Data analysis techniques descriptive find out average, normality test, homogeneity post-test, hypothesis testing with t-test st...

BACKGROUND This study examined the effects of different levels of compression (0, 20 and 40 mmHg) produced by leg garments on selected psycho-physiological measures of performance while exposed to passive vibration (60 Hz, amplitude 4-6 mm) and performing 3-min of alpine skiing tuck position. METHODS Prior to, during and following the experiment the electromygraphic (EMG) activity of differen...

The present study was designed to determine the contribution of cross-sectional area ski poles (Sp) total aerodynamic drag during alpine skiing. At three different wind speeds in a tunnel, 10 skiers assumed typical skiing postures (high, middle, and tuck), their frontal assessed with force plate area, along that poles, determined by interactive image segmentation. data collected were utilized e...

This study examines the acute effects of plyometric exercise on 1 repetition maximum (RM) squat performance in trained male athletes. Twelve men (mean age +/- SD: 20.5 +/- 1.4 years) volunteered to participate in 3 testing sessions separated by at least 6 days of rest. During each testing session the 1RM was assessed on back squat exercise. Before all 3 trials subjects warmed up on a stationary...

Fecal sterol has been proposed as a chemical indicator of human fecal pollution even when fecal coliform populations have diminished due to water chlorination or toxic effects of industrial effluents. This paper describes an improved derivatization procedure for simultaneous determination of four fecal sterols including coprostanol, epicholestanol, cholesterol and cholestanol using gas chromato...
