The aims of this study were to compare Brazilian Jiu-Jitsu (BJJ) experienced practitioners (EX) with beginners (IN) in relation to isometric and dynamic endurance strength, isometric maximal strength and maximal aerobic power (VO2max) and to examine correlations between tests as well. Twenty-eight BJJ practitioners were selected and divided into two groups: EX (N = 14, 33.8 ± 5.6 years; purple to Black belt, 6....
— Aims: To analyze if different resistance training (machine vs free weight) would have different acute hypotensive effect in active and normotensive individuals. Methods: Fifteen male volunteers (39.2±2.5 years) performed two different resistance exercise protocols, one on machinery and one with free weights for the similar muscle groups and volume (sets x repetitions). Systolic blood pressure (SBP) and diasto...
The Olympic weightlift (OW) is one of the oldest sports of the Olympic Games of the modern era. Furthermore, for a long time it is widespread its use as performance improves so in various sports. Regarding the international literature, one can find large number of publications about the topic, however, at the national level is still scarce studies with OW. Additionally, among many professional health area as ph...
The isometric strength endurance (ISE) of upper limbs is important for the performance in Brazilian Jiu-Jitsu (BJJ). Contraditory results are reported in the literature about their behavior after BJJ match. Thus, the aim of this study was to investigate this response through the maximum static lift (MSL) using the kimono lapel grip holding around the bar in BJJ athletes after one simulated match. Materials and ...

We evaluated the effect of performing various distinct warm-up exercises on vertical countermovement jump (VCMJ) performance. Eight volleyball players (age 15.4 ± 0.5 yrs) performed five different warm-up activities (in a counterbalanced, randomized crossover study) over five days, at 24-h intervals: stretching (4 × 30 s, 30 s between sets), cycloergometer (5 min at 50 W + 5 min at 100 W), resistance exercise (...
Objective: To determine through of a systematic review the key components related to physiological and physical performance in athletes wheelchair rugby. Method: For the search, we used the descriptors "Wheelchair" and "Rugby" isolated and / or combined. We analyzed the studies originally published in English between January 2004 to December 2012, in databases PubMed, Scopus and Web of Science. Results: Initial...
Objective: To review the scientific research regarding collective sports modalities for people with disabilities and to suggest directions for future studies. Methods: Studies were identified from a systematic search of three databases. The research was limited to the english and portugueselanguages, and published up to January 2018. The papers were summarized and analyzed in relation to absolute and relative f...
Objective: To present nutritional ergogenic aids investigated by scientific research involving rugby players and their performance in trainings and matches. Methods: A systematic review was carried out through Pubmed database in January 2013 with the following key-words: rugby, supplementation, carbohydrate, protein, amino acid and caffeine isolated and/or combined. In the analyses, only original studies publis...
The aim of this study was to investigate the neuromuscular performance responses following successive Brazilian Jiu-Jitsu (BJJ) fights. Twenty-three BJJ athletes (age: 26.3 ± 6.3 years; body mass: 79.4 ± 9.7 kg; body height: 1.80 ± 0.1 m) undertook 3 simulated BJJ fights (10 min duration each separated by 15 min of rest). Neuromuscular performance was measured by the bench press throw (BPT) and vertical counter...
