Estudo comparativo do acúmulo de massa seca e macronutrientes por plantas de Zea mays e Ipomoea hederifolia

Two experiments were carried out under greenhouse conditions to study the accumulation and distribution of dry mass and macronutrients in maize and Ipomoea hederifolia. Plants of both species had grown, separately, in pots with sand substrate and irrigation with nutrient solution. Treatments were represented by the times of evaluation, realized in intervals of 14 days, starting at 21 days after emergence (DAE). A maize plant showed slight growth up to 30 DAE, when dry mass allocation was higher in roots and leaves (80%); while an I. hederifolia plant, up to 50 DAE, when the allocation of dry mass was higher in offshoots and leaves (79). Dry mass accumulation was almost five times greater in maize (134 g per plant) than in I. hederifolia (29 g per plant). The average values of N and K contents were greater in I. hederifolia. Maximum accumulations of macronutrients by maize were 1,431; 474; 1,832; 594; 340, and 143 mg per plant, while by I. hederifolia, 727; 52; 810; 350; 148, and 65 mg per plant, for N, P, K, Ca, Mg, and S, respectively. Mean accumulation rate of dry mass and macronutrients by maize plants was crescent up to 87 DAE, reaching the maximum value at 103 DAE; while being crescent up to 121 DAE by I. hederifolia plants, reaching the maximum value at 138 DAE. Thus, beyond the interference on harvesting process, a population of I. hederifolia also can compete with maize crop for nutrients.

Análise da cinética de remoção de lactato em atletas de canoagem slalom

The aim of this study was to verify the kinetics of lactate production and removal in slalom kayak athletes, K1 category, during official competition. Eight male athletes (22,6 ± 4,3 years) participated of the study. For the analysis of lactate, 25µL of capillary blood were collected. The kinetics of lactate removal was performed before the warm-up (Pre), just after the competitors exit from the river (Post 0'), 5 (Post 5'), and 20 (Post 20') minutes. The results demonstrated a significant increase in lactate concentrations (9.8 mmol/l, 9.4 mmol/l and 6.6 mmol/l) at 0', 5' and 20' post respectively, with values of P<0.01. The findings indicate that after 20 minutes the values of lactate reduced significantly (P<0.05) compared to Pre exercise, suggesting that the athletes would indicate good metabolic conditions for the second turn of the race.

Épocas e extensões do período de convivência das plantas daninhas interferindo na produtividade da cultura do milho (Zea mays)

Q field experiment was carried out at the Gralha Azul Experimental Farm/PUCPR, in the municipality of Fazenda Rio Grande-PR, to evaluate the effect of different times and coexistence extension periods of weeds interfering in corn yield. The experiment was arranged in a complete randomized complete block design and the treatments in a 4x5+2 factorial, with four replications. The treatments were as follows: four initial weed control periods (0-0, 0-7, 0-14 and 0-21 DAE) and five restarted weed control periods until the harvest (28, 42, 56, 70 and 84 DAE) and two checks, weedy and weed-free. The experiment was carried out under a no-till system. The period prior to weed interference (PBWI), the start of the critical period of weed interference (CPWI) and the infesting community were evaluated. When the initial weed control period was 0-0 day, the PPWI was at 9 DAE of corn; however, with increasing initial weed control periods (0-7, 0-14 and 0-21 DAE) the period prior to weed interference inncreased in relation to 0-0 day of the initial weed control, evidencing the existence of PPWI-S of 17, 24 and 28 DAE of corn, respectively. Thus CPWI initiates at the end of PPWI-S, the period when weed control is indispensable to prevent a significant reduction in corn yield. Coexistance with the weeds throughout the crop cycle reduced yield in 15%, compared to the weed-free check. Nine species of seven botanical families were assessed in the infesting community. Reduced density and dry mass were verified in the weeds that coexisted with corn, compared to those that grew without it, thus evidencing a suppressive effect of corn over the infesting plants.

O Efeito da Manipulação Miofascial sobre o Limiar Doloroso em Atletas Durante Período Competitivo

Introduction: The myofascial pain syndrome (SDM) is one of the most common causes of musculoskeletal pain. One of the possible treatments for SDM is the type of physiotherapy myofascial manipulation. Objective: This study aimed to analyze the effect of manipulative technique with myofascial pain threshold before and after applying the technique in athletes during competition period. Methods: Participated in the study 62 subjects of both genders, aged between 14 and 38 (19.64 + 4.89), who had myofascial pain syndrome, 32 oh the treatment group and 30 divided equally between control group and the placebo group. All were athletes and operated by the Department of Sport and Leisure in the city of Marilia – SP and were in competitive period. The volunteers were evaluated according to their musculoskeletal symptoms to prove the necessity of performing the technique of myofascial manipulation. Confi rmed the need to assess the pressure pain threshold (LDP) using a digital dynamometer. After the measurement, patients underwent treatment or using the technique of myofascial manipulation, or a sliding surface for the placebo or no treatment for the control group followed by the immediate reassessment of the LDP. Results: The results were normalized by Kolmogrov-Smirnov test (KS). Through the ANOVA test found no differences between the initial LDP thresholds between groups. To compare pre and post LDP of the three groups we used the paired t test. Signifi cant difference (p=0.0001) between the values of pain threshold before and after application of myofascial manipulation for the treated group and not signifi cant for the control group (p=0.45) and placebo (p=0.16). Conclusion: We conclude then that the myofascial manipulation technique is able to increase pain threshold after micro-musculoskeletal injuries in athletes in competitive period.
