Insufficient data on adolescent athletes is contributing to the challenges facing youth athletic development and accurate talent identification. The purpose of this study was to model the progression of male sub-elite swimmers’ performances during adolescence. The performances of 446 males (12–19 year olds) competing in seven individual events (50, 100, 200 m freestyle, 100 m backstroke, breast...

The present work proposed to study the oxygen uptake slow component (VO2 SC) of breaststroke swimmers at four different intensities of submaximal exercise, via mathematical modeling of a multi-exponential function. The slow component (SC) was also assessed with two different fixed interval methods and the three methods were compared. Twelve male swimmers performed a test comprising four submaxi...

The different characteristics of the four swimming strokes affect interplay between limbs, acting as a constraint to force produced by each hand and foot. purpose this study was analyze symmetry production with varying number limbs in action see its effect on velocity. Fifteen male swimmers performed all-out bouts 25-m swims full-body stroke segmental actions. A differential pressure system use...

background: to determine the effects of probiotic yogurt on performance and health status of young adult female endurance swimmers.   methods: in a randomized controlled trial, 46 endurance swimmers girls with mean age of 13.8 ±1.8 years, weight of 48.6±7.5kg and height of 159±5.6cm, were studied. subjects were randomly assigned into two groups, receiving either 400 ml probiotic yogurt (interve...

ABSTRACT Background: Objective: The study of sports biomechanics in medicine usually requires a special image analysis system (software) to obtain 3D kinematics data. Taking the swimming project as an example, water images have always been relatively complicated and difficult. As light travels different media, it will refract reflect. When testing underwater movements, if only land camera or is...

The increased participation of master athletes (i.e., >40 years old) in endurance and ultra-endurance events (>6 h duration) over the past few decades has been accompanied by an improvement in their performances at a much faster rate than their younger counterparts. Aging does however result in a decrease in overall endurance performance. Such age-related declines in performance depend upon the...

Studies of locomotor performance have contributed to the elucidation of how suborganismal traits ultimately relate to fitness. In terrestrial populations, exploring the physiological and environmental contributions to whole-animal performance measures has improved our understanding of phenotypic selection. Conversely, very little is known about the links between phenotypic selection and swimmin...
