Moderate intensity and volume downhill run does not impair knee joint stability...
Assumpção, Cláudio de Oliveira; Lima, Leonardo Coelho Rabello de; Oliveira, Felipe Bruno Dias de; Greco, Camila Coelho; Denadai, Benedito SérgioBACKGROUND AND OBJECTIVE: Muscle strength imbalance can be an important factor in hamstrings muscle strain. The main purpose of this study was to investigate the effects of downhill running on hamstrings/quadriceps torque (H/Qtorque) and the electromechanical delay (H/QEMD) ratios. METHODS: Fifteen active male individuals performed two maximal voluntary isometric contractions of the knee extensors and knee flex...
A single bout of downhill running attenuates subsequent level running-induced f...
Assumpção, Claudio de Oliveira; Barreto, RenanVieira; Lima, Leonardo Coelho Rabello de; Cardozo, Adalgiso Coscrato; Montebelo, Maria Imaculada de LimaFatigue can be defned as exercise-induced strength loss. During running, fatigue can be partially explained by repetitive low-intensity eccentric contractions-induced muscle damage (EIMD). Previous studies showed that a bout of downhill running (DR) attenuated subsequent EIMD. Thus, we tested if a 30-min DR bout would attenuate fatigue induced by subsequent 60-min level running (LR). Twentyseven male college st...
Efeitos da caminhada em declive na aptidão aeróbia e neuromuscular em adultos j...
Lima, Leonardo Coelho Rabello de; Oliveira, Thiago Pires de; Oliveira, Felipe Bruno Dias de; Santos, Fernanda FioravantiAzank dosEccentric exercise training using low intensity-high volume approach has been performed to improve maximal muscle strength and power. The aim of this study was to compare the effects of short-term downhill walking and level walking training on lower limb strength and maximal oxygen uptake of active individuals. Eighteen young adults were divided into level walking group (n = 9) or downhill walking training grou...
Postactivation Potentiation Biases Maximal Isometric Strength Assessment
Lima, Leonardo Coelho Rabello; Oliveira, Felipe Bruno Dias; Oliveira, Thiago Pires; Assumpção, Claudio de Oliveira; Greco, Camila CoelhoPostactivation potentiation (PAP) is known to enhance force production. Maximal isometric strength assessment protocols usually consist of two or more maximal voluntary isometric contractions (MVCs). The objective of this study was to determine if PAP would influence isometric strength assessment. Healthy male volunteers ( = 23) performed two five-second MVCs separated by a 180-seconds interval. Changes in isom...
Exercise-Induced Muscle Damage and Running Economy in Humans
Assumpção, Claudio de Oliveira; Lima, Leonardo Coelho Rabello; Oliveira, Oliveira; Greco, Camila Coelho; Denadai, Benedito SérgioRunning economy (RE), defined as the energy demand for a given velocity of submaximal running, has been identified as a critical factor of overall distance running performance. Plyometric and resistance trainings, performed during a relatively short period of time (∼15–30 days), have been successfully used to improve RE in trained athletes. However, these exercise types, particularly when they are unaccustomed ...
Monitoramento de marcadores de dano muscular durante um programa de quatro sema...
Lima, Leonardo Coelho Rabello de; Oliveira, Thiago Pires de; Oliveira, Felipe Bruno Dias de; Assumpção, Claudio de Oliveira; Greco, Camila CoelhoEccentric-based exercise is known to induce muscle damage (MD). The purpose of this study was to investigate effect of downhill walking (DW) sessions on MD and aerobic markers in young adults. Eight male subjects were submitted to a 4-week DW periodized exercise program. Subjects' soreness (SOR) was assessed each training day. Serum creatine quinase activity (CK) was collected before the first training session,...

Caritá, Renato Aparecido Corrêa; Picarelli, Cintia; Greco, Camila Coelho; Denadai, Benedito SérgioO objetivo deste estudo foi analisar o efeito do exercício prévio severo (EPS) sobre a potência crítica (PC) e a capacidade de trabalho anaeróbio (CTA) determinados durante o exercício de ciclismo. Sete indivíduos realizaram os seguintes protocolos em cicloergômetro: (a) teste progressivo para determinação do limiar ventilatório (LV), consumo máximo de oxigênio (VO2max) e sua respetiva intensidade (IVO2max); (b...
