Tiny robots are making big waves in medicine. These little helpers, called microrobots, can move around without wires. They could one day help doctors treat patients without surgery. But there's a problem. Most microrobots are made from soft materials. They can't move well in fast-flowing blood. They also don't respond well to magnetic fields. This makes them hard to...
First, let us talk about what happens to blood flow in parts of the body that are not moving during exercise. Most people assume that as exercise gets harder, blood flow to these inactive areas drops. This is because the body is thought to prioritize blood flow to working muscles. However, this idea might not be entirely accurate. In a recent study, researchers put ...
Ketone monoester (KME) supplements can quickly boost beta-hydroxybutyrate (β-OHB) levels in the blood. This might change how blood flows in the brain. But how exactly does this happen? And does the amount of KME matter? A recent study tried to figure this out. The study involved 20 young adults, half of whom were female. They were given either a high dose of KME, a ...
Moyamoya disease is a tricky condition that affects blood flow in the brain. It can cause problems with how kids process information, especially when it comes to remembering things in a specific order. This isn't just any old memory issue. It's a unique challenge that kids with moyamoya disease often face. It's like trying to keep a list of things in your head, but t...
The heart is often seen as a perfect matchmaker, adjusting its output to meet the body's needs during exercise and heat stress. However, recent findings suggest that this might not always be the case. The heart's response to these demands involves two key factors: stroke volume, or the amount of blood pumped with each beat, and heart rate, or the number of beats per ...
Blood flow restriction (BFR) training has been a hot topic in the fitness world. It's a method where blood flow to muscles is restricted during exercise. This can be done using special bands or wraps. The idea is to make muscles work harder with less weight. But does it really help athletes? Let's break it down. Researchers dove into this question. They looked a...
Basketball is a game that demands peak performance. But what happens when players need to reduce their training load? A recent study looked into something called Blood Flow Restriction (BFR) training during a period called the "taper phase. " This phase is all about cutting back on how much exercise players do, while still keeping the intensity high. The study broug...
Have you ever wondered how different types of training can impact athletes with low back pain? A recent study explored this by comparing two methods: low-load blood flow restriction training (LL-BFRT) and heavy-load resistance training (HL-RT). The focus was on male collegiate athletes dealing with chronic non-specific low back pain (CNLBP). This condition is common ...
Did you know that betamethasone, a medication commonly used to speed up lung and heart development in preterm babies, could actually change how blood flows in their bodies during and after birth? Scientists studied this in baby lambs, which are often used to understand human infants better. They found that betamethasone increases blood flow to the lungs but reduces i...
You've probably heard that grapes and blueberries are great for your heart. That's thanks to flavanols, powerful compounds packed inside these tiny fruits. Researchers have found that these fruits can reduce the risk of heart disease, but they aren't quite sure how they work. One reason is that flavanols aren't easy for our bodies to absorb. Scientists have been stu...
