Management and teaching methodology of swimming lessons in the Portuguese prima...

The aim of this study was to describe the management and the teaching methodology in the primary level Physical Education classes in Portugal to teach swimming motor skills. The sample included 89 public swimming-pools supervisors and 100 swimming teachers. In order to assess the management and the teaching methodology, two questionnaires were used and their results were described based on descriptive statistic...

Peak career in world-ranked swimmers: age’s analysis of 2008 Beijing Olympic Ga...

The aim of this paper was to: (i) describe the Beijing 2008 Olympic Games swimmer’s ages and; (ii) compare ages according to swimmer’s gender. It was analyzed 1101 inscriptions (588 men and 513 women) for all swimming events held at the Beijing 2008 Olympic Games: 50 meters freestyle (L50), 100 meters freestyle (L100), 200 meters freestyle (L200), 400 meters freestyle (L400), 800 meters freestyle (L800, only wo...

PERFORMANCE DE VIRAGEM E FORÇA DOS MEMBROS INFERIORES EM NADADORES DE GRUPOS DE...

Uma prova de natação é composta por quatro momentos fundamentais e indissociáveis: (i) a partida; (ii) o nado propriamente dito; (iii) a viragem (Hay,1988) e a (iv) chegada (Arellano, 1993; Maglischo, 2010), onde cada detalhe técnico e/ou tático é relevante e influenciador da performance do nadador. Assim, é expetável que os treinadores incidam semelhante atenção a estes pormenores nas suas unidades de treino. ...

Differences in swimming force metrics induced by gender

Swimming performance differences are notorious among male and female post-puberty swimmers. Previous studies point that, in adolescence, boys are taller and heavier than girls; taking advantage in swimming performance with that anthropometric difference (Morouço et al., 2012). Therefore, the aim of this study was to identify possible differences between performance (personal best at 50m freestyle) and parameter...

Relationship of force metrics with swimming performance in age-group swimmers.

Introduction In competitive swimming, performance relies in the good combination of force and technique. The relative contribution of each of these components is still a controversial issue. Therefore, the aim of this study was to verify if force metrics obtained through tethered swimming can be explanatory of free swimming performance. Methods 22 age-group swimmers (male n=14, age: 14.6±1.2years of age, body ...

Frequência cardíaca, perceção subjetiva de esforço e lactato sanguíneo nas aula...

O objetivo deste estudo foi comparar as respostas da frequência cardíaca (FC), perceção subjetiva do esforço (PSE) e da concentração de lactato (LA) nas aulas de jump fit e hidro jump. A amostra foi constituída por 8 mulheres (43.5 ± 5.2 anos, 160.0 ± 4.68 cm, 58.93 ± 4.15 kg e 25.69 ± 4.40 %MG), todas elas praticantes das aulas de fit jump. O estudo envolveu três momentos de avaliação. Na primeira foram avalia...

Shoulder rotator isokinetic strength profile in young swimmers

Considering that some studies suggest that shoulder rotators muscle imbalances are related to joint pain and injury, and that there are no normative data for young swimmers, the aim of this study was: i) to describe the muscle balance, fatigue and isokinetic strength profile of the shoulder rotators in young swimmers; ii) to compare the results between swimmers and a group of young non-practitioners; iii) to co...

Water training effect in shoulder rotators strength in young swimmers

INTRODUCTION The purpose of this study was to evaluate the effect of 18 weeks water training on the rotator cuff strength of young swimmers. METHODS Twenty Portuguese national level male swimmers (age: 14.60±0.67 years old, height: 170.79±6.48 cm, body mass: 61.73±4.68 kg) and 16 sedentary male students (age: 14.88±0.72 years, height: 168.38±6.19 cm, body mass: 60.84±11.69 kg) participated in this study. The pe...

Infants’ Behaviours During Aquatic Activities

INTRODUCTION In the last decades an increasing participation of infants in aquatic activities has been noticed. Although that increasing interest, the research about infant swimming is quite rare. The interest around infants’ behaviours during a swimming session allows characterizing or estimating the physical demand and its responses to basic aquatic motor skills (Richards and Gibson, 2006). The aim of this st...
