Fourteen male futsal players (16.5 ± 0.51 years, 67.5 ± 11.1 kg; 1.73 ± 0.08 cm; 22.5 ± 2.3kg/m²) from a youth futsal team took part at the study. Our research monitored the team throughout the 4-day qualifying phase of the Campeonato Paranaense de Futsal (the Youth Futsal Championship of the State of Paraná, Brazil). The athletes underwent the following tests immediately after each futsal match: vertical jump test (Squat Jump (SJ)), Countermovement Jump test (CMJ), and a rating of perceived exertion (s-RPE) session. Magnitude based inference analysis reported CMJ values likely lower after the 2nd match when compared with the results obtained after the 1st and 4th matches: (ES= -0.46 low) and (ES= -0.53 moderate), respectively. Furthermore, SJ values reported after the 2nd match are likely lower if compared with the outcomes obtained af...

This pre-post study design was performed during a typical 10 weeks training period. HIIT sessions were conducted at 86% (HIIT86; n = 6) and 100% (HIIT100; n = 5) of peak speed of the FIET. Additionally, friendly and official matches, technical-tactical and strength-power training sessions were performed. Before and after the training period, all players performed the FIET, treadmill incremental, repeated sprint ability (RSA), sprint 15-m, and vertical jump tests (CMJ and SJ), and the HRV was measured. Training load (TL) was monitored using ...

Methods: Eleven male competitive cyclists (age: 30.3 ± 4.7 years; body mass: 73.7 ± 7.7 kg; body fat: 11.3 ± 4.2%) were submitted to two sessions of the Wingate test (WT) in different positions, on different days. Results: The peak power (W), average power (W), relative peak power (W•kg-1), relative average power (W•kg-1), average cadence (rpm), and average velocity (km•h-1) presented significant differences in the standing position compared with the seated position (p < 0.05),

Cinquenta e três atletas do sexo masculino participaram do estudo divididos entre as categorias sub-11 (n=17; idade=10,6 ± 0,5 anos), sub-13 (n=16; idade=12,3 ± 0,4 anos), sub-15 (n=11; idade= 14,2 ± 0,4 anos) e sub-17 (n=9; idade= 16,6 ± 0,5 anos), e realizaram duas visitas: a primeira consistiu em avaliações antropométricas com massa corporal, estatura e dobras cutâneas, e questionário do estado pubertário; e a segunda visita foi avaliada a produção de potência aeróbia realizada com um teste progressivo com 5 séries de corrida vai-e-vem de 12 segundos, com 6 segundos de repouso, até a exaustão voluntária. A distancia inicial do teste foi de 15 metros, com aumentos de progressivos de 1 metro a cada série, a maior velocidade atingida no teste (km.h-1) foi det...

Participaram da pesquisa 53 atletas de ambos os sexos, com idades entre 13 e 21 anos. Foi utilizado o "Situações de Stress no Handebol" (SSH), além de uma pergunta aberta. Foram calculadas a freqüência e porcentagem de respostas "sim" dadas a cada um dos itens do SSH. Quanto à pergunta aberta, as situações de jogo encontradas foram agrupadas em categorias de respostas denominadas fontes de estresse. Percebeu-se que, dos cinco principais itens considerados estressantes por cada um dos grupos, quatro foram comuns a ambos. Apesar da distância que separa as regiões, ocorreram semelhanças na percepção das situações estressantes durante o jogo.

For this, 26 male athletes were evaluated. Anthropometric variables were: body mass, standing and sitting height, and length of lower limbs. Maturation was determined by age at PHV. Physical performance was determined by lower limb power (counter movement jump - CMJ) and aerobic power (Intermittent Recovery Test) tests. MANOVA reported significant differences (p<0.05) among playing positions regarding variables Maturity Offset, estimated PHV age, standing height, sitting height, estimated leg length, body mass and Yo-Yo IR1. In addition, it was identified that point guards reached estimated PHV at later age than their peers who act as small forwards and c...

Anthropometric and body composition variables were obtained according to international criteria. Biological maturation was determined by age of PHV and for the purpose of analysis, it was categorized into developmental levels. The results reinforce, as expected, an increasing trend of variables analyzed as students advanced in maturity. hus, it was concluded that with the advancement of maturation, anthropometric variables maintain a linear growth observed in each PHV stratum. his linear trend is not observed in body composition. Body fat showed a decrease in average values as the individual approaches PHV.

The aims of this study were to compare the session rating of perceived exertion training load (s-RPE TL) during the preseason between two teams; and to analyze the changes on the delayed-onset muscle soreness (DOMS), aerobic- and speed-power characteristics in players accumulating different s-RPE TL (Low (LTL) vs. High (HTL)). Twenty-eight players (Team A, n = 15; Team B, n = 13) were recruited. The s-RPE TL was monitored throughout the preseason phase (five weeks) in both teams. The coaches of each team planned the activities that comprised their training programs, without any interference from the researchers. Team A evaluated countermovement jumps (CMJ) and DOMS weekly. Team B performed squat jumps (SJ), CMJ, 5 m and 15 m sprints, and a futsal intermittent endurance test (PVFIET) before and after the preseason. Team B accumulated an almost-certainly greater...

The purpose of this study was to examine whether elite futsal players demonstrate strength asymmetries during knee isokinetic testing applying the Croisier et al.21 criteria. Forty male elite (27.9 ± 6.5 years) Brazilian futsal players participated in the study. The testing protocol required players to perform concentric contractions of both quadriceps and hamstring muscles at angular velocities of 60 °·sand 240 °·sand eccentric contractions of hamstring at 30 °·sand 120 °·s. Conventional (concentric:concentric) and mixed (eccentric:concentric) hamstrings/quadriceps (H/Q) ratios were calculated. Subjects were determined to have an imbalanced strength profile if an athlete had at least two parameters that were asymmetrical across speeds and conditions. Asymmetry was operationally defined as peak torque asymmetry greater than 15% in bilateral comparison, and H/Q ratio less than 0.47 for conventional and ...

Onze atletas de basquetebol (17,3±0,8 anos) e doze atletas de handebol (16±0,8 anos) foram submetidos a avaliação antropométrica, questionário pubertário, teste de Capacidade de Sprints Repetidos (CSR) e teste de Carminatti (T-CAR). Foram encontradas diferenças significativas na idade e no tempo médio (CSR) entre os atletas. Entretanto, o T-CAR e o nível maturacional não foram encontradas diferenças. Desta forma, torna-se viável aplicar testes de potência aeróbia e anaeróbia similares para ambas as modalidades, porém, é importante controlar os níveis maturacionais.
