  1. Well, I read through his article, but didnt look at the video. I thought what he said was absolute rubbish. The facts are confused and reversed througout. The only thing I would agree with, is that you shouldnt need to be taking fibre supplements. You should be getting your high fibre intake from fruit and vegetables. As an example of the reversed logic: e.g. "If insoluble fiber causes large stools, large stools cause straining, straining causes hemorrhoidal disease, ..." Large stools (which if they come from fibre are SOFT large stools) cause LESS straining, and so REDUCE the the chance of hemorrhoidal disease. All twaddle. I wonder how people can write this stuff. I suppose they have to write something different, to get attention and sell products. Or maybe its just a practical joke.
  2. Following a brief discussion about having the strength to hold yourself up in a straddle split, I was prompted to post this - if you cant hold yourself up, try this instead (Britains Got Talent 2019): BGT_strength_in_a_straddle.mp4
  3. One way to let go is to do what you are doing - focus on a different stimulus, so your attention is distracted from the one you want to let go of. Every time you focus on something that annoys you, you are telling yourself that it is an important stimulus. Naturally, the brain adapts to become more responsive to what is important, so the neural connections between the stimulus and your consciousness and the resulting arousal become stronger (generating the fight or flight reaction, in the extreme). If you distract yourself with another stimulus, over time the neural connections with the annoying stimulus will get weaker and maybe even eventually disappear, so you are no longer aware of it. Every time your arousal level is raised (maybe by the effort of trying to relax!) you are preparing your body for action (fight or flight again) and you will increase the importance of the annoying stimulus for you. That is why relaxing by focussing on your breathing is good, because (1) it is a distraction, distracting you away from the annoying stimulus or situation, and (2) long slow out-breaths help relaxation. As for sensitivity to sound interrupting sleep, use earplugs PLUS a noise generator in the room, to help mask outside noises (it can be white noise, or something relaxing like birdsong, depending what sort of noises you want to mask). With practice, the conscious control of your relaxation will become easier. The brain is set up for learning!
  4. What sort of explanation are you looking for? If you are looking for a description of neural mechanisms, you can search Wikipedia with terms like “attention” and follow up links to the neural mechanisms. You can also search the medical literature at https://www.ncbi.nlm.nih.gov/pubmed. However unless you have a background in neuroscience you will just end up with a list of brain structures with no way of putting them in context, which will mean further studying. Or if you are looking for an explanation from the point of view of subjective experience, then I don’t know what to say, except that for me, one stage is generating a sensory experience associated with the phenomenon I am trying to achieve, and then refining it until it becomes more precise. Reading about neural mechanisms may help illuminate the neural mechanisms involved in this. However undoubtedly there are other things going on as well. But as for making a more definitive link between the neural mechanisms and the subjective sensations, in the end there is a gap that cannot (at the moment at least) be filled: search Wikipedia with the term “the hard problem”.
  5. A friend introduced me to this nice anatomy program. It has an extensive model of the human body (at the moment only male, though they have a supplement for the female pelvis, with a full female body to come). One advantage is that it allows you to visualise all those little muscles that intertwine with other muscles in 3D, that are so awkward so see in most anatomy books. There are extensive tools for adding layers of muscles, connective tissue, nervous system, etc, at will, selecting some, fading others, etc. One especially nice thing is that in many cases the action of the muscle can be shown in a movie - as shown in this screen capture (attached). There are lots of other tools, which I've not explored. I have a single user single-platform licence (one-off fee of US$60) - there are also annual licences for student, professional, teaching use etc which allow sharing of information, access to quizzes etc. As far as I am aware, I can't share the video (which the system will save), except through their own system (needing the appropriate licences presumably), though I can do it with a screen capture There are limitations. In general, it does not show the internal anatomy of the individual structures. The central nervous system only shows as the outer layer of dura mater. An anatomy book with detailed drawings might show more detail of the muscles, giving a better idea of the organisation of the muscle fascicles within (and similarly with other structures). It is an anatomy program, and not a biomechanics program, so it only shows simple movements from a neutral position - for example, it does not show how the leg muscles act if the hip starts from a turned out position (as in ballet). Some muscles (e.g. around the rib cage) may not have a movie associated (maybe because the actions are not certain, or are too complex to program). It has allowed me to easily get insight into some points of muscle action that have been puzzling me - I have found it a very valuable program, and have only just started exploring its potential. There is a 3-day free trial. Highly recommended. 3D4Medical_Complete_Anatomy_demo_3.mp4
  6. @pogo69 Nuts are certainly nutient-dense, so are valuable for that reason (and that is why I eat them). As for being a valuable source of fibre, I'd say if you eat enough nuts to make a significant difference to your fibre intake, you will be consuming too many kJ (or calories). In other words, I DISAGREE with the oft-stated opinion that nuts (or hazelnuts at least, which are the only ones I looked at) are a valuable source of fibre. I agree that the information is all epidmiological - this is all we have to go on - which is so often the case in health studies. But while the results may be uncertain, they are still valuable (though should be taken with a pinch of salt, as always with epidemiological studies). I'd never heard about non-digestible animal parts, and their effects, and whether they can stand in for plant fibre - I need to look that up. Jim.
