Aim: It is well documented that static stretching acutely increases range of motion (ROM) in a dose-dependent manner. However, most previous studies have utilized intermittent stretching protocols, and it is not known if intermittent and continuous stretches elicit different changes in joint ROM and, in particular, in flexibility-trained subjects. The aim of this study was to examine changes in hip joint ROM after an intermittent or a continuous static stretching protocol of equal total duration. Material & Method: Twenty-seven female subjects (age, 19.9 ± 3.0 years; height, 167.3 ± 6.1 cm; body mass, 58.2 ± 5.2 kg), 14 artistic and rhythmic gymnasts, and 13 recreationally active participants performed 3 min of intermittent (6 × 30 s with 30 s rest) or continuous stretching (3 min) of the hamstring muscles, with an intensity of 8–9 on a 10-point visual analogue scale. Hip joint ROM was measured for both legs after warm-up and immediately after stretching. The same individuals performed both conditions with alternate legs in a randomized, counterbalanced order. Data were analysed using mixed-model three-way ANOVA. Results: In the untrained participants, only intermittent stretching increased ROM by 13% (from 91.0 ± 7.2° to 102.4 ± 14.5°, p = 0.001), while continuous stretching did not affect ROM (from 92.4 ± 6.9° to 93.1 ± 9.2°, p = 0.99). In the trained participants, both stretching types equally increased ROM by ~6% (continuous, 140.9 ± 20.4° to 148.6 ± 18.8°, p = 0.047; intermittent, 141.8 ± 20.3° to 150.0 ± 18.8°, p = 0.029). Conclusions: The different effect of intermittent vs. continuous stretching on hip ROM between trained and untrained subjects suggests that stretching mode is an important variable when examining the acute effects of static stretching on ROM enhancement.

Flexibility is an important component in Karate. Stretching is one way to improve the Range of Motion (ROM). Stretching static is one type of stretching that can be used. Long static stretching with low intensity is the safest form of stretching and gives significant results. The purpose of this study to determine: 1) Effect of active static stretching against on Hip joint ROM on female Karate athletes of UMS. 2) The effect of passive static stretching on hip joint ROM on female Karate athletes of UMS. 3) To know the effect of active and passive static stretching effect on Hip ROM on female Karate athletes of UMS. The research used Quasi Experimental Research method. Sample of research are 10 female karate athletes of UMS. It has 2 free variables and 1 dependent variable. Data is numeric and analyzed with SPSS 20.0. The result of research are: 1) T test result show sig 0.000<0,05, hence show significant influence. 2). sig 0.000<0.05, then show a meaningful influence. 3) visible sig 0.024, so it can be concluded there is a significant effect difference between active and passive static stretching against ROM on  female karate athletes of  UMS. From the results of this study can be concluded, 1) there is a significant effect between the giving of active static stretching to increase ROM of hip joint. 2) there was a significant effect between giving static passive stretching to increasing ROM of hip joint. 3) there is a difference significant effect between active and passive static stretching against increasing  ROM on hip joint.

Biomechanical Comparison

Background The incidence of shoulder and elbow injuries in adolescent baseball players is rapidly increasing. One leading theory about this increase is that breaking pitches (such as the curveball) place increased moments on the dominant arm and thereby increase the risk of injury. Hypothesis There is no difference in the moments at the shoulder and elbow between fastball and curveball pitches in adolescent baseball pitchers. Study Design Controlled laboratory study. Methods Thirty-three adolescent baseball pitchers with a minimum of 2 years of pitching experience underwent 3-dimensional motion analysis using reflective markers aligned to bony landmarks. After a warm-up, pitchers threw either a fastball or curveball, randomly assigned, from a portable pitching mound until 3 appropriate trials were collected for each pitch technique. Kinematic and kinetic data for the upper extremities, lower extremities, thorax, and pelvis were collected and computed for both pitch types. Statistical analysis included both the paired sample t test and mixed model regression. Results There were lower moments on the shoulder and elbow when throwing a curveball versus when throwing a fastball. As expected, speed for the 2 pitches differed: fastball, 65.8 ± 4.8 mph; and curveball, 57.7 ± 6.2 mph (P <. 001). Maximal glenohumeral internal rotation moment for the fastball was significantly higher than for the curveball (59.8 ± 16.5 N·m vs 53.9 ± 15.5 N·m; P <. 0001). Similarly, the maximum varus elbow moment for the fastball was significantly higher than for the curveball (59.6 ± 16.3 N·m vs 54.1 ± 16.1 N·m; P <. 001). The wrist flexor moment was greater in the fastball, 8.3 ± 3.6 N·m, than in the curveball, 7.8 ± 3.6 N·m (P <. 001), but the wrist ulnar moment was greater in the curveball, 4.9 ± 2.0 N·m, than in the fastball, 3.2 ± 1.5 N·m (P <. 001). Relatively minor motion differences were noted at the shoulder and elbow throughout the pitching motion, while significant differences were seen in forearm and wrist motion. The forearm remained more supinated at each point in the pitching cycle for the curveball but had less overall range of motion (62° ± 20°) than with the fastball (69° ± 17°) (P <. 001), and the difference in the forearm pronation and supination moment between the pitches was not significant (P =. 104 for pronation and P =. 447 for supination). The wrist remained in greater extension during the fastball from foot contact through ball release but did not have significantly different total sagittal range of motion (53° ± 11°) when compared with the curveball (54° ± 15°) (P =. 91). Conclusion In general, the moments on the shoulder and elbow were less when throwing a curveball than when throwing a fastball. In each comparison, the fastball demonstrated higher moments for each individual pitcher for both joints. Clinical Relevance The findings based on the kinematic and kinetic data in this study suggest that the rising incidence of shoulder and elbow injuries in pitchers may not be caused by the curveball mechanics. Further evaluation of adolescent and adult baseball pitchers is warranted to help determine and subsequently reduce the risk of injury.

Stretching Exercises

Although warm-up and stretching exercises are routinely performed by gymnasts, it is suggested that stretching immediately prior to an activity might affect negatively the athletic performance. The focus of this investigation was on the acute effect of a protocol, including warm-up and static and dynamic stretching exercises, on speed during vaulting in gymnastics. Eleven boys were asked to perform three different protocols consisting of warm-up, warm-up and static stretching and warm-up and dynamic stretching, on three nonconsecutive days. Each protocol was followed by a “handspring” vault. One-way analysis of variance for repeated-measures showed a significant difference in gymnasts’ speed, following the different protocols. Tukey’s post hoc analysis revealed that gymnasts mean speed during the run of vault was significantly decreased after the application of the static stretching protocol. The findings of the present study indicate the inhibitory role of an acute static stretching in running speed in young gymnasts.
