Context:Recent studies have shown that the static stretch (SS) may adversely affect leg-muscle performance.Objectives:The authors examined the short-term effects of 2 stretching exercises on hamstrings muscle before and after exercise.Design:Crossover.Setting:Laboratory.Participants:9 healthy, physically active men.Interventions:There were 3 protocols in a randomized order with a 7-d interval: nonstretching (CON protocol), hamstrings static stretching (SS) with proprioceptive neuromuscular facilitation (PNF), and SS with kinesio-taping application on the hamstrings.Main Outcome Measures:Outcome measures included first-felt and maximum tolerant-felt range of motion (FROM and TROM), maximal knee-flexion peak torque (PT) at 180°/s, and hamstrings muscle stiffness.Results:Groups were not different at prestretching in terms of hamstrings flexibility, PT, and muscle stiffness. At poststretching, both stretching protocols showed significant increases in FROM and TROM (P < .05). Stiffer hamstrings muscle and decreased PT were found in both SS+PNF and CON protocols (P < .05). However, there was no significant difference in the SS+Taping protocol (P > .05).Conclusion:The stretching protocols improve hamstrings flexibility immediately, but after exercise hamstrings peak torque is diminished in the SS+PNF but not in the SS+Taping group. This means that SS+Taping can prevent negative results from exercise, which may prevent muscle injury.

Context:Proprioceptive neuromuscular facilitation (PNF) is commonly used before competition to increase range of motion. It is not known how it changes muscle response to rapid length changes.Objective:To determine whether PNF alters hamstring muscle activity during response to rapid elongation.Design:2 X 2 factorial.Setting:Laboratory.Participants:Twenty-four women; means: 167.27 cm, 58.92 kg, 21.42 y, 18.41% body fat, 21.06 kg/m2BMI.intervention:Measurements before and after either rest or PNF were compared.Main Outcome Measures:Average muscle activity immediately after a rapid and unexpected stretch, 3 times pretreatment and posttreatment, averaged into 2 pre-and post- measures.Results:PNF caused decreased activity in the biceps femoris during response to a sudden stretch (P= .04). No differences were found in semitendinosus activity (P= .35).Conclusions:Decreased muscle activity likely results from acute desensitization of the muscle spindle, which might increase risk of muscle and tendon injury.

BACKGROUND: The use of physical modalities in treatment of Chronic Low Back Pain (CLBP) is potentially beneficial, but the general evidence still leaves questions about its security application. OBJECTIVE: This study sought to investigate and compare the relative efficacy of Vertical Oscillatory Pressure (VOP) and Transverse Oscillatory Pressure (TOP) in the management chronic low back pain (CLBP) of mechanical origin. METHODS: A two-group, quasi-experimental design was utilized, involving a total of forty-two participants purposively recruited with due consideration of the specific inclusion and exclusion criteria. Five research questions were raised with corresponding hypotheses formulated for them, which were tested at 0.05 level of significance. The participants were randomly assigned to the VOP and TOP groups, and were subsequently managed thrice weekly for a duration of six weeks. The pain intensity rating, straight leg raising, and spinal range of motion were the outcome measures selected, which were assessed before and after treatment. Data were collected, organized, and analyzed using descriptive and T-Student test analytical statistics. RESULTS: The results of the study showed a significant difference in each of the outcome measures for both groups (p<0,05). CONCLUSION: This suggested that both VOP and VOP were relatively effective in managing CLBP.

Hamstring Flexibility

Background: flexibility that is one of basic aspects of any sport program , can be developed and acquired through various stretching exercises. This study examined the effect of six-weeks of static stretching on hamstring flexibility in high school females. Methods: Thirty healthy high school females aged 15 to 17 years were randomly assigned to one of two groups. The training group underwent static stretch training of the hamstring with a six-weeks protocol training sessions were 3 days per week, including 4 30-seconds stretches per day for each of subjects. The other group acted as control group. Before and after six-weeks of stretching, flexibility of the hamstring muscles was determined by Sit & Reach Test. Results: A significant increase in flexibility of hamstring was found in training group (mean 31cm to 39/87cm), and no significant difference was revealed in hamstring flexibility after the six-weeks static stretching for the control group. Conclusion: This study indicated that the static stretching significantly increased the hamstring flexibility and suggests that subjects use static stretching for increasing their hamstring flexibility.DOI: http://dx.doi.org/10.3126/ijls.v8i5.10914

