Texto completo- Finns det någon skillnad i upplevd stress hos kvinnor som deltar på lågintensiv träning i form av promenader jämfört med kvinnor som deltar på högintensiv träning i form av löpning? Finns det någon skillnad i upplevd stress hos kvinnor som deltar på högintensiv träning i form av löpning jämfört med kvinnor som inte tränar alls? Finns det någon skillnad i upplevd stress hos kvinnor som deltar på lågintensiv träning i form av promenader jämfört med kvinnor som inte tränar alls? Metod: Studien är en tvärsnittsstudie, genom enkätundersökningar har skillnader i upplevd stress jämförts på kvinnor med medelålder 39,03 år ( ± 14,44), som antingen tränat högintensivt eller lågintensivt. Resultaten har jämförts med en referensgrupp bestående av kvinnor som inte tränar alls. Perceived Stress Scale-10 (PSS10) inklusive tio stycken intensitets-frågor för inklusion i studien skickades ut via sociala medier, Facebook. Resultat: En signifikant skillnad sågs vid jämförandet av kvinnor som tränar högintensivt och referensgrupp, (p=0,001), poängmässig skillnad i PSS10; 7,67 poäng. Ingen signifikant skillnad redovisades mellan högintensiv och lågintensiv grupp (p=0,737), detsamma gällde lågintensiv och referensgrupp (p=0,081). Slutsats: Högintensiva kvinnor hade reducerad upplevd stress jämfört med kvinnor som inte tränade alls. Ingen skillnad i upplevd stress kunde urskiljas mellan kvinnor som tränar lågintensivt och kvinnor som tränade högintensivt. Samma gällde kvinnor som tränade på låg intensitet jämfört med kvinnor som inte tränade alls, ingen skillnad i upplevd stress.
Purpose and aims: The aim is to study if different exercise-intensities affects perceived stress in Swedish women. This study will answer the following questions:
- Is there a difference in perceived stress in women who participate in low-intensity exercise in the form of walking compared to women who participate in high-intensity exercise in the form of running? Is there a difference in perceived stress in women who participate in high-intensity exercise in the form of running compared to women who do not exercise at all? Is there a difference in perceived stress in women who participate in low-intensity exercise in the form walking compared to women who do not exercise at all? Method: The study is a cross-sectional study, through questionnaires, differences in perceived stress have been compared in women with a mean age of 39,03 years (± 14,44), who either exercised with high intensity or with low intensity. The results have been compared to a reference group consisting of non-training women. Perceived Stress Scale-10 (PSS10) together with ten intensity-questions for inclusion in the study was sent out via social media, Facebook. Results: A significant difference was detected in the comparison of the high intensity group and the reference group, (p=0.001), score difference in PSS10; 7,67 points. No significant difference between the high-intensity group and the low-intensity group (p=0.737), the same applied to the low-intensity group and the reference group (p=0,081). Conclusions: Women who participated in high intensity exercise had reduced percieved stress compared to women who did not exercise at all. No difference in percieved stress was observed between women who participated in low intensity exercise and women who participated in high intensity exercise. Similarly, no difference in percieved stress in women who participated in low intensity exercise and women who did not exercise at all.

