Methods Thirty-one older adults participated in the study. They wore a GENEActiv Original on each wrist and performed nine activities of daily living. A portable gas analyzer was used to measure energy expenditure for each task. Testing was performed on two occasions separated by at least 8 days. Some of the same participants (n = 13) also wore one device on each wrist during 3 days of free-living. Receiver operating characteristic analysis was performed to establish the optimal cutpoints. Results For sedentary time, both dominant and non-dominant wrist had excellent classification accuracy (sensitivity 0.99 and 0.97, respectively; specificity 0.91 and 0.86, respectively). For Moderate to Vigorous Physical Activity (MVPA), the non-dominant wrist device had better accuracy (ND sensitivity 0.90, specificity 0.79; D sensitivity 0.90, specificity 0.64). The corresponding cutpoints for sedentary-to-light were 255 and 375 g · min (epoch independent 42.5 and 62.5 mg), and those for the light-to-moderate were 588 and 555 g · min (epoch-independent 98.0 and 92.5 mg) for the non-dominant and dominant wrist, respectively. For free-living data, the dominant wrist device resulted in significantly more sedentary time and significantly less light and MVPA time compared to the non-dominant wrist.This article is the result of an ethnographic work on baton twirling clubs in Switzerland clubs with few members coming from a modest origin, offering a social and physical activity with little resonance, composed of children, and young girls. The supervision is mainly the responsibility of close volunteers family members, friends or neighbors and, for the majority of them, women. It is therefore an environment where people
