Improving VO2max through blood protein analysis

My wife and I have recently bought new smartwatches (me: Garmin Venu 2, her: Fitbit Versa 3) and the things they tell us really makes a difference to how we exercise. What’s reported here looks like next level even to the detailed stats we’ve got already.

The team identified a set of 147 proteins that could indicate a person’s VO2max, a marker of cardiorespiratory fitness, before the exercise program, and then a set of 102 proteins that could indicate the change in VO2max after it had been completed. Some of these proteins were also found to be linked to a higher risk of early death, highlighting a connection between cardiorespiratory fitness and long-term health.

“We identified proteins that emanate from bone, muscle, and blood vessels that are strongly related to cardiorespiratory fitness and had never been previously associated with exercise training responses,” says Gerszten.

Based in these revelations, the scientists developed what they call a protein score, which could be used to predict how much a person’s VO2max would change as a result of the exercise. Baseline levels of certain proteins were able to predict who would respond to the exercise with more reliability than established patient factors, according to the scientists, and also predicted which subjects would be unable to significantly improve their VO2max even after a sharp uptake in physical activity.

The World’s Oldest Story? Astronomers Say Global Myths About ‘Seven Sisters’ Stars May Reach Back 100,000 Years — “Why are the Australian Aboriginal stories so similar to the Greek ones? Anthropologists used to think Europeans might have brought the Greek story to Australia, where it was adapted by Aboriginal people for their own purposes. But the Aboriginal stories seem to be much, much older than European contact. And there was little contact between most Australian Aboriginal cultures and the rest of the world for at least 50,000 years. So why do they share the same stories?”

🚶‍♂️ The joy of steps: 20 ways to give purpose to your daily walk — “We need to gallivant around outside in daylight so that our circadian rhythms can regulate sleep and alertness. (Yes, even when the sky is resolutely leaden, it is still technically daylight.) Walking warms you up, too; when you get back indoors, it will feel positively tropical.”

🔐 How Law Enforcement Gets Around Your Smartphone’s Encryption — “Cryptographers at Johns Hopkins University used publicly available documentation from Apple and Google as well as their own analysis to assess the robustness of Android and iOS encryption. They also studied more than a decade’s worth of reports about which of these mobile security features law enforcement and criminals have previously bypassed, or can currently, using special hacking tools.”

🚫 Misinformation dropped dramatically the week after Twitter banned Trump and some allies — “The findings, from Jan. 9 through Friday, highlight how falsehoods flow across social media sites — reinforcing and amplifying each other — and offer an early indication of how concerted actions against misinformation can make a difference.”

😲 The Ethics of Emotion in AI Systems (Research Summary) — “There will always be a gap between the emotions modelled and the experience of EAI systems. Addressing this gap also implies recognizing the implicit norms and values integrated into these systems in ways that cannot always be foreseen by the original designers. With EAI, it is not just a matter of deciding between the right emotional models and proxy variables, but what the responses collected signify in terms of human beings’ inner feelings, judgments, and future actions.”

📚 Bookshelf designs as unique as you are: Part 2 — “Stuffing all your favorite novels into a single space without damaging any of them, and making sure the whole affair looks presentable as well? Now, that’s a tough task. So, we’ve rounded up some super cool, functional and not to mention aesthetically pleasing bookshelf designs for you to store your paperback companions in!”

📱 How to overcome Phone Addiction [Solutions + Research] — “Phone addiction goes hand in hand with anxiety and that anxiety often lowers the motivation to engage with people in real life. This is a huge problem because re-connecting with people in the offline world is a solution that improves the quality of life. The unnecessary drop in motivation because of addiction makes it that much harder to maintain social health.”

⚙️ From Tech Critique to Ways of Living — “This technological enframing of human life, says Heidegger, first “endanger[s] man in his relationship to himself and to everything that is” and then, beyond that, “banishes” us from our home. And that is a great, great peril.”

🎨 Finding time for creativity will give you respite from worries — “According to one study examining the links between art and health, a cost-benefit analysis showed a 37% drop in GP consultation rates and a 27% reduction in hospital admissions when patients were involved in creative pursuits. Other studies have found similar results. For example, when people were asked to write about a trauma for 15 minutes a day, it resulted in fewer subsequent visits to the doctor, compared to a control group.”

🧑‍🤝‍🧑 For psychologists, the pandemic has shown people’s capacity for cooperation — “In short, what we have seen is a psychology of collective resilience supplanting a psychology of individual frailty. Such a shift has profound implications for the relationship between the citizen and the state. For the role of the state becomes less a matter of substituting for the deficiencies of the individual and more to do with scaffolding and supporting communal self-organisation.”
