“…In studies that showed muscular performance decreased after static stretching (4,7,8,9,10,17,23,25), a single muscle group was statically stretched for 100 seconds to 30 minutes. However, in warm-up, the muscle groups that are used in actual activity need to be stretched in a limited time (1).…”

“…7 However, stretching has been shown to acutely decrease explosive muscle performance, 8,9 and in addition, acutely decrease gastrocnemius tendon stiffness in males, 10 thus increasing tendon mechanical strain for any given load. Stretching or tensile loading protocols are also used in the preconditioning of tendon grafts for ACL reconstructions.…”

Stretching is commonly used prior to exercise, as it is thought to reduce the risk of injury, and it is also used in the preconditioning of tendon grafts. As tendon properties have been shown to be different between genders, it is proposed that stretching will differentially affect the structure. Here we examine the effect of acute stretch on the mechanical properties of both male and female medial gastrocnemius tendon. Female [20 years AE 1 (SEM), n ¼ 17] and male (22 years AE 1, n ¼ 18) subjects underwent a 5-min passive dorsiflexion stretch. Prior to and post stretch medial gastrocnemius tendon stiffness (K), length (l) and cross-sectional area (csa) were measured using ultrasonography and dynamometry. Stiffness and Young's modulus (e) were significantly reduced with stretch for both genders (p < 0.05). Females showed significantly (p < 0.05) greater pre-to poststretch decreases in K (22.4 vs. 8.8%) and e (20.5 vs. 8.4%) in comparison to males. The present results show that stretching acutely reduces stiffness of the medial gastrocnemius tendon in females and males, with females showing significantly greater change. The observed disparity between genders may be due in part to variations in tendon moment arm and intrinsic differences in tendon composition. These differential changes in tendon mechanical properties have functional, motor control, and injury risk implications, as well as possible implications for preconditioning of tendon grafts. ß

“…Therefore, the effect of static stretching on muscular performance with DCER muscle action should be clarified in order to determine whether the use of static stretching is inappropriate as a part of a warm-up. The effect of static stretching on muscular performance with concentric DCER muscle action was investigated in a few studies (14,21), but only the effect on relatively heavy loaded performance was examined. Thus, the effect of static stretching on muscular performance with concentric DCER muscle actions under relatively light or moderate loads was not clarified.…”

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 twelve healthy male subjects after two types of pre-treatment. The pre-treatments included 1) static stretching treatment performing six types of static stretching on leg extensors (4 sets of 30-sec each with 20-sec rest periods; total duration: 20-min) and 2) non-stretching treatment by resting for 20 minutes in a sitting position.Loads during assessment of the power output were set to 5%, 30% and 60% of the maximum voluntary contractile (MVC) torque with isometric leg extension in each subject. 478.6 ± 77.5 W vs. 523.8 ± 97.8 W). The present study demonstrated that relatively extensive static stretching significantly reduces power output with concentric DCER muscle actions under various loads. Common power activities are carried out by DCER muscle actions under various loads. Therefore, the result of the present study suggests that relatively extensive static stretching decreases power performance.