Texto completoAlthough horses can present exceptional responses during stress situations in nature, it was raised the possibility that racehorses under certain stress conditions could develop changes that may affect their health and welfare. Alterations of the number and function of cells that are involved with the defense response, mainly neutrophils and lymphocytes populations were verified. Thirty Thoroughbred racehorses housed at the Jockey Club de São Paulo, in São Paulo, Brazil, were used in the present study. The animals were divided in two groups and blood samples were collected at different moments of their routine. In group I, the samples were collected eleven days before race (-11d), immediately after race (0d), one day (+1d), two days (+2d) and three days after race (+3d). In group II, the samples were collected eight days before race (-8d), immediately after race (0d), one day (+1d) and five days after race (+5d). Phagocytosis assay and oxidative burst activity of neutrophils, serum cortisol determination, apoptosis and lymphocyte proliferation assay and haematology tests were performed. The percentage and intensity of phagocytosis functions decreased in samples collected immediately after race, in both groups of animals. The mean values of oxidative burst activity of samples collected immediately after race, from animals of group I also decreased. Statistically significant differences between the results were obtained in relation to the apoptotic cells, when compared on different moments and the same occurred in Relation to the lymphocyte proliferation values. The mean values of serum cortisol levels increased at the moment immediately after race when compared with the values of the other moments, in both groups of animals. In relation to the haematologycal values, the percentage of neutrophils was increased at the moment immediately after race when compared with the other moments. Even though a transitory reduction in the neutrophils function has occurred, the adaptive function was not impaired, which suggest that, in spite of the high intensity of this exercise, the short-term race can prevent further damages in well-conditioned and stress-adapted animals

Texto completoPost-Traumatic Stress Disorder (PTSD) is a mental disorder that affects some individuals exposed to high-intensity stress. The heterogeneity in the expression of various symptoms could explain the lack of effective treatment and/or patient relapse. These subtypes of symptoms are associated with specific brain activities; their better understanding appears crucial for the pursuit of more personalized and thus more effective treatment. In this context, the behavior of outbred mice was evaluated through various tests for 28 days after receiving two high- intensity electric shocks. An analysis of behavioral profiles in two steps revealed three phenotypes in animals exposed to high-intensity stress. The first step, based on a composite score of generalized anxiety-like behaviors, allowed for the differentiation of resilient and susceptible animals and the establishment of a severity score for behavioral alterations. The second step, focused on persistent defensive behaviors during different re-exposures to stimuli associated with electric shocks, identified two behavioral phenotypes in susceptible animals: immobile and fleeing. Analysis of the cellular expression of the Fos protein highlighted distinct cellular activations in the amygdala (AMG) and the periaqueductal gray matter (PAG). Specifically, the severity of PTSD- like behavioral alterations is positively correlated with right AMG activation, and susceptible phenotypes are associated with different activations along the anteroposterior axis of the PAG. Sleep analysis also revealed differences among the three animal phenotypes. In particular, rapid eye movement (REM) sleep appears to be a marker of post-exposure resilience but also an indicator of susceptibility to pathology development before exposure. In conclusion, by demonstrating distinct brain activations and differential effects on sleep in the three animal phenotypes, this study highlights the importance of analyzing behavioral profiles in mice. Refinement of analysis methods of this kind should enhance the translational validity of the PTSD model, thus opening new perspectives for more personalized treatments

Texto completoO treinamento intervalado de alta intensidade (HIIT) na comunidade científica tem se tornado muito notório em função da divulgação de estudos experimentais. O HIIT promove adaptações semelhantes aos exercícios de longa duração e baixa intensidade, tais como melhora da capacidade cardiorrespiratória, do metabolismo de respouso, aumento da ventilação pulmonar, entre outros. Porém, estas adaptações são obtidas com duração muito inferior em intensidades máximas ou submáximas, com segundos ou poucos minutos de intervalo. Contudo, a frequente realização pode aumentar a suscetibilidade a lesões, promover a fadiga crônica e overtraining, parcialmente em razão da elevada síntese de espécies reativas de oxigênio (EROs). Estresse oxidativo é um estado de desequilíbrio entre as reações de oxidação e de antioxidação. Entretanto, ainda existem lacunas a serem preenchidas acerca dos efeitos do HIIT sobre o estado oxidativo e danos musculares, sobretudo em modelo animal. O objetivo desta dissertação foi verificar os efeitos do HIIT de curto prazo sobre os biomarcadores de estresse oxidativo e danos musculares em ratos. Desta forma, foram elaborados três estudos: 1. Avaliou-se os efeitos do HIIT de curto prazo sobre os marcadores de estresse oxidativo e danos musculares; 2. Buscou-se caracterizar as respostas dos marcadores de estresse oxidativo cardíaco ao HIIT em ratos. 3. Verificou-se os efeitos de doze sessões consecutivas e em dias distintos de HIIT sobre os marcadores de estresse oxidativo hepático. Nos estudos 1 e 2 foram encontradas alterações significativas em apenas um marcador de dano oxidativo, fato este que não aconteceu no estudo 3. Ainda sobre o estudo 1 não houveram alterações nos marcadores de danos musculares, no entanto houve uma redução significativa num marcador de defesa antioxidante. Nos estudos 2 e 3 não houveram mudanças significativas na capacidade antioxidante. Conclui-se que o HIIT, seja realizado em dias consecutivos ou distinitos, e a depender do tecido pode ou não promover danos hepáticos, cardíacos e musculares em ratos.

