In this video Loek Vossen introduces flywheel training with the Kynett ONE.

Kynett ONE: bit.ly/2zwDXMM
Kynett transformed a yoyo toy into a fitness product, by fixing the axle and disks, and using the string to create movement. This way of training is called flywheel training and is used by NASA in weightlessness space.
In regular weight training, you lift a weight against gravity, and gravity will help you to lower the weight. In flywheel training on the other hand, it will cost as much concentric energy to pull the string, as it will cost eccentric energy to slow the flywheel down. Therefore, flywheel training emphasizes the eccentric movement more than regular weight training.
Training the eccentric movement is proven to be more effective in increasing strength and muscle hypertrophy. A study in 2008 shows the effect of flywheel training being twice as big on muscle size than regular weight training.

Do you think thé universal bracket and its attachment points wil be reliable enough in the time and what about the webbing strap wear ? Thanks in advance

@molabme 3 жыл бұрын

Hi! Good questions. I personally did not have any problems with the universal bracket. I feel confident this will not become a problem in time. If you however have some doubts, you could consider using the Kynett Pro with a steel universal bracket (kynett.com/en/product/bracket-set-kynett-pro-2/). I also did not experience any webbing wear. If you somehow do experience wear after years, you can easily replace it with a new one (kynett.com/en/product/webbing-25-mtr/). Hope this helps! Don't hesitate to reach out to them (info@kynett.com).

At what point do you introduce this type of exercise into your routine if you’re rehabing? Phase 2 or phase 3? Great demonstration

@molabme 3 жыл бұрын

Hi, good question! Depends on what you are rehabilitating from. Are we talking Cardiac rehabilitation? Or sport injuries? In general I find flywheel training appropriate for both very light exercise (warm up/rehabilitation) and intense exercise (overload). That is because you determine the load yourself when pulling.

@@mrhmd8308 Hi, sounds interesting! I truly believe you can use flywheel training early in sports rehab. Especially when working together with an expert physio like yourself. Maybe have a look at some of the research too :). Here's an overview: kynett.com/en/flywheel-training/reference-list/.

How do you do squats or work the legs? 🙏🏻

@molabme 3 жыл бұрын

Good question! If you position the flywheel low (close to the ground), you can use it for squats. If you like to focus on leg exercises, I'd recommend using their squat plate or squat deck (which I personally use). Here's a playlist of videos for leg exercises when having the squat deck: kzfaq.info/sun/PLMq_iPr5c7OP95yGCNyQGPt1G9s3HoZK3.

What is the kgm2 of the 4mm and 10mm disks?

@molabme 2 жыл бұрын

Good question. According to Kynett, the 4mm disks have an inertial load of 0.012 kgm2 per disc. The 10mm disks 0.029 kgm2 per disc. You can put 2 discs per device. Hope this answers your question!

How long is the rope?

@molabme 3 жыл бұрын

They have a 1,5m and 2,5m rope. The rope length adjuster is included, so you can easily shorten the rope :). Does that answer your question?

@tancreeee 3 жыл бұрын

@@molabme Yes thanks! It is possible to further adjust the rope to increased length?

@@tancreeee I'm not aware of a longer rope. I also never experienced a problem with the rope being too short. In the video I used the 1,5m rope. Would you prefer a longer rope?

@tancreeee 3 жыл бұрын

I was supposing to use the flywheel not only for analytic exercises, but also to global exercise (as direction changes) with tecnical components, so I would like a longer rope to grant wide range movement to be performed

By no means am I saying that flywheel training, or even this version/product, is not good. But for someone claiming to be trained in this area your written review has some utter nonsense in it. You seem to have missed the fact that many athletes in power based disciplines have been coached, correctly, to develop strength with low repetition, necessarily slow - though, crucially with the intention of moving the load as quickly as possible, as part of a periodised programme. This has been proven time and again to help generate power - look up some of the force curve graphs of measuring low weight, high speed, medium weight medium speed and high weight low speed training effects. To say that high load/slow movements are useless for athletes is rubbish. Within that periodised programme. Additionally, you make mention of eccentric and concentric forces being equal, when any good S&C coach knows that the eccentric loads should be greater, to match the human strength parameters. I assume you were paid or otherwise rewarded to offer this stuff? Selling a product via misinformation is not a clever move.

Hi and thank you for your feedback. I dived into the article to find the sentences that you refer to. I think we are misunderstanding each other. I’m not saying “high load/slow movements are useless for athletes”, I’m saying: being able to lift a lot of weight in the gym without being able to transfer this into power in (for example) tennis, is useless for tennis. What I mean is: being strong does not per se equal being powerful in your sport. There is another component: speed. About the eccentric/concentric part that you refer to. I again think we are misunderstanding each other. What I mean is that the energy you put in the flywheel to accelerate it (pull, concentric) equals the energy you need to decelerate the flywheel (eccentric). I’m not talking about the muscle perspective, but from Newton’s third law perspective: action equals reaction. I have another video about eccentric overload in flywheel training. In the future, I will do my best to explain myself better. The review (video & article) was my first content creation for my website, to find out if I like making something like this. It cost me money (camera operator, editor etc.) and I did not get paid for it. Therefore, reading your assumption about me getting paid and spreading misinformation only to sell is not so nice to hear. Thx again for your feedback and let me know if there is anything else.

@@molabme Okay, fair enough. To address the most important point first re compensation etc. my apologies. It just seemed that way from the information on the webpage version that looked likely to have come from the company and the hyperlinks given. I got that wrong and retract, noting though that it was posited as a question rather than a definitive accusation/complaint. The strength/load/power aspect was, then, probably a lack of explanation and a subsequent misjudgement of your position. As for eccentric loading, that is why better flywheel trainers SHOULD have some mechanism designed in that provides a ratio so that the 1:1 Newton balance between concentric and eccentric is overcome. But rare and presumably expensive.
