The aim of this study was to verify the reproducibility of the lactate minim (LM) test after four weeks of aerobic training, as well as its validity with the maximal lactate steady state (MLSS) in Wistar rats submitted to swimming exercise. Ten rats with 90 days were used. The aerobic and anaerobic capacity was determined by the LM test before and after the training. The protocol of MLSS was also applied before and after the training. Training was accomplished for four weeks, being the first two weeks with a volume of 30 minutes and the other two weeks with a …

International Journal of Exercise Science: Conference Proceedings
This study investigated whether aerobic capacity (AC) in tethered swimming corresponds to maximal lactate steady state (MLSS) and its correlation with 30 min (V30) and 400m (V400) free swimming velocity. Twenty-five swimmers were submitted to an incremental tethered swimming test (ITS) with each stage lasting 3 minutes, initial load 20N, with 10N increments and a 30s interval to collect blood samples and lactatemia ([La-]). The abrupt increase in [La-] against force (F) corresponded to AC (ACBI). The points obtained for [La-] against force (N) were adjusted with an exponential curve model to determine AC corresponding to 3.5mmol.l-1 (AC3.5) and 4.0mmol.l-1 …

Although VO2max is the index which represents maximum aerobic power, the corresponding exercise velocity (vVO2max) can be different in athletes with the same VO2max values. This study investigated associations between absolute (VO2pabs), relative (VO2pre) VO2peak, and vVO2max for aerobic performances determined in the field. Thirteen runners, aged 20.1±2.1 years, height 170±0.1 cm, and weight 66.0±3.7 kg participated from the 13th Armoured Infantry Battalion (Brazilian Army) based in Ponta Grossa, PR, Brazil. Participants were submitted to an exhaustive progressive test in a treadmill with 12km.h-1 initial velocity, 3min stages, and 1 km.h-1 increments. Breath-by-breath gas samples were collected (Parvomedics – TrueOne, …

Inflammatory, Hematological And Oxidative Stress Responses In 160 To 246 Km Ultramarathons, Taisa Belli, Claudio Alexandre Gobatto
International Journal of Exercise Science: Conference Proceedings
Every race with distance higher than marathon is called ultramarathon. There are short ultramarathons, with a distance of 50 to 100km, such as the "Comrade Marathon" in South Africa (89km). On the other hand there are the long ultramarathons ranging from 100 to 1600km. Among these we can highlight the "Western States Endurance Run" (160km) in California/USA; the "Badwater Ultramarathon" (216 km) in California/USA and the "Spartahlon Ultramarathon" (246 km) in Greece. This literature review aimed to verify the inflammatory, hematological and oxidative stress responses particularly induced by these ultramarathons ranging from 160 to 246 km. These races present long …

Submaximal and regular exercise tends to improve the immune response. On the other hand, athletes have a higher incidence of infection of the upper respiratory tract (URTI). The objective of the present study was to correlate the total episodes of URTI with the relative count of circulating neutrophils and lymphocytes in volleyball female athletes, aged 18.92±0.76 years (n=12), within the periods of training. The blood was collected at the end of the periods: Pre-competitive (M1), Competitive-I (M2) and Competitive-II (M3) and the URTI weekly. The athletes participated of 30 weeks of training and competitions. The Pearson correlation coefficient was used, …

Resistive exercise (RE) may induce muscle damage and acute inflammatory response. A single bout of intense resistive exercise may induce transient immunosuppressive effect. However, the manner that the immune system will be challenged depends in great part of the characteristic of the training session. The aim of this investigation was to determine the effect of two different RE methods on acute lymphocytes plasma levels. Young adult men (n= 10, 26.1±6.3 years old; 174.0±5.4 cm height; 76.4±13.3 kg weight; 15.48±5,42 % body fat) with no previous experience in RE were divided into two groups and both performed an exercise session in …