The intensity and duration of exercise will strongly influence the physical responses. After high intensity exercise (85% VO2max), the reactive oxygen species (ROS) are numerously generated, which makes an imbalance between the oxidatants and antioxidatants of organism to result in oxidative stress. Oxidative stress can potentially induce immune cell programmed cell death, or called apoptosis after high intensity exercise. However, the possible mechanisms have not been investigated. The purpose of this study was to investigate the effect of consecutive high intensity exercise induced-oxidative stress on leukocytes apoptosis. Twelve volunteers (22.8 ± 2.39 yrs) were recruited into this study. All subjects performed the session of aerobic exercise at an intensity of 85% VO2max for 30 min daily for 3 consecutive days. 20 mL of venous blood samples were collected before first day (D1) of exercise, immediately postexercise on the first day (D1’), preexercise on the third day (D3), immediately postexercise on the third day, the fifth day (D5) and the seventh day (D7). The oxidative stress and apoptosis in leukocytes were measured by flow cytometry, and the transcription and translation of the apoptosis associated genes also were determined by RT-PCR and western blotting. The results showed that exercise at 85% VO2max intensity leaded to a depletion of intracellular glutathione (GSH) (p<.001) and quite often accompanied by a concomitant increase in ROS (p<.001). This phenomenon could contribute to oxidative stress and apoptosis. In PBMC, it is extremely critical steps that both the loss of the mitochondrial transmembrane potential (MTP) (p<.001) and the release of cytochrome c from the inner membrane of mitochondria can potentially trigger caspase cascade activation, then results in apoptosis. As for PMN, not only collapse of MTP and cytochrome c released to cytosol from mitochondria but also CD95 receptor activated particularly (p<.001) could produced caspase cascade. In conclusion, it is proposed that the consecutive high intensity exercise will increase oxidative stress and induce PBMC apoptosis via mitochondria apoptotic pathway, whereas consecutive high intensity exercise induced PMN apoptosis were mediated via both mitochondria and Fas / FasL activated pathways.

Exercises produce free radicals, especially high intensity exercises. Athletes constantly sustain free radical damage due the physical training they must endure over the long run. Under such conditions, health supplements are essential and daily health care products for athletes. Curcumin has superb anti-oxidative effects. The study was designed to investigate the effect of Curcumin supplements on post-exercise oxidative stress. Twelve outstanding basketball players from junior high schools (aged at 16 ± 0.5; height of 173.2 ± 5.2 cm; weight of 68.4 ± 13.6 kg) were randomized into two groups. Each subject had to undergo a two-stage experiment. Before each experiment, subjects were given, in a double-blind design a placebo or Curcumin supplements before performing 6 repetitions of 150-meter, high intensity interval training. Blood samples were collected before, immediately after and 24 hours after the training to analyze the changes in the level of superoxide disimutase, lipid peroxides, creatinine phosphokinase and lactic acid. The exercise intensity was monitored by heart rates and rating of perceived exertion. Data collected was analyzed by two-way ANOVA to test the difference between each variable including superoxide dismutase, lipid peroxides, creatinine phosphokinase and lactic acid. The result showed that: (1) The level of superoxide dismutase in the Curcumin group increased significantly immediate after and 24 hours after exercise; (2) The level of lipid peroxides in the Curcumin group reduced before and after exercise; (3) Curcumin was highly effective in inhibiting the inflammation of muscle fibers. Results from this study indicate that Curcumin had a significant effect on SOD, MDA and CK without directly affecting athletic performance. It could, however, be used as a reference for health care for athletes. Further studies should be conducted for prolonged exercise times and different supplement strategies.

