Effect of mathematical modelling on determining lactate minimum test parameters before and after seven weeks of monitored training
Conclusions The results of the present investigation demonstrate that lactate minimum test parameter determination after seven weeks of training is not dependent on the mathematical modelling method used; however, further investigations are required regarding the linear 1 model because significant relationships were not observed with the other models both before and after the training period.

Conclusion It seems that autonomic control, as evaluated by post-exercise HR, was not associated with body fat in our cohort of apparently healthy normal-weight and obese men and women. When monitoring and interpreting post-exercise HR in real-life circumstances among healthy men and women, one should not focus attention on their body composition. (Source: Science and Sports)

Influence of waterpipe smoking on hematological parameters and cognitive function before and after supramaximal exercise
Conclusion Long-term WP smoking resulted in significantly greater hematological indices potentially reflective of greater inflammation. Despite these hematological differences, similar group responses were observed during stress (i.e. supramaximal exercise) indicating that long-term WP smoking may have limited impact on cognitive function via hematological changes. Future studies may elucidate the impact of long-term WP smoking on cardiovascular and cognitive function. (Source: Science and Sports)

Effects of thermoneutral water, cold-water and contrasting water temperature immersions on lower limb vein cross-section
Conclusion Hydrostatic pressure, which is the same in the three immersion conditions, leads to an increase of the common femoral vein (deep venous system) cross-section no matter the water temperature. Conversely, the changes in great saphenous vein cross-section (superficial venous system) appear related to water temperature variations. This is probably related to thermoregulation mechanisms, which induce modifications in skin blood flow. (Source: Science and Sports)
