This study analyzes the performance of knee extension and flexion of Taekwondo and Kickboxing athletes. The power values were extracted through electromyography obtained by an isokinetic dynamometer at 60 degrees per second. These values are resulted from the square of the electromyography signal. The analysis of kick power was made using a modified wavelet algorithm considering values with 95% significance. Both groups presented equivalent power and torque capacity with different training times and experience, on the other hand, the wavelet analysis showed better results in muscular recruitment performance in athletes with more experience, in other words, power is not only performance but also power plus recruitment produces better results. This study uniquely showed that muscular enhancement capacity is not only related to the power capacity of contraction but also to motor coordination.

Tritrichomonas foetus is a flagellate protozoan and the etiological agent of bovine genital tri-chomoniasis [1], which is an infectious vene- real disease. This parasite is usually found as- sociated with the mucosal surface of the uro- genital tract in females or the male preputial and penile membranes. In females, the clinical ma-nifestations may include abortion, with repe- tition of estrus at irregular intervals, vaginitis, cervicitis, endometritis, and pyometra. Parasi- tized males may have a discharge with small nodules in the preputial membrane. After that, the bulls have no clinical symptoms, and are thus an asymptomatic carrier that may spread the infection. Considering that a bull could cover up to twenty females [2], bovine genital trichomoniasis is a serious medical and veteri- nary problem, with economical repercussion for beef and milk production. As T. foetus is an amitochondrial and aerotolerant organism, en- ergy production under low O2 tension in the protozoan is done via hydrogenosome, which, as the name suggests, is the organelle where H2 is generated [3,4,5]. The molecular machinery of mitochondrial cell death is, therefore, absent in this parasite and the mechanism that activates of cell death program is not clear. This review seeks to understand the characteristics of the protozoan parasite T. foetus in order to propose new therapies for animals suffering from this infectious and contagious agent
