    One thing I think you could cover is running uphill and downhill, because your running mechanics are mainly on flat ground. Hope to understand if there’s anything we should take note of.

    First of all, I would like to thank you for the wealth of knowledge that is shared on this channel, great job!
    Here are some questions:
    1. how important in your opinion is the balance between your left and right foot ground contact time (GCT) ? What could be the main cause of disbalance and how to fix it ?
    2. ankle extension during take off, good or bad ?
    3. gluts activation during run, how to do it right ? How important is to have an active gluts in general ?

  • @honza1859
    @honza1859 11 месяцев назад +1

    Hello, I have several questions.
    1) How long should the foot stay on the ground before pushoff? Should I try to get my foot away from the ground as fast as possible? But then the push off will not be so strong and steps will be too short and the cadence will be too high... Another extreme is to let my foot go backward as much as I can to produce big power with each step - this will lead to low cadence (but not necessarilly oversriding) but also to higher fatigue beacause of using too much power.
    So the truth is somewhere in the middle. But being in the middle - should I try to use more power or quicker pushoff? Ie how far back should the stance leg go?
    2) What leg (+glutes) muscles/tendons should work when the foot is on the ground? Should it mainly be glutes or should it mainly be ankles/achilles tendon? I know that both is true and the most of the body work is unconscious but anyway - should I concentrate on specific muscle/tendon to work properly? Or maybe nothing is true and the power will comme from the swing leg and its momentum...?
    3) How to achieve lower vertical oscilation (VO)? Some VO is of course needed but I am quite sure that I have too high VO. Should I eg try to use my ankles less? How to pushoff in the "correct" direction - not too much up and more forward?
    4) To achive correct technique - is it better to run on the flat or on a slight uphill (how much % of slope?)? Hills will build strength but flat track will produce speed and longer stride - with higher range of leg motions.
    Thank you for reading these questions.

    Congratulations for reaching one million views in one video! 🙂👍Here are my questions: How important is it for a runner to train at a specific heart rate?

Is it possible to train both (good running form with a good heart rate) at the same time?

    Question:
    Regarding running downhill: isn't it better to relax while handling the speed and impact increase other than braking which (over)loads the knee?
    I personally feel and do way better just letting the speed increase with attentive control. However, I haven't done it in a long descent because I'm not sure if my body can handle it in terms of resisting the impact of stacked gravity and fueling (breathing, lactate, etc.). I'm not very experienced either. When I braked while running downhill, my knees hurt at an alerting level.

    First of all, big THANK YOU! Purchasing and learning through your training course is one of my best money & time running journey investments done so far! ....and it is a lot of fun! My question is related to the body type and how to adjust the technique in order to optimize running efficiency with particular body type in mind. Just to give you an example,, in my case (52yrs, 172cm/78kg) that specificity means strong frame built with short body and legs with bulky calfs and thighs (sort of heritage from my strength fitness training decades ago:-). Moving from my minimalist running experiment and from quick stepper shuffle (which was great to start with when I lost 20 kg) to eco sprinter utilizing more dynamic and springy motions makes magic for me (thanks again!) especially on trails with moderate longer climbs...well, actually in every situation when I think about it:-) so I believe you can share more on that topic with us.

    Mr. Zillen
    Good day :)
    Regarding your recent video on cadence
    I'm a heavier runner, I weigh 100 KGs. I pick up frequent injuries when running at a faster pace, I currently run about 15 to 20k per week, but I'm trying to up that to 50k per week until spring. A coach told me that I have to higher my cadence if it was under 160. I currently average about 155 cadence on a random long run of 10-12k. So I went to the track and tried to up my cadence to 170, within seconds my heart rate was in zone 5! Later that day you uploaded that video about higher cadence. I have been a long time subscriber btw, I went back to the track, tried to fix my technique, still couldn't keep it at 170 even. I had to sprint! Best I can do is 160, what is your remedy? I cant handle another soft tissue injury.
    On a side note, I really enjoy the introductions to the videos, I find you very funny.
    Thank you so much

I have had success with your tips to get to a comfortable 170, 10 min/mile - primarily listing to songs with 170 bpm and setting my cadence at 170 running in place... then start moving.