  7. I often heard that for straddle splits (where connective tissue can often be the limiter) very long holds are a good thing; I agree with Nathan that (theoretically at least) we expect long holds to be good for stretching connective tissue. However, in general now I avoid long holds (longer than a minute or so) if I feel a strong effect on the muscle. I have found that in this case, long holds seem to cause extra damage to the muscle which can limit flexibiity later on (but I have not dared test this to destruction). Now I can sit comfortably in forward splits I tend to do that for a longer time (5 mins) in the hope that it will become part of my normal range. Nevertheless this can lead to some sort of bruising feeling around the upper insertion of the outer hamstrings, that shorter stretches would not. More and more I am cycling in and out of the stretch, in approx 2-sec cycles, with the stretch on the out-breath. I use this both for myself and with students. This allows you to stretch further than you would if the stretch was held. I think the pain and tissue damage takes time to appear, and the cycling means you have moved out of the stretch again before this has happened. I combine this with longer held stretches (30-60 sec). It is certainly a nicer way of going further, though I am not sure of the long-term effects on increasing flexibility yet. Jim.
  8. We're hearing recently that we should eat more grains, whole-grain bread etc, to increase our fibre intake (for males, we should be getting 25 g fibre/day; some say 30 g/day). However grains are also energy-rich, so is there a danger in getting too fat if we try to increase our fibre intake from these sources. Therefore, busy bee that I am (or a retiree with time on my hands) I've been searching out the energy vs the fibre content of foods, with particular emphasis on those that are promoted as high fibre. A summary table is below, and I have attached the original xcel spreadsheet with the link to my main source, and the details of each food. If we assume that someone is getting 50% of their energy from (zero-fibre) animal protein and fat (the maximum recommended), and with a recommended intake for a sedentary male of 9900 kJ/day (2366 kcal), the we need 4850 kJ/day from other sources. The table below shows the energy intake if we eat enough of that food to get 25 g fibre/day. They are arranged in order of fibre/kJ ratio (higher numbers are more fibre for the energy content). Therefore someone eating exclusively foods from potato and below in the list (plus their animal protein and fats) will be eating too much energy, if they aim to get 25 g fibre/day (I've called this the high-energy group). Note that this is only a first approximation, as many of these plant foods contain protein and fat as well, so the proportion of animal products may be less; also people may choose to have less than their maximum recommended amount of protein and fat/day. There are a few interesting points to me: 1. Its interesting that at the top of the list are a lot of boring, traditional, vegetables, often rudely called "fart-food". 2. I have concentrated on wholemeal breads (info from the shelves of our local branch of Coles). Of these, only Lawsons Stoneground Wholemeal is well into the high-fibre list, and the other two wholemeal breads only just creep in. The "grains" breads dont. 3. Some food promoted as high fibre in fact falls into the high-energy/low-fibre group - this includes Special K and brown rice. I've included walnuts because they are often promoted as high in fibre, but their energy content/unit of fibre is massive - though I doubt if we'd eat enough of those to make much of a difference. I've included lettuce, to see what it comes out as, but I doubt if we eat enough of that either. I've omitted other foods that are promoted as high fibre (e.g. raspberries) if we're not likely to eat enough to make a difference. Orange juice is pretty much a disaster from the energy/fibre aspect. 4. I didnt include skins with potato because I dont recommend them - they accumulate the nasty chemicals that farmers and distributors spray on them. I was surprised that Coles baked beans in tomato sauce had such a high fibre/energy ratio. Obviously they've avoided adding too much gunk into the sauce. Also, dont take too much notice of small differences in numbers - there is a lot of variability in the original data from different sources. Below: high fibre group in green, high energy group in red. The attached spreadsheet also includes a copy of the table sorted by type (vegetables/grains/fruit etc).

  9. Its been a time since this was posted, and no senior teacher has responded, so I'll put my two cents worth in. What do you mean "vertebrae stuck together"? Do you mean she loses mobility in a certain part of her spinal column? This could be for many reasons. Somehow your wording suggests that the bones are locking together in some way (which would really have to be diagnosed with an x-ray or MRI), but the first thing that occurs to me is that the muscles have gone into some sort of spasm or tightening in response to the activity, stopping the vertebrae from moving. If this case I'd suggest relaxation, stretching, and loosening exercises for the back. You could try spinal twists, and lying back over a firm rubber roller, moving it along the back, and then many standard yoga back exercises, but doing only the gentle ones, and only doing them gently. Then you would need to follow it up with strengthening for the back. There are some of these exercises in the series that can be downloaded from the Stretch Therapy website. Jim.
