What is isoinertial exercise and how does it work?
Isoinertial exercises strengthen both the muscle being targeted as well as the synergistic (helper) muscles as well. This type of exercise also helps to strengthen ligaments and tendons throughout the range of motion. Isoinertial exercises are not to be confused with (although hard not to) isotonic exercises.
What is the isoinertial method?
In the isoinertial method the resistance is adapted in every moment and is proportional to the force developed in the sense that the greater the force expressed by the subject in the concentric phase, the greater will be the acceleration with which the flywheel reacts.
Is isoinertia a good form of strength training?
However the isoinertia exercises and equipment that contain constant mass was designed for use during space travel (Berk H.E. et al. 1996), this form of strength training is increasingly used in healthy (ABERNETHY, P.J. et al. 1996) and paraplegic populations (Jacobs, P.L. et al. 2002, Jacobs, P.L. et al. 2001, Nash, M.S et al. 2002).
What is an example of an Isoinertial exercise?
This range of motion can change direction but the force on the extremity doesn't change. An example of this is the yo-yo, it changes direction at the bottom, but the mass of the yo-yo stays the same. Isoinertial exercises strengthen both the muscle being targeted as well as the synergistic (helper) muscles as well.
What is an Isoinertial muscle contraction?
Shortening and increased tension in a muscle against a constant load or resistance.
What is Isoinertial eccentric?
The eccentric overload provided by the isoinertial device may be applied directly to specific technical elements, such as COD and shooting movements, allowing the athlete to transfer the external variable overload effects to the real team sport performance.
What is flywheel training?
Flywheel training is a strength training modality offering the possibility of performing exercises with eccentric overload and variable resistance that therefore differs from conventional gravity-based resistance training.
What is Isoinertial testing?
Abstract. Previous research has found isoinertial strength testing to be superior to isometric and isokinetic strength testing for prediction of task performance. The purpose of this study was to investigate tests on an isoinertial lifting machine (ILM) and their ability to predict performance on actual lifting tasks.
Is swimming isokinetic exercise?
Outside of a gym or physical rehabilitation setting, isokinetic contractions are rare. The closest example may be swimming the breaststroke in which water provides constant resistance to the movement of your arms.
What is isokinetic strength?
Isokinetic strength is the force generated by a mus- cle against resistance at a constant rate of movement (American College of Sports Medicine 1995; Adams 1998). Isokinetic strength of the lower extremities can be tested for knee extension and knee flexion.
What are the 4 types of muscle contractions?
Key TermsIsometric: A muscular contraction in which the length of the muscle does not change.isotonic: A muscular contraction in which the length of the muscle changes.eccentric: An isotonic contraction where the muscle lengthens.concentric: An isotonic contraction where the muscle shortens.
What are the 3 types of muscular contractions?
1 Types of Contractions. There are three types of muscle contraction: concentric, isometric, and eccentric. Labeling eccentric contraction as “contraction” may be a little misleading, since the length of the sarcomere increases during this type of contraction.
Are flywheel trainers worth it?
Flywheel training offers many advantages over traditional strength training. The resistance is variable and unlimited. Eccentric overload can easily be achieved as well as mobility, ergonomy and economy.
Is flywheel training good?
The performed exercises result in improvements of strength and power, hypertrophy, muscle activation, muscle length, and tendon stiffness. Other positive effects of flywheel training are athletically relevant improvements in things such as speed, jump height and change of direction.
Is flywheel training better?
Flywheel training with eccentric overload is consistently shown to be superior to traditional weights for increasing muscle power, strength, hypertrophy, and athletic performance.
The Spectrum of Techniques
While we wanted to show incremental progressions of flywheel techniques, we realize no continuum is perfect. Ideally, each method moves in a linear fashion, so coaches can safely ramp up the demand on their athletes. The science of strength and conditioning is far from perfect, so there’s enough art left to give coaches plenty to play with.
Supplemental Ancillary Training
If you’re new to flywheel training and don’t want to take a leap of faith, this method is perfect. Take any basic secondary exercise, which is usually placed at the end of workouts because they’re important enough to include but not a priority, and use a flywheel option.
Conventional Replacements for Main Exercises
In many circumstances, the next logical step is to swap primary barbell or machine exercises with the flywheel options. Depending on the athlete’s recovery ability and the program as a whole, coaches can swap out one day, one week, or one phase entirely and use flywheels.
Isometric Enhancement Techniques
There are two significant challenges with isometric work in team or group settings:
Ultra-High-Speed Flywheel Training
The highest velocity bouts on a flywheel require a little skill and experience, and decent athletes can grasp adding the extra spin after a few sessions.
Potentiation Techniques
Potentiation is a lot trickier than social media would have us believe. If you’ve done it for some time and used measurement tools, you know that nothing works for everyone and everything works for some people.
Contrast and Complex Training
Following a potentiation section, one might be fully aware of how to use contrast or complex training, and I’ll spare you the repetitive explanation. Contrast and complex methods with the flywheel don’t need to be complicated.

Sebastian Möck I think Sebastian is on point. The length change of the entire muscle-tendon unit is not and indicator of eccentric behaviour of the muscle fibers due to things like architectural gearing ratio.

Overview
Isoinertial denotes a type of resistance used in exercise training which maintains a constant inertia throughout the range of motion, facilitating a constant resistance and maximal muscle force in every angle.
The term isoinertial derives from the words iso (same) and inertial (resistance), which in one terminology describes the primary concept of the isoinertial system, or expressing the same iner…
The Origins
Since the late eighties, during long-duration space travel, was placed as a problem as the ability to maintain power the muscles of astronauts engaged in missions, given that the absence of gravity led to an environment in which they experienced atrophy of the musculoskeletal system, no longer called to support the load of the body weight, as well as a reduction in bone mineral density. Studies and research carried out about a solution that led to the strengthening of muscles of astr…
The Isoinertial Method
The isoinertial's muscle activity follows the muscular action of the sporting gesture or rather what the body or parts of it are in duty to perform in sports, according to which, in strength and speed variable, an inertial load (such as a ball), a limb or the body itself (such as when accelerating or changing direction) the athlete is forced to respond at the level coordinative motor and neuromuscular very quickly to situations and motor gestures sudden and not predetermined.
The Benefits
The great utility of the isoinertial method and at the same time what makes it different from the normal isotonic muscle movement lies in the fact that the action isotonic developed in conventional exercises (strength machines and free weights), the resistance is constant throughout the whole of movement in both the concentric phase in which the eccentric, which is equivalent to the set load. In the isoinertial method the resistance is adapted in every moment a…
