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 …

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%, …

In cycling the exercise power (w) is a product of cadence (rpm) and kilopounds (kp). The purpose of this study was to check the pedaling frequency influence on critical power (CP) determined using non-exhaustive aerobic capacity test (Chassain, 1986). Adult men (n=2) were submitted to four powers (100, 120, 130 and 150 w) in two different cadences (40 and 70 rpm) in cycloergometer (Monark 894 E). Two exercise bouts lasting 180 seconds by 90 seconds of interval were performed at an equal intensity.