  10. Thank you Kit for posting such a detailed commentary. I started teaching before there were many scripts available through ST: I found some basics on the web and have adapted them over time. The final relaxation of the class has 5 phases: 1. Body position, alignment, feel the floor, focus on breath etc (same wording each time, for ritual reasons). 2. Progressive relaxation (I use 4 different scripts, and cycle between them). 3. Deepening the relaxation by guided visualisation (not sure how these work for non-visual people though). I have 12 basic scripts* which I cycle between (originally found on the web and in books, plus a few I have devised myself), and adjust each one on the fly depending on how I am feeling. 4. Affirmations, in some classes. 5. Final phase of continued relaxation, followed by gradual bringing out of deep relaxation (same each time, again for ritual reasons), and a clear signal that the session is over. (* which are gradually replaced over time.) to some extent these are the techniques used in hypnosis, though I do not use the progressive levels of deepening that hypnotists use. This also avoids the problem that people might drive home still under hypnosis. I am not sure from earlier comments about how much guidance is given in breathing. One thing my yoga teacher (Ailsa Gartenstein) was very emphatic on, was not to give too much guidance of the exact timings - people prefer establish their own rhythm to your general instructions. Jim.
  11. I give classes as a stretch teacher in Australia (regular once a week group classes, plus occasional individual classes). Generally, my goal is minimal touching, to protect myself from potential accusations, no matter how misguided. Yes, we do partner stretches in class. I will demonstrate on one member and then assist the pairs in partner stretching - because this is all public and my class members are all older, around my age, everyone is very relaxed about that degree of personal contact. On the other hand, when I give individual classes at home, generally to much younger women when I am solo with them, I am very careful to not open myself to any potential accusations, no matter how misguided. I am also influenced by contortion teachers who I respect, who teach the most extreme poses with minimal touching - often just a light touch to elbow or ankle to guide alignment. There is one partner stretch that I routinely use that involves closer contact, which is the assisted lunge. I explain my policy ahead of the class, and ask permission explicilty before doing this stretch, and it is usually the only one like this. I have never detected any unhappiness with this degree of contact, but the last thing I want anyone to say is "the old man couldn't wait to get his hands all over me". By staying very well clear of any potential danger situations, I have found all my students very relaxed and confident. I am also influenced by my own experience, which is that where it is possible to arrange it mechanically, I have found it more effective to use solo stretches. This way the amount of force applied can be exactly titrated to requirements, and one is able to relax into the stretch (or maybe bracing in certain places where that is needed too, while relaxing elsewhere) more effectively - there is a closer feedback loop between the effort to apply the force and the resulting stretch sensations which I have found allows you to go into the stretch more effectively. I am in a different position from people like massage therapists and physiotherapists who have standard manipulations and a large number of professionals to back them up, so obviously my comments dont relate to those, just to someone in my situation. I just thought I'd add my views, because it is important to me, and also a matter of current discussion among contortion teachers that I know (I am not a contortion teacher by the way). Jim.
  12. I'm just wondering if the stretches that work best as partner stretches are stretches that primarily work on the fascia. In some cases it seems to me that muscle (and its reflexes) are the limitation, in other cases more the fascia. Working out which of course is difficult, and it may well vary from individual to individual. However where the critical tightness crosses multiple muscles, or does not correspond to the lines of muscles, and/or where long held stretches seem most effective, I wonder whether fascia is the primary limitation (group 1). Where the tightness corresponds to the line of a muscle, and where the CR method works well, I wonder if muscle is the primary limitation (group 2). There is of course no proof that these conjectures are true. In my experience, stretches in the first group can be more effectively helped by partner stretches. I find that partner stretches do not particularly help those in the second group. Does anyone else have views on this? I could post some examples of stretches in the two groups, and will later if requested, but have to go and stretch now!
  13. Anyone got the full-text version of the article mentioned, that they can send us?
  14. Just seen Kit's comment on dancers with or without square hips, and looked at those pictures, where there's a lot of variation. I'd point out that different schools of ballet treat the issue differently. In Russian technique, the hips are as square as possible, and lifted as little as possible on the side of the working leg. RAD (English) and Cechetti allow a small amount of lift. Balanchine technique uses a large amount of lift with the hips rotated towards the side of the working leg. It can look ugly to people trained in the other techniques - here, opening the body to the side, and the degree of extension of the leg (in the sense of lift), are primary.
  15. Put your hands on your hip bones. They will show you if the hips are level sideways and square to the front.
