Answer to Question #224306 in Human Anatomy and Physiology for cutie

Question

Equations for predicting VO₂ max

Males: VO₂ max (ml/kg/min) = 111.33 – 0.42 (pulse rate: beats/min) Females: VO₂ max (ml/kg/min) = 65.81 – 0.1847 (pulse rate: beats/min)

ValidityUsing VO₂ max as the criterion, correlation coefficients of -0.75 and -0.72 were found for college age women and men, respectively.
Question: Reliability

Coefficients of 0.92 and 0.89 were found for college age women and men, respectively.

Answer 1

Results:

There were 80 participants in the study of which 40 were males and 40 were females. The mean

age of the participants was 19.49±1.62 years. There was no significant difference in the age (p=0.450), weight (p=0.178), basal diastolic blood pressure (p=0.282), and academic percentage (p=0.371) of male and female students. Statistically, a significant difference was found in height (p<0.001), BMI (p=0.012), basal pulse rate (p<0.001), basal systolic blood pressure (SBP) (p=0.003), basal pulse pressure (PP) (p=0.019), basal mean arterial pressure (MAP) (p=0.047), hours of study per day (p=0.010) and hours of sleep per day (p=0.040) among males and were compared, which was found significantly higher in males than in females (p <0.001). When the study participants were categorized as per the fitness scale, it was observed that more males fell under the good and excellent category whereas more females were in the average and good category.

The result of the study showed negative correlation of BMI (r = -0.339), obesity category (r = -0.275), obese vs non-obese (r = -0.264) and basal pulse rate (r = -0.456) with VO2max and positive correlation of height (r = 0.592) and hours of study (r = 0.309) with VO2max. No correlation was found between weight and VO2max, basal blood pressure and VO2max, academic percentage and VO2max and

hours of sleep and VO2max.
