O tipo de esporte praticado determina o nível de atenção seletiva em adultos jovens

The main purpose of this study was to determine the differences in selective attention between people who regularly practiced different forms of physical-sports activity. The sample consisted of a total of 1,038 participants, 68.30% (n=709) being women and 31.70% (n=329) being men, aged between 20 and 29 years (M ± SD = 22.54 ± 2.35). The evaluate selective attention, a computerized numerical cross-out test (a 5x5 matrix) was used, which is part of the Attentional Processes software and is hosted on the MenPas 1.0 Psychosocial Assessment Platform. (www.menpas.com). The results highlighted the existence of statistically significant differences between the types of sport in the execution time of the test performed. Specifically, individual sports practitioners spent more time performing the task than those who performed team sports (Z= −2.46; p= .014, Cohen'sd= .23, 95% CI (.07, .38)) or adversary (Z= −2.11; p= .035, Cohen'sd= .19, 95% CI (.01, .38)). Specifically, those who played paddle tennis and soccer were the ones who obtained the best execution times. The results obtained highlighted that the type of sport practiced could have a differential impact on cognitive development, specifically on selective attention.

Luteolytic failure as the cause of low efficiency in synchronization with prostaglandins in cows under tropical grazing

Our objective was to determine the cause of the low response in the exclusive use of prostaglandin in synchronization programs in cows under tropical grazing compared to the use of progesterone (CIDR). Thirty-five cows with the presence of CL were randomly distributed: first group (GPG; n=23), synchronized with two doses of PGF2α (25 mg, Dinoprost®), with an interval of 12 days. The second group (GCIDR; n=12) synchronized with an intravaginal device (1.9 g progesterone), 2 mg estradiol benzoate and 50 mg progesterone), at day 7 a dose of PGF2α (pm) was administered and at day 8 the CIDR (am) was withdrawn. CL regression, luteolitic failure, progesterone concentration and CL size were determined. The data were subjected to normality test, then to Mann-Whitney U test or independent t student test and chi square. Finding that only 82.6% (19/23) of GPG cows at the second dose of prostaglandins have functional CL (<1 ng/ml of progesterone). Obtaining only in 43.5% of the cows a regression of the CL in the GPG, vs. 91.7% in GCIDR (P=0.0001). In addition, GPG cows showed luteolytic failure of 39.1% and asynchrony of 17.4%. It is concluded, a low efficiency of prostaglandins on the synchrony and regression of CL (luteolitic failure) in cows fed under tropical grazing, attributed to the low efficiency in synchronization programs.Objective: To determine the reason for the low response to the exclusive use of prostaglandin in synchronization programs in cows under tropical grazing compared with the use of progesterone (CIDR). Design/Methodology: Thirty-five cows with CL were randomly distributed in two groups. The first group (GPG; n=23) was synchronized using two doses of PGF2α (25 mg of Dinoprost®) with a 12-day interval. The second group (GCIDR; n=12) was synchronized with an intravaginal device (1.9 g of progesterone, 2 mg of estradiol benzoate, and 50 mg of progesterone); a PGF2α (pm) dose was applied on day 7, before removing the CIDR (am) on day 8. CL regression, luteolytic failure, progesterone concentration, and CL size were determined. Data was subjected to a normality test, followed by the Mann-Whitney U test or independent Student's t-test and chi-square test. Results: Only 82.6 % (19 out of 23) of the GPG cows that received the second dose of prostaglandins have a functional CL (<1 ng mL-1 of progesterone). The CL recorded a regression only in 43.5% of the cows in GPG vs. 91.7% in GCIDR (P=0.0001). In addition, GPG cows showed a luteolytic failure of 39.1% and an asynchrony of 17.4%. Conclusions: The low effectiveness of prostaglandin on the synchrony and regression of the CL (luteolytic failure) in cows fed under tropical grazing can be attributed to the low efficiency of the synchronization programs
