An Autopsy Case of CD4-Positive Lymphoproliferative Disorder at 38 Years Post-Transplantation Presenting With Cardiac Invasion and Cerebral Infarctions Open
Lymphoma is a rare but life-threatening complication following solid organ transplantation. The vast majority of these lymphomas arise from B cells associated with Epstein-Barr virus (EBV), and a small number of cases have a T-cell origin.…

Respiratory regulation and lung volume during aquatic and land‐based exercise in healthy Young adults Open
Elevated hydrostatic pressure during water immersion reduces lung volume and compliance at rest. These alterations may persist during exercise, influencing both the respiratory regulation and lung volume. This study compared respiratory re…

Characterizing link among phase angle, muscle strength, body composition variables, and urine metabolites in Japanese females with or without dysmenorrhea: A pilot study Open
The study findings highlight distinct associations among body composition, PhA, muscle strength, and urinary metabolites in these female groups. However, the study is limited by the absence of severity of dysmenorrhea symptoms, phases of m…

Exploring the association between bioelectrical impedance parameters and body composition in women with and without dysmenorrhea and postmenopause Open
Female reproductive status influences body composition, including fat mass (FM), fat‐free mass (FFM), and bone health. We aimed to examine differences in body composition, bone health, and bioelectrical impedance analysis (BIA) parameters,…

Cardiac baroreflex sensitivity during repeated handgrip exercise: Comparisons with sit‐stand maneuvers and spontaneous rest Open
The cardiac baroreflex regulates arterial pressure via autonomic heart rate control. While sit‐stand maneuvers (SSM) have been used to assess baroreflex sensitivity (BRS), they may be impractical for physically immobile individuals. This s…

Effectiveness Index of Mechanical Energy Utilization in Male 400‐m Sprinters and the Relation Between Muscle Cross‐Sectional Area of the Trunk and the Lower Limb Open
The purpose of this study was to identify the morphological characteristics of trunk and lower limb muscles associated with 400‐m sprint performance and “effectiveness index of mechanical energy utilization (EI).” Twelve male 400‐m sprinte…

Evaluation of Energy Balance Estimated From Total Energy Expenditure and Body Composition Changes in Junior Sumo Wrestlers: An Observational Study Over Six Months Open
Background Sumo is a sport that requires wrestlers to develop their physique from childhood for athletic advantage. However, the energy expenditure and energy balance required for the growth of junior Sumo wrestlers remain unclear. This st…

Glycated hemoglobin (<span>HbA1c</span>) is independently associated with the bioelectrical impedance phase angle in junior sumo wrestlers: A pilot study Open
The study explores the relationship between phase angle (PhA), an indicator of cellular health, and metabolic health parameters among junior sumo wrestlers in Japan. Given the demanding lifestyle and high‐energy diets of sumo wrestlers tha…

Consideration on size, velocity and path of droplets emitted during running Open
Velocity and path of large droplets can be expressed by the theoretical solution of particles in downfall motion under air resistance. We therefore conclude that wearing a mask while running gives adverse effects in preventing infection. P…

Differences in the prefrontal cortex responses of healthy young men performing either water-based or land-based exercise at light to moderate intensity Open
Cerebral blood flow increases more during water-based exercise than land-based exercise owing to the effects of end-tidal CO 2 (PETCO 2 ) and mean arterial pressure (MAP) changes due to water immersion. However, it is unclear whether oxyge…

Effect of aquatic walking on prefrontal activity and executive function in healthy middle- and old-aged adults: a pilot study Open
Previous studies have shown that normal and complex land walking (e.g. dual-task and obstacle walk) have a positive effect on the prefrontal cortex (PFC) and executive function. However, little is known about the benefits of aquatic walkin…

Respiratory function and breathing response to water‐ and land‐based cycling at the matched oxygen uptake Open
The impact of underwater exercise on respiratory function remains unclear when its metabolic rate is matched with exercise performed on land. Therefore, we compared the breathing responses and respiratory function during and after water (W…

Variabilities of salivary human herpesvirus 6/7 and cortisol levels during a three-day training camp in judo athletes Open
Physical fatigue accompanying athletic training has been a problem for ages. While salivary cortisol has traditionally been used to assess physical stressors, salivary human herpesvirus 6 and/or 7 (HHV-6/7) have recently been presented as …
