Acute arterial stiffening occurs during postprandial hyperglycemia. Such vascular responses are suggested to be averted by suppressing the glycemic response. We previously developed an α-glucosidase-inhibiting tea powder from leaves of Morus australis (M. australis), a mulberry species distributed in Ryukyu Islands, and demonstrated that this has inhibitory effect on blood glucose elevation after sucrose ingestion. This study aimed investigate powdered M. leaf intake stiffness response In...
Abstract Contrary to cardiovascular risk reductions by aerobic exercise, arterial stiffness, as assessed brachial‐ankle pulse wave velocity (PWV), is higher in swimmers and controls than other aerobically trained individuals. The main muscles actively recruited swimming are the upper limbs, so this study aimed investigate heart‐brachial PWV compare stiffness indices between modes measurement localities. Subjects comprised 60 individuals (18–22 years), including 20 untrained (Con), cyclists...
Persistent stressful situations can have detrimental cardiovascular effects; however, effects on the blood pressure (BP) response to exercise not been fully examined. This study investigated impact of a 2-week situation pressor response. Eight healthy male university paramedic trainees underwent hospital training and control period study. Pre- post-intervention, BP responses test (2-min submaximal isometric handgrip [IHG] followed by post-exercise muscle ischemia [PEMI]) cold (CPT) were...
Abstract Background To prevent inflammatory side effects early in the titration phase of clozapine, international guidelines recommend measuring clozapine blood levels weekly. However, data on such measurements are lacking. Methods We retrospectively reviewed medical records all patients with schizophrenia who were treated for first time and whose measured at least 2 consecutive weeks from initiation our institution 2020 to 2024. Patients divided into groups based whether they had a fever...
Objective: This study examined the relationship between neighborhood food and physical activity environment, obesity among elementary junior high school students in Japan. Methods: The participants were fifth- to ninth-grade children (n=7277), who attending municipal schools Percent overweight (POW) was calculated using their age, gender, height, weight, which collected through a questionnaire. A POW of < 20% considered non-obese, while ≥ obese. Furthermore, geographic information system,...
Abstract The aim of this study was to examine the acute effects low-intensity one-legged electrical muscle stimulation (EMS) for skeletal on arterial stiffness in EMS and non-EMS legs. Eighteen healthy subjects received two different protocols (Control (CT) Experimental (ET) trials) random order separate days. applied left lower limb at 4 Hz 20 min an intensity corresponding elevation pulse rate approximately 15 beats/min (10.9 ± 5.1% heart reserve). Before after experiment, parameters...
Few studies have shown that relatively younger children and adolescents (those born later in the same school year) were less likely to engage physical activity a phenomenon termed relative age effect. Although these mainly targeted elementary middle students, no study has reported on effect ordinary high students. Moreover, sedentary behavior might show an opposite association with activity. Therefore, we aimed clarify effects across different stages Japanese adolescents.
It has been reported that exercise under hypoxic conditions induces reduced muscle oxygenation, which could be related to enhanced activity on electromyography (EMG). Although it demonstrated of voluntary hypoventilation (VH) evokes deoxygenation, is unclear whether VH during impacts EMG. Seven men performed bicycle for 5 min at 65 % peak oxygen uptake with normal breathing (NB) and VH. Muscle oxygenation; concentration changes in oxyhemoglobin (Oxy-Hb), deoxyhemoglobin (Deoxy-Hb) total...
Abstract Background Relative age effect is defined as a phenomenon where children born early generally perform better than later in the same cohort. Physical activity an important factor that might be influenced by relative effect. Socioeconomic factors (e.g., parent’s income, education level) are also associated with adolescent’s physical activity. However, no existing study has examined whether socioeconomic moderate on This aims to clarify and how birth month relate organized sports among...
