As I write this put up, the third spherical of the US Open Golf event is going down as is Euro2020 (a yr after being suspended), and Father’s Day is about to be celebrated in america. Meaning summer time is ‘full on’ within the Northern Hemisphere.
Which additionally means loads of of us are taking trip and it has develop into arduous to trace down some authors to affix me for a podcast!!!

Mixing metaphors: the outdated adage has it that you just make lemonade out of lemons, and since lemonade is an unofficial drink of summer time, you all get a particular summer time deal with with this, the forty ninth podcast for the journal.
I’m utilizing this second to check out a particular podcast format I’ve been toying with in my head. I’m hanging out getting visitors for this podcast, and so I’ll serve you up ‘me’ as a visitor!
Let me know when you suppose I’m lemonade….or a lemon!
I’ve been an admirer of the American Journal of Sports activities Medication’s ‘5 in 5’ podcast for a number of years. The hosts zip via 5 of the manuscripts in a latest version of AJSM in roughly 5 minutes. It’s an excellent technique to get some snack chunk dimension data and I encourage the readers of CJSM and the listeners of our podcast to take a look at AJSM’s podcast.
With a tip of a hat to our eminent colleagues at AJSM, I’ve determined to name at present’s podcast “2 in 10”: I’ll stroll listeners via two of the research printed in the Might 2021 CJSM. The theme for at present’s podcast is the really international nature of CJSM, with the 2 research profiled coming from creator groups in Israel and Ghana/Germany.
Within the spirit of experimentation, I’m together with the transcript of this podcast on the backside of this put up.
As ever you try all of our podcast choices at iTunes (the place you too can subscribe to and touch upon the podcasts) and on the principle journal’s webpage.
And at last, as we not far away towards our fiftieth podcast, I’m greater than ever keen to listen to from listeners suggestions about how we will enhance. Is that this new format an gratifying one? Please ensure once more to touch upon iTunes or within the remark part right here on the weblog put up.
Cheers to your summer time!

Welcome to at present’s CJSM podcast – the 49th on this journal’s historical past.
With #50 a month or so away, I needed to attempt one thing new this time – I’ve no visitor to interview at present. There’s simply yours really.
I don’t plan on having this as a recurring factor, however I’m open to suggestions. For a very long time I’ve admired the method taken by a sister journal on the planet of sports activities drugs: AJSM’s “5 in 5” podcast.
AJSM provides a mixture of podcasts, together with some in-depth analyses on their at all times glorious analysis choices. However on a month-to-month foundation, AJSM does a “5 in 5” podcast, the place in 5 minutes they run down 5 articles in that month’s publication.
I find it irresistible. And I encourage you to take a pay attention. At present I’ll try to do one thing of the identical for the CJSM Might 2021 difficulty. And I tip the hat to AJSM for the inspiration. However I gained’t be ‘doing’ 5 articles – solely two.
I’d like to start out this experiment then with two articles which come from ‘abroad,’ as outlined by outdoors North America, with an acknowledgement of my provincialism. As an vital sidebar, I wish to be aware that it’s arduous to outline geography when one is speaking a couple of journal like CJSM and a writer like Wolters Kluwer. Wolters Kluwer is definitely trans-Atlantic: headquartered within the Netherlands and in Philadelphia, in america. And as for CJSM, we had been based by the Canadian Academy of Sport and Train Medication and are the official journal of each CASEM and the American Medical Society for Sports activities Medication (AMSSM), with additional relationships with affiliated societies in Australiasia (ACSEP) and America (AOASM). Difficult geography, don’t you suppose?
However at present, I needed to deal with some work from the broad international neighborhood of sports activities drugs analysis that informs CJSM. In 2020, we acquired manuscripts from 54 nations, and although we didn’t settle for all submissions, contributions from Japan to S. Africa, from Brazil to Sweden, from China to Qatar made it via the varied editorial ranges to realize acceptance. Really, there’s excellent work being executed in sports activities drugs analysis throughout the globe, and I encourage all potential authors listening to contemplate CJSM if you find yourself deciding to submit your work. We’re a worldwide platform.
