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.

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.

Tratamento químico de sementes de milho e o teste de condutividade elétrica

In different crops, the seeds treatment with the use of fungicides and/or insecticides has been performed before the storage or in the seeding moment as a guarantee form of longer conservation period and adequate initial stand. However, it is not known if the various products used for the treatment interfere with test results of electrical conductivity of corn seeds. The experimental design was completely randomized and the analysis carried out in a factorial 5x5x2 with four replications. The treatments consisted of five cultivars of corn (DKB 390YG, DKB 185YG, 2B710, AGN-30A91HX and AL Bandeirante) treated with four insecticides (imidacloprid+thiodicarbe, thiamethoxam, fipronil, fipronil+piraclostrobin+thiophanate-methyl), and the control previously treated by the company with fungicides (fludioxonil+metalaxyl-M e captan) and insecticides (pirimiphos-methyl, deltamethrin e bifenthrin), analyzed in two different times (after treatment and at 35 days of storage). Seeds were subjected to tests of germination, electrical conductivity and water content. The results showed that the treatment of corn seeds with insecticides and fungicides doesn't interfere on the test results of electric conductivity, even if the analysis is made after 35 days of storage of seeds.
