Purpose: A number of nutritional strategies have been developed to optimize nutrient delivery prior to exercise. As a result, various pre-workout supplements have been developed to increase energy availability, promote vasodilation, and/or positively affect exercise capacity. The purpose of this study was to examine the effects of acute pre-workout dietary supplement ingestion with and without synephrine on serum creatine in healthy, active volunteers. Method: We randomized 25 apparently healthy and recreationally active men (n=20) and women (n=5) (21.76±3.00 yr, 15.24±5.26% fat, 25.09±3.03 kg/m2) in a double-blind, crossover, randomized and placebo- controlled manner to acutely ingest (1) a dextrose flavored placebo (PLA); (2) a pre-workout supplement (PWS) containing 3 g beta alanine, 2 g creatine nitrate, 2 g arginine AKG, 300 mg N-acetyl tyrosine, 270 mg caffeine, 15 mg Mucuna pruriens; or, (3) PWS + 20 mg synephrine (PWS+S). Initial venous blood serum collections followed 10-12 hours of fasting, with a second and third collection 30-min and 90-min following a pre-workout supplement ingestion. Participants repeated the experiment after a one-week washout period with the alternate supplements in a randomized and counterbalanced manner. Plasma was subsequently extracted and stored at -80°C, and then analyzed by calorimetric assay kits to measure serum creatine level. Data presented mean ± SD and mean change ± 95% CI. Data were analyzed by two-way repeated measure ANOVA and one-way repeated measure ANOVA. Result: We observed significant effects for treatment (p<0. 001), time (p<0. 001), and the treatment x time interaction (p<0.001) on serum creatine. Overall, significant differences for creatine were observed for PWS+S (2.62 μmol/L; 95% CI, 2.29, 2.94) and PWS (2.31 μmol/L; 95% CI, 1.97, 2.65) vs. PLA (0.71 μmol/L; 95% CI, 0.63, 0.80). The effect also showed significant differences at 30-min (2.37 μmol/L; 95% CI, 2.02, 2.71) and 90-min (2.57 μmol/L; 95% CI, 2.14, 2.99) from pre-ingestion (0.71 μmol/L; 95% CI, 0.63, 0.78). Treatment x time interaction showed significant increases in serum creatine levels for PWS+S (3.28 μmol/L; 95% CI, 2.80, 3.76) and PWS (3.13 μmol/L; 95% CI, 2.52, 3.74) vs. PLA (0.69 μmol/L; 95% CI, 0.60, 0.78) at 30-min, and PWS+S (3.89 μmol/L; 95% CI, 3.21, 4.57) and PWS (3.10 μmol/L; 95% CI, 2.48, 3.71) vs. PLA (0.71 μmol/L; 95% CI, 0.61, 0.82) at 90-min of supplement ingestion. Although there was no significant difference between PWS+S and PWS (p=0.48) at 30-min post-ingestion, at 90-min post-ingestion, serum creatine was significantly increased (p<0.001) in PWS+S subjects (0.79 μmol/L; 95% CI, 0.37, 1.21) compared to PWS subjects. Area under the curve (AUC) analysis also showed a significant difference between treatments (p<0.001). Post-hoc comparisons demonstrated significant differences between PWS+S (5.57 μmol/L; 95% CI, 4.88, 6.25) and PWS (5.50 μmol/L, 95% CI, 4.26, 5.82) vs. PLA (1.42 μmol/L; 95% CI, 1.25, 1.59) for 2-hrs. PWS+S (0.53 μmol/L; 95% CI, 0.02, 1.04) vs. PWS was also showed significance throughout testing. Conclusion: The acute ingestion of a dietary PWS containing beta alanine, creatine nitrate, arginine AKG, N-acetyl tyrosine, caffeine, and Mucuna pruriens increased serum creatine levels 2-hr post-ingestion compared to PLA and the addition of synephrine enhanced this effect.

일회성 유산소운동 후 다량의 알코올섭취가 HPA축과 체온의 주기리듬에 미치는 영향

The aim of this study was to investigate the effects of an acute large amount of alcohol ingestion(17% distilled alcohol, 9ml/㎏ per 1㎏ body weight) after aerobic exercise on circadian rhythm of HPA axis(ACTH, cortisol), body temperature. Alcohol degradation ability also measured. Twelve male (average age 33.5years, weight 73.1㎏) took part in this study and performed 3 trials (alcohol ingestion after exercise, alcohol ingestion. placebo ingestion) in a randomized, cross-over design at intervals of 1 weeks. They drank dry white wine(mixed with orange) at 18:00hours during 45 minutes. Placebo treatment ingested identical amount of fluid not contained alcohol. Resting blood sample extracted at 24:00hours and 0700hours(following day) for measuring circadian variation. Extra blood also extracted during 30, 120min after alcohol ingestion for alcohol degradation ability. Exercise treatment group performed running at 70%HRmax during 30 minutes by treadmill. Blood cortisol concentration were significantly high by only alcohol ingestion as compared to exercise+alcohol ingestion and placebo ingestion treatment during 07:00 and 24:00hours. The present findings suggest that large alcohol ingestion may deteriorate circadian rhythm and exercise before alcohol ingestion alleviate thus alcohol ingestion related circadian rhythm disorder.