Abstract BackgroundStretching is an important part of post-ankle-sprain rehabilitation, as well as an effective exercise for improving general ankle-joint performance. But the combination of stretching alongside muscle stimulation has not yet been extensively studied. Therefore the purpose of the present research is to compare the baseline, post- and follow-up effects of the proprioceptive neuromuscular facilitation (PNF) stretching technique combined with transcutaneous electrical nerve stimulation (TENS), as compared against the effects of the PNF stretching technique alone.MethodsSixty subjects with lateral ankle sprains were selected and randomly allocated to three groups: Experimental Group One (EG 1), Experimental Group Two (EG 2), and the Control Group (CG). Subjects in EG 1 received the PNF stretching technique combined with TENS. Subjects in EG2 received the PNF stretching technique alone. Both experimental groups received these treatments for 4 weeks (4 days/week); follow-up assessments were administered in the third and fifth weeks. CG received no treatment; outcome measures alone were assessed. Outcome measures comprised pain, flexibility, proprioception, range of motion, muscle strength, physical activity, and balance. A mixed-model ANOVA was used to analyze the effects of time factors and groups on these outcome measures.ResultsThere was significant interaction (time and group), and the time effect for all the outcome measures (p < 0.05). Physical activity, dorsiflexion, and balance in the medial, lateral, anterolateral, and anteromedial directions did not show a significant difference between the groups. EG 1 showed significant improvement for all the outcome variables between pre- and post-treatment and follow-up when compared to the other groups.ConclusionsThe present study showed that a 12-session treatment program of 3 weeks’ duration that combines PNF stretching with low-frequency TENS for post-ankle sprain subjects, compared against PNF stretching alone, produced significant improvements in balance, proprioception, strength, and range of motion. The study also showed that the treatment effect was sustained even after treatment was ceased after the follow-up assessment in the fifth week.Trial Registration:Human Research Ethics Committee approval for the trial (approval no.: (ECM#2019-26)Clinical trial was also registered in the Clinical Trials Registry – ISRCTN 18013941

Objective:To investigate the effect of a 12-wk weighted-jump-rope training program on shoulder strength.Design:Pretest to posttest experimental design.Setting:University sports physiotherapy laboratory.Participants:24 healthy volleyball players age 13-16 y.Intervention:Group 1 took weighted-rope training (n = 9), group 2 took unweighted-rope training (n = 8), and group 3 did not train with any specific program (n = 7).Main Outcome Measures:Players’ strength determined with an isokinetic dynamometer (Isomed 2000) at 180 and 60°/s on external and internal rotators, supraspinatus peak torque, and total work of the dominant shoulder. Kruskal–Wallis and Mann–Whitney U tests were used to determine the difference among the groups.Results:At pretraining evaluation, there were no significant differences in the test scores of the isokinetic test of full can and empty can between the groups at 60 and 180°/s. There was no statistically significant difference for 60 and 180°/s between pretraining and posttraining assessment (P > .05) except that total eccentric work increased in groups 1 and 3 but decreased in group 2 at 180°/s during the full can (P < .05). There was no significant difference among the groups between the pretraining and posttraining testing at both 180 and 60°/s for the empty can (P > .05). Internal-rotation values at 60 and 180°/s decreased for both peak torque and total work for all groups. External-rotation peak torque and total work at 60°/s increased for group 1. External-rotation peak torque and total work at 180°/s increased for all groups.Conclusions:The results indicate that a jump-rope training program is a good conditioning method for overhead athletes because of its potential benefits to shoulder strength.

