Physical activity using wrist-worn accelerometers: comparison of dominant and non-dominant wrist.

The purpose of this study was to determine whether there is a difference in physical activity assessment between a wrist-worn accelerometer at the dominant or non-dominant arm. The secondary purpose was to assess the concurrent validity of measures of physical activity from the wrist-worn accelerometer and the waist-worn accelerometer. Forty adults wore three accelerometers simultaneously, one on the waist and one each on the non-dominant wrist and dominant wrist, respectively, for 24 consecutive hours of free-living conditions.

Relationship between tactics and energy expenditure according to level of experience in badminton.

Research on racket sports has traditionally focused on expert players and has treated energy expenditure and tactics as independent factors. These prior studies could not assess how energy expenditure and tactics changed as a function of experience and skill. Here, the specific relationship between playing tactics and energy expenditure in badminton were assessed.

Influence of sleep timing behavior on weight status and activity patterns in adults with intellectual disabilities.

The aim was to explore the relationship between sleep habits and overweight/obesity, physical activity and sedentary behaviors in French adults with intellectual disabilities. This observational study was conducted on 570 French adults with intellectual deficiency. Sleep habits were analyzed and related to anthropometric measures, physical activity and sedentary behaviors.

Strategies in intervention programmes for obese youth: implication of the age and the type of physical activities.

The aim of this study was to assess the effects of age and type of physical activity on anthropometric measures of obese youth participating in an intervention programme. Subjects included 37 obese children (12·5 ± 2·9 years). The programme consisted of a unique programme of physical activity and health education.

Overweight in intellectually-disabled population: physical, behavioral and psychological characteristics.

Intellectually disabled (ID) people are at high risk of overweight and obesity. Prevalence and risk factors were assessed in a French population of ID adults attending specialized institutions, using a questionnaire focusing on demographic characteristics, physical activities, food habits and self-awareness about body and health. Data analysis included descriptive statistics, univariate and multivariate regression.
