25. Identification and agreement of first turn point by mathematical analysis applied to heart rate, carbon dioxide output and electromyography
BACKGROUND: The second heart rate (HR) turn point has been extensively studied, however there are few studies determining the first HR turn point. Also, the use of mathematical and statistical models for determining changes in dynamic characteristics of physiological variables during an incremental cardiopulmonary test has been suggested. OBJECTIVES: To

26. Variabilidade da frequência cardíaca após treinamento concorrente : comparação entre homens e mulheres de meia-idade = Heart rate variability after concurrent training : comparison between middle-aged men and women / Heart rate variability after concurrent training : comparison between middle-aged men and women
The autonomic nervous system dysfunction and the increase in chronic degenerative diseases are manifested by the aging process, leading to changes of the autonomic modulation cardiac, and therefore the heart rate variability. Regarding the response of the autonomic nervous system and cardiorespiratory adaptive responses are even less enlightening evidencing

27. Modulação do metabolismo muscular em camundongos exercitados e suplementados com leucina / Modulation of muscle metabolism by exercise and leucine supplementation in mice
We investigated the effects of chronic physical training, associated or not with leucine supplementation, on protein and glucose metabolism in soleus muscle of Swiss mice. Half of the mice (T) performed a 12 weeks protocol of swimming exercise, 1h/day, 5 days/week, bearing no overload, and the other half remained sedentary (C). Additionally, half of the C an

31. Influence of previous experience on the preference, food utilization and performance of Ascia monuste orseis wild larvae (Godart) (Lepidoptera: Pieridae) for three different hosts
The exhaustion of food resources which occurs during the ontogenetic growth of Ascia monuste orseis (Godart) results in the dispersion of older larvae to nearby plants in order to complete their development, which might expose these animals to the nutritional variation of the hosts found. This study aimed to verify whether the food ingested in the beginning

34. Velocidade da marcha como preditor de fragilidade em uma amostra populacional de idosos brasileiros
Gait speed has been described as a predictive indicator of important adverse outcomes in older populations. Among the criteria to evaluate frailty, gait speed has been identified as the most reliable predictor of fragility, practical and low cost. Objective: This study assesses the discriminating capability of gait speed in determining the presence of fragil
