A comparison of the point of deflection from linearity of heart rate and the ventilatory threshold in the determination of the anaerobic threshold in Indian boys.

The purpose of the study was to assess whether the point of deflection from linearity of heart rate (HRD) could be used as an alternative method to determine the ventilatory threshold (VT) in Indian (Bengali) boys that represents the determination of the anaerobic threshold (AT), and also to standardize an exercise test to be effective in eliciting AT in Indian (Bengali) boys by using HRD. Twenty six (26) boys with a mean age of 12.8 (+/-1.

Coronary artery disease risk factors & their association with physical activity in older athletes.

Objective: To evaluate the effects of present-day physical activity on selected coronary artery disease (CAD) risk factors of older former athletes and to compare these selected risk factors with age-matched older non-athletes.

Methods: The selected CAD risk factors were compared among the active older athletes ( n= 52; 45.9 +/- 4.
