Filter by:The invesitgators performed a randomized controlled trial on collegiate sprinters to explore the combined effect of the NHE and KT and randomly allocated the subjects into the experimental (NHE+KT) or control (NHE) group by an independent researcher using the sealed envelopes method. To calculate the sample size, a Cohen's d effect size of 0.4, an alpha level of 0.05, a test power of 0.95 were configured to G*Power software, at least 34 samples were computed. Considering the dropouts, 40 male collegiate sprinters were enrolled, explained the procedures of this study and voluntarily written informed consent. Inclusion criteria was that participants must be male, aged 18 years or older, training at the university level at least 4 times per week, with no history of lower limb injury within the last 6 months and no previous experience of the NHE or KT. Participants who had lower limb mobility limitation or injury especially HSI within 6 months and associated musculoskeletal, respiratory or cardiovascular diseases and was allergic to kinesio tape were excluded.
Ninety male subject will be divided into three group: a younger group (18-22y), an older group (30-40y) and a control group (18-40y). The study comprises 3 phases. PHASE 1: baseline strength and stiffness measurements of the hamstring muscles, PHASE 2: 12 week Nordic Hamstring strength training program (not for the control group) and PHASE 3: final strength and stiffness measurements. The aim of this study is twofold, namely to investigate (1) whether there is a difference in baseline stiffness of the hamstring muscle complex between different age categories and (2) the evolution of hamstring muscle stiffness during an eccentric strength training program within the different age groups. These two research questions could ultimately lead to a possible answer on the question if the higher probability of HSI (=hamstring strain injury) in the older age category with the lowest levels of eccentric hamstring strength could be due to an age-related difference in hamstring stiffness.
This project was a Randomized clinical trial conducted COMPARATIVE STUDY OF POST ISOMETRIC RELAXATION AND MULLIGAN BENT LEG RAISE ON HAMSTRING TIGHTNESS IN HIGH SCHOOL STUDENTS
The study aims to investigate acute effects of ballistic hamstring stretching, hamstring extender exercise, and kinesiotaping application on viscoelasticity of hamstrings and standing long jump performance on rowers.
This study aims to compare the effect of two hamstring strengthening programs on hamstring muscle strength in university students. 60 participants will be recruited for this study. They will be randomly assigned to one of two 6-week hamstring strengthening programs, namely the single leg bridge exercise and the Nordic hamstring exercise protocol, and one control group. Eccentric and isometric hamstring strength, gluteal strength and will sprint speed will be measured before and after the intervention.
The aim of this research is to compare the effects of dose response of Nordic hamstring exercise on muscle strength, agility and speed in athletes a randomized controlled trial done at JKD cricket academy and sports centre, Peshawar. The sample size was 34. The subjects were divided in two groups, 17 subjects in Group 1 which will do high volume Nordic hamstring exercise and 17 in Group 2 which will do low volume Nordic hamstring exercise. Study duration was of 6 months. Sampling technique applied was non probability purposive sampling technique. Only 18-30 years athletes with BMI between 18.5-24.5 kg/m2 were included. Tools used in the study are Single leg hamstring bridge (SLHB), Agility t-test, 30-m speed test and muscles size .Data will be analyzed through SPSS 21.
Introduction: the hamstring muscles has a great tendency to decrease its extensibility, originating a pathology with a own clinical entity, the Short Hamstring Syndrome (SHS), in addition to other problems on adjacent structures. All this present a great socioeconomic impact in the investigator's society. Various techniques have been demostrated to prduce an increase in flexibility, among which are the fascial techniques. Objective: to evaluate the immediate efficacy of the treatment of the lumbar fascia in the flexibility of the hamstring musculature. Methods: 41 women between 18 and 39 years old, in two groups. The experimental group received a technique of fascial stretching in the lumbar area while the control group participated in an off magnetotherapy machine. The hamstring flexibility in both lower limbs was measured by the Straight Leg Raising Test (SLR) and the Passive Popliteal Angle Test (PKE).
Athelts that meet the inclusion criteria will be randomized into two groups. The experimental group will receive an 8-week (3 days per week) specificl protocol based on hamstring strengthening (isometric, concentric and excentric exercises), and the control group will not receive any additional exercise. The aim of the study is to investigate the changes in hip and knee muscle strength, in the extensibility of cuadriceps, hamstrings and hip abductors, in the physical functions and in the final marks.
Investigate the efficacy of the inercial Flywheel training protocol in modifying the architecture and function of the hamstrings in patients with a history of structural muscle injury vs conventional training. The researchers hypothesize that inercial Flywheel training protocol will be a useful strategy in the modification of the architecture and function of the hamstring in patients with a history of indirect structural muscle injury and decrease the recurrence.
The aim of this study is to build on previous published work, which has indicated lumbar mobilisations have the ability to increase hamstring extensibility and decrease muscle activity. The primary aim of this project is investigate if lumbar mobilisations have an affect on the Nordic Hamstring exercise. Aim: To investigate the short-term effects L4 and L5 Unilateral Posterior Anterior (UPA) Mobilisations on the lumbar spine on the Nordic Hamstring Exercise. Measures will include hamstring peak torque, sEMG activity and knee angle at first rapid change in angular acceleration.
