    AbstractThe present study aimed to test the hypothesis that changes in the dermal tissue dielectric constant (TDC) and biomechanical properties of the skin would be correlated with the indicators related to dehydration. Ten healthy adult men were enrolled in three trials: no fluid intake (DEH), ad libitum fluid intake (AL-HYD), and programmed fluid intake (P-HYD) after exercise in a randomized crossover design. The participants performed a pedaling exercise at 60% heart rate reserve until 2% body mass loss. At 120 min after exercise, an incremental exercise test was carried out. Aerobic capacity, body composition, TDC, biomechanical properties of the skin (pliability, viscoelasticity, and total recovery), and indicators related to dehydration in the serum and urine were measured before and 120 min after exercise. Higher values of the pliability and viscoelasticity, and lower value of the total recovery on the hand were demonstrated in the P-HYD trial compared to the DEH trial (all P < 0.05). Changes in the TDC were significantly correlated with changes in body mass (P < 0.05), total body water (P < 0.05), serum osmolarity (P < 0.05), and hematocrit (P < 0.01). Changes in the biomechanical properties of the hand were significantly correlated with changes in body mass, hematocrit, and urine specific gravity (all P < 0.05). The present study showed that the changes in skin characteristics correlated with the body water and dehydration-associated indicators in the serum and urine, thus suggesting that skin characteristics may be useful in the assessment of dehydration.

     概要を見る

    Acute exercise can improve vascular stiffness in the conduit artery, but its effect on the retinal arterioles is unknown. The present study investigated the effects of acute dynamic exercise on retinal vascular stiffness. In experiment 1, we measured the cardio-ankle vascular index (CAVI), carotid artery intima-media thickness (carotid IMT), and retinal blood velocity by laser speckle flowgraphy in 28 healthy old and 28 young men (69 ± 3 and 23 ± 3 yr, respectively). Pulse waveform variables, which were used as an index of retinal vascular stiffness, were assessed by retinal blood flow velocity profile analysis. In experiment 2, 18 healthy old and 18 young men (69 ± 3 and 23 ± 3 yr, respectively) underwent assessment of pulse waveform variables after a 30-min bout of moderate cycling exercise at an intensity of 60% heart rate reserve. There was a significant difference in the baseline pulse waveform variables between the old and young groups. Pulse waveform variables in the retinal arteriole did not significantly change after acute dynamic exercise, whereas CAVI significantly decreased. These findings suggest that retinal vascular stiffness does not change by acute exercise. The effect of exercise on vascular stiffness in the retinal arterioles might be different from that in the conduit artery.NEW & NOTEWORTHY Acute dynamic exercise is well known to improve vascular stiffness in the conduit artery while its effect on the retinal arterioles has been unknown. This study showed that an acute dynamic exercise does not change vascular stiffness in the retinal arteriole in healthy humans. Different responses to acute dynamic exercise in vascular stiffness in retinal arterioles and conduit arteries are suggested.

     概要を見る

    BACKGROUND: Cerebral blood flow (CBF) pulsatility is dampened by large and small arterial buffer functions. Resistance training (RT) improved small arterial buffer function regardless of impaired large arterial compliance. This response to small arterial buffer function with RT may be compensatory adaptation to impaired large arterial compliance for protecting end-organs such as the brain from excessive pulsatile stresses. This study aimed to investigate the effects of changes in large arterial compliance and small arterial buffer functions with RT on CBF pulsatility.METHODS: Twenty healthy men were assigned to either the RT group (N.=10) or the control (CON) group (N.=10). Subjects in the RT group exercised three times/week for 8 weeks. Arterial compliance of common carotid artery was measured as an index of large arterial compliance. Dampening factor (DF) in the cerebral artery and pulsatility index (PI) in the middle cerebral artery (MCA) were used to evaluate small arterial buffer function and CBF pulsatility, respectively.RESULTS: In the RT group, arterial compliance significantly decreased (P<0.05) and DF in the cerebral artery signifi-cantly increased (P<0.05) after intervention compared to baseline. However, there was no change in PI in MCA in both groups. A negative correlation was found between Delta arterial compliance and Delta DF in the cerebral artery (r=-0.671, P<0.05).CONCLUSIONS: These results may suggest that the response of small arteries to RT is a compensatory adaptation to impaired large arterial compliance for protecting end organs from excessive pulsatile stresses.

