Hamstring/quadriceps strength ratios: An analysis and a strength training study
This study was performed to examine the hamstring:quadriceps (H:Q) ratios of female soccer athletes, and to test the effects of a six week strength training program on these ratios. Twelve NCAA Division I female soccer athletes volunteered for this study. Subjects completed two practice sessions, a …

The Relationship Between the Hamstrings to Quadriceps Strength Ratio and Anterior Cruciate Ligament Forces
… (OA). Forces developed by the hamstrings and quadriceps have been found to decrease and increase forces on the ACL, respectively. Thus, some believe that the ratio of the strengths of these muscles groups (the H:Q strength ratio) is relevant when discussing ACL forces; a low H:Q ratio …

EFFECTS OF BEETROOT JUICE, PROTEIN SUPPLEMENTATION, AND RESISTANCE TRAINING ON STRENGTH IN OLDER ADULTS
Reductions in muscle strength, lean body mass, and insulin sensitivity occur with aging; a novel intervention of dietary nitrates, protein supplement, and resistance training was tested to improve these age-related declines. Beetroot juice is a dietary source high in nitrates. PURPOSE: The primary …

Ultrasound Guided Motor Sparing Knee Blocks for Postoperative Analgesia Following Total Knee Arthroplasty
… hours. No significant differences were found in quadriceps strength, functional outcomes, side effects, satisfaction, or length of stay between groups. The MSB provided longer analgesia than the PAI while not negatively affecting quadriceps strength, length of stay, or functional rehabilitation.

Changes in Neuromuscular Performance Throughout the Menstrual Cycle in Physically Active Females
… Along with blood measurements, isokinetic quadriceps strength at 60°/sec, 180°/sec, and 300°/sec, and knee joint laxity were measured at each visit. Main Outcome Measures: Isokinetic quadriceps strength, KT- 1000 measurements, blood assays. Results: Isokinetic peak torque at 60°/sec was …

Whole-Body Vibration Compared to Traditional Physical Therapy in Individuals with Total Knee Arthroplasty
… treatment during TKA rehabilitation to increase quadriceps strength and function, and 2) to investigate the effect of WBV on quadriceps voluntary muscle activation. Subject and Methods. Individuals post TKA (WBV n=8, control n=8) received physical therapy with and without WBV for four weeks. …

Muscle Dynamics as the Result of Whole Body Vibration and Plyometrics
… are common training techniques which increase strength, blood flow, force and power. The effects these techniques have on sedentary population is unknown. It is our aim to assess the effectiveness of WBV and plyometrics on sedentary population. SUBJECTS: Three groups of nine sedentary subjects …

Cortico-motor adaptations and proprioceptive acuity in patients with unilateral anterior cruciate ligament deficiency
… participated. Subjective function (KOS-ADLS) and quadriceps strength (MVC) were measured. Proprioceptive acuity was assessed with a weight discrimination task. Transcranial magnetic stimulation was used to assess four indices of cortico-motor excitability and the quadriceps H-reflex was measured. …

FUNCTIONAL HAMSTRING: QUADRICEPS RATIO AND HAMSTRING INJURY INCIDENCE IN TRACK AND FIELD ATHLETES
… and competition. Functional hamstring to quadriceps strength ratio was measured to study muscular imbalances in these athletes. The hypotheses were: 1) Athletes with previous hamstring injuries have a greater chance of subsequent hamstring injury whether or not they have a functional ratio …

Sarcopenia and cognitive ageing: investigating their interrelationship, biological correlates and the role of glucocorticoids
… brain structure and muscle function, mostly grip strength and gait speed; and cognition and muscle function. However, I found no relationship between current cognition and muscle size in any of the above studies. Cortisol was identified as a possible explanatory factor in the relationship between …

The Severity of Obesity and Knee Osteoarthritis: Effects on Strength and Gait
… Internal knee moments, knee joint forces, and quadriceps and compressive forces were calculated using 3-D gait analysis with a 37-reflective marker set arranged in a Cleveland Clinic full-body configuration, a 6-Camera Motion Analysis System set to sample data at 60 Hz, and a torque-driven …

Transcranial Direct Current Stimulation with Individualized Physical Therapy for Chronic Knee Pain
… with pressure pain threshold testing, and quadriceps strength as compared to the sham group. The treatment paradigm was found to be acceptable to both individuals with chronic knee pain and physical therapists. Conclusion: The study findings demonstrate that tDCS combined with …

Age Related Differences in Motor Output Variability During Isometric, Concentric and Eccentric Quadriceps Femoris Muscle Contractions
… and discrete eccentric contractions of the quadriceps femoris. Of particular interest was to model variability of force during continuous and discrete isometric contractions. Participants were 24 young (25.3 +/- 2.8 years) and 24 elderly individuals (73.3 +/- 5.5 years) that were active, …

The role of muscle dysfunction in patellofemoral pain : influence of different treatment approaches
… that the majority of studies analysed muscle strength or muscular activity. Whereas, muscular dysfunctional factors such as atrophy, muscular inhibition, fatigue and flexibility remained understudied in individuals with PFP. To develop a robust and reliable test protocol for the investigation …

Eccentric cycling rehabilitation after anterior cruciate ligament reconstruction: a randomised controlled trial of strength and biomechanical outcomes
… ligament reconstruction (ACL-R), persistent strength and biomechanical deviations remain. Reducing these by training may reduce risk of re-injury or osteoarthritis for these patients. A cross-sectional study investigated biomechanics of ACL-R male patients long-term (~5 years) post surgery. …

Characterization of Quadriceps Neuromuscular Function in Knee Osteoarthritis
… The purpose of this thesis was to characterize quadriceps neuromuscular dysfunction in patients with knee osteoarthritis (OA). Concerns pertaining to study design in this patient population (e.g. disease severity criteria and muscle imaging outcome measures) were also addressed. METHODS: Five …

Strength and power assessment in rehabilitation: profiling the athlete’s return to sport journey following ACL reconstruction
… The aim of the proposed research was to examine strength and power in the rehabilitation pathway of soccer players following ACL reconstruction. This enabled us to explore interrelationships between physical capacities, movement strategies, and subsequent injury risk. These data were also …
