Just a reminder that SMART goals are not as empirically sound as you might think they are (at least for physical activity and exercise). Full article: The (over)use of SMART goals for physical activity promotion: A narrative review and critique www.tandfonline.com/doi/full/10....

The (over)use of SMART goals for physical activity promotion: A narrative review and critique
The SMART acronym (e.g., Specific, Measurable, Achievable, Realistic, Timebound) is a highly prominent strategy for setting physical activity goals. While it is intuitive, and its practical value h...

The field of "ultra-processed" food research & its media coverage are littered with poor definitions & comparisons, w misleading conclusions. This creates an illusion that UPFs provide new insights, but it's all slight-of-hand. @mbolotnikova.bsky.social takes a deep dive www.vox.com/future-perfe...

You’re being lied to about “ultra-processed” foods
Coverage of the latest nutrition buzzword is overly broad, arbitrary, and misleading. The problem goes deeper.

Estradiol deficiency as a consequence of aging contributes to the depletion of the satellite cell pool in female mice - PubMed
The effects of aging on the satellite cell pool have primarily been studied in male mice, where the role of cell-intrinsic versus environmental changes on satellite cell function remains contentious. ...

Myth 1: Re-iterating this point over and over again improves psychologists' understanding of statistics in a practically relevant manner.
From Stanley & Spence (2024): https://journals.sagepub.com/doi/full/10.1177/25152459241285885. 
"Myth 1: There is a 95% chance your true score is in your interval
Some authors correctly understand that the Standard Error of Measurement can be used to construct a confidence interval for a specific individual’s true score. This type of interval is an SEM-Single-Test-Taker Interval. Unfortunately, however, sometimes these authors then go on to misinterpret the information provided by the confidence interval. For example, Kaplan and Saccuzzo (2013)"

Bas van Hooren et al recently published a comprehensive review of metabolic equipment With rigorous calibration & operation, and taking out all possible biological variation with *simulated* gas exchange, the error between carts is still ±10+% onlinelibrary.wiley.com/doi/10.1111/...
A figure from https://onlinelibrary.wiley.com/doi/10.1111/sms.14490 showing percentage error for simulated VO2 and VCO2 in 15 different metabolic carts across ranges of 1000-4000 mL/min. The error between carts ranges from -25 to +25%, with most devices clustered around ±10%
"FIGURE 4 Relative percentage error for V̇O 2 (top) and V̇CO 2 (bottom), as a function of the simulated V̇O 2 and V̇CO 2 for each device. Errors are averaged over each step of the “Std” (i.e., RER = 1.00) and “CPX” (i.e., RER increases with increased V̇O 2 ) protocols. Because the simulated V̇CO 2 differed between the “Std” and “CPX” protocols, the average simulated value is depicted on the x-axis in the figure. MC, mixing chamber; RER, respiratory exchange ratio; V̇CO 2 , rate of carbon dioxide production; V̇O 2 , rate of oxygen uptake."

Clinical Researchers: I am here to warn you about a meteor hurling towards us. That meteor represents increasing scrutiny of clinical research; and in particular how we approach data collection, analysis, interpretation and reporting. Prepare now, or face the consequences. 1/

So look. I've given about 20 talks where I highlight clinical research waste, and I now always ask the audience if they recognize that figure below. The answer is *always* the same - overwhelmingly No. If *you* recognize it, because you are here and informed, you must help spread the word. Please.

Left, a non-randomized study showing that saunas significantly decrease arterial stiffness. Right, a randomized, crossover study, showing no benefits on arterial stiffness/blood flow. Note the colossal difference in media attention. In the media, sensational studies > robust ones. #science #media
