A simple field test to assess endurance in inexperienced runners.

The accuracy of a simple field test, the 3-minute, 30-second endurance capacity test (3'30'' ECT), was evaluated in 12 moderately trained athletes. It consisted of 10 3-minute running bouts, separated by 30-second passive recoveries. The first 5 bouts were performed at 75% of maximal aerobic speed (MAS, which was previously determined), and the last 5 were at a self-selected speed.

Arm coordination adaptations assessment in swimming.

The link between modifications in arm coordination (IdC) and intracyclic velocity variation (IVV) as a function of swim pace and gender is investigated. Twelve elite swimmers performed 5 different swim paces. Video analysis allowed IdC determination.

Comparison of spatio-temporal, metabolic, and psychometric responses in recreational and highly trained swimmers during and after a 400-m freestyle swim.

Spatio-temporal, metabolic and psychometric responses during and after a 400-m freestyle swim trial were investigated for gender and skill-level effects. Thirty-four men and women, 18 national and international competitors and 16 recreational swimmers, were compared. Mean speed, stroke rate (SR), and stroke length (SL) were obtained from video recordings.