Exercise can improve performance, fitness, and metabolism, as well as modify body-fat ratio. But high-intensity exercise may also induce active oxygen species (AOS). Fish oil, which is one of the ω-3 PUFA series that can decrease TG and influence other plasma lipids, appears to prevent arteriosclerosis and CHD, but some evidence suggests it increases the lipid peroxidation in the cell membrane. Fish oil would then seem to influence the antioxidant defense system that causes injury or disease. This study investigates the effects on the antioxidant defence system of combining high-intensity exercise with fish oil supplementation. Thirty-three healthy males were randomly assigned into eight groups (20.3±1.4 yrs; 64.3±7.9 kg), which were given set combinations of dietary fish oil (9 g per day), exercise (intensity 85-90 % HRmax reserve), anti-oxident supplementation (500 mg Vitamin C and 400 IU Vitamin E per day), and placebos. The experiment lasted 4 weeks in total. Venous samples were obtained prior to exercise and within 5 min after. 4 venous samples were also taken from fish oil groups during the four-week period. Blood from all groups was analyzed for sesuperoxide dismutase (SOD), glutathione peroxidase (GSH-Px), total glutathione (T-GSH), total antioxidant ability (TAA), malodialdehyde (MDA), vitamin C & E, TG, HDL-C, LDL-C from forearm vein. A Generalized Estimating Equations (GEE) method was used for data analysis. Result: in no group was there a significant change in the body weight and body composition of the subjects. In the fish oil groups SOD activity significantly increased 11.27 kU/g-HB(P<.05). Fish oil and vitamin C & E groups saw a decrease in GSH-Px levels, which did not appear in the exercise groups. However, statistical evidence is not sufficient to draw solid conclusions in this area. MDA change increased significantly after exercise in both exercise and dietary fish oil groups (values: 0.12 and 0.27 mmole/ml [P<.05] respectively). The evidence shows that the dosage of fish oil decreased the values of LDL-C and TG (-4.61 mg/dl and -8.85 mg/dl [P <.05] respectively). Exercise increased LDL-C levels (+2.27 mg/dl). Following exercise in the fish oil group, t-GSH increased significantly (36.61Ug/ml [34.2%] [P<.05]). MDA increased significantly after exercise in both exercise-alone and exercise/fish oil groups (+0.12 and +0.27 mmole/ml [P<.05] respectively). Height intensity exercise and fish oil is a real factor that induced more oxidative stress in this study. There is not sufficient evidence to support the claim that oxidative stress decreases after antioxidant supplementation, although there is some indication that this may be true. More research is required. The study concludes that exercise and fish oil separately causes an increase in oxidative stress, and this increase is greater when they are combined. It is also conclude that antioxidant supplementation has no effect on oxidative stress, although it is possible that a larger dosage may produce such an effect.

The purpose of this study was to investigate the effects of three weeks of carnitine supplementation and HIT combination on aerobic capacity and oxidative stress. Ten untrained healthy males were recruited and randomly assigned into carnitine group (25.0±4.4 yr, 80.3±8.5 kg, 170.2±4.3 cm) or placebo group (22.4±3.3 yr, 69.1±11.2 kg, 172.2±6.3 cm). Subjects received carnitine or placebo supplementation 2 g per day for 3 weeks. All subjects also performed the HIT three day per week. The HIT protocol contains 10 bouts of cycling trail at 90%VO2max, with each bout lasting 2 min and separated by 1 min of rest. The increment cycling tests were conducted before and after supplementation. The VO2max and time to fatigue were measured by the increment cycling test. High-intensity interval exercise tests were also performed 48 hours after the increment cycling test. Blood samples were drawn before the test, immediately after test, 1 h and 3 h after test to determine the activities or concentrations of creatine kinase (CK) and uric acid, TBARS,F2-isoprostanes. The result showed that after 3 week of supplementation, VO2max (43.0±2.4 vs. 37.6±5.0 mL/min/kg) and time to fatigue (1563.0±221.0 vs. 1496.0±207.6 sec) significantly increased (p < .05) in carnitine group. However, there were no differences in placebo group. In carnitine group, the values of blood uric acid in high-intensity interval exercise test before supplementation still elevated at 3 h after test (7.8±2.0 vs. 8.8±2.1 mg/dL, p < .05). However, the values returned to baseline after 3 weeks of supplementation (7.8±1.9 vs. 7.7±1.9 mg/dL, p >.05) and uric acid at 1 and 3 hr after test were significantly lower than pre- supplementation (p <.05). In carnitine group, the values of blood TBARS after high-intensity interval exercise test before supplementation significantly elevated as compared to baseline (5.7±0.8 vs. 4.2±0.7 µmol/L,p < .05). However, there were no significant differences after 3 weeks of supplementation (4.6±1.7 vs. 4.3±0.9 mg/dL,p > .05) and TBARS concentrations at post 3 hr after exercise were significantly lower than pre- supplementation (p <.05). In carnitine group, the values of blood F2-isoprostanes in high-intensity interval exercise test before supplementation significantly increased immediately after test, (1328.4±67.5 vs. 1135.5±156.4 pg/ml,p < .05). However, the values returned to baseline after 3 weeks of supplementation (1217.5±235.0 vs. 1179.4±174.2 pg/mL,p > .05) and F2-isoprostanes concentrations immediately after test, at 1 and 3 hr after test were significantly lower than pre- supplementation (p <.05). It is concluded that carnitine supplementation during HIT is benefit to aerobic capacity and reduce the oxidative stress after high-intensity interval exercise.