Hot Pack

Background/aims High-intensity static stretching is assumed to increase the range of motion and/or decrease muscle stiffness; however, the effects of high-intensity static stretching on the quadriceps muscle have been debated. Hot pack application before high-intensity static stretching was assumed to decrease stretching pain, which is the main problem in high-intensity static stretching, and decrease quadriceps muscle stiffness. This study aimed to examine hot pack application before high-intensity static stretching on stretching pain, knee flexion range of motion, and quadriceps muscle stiffness. Methods In total, 21 healthy sedentary male participants randomly performed two interventions: high-intensity static stretching and hot pack application before stretching. Static stretching was performed at three 60-second stretching interventions with a 30-second interval. Then, a 20-minute hot pack was applied before high-intensity static stretching. The knee flexion range of motion and shear elastic modulus of the quadriceps muscle were measured by ultrasonic shear-wave elastography before and after the static stretching intervention. Results Stretching pain after hot pack application before stretching was lower than high-intensity static stretching alone. Significant increases were also found in knee flexion range of motion after both stretching interventions, but no significant difference was noted in the increase in the knee flexion range of motion with or without hot pack application. No significant change was found in quadriceps muscle stiffness in either intervention. Conclusions The results suggest that hot pack application before high-intensity static stretching could decrease stretching pain, but no significant difference in knee flexion range of motion increase was found.

Hip Extension

The purposes of this study were to determine the relationship of isokinetic quadriceps and hip extensor peak torque to isokinetic leg press peak torque and to determine the influence of hip position (seated vs. supine) on leg press peak torque. Forty subjects (20 males and 20 females) were tested bilaterally on the isokinetic dynamometer. Subjects were tested during knee extension, hip extension, seated leg press, and supine leg press. Intraclass correlation coefficient and standard error of measurement values revealed acceptable reliability for all tests. An analysis of variance revealed significant dominant versus nondominant differences in all tests except hip extension. A repeated measures analysis of variance revealed no significant difference between seated and supine leg press peak torque. Finally, stepwise regression revealed a significant relationship between knee extension and leg press peak torques, with hip extension adding only minimally to the explained variance. These data suggest that knee extension and leg press peak torque assess similar muscle performance characteristics. Further research involving electromyographic analysis is recommended to determine the influence of other muscles on leg press force performance.

Context:There is limited information on the effects of throwing on shoulder proprioception and strength.Objective:Examine shoulder proprioception and strength following throwing.Design:2x3 mixed-subject design.Setting:Research laboratory and outdoor facility.Participants:23 male college students (age = 22 ± 2.9yr, ht = 178 ± 11.3cm, wt = 72 ± 7.7kg, 22 right-handed 1 left-handed).Intervention:Subjects were pretested for proprioception, measured by active reproduction of passive positioning (ARPP). Strength was quantified using 1RM and an average peak torque at 120º/sec for internal and external shoulder rotation. Following pretesting, subjects (excluding control) completed 75 throws at 75% maximum immediately followed by posttesting.Main Outcome Measures:Pre and post ARPP absolute error and strength changes.Results:Significant difference in the pre and posttest ARPP values for throwing groups but no difference for the control group. There was no significant difference from pre to post on the strength tests for any groups.Conclusion:Results indicate that repetitive throwing affects proprioception while not affecting strength.

ObjectivesTo understand the effect of attendance at departmental Christmas parties on cohesion and teamwork within the healthcare setting.Method (design/setting/participants/interventions/outcome measures)We used the ‘Team Development Measure’ questionnaire to assess team cohesiveness among healthcare professionals before and after departmental Christmas parties took place. A pooled mean score (PMS) of responses was used to compare between groups.ResultsThere were no significant differences in perceived measures of team cohesion when comparing responses before (PMSbefore=1.86±0.20) and after (PMSafter=1.91±0.22) the departmental Christmas party (p=0.37), nor was there a significant difference when comparing responses from attendees (PMSbefore=1.83±0.23, PMSafter=1.89±0.24, p=0.52) or non-attendees (PMSbefore=1.84±1.47, PMSafter=1.83±0.15, p=0.91). No difference was observed between professional groups (PMSdoctors=1.85±0.23, PMSnurses=1.95±0.18, p=0.064).ConclusionAttendance at departmental Christmas parties does not seem to result in improved team cohesion.
