1. What pacing strategy 800m and 1500m swimmers use?
Resumo A estratégia de prova (EP) tem impacto determinante no desempenho esportivo, principalmente em provas de longa duração. O objetivo foi caracterizar a EP utilizada em provas de natação de 800m e 1500m livre por finalistas das seletivas olímpicas dos Estados Unidos, Europa, Brasil e finalistas olímpicos de 2016. As parciais de tempo de 63 atletas

2. Stress-reducing and anesthetic effects of the essential oils of Aloysia triphylla and Lippia alba on Serrasalmus eigenmanni (Characiformes: Serrasalmidae)
RESUMO Avaliou-se o efeito anestésico dos óleos essenciais de Aloysia triphylla e de Lippia alba no peixe amazônico Serrasalmus eigenmanni. Os peixes foram colocados em aquários contendo OEs de A. triphylla ou L. alba (25 a 200 µL L-1). Após, foram transferidos para aquários com água sem anestésicos para avaliar o tempo de recuperação. Em outro ex

3. Reproductive biology of the Brazilian blind electric ray Benthobatis kreffti (Chondrichthyes: Narcinidae)
RESUMO Este estudo apresenta informações sobre a biologia reprodutiva da raia elétrica cega brasileira Benthobatis kreffti, endêmica do sul e sudeste brasileiros. Os indivíduos foram capturados com arrasto de fundo, em 2003 e 2007, a 492-501 m de profundidade no talude continental do Estado de São Paulo. Um total de 152 fêmeas (115-299 mm) e 144 macho

4. Effects of taurine supplementation in elite swimmers performance
Abstract AIM Taurine is considered a semi-essential amino acid characterized by having various physiological functions in the body that modulate mechanisms of action involved in the muscle contraction process, increased energy expenditure, insulin signaling pathway, carbohydrate metabolism, and scavenging free radicals. These functions are crucial for aerob

5. Effects of the platelet-rich fibrin associated with physical exercise in a model of median nerve compression.
Abstract AIMS Platelet-Rich Fibrin (PRF) is a new and promising technique for tissue repair, however, there is still a gap about its action on peripheral nerve injury, as well as its association with physical exercise. Thus, the aim of this study was to evaluate the effects of the PRF associated with physical exercise in a model of median nerve compression.

6. Sustained swimming improves fish dietary nutrient assimilation efficiency and body composition of juvenile Brycon amazonicus
ABSTRACT Sustained swimming (SS) usually promotes beneficial effects in growth and feed conversion of fishes. Although feed efficiency is improves at moderate water velocity, more information is required to determine the contributions of this factor on growth and body composition. Body composition and efficiency responses to the use of nutrients were determi

7. Exercise improved lipid metabolism and insulin sensitivity in rats fed a high-fat diet by regulating glucose transporter 4 (GLUT4) and musclin expression
This study aimed to evaluate the effects of exercise training on triglyceride deposition and the expression of musclin and glucose transporter 4 (GLUT4) in a rat model of insulin resistance. Thirty male Sprague-Dawley rats (8 weeks old, weight 160±10 g) were fed a high-fat diet (40% calories from fat) and randomly divided into high-fat control group and swi

8. Effects of immobilization and remobilization on the ankle joint in Wistar rats
A sprained ankle is a common musculoskeletal sports injury and it is often treated by immobilization of the joint. Despite the beneficial effects of this therapeutic measure, the high prevalence of residual symptoms affects the quality of life, and remobilization of the joint can reverse this situation. The aim of this study was to analyze the effects of imm

9. Tadpoles of the High-Andean Hyloxalus subpunctatus (Anura: Dendrobatidae) with description of larval variation and species distinction by larval morphology
This study redescribes the tadpoles of Hyloxalus subpunctatus (Anura: Dendrobatidae) based on larvae from the type locality and over most of its geographic range, including all stages of ontogenetic development. I describe tadpoles in the three developmental phases: (1) back-riding tadpoles, (2) free-swimming tadpoles, (3) froglets or individuals in metamorp

10. A new look into the small-scale dispersal of free-living marine nematodes
We tested experimentally the hypothesis that prevailing locomotion/feeding strategies and body morphology may lead to more active dispersal of free-living marine nematodes, besides passive transport. Neutral Red was applied to the sediment inside cores and the red plume formed during the flood tide was divided into near, middle, and distant zones. At 0.5 m a

11. Concentração de triptofano e variáveis cinemáticas a diferentes percentuais da velocidade crítica no nado crawl
The aim of this study was to investigate the changes in plasma tryptophan concentration ([TRP]) and kinematic variables in a series of interval training in different percentages of the critical speed (CS) in front crawl. Volunteers were 14 competitive male swimmers with at least four years experience in this style and swimming 48 ± 11 km per week. The subje

12. Participação das vias de estresse oxidativo na neuroproteção mediada pelo treinamento físico em fatias cerebrais submetidas à privação de oxigênio e glicose
Ischemia leads to a variety of pathological events, including excitotoxicity, inflammation, delayed neuronal dysfunction and cell death through hyperactivation of glutamate receptors and production of free radicals, such as nitric oxide (NO). The mechanism by which cerebral excess formation of NO, which mediates neuronal death involving energy depletion, lip