Purpose: To investigate the effects of recovery with normoxia (20.9%), hypoxia (16%) or hyperoxia (60%) during high-intensity interval training (HIT) on: 1. The training intensity markers (heart rate, blood lactate acid and glucose), as well as biomarkers of oxidative stress [thiobarbituric acid reactive substances (TBARS), lymphocyte mitochondrial transmembrane potential decline (MTP decline), apoptosis and necrosis], metabolic stress (cortisol) and mechanical stress (creatine kinase, CK) after one single bout of HIT. 2. The adaption of training intensity, oxidative stress, metabolic stress and mechanical stress markers after 5 times HIT. 3. The effects of endurance determinants (VO2max, VT, RE, vVO2max and time to fatigue) after 6 times HIT in two weeks. Methods: Twenty four healthy males (age: 22.1±2.5 yrs, height: 173.5±6.5 cm, weight: 73.9±9.6 kg) randomly assigned to hypoxia (16%, Hypo), normoxia (20.9%, Nor) or hyperoxia (60%, Hyper) groups. Participants were asked to perform an incremental running test to fatigue before and after the experiment intervention to measure VO2max, VT, RE and time to fatigue and calculate vVO2max. After the pre-test, participant performed 6 times HIT (7 reptitions, 4-min interval at 90% VO2max, 2-min rest between intervals) with different oxygen concentration provided in rest intervals. In the 1st and 6th HIT, the heart rate, La and Glu were measured before and after the 1st, 4th and 7th reptition during HIT. Blood sample were also collected to measure cortisol, TBARS, CK, lymphocyte MTP decline, apoptosis and necrosis before and immediately, 1 h, 2 h and 48 h after HIT. Training intensity and exercise induced stress biomarkers in single bout of HIT within group were compared by one way ANOVA with repeated measurment. Training intensity, exercise induced stress biomarkers in single bout HIT and endurance determinants after 2 weeks training between groups were compared by one way ANCOVA. Paired t-test was used to compare training intensity and exercise induced stress biomarkers between 1st and 6th HIT. The significant level was set as α = .05. Results: 1. The training intensity markers during HIT were not affected by different oxygen concentration recovery. The CK activity of 2 h and TBARS concentration of 1 h after HIT were no significant difference to before training in Hypo group. The apoptosis of 1 h after HIT in Hypo group was significantly lower than in Hyper group (15.16%±5.22% vs. 22.70%±8.18%, p < .05). In Hyper group, the cortisol concentration did not elevate after HIT. The cortisol of 1 h after HIT in Hyper group significantly lower than in Hypo group (249.8±107.0 nmol/L vs. 362.7±158.2 nmol/L, p < .05). 2. After 5 times adaption of HIT, the heart rate during training in three groups were significantly decreased. The TBARS concentrations of before and immediately, 1 h after HIT in Hypo group were significantly decreased (p < .05). 3. The VO2max、VT and time to fatigue in Hypo group were significantly improved after traing (p < .05), but there was no change in Hyper group. Conclusion: Recovery by 16% hypoxia during HIT could decrease oxidative and mechanical stress as well as decrease the oxidative stress from HIT after adaption. It can also improve endurance determinants. Using hypoxia recovery during HIT may reduce exercise induced damage and increase aerobic capacity.