FE 群은 4분에 증가했고 F 群보다도 높았다. 擴張期血壓은 N 群이 에타놀 投與後 4 및 10분에 有意하게 높았으며, 心博數는 W 群은 물 投與後 20분에 증가했고, 에타놀 投與後 N 群은 별 변화가 없었으나, F群은 증가하여 20분에 최고치를 나타내고 120분까지도 높았으며 10 및 60분은 W 群보다 높았다. 運動後 WE 群, NE 群 및 FE 群 모두 증가했으며, 이로서 NE 群은 4분에 WE 群보다 낮았고 N 群보다는 높았으며, FE 群은 F 群보다 높았다. 이상을 綜合해 볼때 에타놀이 直腸溫度를 감소시키고 皮膚溫度를 증가시키며, 이런 현상이 얼굴 붉은 群에서 더 크게 나타난 것은 에타놀에 의한 血管擴張과 休息中인 顔面 毛細管의 活性等이 얼굴 붉은 群에서 더 顯著함을 의미하고, 運動으로 體溫이 증가한 것은 運動中 代謝가 旺盛하여 熱生産이 증가된 것을 의미한다. 또한 血壓은 運動負荷後 급증하였고, 心博數는 얼굴 붉은 群에서 에타놀 投與 및 運動後에 안 붉은 群에 비해 크게 높은 값을 보였다. The facial flush associated with ethanol ingestion is believed to be more prominent among the oriental people than the caucasian population, and is attributed to the total lack or a considerable decrease of the liver aldehyde dehydrogenase level. However, a little has been reported on the change of the body temperature, including the facial skin temperature, which may lead to some cluses as to the redistribution of blood to the surface areas of the body. In the present study, an effort was directed to elucidate the possible change of the body temperature including the rectal and some surface areas of the body in men showing facial flush following acute ethanol ingestion. Also physical exercise was combined with ethanol ingestion and the change of the body temperature was compared with the non-flushed subjects either with ethanol ingestion or exercise alone. Fifty-five healthy male college students were randomly selected for the study and after 6 or more hours of fasting, either 3 ml of 25% ethanol(Soju) per liter of total body water(Experimental group) or the same dose of water(control group) was administered. Exercise performed was the vertical jumping on a rebounder for 3 min immediately after drinking. The subjects were classified into 6 groups; i, e, water ingestion(W), flushed(F) and non-flushed(N) groups after ethanol ingestion, water ingestion and exercise(WE), flushed(FE) and non-flushed(N) groups after ethanol ingestion, water ingestion and exercise(WE), flushed(FE) and non-flushed(NE) groups after ethanol ingestion and exercise. The telethermometer 44TA by the Yellow Spring Instrument Co. was used for the measurement of temperature, and the rectal, thigh skin, forehead skin, cheek skin and neck skin temperature was measured. The systolic and diastolic peessure as well as heart rate also were recorded. The rectal temperature both in flushed(F) and non-flushed(N) groups were lowered comparing with the water ingested control, and WE group showed elevated rectal temperature while NE group showed lowered values at 40, 60 and 120 min after the exercise. The FE group showed a higher rectal temperature at 10 min but decreased values were obtained at 45 and 60 min after the exercise. The thigh skin temperature in N group showed little change but F, NE and FE groups all showed elevated values comparing with the control. The forehead skin temperature in N group showed elevated values at 30, 45, 60 and 90 min after ethanol ingestion, and F group increased temperature at 45 min comparing with W group. After the exercise, both WE and NE groups showed lowered values while FE group showed increased value. NE group showed decreased value at 4 min after the exercise comparing with N group while FE group at 10 min showed a higher value than WE group. The cheek skin temperature in F group was generally higher than W group throughout the experiment. After the exercise, WE group showed a higher value at 20 min while NE group showed decreased value at 40, 90 and 120 min whereas FE group showed higher values from 10 min through 120 min. The neck skin temperature both in N and F groups showed elevated values after ethanol ingestion comparing with the control. WE and NE groups showed generally lowered neck skin temperature after the exercise while FE group showed elevated values at 20 and 60 min after the exercise. The systolic and diastolic blood pressure were generally elevated in all the groups, and FE group in particular showed higher values at 4 min which was also higher than F group. From the above, it is concluded that ethanol ingestion results in the decrease of the rectal temperature and increase of the skin temperature. The above-mentioned phenomena are more prominent in the flushed group, which suggests that the dilatation of the peripheral blood vessels and the activation on the dormant facial capillaries are more marked in the flushed subejcts. The general elevation of the body temperature after the exercise may be the result of the enhanced general metabolism leading to the increased production of bodily heat.