    @Fredrik Zillen Is there any technique tips one can do to lessen foot strike impact on an injured knee? I have seen suggestions that one should not try to lessen the impact by forefoot landing. True or false? I switched from forefoot strike to midfoot last winter. Chondomalacia patella forced me to use maximalist shoes only initially on a softish soccer field. Even for 6.45+ min/km 1 km jog at the beginning of my return to jogging. Later I was able to use Novablast 2 for 1 km on the soccer field after rehab. I have seen measurements that suggest less than maximalist soles having less impact than maximalist shoes. True or false I don't know, but initially even walking on asphalt hurt with hard soled stability shoe Mizuno Wave Inspire 17. Fast walking with Novablast 2 was barely tolerable. Thoughts about saving my knee and getting more distance? I have gotten to 2 km so far on the soccer field. I have increased distance slowly cycled instead of ran during the summer.

    Q: You mentioned that a lower cadence leads to increased vertical movement, which consumes more energy. However, if you elevate your cadence while maintaining the same pace, you'll experience reduced vertical movement per step but more steps per distance. In theory, this should result in total vertical movement and energy consumption over a given distance being approximately equal. Could you provide some insights on this?

To me having stiff ankles which I cannot flex seems a bit different to having strong ankles (which I can also flex) :-). One can also ask more generally (or ask a seond question). Is being too flexible in some parts of body bad for running technique? Is there some line we should not cross? Definitely, a gray area :-).

      Wrong shoes, rotate your shoes, change them every six months or so, when you do long runs go with zero drop shoes, train your shins at the gym with shin raises and calf raises. You should see muscly shins. See also how you land, for slow runs, roll your feet from heel to toe if you normally land mid foot. Food: when you go slow, you don't need many carbs, when you train hard eat carbs the night before. Inflammation is an issue. Also, do not increase your mileage or training more than 5% every month or so. Look also into the right vitamin intake or vitamin deficiencies, you'd be surprised, use a massage gun as well and so forth and so on...

  • @successfulstone
    @successfulstone 11 месяцев назад

    I have many questions!
    Is a quiet foot strike better at reducing injuries? Or is a louder foot strike just showing that you have more force and are running "faster"? This assumes the same shoe. Different shoes are differently loud I suppose.
    As I slow down to run easy, my gait seems to be less efficient. How do you run easy and still practice that good technique? What are the most important things to keep when you slow down the speed?
    Are breathing patterns overrated or underrated for running? There's a lot of chatter online about how to breathe (e.g. 2 inhale, 1 exhale)

    I have been doing Maffetone training for about 9 months, and my pace improved from 10:30 per km, to about 9:20 per km now (which is still SLOW). I'll make the excuse that the 32 deg C heat here in Singapore is making it really hard to keep my HR low (43 years old = 137bpm).
    My wife said though, since doing this slow jogging, my running form has changed to one that's more like race-walking or shuffling (at a low cadence of 145-150, heel or mid-foot landing), and she said I should ditch MAF and go back to regular running (cadence 175-180, fore-foot landing).

      In my opinion, if you 'run' slowly then all you will get good at is running slowly. It's terrible for running form. You'd be better off cycling to build aerobic fitness, and when you run, run faster! Others will disagree, but only because they've been watching too many RUclips 'experts' who have taken the training techniques of marathon runners and tried to apply it to people who only ever run 5k.

      Why should neutral runners use stable neutral/guidance shoes? Pronation is an important part of your running, both as a shock absorber and to get better power in your push-off (as long as it's not too much). Taking it away is likely to increase the risk of injury and/or make you run less efficiently.

    not sure how to phrase? what about dealing with the bodies natural asymmetries? most ppl seem to have mild scoliosis, like below 10% scoliosis isnt officially diagnosed but exists. my mechanical neuropathy is getting worse and worse. apparently my spine is turning into a nerve grinder. may have to do with diet or leukemia, dont know if its due to calcification or lack of mass. but i must experiment with posture to minimize damage. i learned that i have left aic pattern, which involves a mild form of scoliosis. sleeping causes the worst damage, as relaxation seems to dislocate the nerve grinders sharp pits. i have not noticed running making it worse. but perhaps you can't even sense damage when you are in this state of mind and metabolism. my left AIC is like riding a skateboard in goofy foot stance (right foot in front). its like being frozen in the position of taking a step forward with the right foot. when i do the opposite movement, my body does not support it as well. even transitioning to the next step. hip tilt may be wrong. the right femur is often sore, it may break one day. i speculate its frozen in external rotation while the left one is frozen in internal rotation (pelvis is twisted to follow the frozen right foot forward step, even the sacral joint may be twisted not sure).

    There’s plenty of people saying how to increase cadence but I have a cadence of 190-200, so is there any benefit in reducing cadence, and if so how would you go about it?

      FINALLY someone who doesn't ask about how to increase their cadence. Can you have too high a cadence? If so, how do you reduce it in a good way? And those are the questions that I will address in a video with questions from you viewers.
