Exercise, stress and Star Wars: Best of 2017 roundup

Happy New Year! In 2018, we look forward to more physiology fun, and to giving you an insight into the exciting new developments in the Science of Life!

Physio-what, you ask? Take a look at our animation below introducing physiology! Scroll down to find out more about a centuries-old shark patrolling the deep Arctic Ocean, how being active gives children’s hearts a head start for life, and why it’s time scientists took back control from exercise gurus, in our best of 2017 roundup!

1. Exercise scientists should fight the exercise gurus

Exercise gurus build strong rapports with their audience to encourage commitment, but they will often simplify a large body of scientific evidence to back up their advice.

In this post, Gladys Onambele-Pearson and Kostas Tsintzas discuss the risks of letting exercise gurus disseminate exercise science to the public, and why it may be time for scientists to become the actual celebrities.

2. The Myth of a Sport Scientist

There is a mismatch between the perceptions and reality of what a sport scientist is and what skills this career entails: just because exercise scientists use models of sport performance, exercise bouts or physical activity sessions, doesn’t mean that there aren’t complex scientific skills, theories, analytics and techniques behind the work.

3. Shark Diary, Episode I: On the trails of the Greenland shark

How do you keep lab chemicals cool when there’s no fridge in your room? Well, if you’re in chilly Denmark, you could just hang them outside your window.

Holly Shiels did just that in Copenhagen, on her way to Greenland to join a team of physiologists on a shark research mission. Their aim was to gather data on the physiology of the Greenland shark. Clarifying how these animals reach hundreds of years of age without developing diseases associated with human ageing, like cancer and heart disease, could lead to new therapies down the line, and understanding shark physiology is also important for their conservation.

Read more about the mission in this post, and check out watch below to see the researchers braving the icy waters of the North Atlantic and releasing a tagged Greenland shark.

4. Breath of the Sith: a case study on respiratory failure in a galaxy far, far away

Have you always wondered what actually is going on behind the mask? Darth Vader’s acute respiratory failure appears to be the consequence of a number of factors, including direct thermal injury to the airways, chemical damage to the lung parenchyma caused by inhalation of smoke and volcanic dust particles, carbon monoxide poisoning, as well as secondary effects to his severe third degree burns, which seems to cover ~100 % of his total body surface area.

Read on as Ronan Berg and Ronni Plovsing make a tongue-in-cheek diagnosis of the numerous respiratory ailments of everyone’s favourite Sith Lord.

5. Exercise now, thank yourself later

Exercise is good for the heart, but the benefits fade soon after we stop training… or so we thought. Studies so far have focused on adults, but research published last November in The Journal of Physiology reveals that exercise in early life could have lifelong benefits for heart health.

This is because young hearts are able to create new heart muscle cells in response to exercise, an ability that is mostly lost in adulthood. Glenn Wadley, Associate Professor at Deakin University and author of the study, explains the findings in this post, and makes the case for children to get active!

As if that wasn’t enough reason to exercise, being active is one of three tips that can help relieve the stress we feel for instance at the approach of exams. Watch our animation below to find out more about what stress does to our bodies, and start making good on those New Year resolutions!
