THE EFFECTS OF INITIAL HIP ABDUCTION AND EXTERNAL ROTATION STRENGTH AND NEUROMUSCULAR FATIGUE OF THE GLUTEUS MEDIUS ON THE STAR EXCURSION BALANCE TEST IN MALE AND FEMALE HEALTHY SUBJECTS
The gluteus medius muscle is an essential hip stabilizer during unilateral stance. A weakened or fatigued gluteus medius may be associated with decreases in postural control during dynamic balance. The objective of this study was to determine if initial hip muscular strength and gender affect …

Effects of beta-hydroxy beta-methylbutyrate (HMB) supplementation on gluteus medius muscle fiber composition and muscle performance in adult Thoroughbred horses exercising to fatigue on a high-speed treadmill
… completing a standardized exercise test (SET). Gluteus medius (GM) muscle samples were obtained before the SET for fiber-typing and venous blood was collected before and immediately upon completion of the SET for lactate measurements. Heart rate (HR), biceps femoris (BF) and semitendinosus (ST) …

Do the gluteal muscles influence dynamic knee valgus when single-leg landing?
… ligament ACL injury. Gluteal muscles especially gluteus maximus and medius are believed to have a role in controlling hip motion that is associated with dynamic knee valgus. Landing onto one leg is a common scenario of ACL injury mechanism and would appear to require considerable Gluteal muscle …

Changes in spinal posture, muscle activation, center of pressure and discomfort while standing with different footrest heights during a standardized computer task
… lumbo-sacral angle, lumbar-to-thigh angles, gluteus medius and lumbar erector spinae muscle activity, and COPrange in the elevated limb. Discomfort increased over the 15 minute trial regardless of condition. The medium (20cm) footrest provided unique advantages over the other footrest heights …

Organization of energy transfer and feedback regulation in oxidative muscle cells
… exist also in human heart atrium and in musculus gluteus medius (MGM), 4) to investigate whether these units may in MGM disintegrate during osteoarthritis. Results of the study: Differently from cardiomyocytes, where mitochondria and CaMgATPases are organized into ICEUs which ensure effective …

Towards understanding EC coupling protein expression with age
… knee (vastus medialis) and hip replacements (gluteus minimus and gluteus medius). The levels of ASI splice variant transcripts in the muscle were investigated using RT-PCR. Furthermore, the effect of the addition of beta1a to recombinant ASI splice variant channels in lipid bilayers was …

Frontal Plane Pelvic Drop in Runners: Causes and Clinical Implications
… current focus of these patients' treatment is gluteus medius muscle (GM) strengthening and gait retraining, with the goal of decreasing frontal plane pelvic drop. Unfortunately, there is a research void assessing the role of GM function on pelvic drop, and the effect of an increased pelvic drop …

Regulation of satellite cells by extrinsic factors during recovery from exercise in horses
… equine SCs (eqSCs) were isolated from the gluteus medius of mature thoroughbred geldings for activation, proliferation and differentiation assays. Activation was not accelerated by 1, 5, 10, or 25 ng/mL HGF. Instead, 25 ng/mL HGF increased the proliferation rate of eqSC via protein kinase C …

Differences in Balance and Muscle Activation Strategies during Gait Initiation at Different Speeds between Young and Middle-Aged Adults
… surface electromyography (EMG) signals of the gluteus medius (GM), adductors (ADD), tibialis anterior (TA) and medial gastrocnemius (MG) recorded while initiating three steps forward while walking on a GAITRite® platinum mat at a normal self-selected and fast walking speed for 10 trials each. …

A Comparison of Neuromuscular Control between Subjects with and without Chronic Ankle Instability
… (COP), and integrated EMG activation of the gluteus medius (Gmed), gluteus maximus (Gmax), tibialis anterior (TA), and peroneus longus (PL) during each reach direction of the SEBT. Results: There was a significant difference in mean outcome measures between the three study groups. When …

Electromyographical Analysis of and Medial-Lateral Anticipatory Postural Adjustments prior to Stepping and Single Leg Reaching in Chronic Unstable Ankles
… activation of the dynamic restraints at the hip (gluteus medius-GM, adductor magnus-AM), and at the ankle, (tibialis anterior-TA, peroneus longus-PL), in individuals with CAI. Therefore, the purpose of this study was to examine lower leg preparatory electromyographic (EMG) muscular activity (EMG …

Establishing Normal Motion Between the Thigh to Pelvis and Trunk to Pelvis Segments in Female, Collegiate Volleyball and Soccer Athletes
… complex we determined the normal gluteus medius lurch for normal female collegiate athletes was 6.88°, so anything greater than this can be determined abnormal or pathological. Future research projects could analyze the muscle activation that is causing the motions of the thigh to …

Revealing complexities within flat-water kayaking: injury prevention and biomechanical analysis
… during a maximal 200 metre time trial. Gluteus medius, lower trapezius and erector spinae were measured for the first time in maximal kayaking. The latissimus dorsi, pectoralis major and external oblique muscles were more active during the contralateral phase than has previously been …

Nutrient analysis of the beef alternative merchandising cuts
… 44.92, 46.04, and 3.04%, respectively. The Gluteus medius contained the highest percentage of polyunsaturated fats regardless of Quality Grade. Of the fatty acids detected, oleic, palmitic, and stearic acids represented 74.56% of the fatty acid profile of all BAM cuts. Trans fats totaled …

The effects of the lumbopelvic manipulation on the fatigability of the back and hip muscles in adults with chronic low back pain
… level of the lumbar multifidus (MULT), gluteus maximus (GMAX) and gluteus medius (GMED) muscles in addition to the pain level as compared to a placebo intervention in patients with CLBP. Thirty-one participants with CLBP, 30.2 ±10.1 years of age, completed the immediate effect part of …

Needle Length Required for Intramuscular Injection in Women
… intramuscular injection sites: (1) deltoid, (2) gluteus maximus, (3) gluteus medius, and (4) lateral femoral. Pearson product-moment correlations and regression lines were computed for each of the variables. Data from the study were compared with two body measurement studies of 22,000 and 10,042 …
