Flywheel Training: Does It Actually Create Eccentric Overload?
HTML-код
- Опубликовано: 29 сен 2024
- Just because you use a flywheel device, does not mean that you will achieve an eccentric overload. Because an eccentric overload requires a greater peak eccentric force and eccentric RFD than the max concentric portions of the movement, an athlete who does not use KBox correctly will likely not achieve an overload. The KMeter does a great job of demonstrating this. After each set the coach and athlete can see these performance metrics and observe how small changes in the movmement strategy impact output.
Wtf is he going on about 🤦♂️
Gym guy trying to explain physics. Senseless.
The "Gym Guy" has a PhD in biomechanics (the study of physics applied to living organisms).
John J trying to understand physics. No idea.
Gym guy with an MS in sport science.
thanks for the great explanation of how to use this device effectively. 100% i would have messed it up, haha
You lost me, and that is likely due to my limited education. maybe do a practical application series :)
No, I got lost, too! I was an AT,C, CSCS, H/FI ; he could've simplified his explanation very easily. But, in sports and exercise science, people tend to like to use a lot of jargon because of a perceive lack of respect for the field.
If I understand correctly, if you pull up in 3 ft. of distance with a force of 40 lb. and the lower yourself to stop the inertial wheel in 2 feet of distance than you get that same 40lb of force pulling down on you for one foot of distance. Does that sound right? you have expended more force going up and you "condense" the distance that that same force has going down, so the muscles in the downward direction have to work ginst the greater force that you developed going up.
This is a good way of simplifying the concept.
can a box replace my rhino belt squat. will box will be easier on a bad knee??? have some arthritis from playing sports and rhino belt squat makes my knee sore every time I use it:(
so I was wondering the k box will be better on the knees? I bought the rhino cause I also have two bulging disk in lower back but it puts a lot of stress on knee. I am not a powerlifter but I like to keep my knees toned and if I can get some muscle with k box that will be nice too. I like rhino but I don't know If I will make the right decision selling it to get k box??
i have been using the kbox with the accelerating isokinetic machine the Jumper and the jump squat machine the supercat getting crazy results …
but why is flywheeltraining not as popular?
I would have loved it at the start if you'd said, "Yes..." and then explained all of this.
I understand what you're saying, but... What's the benefits?
Ugggg I understood nothing!😤
I have read somewhere that the basic advantage of using kbox over traditional resistance equipments is that you doesn't stop at the end of concentric phase and you quickly shifts to eccentric movement which led to increase in RFD. But you are telling to pause during the movement which is in contrast with the above. Kindly comment
he was talking about how to achieve true eccentric overload.
Flywheel training indeed has unique benefits over traditional gravity loaded training.
Flywheel training shines in strength, hypertrophy and power if done with proper intent.
If you have a greater absorption into the ground when jumping will it carry over to producing force more easily and efficiently? Or does the eccentric and concentric have to be balanced out for a better vertical results?
That's what I'm TRYING to do my masters on (with high drops, not with flywheels)... Does purely eccentric overload, which allows greater loading for a greater time (because you can slow down and stop a LOT more weight than you can concentrically lift), still confer an improvement in power or strength--as measured by vertical jump and/or squat? Currently seeking a chair and a lab, if you know anyone interested.
@ I'd say go to the gym all day. Even if a kbox can be effective for a few specific movements, the gym offers much better versatility. As a baller, you need the dynamic movement of squats, half squats, weighted jump squats, and Olympic lifts and whatever else you want to do). It's a lot easier to cheat reps on a kbox too. If you get tired, you may move slowly on a box, but 300 lbs on your back is 300 lbs. Try one out if you can find it, but I advise against buying it.
I’m lost.
The flywheel can't pull you down harder than you pull up on it. BUT, if you pull it with 200 Newtons of force upwards (concentric) for 3 feet (200/3= 67N/ft), but stop it at thigh height on the way down (200N/2ft= 100N/ft) then the eccentric phase is higher than the concentric .
basically its conservation of energy. so over the same time/distance as concentric movement you cant overload it eccentrically. just like a normal barbell.
You can create an eccentric overload if you either 1) input more force through external means (like a partner or use of hands) and / or 2) you slow / stop the wheel very abruptly.
@@AthleticLab just like a barbell
@@AthleticLab Double leg squat on concentric and single leg for eccentric is another option
@@bunny.bunbob no, a barbell will not forcibly push you down, so although there is MASS, there is no acceleration (or deceleration). This is what the kbox does, it provides a greater force on the eccentric by increasing the amount the straps underneath accelerate in the opposite (eccentric) direction. In practice, a set of 10 repetitions on the kbox with a large flywheel feels far more difficult that a set of barbell back squats for my 10RPM.

"it provides a greater force on the eccentric by increasing the amount the straps underneath accelerate in the opposite (eccentric) direction." explain this please.

Can’t you do the same things with a barbell or with bands. And what about the traditional 1-3-pause, repeats. And box jumping and time honored hurdle hops? I work with young tack athletes (1k - 3200 yds) who’s weight training rep range is between 10-30 over no more than 12 weeks in a calendar year. Not sure this equipment is valuable for middle or long distance endurance athletes when traditional training tools are so effective. Interesting concept. Like to see how this concept evolves
Bands and a barbell are very different. This can be used to easily create an eccentric overload. You can't really do this with a banded barbell.
Traditional training tools are the default just as you've suggested and we love to hear your focus on the basic fundamentals. We wish more people would do that. We tend to use this with more advanced speed-power athletes but it can also be used with any other population.
What on earth is the point of this machine when barbells and cable pulleys have been invented??
really u are asking this after whole word being stuck in quarantine? someone has limited space
@@francescocalvanese6235 point, but if you have room for this you have room for a set of dumbbells.
@@francescocalvanese6235 so if I don't have limited space this machine is not for me then?? I already have a selectorized functional trainer, a selectorized lat pull down machine, a rhino belt squat, rack and more equipment
Barbells and cables cannot do what this can do. Our gym has 70+ barbells and 4 pulley systems. We also have multiple flywheel devices. If the only tool you have is a hammer, you tend to see every problem as a nail.
Jeezuz just pick up a barbell in the amount of time the explanation takes