Characteristics of Plastic Debris Ingested by Sea Turtles: A Comprehensive Review

문예림,심원준,홍상희 한국해양과학기술원 2023 Ocean science journal Vol.58 No.4

Sea turtles, an ecologically vital marine species, face the mounting threat of plastic ingestion. To devise effective mitigation strategies, a nuanced understanding of the characteristics of ingested plastics is essential. Previous reviews have predominantly concentrated on the frequency of occurrence (%FO) and quantity of ingested plastics. In this study, we present an update to the literature on %FO and quantity of ingested plastics and also introduce a novel review of the morphology, color, and polymer composition of ingested plastics. This analysis draws upon 110 scholarly articles on plastic ingestion by sea turtles. Additionally, we explore geographical variations in both the quantity and characteristics of ingested plastics. Most of the analyzed studies were conducted in the Americas and Europe. We found that approximately 54% of examined sea turtles had ingested plastic debris. Loggerhead sea turtles ingested more foams than green sea turtles (Wilcoxon rank-sum test, p < 0.05). By contrast, green sea turtles exhibited a higher ingestion on films (Wilcoxon rank-sum test, p > 0.05). Our study also underscored the paucity of data regarding the original usage of ingested plastics. White and transparent plastics were most commonly ingested. Additionally, polymers with a lower density than seawater, such as polyethylene, polypropylene, and their copolymers, were frequently found. We strongly advocate for future studies to furnish more comprehensive data regarding the ingested plastics, including quantities, morphological and chemical properties, and origins. Such detailed information is indispensable for shaping well-informed and effective strategies to combat plastic ingestion in marine life.

<P>The sense of taste is an essential chemosensory modality that enables animals to identify appropriate food sources and control feeding behavior. In particular, the recognition of bitter taste prevents animals from feeding on harmful substances. Feeding is a complex behavior comprised of multiple steps, and food quality is continuously assessed. We here examined the role of pharyngeal gustatory organs in ingestion behavior. As a first step, we constructed a gustatory receptor-to-neuron map of the larval pharyngeal sense organs, and examined corresponding gustatory receptor neuron (GRN) projections in the larval brain. Out of 22 candidate bitter compounds, we found 14 bitter compounds that elicit inhibition of ingestion in a dose-dependent manner. We provide evidence that certain pharyngeal GRNs are necessary and sufficient for the ingestion response of larvae to caffeine. Additionally, we show that a specific pair of pharyngeal GRNs, DP1, responds to caffeine by calcium imaging. In this study we show that a specific pair of GRNs in the pharyngeal sense organs coordinates caffeine sensing with regulation of behavioral responses such as ingestion. Our results indicate that in <I>Drosophila</I> larvae, the pharyngeal GRNs have a major role in sensing food palatability to regulate ingestion behavior. The pharyngeal sense organs are prime candidates to influence ingestion due to their position in the pharynx, and they may act as first level sensors of ingested food.</P>

The aim of this study was to investigate the effects of acute large alcohol ingestion(17% distilled alcohol, 8ml/㎏ per 1㎏ body weight) on vascular function(ET-1), cardiovascular function(heart rate, blood pressure) and lactate. Twelve recreationally trained middle aged male took part in this study and performed treadmill running(during 30 minutes) with alcohol ingestion, placebo ingestion and alcohol ingestion after acute exercise(75% hear rate reserve). Each subject performed 3 trials in a randomized, cross-over design at intervals of 1 weeks. All parameters were measured next day morning(12 hours after alcohol consumption). Systolic blood pressure and lactate were significantly high by alcohol ingestion as compared to placebo ingestion. Acute exercise before alcohol ingestion alleviated alcohol induced systolic blood pressure increase. The present findings suggest that large alcohol ingestion may deteriorate cardiovascular function although the blood alcohol concentration was completely removed and acute exercise was beneficial for such alcohol ingestion induced blood pressure increase.

Purpose: To study the relationship between temporary refractive errors and changes in optical components in eyes after alcohol ingestion. Methods: Sixteen men of 23.8±2.2 years ingested the alcohol (0.70 g/kg body weight). Refractive errors, corneal thickness, corneal eccentricity, corneal curvature, pupil size, intraocular pressure, and length of ocular axis were measured at 1 h, 4 h, and 24 h after alcohol ingestion, and all values were compared with those of before ingestion. Results: At 1 h after alcohol ingestion, refractive errors showed more myopic (p<0.001), corneal curvature increased, and both pupil size and intraocular pressure decreased significantly (p<0.05, p<0.01). Length of ocular axis was longer than before alcohol ingestion. Conclusions: Alcohol ingestion can temporarily induce the more myopic errors through changes of corneal curvature and length of ocular axis compared with non-alcoholic condition.
