“…During MVC, one end of the sling wire was connected to the ankle strap, and the other end was connected to the sling system (Marpe Inc., Jeonju, South Korea) fixed on the ceiling to help with the isometric contraction of the lower extremity (Figure 1B) (23). Verbal encouragement was provided to the subjects during MVC.…”

Purpose: Previous studies that examined pain after submaximal isometric contractions at different intensities are limited in that they used different intensities randomly. The present study aimed to examine the change in pain depending on the order of submaximal isometric contractions performed at two different intensities and inter-and intra-individual differences in pain responses.Methods: Twenty-nine volunteers participated (mean age=22.10±1.60 years) to the study. Hamstring flexibility was measured in the supine position. Maximal voluntary contraction (MVC) was measured during hip extension. Submaximal contractions were performed at two different target intensities: 25% and 75% of MVC. Visual Analogue Scale (VAS) was used to measure the pain after submaximal contractions. Group A (n=15) performed submaximal contraction in 25% to 75% of MVC in the 1st period and 75% to 25% of MVC in the 2nd period. In Group B (n=14), the submaximal contraction was performed in each period in the opposite order of Group A.Results: There was a significant decrease in pain in Group B during the 2nd period (p<0.05). The VAS at 75% of the MVC showed a significant decrease at 25% of the MVC (p=0.011). Correlations were observed between flexibility and 1st-period VAS score (p=0.048) and 2nd-period VAS score (p=0.036) and between the VAS scores in the 1st and 2nd periods (p<0.001). Conclusion:Pain intensity could be perceived differently depending on the order of sequential application, even when the intensities are identical, and might be more clinically useful in the analysis of intra-individual comparisons.

“…Terkait dengan cara meningkatkan kelentukan. Terdapat penelitian terdahulu yang menunjukkan bahwa peregangan yang dilakukan secara berulang pada setiap kali latihan dengan intensitas tinggi dan intensitas sedang mampu meningkatkan kelentukan dibandingkan dengan peregangan intensitas rendah (Lim, 2018). Selain itu, hasil penelitian lain yang menunjukkan bahwa latihan peregangan statis lebih efektif terhadap peningkatan kelentukan togok dibandingakan dengan latihan peregangan dinamis.…”

Abstract: The results of preliminary observations of the basketball zigzag dribble test, as many as 60% of participants could not do it correctly and accurately. The purpose of this study was to examine the effect of basketball dribble zigzag training using poles and cardboard on improving basketball dribble skills in basketball extracurricular activities at SMA Nasional Malang. The experimental research design, a sample of 40 participants was taken using a purposive proportional systematic random sampling technique from a total of 40 male participants. Fcount 76.22 is more than Ftable α equal to 0.05 4.17. While the results of the advanced test of the LSD technique of dribbling zigzag basketball practice using T count -6.283 and T table 1.685, the results of the advanced test of the LSD technique of dribble zigzag basketball training using cardboard T count 11.364 and T table 1.685, there is an effect of dribble training. zigzag basketball using poles and cardboard to improve basketball dribble skills. A basketball zigzag dribble using a pole is better than a basketball zigzag dribble exercise using cardboard.

“…During stretching, numerous factors may influence the quantitative increase in flexibility; among them, the intensity, in particular, is considered a key factor [2]. Previous studies examining the effects of the different intensities of stretching on flexibility confirmed that moderate-intensity or above stretching leads to a significant increase in flexibility; moreover, low-intensity stretching also sometimes leads to an increase in flexibility [3][4][5]. Nevertheless, previous studies conducted in laboratory conditions have several limitations when it comes to the clinical application of their findings.…”

“…First, the order of different intensities poses a limitation. In previous studies where more than two different intensities were used, the method of applying the intensity could be categorized into two types: the stretching may be performed in a randomized order for all intensities within a defined subject [4,[6][7][8] or with only one intensity randomly assigned to each subject [3,5,9]. The former method applies randomized order such that the order of different intensities on flexibility cannot be analyzed.…”

“…Second, visual feedback is different in clinical settings. In most previous studies, the contraction force being measured in the experiment was provided to the subjects in real time to aid them in self-regulation of the muscle contraction according to the target intensity [3,5,9,12]. The subjects in such cases were able to monitor the contraction force as a numerical value so that it is possible to perform a muscle contraction of the desired level based on a clear differentiation between two or more intensities assigned for the experiment.…”

In most previous studies of PNF stretching performed at different intensities, the subjects were provided with the intensities in a randomized order. In addition, subjects were aided in maintaining a steady level of contraction force using a dynamometer as visual feedback. However, such a procedure differs from the procedure used in actual clinical settings. This study aimed to examine the effect of the applied order of three different intensities of PNF stretching on the ability to regulate the contraction force and increase muscle flexibility. During the 1 st period, three different stretching intensities were applied in the order of 25%, 50%, and 75% of MVC in the group A and in the order of 75%, 50%, and 25% of MVC in the group B. This order was reversed during the 2 nd period. The contraction force was measured using the strain gauge and hamstring flexibility was measured using active knee extension. There was no significant difference between target and contraction intensity at three target intensities in both groups. Additionally, contraction forces between different intensities clearly were distinguished by subjects in both groups. In Group A, increase in flexibility was significantly higher in the 1 st period than in the 2 nd period. Healthy adults could clearly differentiate and regulate contraction intensity when the intensities were differentially applied at 25% intervals. The higher target intensity compliance and increase in flexibility may be anticipated when progressively increase intensity was applied, compared to the same factors in reverse order.
