Fin type and flutter technique: a study to optimise the oxygen consumption in divers.

The purpose of this research was to assess the variability of the oxygen consumption (VO) depending on fin type and the flutter technique used for the different divers' profile. Twenty-three SCUBA divers took part in four 2.5 hour sessions to evaluate a total of six fin models and two flutter techniques.

Effects of a moderate-to-high intensity resistance circuit training on fat mass, functional capacity, muscular strength, and quality of life in elderly: A randomized controlled trial.

Physical exercise is considered an important intervention for promoting well-being and healthy aging. The objective was to determine the effects of moderate-to-high intensity resistance circuit training on different parameters of body composition, functional autonomy, muscular strength and quality of life in elderly. A randomized controlled trial was conducted.

Relationship between motor variability, accuracy, and ball speed in the tennis serve.

The main objective of this study was to analyze the motor variability in the performance of the tennis serve and its relationship to performance outcome. Seventeen male tennis players took part in the research, and they performed 20 serves. Linear and non-linear variability during the hand movement was measured by 3D Motion Tracking.
