1. Operating Model and Estimation of the Insurance Premium for an Energy Futures Clearing House in Brazil
Abstract Purpose We propose and analyze a new operating model for an energy futures exchange that could be implemented in Brazil, where there is low liquidity for these contracts. The clearing house temporarily assumes the position of customers who fail to answer the margin call, instead of closing the position, as would normally be done under normal condit

3. DROP HEIGHT IS INFLUENCED BY BOX HEIGHT BUT NOT BY INDIVIDUAL STATURE DURING DROP JUMPS
RESUMO O desempenho do salto em profundidade (SP) é um aspecto importante em muitos esportes. A carga ideal de treinamento de SP é comumente prescrita através da altura da caixa da qual os indivíduos devem cair. No entanto, estudos relataram diferenças entre alturas de queda reais (calculadas) e alturas de caixas, o que pode afetar a qualidade da prescr

4. EFFECTS OF TRADITIONAL STRENGTH TRAINING AND OLYMPIC WEIGHTLIFTING IN HANDBALL PLAYERS
RESUMO Introdução O levantamento olímpico de halterofilismo tem sido adotado como alternativa ao exercício pliométrico. No entanto, pouco se conhece a respeito dos efeitos desses exercícios em jovens atletas de handebol. Objetivo Comparar o efeito do treinamento com levantamento olímpico e do treinamento de força tradicional no desempenho de salt

5. SOCCER CLEATS WITH BLADE-SHAPED STUDS AND MECHANICAL OVERLOAD IN SOCCER: A SYSTEMATIC REVIEW
RESUMO As chuteiras com travas em forma de lâmina promovem uma alta tração no gramado, podendo ser benéficas para o desempenho no futebol. Por outro lado, movimentos com rápidas mudanças de direção associados com tração alta das chuteiras podem aumentar a sobrecarga e as chances de lesão. Diante da falta de consenso sobre os efeitos dessas chuteir

6. Effects of linear and undulating periodization of strength training in the acceleration of skater children
Abstract Aim: This study aimed to compare the effects of linear periodization (LP) and undulating periodization (UP) of strength training on acceleration in skater children. Methods: Twenty-nine girls (9.67±1.29 years-old, 34.47±8.06kg, 1.39±0.13m) were distributed into two groups: linear periodization group (LPG, n=14) and undulating periodization grou

8. Description of training loads using whole-body exercise during high-intensity interval training
OBJECTIVES: To describe external training load and internal training load through sets of a single session of high-intensity interval training (HIIT) body work. METHODS: Twenty male individuals (24±3 years) performed a HIIT body work protocol consisting of a single bout of exercise with 1:1 stimuli. The exercises used were 30 min in duration with “all-o

9. Ruido magnético Barkhausen para el estudio de la anisotropía magnética en aceros inoxidables
ABSTRACT The magnetic Barkhausen noise (MBN) is a phenomenon that occurs in ferromagnetic materials when they are exposed to slowly varying magnetic fields, generating discrete jumps in their magnetization. These jumps are produced by the movement of the magnetic domain walls. They can be detected by a small coil allocated on the sample surface. The movement

10. Comportamiento magnético del acero AISI 304 en ensayos de tracción uniaxial
ABSTRACT During the magnetization process of a ferromagnetic material, the magnetic domain walls are forced to move due to the magnetic field influence. The domain walls must overcome the stress produced by the pinning sites (grain boundary, dislocations, inclusions, etc.), producing discrete jumps in the magnetization. These jumps can be detected with a sen

11. Grandes volumes são necessários para reduzir o desempenho muscular em indivíduos bem treinados
Resumo Um protocolo específico de Drop Jumps (DJs), com 100 saltos, tem sido amplamente utilizado para induzir o dano muscular. Entretanto, este protocolo tem falhado em mostrar uma queda relevante em indivíduos treinados. Objetivou-se avaliar o desempenho muscular após dois protocolos de DJs com diferentes volumes em indivíduos treinados. Dezoito homens

12. Biomechanical Parameters in Children with Unilateral and Bilateral Clubfoot during Vertical Jumps
Abstract Gait analysis may offer information to choose the best exercise-based clinical intervention for the children with clubfoot. However, other motor abilities are not commonly investigated. The aim of this research was to analyze the biomechanics of countermovement vertical jumping in clubfooted children who had undergone surgery. Fourteen children with
