Misc Studies related to DOMS

Neutralization of muscle tumour necrosis factor alpha does not attenuate exercise-induced muscle pain but does improve muscle strength in healthy male volunteers

Authors: Rice,T.L.; Chantler,I.; Loram,L.C.
Source: Br.J.Sports Med.,

Conclusion: "TNF-alpha (Tumour Necrosis Factor) does not affect muscle soreness associated with unaccustomed exercise, but may improve the recovery of muscle function."

Muscle pain prophylaxis

Authors: Dudley,G.A.
Source: Inflammopharmacology, 1999, 7, 3, 249-253

Conclusion: "The Future studies need to assess the effect of novel physical activity upon functional capacity as influenced by NSAIDs (non-steroidal AIDs ) in older and/or inactive individuals who seem especially vulnerable to contraction induced muscle fiber injury."

Methods to quantify intermittent exercises

Authors: Desgorces,F.D.; Senegas,X.; Garcia,J.; Decker,L.; Noirez,P.
Source: Appl.Physiol.Nutr.Metab., 2007, 32, 4, 762-769

Conclusion: "So WER (work endurance recovery) can quantify varied intermittent exercises and makes it possible to compare the athletes' TL (Training load). Furthermore, WER (work endurance recovery) can also assist in comparing athlete responses to training programs."

Fear of pain influences outcomes after exercise-induced delayed onset muscle soreness at the shoulder

Authors: George,S.Z.; Dover,G.C.; Fillingim,R.B.
Source: Clin.J.Pain, 2007, 23, 1, 76-84

Conclusion: "With the exception of muscle force production, fear of pain had a consistent influence on shoulder DOMS (Delayed Onset Muscle Soreness) outcomes, even after controlling for pain intensity. This study suggests fear of pain may be a relevant psychologic factor to consider in clinical studies investigating the development and treatment of chronic shoulder pain."

The effect of eccentric exercise on position sense and joint reaction angle of the lower limbs

Authors: Paschalis,V.; Nikolaidis,M.G.; Giakas,G.; Jamurtas,A.Z.; Pappas,A.; Koutedakis,Y.
Source: Muscle Nerve, 2007, 35, 4, 496-503

Conclusion: "The Position sense was impaired only immediately post-exercise (probably due to muscle fatigue), whereas impairment of the reaction angle to release persisted up to 3 days post-exercise (probably due to muscle damage). Attenuation of position sense and joint reaction angle of the lower limbs after damaging activities is a serious functional limitation that may lead to an increase risk of injury, particularly in older populations."
