Introduction: Traditionally, static passive stretching has been used by coaches and athletes as a warm-up technique in an attempt to promote better performances. However, the results of recent research have shown that passive muscle stretching can diminish the peak force output of subsequent maximal concentric contractions of the quadriceps. Aside from clinicians’ benefits, athletes competing i...

The purpose of the present study was to clarify the effect of static stretching on muscular performance during concentric isotonic (dynamic constant external resistance [DCER]) muscle actions under various loads. Concentric DCER leg extension power outputs were assessed in 12 healthy male subjects after 2 types of pretreatment. The pretreatments included (a) static stretching treatment performi...

This study aimed to compare the effect of different static stretching durations followed by dynamic stretching on repeated sprint ability (RSA) and change of direction (COD). Twenty-five participants performed the RSA and COD tests in a randomized order. After a 5 min aerobic warm up, participants performed one of the three static stretching protocols of 30 s, 60 s or 90 s total duration (3 str...

Introduction: Delayed onset muscle soreness is known, muscle pain, soreness and discomfort feeling approximately 24-48 hours after exercise. The increased serum biochemical enzymes after acute exercise or unaccustomed training were reported in some studies. The main purpose of this study was to search the effect of warm-up before eccentric contractions on DOMS, biochemical enzymes changes and N...

Res. 19(1):27–32. 2005.—This study compares the effects of 3 common stretching techniques on the length of the hamstring muscle group during a 4-week training program. Subjects were 19 young adults betw...

Background: For decades, static stretching has been the standard benchmark for training programs, because it has been shown to increase flexibility compared with other methods of stretching. Objective: The current study investigated and compared the effects of active dynamic stretching and passive static stretching on hamstring tightness. Me...

the purpose of the present study was to investigate whether duration of static stretching could affect the maximal voluntary contraction (mvc) and flexibility of hamstring muscles. 10 male physical education students randomly performed three warm-up protocols on different days. the protocols included: a) five minutes of treadmill run and 45 seconds (3×15 seconds) of static stretching of hamstri...

methods in this study, 16 skilled female gymnasts (mean age of 9.62 ± 1.45 years) were randomly categorized to two general warm-up with no stretching (ns, n=8) and general warm-up plus static stretching (ss, n=8) groups. the warm-up protocol included a 10-minute jogging, and the static stretch (ss) protocol included stretching programs on the different parts of body during four weeks, three tim...
