Abstract :

The number of training sessions is an important factor in exercise training. Therefore, this study was aimed at investigating the effect of eight weeks of low and high volume HIIT training on lactate response and some performance indicators of Canadian canoe rowers. Sixteen female rowers invited to the Canadian Canoe National Team Camp were randomly divided into two groups: low frequency interval training and high frequency interval training. Rowing ergometer and respiratory gas analyzer were used and at the same time, physiological variables of aerobic function including maximum oxygen consumption (VO2max), minimum speed to reach maximum oxygen consumption (vVo2max) and exhaustion time (Tmax) were measured. Intense intermittent training was performed in both groups in the form of 6 one-minute rowing sessions with 100% vVo2max and with an increase of two rounds per week. The difference was that the low-frequency group practiced 3 sessions per week and the high-frequency group practiced 6 sessions per week. Exercises were performed for eight weeks. Data were analyzed by paired t-test and independent t-test. Significance between variables was considered at the level of P≤0.05. The results showed a significant difference in lactate, VO2max, vVo2max and Tmax between pre-test and post-test of both high-volume periodic training and low-volume periodic training. However, no significant difference was observed in the post-test values ​​between the two groups in any of the variables (P≤0.05). Due to the lack of significant differences between the two groups, the combination of these two methods at different times of a Canadian canoeing season seems to be helpful in preparing athletes.
