The present study utilized a scale that measured Bevan, Hale, and Williams' (2004) serial argumentation goals and associated these goals with the perceived resolvability of the serial argument and serial argument conflict tactics. College students reporting on current and former dating partnerships completed a written survey containing close-ended items. Six of Bevan et al.'s (2004) ten original goals again emerged from data analyses, and the four remaining goals combined to form a single goal. These seven serial argument goals were related to perceived resolvability and conflict tactics in generally expected ways. 相似文献

Clear criteria for maximal oxygen consumption (VO2max) determination in youth are not available, and no studies have examined this issue in girls. Our purpose was to determine whether different peak heart rate (HRpeak) and peak respiratory exchange ratio (RERpeak) cut points affect girls' (N = 453; M age = 13.3 years, SD = .1) VO2max during a maximal treadmill test. A multivariate analysis of variance revealed VO2max (ml kg(-1) min(-1) differed significantly among HRpeak, 180-189 b min(-1) = 34 (SD = .8), 190-194 bmin(-1) = 35 (SD = .9), 195-199 b min(-1) = 38 (SD = .8), 200-204 b min(-1) = 40 ml kg1 x min(-1) (SD = .8), and > or = 205 bmin(-1) = 42 ml kg1 x min(-1) (SD = .7) but not RERpeak. In studies where evidence of a VO2 plateau was examined, peak oxygen consumption (VO2peak) did not differ between plateau and no-plateau groups. Although our results suggest the association between lower VO2peak and lower peak heart rate is a true cardiovascular limit to aerobic energy production, we cannot rule out participant effort. 相似文献

Interpreting change in Body mass index (BMI) among youth by comparison to growth charts can be difficult because of maturation-related changes. The aim of this paper was to evaluate the utility of several alternative methods for assessing change in BMI among children. Participants included 1,615 children measured for stature and body mass in first grade and then again the following year. A total of 1,101 students were also assessed in eighth grade. Change was examined using BMI percentiles (BMI%), BMI z-scores, “Percent Over BMI” (BMI50), and the Healthy Fitness Zone continuum, also referred to as BMI85. Youth at lower BMI levels at baseline showed a positive mean change in BMI%/z-score, whereas those at higher levels at baseline showed a negative mean change in BMI%/z-score. These patterns were not seen with BMI50 or BMI85. Assessing change in weight by using BMI% may result in bias so researchers are encouraged to use BMI85 as a more appropriate approach. 相似文献
