@XavierWoorons @BJSM_BMJ Thanks a lot, Xavier!

[Leonardo Lima @leonardocrlima]

Delighted to share our latest editorial in @BJSM_BMJ on the health benefits of descending stair walking. It was an absolute pleasure collaborating with Prof. Chen and Prof. Nosaka on this manuscript.

Incredibly, the placebo effect is (mostly) not real.

It is a result of statistical confusion. Whenever you have a group with extreme values, they tend to exhibit regression to the mean. Eg. on average, sick people tend to become more healthy over time.

Thus if you give one group medicine, and one group placebo, the placebo group will also tend to get better over time, because of regression to the mean.

People have then misinterpreted this to think that it is the placebo pill that actively does this.

If you want to demonstrate a placebo effect, you have to construct a study where there are three groups:
• A. treatment
• B. placebo
• C. no treatment, no placebo

If B and C get different outcomes, that would demonstrate a placebo effect.

When this has been tried, mainly there has been no provable placebo effect. See the paper in the screenshot. (There is some evidence for an effect for pain, but this get's into a slightly different debate.)

The fact that the placebo effect is mainly not real, fortunately frees us from having to come up with convoluted explanations, as to why the placebo effect would work even when we tell the patient that it is a placebo, as in the quoted tweet.

I’ve handled the review of > 1000 papers at @nature. Over time, you notice aspects of presentation on which reviewers tend to comment. In the interests of minimizing hassles during review, I offer the following suggestions (a bit targeted to climate papers).

Muscle mass is important.

But muscle function is arguably more important.

Particularly when it comes to maintaining our physical independence for longer.

This study found older adults who had low muscle function (assessed via sit-to-stand test) alone were at a much greater risk of losing their independence later in life versus those with low muscle mass (but normal muscle function).

The good news: improving muscle function with resistance training is a low-hanging fruit versus building muscle.

A maior prova de que o sistema universitário privado do Brasil, em sua maioria, não se preocupa com qualidade é que mesmo depois de décadas do mais puro descaso e sucateamento, em praticamente todos os cursos, as universidades públicas dominam qualquer ranking.

[Leonardo Lima @leonardocrlima]

@dudelbem @mauricio_sarkis Eu também passo por esse mesmo motivo. Mas também para não ter que ficar esperando 40 celulares tirarem fotos do meu slide antes de passar para o próximo… Ou esperar os bonitos fazerem uma transcrição exata do conteúdo do slide para os cadernos…

PhDs: your dissertation topic is less relevant to finding a role outisde of academia than your *skills*.

Here's a 🧵 on how to translate skills you already have into corpspeak using examples from my own PhD work experience:

Biological sex is a primary determinant of athletic performance because of fundamental sex differences in anatomy and physiology dictated by sex chromosomes and sex hormones.

Um pós-graduando bolsista dedica, ao menos, 6 anos aos estudos para concluir mestrado e doutorado. Durante esse período, ele pesquisa, publica artigos, cumpre prazos, escreve e defende dissertações. Não é justo que não tenha acesso à Previdência! #PrevidenciaNaPós

Now in-print: Our overview of muscle fatigue (acute strength loss) during max eccentric vs concentric resistance exercise.

The quadriceps appear more "protected" against muscle fatigue and damage from max eccentrics than arms muscles. @MatheusdPinto