本研究では，我々が開発したシマグワ葉パウダーの血糖値上昇抑制効果を明らかにすることを目的とした．実験の結果，シマグワ葉パウダーは，その製造過程において，1-DNJ含有量は低下，スクラーゼに対するIC50 値は増加するものの，スクラーゼ阻害活性を保持していることが示された．また，同パウダーを摂取することで，スクロース負荷後の血糖値上昇を抑制でき，それに伴い，インスリン分泌を節減できることが示唆された．本研究から，シマグワ葉パウダーの血糖値上昇抑制効果が明らかとなった．
This study examined whether the point of accelerated deoxygenation active muscle occurs during 20-m shuttle run test (20mSRT) and, if so, it is associated with exercise performance in test. Twenty-nine male subjects performed 20mSRT, and concentration changes oxyhaemoglobin (ΔOxy-Hb) deoxyhaemoglobin (ΔDeoxy-Hb) m. vastus lateralis were measured using a portable near-infrared spectroscopy device. The difference between relative ΔOxy-Hb ΔDeoxy-Hb (Δ[Oxy-Hb - Deoxy-Hb]) was regarded as...

Purpose: Acute (immediate) or regular (mid- long-term) stretching increases arterial compliance and reduces stiffness. Stretching is widely known to induce functional factor changes, but it unclear whether alters structural factors. Ultrasound shear wave elastography can quantify the distribution of tissue elastic properties as an index This study thus aimed examine effects acute cervical on wall properties. Methods: Seventeen healthy young adults participated in two different trials for 15...
The present study investigated the inhibitory effect of bread containing powdered Morus australis leaves on postprandial elevation blood glucose level. First, we assessed 1-deoxynojirimycin (1-DNJ) content and α-amylase- maltase-inhibitory activities M. leaves. Second, this in healthy individuals. Although level 1-DNJ was reduced during bread-making process, still exhibited no α-amylase-inhibitory activity. median concentration higher than alone, retained its Moreover, consumption suppressed...
A survey was conducted to assess physical activity, depression, and sense of coherence among early adolescents. This study used a cross-sectional sample 12,086 students (G5-G9) from 28 public elementary schools 22 junior-high-schools in Japan. total 9,424 (G5-G8) were surveyed December 2013 2015 using the International Physical Activity Questionnaire (IPAQ) -short form measure activity (PA), Depression Self-Rating Scale for Children (DSRSC) depressive symptoms, Sense Coherence Scale-13-item...
Abstract Objective: Acute mental stress (MS) increases arm blood pressure (BP); however, it remains unclear whether the stress-induced pressor response is also seen in other vessels. The present study aimed to examine impact of acute MS on ankle BP. Fifty-six young, healthy men (age range, 19–24 years) were divided into (n = 29) and control (CON) 27) groups, each group performed a 5-min (mental arithmetic) or CON tasks. Systolic diastolic BPs (SBP DBP, respectively) both brachial posterior...
Acute mental stress (MS) induces a transient increase in arterial stiffness. We verified whether single bout of bench step (BS) exercise for 3 minutes counteracts acute MS-induced stiffening. Fifteen healthy young men (mean age, 21.7 ± 0.3 years) underwent two experimental trials: rest (RE) and (EX) trials. Following 5-minute MS task, the participants RE trial rested on chair (from 10 to 13 after task cessation), whereas those EX performed BS same duration. The heart-brachial pulse wave...
PURPOSE:To clarify the physiological responses to various movement in aerobic exercise using balance ball. And differences between walking and METHODS:Eight healthy men performed ball (BB). Respiratory metabolism hart rate were measured during BB. Subjects walked 5 speeds (4km/h, 5km/h, 6km/h, 7km/h 8km/h) on treadmill ergometer. During BB, subject was sitting BB bounding with upper lower limb movements. The movements fourteen patterns; only, four movements, five RESULTS:There no intensity...
Single-tooth sandals under new development have special material and shape characteristics. Exercises with single-tooth can increase pressing stimulus on the soles of feet, thereby suppressing a decline in medial longitudinal arch elevating sole surface temperature. This study thus aimed to examine effects exercise Sixteen young adults (23 ± 5 years) participated 20 min stepping spot. They randomly put regular normal sandal (N conditions) or (Z each left right side. Before after exercise,...
