“…O registro do tempo foi realizado a cada esforço (Timex, modelo 85103). Utilizou-se o índice de fadiga obtido pelo RAST como indicador para a resistência anaeróbia (Kalva-Filho et al, 2013). Quanto menor o índice de fadiga (IF), maior a resistência anaeróbia.…”

RESUMOO objetivo da investigação foi analisar o efeito do tipo de polimento sobre a resistência anaeróbia em jovens atletas de basquetebol do sexo masculino. Trata-se de uma investigação com duração de 12 semanas, desenvolvida com 47 basquetebolistas, divididos randomicamente em três grupos: polimento linear (GL), polimento por etapa (GE) e grupo de controle (GC). Todos os grupos fizeram a mesma planificação de treinamento até às últimas três semanas da periodização (fase do polimento). Somente o GC não realizou polimento. Utilizou-se o Running Anaerobic Speed Test na última semana de cada mesociclo a fim de avaliar a resistência anaeróbia. Os achados revelaram que a resistência anaeróbia atenuou do período competitivo para o polimento no GL (p= .01) e GE (p= .01), fato não verificado para o GC (p= .29). Identificou-se diferença significativa da resistência anaeróbia entre GL e GC (p= .01), GE e GC (p= .01) e entre GL e GE (p= .04) na etapa do polimento. Concluiu-se que as estratégias de polimento foram eficientes para maximizar a resistência anaeróbia de jovens atletas de basquetebol, embora a estratégia de polimento linear tenha revelado uma maior melhora na resistência anaeróbia quando comparada a estratégia de polimento por etapa.

This was an experimental research with 12 weeks, developed with 47 basketball players, randomly divided into three groups: linear tapering (LG), tapering by step (SG) and control group (CG). All groups participated of the same planning training until the last three weeks of periodization (the tapering phase). Only the CG did not perform tapering. Anaerobic Running Speed Test was carried in the last week of each mesocycle to assess the anaerobic capacity. The findings revealed that anaerobic capacity attenuated from the competitive to tapering phase in LG (p= .01) and SG (p= .01), which was not verified for the CG (p= .29). Significant difference of anaerobic capacity was found between LG and CG (p= .01), SG and CG (p= .01) and between LG and SG (p= .04) in the tapering phase. It was concluded that the tapering strategies were efficient to maximize anaerobic capacity in young basketball players, although linear tapering strategy has been revealed the best strategy for improvement the anaerobic capacity.

“…Tests like Wingate 6 , that uses short distances like 10 or 20 meters sprints and RAST -Running Anaerobic Sprint Test 7 are used to evaluate anaerobic power in sports. Due to its characteristics, RAST is widely used in disciplines where technical expertise is needed when using intermittent running on its practice [8][9][10] , confirming the specificity principle 11 . Besides that, RAST results allow obtaining the fatigue index from the athlete to monitor physical conditioning 12 .…”

“…Although several studies have shown the influence of different types of soil on physical exercise intensity, helping on the training prescription to court sports played on hard floors (basketball, volleyball, futsal, and handball), on grass (soccer) and sand (beach soccer, beach volley, and beach hand) 9,[13][14][15][16] , few studies addressed the influence of the type of soil on performance and fatigue index on RAST. It is an efficient method to evaluate anaerobic power on athletes and physically active individuals, allowing better conditions to physical and sports training programs.…”

Due to the high intensity of competitive sports, the anaerobic power is a very important physical capacity for most sports. However, the diverse surfaces were these sports may interfere in the performance of this capacity. In running-based sports, the Running Anaerobic Sprint Test – RAST is largely used to evaluate anaerobic power. Considering the specificity of each sport, it is suggested to apply this test on the surface that it is played. Thus, the aim of the present study is to analyze the performance of RAST on different surfaces. The sample was composed by 10 subjects, mean age 20.2 ± 0.9 years old, mean height 1.8 ± 0.1 meters, mean body weight 77.4 ± 15.9 kg, and practice time of 6.0 ± 2.0 years. RAST was conducted on three different surfaces (hard, grass and sand). The maximum and minimum power and the fatigue index were compared between the surfaces. The results indicate that maximum and minimum power were lower in sand when compared to grass and hard surfaces. However, the fatigue index did not change. So, we observed that the surface is an important factor in RAST performance.

“…Entretanto, utilizaram do mesmo modelo de RSA e encontraram diferenças apenas no tempo entre o esforço 1 e o esforço 12 (17%). Kalva-Filho et al (2013) O metabolismo aeróbio é predominante na fase de recuperação após cada esforço intenso, acionando a ressíntese de PCr e a remoção de metabolitos (GLAISTER, 2005;BAILEY et al, 2009). A recuperação rápida dos estoques de PCr intramusculares é feita nos primeiros instantes de pausa no exercício, que pode ser mensurada pelo componente rápido do consumo de oxigênio (PAN et al, 1991;SAHLIN, 1992…”

retirada (V y RET ) no primeiro esforço (p < 0,05). Desse modo, pode-se concluir que o RAST altera a mecânica de corrida e, além disso, o θtorn e CMz STD pareceram ser fundamentais e influenciam diretamente no desempenho deste modelo. Em terceiro lugar, foram encontradas mudanças no Spring-Mass Model (SMM) durante o RAST. A força máxima vertical do CM (F Z MAX ) diminuiu (-10,3%; p < 0,05). O deslocamento vertical do CM (∆ Z ) aumentou (+60,5%; p < 0,01). Vertical Stiffness diminuiu (-42,9%; p < 0,01) e a Leg Stiffness, não mudou. A contração voluntária máxima (CVM) de extensão de joelho (-4,4%) e a ativação voluntária (AV%) (-8,5 %) não mudaram (p > 0,05), mas foram evidenciadas correlações entre da PP com a razão RMS / M wave (r = -0,70), a PM e RMS (r = -0,77) juntamente com a razão RMS / M wave (r = -0,75) no VL. Dessa forma, pode-se concluir que a redução do desempenho e as alterações no comportamento do esforços repetidos, dos padrões de movimento, e do SMM, podem estar fortemente ligadas às respostas neuromusculares periféricas.

Abstract The aim of this study was to determine the physiological behavior, biomechanical and fatigue process in Running Anaerobic Sprint Test (RAST). Sixteen individuals (mean ± SD, 22.1 ± 3.1 years, body weight 78.6 ± 22.9 kg and height 186.1 ± 10.1 cm) were volunteers for this study. Participants underwent biomechanical, physiological monitoring and neuromuscular evaluations. In all cases it was made a warming-up by 5 min. After 120 s, underwent six maximal efforts of 35 m separated by 10 s passive rest (RAST). During efforts, two cameras captured the performance by kinematic bidimensional analysis while another 12 cameras were positioned to kinematic tridimensional analysis at 25 -35 m of each effort, after efforts were determined the concentrations of lactate ([Lac]). The TIP technique (Twitch Interpolation) was used for neuromuscular evaluations. The performance showed a difference from the fifth (5.1 ± 0.1 s) and sixth effort (5.4 ± 0.3 s; p <0.04), the index of decay performance models (IF % 19.2 ± 9.4%; IF REAL 19.3 ± 10.9%;). The fourth [Lac] (6.1 ± 1.9 mM) was different from all other (p < 0.01). Only the flight time (F T ) to fifth effort (0.16 s ± 0.03) compared to the first and second (0.12 ± 0.01 s; 0.13 s ± 0.02; p < 0.05) showed differences. Thereby, the RAST offers stabilization performance and mechanical regardless of [Lac], so it can be a useful tool in the training process until the fourth effort. On study two, when tested correlations with performance, the best time 1.3.
