See Rating of perceived exertion as a predictor of the duration of exercise that remains until exhaustion - Noakes Br J Sports Med 2008;42:623-624?<br /><br />Hence this has significance in measuring training load as doing one 20 min threshold session followed by recovery for 30mins may give a moderate RPE whereas doing 3 x 20 min TH sessions may lead to a much higher RPE. The only difference in the session is the duration.<br /><br />alanBullyboyhttps://www.blogger.com/profile/09753503750677705017noreply@blogger.comtag:blogger.com,1999:blog-7110892371762650434.post-28899867284294559072016-01-19T08:59:14.471-08:002016-01-19T08:59:14.471-08:00Good post - very interesting.
I would like to ask...Good post - very interesting. <br />I would like to ask about the use of the training monotony (TM) calculation - is this a specific figure your looking for or is it more from a trend analysis perspective. I.E. If you do the same amount of training and the same workouts each week then TM does not change, but also SD will be closer to 0 and hence monotony will be a much higher value.<br />Also the strain calculation - what exactly is it telling you? If the monotony is high and the training load is high then we get a high strain score. How would you define strain? I will take a look - could you tell me is the article by foster 1998 this one - Monitoring training in athletes with reference to overtraining syndrome?<br /><br />thanksBullyboyhttps://www.blogger.com/profile/09753503750677705017noreply@blogger.comtag:blogger.com,1999:blog-7110892371762650434.post-48111550164082186642015-12-14T01:44:36.974-08:002015-12-14T01:44:36.974-08:00Oh what a surprise!

One paper that is a worthy read within this discussion is "Why is countermovement jump height greater than squat jump height?" by Bobbert, Gerritsen, Litjens. & Soest. Dr. Cardinale, I have no doubt you are familiar with it, but I'm sure other readers would enjoy the further discussion.

For many Practitioners using the term “Glutes not Firing” is not meant in the literal sense but simply to state that the Glutes are not functioning optimally and that a given athlete would benefit from improvement in Glute strength/activation. Most are not ignorant enough to try to claim that the Glutes are not firing at all, as we know this to be bogus. <br /><br /> I thought this may also be of interest to the post…….A recent systematic review (Barton et al. 2012) found moderate to strong evidence indicating delayed and shorter periods of activation in the gluteus medius during stair negotiation in PFPS (Patellofemoral pain syndrome) sufferers. It is theorised that this delayed and shorter activation period results in a lack of hip control in the frontal and transverse planes leading to increased stress on the PFJ (HPatellofemoral Joint) and subsequent PFPS. Whether or not impaired Glute function is a result of PFPS or PFPS leads to impaired glute function is debatable. I agree therefore that a full screening is needed for a more evidence based practice. A Good starting point could be the measurement of Gluteal strength. Prins and Wurff (2009) found reductions in abduction, external rotation and extension of the leg suffering from PFPS. <br /><br />References <br />http://ajp.physiotherapy.asn.au/AJP/55-1/AustJPhysiotherv55i1Prins.pdf<br />http://www.ncbi.nlm.nih.gov/pubmed/22945929BEZAhttps://www.blogger.com/profile/05761044108802813618noreply@blogger.comtag:blogger.com,1999:blog-7110892371762650434.post-86074658347474198532013-09-21T10:21:48.387-07:002013-09-21T10:21:48.387-07:00I agree with Darren with regards to the debate bei...I agree with Darren with regards to the debate being partially about semantics.

Almost like having to go back to the bible to look up a meaningful verse. Are we really not supposed to eat shellfish? SINNERS!<br />In your post, you make several assumptions. 1. Perhaps the terminology that is used is inadequate. Maybe it should be the glutes are not firing in an appropriate sequencing pattern as you suggest. I agree with that.<br />2.' "your gluts are not firing" is not matched by electromyographic measurements ': This question has been answered by a recent study http://www.ncbi.nlm.nih.gov/pubmed/22877831 and http://www.ncbi.nlm.nih.gov/pubmed/10638873<br />I used "gluteus maximus low back pain"<br />3. It may not be practical to screen all athletes with an EMG and movement screening tests can provide valuable information. As you indicated, how can you best determine the baseline running test is optimal. The athlete may currently be pain free but that does not mean they are working most efficiently or with an ideal pattern. Many high level athletes will be working outside a "normal" pattern anyway because of their sport. If you can break out individual movement patterns, you can get a better sense of what each component is adding to the motion. A trained eye is able to pick out these flaws in a running athlete. Isolation tests can confirm these findings and train the clinician/coach to see them in a regular movement pattern.<br />4. EMG activity with movement was greater that MVC: http://www.ncbi.nlm.nih.gov/pubmed/23312068<br />5. ' Hip motion is in fact affected also by foot placement and knee control. So, an abnormal hip pattern might have nothing to do with activation patterns of gluteal muscles' : Absolutely agree with this statement. Gluteals are just a part of the equation. A full examination of the movement pattern is in order. The gluteals appear to be weak but is it because the muscle itself is weak or the neurological control is lacking. If the neurological control is lacking, is this due to a motor stability programming issue (bad information coming from the body (poor proprioception, SIJ joint pain etc) or simply improperly learned behavior.<br />Good thought provoking article and I like the way you were able crowdsource your research (ie have me go look it up for you...haha).

I do not think any standards have been developed yet (assuming they exist). Here is a study I found investigating shoulder muscle latency. http://www.ncbi.nlm.nih.gov/pubmed/23137918<br />Since the hip and shoulder are similar, we may presume some of the characteristics will be similar.<br />There is this study which found no correlation between pain and non-pain patients. It did also demonstrate a latency with both groups in gmax firing relative to semimembranosous. http://www.ncbi.nlm.nih.gov/pubmed/20949236<br />I'll keep looking but it is interesting that there is not a lot of actual data immediately available to the US audience. <br />Let's ask Dr. Liebenson, surely he will point us in the right direction.<br />Anonymoushttps://www.blogger.com/profile/14808731734265200968noreply@blogger.com
