1. Do biomarkers have predictive value in the treatment modality of the patients diagnosed with bowel obstruction?
SUMMARY OBJECTIVES: This study aimed to investigate the ability of the biomarkers to predict the surgery treatment and mortality in patients above 18 years of age who were hospitalized with the diagnosis of bowel obstruction from the emergency department. METHODS: This is a 2-year retrospective study. The patients’ demographic data, laboratory paramete

2. Effects of taurine supplementation in elite swimmers performance
Abstract AIM Taurine is considered a semi-essential amino acid characterized by having various physiological functions in the body that modulate mechanisms of action involved in the muscle contraction process, increased energy expenditure, insulin signaling pathway, carbohydrate metabolism, and scavenging free radicals. These functions are crucial for aerob

3. Evaluation of anaerobic threshold in non-pregnant and pregnant rats
ABSTRACT Several studies present different methodologies and results about intensity exercise, and many of them are performed in male rats. However, the impact of different type, intensity, frequency and duration of exercise on female rats needs more investigation. From the analysis of blood lactate concentration during lactate minimum test (LacMin) in the s

4. Bradykinin, insulin, and glycemia responses to exercise performed above and below lactate threshold in individuals with type 2 diabetes
The aim of this study was to analyze the acute responses of bradykinin, insulin, and glycemia to exercise performed above and below lactate threshold (LT) in individuals with type 2 diabetes mellitus (T2D). Eleven participants with a diagnosis of T2D randomly underwent three experimental sessions 72 h apart: 1) 20 min of exercise performed at 120% of LT (120

5. Two water environment adaptation models enhance motor behavior and improve the success of the lactate minimum test in swimming rats
Abstract AIMS This study was designed to investigate the effects of 14 water environment adaptation days on motor behavior and physiological condition of swimming rats. METHODS Sixty male Wistar rats were divided into four groups-baseline (Bl) and control (Co) groups-which did not perform the water environment adaptation; and sub (SubAnT) and (SupraAnT) an

6. Is heart rate variability a feasible method to determine anaerobic threshold in progressive resistance exercise in coronary artery disease?
ABSTRACT Background Recent studies have shown that the magnitude of the metabolic and autonomic responses during progressive resistance exercise (PRE) is associated with the determination of the anaerobic threshold (AT). AT is an important parameter to determine intensity in dynamic exercise. Objectives To investigate the metabolic and cardiac autonomic re

7. Estudo morfoquantitativo da parede da parte ascendente da aorta de ratos wistar idosos treinados em natação na intensidade do limiar de lactato
O envelhecimento está associado à elevação da pressão arterial sistólica, ao aumento da parede do ventrículo esquerdo e também, a uma maior rigidez na túnica íntima e média das artérias devido a diferentes fatores, como a destruição das fibras elásticas. Como forma de prevenir doenças cárdio - vasculares, promover mudanças na estrutura das

8. Utilização do consumo máximo de oxigênio e do limiar de lactato como preditores do desempenho de corredores amadores em corridas de 5km e meia maratona
This study investigated the use of maximum oxygen uptake (VO2max) and lactate threshold (LT) identified by the method of individual anaerobic threshold (IAT) as predictors of 5 km and 21.1 km (half marathon) race performance. Twelve men, amateur runners, volunteered to take part in the study. VO2max was determined using an incremental protocol on a treadmill

9. Determinação do limiar anaeróbio por meio de biomarcadores salivares: cromogranina A como novo marcador de intensidade em natação
CAPITULO 2: Este estudo investigou a variação intra-individual do lactato (sLac), alfa-amilase (sAA) e cromogranina A (sCgA) salivares com relação ao acúmulo de lactato sanguíneo (bLac) durante um teste de exercício incremental máximo em natação. Amostras de sangue e saliva foram coletadas de doze atletas profissionais da natação durante um teste

10. Determinação das zonas de transição metabólica durante a corrida mediante os limiares de variabilidade da frequência cardíaca / Determination of transition metabolic zones during running using hert rate variability thresholds
The aim of the present study was to obtain evidences of validity and reliability of the thresholds of heart rate variability (HRV). Nineteen male subjects, healthy and runners (30,4 ± 4,1 years; 175,9 ± 6,4 cm; 74,3 ± 8,5 kg) performed a progressive maximal test on a treadmill with initial velocity 5 km.h-1 e increases of 1 km.h-1 every 3 minutes (1% slop

11. Associação entre maturação sexual e limiar de lactato em meninas de 10-15 anos / Influence of sexual maturation in lactate threshold in female soccer players
Os limiares de lactato são utilizados para a avaliação da capacidade aeróbia em diferentes idades. Estudos demonstraram que crianças e adolescentes apresentam menores concentrações sanguíneas de lactato ([la]) para mesma carga de esforço do que adultos. Existem evidências de que isto está relacionado ao desenvolvimento maturacional das mesmas. Obj

12. Análise da existência de máxima fase estável de lactato nos exercícios resistidos leg press 45º e supino reto / Analysis of the existance of a maximal lactate steady state on resistance exercises leg press 45° and bench press
The purpose of the study was to verify if there is a maximal lactate steady state (MLSS) for the Leg Press (LP) and Bench Press (BP) exercises and to analyse ventilatory responses ventilation (Ve) and oxygen uptake (VO2), heart rate (HR), blood lactate concentration (BLC) and ratings of perceived exertion (RPE) to those exercises performed on MLSS intensity
