Have you ever thought of your lungs as a muscle group? They technically are not muscles, but they are controlled by muscles and behave similarly. They are made of soft tissues that expand and compress...
Fat Replacement of Paraspinal Muscles with Aging in Healthy Adults
MRI MUSCLE FAT REPLACEMENT PARASPINAL MUSCLE AGING
2018/4/24
Purpose The aims of this study were to investigate the age-related changes in fatty replacement and cross-sectional area (CSA) of cervical, thoracic, and lumbar paraspinal muscles versus leg muscles i...
Predicting the Functional Roles of Knee Joint Muscles from Internal Joint Moments
KNEE JOINT STABILITY MUSCLE ACTIVITY LOWER LIMB KINETICS HEALTHY CONTROLS PARTIAL LEAST SQUARES REGRESSION
2018/4/24
Introduction Knee muscles are commonly labeled as flexors or extensors and aptly stabilize the knee against sagittal plane loads. However, how these muscles stabilize the knee against adduction–abduct...
Oral Rg1 supplementation strengthens antioxidant defense system against exercise-induced oxidative stress in rat skeletal muscles
Ginseng Ginsenoside Antioxidant status
2015/7/23
Previous studies reported divergent results on nutraceutical actions and free radical scavenging
capability of ginseng extracts. Variations in ginsenoside profile of ginseng due to different soil and...
Maximal Voluntary Co-Contraction Training may not Always be Effective for Some Leg Muscles
Voluntary Co-Contraction Training Some Leg Muscles
2015/5/21
Simultaneous voluntary contractions of antagonistic pairs (co- contraction) produce resistive forces that act against each other (Maeo et al., 2013c). It has been reported that a training program in w...
Variations in Neuromuscular Activity of Thigh Muscles During Whole-Body Vibration in Consideration of Different Biomechanical Variables
Vibration training surface electromyography muscle strength muscle tuning
2015/5/18
The intention of this study was to systematically analyze the impact of biomechanical variables in terms of different vibration frequencies, amplitudes and knee angles on quadriceps femoris and hamstr...
Trunk Muscle Activities During Abdominal Bracing: Comparison Among Muscles and Exercises
Static and dynamic exercises electromyogram voluntary co-contraction muscle- and exercise-related differences
2015/5/18
Abdominal bracing is often adopted in fitness and sports conditioning programs. However, there is little information on how muscular activities during the task differ among the muscle groups located i...
The Contribution of "Resting" Body Muscles to the Slow Component of Pulmonary Oxygen Uptake During High-Intensity Cycling
Muscle oxygenation near infrared spectroscopy oxygen uptake kinetics arm exercise
2015/5/13
Oxygen uptake (VO2) kinetics during moderate constant-workrate (WR) exercise (>lactate-threshold (θL)) are well described as exponential. AboveθL, these kinetics are more complex, consequent to the de...
Effect of Creatine Supplementation on Muscle Damage and Repair Following Eccentrically-Induced Damage to the Elbow Flexor Muscles
Creatine loading muscle damage muscle force muscle soreness
2015/5/13
We investigated effects of creatine (Cr) supplementation (CrS) on exercise-induced muscle damage. Untrained males and females (N = 27) ages 18-25, with no CrS history in the past 4 months, were random...
Effect of Pressure Intensity of Compression Short-Tight on Fatigue of Thigh Muscles

2017/5/25
Existing studies have failed to provide evidence of a positive effect on exercise performance by wearing compression short tights covering only both thighs. This could be due to an inadequate pressure...
Neuromotor Control of Gluteal Muscles in Runners with Achilles Tendinopathy
ELECTROMYOGRAPHY GLUTEUS MEDIUS GLUTEUS MAXIMUS GAIT
2017/5/19
The purpose of this study was to compare the neuromotor control of the gluteus medius (GMED) and gluteus maximus (GMAX) muscles in runners with Achilles tendinopathy to that of healthy controls.