    Sports Medicine - Open   7 ( 1 )  2021年12月  [査読有り]

     概要を見る

    <title>Abstract</title><sec>
    <title>Background</title>
    Compared with age-matched untrained men, resistance-trained men who have undergone long duration training (&gt; 2 years) at a high frequency (&gt; 5 days/week) may be lower cardiovagal baroreflex sensitivity (BRS) because of central arterial stiffening. Therefore, the purpose of this study was to examine the effect of greater central arterial stiffness in resistance-trained men on cardiovagal BRS in a cross-sectional study to compare resistance-trained men with age-matched untrained men.


    </sec><sec>
    <title>Methods</title>
    This cross-sectional study included resistance-trained men (<italic>n</italic> = 20; age: 22 ± 3; body mass index: 26.7 ± 2.2) and age-matched untrained men (control group: <italic>n</italic> = 20; age: 25 ± 2; body mass index: 23.7 ± 2.4). The β-stiffness index and arterial compliance were assessed at the right carotid artery using a combination of a brightness mode ultrasonography system for the carotid artery diameter and applanation tonometry for the carotid blood pressure. And, the cardiovagal BRS was estimated by the slope of the R–R interval and systolic blood pressure during Phase II and IV of Valsalva maneuver (VM). The participants maintained an expiratory mouth pressure of 40 mmHg for 15 s in the supine position.


    </sec><sec>
    <title>Results</title>
    The β-Stiffness index was significantly higher in the resistance-trained group than in the control group (5.9 ± 1.4 vs. 4.4 ± 1.0 a.u., <italic>P</italic> &lt; 0.01). In contrast, the resistance-trained group had significantly lower arterial compliance (0.15 ± 0.05 vs. 0.20 ± 0.04 mm2/mmHg, <italic>P</italic> &lt; 0.01) and cardiovagal BRS during Phase IV of VM (9.0 ± 2.5 vs. 12.9 ± 5.4 ms/mmHg, <italic>P</italic> &lt; 0.01) than the control group and. Moreover, cardiovagal BRS during Phase IV of VM was inversely and positively correlated with the β-stiffness index (<italic>r</italic> = − 0.59, <italic>P</italic> &lt; 0.01) and arterial compliance (<italic>r</italic> = 0.64, <italic>P</italic> &lt; 0.01), respectively.


    </sec><sec>
    <title>Conclusion</title>
    Resistance-trained group had greater central arterial stiffness and lower cardiovagal BRS Phase IV compared with control group. Moreover, the central arterial stiffening was related to cardiovagal BRS Phase IV. These results suggest that greater central arterial stiffness in resistance-trained men may be associated with lower cardiovagal BRS.

     概要を見る

    Strenuous exercise induces organ damage, inflammation and oxidative stress. To prevent exercise-induced organ damage, inflammation and oxidative stress, rehydrating may be an effective strategy. In the present study, we aimed to examine whether beverage intake after exhaustive exercise to recover from dehydration prevents such disorders. Thirteen male volunteers performed incremental cycling exercise until exhaustion. Immediately after exercise, the subjects drank an electrolyte containing water (rehydrate trial: REH) or did not drink any beverage (control trial: CON). Blood samples were collected before (Pre), immediately (Post), 1 h and 2 h after exercise. Urine samples were also collected before (Pre) and 2 h after exercise. We measured biomarkers of organ damage, inflammation and oxidative stress in blood and urine. Biomarkers of muscle, renal and intestinal damage and inflammation increased in the blood and urine after exercise. However, changes in biomarkers of organ damage and inflammation did not differ between trials (p > 0.05). The biomarker of oxidative stress, thiobarbituric acid reactive substances (TBARS), in plasma, showed different changes between trials (p = 0.027). One hour after exercise, plasma TBARS concentration in REH had a higher trend than that in CON (p = 0.052), but there were no significant differences between Pre and the other time points in each trial. These results suggest that beverage intake after exercise does not attenuate exercise-induced organ damage, inflammation or oxidative stress in healthy males. However, rehydration restores exercise-induced oxidative stress more quickly.

