Podcast MIC Movimento Informado pela Ciência -- Comportamento sedentário e saúde

2025-06-29

Welcome to the second MIC podcast.

This time, we talked with PhDs Pedro Júdice and Sabrina Teno about sedentary behavior and health.

Take a deep dive with us in this long-duration podcast where the promotion of movement is informed by science.

As usual, the hosts are Maria Fernanda Souza and António Palmeira.

Cristo Luís did the production, recording, and editing.

Tema 1: Conceitos e história do estudo do CS – Prof. Pedro.

Breve descrição

A investigação sobre comportamento sedentário tem evoluído significativamente ao longo das últimas décadas, embora ainda haja alguma confusão sobre o seu significado e sobre por que ele precisa ser estudado no contexto da atividade física.

Sugestão de perguntas

  1. Qual o conceito de comportamento sedentário e por que ele é confundido com inatividade física?
  2. Desde quando se estuda os malefícios do CS?
  3. Quais as principais mudanças que aconteceram com o tempo na pesquisa do CS? (Espera-se que aqui o Prof. Pedro fale sobre as formas de monitoramento do CS, além de outras coisas).

Tema 2: Enquadramento do CS nas 24 horas de movimento – Sabrina

Breve descrição

Diversos países desenvolveram diretrizes próprias para atividade física e comportamento sedentário, com base em evidências científicas e nas recomendações globais da Organização Mundial da Saúde (OMS). No entanto, as Diretrizes Canadenses de Movimento nas 24 Horas (Canadian 24-Hour Movement Guidelines - An Integration of Physical Activity, Sedentary Behaviour, and Sleep), não se concentraram em apenas em um único comportamento de movimento (AF), mas sim em como todos eles se integram.

Tema 3: Instrumentos de medidas – Prof. Pedro

Breve descrição

Nós falamos aqui (anteriormente) sobre medidas auto-relatadas (subjetivas) e objetivas para o CS. Existe certa dificuldade em se medir a AF, e o mesmo acontece com o CS?

Breve descrição

O CS também têm sido associado negativamente com a saúde mental em diversas faixas etárias. Além disso parece que o tipo ou onde o CS acontece (domínios) parecem ter efeitos diferentes.
