dann2707 Posted August 31, 2011 Report Share Posted August 31, 2011 I have developed some kind of weird slipping feeling after doing shoulders the other day. it feels like something moving up and down on my bacj at the tip to the left likr attached to my shoulders. I especially felt it when doing barbell shrugs. It doesnt hurt at all but its just weird sometimes when i move my left arm up and down i feel it. any ideas what it is? and no its not the beast from richard laymans book 'flesh'. well i hope not anyway On this pic at the top just below his neck there are weird sticking out bits, its where the left one is. http://www.buzzle.com/img/articleImages/552246-10310-54.jpg Quote Link to comment Share on other sites More sharing options...
MonsieurMonkey Posted August 31, 2011 Report Share Posted August 31, 2011 Your shoulder blade being slightly double jointed maybe? No idea if it's possible, but I don't know what else could be slipping. Quote Link to comment Share on other sites More sharing options...
Krisboats Posted August 31, 2011 Report Share Posted August 31, 2011 Different types of muscle fibres, but I can't remember which is which. Type I: (slow twitch) Normally activated at 0-60% maximum strength output. Endurance. Think typical long distance runner build. Smallest of the muscle fibres muscle fibres. These have very little force output capability and very little growth potential. Type IIb (fast twitch) Activated at 60-85% maximum output Largest muscle fibers that cause the largest amount of muscle growth and most amount of force. They are capable of massive force output but fatique quickly. Sprinters, powerlifters and bodybuilders would have a large number of these fibers. Type IIa Activated at 20-75% of maximum ouput A mix of type I and type II. These fibres are kind of a "best of both" situation in that they are capable of a high force output and are very fatigue resistant. They have the ability to shift between type I and type IIb fibres depending on how they are being stimulated. They are typicall stimulated during high intensity aerobic activites like sprinting or, rather more apropriately for us lot, trials riding. An average person will have an almost equal number of each fiber type in their body. It's still not known for sure whether you can change a fiber from one type to another but current research suggests you can only change the characteristics of a particular fiber. On this pic at the top just below his neck there are weird sticking out bits, its where the left one is. http://www.buzzle.com/img/articleImages/552246-10310-54.jpg Weird sticking out bits are called the trapezius group or "traps". These are the muscles most exerted when doing your barbell shrugs. Is the moving body part moving by itself or does it move when you poke it? Muscles that are unused to stimulation sometimes spasm a short while afterwards and in doing so will involuntarily contract and relax. It could be this if your not used to doing this particular excercise or if you haven't done it in a while. It could also be that after excercising you've made your nervous system more aware as weight training improves your "mind-muscle" connections. You could be adjusting to something you've never really been aware of before. Or thirdly, you could be a freak and have random muscles walking around under your skin.

JD™ Posted August 31, 2011 Report Share Posted August 31, 2011 I've never understood people worrying about nutrition for such short runs unless they're trying to win or achieve a PB - both of which cases you're saying you're not up for. Just do what you always do before a run, don't shock your body with anything different on 'race' day because it's the worst thing you can do. Add another 15k and we'll talk nutrition Quote Link to comment Share on other sites More sharing options...
shamus Posted August 31, 2011 Report Share Posted August 31, 2011 psychological benifits?? If you have a poor diet normally it'd help surely? Mme- I've got the Eden half coming up in October, but want to work on bike fitness and general strength/bulk, is this possible while building back up to half distance? Curreently only cover about 15 miles a week in approx 6 mile to 8milers but all XC on steep terrain. But add about 15-20miles XC cycling per week and weights/core work after running sessions. I'm loading on recovery shakes and protein shakes around exercise but not sure the proper proceedure (I understand its protein 20min before and recovery within 20min after?) whilst still eating a balanced diet and increasing calorie intake by about 20%. I'm also forcing more sleep into my daily routine. Anything else I should watch out for? Quote Link to comment Share on other sites More sharing options...
