Comparison of Ventilatory and Blood Lactate Thresholds in Elite Soccer Players

Despite a long research history, the lactate threshold continues to be widely controversial field. Notwithstanding controversies and influence of multiple determinants, estimation in sports has been considered one essential parameters prescription training intensity, load monitoring, perfor- mance prediction. The study aimed compare anaerobic ventilatory thresholds as determined by different methods elite soccer players. consisted twenty-five division 1 players were separated into two groups based on their run times treadmill. Group (age 24.38±7.33 years, height 180.33±7.03 cm, weight 75.53±7.68 kg) who completed more than 17 minutes treadmill, while group 2 25.11±6.07 182.11±10.03 79.72±7.54 those less minutes. an incremental maximal cardiopulmonary exercise testing from which determined. Furthermore, measurements blood samples obtained every 3 after completing each stage test, with total 141 completed. Multivariate tests indicated no significant differences speeds calculated thresh- old methods. These findings suggest that (VT2) can used alternative invasive measurements. Therefore, identifying point without utilizing inva- sive procedure enhances potential application VT2 or respiratory compensation point.
