NCT07274566
This study aims to examine the effects of an eight-week Exer-Genie®-assisted speed and agility-balance-coordination (ABC drill) training program on sprint performance, hamstring muscle strength, and vertical jump ability in young female football players. A total of 37 licensed female football players competing in the Turkish Women's Second League participated in the study. Participants were randomly assigned to an experimental group (n = 20) or a control group (n = 17). The study evaluates whether this integrated training approach enhances acceleration, force production, and neuromuscular control compared to regular team training alone.

The hamstring muscle, as a biarticular muscle, plays a crucial role in both hip extension and knee flexion and is part of the Superficial Back Line, which supports upright posture and prevents excessive flexion. Its continuous postural function requires endurance-oriented muscle fibers and sustained low-level muscle tone. Tightness in the hamstrings is commonly linked to postural imbalances and structural factors, contributing to gait alterations, low back pain, tendinopathy, and other musculoskeletal disorders. Improving hamstring flexibility is important for performance and injury prevention, with myofascial release-particularly self-myofascial release using foam rollers-being an effective method. Foam rolling reduces muscle tension, enhances tissue hydration, and may alleviate fascial adhesions. However, sex differences exist in connective tissue properties, potentially influencing outcomes. Limited research has explored foam rolling's impact on peripheral muscle oxygenation. This study aims to investigate the effect of foam rolling on hamstring muscle oxygen saturation in recreational individuals with tightness, with a hypothesis that females may show greater increases.

The anterior cruciate ligament (ACL) is one of the main stabilizers of the knee, and its injury is among the most common soft tissue injuries of the knee. Surgical reconstruction of the ACL can be performed using various techniques and different types of tissue grafts, including both autografts and allografts. Although ACL reconstruction is a widely performed surgical procedure in young and physically active individuals-typically patients under 30 years of age-to promote return to sports and prevent early onset of osteoarthritic degeneration, the surgical approach has historically been less common in patients over the age of 50. This is largely due to the lower functional demands typically observed in older patients. However, with increasing life expectancy and a corresponding rise in functional demands among older individuals, the surgical approach to ACL reconstruction has been progressively reconsidered in the over-50 population. Several recent studies have aimed to evaluate the outcomes of ACL reconstruction in older adults, showing promising results in terms of both recurrence rates and complication rates. At the II Clinic of the Rizzoli Orthopaedic Institute, under the direction of Professor Zaffagnini, the preferred technique for ACL reconstruction is the "single-bundle over-the-top technique using gracilis and semitendinosus tendons, combined with a lateral extra-articular tenodesis (LET)." LET is an additional surgical step performed alongside ACL reconstruction, which has shown excellent results, especially in young patients at high risk of reinjury. Specifically, clinical data have shown that adding LET to ACL reconstruction can reduce the failure rate by approximately 30%, significantly improve knee stability, and enable a faster return to sports-all without increasing the rate of complications compared to the standard isolated ACL reconstruction technique. Given these encouraging results in terms of safety and reduced failure rates, the combined ACL + LET procedure has historically been used at the Rizzoli Orthopaedic Institute for all patients, including those over 50 years of age. The consistent use of this technique allows for the creation of a homogeneous patient cohort, all treated with the same surgical approach. This also enables the formation of two comparable patient groups-one over 50 and one under 30-both treated with the same technique, allowing for a meaningful comparison of primary and secondary endpoints. While several studies have aimed to compare ACL reconstruction outcomes in older populations with those in younger cohorts, to date, there are no studies in the literature that specifically assess the outcomes and complication rates of ACL reconstruction using the over-the-top technique combined with LET in patients over 50, and compare them with those of younger patients undergoing the same surgical procedure. Given the growing demand for ACL reconstruction in older patients, we believe it is important to evaluate outcomes in patients over 50 and compare them with a younger cohort, to determine whether the over-the-top + LET technique may be a valid therapeutic option not only for young patients but also for older adults. Of particular interest is the assessment of the reduced risk of failure and complication rate of the ACL + LET technique performed in over-50 patients, to determine whether the excellent clinical outcomes observed in younger individuals are also confirmed in an older population.

Muscle strain injuries represent one of the most prevalent injuries in athletes. Despite this high injury prevalence, there is no evidence to support some of the currently used therapeutic strategies. Amongst them, thermal therapies and especially cryotherapy modalities (Ice, Cold water immersion, perfused garments) have been extensively used on soft tissue injuries to reduce pain perception and decrease inflammation. However, recent findings in humans and in animals have reported conflictual results on the effects of cold on muscle regeneration. On the other hand, recent studies in humans suggest that passive heat exposure can impact positively muscle protein synthesis, mitochondrial content and muscle torque in injured, immobilized and healthy participants. Furthermore, preliminary results from our group have shown a faster removal of muscle damages from the muscle and suggest a better muscle regeneration after a localized heat exposure. As such, our preliminary results confirmed that local heating may represent a promising tool to accelerate muscle regeneration. This randomized controlled trial will investigate the therapeutic effect of two thermal interventions (Hot or cold-water immersion) in the management of acute lower limbs muscle injuries. 135 patients will be distributed in a counterbalanced way into 3 groups: Hot, Cold and Control. All the groups will receive the same physiotherapy treatment. The thermal intervention will consist in 10 sessions of either, 60-minute hot water bath (42°C) for the hot group or, 15-minute Cold water bath (12°C) for the cold group realized after the 10 first physiotherapy session. All thermal interventions will be performed after the testing and physiotherapy treatment.

The project consists of studying the differences between neural gliding techniques of the sciatic nerve and passive stretching of the hamstring muscles in football players.
NCT04328155
Sixty healthy individuals will be randomised into four groups. Group I (15 subjects) will be applied hotpacks, Group II (15 subjects) will be applied infrared, Group III will be applied ultrasound to hamstring muscles for 18 sessions 3 times per week and the subjects will do hamstring self stretching exercise 3 times for 15 seconds. Group IV will only do self stretching exercises. Outcome measures are Range of Motion and hamstring flexibility. Measurements will record before and after the end of the treatment.
NCT04440878
The flexibility of the hamstring muscles is very important and many stretching methods are applied on the hamstring muscles for reducing muscle resistance on movement. The objective of this study was to investigate the acute effects of static stretching and the Mulligan traction straight leg raise (TSLR) technique administered to the hamstring muscles on reducing its resistance to movement by using ultrasound elastography in healthy individuals.
NCT03979326
The aim of the work is to assess the effect of the menstrual cycle on the biomechanical properties of the muscles. The study will be conducted among young women aged 20-25 with a regular menstrual cycle. During the test, muscle strength and muscle flexibility as well as activation times will be performed. The study will assess the effect of the stretching of the hamstring muscles on the biomechanical properties of the muscles in the different phases of the menstrual cycle.
