Why prolonged sitting silences muscle activity and how to counteract it

A new study has found that sitting continuously for 25 minutes significantly reduces thigh muscle activity, raising concerns about the health risks associated with prolonged inactivity.

According to Natural News, the research examined 84 adults across 7,684 sitting periods using wearable technology to monitor muscle activity.

The findings revealed that thigh muscle activity reached its lowest levels after 25 minutes of uninterrupted sitting.

Researchers observed that individuals who remained seated for longer periods experienced reduced muscle engagement compared to those who took frequent movement breaks.

The study also suggested that walking before sitting helped maintain greater muscle activity than standing still.

Separate research involving 20 adults with obesity found that moving their legs while seated improved blood sugar regulation and insulin responses.

Researchers recommended taking short walking breaks approximately every 25 minutes to reduce prolonged muscle inactivity.

They noted that regular movement could support metabolic health, although the findings do not establish that 25 minutes is a universal health threshold.
