This study aimed to identify the maturity-related differences and its influence on the physical fitness, morphological and performance characteristics of young elite paddlers. In total, 89 kayakers and 82 canoeists, aged 13.69 ± 0.57 years (mean ± s), were allocated in three groups depending on their age relative to the age at peak height velocity (pre-APHV, circum-APHV and post-APHV) and discipline (kayak and canoe). Nine anthropometric variables, a battery of four physical fitness tests (overhead medicine ball throw, countermovement jump, sit-and-reach test and 20 m multistage shuttle run test) and three specific performance tests (1000, 500 and 200 m) were assessed...

This study investigates test-retest reliability and diagnostic accuracy of the load release balance test under four varied conditions. Young, early and late middle-aged physically active and sedentary subjects performed the test over 2 testing sessions spaced 1week apart while standing on either (1) a stable or (2) an unstable surface with (3) eyes open (EO) and (4) eyes closed (EC), respectively. Results identified that test-retest reliability of parameters of the load release balance test was good to excellent, with high values of ICC (0...

The aim of this quasi-experimental pilot study was to explore the effects of a reformer Pilates program on the anthropometry, body composition, and somatotype of active adult women after a short non-exercise period. Twenty-eight women (mean age: 40.21 ± standard deviation of 8.12 years old) with one to three years of reformer Pilates experience participated in the study. The women participated in a reformer Pilates program for 16 weeks (one hour, twice per week) after 4 weeks of detraining (summer holidays) in 2012...

INTRODUCTION: lumbo-sacral posture and the sit-andreach score have been proposed as measures of hamstring extensibility. However, the validity is influenced by sample characteristics. OBJECTIVE: to determine the validity of lumbo-horizontal angle and score in the sit-and-reach test as measures of hamstring extensibility in older women. METHOD: a hundred and twenty older women performed the straight leg raise test with both leg, and the sit-and-reach test (SR) in a random order...

The aims of this study were to describe and compare kinanthropometric characteristics of elite young kayakers and canoeists and to compare their proportionality with Olympic paddlers. One hundred and twenty young elite sprint paddlers (66 kayakers and 58 canoeists), aged 13- and 14-years-old, were assessed using a battery of 32 anthropometric dimensions. Somatotypes, Phantom Z-scores and corrected girths were calculated. Comparison between kayakers and canoeists showed that kayakers had greater height, body weight, sitting height, arm span and upper body lengths, breadths and girths than canoeists...

BACKGROUND AND OBJECTIVE: Systematic repetition or prolonged posture in specific postures adopted during training could generate modifications on the sagittal spinal curvatures. Spinal alteration in its physiologic curvatures in the sagittal plane has been associated with predisposition to spinal disorders. The objective was to evaluate and compare the changes produced on the sagittal thoracic and lumbar spinal curvatures, and pelvic tilt from standing posture on the floor to upper, middle, lower and aerodynamic handlebars postures adopted on their own road bicycles...

INTRODUCTION: Dietary habits and body composition are possibly two of the most modifiable aspects that influence athletic performance in competition and training, especially in individual sports. OBJECTIVE: To determine Mediterranean diet adherence in a group of elite women paddlers and the relationship between these variables with anthropometric parameters and somatotype of the athlete. METHODS: A 90 women cadets who belonged to the national elite canoeing underwent a complete anthropometry according to ISAK instructions; and they selfcompleted KIDMED test to know their adherence to the Mediterranean diet...

The objective of this research was to determine the kinematic variables evolution in a sprint canoeing maximal test over 200 m, comparing women and men kayak paddlers and men canoeists. Speed evolution, cycle frequency, cycle length and cycle index were analysed each 50 m section in fifty-two young paddlers (20 male kayakers, 17 female kayakers and 15 male canoeists; 13-14 years-old). Recordings were taken from a boat which followed each paddler trial in order to measure the variables cited above. Kinematic evolution was similar in the three categories, the speed and cycle index decreased through the test after the first 50 m...

Sports with a predominance of forward-bending and extension postures have been associated with alterations in the sagittal spinal curvatures and greater risk of spinal injury. Because, the tennis players adopt these postures, the aims of this study were: 1) to describe spinal curvatures and pelvic tilt in male and female highly trained adolescent tennis players during relaxed standing posture and with thoracic spine corrected (in prone lying on the floor); and 2) to determine the frequency of thoracic hyperkyphosis and lumbar hypo/hyper lordosis in these postures...

INTRODUCTION: Nowadays, in developed countries there are standards of beauty based on pro-thin models, which are internalized by adolescents and young people especially in the case of women, assuming it as risk factor for developing changes in body image and perception. OBJECTIVE: To analyze the current state of research in relation to body image, the sociodemographic variables that influence it, the relationship between body composition, conducting diets, eating disorders, sports and intervention programs and prevention, and the body image...

The objective of this study was to determine the sagittal spinal curvatures and pelvic position in standing and kneeling in the canoe in young canoeists. Forty-four young highly-trained canoeists (mean age: 15.11 ± 0.61 years) were recruited. Thoracic and lumbar curvatures and pelvic inclination were evaluated with a Spinal Mouse system in standing position and in the base position (kneeling on one knee in the canoe) and catch phase of the stroke. The mean thoracic kyphosis, lumbar lordosis and pelvic inclination in standing were 44...

The purpose of this study was to determine the influence of different sizes of hand paddles on kinematic parameters during a 100 m freestyle swimming performance in elite swimmers. Nine elite swimmers (19.1 ± 1.9 years) completed three tests of 100 m without paddles, with small paddles (271.27 cm(2)) and with large paddles (332.67 cm(2)), respectively. One video camera was used to record the performance during the three trials. The mean swimming velocity, stroke rate and stroke length were measured in the central 10 meters of each 50 m length...

The aim of this study was to determine acute effects of hamstring stretching in thoracic and lumbar spinal curvatures and pelvic tilt. Fifty-five adults (29.24 ± 7.41 years) were recruited for this study. Subjects performed a hamstring stretching protocol consisting of four exercises. The session consisted of 3 sets of each exercise and subjects held the position for 20 seconds with a 30-second rest period between sets and exercises. Thoracic and lumbar spinal angles and pelvic tilt were measured with a SpinalMouse in relaxed standing, sit-and-reach test and Macrae & Wright position...
