Pain severity is associated with muscle strength and peak oxygen uptake in adults with fibromyalgia – free full-text PMC4014369/ – 2014 May
I find this relationship of muscular weakness with pain in my own bouts of cycling: the more pain I have, the less I’m able to push the pedals. My pain seems to depress many aspects of my physical functioning, so this study only reinforces what I suspect many of us have experienced.
The associations between pain, lower extremity strength, and aerobic conditioning have not been widely investigated in adults with fibromyalgia (FM).
The principle objective of this study was to investigate the relationship between pain severity and knee strength in patients seeking treatment for FM.
A secondary objective was to investigate the relationship between pain scores and aerobic conditioning.
Fibromyalgia (FM) is characterized by the presence of diffuse widespread pain.
Previous studies suggest FM is also associated with reduced knee strength and decreased levels of aerobic conditioning.
Knee strength has been preferentially used because of its critical role in performing routine functional tasks, and easy accessibility of the lower extremity for strength testing.
Three measures of knee strength (isokinetic extensor, isokinetic flexor, isometric extensor) were quantified in the dominant leg of 69 adults with FM using a dynamometer at speeds of 60 degrees per second (60°/s) and 180°/s.
Peak oxygen uptake (VO2) was assessed using a cycle ergometer, and pain was assessed using the pain severity subscale of the Multidimensional Pain Inventory.
In univariable linear regression analyses using pain severity as the dependent variable,
lesser values of
- isokinetid knee extensor strength at 60°/s (P=0.041) and 180°/s (P=0.010),
- isokinetic knee flexor strength at 60°/s (P=0.028) and 180°/s (P=0.003), and
- peak VO2 uptake (P=0.031)
were predictive of greater pain severity scores.
In multiple variable linear regression models adjusted for age, sex, body mass index, and opioid use, the following associations retained statistical significance;
- isokinetic knee extensor strength at 60°/s (P=0.020) and 180°/s (P=0.003),
- isokinetic knee flexor strength at 60°/s (P=0.015) and 180°/s (P=0.001), and
- peak VO2 uptake (P=0.014).
The main findings from this study were that lesser values of isokinetic knee strength and peak VO2 uptake were predictive of greater pain severity scores.
These results build on the findings of previous investigations, but ongoing research is needed to further characterize the effects of strength and peak VO2 uptake on the pathophysiology of FM.

Another BIG Duh study!
Who Aerv these peeps?
No study needed, Just ASK!
idiOts we deal with, sheeesh.
Still hassle getting here.; Click link email.; Get bad gateway page.; Hit bookmark main page.; Next hope on 1st page.; Click.; Or next page.; Click.
What gives w/Some of my writing, Tight Code.; Miss it.
Might be easier on FB, eh?
If “I” had Screamed bloody Murder, after being invaded by an NSA contractor practicing on ME, in Canada, evidently a Free Fire Zone, likely still, shhhhhhh!
In 2010, after Moi gotz PiSSED a’Bout, d’Gulf, Cradle of Life, one of mebbe 5 on this spinning ball of… a LOTTA WATER!!! We LiVE, courtesy of it.
Most, BenDer/DunDat! is a Sterile Desert, Ask Me, aGain.. dun it, Just unkorked, & Wrote it Down finally… On FB!
Whom Would NOT be where they are today, because… IPO then.
Damned Good Thing that “I”, Loved Groups, Saw What they DiD, for “My’ Peeps, stuffed the invaded Drive, backed up several locations, stuffed into Safety Deposit yet unopened, Costing Moi $$$.99
F*ck it, I Own it.
Hopefully Last Time I’ll ever toot That horn Hard, but…
Damn them, for Not Listening.
Bite Moi FB, DARE Yah.

Write up on it two years back, finally making it out of their Toolkit.
But pipelines in & out are WiDE Open, to snoopeds, Ad Men, And Services, where “I” tripped the wires, the Guys running CaPTcha for them, then…. Moi got talking2them, through the CaPTchas, not. chitting. Here.
Doable, though the use of Caps, R’not, to communicate w/them.
Worked/Studied Language Physio Pathology, an offshoot of working w/TBi folk, Head Injured, needing Badly other ways to comm, BiG interest of mine, Learn what Scares Moi in & out, also what interests.
Rodrigiuz/Gonzales got in the Convo, Life got Weird, stressed my Wifely, to rushing out of house to Do something, rattleded, rolled over BiLL-e, Cuttest Kitten Evah, w/a Future!
Spent afternoon at Vets incompetant.; Hard Way Out4Bill-e.
Ripped.; Never Forgiven what CAUSED That!

Tour inside the gears, thank Yew!
tick tick tick… BenDer/DunDat too.

Under OutRageous ProVOCations, in Lif, never finished till it’s oVah.
How That Jukeboz, wuz built, on FB LiVin!
Try to keep peeps Alive, Never HURT Intentional another Human in Life, cept for One Exception, that, as Usual, Cheated moi of his Revenge, Dying on Moi 12 hour too Early, Looooong story, hurtfull to tell, but still, bouncing in there.
If on FB, Visit Photos, take a trip w/me in ***Travels***
Beware the sting in the tail.
Might even LOOK@Piece of work again, have an Immaculate Rant Born on The Pharma Trumpies blog, bout that.
Writing just breathes out, when in the thought stream swimming along, triggered, Out it Pops, Just RiDE the P*ss out of it, at heart/profession, jus another Equipment Operating Engineer, jus did that My way2.
We try2 have fun ‘n Lif, racing towards Finishing it, Righteous/Bodaciously, to borrow an Old USCG bud’z term. We Like Words, Roll in them, & Play, thoughtfully, hopefully.
Might still be here in cache, quote, Main One I live by.
Oooops! WALLOWTEXT BRB… Hatev that, too much scolling/No direct link, will pull from origin.
