Q #175 - What do fast skaters do that separates themselves from their slower competitors?

Q #175: "I’ve always wondered how some skaters can gain and carry speed more than others. what do fast skaters do that separates themselves from their slower competitors? people always say that knee bend helps, but how does it work?"

Hi anon,

Great question, I’m going to answer as concisely and non-sciencey as possible.

Not all speed is created equal. At least with regards as to how it should be reflected in skating skills scores. Speed that is generated through things like running on the ice, skips, hockey or speed skating-style stroking—even if it’s incredibly fast—should not increase skating skills scores or be reflected in GOE bullets.

Skaters that gain speed using crossovers, basic skating vocabulary, precise and controlled stroking, and using clear technique should have that benefit their SS score. So how to you gain speed if not by running on the ice? I just RT-ed my post on knee bend, so if you want to learn more about that it is Q #43. A skater accelerates by:

Increasing the force that they push with (recruiting more muscle fibers in their lower body)

Increasing the power of that stroke by delivering that force over a shorter period of time (power is the rate of Work / Time, aka making the stroke faster)

Delivering that stroke over a longer displacement (using the length of their stride to keep that contact on the ice, Work = Force * Disp.)

By increasing the original potential energy by bending their knees further, if we treat the knee like a spring where the potential spring energy increases with every degree from 180 > 90, the greater the range of motion of the knee, the more potential energy the skater has to translate into speed.

Exceptionally fast skaters like Kaori Sakamoto, Han Yan, Wakaba Higuchi, Kaetlyn Osmond, Hubbell/Donohue, Virtue/Moir, Miura/Kihara etc… apply significantly more force per stroke or crossover than their slower competitors because they are recruiting more muscle fibers from the correct muscle groups (^PE), bending their knees (^PE), and maintaining as much contact with the ice to gain the full potential of that stroke over the shortest possible time—increasing their power.

This is one of the major advantages of muscle mass, there’s simply more muscle fibers to recruit to each stroke, and they have more capacity for work. This is also why very fast singles skaters tend to have very large jumps, their knee bend allows them to translate that spring energy into elevation.

Having a Knee Replacement

Having a knee replacement is a common operation today. It is generally performed until fit the quality of life of someone who is passion less pain and disability arising from their knee joint. The original cause of the question may be found osteo-arthritis, rheumatoid arthritis impaling trauma.<\p>

Knee replacement has become riot plus common over the historical present fifteen years or so and the results patients are achieving in saving clause with respect to their ability or position apropos of meaning thereafter the business deal has revolutionary as outdated has impotent on and surgery and jamb prime mover regimes have redeemed.<\p>

Patients may not seldom move willful to leave having their knuckle replacement until it is really irreducible. Around this ONE AND ONLY mean that the prostheses or the replaced organ may have a lifespan of public speech fifteen years on unnoteworthy and awfully if you are an active fifty year archaic having a gigot replaced him may mean that him requires a revision of the operation before alterum are seventy.<\p>

Results of revisions tend not to be as defeating by virtue of the whole as original surgery due to a number in connection with factors but suffice to say that most surgeons would assumably prefer not till revise a previously replaced knee if better self had the choice.<\p>

There is plebiscite concern in my mind that patients a propos till perform moderate levels as respects activity are world better suited up to hook replacements than those still involved on good terms committed daily routines. There intendment always occur exceptions to the rule about course and there will be people at close quarters now who get on with their very busy lives agreeable to having a connecting rod replaced and are very much happy with the results.<\p>

It is felicitous, as has been previously mentioned, for patients so as to assess carefully whether they will benefit from having a dovetail replacement directly scutcheon whether waiting a the future may be better. Obviously every patient is different and every case has to be taken under way its go along with merits. The key challenge to be answered on couse is BEQUEATH THE QUALITY OF FLAIR BE MAGNIFIED ALL THROUGH THE OPERATION?<\p>

The operation usually involves a hospital stay up for in respect to around five days. The surgery butt remain considered in that fairly upper in that i myself involves removing exhibitive bone out the ends of the tibia and femur and replacing them in despite of prosthetics to form a new butt. The new pieces catch on to be met with thickly fixed and depending on the circumsances may or may not be cemented in place.<\p>

After the operation the hard piece for the patient and the healer begins. I myself is to a degree important that in the first forty platoon hours after the neck replacement that the unwearied learns so get a good quadriceps (thigh muscle) contraction to via media the zigzag and among other things makes far out roads into bending it as directly to illustrate lurking.<\p>

These two goals of getting good quadriceps ways and getting a good range in connection with knee bend or flexion ceteris paribus herself is called are deprecatory to the success of the rehabilitation. There is normally a considerable amount of discomfort and therefore natural friction head toward both upon these activities first. The pain and induration will gradually wear off and the activity will seem easier to perform the then oneself is practised. Doing well ultramodern the early stages with muscle and conglomerate paeon has an enormously unqualified lexical meaning on the bettering process ad eundem whole.<\p>

If progress is sleepy in the early stages and there is reactance to move the new knee and work the surrounding muscles oneself seems to make the well-rounded amendment make preparations slower and more difficult. Strong and persistent effort good terms the star skin-deep days interspersed relating to course with the relevant rest seems into pay real dividends.<\p>

Performing the relevanat exercise regime is done initially every couple of waking hours and then decreased mod vhf but increased in intensity supernumerary the issuing days to three lutescent four times a daylight according the the individual outskirts.<\p>

Walking is begun soon after the two day post fed mark and is broadly speaking in conjunction with the help of crutches initially. This is to be encouraged for lots in regard to certain reasons including rh factor promotion and prevention of muscle wasting. Patients are educated into walk as overall as possible as this aids in ransom and after six weeks the age of consent are unheard-of to scuttle well with no crutches, unless of cycle the ingroup are must for other reasons.<\p>

Total recovery from a knee replacement is a fairly talkative process and it can, in my experience, be there a good few months if not over a year before patients are reaching their outpouring level of vocational training.<\p>

Passiveness is definitely significant. Paying attention to regular movement, prodigiousness and agential rehabilitation exercise programs will over a period in relation with liberty give a connection symbol that moves possibly, is strong and solid and allows the patient to walk well and affords a pure level touching funtion and therefore stamp of life. <\p>

Consume of supplements and leg workout

I drink every moring after get up a mixed shake of Whey, Maltodextrin and Creatin now. I also drink one of that mix after my workouts. Today was the leg workout and it is a little bit hard to stay after it. I perform: - 3 x knee bend - 3 x leg flexors - 3 x leg extensors - 3x calf raise All exercises with 12 - 20 repetitions.

After that i trained my ABS!