The primary research I’d like to focus on is a nifty piece of authentic analysis from Israel: “The Cardiovascular Reserve Index: A Noninvasive Medical Perception Into Warmth Intolerance.” Israel has over time contributed significantly to our understanding of exertional warmth sickness. On this research the authors in contrast 16 male warmth illiberal people to 79 warmth tolerant people utilizing a regular heat-tolerance check (HTT) as their intervention. They assessed and in contrast two indices — the dynamic coronary heart fee reserve (dHRR) index and the cardiovascular reserve index (CVRI) – by taking a look at their capability to foretell train related warmth intolerance.
The warmth tolerance check used is described as strolling for a period of 120 minutes at a fee of 5 km/hour and a gradient of two% in a local weather managed atmosphere of 40 levels Celsius and 40% humidity. Research members walked with a rectal thermistor in place. HR and BP had been measured repeatedly together with rectal temp. On the conclusion of the check, these people with a rectal temperature >38.5 levels or a coronary heart fee > 150 had been outlined as having warmth intolerance.
The equations for the dHRR and the CVRI are considerably complicated and listeners can go to this podcast’s accompanying weblog put up at cjsmblog.com for a hyperlink to the research to see the equations first hand.
When wanting on the two indices’ capability to discriminate between people discovered on this check to be HI or HT, the authors regarded on the receiver working attribute curve and located the CVRI (with an space underneath the curve of 93.2%) to be considerably superior to the dHRR (with a worth of 76.8).
I’ll conclude with a borrowing from the authors’personal conclusions: “The outcomes counsel that the CVRIA, assessed from noninvasive measurements, can be utilized as a surrogate index for figuring out intolerance to warmth. Greater than being a predictor, the CVRI gives a brand new scientific perception into this situation as a result of it characterizes the effectivity of a person’s thermoregulatory mechanism and hints that an impaired Cardiovascular reserve could result in warmth intolerance.”
The following research within the Might 2021 CJSM I’d prefer to convey to your consideration comes collectively from Ghana and Germany: “Electrocardiographic and Echocardiographic Findings in Black Athletes: A Normal Overview.”
We regularly publish critiques – together with systematic critiques and meta-analyses – along with our common choices of particular person analysis research. On this Normal Overview the authors used a scientific methodology looking PubMed, Medline and Google Scholar databases via 2017 taking a look at research investigating black African/Afro-Caribbean athletes. Discovering 130 research initially, they winnowed their overview all the way down to 16 research which met pre-selected inclusion/exclusion standards, together with:
- Authentic articles written within the English language
- Contributors had been at present competing at ranges starting from newbie to elite ranges
- Contributors had been of black African descent
- Contributors had been aged 14 to 35 years
- Contributors had been wholesome athletes with none recognized cardiac illness
Research involving athletes youthful than 14 years and older than 35 years and people involving leisure (non-competitive) athletes had been excluded from the overview.
As is well-known, numerous ECG and ECHO research have revealed cardiac morphological diversifications in black athletes that sometimes overlap with phenotypic expression of HCM. This normal overview confirms that with the findings
- On ECG {that a} excessive proportion (10% to 30%) of black athletes have irregular ECGs based mostly on customary studying protocols
- On echo, one other comparatively excessive proportion (10% to 12%) had borderline irregular left ventricular wall thickness of 13 to fifteen mm.
The authors be aware that as an growing # of sporting our bodies (together with the IOC and FIFA) suggest screening ECG and echo in an try to lower the incidence of sudden cardiac arrest or dying throughout sport that particular consideration must be paid to black athletes so as to keep away from pointless exclusion from sport.
I wish to draw the listener’s consideration to an open entry instructional initiative sponsored by the College of Washington and one in all our companion societies, ACSEP, the place one can study extra about ECG interpretation, with particular consideration to the athletes’ coronary heart. The hyperlink to the “e-academy”—uwsportscariology.org/e-academy/ will likely be discovered on this podcast’s liner notes within the weblog
As I wrap up, I wish to remind listeners on our iTunes platform to please fee us and touch upon this system. The suggestions may be very useful to us. I hope you’ve loved this experiment at present with ‘me’ as visitor. However fear not: I’ve some particular visitors lined up for some upcoming podcasts.
As we attain one thing of a milestone with our 50th podcast, I wish to thanks for becoming a member of us on our journey. Bear in mind to go to cjsportmed.com to take a look at the latest within the journal, cjsmblog.com to take a look at our weblog posts, and @cjsmonline to observe us on twitter.
