Hyun-Seung Rhyu, Hyun-Gu Han, Soung-Yob Rhi
Although many studies have focused on stretching techniques for athletes, no comprehensive studies have investigated the use of the instrument-assisted soft tissue mobilization (IASTM) technique in young basketball players. The active properties of muscle and subjective reporting of functional ability were used to identify the effects of IASTM on the calf muscle. Active range of motion (AROM), functional fitness, and isokinetic lower strength in the knees and ankles were measured in 40 healthy young basketball players...

INTRODUCTION: Neurodegenerative disease is one of the main contributing factors affecting muscle atrophy. However, this intriguing brain-muscle axis has been explained by the unsubstantial mechanisms. Although there have been several studies that have evaluated the muscle profile and its relation to cognition in patients with dementia, there is still lack of data using standardized methods and only few published studies on Korean populations. The objective of this study is to evaluate the relationship of muscle mass and strength to cognition in patients with Alzheimer's disease dementia (AD)...

Background: The percentage of sustained maximal oxygen uptake and the running economy are important factors that determine the running success of endurance athletes. Running economy is defined as the oxygen uptake required to run at a given speed and depends on metabolic, cardiorespiratory, biomechanical, neuromuscular, and anthropometric factors. With regard to anthropometric characteristics, total body mass seems to be a crucial factor for the running economy. Moreover, neuromuscular components, especially knee muscular strength and the strength balance ratio, also seem to be critical for the running economy...

BACKGROUND: Hamstring shortness is the most common musculoskeletal condition in sports athletes, which often contributes to hamstring strain injury. To effectively mitigate the hamstring shortness, contemporary HR, SCS, and IASTM soft tissue techniques have been used. The best practical evidence about the therapeutic effects and the biomechanical mechanisms underpinning these manual techniques remain unknown. OBJECTIVE: The purpose of this study was to compare the effects of HR, SCS, and IASTM techniques on improving hamstring and quadriceps muscle strength, related ratio, knee joint passive stiffness, and pain threshold...

Background: Cam-type femoroacetabular impingement (FAI) is a femoral head-neck deformity that causes abnormal contact between the femoral head and acetabular rim, leading to pain. However, some individuals with the deformity do not experience pain and are referred to as having a femoroacetabular deformity (FAD). To date, only a few studies have examined muscle activity in patients with FAI, which were limited to gait, isometric and isokinetic hip flexion, and extension tasks. Purpose: To compare (1) hip muscle strength during isometric contraction and (2) lower limb kinematics and muscle activity of patients with FAI and FAD participants with body mass index-matched healthy controls during a deep squat task...

INTRODUCTION: Vitamin D deficiency is a common health problem. Vitamin D supplements are used to improve vitamin D status; however, there are contradictory data related to what doses to give and how often they should be given. Many studies have investigated the effects of vitamin D supplementation on muscle strength, but the results remain controversial. We aimed to compare the effects and safety of single high-dose with daily low-dose oral colecalciferol on 25(OH)D levels and muscle strength in postmenopausal women with vitamin D deficiency or insufficiency...

Background Stroke represents the largest cause of chronic disability resulting in muscle weakness and instability in the trunk muscles. Despite the reliable measures from isokinetic devices for upper/lower limb muscles, there is a lack of measures for trunk muscles in post-stroke hemiparesis. Objectives To investigate the reliability of the strength and endurance measures from an isokinetic dynamometer for able-bodied and post-stroke hemiparesis people. Methods The measures were taken from both groups (control/hemiparesis) performing antagonistic movements (flexion/extension) during different protocols (seated-compressed and semi-standing) to assess strength (60º/s) and endurance (120º/s)...

Isokinetic hamstring-to-quadriceps (H:Q) ratios are frequently used to assess knee muscle strength imbalances and risk of injuries/re-injuries. The use of peak torque (PT) or total work (TW) to estimate joint stability may lead to different results because of the differences between these two neuromuscular variables. Thus, the current study aimed to compare the conventional and functional H:Q ratios calculated by PT and TW. Ninety-three male professional soccer players from Brazilian first division teams performed isokinetic concentric and eccentric contractions of the quadriceps and the hamstrings at 60°/s...
