Duration Dependent Effect of Static Stretching on Quadriceps and Hamstring Muscle Force

Sports, 2018
The aim of this study was to determine the acute effect of static stretching on hamstring and quadriceps muscles’ isokinetic strength when applied for various durations to elite athletes, to investigate the effect of different static stretching durations

Hamstring Muscles: Architecture and Innervation [PDF]

Cells Tissues Organs, 2005
Knowledge of the anatomical organization of the hamstring muscles is necessary to understand their functions, and to assist in the development of accurate clinical and biomechanical models. The hamstring muscles were examined by dissection in six embalmed human lower limbs with the purpose of clarifying their gross morphology.

No difference in osteoarthritis, but less graft failures after 5 years, comparing anatomic double‐bundle to anatomic single‐bundle ACL reconstruction

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose The purpose of this study was to compare the incidence of knee osteoarthritis (OA) between the anatomic single‐bundle (SB) and anatomic double‐bundle (DB) anterior cruciate ligament (ACL) reconstruction technique after 5‐year follow‐up (FU).

Sonographic landmarks in hamstring muscles [PDF]

Skeletal Radiology, 2019
The ultrasound examination of hamstrings inspires respect due to the connective complexity of their structures, particularly for sonographers who are not used to this kind of study. Therefore, it is important to know the specific ultrasound reference points that facilitate the location of the hamstring structures, dividing them into four areas of ...

How statistically fragile are randomized controlled trials comparing quadriceps tendon autografts with hamstring or bone‐patellar tendon‐bone autografts in anterior cruciate ligament reconstruction?

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose To determine the statistical fragility of randomized controlled trials (RCTs) which compare the use of quadriceps tendon (QT) autografts to either hamstring tendon (HT) or bone‐patellar tendon‐bone (BPTB) autografts in anterior cruciate ligament reconstruction (ACLR).

Higher isokinetic quadriceps peak force is associated with a patient‐acceptable symptom‐state 1 and 3 years after ACL reconstruction

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose The main purpose was to determine cut‐off values for absolute (QNm/kg) and relative (QLSI) isokinetic knee extensor (KE) strength for achieving a patient‐acceptable symptom state (PASS) in the Knee injury and Osteoarthritis Outcome Score (KOOS) subscales and for different age groups to determine the association between QNm/kg and QLSI ...

Age and Sex Differences in Physical Performance Among Adolescent Team Sport Athletes. [PDF]

Eur J Sport Sci
ABSTRACT The study aimed to explore the differences in physical performance characteristics across various age groups (U14, U16, and U18) and sexes in adolescent team sport athletes. 473 adolescent Norwegian football and handball players were recruited for anthropometrical and physical performance testing. Performance improved with age in both boys and

Couple Control Model Implementation on Antagonistic Mono- and Bi-Articular Actuators [PDF]

arXiv, 2014
Recently, robot assisted therapy devices are increasingly used for spinal cord injury (SCI) rehabilitation in assisting handicapped patients to regain their impaired movements. Assistive robotic systems may not be able to cure or fully compensate impairments, but it should be able to assist certain impaired functions and ease movements.

Anterior cruciate ligament reconstruction with six and eight‐strand hamstring tendon autografts produces adequate graft dimensions and functional outcomes: A systematic review

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose This study aims to summarize the graft dimensions, failure rates, return‐to‐sport rates and patient‐reported outcome measures (PROMs) following anterior cruciate ligament reconstruction (ACLR) with six or eight‐strand hamstring tendon autografts (6SHG or 8SHG).

Static stretching duration needed to decrease passive stiffness of hamstring muscle-tendon unit

Journal of Physical Fitness and Sports Medicine, 2019
Static stretching (SS) is widely used to decrease and retain the passive stiffness of the muscle-tendon unit in clinical and athletic settings. It is important to consider the minimum SS duration required to decrease the passive stiffness of the ...
