Hematological parameters in champion of Brazilian jiu-jitsu paradesport: Case study.

The behavior of biochemical and immunological parameters investigated in the field conditions in athletes is important to influence in the management of recovery and disease prevention as well as, to support the training program, as well as to improve the physical conditioning associated with health and performance. However, for amputee athletes, Brazilian jiu-jitsu paradesport practitioners, there are no published data to date. Thus, the objective of this case study was to quantify the magnitude of biochemical, hematological, and urinary alterations after a simulated fight session in elite athlete with world titles. Outcomes were obtained through blood analysis of samples collected at four different moments (M1-fasting; M2-1.5 hr after caloric intake; M3-Immediately after the simulated fight; M4-24 hr after the simulated fight). Responses triggered by the simulated fight between baseline and after 24 hr were found to increase in monocyte (100%), neutrophil (20%), and insulin (57%) concentrations, while reductions were observed in eosinophils (-50%), lymphocytes (-26.6%), platelets (-22%), cortisol (-50%), and creatine phosphokinase (-45.2%). After 24 hr lactate values returned to baseline levels. The different changes in biochemical and hematological parameters observed constitute responses to acute physical exercise and were according to the level of the high performance athlete. From these data it will be possible to evaluate the periodization, training load, and recovery techniques according to the individual response verified. In addition, these data may be used for comparison purposes within this specific sport, whose literature is still limited.

Effect of phosphate-solubilizing bacteria on phosphorus dynamics and the bacterial community during composting of sugarcane industry waste.

Sugarcane processing generates a large quantity of residues, such as filter cake and ashes, which are sometimes composted prior to their amendment in soil. However, important issues still have to be addressed on this subject, such as the description of bacterial succession that occurs throughout the composting process and the possibilities of using phosphate-solubilizing bacteria (PSB) during the process to improve phosphorus (P) availability in the compost end product. Consequently, this study evaluated the bacterial diversity and P dynamics during the composting process when inoculated with Pseudomonas aeruginosa PSBR12 and Bacillus sp. BACBR01. To characterize the bacterial community structure during composting, and to compare PSB-inoculated compost with non-inoculated compost, partial sequencing of the bacterial 16S rRNA gene and sequential P fractionation were used. The data indicated that members of the order Lactobacillales prevailed in the early stages of composting for up to 30 days, mostly due to initial changes in pH and the C/N ratio. This dominant bacterial group was then slowly replaced by Bacillales during a composting process of up to 60 days. In addition, inoculation of PSB reduced the levels of Ca-bound P by 21% and increased the labile organic P fraction. In PSB-inoculated compost, Ca-P compound solubilization occurred concomitantly with an increase of the genus Bacillus. The bacterial succession and the final community is described in compost from sugarcane residues and the possible use of these inoculants to improve P availability in the final compost is validated.
