O objetivo do presente estudo foi analisar o comportamento de 15 variáveis cinemáticas (tempo de passada, tempo de suporte, tempo de balanço, comprimento de passada, comprimento de passada relativo, freqüência de passada, ângulos do joelho e tornozelo no foot strike e no take-off, máxima flexão do tronco e máxima flexão do joelho na fase de suporte, amplitude angular do cotovelo durante a passada, máxima pronação da parte posterior do pé e amplitude vertical do centro de massa) e 8 variáveis neuromusculares (ativação elétrica muscular do reto femoral, vasto lateral, semitendinoso e bíceps femoral - porção curta – nas fases de suporte e balanço) da corrida, correlacionando-as com a economia de corrida (ECO). Dezesseis homens (idade: 27+1 anos; consumo máximo de oxigênio (VO2máx): 56,4+4,8 ml.kg-1.min), corredores fundistas com experiência em provas de 10.000 metros, realizaram um teste submáximo de corrida em esteira rolante na velocidade de 16 km.h-1 correspondente a uma intensidade média de 10,7% abaixo do limiar anaeróbio (LA) e a uma velocidade média de 11,1% abaixo da velocidade no LA. Foi utilizado um ergoespirômetro portátil para registro do consumo submáximo de oxigênio (VO2submáx) e para o registro das variáveis cinemáticas e neuromusculares da corrida, um sistema de captura de vídeo composto de duas filmadoras digitais de 120 Hz e um eletromiógrafo portátil de quatro canais com freqüência de amostragem de 2000 Hz por canal. O valor de ECO correspondeu à média do VO2submáx nos últimos dois minutos de teste, num total de seis minutos. A magnitude das variáveis cinemáticas e neuromusculares foram determinadas a partir da média de três ciclos de passada contabilizadas a partir da terceira passada do quarto minuto de teste. Foi feita a análise descritiva e aplicados os testes de Normalidade, Correlação Produto Momento de Pearson e Regressão Linear Múltipla. Verificaram-se relações diretas (+) e inversas (-) das variáveis cinemáticas (freqüência de passada (-28,3%), comprimento de passada (+23,0%), ângulo do joelho no foot strike (-12,7%), amplitude vertical do centro de massa (-7,2%), amplitude angular do cotovelo durante a passada (+5,6%), tempo de balanço (+3,2%), ângulo do tornozelo no foot strike (-0,6%) e comprimento de passada relativo (+0,4%)) com a ECO, totalizando 81%, e relações das variáveis neuromusculares (ativação elétrica muscular do semitendinoso na fase de suporte (+11,3%), do reto femoral (-4,3%) e do semitendinoso (+3,4%) na fase de balanço) com a ECO, totalizando 19%. Portanto, mudanças na técnica de corrida e na ativação elétrica muscular podem resultar em mudanças na ECO em corredores de 10.000 metros, que estejam se exercitando a uma intensidade próxima de 10% abaixo do LA. / The aim of the present study was to analyze the behavior of 15 kinematic variables (stride time, contact time, balance time, stride length, relative stride length, stride frequency, angles of the knee and ankle in foot strike and take-off, maximal flexion of the trunk and maximal flexion of the knee in the swing, angle excursion of the elbow, maximal pronation of the subtalar joint and vertical oscillation of the mass center) and 8 neuromuscular variables (electromyographic signal amplitude (EMG) of the vastus lateralis, biceps femoris, rectus femoris and semitendinosus muscles in the stance and swing) of distance running, correlating them with the running economy (ECO). Sixteen men (age: 27+1 years; maximal oxygen uptake (VO2max): 56,4+4,8 ml.kg-1.min), distance runners with experience in competitions of 10.000 meters, had carried through a test of the ECO (16 km.h-1) correspondent to an intensity mean of 10,7% below of the anaerobic threshold (LA) and 11,1% below of the velocity mean in the LA. Portable ergoespirometer for register of the submaximal oxygen uptake (VO2submáx) and for the register of the kinematic and neuromuscular variables of the distance runners was used one system of capture of the video with two high-speed camera (120 Hz) and an electromyography portable of four canals with 2000 Hz for canal. The value of ECO correspond the average of the VO2submax in last the two minutes of test, in a total of six minutes. The magnitude of the kinematic and neuromuscular variable passing had been determined from the average of three cycles of stride. The tests of “Normality”, “Pearson correlation” and “Multiple Linear Regression” were performed. Direct relations (+) and inverse (-) of the kinematic variables (stride frequency (-28,3%), stride length (+23,0%), angle of the knee in foot strike (-12,7%), vertical oscillation of the mass center (-7,2%), wrist excursion (+5,6%), balance time (+3,3%), angle of the ankle in foot strike (-0,6%) and relative stride length (0,4%)) with the ECO, totalizing 81%, and relations of the neuromuscular variables (EMG of the semitendinosus in the stance (+11,3%), of the rectus femoris (-4,3%) and of the semitendinosus (+3,4%) in the swing) had been verified with ECO, totalizing 19%. Therefore, changes in the technique and the EMG can result in changes in the ECO in distance runners with experience in competitions of 10.000 meters, in intensities next to 10% below of the LA.

