Elite runners spend more time in air, less on ground, than highly trained but nonelite peers

(University of Michigan) A recent study led by Geoff Burns, an elite runner and postdoctoral researcher at the University of Michigan Exercise&Sport Science Initiative, compared the " bouncing behavior " --the underlying spring-like physics of running--in elite-level male runners (sub-four-minute milers) vs. highly trained but not elite runners.

just thought id repost my reddit qs here for more help: I’m not sure if this is the best sub Reddit for this post or where I should instead put this, but I’ve never felt more burnt out- I’m not even sure if it’s burn out or something else at this pt.

1 Samuel 7 is just another version of the Groundhog Day story that constitutes most of the previous Book of Judges. A leader emerges who rallies the people to return to exclusive veneration of Yahweh, and he rewards them with victory in battle. As I need say no more about that, let me say something about the document we are reading.I have from time to time mentioned the Septuagint and the Masoretic text. The Septuagint is a translation of the Hebrew Bible into Koine Greek, that is the Lingua Franca of the Mediterranean world from the 4th Century BC and many centuries thereafter. The Masoretic text is the authoritative Hebr...

Little is known about the utility of transcatheter aortic valve implantation (TAVI) in patients with cirrhosis of the liver, and their outcomes have not been studied extensively in literature. We performed a retrospective analysis of patients with severe symptomatic aortic stenosis (AS) who underwent transfemoral TAVI with a SAPIEN 3 valve at our institution between April 2015 and December 2018. We identified 32 consecutive patients with evidence of cirrhosis of the liver on imaging (including ultrasound and/or computed tomography) and patients with severe symptomatic AS who underwent transfemoral TAVI with a SAPIEN 3 valve.

This study aimed to investigate the possibility of deodorization of sheep placenta via yeast fermentation. A yeast strain was successfully isolated and identified as a novel Brettanomyces strain (Brettanomyces deamine kh3). The deodorizing efficacy of fermentation of the sheep placenta with B. deamine kh3 was evaluated by 42 panels, based on evaluation of preference, ranking, and aroma profiles, and compared with normal placenta and placenta fermented with B. bruxellensis. The results of the sensory evaluation indicated that fermentation of the sheep placenta with B. deamine kh3 may improve its palatability by increasing f...

Online ahead of print.ABSTRACTCorneal alkali burn, as one of the most serious ophthalmic emergencies, is difficult to be cured by conservative treatments. It is well known that oxidative stress, inflammation, and neovascularization are the main causes of corneal damage after alkali burn, but its underlying mechanism remains to be elucidated. Here, we reported that the expression and phosphorylation (Ser616) of mitochondrial fission protein Drp1 were up-regulated at day 3 after alkali burn, while mitochondrial fusion protein Mf...

Wonwoo Byun The Apple Watch is one of the most popular wearable devices designed to monitor physical activity (PA). However, it is currently unknown whether the Apple Watch accurately estimates children’s free-living PA. Therefore, this study assessed the concurrent validity of the Apple Watch 3 in estimating moderate-to-vigorous physical activity (MVPA) time and active energy expenditure (AEE) for school-aged children under a simulated and a free-living condition. Twenty elementary school students (Girls: 45%, age: 9.7 ± 2.0 years) wore an Apple Watch 3 device on their wrist and performed prescribed free-...

You can say one thing for Professor Mark Haub: He knows how to make a lesson stick. Haub, who teaches nutrition at Kansas State University, wanted to prove to his students that weight loss is simply about calories. So, for 10 weeks, the professor proceeded to eat an 1,800-calorie diet consisting of a Twinkie every three hours. He also dined on Doritos, Little Debbies, sugary cereal and other junk food. When he started, Haub tipped the scales at 201 pounds, which for his height was considered overweight. By the end of his snack-food spree, he had lost 27 pounds, putting him at a svelte 174. The story went viral, with the me...
