Simple Summary In the last decades, performance models have helped to comprehend the mechanisms involved in long-term physical performance. In addition, predictive models have aided in the evaluation and prescription of physical training. Here, we tested the hypothesis that physiological assessments under inclined conditions would better explain hi...

The objective of this study was to evaluate the effects of a training session with and without an intervention of postactivation performance enhancement (PAPE) on countermovement jump (CMJ) height, perceived recovery status (PRS), and ratings of perceived exertion (RPEs), followed by a specific volleyball training session. The sample consisted of s...

A doença de Parkinson (DP) apresenta prejuízo no equilíbrio e piora de sintomas motores, os quais podem aumentar o risco de quedas. O exercício físico tem se mostrado uma estratégia eficaz para combater os sintomas e o avanço da DP. A caminhada parece ser uma das estratégias mais utilizadas dentro da reabilitação na DP. Além disso, a caminhada real...

Purpose: The authors aimed to compare the effects of 4 weeks jump versus complex training methods on lower limb muscle power and maximal isokinetic torque of knee extensors and flexors in elite male volleyball players. Methods: Sixteen male volleyball players were allocated into 2 groups, jump training (n = 8; 27.0 [5.7] y, 94.3 [7.6] kg) and co...

The main objective of this study is to propose a form of walking/running protocol that is capable of evaluating energy expenditure at different types of slopes, considering the same relative intensities (iso-intensity conditions), as well as to assess biomechanical and hemodynamic factors that may be associated. 11 obese adult men (BMI between 30 k...

The objective of this study was to evaluate effects of photobiomodulation therapy (PBMT) on the 3000 m running performance (primary outcome), running economy (RE), metabolic cost and ratings of perceived exertion during running (secondary outcomes). Twenty male endurance athletes performed 4-min treadmill rectangular test at 12 km.h-1 monitored by...

O livro é um enfrentamento e uma reflexão crítica sobre diferentes marcadores sociais estruturantes da nossa vida social (racismo, gênero, classe social, educação e saúde, esporte e lazer, entre outros). A obra se constitui de duas partes: na primeira, quatro personalidades que transcendem suas especificidades disciplinares, com reconhecimento naci...

New findings: What is the central question of this study? The aim was to compare the cost of transport and mechanical work between obese and non-obese children at different walking speeds. What is the main finding and its importance? Our data show that the cost of transport, mechanical efficiency and work are similar and directly mass dependent in...

Endurance running has become an immensely popular sporting activity, with millions of recreational runners around the world. Despite the great popularity of endurance running as a recreational activity during leisure time, there is no consensus on the best practice for recreational runners to effectively train to reach their individual objectives a...

Background: Nordic walking is an attractive method of endurance training. Nevertheless, the biomechanic response due to the additional contribution of using poles in relation to free walking training has been less explored in the elderly. Purpose: This randomized parallel controlled trial aimed to assess the effects of 8 weeks of Nordic walking...

Although cycling impairs the subsequent metabolic cost and performance of running in some triathletes, the consequences on mechanical efficiency (Eff) and kinetic and potential energy fluctuations of the body center of mass are still unknown. The aim of this study was to investigate the effects of previous cycling on the cost-of-transport, Eff, mec...

Background: Elastic bouncing is a physio-mechanical model that can elucidate running behavior in different situations, including landing and takeoff patterns and the characteristics of the muscle-tendon units during stretch and recoil in running. An increase in running speed improves the body’s elastic mechanisms. Although some measures of elastic...

Nordic walking has been shown as an attractive method of aerobic training. Nevertheless, the biomechanical response due to the additional contribution of using poles in relation to free walking training has been less explored in the elderly. This randomized parallel controlled trial aimed to assess the effects of eight-weeks of Nordic walking and f...

Background: Individuals with visual impairment (VI) have often been observed to walk slower than individuals with unimpaired vision. These observations might be confounded by typical low levels of physical activity and greater sedentary behavior in individuals with VI than the overall population. Research question: Here, we compared gait and bal...

Aerobic training has a neuroprotective effect in people with Parkinson’s disease. Recent evidence indicates that Nordic walking seems a promising alternative due to positive outcomes in functional mobility. However, the effects of Nordic walking compared to free walking on static and functional balance parameters are still unknown. The aim of this...

Knee peak torque (PT) is associated to jump performance in volleyball players. It is not clear whether muscle strength imbalances of the knee joint can influence jump performance. The purpose of study was to analyse the association between PT and knee muscular imbalances with jump performance in professional volleyball players. Eleven elite male vo...

Jump tests and isokinetic dynamometer assessments are widely used in sports to identify parameters of strength and power development. Understanding the relationship between these variables can help in the selection of more specific parameters to assess the strength of knee joint muscles on isokinetic dynamometer in volleyball players. The objective...

O triatlo caracteriza-se por ser um esporte múltiplo composto por três modalidades: natação, ciclismo e corrida que ocorrem nessa ordem e em sequência. Na etapa da corrida, o atleta sofre efeitos decorrentes das modalidades que a antecederam (natação e ciclismo) podendo assim, alterar parâmetros biomecânicos e fisiológicos da corrida. Objetivo: o o...

The purpose of this study was to evaluate the midfoot longitudinal arch height and correlate it with active hip external rotation (ER) in dancers during static postures and technical steps of classical ballet (i.e., first position, demi-plié, battement fondu à la seconde, pas jeté à la seconde, and grand jeté à la seconde). A 3D motion analysis sys...

Although studied at level surface, the trunk kinematics and pelvis-shoulder coordination of incline walking are unknown. The aim of this study was to evaluate the speed effects on pelvis-shoulder coordination and trunk movement and the cost of transport (C) during unloaded and loaded (25% of body mass) 15% incline walking. We collected 3-dimensiona...

The dynamic stability (DE) is an important indicator of the quality of life, because it indicates lower balance during walking and is related to the fall risk. The walk stability is a critical issue for stroke individuals. The aim of this study was to compare the DE of walking at different speeds in healthy and stroke patients. The study included s...

It has been observed that the optimal speed (OPT) of human walking is independent of load on level surfaces because of the unaltered trajectory of the center of mass and consequent conservation of the pendular mechanism. However, the role of the inverted pendulum mechanism that combines speed, load, and gradient during walking remains unknown. In t...
