Background: Resuming a physical exercise program after period of cessation is common in older women. Monitoring the responses during this detraining (DT) and retraining (RT) may allow us to analyze how body reacts an increase reduction inactivity. Therefore, we conducted follow-up training, DT, RT prehypertensive women response these periods. Methods: Twenty-three (EG; 68.3 ± 2.8 years; 1.61 0.44 m) performed 36 weeks multicomponent training (MTP) followed by twelve DT plus eight RT. Fifteen...

<p>A atividade física proporciona benefícios para a saúde e qualidade de vida mulheres idosas. Ainda são escassos os estudos longitudinais em idosas com duração superior um ano prática exercício físico. Assim o objetivo do estudo foi analisar efeitos três anos treino multicomponente na capacidade funcional Métodos: 51 (66.7±5.30 159±0.11cm) participaram ao longo num programa constituído por períodos nove meses seguidos destreino. As avaliações decorreram no início/fim cada período...

To investigate the arm-leg coordination from different perspectives of motor control during underwater start sequence to understand whether differences exist between three competitive breaststroke swimming events.Cross-sectional study.Forty-one races (with race times relative world record): 50-meter (n = 14, 87.6%), 100-meter 88.5%) and 200-meter 13, 85.4%) were recorded. A analysis system tracked two-dimensional displacement head. Key points obtained notational in order compute seven...

The purpose of the present study was to investigate intra- and inter-individual variability in arm-leg coordination during underwater phase turn segment 200 m breaststroke. Thirteen male swimmers were recruited performed a breaststroke pre-calibrated 25 pool. Sub-phases obtained using notational analysis, mean velocity, displacement duration each sub-phase obtained. A hierarchical cluster analysis (HCA) analysed variables all phases identify random intra-individual variability. In addition,...

Abstract The purpose of this paper was to examine the characteristics waves generated when swimming with and without use Aquatrainer® snorkels. Eight male swimmers performed two maximal bouts 25 m breaststroke, first a snorkel (normal condition) then using (snorkel condition). body landmarks, centre mass velocity, stroke rate, length, index, Strouhal number (St) were quantified. Fourier analysis conducted determine frequency, amplitude, phase vertical undulations. We also determined...

OBJETIVO: Caracterização da técnica de bruços, na relação entre os parâmetros cinemáticos e neuromusculares. MÉTODO: A eletromiografia superfície (EMG) foi utilizada para analisar a dinâmica atividade neuromuscular nos músculos peitoral maior (PM), bicípite braquial (BB), tricípite (TB) deltoide anterior (DA) em 12 nadadores elite nacional. Foi utilizado um par câmaras, fornecendo uma projeção dupla partir câmara subaquática outra acima água, análise das variáveis cinemáticas: velocidade...

Abstract The purpose of this study was to analyse swimmers’ perceptual judgements a simulated time‐to‐contact task in freestyle swimming relays. sample consisted 31 national‐level swimmers both genders ( n = 18 males, 17.22 ± 1.95 yrs.; 13 females, 14.61 .76 yrs.). Participants were asked watch two videos corresponding the last course given swimmer during competition 4 × 100 m and 200 events. These presented with temporal occlusion correspondent predetermined approaching distances (7.5, 5.0,...

The need to develop systems electromyographic (EMG) in the aquatic environment, has led several researchers refine these instruments ensure credibility of data provided by EMG.The aim this study is characterize behavior two muscle muscles involved crawl technique (biceps brachii and triceps brachii) over a test 200m crawl.1 male swimmer trained was subjected consisting maximum voluntary contraction (MVC) Biceps Brachii (BB) Triceps (TB) for standardization.A protocol 4 x 50m with an interval...

In breaststroke races, the dolphin kick could finish before, at same time, or during arm pull-out, but it is unclear how swimmers perform this technique. The aim of study was to investigate whether glide between and favour continuity even overlap those two phases, as would impact active underwater sequence. Fourteen international national male performed 100-m with all-out effort in a pre-calibrated 25 m swimming pool. A multi-camera system tracked head swimmers. Key points sequence were...

The purpose of this study was to analyze the acute effects a standardized water training session on shoulder rotators strength and balance in age group swimmers, order understand whether muscle-strengthening workout immediately after is appropriate. A repeated measures design implemented with two measurements performed before swim session. 127 participants were assembled male (n = 72; age: 16.28 ± 1.55 years, height: 174.15 7.89 cm, weight: 63.97 6.51 kg) female 55; 15.29 1.28 163.03 7.19...

Judo is an Olympic combat sport that divided into male and female weight categories. Each category implies significant differences in technical strategic dimensions, as well physiological, performance, body composition among competitors. This study aimed to determine the actions predominance used by judokas European Championship 2021. We observed 398 judo combats, various categories female, disputed It was observation system accordance with classification of techniques proposed Kodokan. An...

Construction work is physically demanding. The tasks involved in this professional occupation exhaust workers and put them at high risk of injury. This aimed to analyze muscle fatigue civil construction with without a history physical activity. For purpose, the activity biceps femoris, trapezius transversalis, erector spinae longissimus muscles was evaluated using surface electromyography. Eleven male aged 26 52 years (38.00 ± 9.60), seven whom were untrained (N = 7) four trained 4),...

Abstract Background It is known that atipical aging in DS related to a high risk of early dementia, with neuropathological charactheristics compatible Alzheimer´s disease (AD). Changes functional mobility are expected throughout the process, impairments motor performance, involving balance and gait. Growing evidence suggests sleep disruption may also accelerate progression symptomatic Alzheimer’s (AD) this population. Therefore, it mandatory assess quality diagnose sleep‐disordered...
