Last night I went to the second mini-med school lecture, on muscle tone and the physiology of exercise. Both of the speakers were quite engaging, interacting more with the people there than most of the others I've seen.
The moderator was Dr. Edward Phillips. He decided to show some slides before the other speakers, showing some of the people from that body exhibit that had been at the science museum. It was interesting, yet disturbing, which is why I hadn't gone to the exhibit when it was in town; I wasn't sure whether I'd be squicked or not. Those were human beings, not plastic models, and even though they volunteered, it's a bit uncomfortable.
The first speaker was Dr. Richard Schwartzstein. He discussed what muscles are made of (protein, glycogen, and water), and the distinction between fast twitch (sprint, high intensity, anaerobic, etc) and slow twitch (endurance, slow to fatigue, aerobic) movement, describing how acid build up comes more from fast twitch. He had a slide of the Fick Principle, showing the circulation around heart, lungs, and muscles. For the vast majority of people, the lungs are not the limiting factor, but the heart and/or other muscles. Exercise teaches the heart to pump more efficiently, increase the capillaries in the muscles, increase the oxygen to the muscles, as well as the ability to use that oxygen. With age, the heart's stroke volume is maintained, but the maximal heart rate declines, and the ability to generate new protein decreases. The lungs also decrease in function, but that doesn't affect exercise because of the levels of reserve (unless there's something else going on, of course). He touched on the importance of flexibility, at least as much as strength, because it is a key factor in avoiding injuries.
The second speaker was Dr. Jonathan Bean. He talked about physiatry, and about the difference between movements that shorten the muscles (and should be done slowly to maximize power) and those that lengthen the muscles (and should be done faster). There was a lot about exercise as we age, which was unsurprisingly all about the benefits of exercise at any age. Interestingly, it seems that most stooping of older people isn't about the bones of the spine, but about the muscles of the back atrophying faster than those in front, and that asymmetry brings on stooping. He also talked about one measurement of strength being the 1RM, one rep maximum, and how the greatest force is usually at about 70% of that.
Two things from the question and answer session:
- Yoga can be about strength and flexibility both, depending on what sort and how it's done.
- If exercise were a pill, it would be a best-seller, and everyone would be getting it. It helps strength, flexibility, sleep, focus, mental acuity, etc. I don't know why this clicked in my brain so well, but it did.
There was a packet of articles and exercises, too. I haven't finished reading them yet.
This noontime's Middays at the Meeting House was about the Saturday Night Girls of the North End (later, out in the far reaches of the city... Brighton, which was an hour and a half away by trolley), with a focus on one of them, Sara Galner. Sara was a Jewish immigrant from Galitzia, arriving in 1901 at the age of 6 with others in her family. She lived at 93 Salem Street, in the North End, which was called the "foreign district." The biggest groups were Italians and Jews (mostly Russians and Galitzianers). The Jews mostly lived in a three-block area, crammed into tenements: there were 70,000 Jews there. Sara went to elementary school, then to the North Bennet Street Industrial School, which is where the Saturday Evening Girls had started, grown out of a reading group set up by a woman who wanted the girls to read great literature rather than fluff. That grew to be a group that included reading, dancing, lectures, art, etc., as part of their mission, and was so popular that there were different groups just about every day of the week. Helen Osbourne Storrow became a benefactor to the group, arranging, among other things, summer camp out in Gloucester ($5/week, 2 weeks maximum for each girl). Even at this price, many girls couldn't afford camp, and there was a decision to start a business to raise money so more girls could go. Edith Brown and (someone else) decided on a pottery, setting up shop in the North End. It was called the Paul Revere Pottery, partly due to its proximity to Paul Revere's house, and partly as a way of getting more publicity for that house, which soon afterward became a National Historic Site. The pottery had an Arts and Crafts aesthetic, with each region bordered in black. At first, it was plain glazes. Over time, they changed to a wax and (er, something that's black) mixture to border each region, holding the glaze in place, allowing for thicker glaze, more intense color. Later still, the girls incised the borders into the pieces, allowing for even greater delineation.
Sara left school at 14, as allowed by law, despite her teachers' wanting her to go on. Her family needed her income. She worked in a shop, though the pottery people wanted her to work for them. Eventually they caved and matched her wages ($7/week), and accepted her demand that all the others get that rate too. She worked for the pottery from 1911 to 1921, both in the North End and Brighton locations, decorating pottery (each piece is initialed and dated). She also worked in the shop on Boylston Street, and, later, was sent to Washington DC to work in a new shop the pottery opened there (briefly staying with the Secretary of War, a friend of Helen Osbourne Storrow). In 1921 she married, and stopped work.
So much is known about her in particular because her son started collecting her work after her death. His collection will become part of the MFA. There was an exhibit there last year, and there was some mention of a virtual tour available, but I haven't found that yet.
And wholly off topic: I notice that LJ has instituted a new golden lock icon for filtered rather than just friends-locked posts.