     概要を見る

    Previous studies have not investigated the determinants of resting oxidative stress, including physical fitness, as it relates to redox regulation. The present study therefore was aimed at identifying lifestyle and biological factors that determine resting oxidative stress, including objectively measured physical fitness. In 873 middle-aged and elderly men and women, age and anthropometric parameters, lifestyle-related parameters, medication and supplementation status, physical fitness, biochemical parameters, and nutritional intake status, as well as three plasma oxidative stress markers: protein carbonyl (PC), F2-isoprostane (F2-IsoP), and thiobarbituric acid reactive substances (TBARS), were surveyed and measured. The determinants of PC, F2-IsoP, and TBARS in all participants were investigated using stepwise multiple regression analysis. In PC, age (β = -0.11, P = 0.002), leg extension power (β = -0.12, P = 0.008), BMI (β = 0.12, P = 0.004), and HDL-C (β = 0.08, P = 0.040) were included in the regression model (adjusted R 2 = 0.018). In the F2-IsoP, smoking status (β = 0.07, P = 0.060), BMI (β = 0.07, P = 0.054), and HbA1c (β = -0.06, P = 0.089) were included in the regression model (adjusted R 2 = 0.006). In TBARS, glucose (β = 0.18, P < 0.001), CRF (β = 0.16, P < 0.001), age (β = 0.15, P < 0.001), TG (β = 0.11, P = 0.001), antioxidant supplementation (β = 0.10, P = 0.002), and HbA1c (β = -0.13, P = 0.004) were included in the regression model (adjusted R 2 = 0.071). In conclusion, the present study showed that age, anthropometric index, lifestyle-related parameters, medication and supplementation status, objectively measured physical fitness, biochemical parameters, and nutritional intake status explain less than 10% of oxidative stress at rest.

     概要を見る

    Antimicrobial peptides (AMPs) play an important role in innate immunity in human skin. It is known that AMPs mainly function in the stratum corneum. Therefore, AMP concentrations in the stratum corneum need to be precisely measured to clarify functional and physiological importance of AMPs in cutaneous defence. Tape stripping (TS) is a well-established method by which components in the stratum corneum can be collected. However, the usefulness of the TS method for measuring AMP concentration in human skin remains unclear. Therefore, we compared it with another popular method, skin rinsing, which had been established as a method for measuring AMP concentration in human skin. When investigated on healthy medial forearm using RNase 7, which is one of the typical AMPs, as an index, there was a significant positive correlation between RNase 7 concentrations measured by the TS method at adjacent forearm sites, demonstrating the reproducibility of the TS method. Next, a significant positive correlation was detected in RNase 7 concentrations measured using the TS and the skin rinsing method, indicating that the TS method is comparable to the skin rinsing method. Thus, we speculate that the TS method is useful for measuring AMP concentration in human skin.

     概要を見る

    BACKGROUND: Preceding exercise enhances fat metabolism during subsequent endurance exercise. However, it is unknown which type of exercise most enhances fat metabolism during subsequent exercise. The aim of this study was to examine the influence of preceding resistance or endurance exercise on fat metabolism during subsequent endurance exercise and to compare the effect with that without a preceding exercise.METHODS: Nine male subjects performed the following trials: 1) endurance exercise (E trial), 2) endurance exercise preceded by resistance exercise (R+E trial), and 3) endurance exercise preceded by endurance exercise (E+E trial). There was a 20-min break after the preceding exercise. Subsequent endurance exercise was performed on a cycle ergometer at 80% of the individual ventilatory threshold. Blood and exhaled gas were analyzed respectively.RESULTS: The R+E and E+E trials showed a significantly lower respiratory exchange ratio (RER) and a higher amount of fat oxidation during endurance exercise than those in the E trial (P<0.05). Furthermore, the E+E trial showed a significantly lower RER (0.86 +/- 0.03 vs. 0.84 +/- 0.02) and a significantly higher amount of fat oxidation (0.38 +/- 0.05 g/min vs. 0.44 +/- 0.08 g/min) than those in the R+E trial.CONCLUSIONS: This study suggested that fat oxidation during subsequent endurance exercise was enhanced when a preceding exercise was performed and that endurance exercise as a preceding exercise enhanced fat oxidation more than resistance exercise did.

