Continuous Light Reverts Physical Exercise Effects On Colon Carcinogenesis Induced By 1,2-Dimethyl-Hydrazine In Rats, Fernando Tadeu Trevisan Frajacomo, Cleverson Rodrigues Fernandes, Ana Paula Farnesi, Tassiana Marini

International Journal of Exercise Science: Conference Proceedings

Colon cancer risk is reduced by appropriate levels of physical exercise. Light exposure during the night conveys endocrine changes on melatonin rhythm produced by pineal gland. This hormone is considered as a potent anti-oxidant with oncostatic properties. Both factors are related to colon cancer, which risk can be estimated by the evaluation of pre-malignant factors of colonic mucosa such as the Aberrant Crypt Foci (ACF). This study aims to verify whether the beneficial effects of physical exercise are related to the activity of the pineal gland. Thus, 40 rats were divided into 5 groups: G0, G1 and G2 were sedentary, …

Reproducibility Of A Vo2max Protocol For Runners Using Treadmill, Thiago Fernando Lourenço, Lucas Samuel Tessuti, Luis Eduardo Barreto Martins, René Brenzikofer

International Journal of Exercise Science: Conference Proceedings

Test protocols applied to runners should reproduce the real training, outdoor race and should be able to unequivocally determine the submaximal parameters such as ventilatory threshold (VT) and respiratory compensation point (RCP). However, classical VO2max protocols are still used for athletes, mainly due to familiarity, and most of them differ in methodological characteristics, such as stage duration and increment size. Other difficulty found is the lack of reliability, which can affect the precision assessment of the athlete’s performance. The aim of this study was to verify the reproducibility of an incremental protocol for the treadmill based on metabolic concepts. Eleven …

Reference Change Values Of Some Current Blood Parameters In Sports Science In Physically Active Subjects, Lázaro Alessandro Soares Nunes, René Brenzikofer, Denise Vaz De Macedo

International Journal of Exercise Science: Conference Proceedings

The training monitoring by blood analysis and performance tests may be useful to improve performance. However, effective interpretation of data should take in account the inherent biological and analytical variation. To verify if the difference between two serial results is significant and biologically relevant it can be calculated the Reference Change Value (RCV) from the following formula: RCV = (2)½ * Zp*(CVA2 + CV I 2)1/2, where: 21/2=to verify difference between 2 moments, Zp=Z score (probability 95% =1.96), CVA=analytical coefficient of variation and CVI=intra-individual coefficient of variation. The difference between two consecutive results compared to a calculated RCV make possible …

Ratings Of Perceived Exertion And Repetition Maximum Test In Elderly Women, Leonardo José De Souza, Leandro Ferreira, Sebastião Gobbi

International Journal of Exercise Science: Conference Proceedings

Physical exertion subjective perception based on Borg scale is commonly used in researches and exercise interventions when the determination of physical effort intensity is important. Borg Scale had been largely used to control aerobic exercise intensity but few studies applied it to control resistance exercise intensity. This study aimed to compare ratings of perceived exertion (RPE) responses and real exertion intensity (based in 1 Repetition Maximum- RM) in elderly women. Thirty-six volunteers (aged 60.2 ± 7.2 years) performed knees flexion and extension movement and after each try were asked to determine their RPE (based on Borg scale CR10). To compare …

Non-Invasive Laboratory Test Used To Predict Aerobic And Anaerobic Performances In Army Runners, Raphael Cailleaux, Cristina Dos Santos, Paulo Eduardo Redkva, Vanessa Holtz Franco

International Journal of Exercise Science: Conference Proceedings

The velocity test is theoretically a non-invasive cheap method for evaluating aerobic capacity (Vcrit) and anaerobic work capacity (AWC). Various authors have validated Vcrit, generally in the field, for predicting aerobic performance. However, the validity of AWC as an anaerobic evaluation tool is still controversial. This study evaluated the capacity of laboratory determined Vcrit and AWC in predicting aerobic and anaerobic performance. Thirteen runners, aged 20.1±2.1 years, height 170±0.1 cm, and weight 66.0±3.7 kg from the 13th Armoured Infantry Battalion (Brazilian Army) based in Ponta Grossa, PR, Brazil were submitted to three exhaustive random efforts on a treadmill at 100%, …