Title: Evaluation of running techniques in elite Czech male and female runners Aims: The main goal of the work is to evaluate the running technique of elite Czech male and female runners on middle tracks and intra-individual variability of the running style. Methods of work: Qualitative kinematic analysis of motion and quantitative cinematographic examination method of video recording of running technique were used to create this work. The records were further processed using Adobe Photoshop, Adobe Premiere, Kinovea and Microsoft Excel. Results: The individual probands of the research group fulfill a substantial part of the model running technique recommended by the literature such as the active forefoot strike, the duration of individual phases, or the correct position of the head, torso, and extended reflex limb in the propulsion phase. So, we can say that Czech runners are technically capable. However, at the same time we observe a different individual concept of running technique for each proband, such as lumbar hyperlordosis, retroflection of torso, head tilt or the extent of arm work. Key words: biomechanics of motion, kinematic analysis, running technique, economics of motion

Background: Lately, barefoot running has become popular and there is a debate on the pros and cons of barefoot running with regards to running injuries. Many factors are causing injuries and one of the factors discussed is the fact that we run in shoes. When we run in shoes the biomechanics of the running technique may and therefore be a possible cause to injury. Aim: The aim of the study was to assess how the foot strike pattern, angle of the knee and ankle joint at time of initial contact, as well as the step length changes between a shod and barefoot running condition in habitually shod runners when running in a pace equivalent to their running pace over ten kilometers. Method: Twenty-seven healthy runners (18 male, 9 female) were included in the study. The study took place at the fitness center of Halmstad University. Subjects ran on a treadmill, in an individual pace equivalent to their running pace over ten km, both in a shod and barefoot running condition. Two-dimensional analysis of the sagittal plane kinematics of the knee joint, ankle joint and foot position to horizontal, foot strike pattern and step length was done. Participants ran for ten minutes with shoes and for five minutes barefoot. Running technique was videotaped using an Iphone 6 camera and landmarks were marked with white tape to ease the analysis. Results: Changes in foot strike pattern was observed. When running barefoot 63% of the subjects adopted a non-heel strike pattern compared to 18.5% when shod (p=0.001). Knee flexion was increased at IC for the barefoot condition, with 164°±6 relative knee angle compared to 167°±6 when shod (p=0.001). Ankle angle at IC did not show a statistical significant difference between conditions (p=0.657). When barefoot the angle was 117°±8 compared to 115°±8 when shod. Foot angle to horizontal showed a flatter foot placement at IC with a less dorsiflexed foot for the barefoot condition (-4°±8) compared to shod (-12°±8), (p=0.001). Step length was decreased for the barefoot condition (0.82m ±0.15)   compared to shod (0.85m ±0.13), (p=0.008). Conclusion: Results are consistent with previous findings that barefoot running in some cases change the running technique with a flatter foot placement, an increased knee flexion at IC and a decreased step length. However, caution must be taken when habitually shod runners transition to barefoot running in regards to the biomechanical changes that may occur. To benefit from barefoot running a non-heel strike pattern is required. Further, the running technique may be the more important factor, regardless of wearing shoes or not.

Com o objetivo de comparar os efeitos do treinamento de força rápida em parâmetros fisiológicos, mecânicos e neuromusculares de corredores de fundo, o presente trabalho contou com uma amostra de 18 atletas amadores do sexo masculino, praticantes de corrida de rua e com experiência em provas de longa distância (21km ou acima). A amostra foi selecionada para o grupo \"treinamento de força rápida\", (RPG - grupo experimental) ou \"exercícios educativos técnicos de corrida\" (RTG - grupo controle), que realizaram seis semanas de exercícios distintos. No intuito de avaliar o desempenho em variáveis-chave para o rendimento de fundistas, os sujeitos foram submetidos a uma série de testes em dois momentos distintos: após a semana de aprendizagem e adaptação aos exercícios (pré) e ao final das seis semanas dos protocolos propostos (pós). A bateria de testes foi composta por: testes de saltos verticais (Altura [H], Potência Pico [PP] e Potência Relativa [PR] do salto para as técnicas Squat Jump [SJ], Counter Movement Jump [CMJ] e Drop Jump 40cm [DJ40]); salto horizontal [SH] e salto sêxtuplo alternado [S6A] (distância saltada); uma repetição máxima no agachamento guiado (carga absoluta [1RM Abs.] e relativa à massa corporal [1RM Rel.]); teste de contração isométrica voluntária máxima (CIVM - força pico [Fpico], força pico relativa à massa corporal [Fpico R.], tempo da força pico [TFPICO] e taxa de desenvolvimento de força [TDF]); teste incremental