The effect of amino acid supplementation on weight, body composition, muscle size, and muscle strength in amateur weightlifters
… the effect of an amino acid supplement on muscle size, muscle strength, body composition, and body weight. A blind protocol was followed in which eight of the participants were administered the amino acid supplement and seven received a placebo. Each subject was tested before and …

The mechanics of patello-femoral joint dysfunction: the usefulness of the Q-angle
… in which the vastus medialis oblique (VMO) muscle is ineffective in controlling patellar position but this is based on assumption. The Q-angle, a frontal plane measure, indicates patellar position relative to the pelvis and tibia; however, there is no standardised measurement protocol and it …

Sarcopenia and cognitive ageing: investigating their interrelationship, biological correlates and the role of glucocorticoids
… of an image analysis technique to measure neck muscle size on volumetric MR brain scans; the subsequent use of the technique in elderly cohort studies; statistical modelling to investigate the role of glucocorticoids in sarcopenia; and an invasive clinical study to develop a novel technique to …

Muscle-specific considerations for aging human skeletal muscle
… that the age-associated change in skeletal muscle mass is muscle specific, yet the number of specific muscles that have been studied to form our understanding in this area is limited. In addition, few aging investigations have examined multiple muscles in the same individuals. This …

The effects of osteoarthritis, acute voluntary inactivity and injury on skeletal muscle function, Na+, K+ -ATPase content and isoform abundance
… substantial maladaptions in each of skeletal muscle size, strength and endurance. In skeletal muscle the Na+, K+ -ATPase (NKA) enzyme is pivotal in the regulation of Na+ and K+ concentrations across the sarcolemmal and t-tubule membranes and hence in the maintenance of muscle excitability. The …

The effect of dietary creatine supplementation on compensatory muscle hypertrophy and performance characteristics of specific fiber types
… and electrically stimulated performance of those muscles. Thirty-six rats were divided evenly into six groups. Two groups were surgical controls, two groups had the tibialis anterior ablated, to hypertrophy the extensor digitorum longus (EDL), and two groups the gastrocnemius and the plantaris …

Dynamic Upper Leg Strength and Neuromuscular Function in Children, Adolescents and Adults
This study examined muscle strength, muscle performance, and neuromuscular function during contractions at different velocities across maturation stages and between sexes. Participants included pre-pubertal, late-pubertal and adult males and females. All completed 8 isometric and 8 isokinetic leg …

Muscle strength and activation characteristics of power- trained and non-athlete boys and men
During maturation, muscle strength is enhanced through muscle growth, although neuro-muscular factors are also believed to be involved. In adults, training for power sports has been shown to enhance muscle strength and activation. The purpose of this study was to examine muscle strength and …

Examining the Effects of Deer Antler Velvet Supplementation on Muscular Strength, Performance, and Markers of Delayed Onset Muscle Soreness.
… performance, and markers of delayed onset muscle soreness following a 10-week resistance training period.</p> <p><strong>Participants:</strong> 16 resistance-trained males (18-35) volunteered.</p> <p><strong>Measures:</strong> DEXA, 1-RM, a power test, and a 70% performance trial were …

Assessment of Electrode Configurations of Electrical Impedance Myography for the Evaluation of Neuromuscular Diseases
… significantly on subcutaneous fat thickness, muscle size and inter electrode distance. The objective of this research is to find an electrode configuration which can minimize the effects on EIM parameters due to subcutaneous fat thickness variation. In this study, a model of human upper arm …

THE HUMAN POPULATION IS AGING: HOME-BASED EXERCISE AND AMINO ACIDS SUPPLEMENTATION TO COUNTERACT THE LOSS OF MUSCLE MASS AND MUSCLE STRENGTH IN OLDER PEOPLE.
… the association between lower limb strength, muscle mass and composition, and balance ability in elders. Thirthy-four older participants (Age: 65.6 ± 4.73 years; male = 10 and female = 24) were assessed for muscle strength (maximal isometric strength of knee extensors and one repetition …

The Effect of Protein Blend Supplementation and Resistance Exercise on Skeletal Muscle Growth and Adaptation
… efficacy of a new protein supplement to improve muscle growth and strength when ingested following exercise. The hypothesis is that novel supplementation of mixed dietary proteins (protein “blend”) with different amino acid release profiles will prolong amino acid levels in the blood leading to …

The role of acute ambient hypoxia in the regulation of myostatin
… or environmental causes humans show muscle atrophy, challenging homeostasis and increasing mortality rate. Chronic hypoxia also presents with elevated myostatin peptide, a negative regulator of muscle size. This work induced acute hypoxia in healthy individuals; hypothesizing hypoxia …

The Effect of Training Volume and Intensity on Improvements in Muscular Strength and Size in Resistance-trained Men
… of improvements in muscular strength and size are influenced by the volume and intensity of a resistance training program. While it is clearly advantageous for resistance-trained individuals to utilize programming specific to these goals, it not clear which is more important. Therefore the …

Do Individual Responses to Resistance Exercise Exist to an Extent That Can be Detected Beyond That of Measurement Error/Random Biological Variability?
… group also increased ultrasound measured muscle size at all sites (all>0.22cm), each of which were greater than both the control and 1RM group (p<0.05). The 1RM group did not increase muscle mass (p>0.05). Across both training groups, the only individual responses were found in the change …

The Acute and Chronic Muscle Adaptations Following six weeks of "No Load" and Traditional High Load Resistance Training
Muscle growth is postulated to occur through mechanisms initiated by local muscle tension. This appears to be true, independent of the external load, provided sufficient tension is achieved. PURPOSE: The purpose of this study was to remove the influence of an external load and compare the acute and …

The influence of two physical activity programs on bone and muscle health in youth with cerebral palsy and other neuromotor impairments.
… rapidly. During this time, physical activity, muscle-bone interactions, and gravity help stimulate bone development. However, in conditions that limit mobility, such as cerebral palsy (CP) and other non-progressive neuromotor impairments (CP-like), physical activity is reduced, which can lead …
