Utilização da distância total percorrida no teste específico de hoff como preditor da velocidade de limiar anaeróbio no futebol

OBJECTIVE: To verify the use of maximal running distance performed on Hoff test to predict the anaerobic threshold speed (sAnT). METHODS: Ten young soccer players (age of 17 ± 1 years and body mass of 64.3 ± 2.1 kg) were subjects of the study. The subjects performed 12-min test, lactate minimum test to estimate the anaerobic threshold speed and a field test called Hoff. The purpose of Hoff test was to cover the maximum distance during a period of 10min moving a soccer ball through the track by dribbling. RESULTS: The distance covered during 12-min was 2673.2 ± 64.7 m, the sAnT was 11.6 ± 0.3 km.h-1 and distance covered during test Hoff test was 1458.7 ± 49.6 m. The distance covered during Hoff test was not significantly correlated with sAnT (r = -0.20; P > 0.05) and distance covered during 12-min test (r = -0.15; P > 0.05). The sAnT did not differ of speed correspondent 90% at 12-min speed and they were statistically correlated (r = 0.65). CONCLUSION: Thus, we concluded that maximal distance covered during Hoff test cannot provides a valid prediction of the anaerobic threshold speed.

Teste de condutividade elétrica em sementes de Bowdichia virgilioides Kunth

The aim of this study was to adapt the methodology of electrical conductivity (EC) test and determine the physiological quality of seeds of B. virgilioides. Seeds were separated into three batches according to tegument color (1-yellow, 2-orange, and 3-red/black). The EC test analyzed three quantities of seeds (25, 50 and 100), three volumes of water (25, 50 and 100 mL), and six times of seed imbibition (12, 24, 36, 48, 60 and 72), at 25 °C with 6 replications. Germination test was employed to compare the results. The EC test allowed the differentiation of batches in three levels of vigor - the same was observed in germination test: batch 1 presented the best seed vigor, followed by batches 2 and 3. The use of 25, 50 or 100 seeds imbibed in 50 mL of water for 24 hours is recommended.

Percepção viso-motora de escolares com Transtorno do Déficit de Atenção com Hiperatividade

PURPOSE: The aim of this study was to characterize and to compare the visual-motor perception of students with Attention Deficit with Hyperactivity Disorder (ADHD) with students with good academic performance. METHODS: Forty students from 2nd to 5th grades of an elementary public school, male gender (100%), aged between 7 and 10 years and 8 months old participated, divided into: GI (20 students with ADHD) and GII (20 students with good academic performance), paired according to age, schooling and gender with GI. The students were submitted to Developmental Test of Visual Perception (DTVP-2). RESULTS: The students of GI presented low performance in spatial position and visual closure (reduced motor) and inferior age equivalent in reduced motor perception, when compared to GII. CONCLUSION: The difficulties in visual-motor perception presented by students of GI cannot be attributed to a primary deficit, but to a secondary phenomenon of inattention that interferes directly in their visual-motor performance.

Teste de tetrazólio para avaliação da qualidade de sementes de Tabebuia roseoalba (Ridl.) Sandwith - bignoniaceae, submetidas ao armazenamento

The species of Tabebuia are propagated sexually, and the use of high-quality seeds is crucial to achieving success in restoration of degraded areas, timber and medicinal production. Thus, the use of rapid tests in programs to control seed quality is an essential tool for the assessment of their physiological quality. The objectives of the present study were to establish the methodology for conducting the tetrazolium test in seeds of T. roseoalba and verify seed viability as a function of storage time, evaluating germination parameters and comparing them with the results of the tetrazolium test. The fruits were manually harvested at the opening, and fresh seeds and seeds stored up to 24 months were evaluated by tetrazolium test, germination, emergence, length and dry weight of seedlings. The tetrazolium at a concentration of 0.05% at 36 ° C for 24 hours is indicated to assess the viability of T. roseoalba, and during storage germination, length and dry weight of the seedlings are reduced and the germination in nursery is sharply reduced with seed storage in 24 months.

Análise do potencial mutagênico dos esteroides anabólicos androgênicos (EAA) e da l-carnitina mediante o teste do micronúcleo em eritrócitos policromáticos

INTRODUCTION: Anabolic androgenic steroids (AAS) are frequently used by people whose aim to increase muscle mass to obtain a better performance in sports or improve physical appearance. AAS are synthetic derivatives of testosterone, able to promote muscle fibers hypertrophy, increasing intracellular protein synthesis. L-carnitine is a food supplement used to increase energetic production by means of fat acids oxidation. Although there are several works about physiological properties of these drugs, there are few studies about their mutagenic potential. OBJECTIVES: This work evaluated the clastogenicity and genotoxicity of nandrolone decanoate, testosterone decanoate and L-carnitine, in different treatments through the micronucleus test in polychromatic erythrocytes of Wistar rats. METHODS: The animals were submitted to different concentrations and associations of AAS. The positive control received cyclophosphamide 50 mg/kg by intraperitoneal injection and negative control, one ml of saline solution by gavage. The rats were sacrificed after 36 hours of latest application, having the femurs removed and the bone marrow extracted. Material was homogenized and centrifuged. Button cell was pipetted and transferred to slides, which were stained by Giemsa. 1,000 polychromatic erythrocytes were counted per animal, noting the frequency of micronuclei. RESULTS: The Kruskal-Wallis test was performed, with a significance level of 5%, which demonstrated that nandrolone decanoate - three doses of 0,2 mg/kg and 0,6 mg/kg, eight doses of 7,5 mg/kg, L-carnitine - seven doses of 0,4 ml/250 g and 1,5 ml/250 g, testosterone decanoate - 28 doses of 0,075 mg/kg, nandrolone decanoate - eight doses of 7,5 mg/kg associated to L-carnitine and 1 mL and nandrolone decanoate - eight doses of 7,5 mg/kg associated to testosterone decanoate - eight doses of 7,5 mg/kg, showed mutagenic potential. CONCLUSION: The treatments proved to be clastogenic, not being indicated like ergogenic aid.

Contexto escolar: práticas educativas do professor, comportamento e habilidades sociais infantis

Educational practices, behavior problems and children's social skills have been more studied in family context than in school context. This study aimed to compare, from the verbal report, educational practices of regular and special teacher in relation to children's behavior, concerning groups differentiated by reference indication of behavior problems in the classroom by the teacher and sex of the children. This study surveyed fifteen teachers and twenty-eight students (6-9 years), who were grouped in regular teaching (n = 18, kindergarten, elementary) and especial teaching (n = 10). The assessment with teachers was proceeded by using a questionnaire (Q-RSH-Pr) and a semi-structured interview (RE-HSE-Pr). We observed that there is a significant difference: boys as well as children with behavior problems presented more difficulties than others. Their teachers revealed that they use more negative
