Changes in physical activity and fitness after 3 months of home Wii Fit™ use.

The purpose of this study was to examine changes in physical activity and fitness variables in members of 8 volunteer families after 3 months of home use of the Wii Fit™ interactive video game. Pre and postintervention measurements were obtained from 21 subjects relative to physical activity (5 days of accelerometry), aerobic fitness (graded treadmill test), muscular fitness (push-ups), flexibility (sit-and-reach test), balance (composite equilibrium score), and body composition (body mass index and % body fat). Use characteristics of the Wii Fit™ device were also determined.

Density-dependent habitat selection and performance by a large mobile reef fish.

Many exploited reef fish are vulnerable to overfishing because they concentrate over hard-bottom patchy habitats. How mobile reef fish use patchy habitat, and the potential consequences on demographic parameters, must be known for spatially explicit population dynamics modeling, for discriminating essential fish habitat (EFH), and for effectively planning conservation measures (e.g.

Body water indices as markers of aging in male masters swimmers.

The association of age and weekly swim training distance with body water, lean tissue, fat mass and regional adiposity was examined in 27 male masters swimmers. Subjects ranged in age from 25.3 to 73.

Safety, feasibility, and efficacy of a resistance training program in preadolescent obese children.

Background: Safe and effective exercise programs are needed to prevent and treat chronic diseases in childhood. In particular, preadolescent obese children should participate in activities that are specific to their special needs. Resistance or strength training has been prescribed for adult obese persons.

Inclusion of resistance exercise in a multidisciplinary outpatient treatment program for preadolescent obese children.

Background: Safe and effective exercise programs are needed to prevent and treat chronic diseases in childhood. In particular, preadolescent obese children should participate in activities that are specific to their special needs.

Methods: We included a moderate intensity, progressive resistance training program in a multidisciplinary weight management program for obese preadolescent children.
