SPEED ENDURANCE (MIDDLE DISTANCE)

This articles show the individual anaerobic threshold (IAT) for middle distance runners develops during the basic training periods in autumn (TP-1; 12 weeks) and spring (TP-2; 8 weeks), and during the competition periods in winter (CP-1; 8 weeks) and summer (CP-2; 16 weeks), depending on subjects' training intensity and volume. Compared to the initial value the running speed was significantly higher for T at IAT for all further measurements. IAT values changed significantly in the trained group only. TP-1 and TP-2 showed the highest increases for IAT is shown to show growth.
