Scientists say that Fibion accelerometer demonstrated good to excellent validity in non-exercise physical activity.

The findings, published in the Heliyon journal, were the outcome of research the University of Sharjah's scientists conducted on 29 healthy adults.

“The research is the first of its kind to compare the validity of the Fibion and ActivPal4 accelerometers in estimating sedentary and upright times in individuals," the authors write in their paper.

“The Fibion demonstrated good to excellent validity in measuring sedentary and upright times," they add.

Both Fibion and ActivPal4 are accelerometer-based wearable devices used to measure physical activity levels and determine the time spent in different physical intensities.

The devices are worn on the thigh. They measure postures like sitting and standing with better precision than devices worn on the waist.

The study examined time the participants spent sitting, walking, and standing during a typical weekday.

The Fibion's validity was compared to ActivPal4 as it has been the reference standard for measuring accurate sedentary and upright duration of postures.

The participants in the study wore both devices on the same thigh.

The sample size of the participants was in line with previous validity studies conducted on accelerometers.

The finding proves that the Fibion could be a good alternative to ActivPal4 in measuring these movements among healthy individuals.

In recent years, wearable accelerometers have gained mass popularity among consumers for their ability to measure physical activity, exercise intensity, sleep times, as well as identify any underlying health issues.
