3. Ischemic preconditioning delays the time of exhaustion in cycling performance during the early but not in the late phase
Abstract Aims: To investigate the early and late ischemic preconditioning (IPC) effect on the trained cyclists’ performance during incremental cycling test until exhaustion. Methods: Twenty-one male cyclists allocated to an IPC (2 x 5-min of blood flow occlusion at 50 mm Hg above systolic pressure followed + 5-min of deflation), SHAM (2 x 5-min at 20 m

6. Can power and anaerobic capacity reduce according to disordered eating behaviors in cyclists?
Abstract The present study aimed to compare the power, anaerobic capacity (AC) and performance in a road bicycle race among cyclists with and without risk of disordered eating behaviors (DEB). The sample was selected in a non-probabilistic way, totaling 69 male road cyclists aged between 19 and 30 years. The Wingate test was used to evaluate peak power (PP)

7. Electromyographic analysis of riding posture during the bicycling start moment
Abstract Professional cyclists often adopt a competition-start standing posture, which has been shown to improve performance. The biomechanical basis of this is unclear, and might be due to a greater mechanical advantage or increased key muscle activity. Previous observations in steady state cycling showed greater activation of the tibialis anterior, erector

9. Measurement and evaluation of human exposure to vibration transmitted to hand-arm system during leisure cyclist activity
INTRODUCTION: The cycling activity has increased in recent years, either as a means of leisure or physical activity or as means of transport. Discomfort is one of the main complaints for cyclists, especially when related to the type o pavement they use while riding. This work presents a study of measurement and evaluation of human exposure to hand-arm vibrat

10. Effect of β-alanine supplementation on 20 km cycling time trial performance
The effects of β-alanine supplementation on high-intensity cycling performance and capacity have been evaluated, although the effects on longer duration cycling performance are unclear. Nineteen UK category 1 male cyclists completed four 20 km cycling time trials, two before and two after supplementation with either 6.4 g•d-1 β-alanine (n = 10; BA) or a

11. Efeitos da ingestão de cafeína sobre o desenvolvimento físico de ciclistas em prova contra-relógio de 1 km
O propósito deste estudo foi analisar os efeitos da ingestão de cafeína (CAF) sobre o desempenho físico em exercício fechado de curta duração. Dez ciclistas (participavam de competições nacionais, estaduais e regionais) do sexo masculino (27 ± 8 anos, 71 ± 10,3 kg, 173 ± 6,5 cm, 345 ± 92 km.sem-1) completaram inicialmente um teste incremental m�

12. Influência de diferentes estratégias de prova na recuperação fisiológica e no desempenho de ciclistas treinados / Influency of the pacing strategy on the physiologic recovery and performance of trained cyclists
Esforços físicos prolongados em ritmo dinâmico parecem promover menor demanda metabólica, estresse fisiológico e cardiovascular comparado a tarefas em ritmo constante. Contudo, os mecanismos não são completamente descritos. Além disso, sugere-se que o tempo que o indivíduo é capaz de suportar um exercício em intensidade máxima (TLim[FCmax]) corre
