The balance of mental, physical, and technical aspects is essential in improving ballet performance. Ballet dancers’ emotional and behavioral characteristics vary, even under identical stress conditions. This study aimed to investigate the association between the pain candidate genes 5-HTTLPR and COMT and anxiety in Japanese ballet dancers. Partici...

Ocular motility has been linked to Sports Concussion Assessment Tool 5 scores. However, the link between ocular motility changes and assessment result changes remains unclear. Hence, we investigated that potential link in patients with sports-related concussions. We retrospectively included participants aged≥18 years who were diagnosed with a sport...

Introduction Professional dancers are committed to dancing despite their injuries and mood changes. Therefore, dancers’ balance ability should be evaluated as an objective indicator of the quality of their dance/dancing ability. Objective We aimed to examine the relationship between the balance ability of professional ballet dancers and their psyc...

Ballet dancers are at a higher risk of injury if they are anxious before a public performance. The association between psychological elements and a medical approach to injury prevention for adolescent ballet dancers in Japan was studied in this study. We conducted a prospective study of psychological factors and injury, based on the stress-injury m...

Mechanical stress is an important factor affecting bone tissue homeostasis. We focused on the interactions among mechanical stress, glucose uptake via glucose transporter 1 (Glut1), and the cellular energy sensor sirtuin 1 (SIRT1) in osteoblast energy metabolism, since it has been recognized that SIRT1, an NAD+-dependent deacetylase, may function a...

Exercise increases oxidative stress, leading the body to strengthen its antioxidant defenses, thus reducing the incidence of major diseases. As these associations are relatively unclear for ordinary levels of exercise for reduced stress, this study evaluated the effects of different exercise conditions on diacron-reactive oxygen metabolites (d-ROMs...

Purpose We previously created a self-assembled cartilage-like complex in vitro from only three cartilage components, hyaluronic acid (HA), aggrecan (AG) and type II collagen, without other materials such as cross-linking agents. Based on this self-organized AG/HA/collagen complex, we have created three novel types of biphasic cartilage and bone-lik...

We investigated, in an animal model of skeletal muscle injury, whether microcurrent electrical neuromuscular stimulation (MENS) and hyperbaric oxygen (HBO) therapy used in combination (MENS and HBO) enhances the restorative benefits conferred by these treatments alone. Skeletal muscle injury was simulated in 40 7-week-old male C57BL/6J mice by inje...

The purpose of this study was to investigate the long-term effects of anterior cruciate ligament (ACL) resection on the morphological and contractile characteristics of rectus femoris (RF) and semimembranosus (SM) muscles in both injured and contralateral hindlimbs in rats. Wistar male rats (8-week old) were used. Rats were divided into two groups;...

Objectives: Exercise-induced bronchoconstriction (EIB) is a transient acute airway narrowing that occurs as a result of exercise. Approximately 80% of individuals with asthma experience exercise-related symptoms (ERS). The prevalence of EIB in the general population without a known asthma diagnosis has been estimated to be approximately 5%–20%, but...

Aging is one of the major pathologic factors associated with osteoarthritis (OA). Recently, numerous reports have demonstrated the impact of sirtuin-1 (Sirt1), which is the NAD-dependent deacetylase, on human aging. It has been demonstrated that Sirt1 induces osteogenic and chondrogenic differentiation of mesenchymal stem cells. However, the role o...

The purpose of this study is to examine the effect of knee bracing on static and dynamic balance (postural stability).Two knee braces were examined: soft type (A, “Short Runner Airmesh”) and hard type (B, “Townsend-Rebel TM5”). For thirteen collegiate American football players, three conditions – no bracing (Group N), attached brace A (Group A), an...

Objective: Cold therapy, so-called icing, is often used immediately after muscle injuries as first aid for the suppression of inflammation and pain relief. Recent evidences show icing retards the regeneration of injured skeletal muscle. On the other hand, microcurrent electrical neuromuscular stimulation (MENS) promotes the regeneration of injured...

Effects of neuroticism on partial and whole body reaction times were investigated under stress, or choking conditions in student participants (N = 127). We measured simple and choice reaction times of parts of the body and choice reaction times of the whole body in the participants with high and low neuroticism such as depression, cyclic tendency,...

Ballet dancers’ risk of injury is high if their state anxiety is high before a public performance. This research investigated the relationship between psychological factors and a medical approach to injury prevention for adolescent ballet dancers in Japan. Participants were 44 elite adolescent ballet dancers (41 females, 3 males, age range 18.0-21...

To investigate the incidence of acute injuries and soccer-related chronic pain from long-term training and during matches in adolescent players using natural grass turfs (NT) and artificial turfs (AT). Case-controlled prospective study. Institutional-level Fédération Internationale de Football Association Medical Centre of Excellence. Youth soccer...
