There are well-known biological differences between women and men, especially in technical-coordinative variations that contribute to sex performance of complex movements like the most important offensive action volleyball, spike jump. The aim this study was investigate sex-dependent biomechanical characteristics volleyball Thirty female male sub-elite players were analysed while striking a stationary ball with maximal jump height. Twelve MX13 Vicon cameras cluster marker set, two AMTI force...

The objective was to estimate the reliability and criterion-related validity of Jump-and-Reach Test for assessment squat, countermovement, drop jump performance 32 male Brazilian professional volleyball players. Performance jumps with different dropping heights assessed on measurement flight time, then compared across trials. very high coefficients both methods lower correlation between scores assessments indicate a consistency each method but only moderate covariation, which means that they...

In performance testing, it is well-established that general jump types like squat and countermovement jumps have great reliability, but the relationship with volleyball spike unclear. The objectives of this study were to analyze between provide improved models for predicting height by performance. Thirty female male elite players performed in a randomized order. Two AMTI force plates (2000 Hz) 13 Vicon MX cameras (250 captured kinematic kinetic data. Correlation stepwise-forward regression...

Lower extremity kinetic data during walking of 12 people with chronic poststroke were reanalyzed, using functional analysis variance (FANOVA). To perform the FANOVA, whole curve is represented by a mathematical function, which spans gait cycle and avoids need to identify isolated points, as required for traditional parametric analyses (ANOVA). The power variables at ankle, knee, hip joints, in sagittal plane, compared between two conditions: With without sticks comfortable fast speeds. For...

importância deste programa e a necessidade de reforçar prática do aconselhamento com caráter preventivo promotor da saúde na Atenção Primária.

This cross-sectional study sought to analyze the associations between health conditions and inadequate consumption of fruit vegetables (FV) 1,255 men women attended in Primary Healthcare Units Belo Horizonte (State Minas Gerais). Data collection included FV consumption, socioeconomic status conditions. Results are presented by prevalence ratio (PR) with a confidence interval 95% (CI 95%). A 77.5% 95%: 75.1%-79.8%) inadequacy (< 5 daily servings) was found it more prevalent among (83.8%, CI...

O alongamento é uma prática comum no treinamento da flexibilidade, porém existe deficiência de informações específicas sobre os componentes carga utilizados, em especial, a intensidade do alongamento. presente estudo teve como objetivo investigar o efeito agudo duas diferentes intensidades na amplitude movimento (ADM) extensão joelho. Participaram deste 14 voluntários sexo masculino. Os dois membros inferiores cada participante foram avaliados, sendo que um membro executou submáxima (TS,...

The aim of the study was to verify level association between simple reaction time (RT) and movement (MT) young indoor soccer (futsal) players (13.8 ± 0.5 years, n = 16). Simple RT measured using Multipsy 821 apparatus with a button pressing as an answer light stimulus. MT, turning body left or right, by system composed contact carpet, fixed on ground, two pairs doubled-photocells. beginning registered loss carpet end recorded when player passed through pair distance first photocells 1.45 m....

The aim of this study was to present a new training algorithm using artificial neural networks called multi-objective least absolute shrinkage and selection operator (MOBJ-LASSO) applied the classification dynamic gait patterns. movement pattern is identified by 20 characteristics from three components ground reaction force which are used as input information for in gender-specific classification. performance between MOBJ-LASSO (97.4%) (MOBJ) (97.1%) similar, but achieved more improved...

Individual responses to different vibration frequencies identified by electromyography dynamometry in types of application. J Strength Cond Res 35(6): 1748-1759, 2021-The application mechanical is a common neuromuscular training technique used sports programs generate acute increases muscle strength. The principal aim the study was compare individual optimal frequency (IOVF) (EMG) activity force...

ABSTRACT Introduction: Muscular strength is an essential capacity for soccer players; however, the profile of this has not yet been clearly established in young players. Objective: To compare muscular performance countermovement jump (CMJ) task and presence lower limb asymmetry among athletes under 15 (U15), 17 (U17) 20 (U20) categories, between two teams different competitive levels. Methods: One hundred fifty one players three categories (U15, U17 U20) from Brazilian first second divisions...

Stretching exercises are able to promote adaptations in the muscle-tendon unit (MTU), which can be tested through physiological and biomechanical variables. Identifying key variables MTU is crucial improvements training.To perform an exploratory factor analysis (EFA) involving often used evaluate response of stretching exercises.Maximum joint range motion (ROMMAX), ROM at first sensation (FSTROM), peak torque (torqueMAX), passive stiffness, normalized energy, energy were investigated 36...

ABSTRACT Drop jump (DJ) performance an important aspect in many sports. The optimal stretch load the DJ training is commonly prescribed through box height from which individuals must drop from. However, studies have reported differences between real (calculated) heights and heights, may affect quality of prescription load. Other aspects such as individual stature also calculated heights. This study aimed to 1) investigate difference different 2) verify influence on Twenty-two performed DJs...

O objetivo do presente estudo foi mensurar a flexibilidade de crianças e adolescentes ambos os sexos (7 aos 15 anos idade), utilizando o teste Sentar-e-Alcançar (TSA) outro (Banco para Avaliação da Flexibilidade - BAFLEX) que possibilite controlar as influências das características antropométricas individuais. Participaram 250 escolares sexo masculino feminino, agrupados em cinco faixas etárias: 7, 9, 11, 13, anos. Quando testados pelo TSA, verificado um comportamento similar entre sexos,...
