The effect of streching on delayed onset muscle soreness

Zapoznela mišična bolečina je pogosta posledica izvajanja telesne vadbe, ki je nismo vajeni, ali bolj intenzivne vadbe, zlasti ob ekscentrični aktivnosti mišic. Začutimo jo od 12 do 24 ur po telesni dejavnosti, njeni simptomi pa lahko variirajo od blage razdraženosti do hude bolečine s spremljajočo občutljivostjo, otekanjem in togostjo mišic. Za zmanjšanje simptomov zapoznele mišične bolečine se uporabljajo tudi tehnike raztezanja, s katerimi začasno ali trajno povečamo raztegljivost mehkih tkiv in tako dosežemo večjo prožnost in obseg gibljivosti. Namen pregleda je bil ugotoviti vpliv različnih tehnik raztezanja na zapoznelo mišično bolečino. Metode: Iskanje randomiziranih kontroliranih raziskav je potekalo v podatkovni zbirki PubMed. Rezultati: V pregled je bilo vključenih šest raziskav, v katerih so preučevali vpliv statičnega oziroma dinamičnega raztezanja na zapoznelo mišično bolečino, izzvano z vadbo. Izsledki treh raziskav so pokazali zmanjšanje zapoznele mišične bolečine, pri drugih treh raziskavah pa niso zaznali učinkov raztezanja na zapoznelo mišično bolečino, saj se je ta povečala. Zaključki: Izsledki raziskav so zelo heterogeni, zato jasnih in objektivnih zaključkov o učinkovitosti raztezanja ni mogoče podati. To nakazuje potrebo po dodatnih raziskavah o vplivu raztezanja na zapoznelo mišično bolečino.Delayed-onset muscle soreness is frequent after unaccustomed exercise or high-intensity exercise, particularly if it involves eccentric muscle contractions. Delayed-onset muscle soreness develops approximately 12 to 24 hours after physical activity, causing symptoms that can range from mild irritation to severe pain, and can be accompanied by tenderness, swelling, and muscle stiffness. Stretching is often used to reduce the symptoms and refers to any therapeutic manoeuvre that temporarily or permanently increases the extensibility of soft tissue structures and thus achieves greater flexibility and range of motion. The purpose of this review was to determine the effect of different stretching techniques on delayed-onset muscle soreness. Methods: The literature was searched in the PubMed database. Results: Six studies investigating the effect of static or dynamic stretching on exercise induced delayed muscle soreness were included in the literature review. Three studies reported a decrease in delayed-onset muscle soreness, whereas other three studies did not report the effect on delayed-onset muscle soreness, since the pain increased. Conclusions: Clear and objective conclusions about the methods\u27 effectiveness cannot be given due to very heterogeneous results from the reviewed studies. Further research is needed to determine the effect of stretching on delayed-onset muscle soreness