International Journal of Exercise Science: Conference Proceedings
Carcinogenesis is a complex process best characterized as an accumulation of alterations in genes regulating cellular homeostasis. The whole process can be divided into three main stages: initiation, promotion, and progression. It has been observed that moderate and regular physical activity (PA) may prevent cancer, mainly colon cancer (CC), up to 50% in humans. The evidence that PA protects against colon cancer is convincing. Also, PA probably protects against postmenopausal breast cancer and cancer of the endometrium. On the other hand, exhaustive exercise increases free radical DNA oxidative damage, inflammation and depresses immune function, events also related to the increased …

Cellular adhesion molecules (CAMs) such as E-selectin are involved in the rolling, adhesion and extravasation of monocytes into the atherosclerotic plaque. Fortunately regular exercise may improve pro-inflammatory status in individuals with metabolic syndrome. Accordingly, this study was designed to determine the influence of exercise on soluble plasmatic E-selectin levels in women with metabolic syndrome. Sixty adult women with metabolic syndrome according to the criteria reported by the National Cholesterol Education Program Adult Treatment Panel III volunteered for this study. Fourty-five were randomly included in experimental group to perform a 12-weeks aerobic training program, 3 days/week, consisting of warm up (10-min), …

In recent years it has been shown that psychological stress induced by immobilization changes the balance between pro-oxidant and antioxidant factors inducing oxidative damage. Fortunately several studies have reported that regular exercise may reduce oxidative damage. Consequently, the present work was designed to assess the influence of an 8-week moderate intensity swimming training program in psychological stressed rats. To get this goal, sixty 6-8-weeks-old male albino Wistar rats weighing 145-155 g were used in this experimental study.

White adipose tissue (WAT) is the source of pro- and anti-inflammatory cytokines and recently, it recognized as an important source of interleukin 10 production (IL-10). Acute physical exercise induce an anti-inflammatory cytokine profile. However, the effect of chronic physical exercise in the production of IL-10 by the WAT has never been examined. IL-10 and TNF-α were assessed in WAT of rats engaged in endurance training. Animals were randomly assigned to either a sedentary control group (S, n=7) or an endurance trained group (T, n=8). Trained rats ran on a treadmill for 5 days/wk for 8 wk at 55-65% of the …

Physical exercise is known causer of acute traumas in biological structures. Chronically, physical training or can lead to a coherent sequence of traumas leading to Adaptation (Functional Overreaching – FOR) or to an imbalance between stimulus and recovery leading to Overtraining Syndrome (OTS). In the present study we analyzed muscle and hepatic cytokines concentration: Interleukin-6 (IL6), Tumor Necrose Factor-Alpha (TNF-α), Interleukin-1Beta (IL1-β) and Interleukin-10 (IL-10); muscle and serum concentration of glutamate (GLU) and glutamine (GLN); serum concentration of C-reactive Protein (CRP), Alpha-1 Glicoprotein Acid (AGA), Albumin (ALB), Uric Acid (UA), Ferric Reducing Ability of Plasma (FRAP), Creatine Kinase (CK), Red …

Overtraining may outcomes for functional overreaching (FOR), a short term decline in performance that leads eventually to an improvement in performance after recovery, or nonfunctional overreaching (NFOR) when performance decline may be reversed only by a longer regenerative period. Recently we developed a training-overtraining protocol for rats with increased workload: eight weeks of daily exercise sessions, followed by three weeks of increasing daily training frequency (2, 3 and 4 times) with decreasing recovery time between sessions (4, 3 and 2h), characterized by analyses of performance before training (T1) and after the 4th(T2), 8th(T3), 9th(T4), 10th(T5) and 11th(T6) training weeks.

The blood glucose threshold (GT) has been used for the assessment of the aerobic capacity for trained individuals in replace of the blood lactate and ventilatory parameters for anaerobic threshold determination. But, there are no studies with boys. The purpose of this study was to measure the intensity corresponding to the GT in a group of boys. Eight boys (11±1.12 years; 38±6.93 kg; 1.44±0.09 m; 18±1.79 kg/m2) performed a graded maximal exercise test on a cycloergometer to determine the Watts peak (WP), heart rate maximum (HRmax), Watts at GT (GTw) and heart rate at GT (GThr).
