37. Factors associated with body image dissatisfaction of weight training practitioners
Abstract AIMS This study aimed at investigating the socio-demographic and health-related variables associated with body image dissatisfaction. METHODS This is a cross-sectional study. 894 (34.04±13.62 years old) weight training practitioners from a medium-large city in the south of Brazil participated in this study. A socio-demographic questionnaire was u

38. The acute hypotensive effect of resistance training performed with machines vs free weights in normotensive men
Abstract AIMS To analyze if different resistance training (machine vs free weight) would have different acute hypotensive effect in active and normotensive individuals. METHODS Fifteen male volunteers (39.2±2.5 years) performed two different resistance exercise protocols, one on machinery and one with free weights for the similar muscle groups and volume

39. Effects of Conventional and Virtual Reality Cardiovascular Rehabilitation in Body Composition and Functional Capacity of Patients with Heart Diseases: Randomized Clinical Trial
Abstract Background: Virtual reality is an alternative therapeutic resource to be inserted into cardiovascular rehabilitation, stimulating the practice of physical activity through man-machine interaction. Objective: To compare the effects of conventional and virtual reality cardiac rehabilitation on body composition and functional capacity in patients wit

40. Comparison of endoplasmic reticulum stress and mitochondrial biogenesis responses after 12 weeks of treadmill running and ladder climbing exercises in the cardiac muscle of middle-aged obese rats
The purpose of the present study was to compare the influence of aerobic exercise (AE) lasting 12 weeks to that of resistance exercise (RE) of the same duration on endoplasmic reticulum (ER) stress and mitochondrial biogenesis in the cardiac muscle of middle-aged obese rats. Obesity was induced in thirty 50-week-old male Sprague Dawley rats over 6 weeks by a

41. Protective Effects of Accumulated Aerobic Exercise in Infarcted Old Rats
Abstract Background: Aerobic exercise exerts cardioprotective effects on myocardial infarction. However, there is lack of information about the possible protective effects of continuous or accumulated aerobic exercise performed prior to myocardial infarction in aging. Objective: To evaluate the preventive effects of continuous or accumulated aerobic exerci

42. Drinking to thirst influences fluid replacement in adolescents judokas
Abstract AIM The aim of this study was to examine the influence of the type of beverage and the use of thirst sensation to guide fluid replacement in the adolescent judokas. METHODS Nine male judokas aged 10-16 (average age 11,8 ± 4,0 years old) were submitted to a standardized training of 90 minutes. In the first phase of the study, the athletes complete

43. Monitoring training load in beach volleyball players: a case study with an Olympic team
Abstract AIM Describe and compare training load dynamics of two Olympic beach volleyball players. METHODS Two Olympic beach volleyball players participated in this study (specialist defender and blocker: both aged 34 years, holding 14 years of competitive experience, height: 1.74 m and 1.81 m, weight: 69 kg and 65 kg, respectively). Internal training load

44. COMPARISON OF RESPONSE SURFACE METHODOLOGY (RSM) AND ARTIFICIAL NEURAL NETWORKS (ANN) TOWARDS EFFICIENT OPTIMIZATION OF FLEXURAL PROPERTIES OF GYPSUM-BONDED FIBERBOARDS
ABSTRACT In this study, the hydration behavior of gypsum paste mixed with bagasse and kenaf fibers as lignocellulosic material and fiberglass as inorganic material is evaluated. Moreover, the properties of gypsum-bonded fiberboard (GBFB) are examined using bagasse fibers (Saccharum officinarum.L), kenaf fibers (Hibiscus cannabinus.L) and industrial fiberglas

45. Individual and average responses of sleep quality and daytime sleepiness after four weeks of strength training in adolescents
Abstract Aims: To analyze the average and individual responses of sleep quality and daytime sleepiness in adolescents after four weeks of strength training. Methods: 19 adolescents with sleep problems recruited in the Federal Institute of Pernambuco, were subject to anthropometric evaluations as well as those for body composition assessment, a 1 repetiti

46. Evaluation of anaerobic threshold in non-pregnant and pregnant rats
ABSTRACT Several studies present different methodologies and results about intensity exercise, and many of them are performed in male rats. However, the impact of different type, intensity, frequency and duration of exercise on female rats needs more investigation. From the analysis of blood lactate concentration during lactate minimum test (LacMin) in the s

47. Fasting: a major limitation for resistance exercise training effects in rodents
Protocols that mimic resistance exercise training (RET) in rodents present several limitations, one of them being the electrical stimulus, which is beyond the physiological context observed in humans. Recently, our group developed a conditioning system device that does not use electric shock to stimulate rats, but includes fasting periods before each RET ses

48. Densidad y manejo de ejes en plantas injertadas de tomate indeterminadas en invernadero
ABSTRACT Grafting in tomato is a regular production practice aimed to control vascular diseases. Even though grafted plants are more expensive, when a vigorous rootstock is used the plants can be trained using multiple leading shoots, reducing the number of plants per hectare. Seeking to reduce direct labor cost and the cost of the plants, this experiment te