de esteira (Velocidade Pico em Esteira [VPE] e Velocidade do Limiar de Lactato [vLL]); e tempo limite em esteira na VPE (Tlim). O tratamento estatístico foi realizado por meio do Software IBM® SPSS® Statistics v. 20.0, para Windows (IBM Corporation, Chicago, USA). A ANOVA Modelo Misto foi utilizada para as comparações das variáveis de desempenho entre momentos e entre grupos, com teste post-hoc de Bonferroni quando necessário, e o teste t de Student para amostras independentes foi realizado para comparar as variáveis relativas ao treinamento entre os grupos. Todas as variáveis foram submetidas aos testes estatísticos Cohen\'s \"d\" de Magnitude de Efeito (ES) e Probabilidade Quantitativa de Chances (QC). Foram encontradas diferenças estatisticamente significantes para as variáveis Altura de Salto e Potência Relativa para a técnica de salto vertical Squat Jump entre os momentos pré e pós treinamento para o grupo RPG (HSJ: F = 6,973; p = 0,018; PRSJ: F = 8,421; p = 0,01) e Altura de Salto e Potência Relativa para a técnica de salto vertical Counter Movement Jump entre os grupos RPG e RTG, após as seis semanas de exercícios (HCMJ: F = 6,163; p = 0,025; PRCMJ: F = 4,667; p = 0,046). Foi identificada diferença significativa para a variável \'tempo da Fpico\' (F = 7,731; p = 0,013) durante o teste de CIVM para o grupo RPG entre os momentos. O grupo Controle, ainda, apresentou queda na variável VPE após as seis semanas do protocolo (F = 5,493; p = 0,032), o que não foi observado no grupo Pliometria. Ademais, o grupo experimental apresentou redução nos valores de lactato sanguíneo nos minutos 1, 3 e 5 após o teste de Tlim (F = 16,858; p = 0,001; F = 8,406; p = 0,01; F = 12,092; p = 0,003, respectivamente). É possível concluir que o treinamento pliométrico foi superior ao protocolo de exercícios educativos no intuito de melhorar o desempenho da força rápida de membros inferiores, contribuindo, ainda, para a manutenção dos níveis iniciais de desempenho em corrida e a melhora da remoção do lactato sanguíneo, o que não pode ser observado no grupo RTG. / With the purpose to compare the effects of explosive-strength training in physiologic and neuromuscular variables of endurance runners, the present study accounted with 18 male amateur athletes experienced in long distance races (21km and above). The sample was divided between explosive-strength training - RPG (running plyometrics group) and technique exercises protocol - RTG (running techniques group), which performed six weeks of distinct exercise protocols. With the aim to evaluate key-variables for endurance running performance the subjects were submitted to batteries of assessments in two different moments: after the exercises adaptation week and right before the beginning of the protocols, and at the end of the exercise protocols. The assessments battery contained vertical jump tests (Jump Height [H], Peak Power [PP] and Relative Power [RP] for the techniques Squat Jump [SJ], Counter Movement Jump [CMJ] and Drop Jump 40cm [DJ40])/ horizontal long jump (SH) and sextuple jump alternating legs (S6A), one maximum repetition for squat at Smith Machine (absolute [1RM Abs.] and relative to body mass loads [1RM Rel.]), maximum voluntary isometric contraction test (MVIC - peak force [Fpico], peak force relative to body mass [Fpico R.], time to peak force [TFPICO] and rate of force development [TDF]); maximum incremental treadmill test (treadmill peak velocity [VPE] and lactate threshold velocity [vLL]), and time limit test at treadmill peak velocity (Tlim). The statistical procedures were performed at IBM® SPSS® Statistics Software v. 20.0, para Windows (IBM Corporation, Chicago, USA) The Mixed Model ANOVA was performed with dependent variables to identify time and group interactions, using the Bonferroni post-hoc test when necessary, while the training variables were analyzed by the Student\'s t test for independent samples. All data were also analyzed with Cohen\'s \"d\" Effect Size test (ES) and Probability of Quantitative Chances (QC). There were found in RPG significant differences for H and PR for Squat Jump technique between moments pre- and post-protocol (HSJ: F = 6,973; p = 0,018; PRSJ: F = 8,421; p = 0,01), and for the same variables for Counter Movement Jump technique between RPG and RTG (HCMJ: F = 6,163; p = 0,025; PRCMJ: F = 4,667; p = 0,046) after the exercise protocols. Also, significant difference was found for \'time to peak force\' variable (F = 7,731; p = 0,013) during the MVIC test for the group RPG between moments. Yet, the control group presented significant decrease of peak treadmill velocity in the moment post- compared to the pre-training (F = 5,493; p = 0,032), which was not observed in the experimental group. Still, the experimental group presented lower values for lactate concentrations 1, 3 and 5 minutes after Tlim test (F = 16,858; p = 0,001; F = 8,406; p = 0,01; F = 12,092; p = 0,003, respectively). It is possible to conclude that the plyometric training performed by the RPG was superior to the technique exercises protocol in the objective of increasing lower-limbs explosive-strength parameters, contributing to the maintenance of running performance and a better lactate clearance capacity, which did not happen in the RTG.
