「Magnesium And Space Flight」を編集中

<br>Magnesium is an essential nutrient for muscle, cardiovascular, and bone health on Earth, and during space flight. We sought to evaluate magnesium status in 43 astronauts (34 male, 9 female; 47 ± 5 years old, mean ± SD) before, during, and  [https://2z7anisvathqw4bpgkc5jno5vzrettjbcnyo2qlbaeqjye7corsa.cdn.ampproject.org/c/s/fsianp04.nayaa.co.kr%2Fbbs%2Fboard.php%3Fbo_table%3Dsub05_03%26wr_id%3D154582 [Redirect-Meta-0]] after 4-6-month space missions. 27 (17 male, 10 female), 35 ± 7 years old). We evaluated serum concentration and 24-h urinary excretion of magnesium, along with estimates of tissue magnesium status from sublingual cells. Serum magnesium increased late in flight, while urinary magnesium excretion was higher over the course of 180-day space missions. Urinary magnesium increased during flight but decreased significantly at landing. Neither serum nor urinary magnesium changed during bed rest. For flight and bed rest, significant correlations existed between the area under the curve of serum and urinary magnesium and the change in total body bone mineral content. Tissue magnesium concentration was unchanged after flight and bed rest. Increased excretion of magnesium is likely partially from bone and partially from diet, but importantly, it does not come at the expense of muscle tissue stores. While further study is needed to better understand the implications of these findings for longer space exploration missions, magnesium homeostasis and tissue status seem well maintained during 4-6-month space missions.<br><br><br><br>Why Did I Gain Weight After Working Out? There are several research-backed reasons why you might notice a slight weight gain after exercise. These include muscle gain, water retention, post-workout inflammation, supplement use, or even undigested food. In most cases, post-workout weight gain is temporary. Here is what you need to know about gaining weight after working out. Why Did I Gain Weight After Working Out? Gaining weight after working out is likely due to muscle fiber inflammation, muscle glycogen and water weight gain, and over time, muscle mass gain. If weight loss is your goal,  [https://bbarlock.com/index.php/His_Career_Was_On_The_Move Visit site] seeing an increase on the scale when you've been making an effort to exercise can be frustrating. However, it is often a normal, common occurrence that is likely temporary. Here are some of the reasons why it might be happening to you. You will likely gain muscle when you start working out. How much muscle you gain depends on your diet and the type of workouts you do.<br><br><br><br>But any increase in physical activity is likely to produce at least some improvements in strength and muscle mass. If you participate in strength training workouts and consume adequate protein, you're likely to see more significant increases in muscle mass. Genetics also play a role in the amount of muscle mass you gain when starting an exercise program. If you tend to gain muscle easily, consider yourself lucky. Muscles help to shape a strong, healthy body. Some people put on muscle more quickly than others. But when you gain muscle, the number on the scale is likely to increase. In fact, even if you're also losing fat, you may see an increase on the scale. Muscle is more dense than fat, but it takes up less space. That means if you gain muscle, your scale weight may go up even as you're losing body fat. If you've been working out regularly, it's possible for you to lose inches even if you're not losing weight.<br><br><br><br>A higher number on the scale could mean that you are losing fat while gaining muscle-a positive trend that leads to a leaner, stronger body. Water retention is a common cause of temporary weight gain. Pre-menopausal people are especially prone to body-weight fluctuations throughout the month due to hormonal changes. If you have periods, you may notice some degree of bloating immediately before and during your period. Exercise can help reduce pre-menstrual symptoms, so it's helpful to keep up with your workouts, though you may still see an increase on the scale. Studies have shown that fluid retention peaks on the first day of menstrual flow. It is lowest during the mid-follicular period (the middle phase of your cycle) and gradually increases over the 11 days surrounding ovulation. The degree to which you see an increase on the scale varies from person to person, but at least a slight increase in weight-even after exercise-is normal.<br><br><br><br>Another common reason for water weight gain is increased sodium intake. Consuming high-salt foods can cause an increase in body weight. Studies have shown that after eating salty foods, most people increase water intake, but do not necessarily produce more urine. The extra fluid in the body adds up to pounds on the scale. Some people are very sodium-sensitive and may retain more water. Keep in mind that even if you aren't adding salt to your food, it may still be lurking in the processed foods and beverages that you consume. Even some healthy, nutrient-rich foods like soup, cottage cheese, and canned beans may contain excess sodium. Your workout itself may be causing weight gain-at least temporarily. But this increase may indicate that you are exercising hard enough to see actual results. Very simply put, exercise (especially weight training) damages muscle tissue. The repair process after exercise allows muscles to grow and get stronger. But in the meantime, inflammation occurs in the tissues.<br>
