deflection point मीनिंग इन हिंदी

The heart rate increases ( approximately ) linearly up to the deflection point, where the heart rate reaches AT ( also known as LT, lactate threshold, in more modern nomenclature ).
The points are plotted on a graph with heart rate on one axis and power ( or some correlated measurement such as running speed ) on the other axis; the graph's deflection point indicates the aerobic threshold.