     概要を見る

    BACKGROUND: Increased arterial stiffness decreases cerebral blood flow (CBF), which plays a vital role in the maintenance of life and cognitive function. Previous studies have shown that high-intensity resistance exercise (HRE) increases arterial stiffness. HRE may decrease cerebral blood flow. However, the effect of increased arterial stiffness associated with HRE on CBF is not fully elucidated. Therefore, this study aimed to investigate the effect of increased arterial stiffness with HRE on CBF.METHODS: Study participants included 8 healthy young men. All subjects performed three exercise trials in a crossover design: HRE, low-intensity resistance exercise (LRE), and aerobic exercise (AE). beta-stiffness index was measured as an index of arterial stiffness, and global cerebral blood flow was measured as an index of cerebral blood flow. These were measured at rest, immediately after exercise, and 10 minutes post-exercise.RESULTS: Global cerebral blood flow was significantly increased immediately after and 10 minutes after AE. In contrast, a significant decrease of global cerebral blood flow was observed immediately after and 10 minutes following HRE. However, no changes were observed in LRE. With HRE, beta-stiffness index was significantly increased immediately after and 10 minutes post-exercise. In contrast, no differences were observed in arterial stiffness associated with aerobic exercise and LRE. A negative correlation was found between global cerebral blood flow and arterial stiffness at rest and immediately after and 10 minutes post-exercise.CONCLUSIONS: These results suggested that HRE increased arterial stiffness and decreased cerebral blood flow.

     概要を見る

    PURPOSE: It remains unclear whether rehydration restores retinal blood flow reduced by exhaustive exercise. We investigated the effect of fluid intake on retinal blood flow after exhaustive exercise. METHODS: Blood flow in the inferior (ITRA) and superior temporal retinal arterioles (STRA) was measured before and after incremental cycling exercise until exhaustion in 13 healthy males. After the exercise, the subjects rested without drinking (control condition: CON) or with drinking an electrolyte containing water (rehydrate condition: REH) and were followed up for a period of 120 min. To assess the hydration state, the body mass was measured, and venous blood samples were collected and plasma volume (PV) was calculated. RESULTS: Body mass decreased in CON after the trial [- 1.1 ± 0.1% (mean ± SE), p < 0.05]. PV was lower in CON than in REH during recovery. The ITRA and STRA blood flows decreased immediately after exercise from the resting baseline (ITRA; - 23 ± 4% in REH and - 30 ± 4% in CON, p < 0.05). The ITRA blood flow recovered baseline level at 15 min of recovery in REH (- 9 ± 3%, p = 0.5), but it remained reduced in CON (-14 ± 3%, p < 0.05). The STRA blood flow was higher in REH than in CON at 15 min (2 ± 3 vs. - 5 ± 3%, p < 0.05). CONCLUSIONS: The results of this study suggest that the reduction in retinal blood flow induced by exhaustive exercise can be recovered early by rehydration.

     概要を見る

    動脈圧受容器反射は短期的な血圧変動に対して血圧の恒常性を維持する最も重要な調節機構である。この反射の感受性は加齢や高血圧によって鈍化することが報告されている。また、動脈圧受容器反射感受性の鈍化が重篤な不整脈のリスク増大につながることや急性心臓死の前兆となることが報告されている。動脈圧受容器反射は大動脈洞および頸動脈洞が動脈の伸展を感知し、その程度に応じて血圧を調節しているため、大動脈や頸動脈といった動脈の硬化度が動脈圧受容器反射の感受性の低下と関連することが報告されている。
    筋力トレーニングは日常生活動作(ADL)の改善ひいては健康寿命の延伸に寄与することが期待されており、広く推奨されている。一方、筋力トレーニングは動脈硬化を促進させることが報告されている。また、いくつかの研究では、習慣的に筋力トレーニングを実施している者(鍛錬者)は同年代の非鍛錬者よりも動脈硬化度が高いことが示されている。さらに、メタ解析においても同様の結果が得られている。しかし、この動脈硬化がどのような弊害を有しているかについてほとんど検討されていないのが現状である。
    先行研究では、習慣的な運動による動脈の硬化度の変化が動脈圧受容器反射の感受性を変化させることが示唆されている。以上のことから、筋力トレーニングに伴う中心動脈スティフネスの増加およびコンプライアンスの低下は動脈圧受容器反射の感受性を鈍化させる可能性があると思われる。そこで、本研究課題は筋力トレーニングに伴う動脈硬化が動脈圧受容器反射の感受性に及ぼす影響を検討することとした。
