projects.

For example, I have a thesis student who is using the ACES machine in a study designed to investigate the effect of training on the elastic properties of tendons (a topic related to my own dissertation). The training protocol will be plyometric in nature – in fact, I’ve named it a “variable-velocity isokinetic plyometric training program!” I’m using this as a launching pad to examine the effectiveness of various training programs, particularly variable-velocity programs, on muscle power over a long-term timeline.

I have another student who is using the machine to examine EMG patterns during a straight-leg deadlift for flexible and non-flexible individuals. As part of our preparation, we are building a box-platform that will house two AMTI force platforms, on which participants will stand. When the box is completed, we will be able to measure individual ground reaction forces from each foot during deadlifts, squats, and anything else we can think of. Using the ground reaction force data and the force and power data from the ACES machine, I expect to be able to look at the transfer of force along the entire kinematic chain. I’m not exactly sure what to expect, but it sounds like fun!

I have organized a research-team of 7 exercise physiology students to begin to train Brockport athletes on the ACES machine next spring. In coordination with team coaches and our strength and conditioning coaches, we intend to train selected athletes from track, volleyball, football, wrestling, and hockey. I asked each coach to identify athletes based on their enthusiasm for their sport and their goals to pursue higher levels of competition, so we should have a highly motivated group. The research-team will initially be introduced to concepts related to force-velocity-power relationships, isokinetic training, and (variable) velocity patterns of sport-specific skills. Athletes will schedule training sessions in the Biomechanics Lab, where team members will administer a user/sport-specific training protocol. Toward the end of the semester, the research-team will measure and discuss pre-post results, with a goal to submit results for publication.

At this time, I am looking for any standardized protocols to measure muscle power, which I intend to include as a pre-post measure. In addition, I am looking for any sport-specific training protocols that I may be able to use, and in which I may be able to integrate the variable velocity capabilities of the ACES machine. I have reviewed many articles to date, but I would certainly welcome any thoughts or suggestions you may have. I did look for articles related to volleyball training, including on the APAS website, but was unable to find any detailed training protocols. If you would be willing to share some of the training procedures or stories you have with the Olympic volleyball team, it would much appreciated.

I am hoping to maintain a team of students to continue training our athletes every semester for the foreseeable future, so I will continue to expand my range of sports and athletes included in the program. My next targets are athletes and companies outside of Brockport, with which I have had some preliminary conversations. At the moment, my only concern is being able to accommodate the number of students and athletes that have expressed an interest!

Arti has suggested to me that you may be interested in coming to Brockport to speak about your experiences and the ACES machine. Please consider this an open invitation. Although it may be difficult for the college to pay you for your visit, I have already secured travel and room-and-board expenses in anticipation of the possibility.

Well, I know this email is rather long, but I thought I’d update you on the ACES machine here at Brockport. It has generated a lot of excitement. Also, I wanted to thank you again for your hospitality over the summer. Whenever possible, I put my colleagues through the same speed pyramid set (20 reps) that you had me try!

Please send my regards to Ann. Take care,
