Abstract

Aims: Following the sport activities, the blood homeostasis system, being affected by fibrinolysis and coagulation factors, is changed. The aim of this study was to investigate the effects of high-intensity interval and concurrent (aerobic-resistance) long-term sport courses on the blood fibrinolysis and coagulation parameters in healthy non-athlete young persons.

Materials & Methods: In the semi-experimental study, 30 healthy non-athlete young men were studied in Saqez in 2014. The subjects, selected via simple available sampling method, were randomly divided into three groups including concurrent (aerobic-resistance) trainings, high-intensity interval trainings, and control groups. 8-week trainings (3 times a week) were conducted in both concurrent and high-intensity interval groups. Blood sampling was done before the first session and 30 minutes after the last training session. Data was analyzed by SPSS 19 software using dependent T, one-way ANOVA, and Tukey’s post-hoc tests.

Findings: After the training intervention, the number of platelits and the fibrinogen level significantly decreased in concurrent group. In addition, prothrombin time in high-intensity interval group and the D-dimer level in both training groups significantly increased (p<0.05). The D-dimer concentrations in control and high-intensity interval groups were significantly different. In addition, the number of platelets in concurrent group was significantly different from both control and high-intensity interval groups (p<0.05).

Conclusion: 8-week high-intensity interval and concurrent trainings reduce the promoter coagulation activity in the helthy non-athlete young men, while increase the fibrinolytic activity.

Abstract

Aims: Known by hyperactivity, inattentiveness, and impulsiveness, the attention deficit hyperactivity disorder (ADHD) is considered as a behavioral disorder in the children, as well as in the adolescents. The disorder might also damage their motor skill procedure. The aim of the study was to determine the effectiveness of 6-week high intensity interval exercise on the serum dopamine levels and the improvement of perceptual-motor performance in boys with ADHD. 

Materials & Methods: In the controlled pretest-posttest semi-experimental study, 20 adolescent male students with ADHD of the eastern Tehran schools were studied in 2015. The subjects, selected by random sampling method, were randomly divided into two groups including experimental (n=10) and control (n=10) groups. 6-week high intensity interval training (3 days a week) was conducted in experimental group. The anthropometric indices, dopamine levels, and perceptual-motor performance scores were measured both at the beginning and at the end of the course. Data was analyzed by SPSS 16 software using paired T and independent T tests.

Findings: In the experimental group, the dopamine levels significantly increased at the posttest stage compared to the pretest (p=0.01), while BMI (p=0.001) and body fat percentage (p=0.002) significantly decreased. In addition, the motor skill score significantly increased in experimental group (p=0.001). No variable was significantly changed in control group during the 6 weeks (p>0.05).

Conclusion: 6-week high intensity interval exercise improves perceptual-motor performance and increases serum dopamine levels in boys with ADHD.

Abstract

Aims: The high concentration of Interleukin-1 beta (IL-1β) and Tumor Necrosis Factor- α (TNF-α) is an important risk factor for developing cardiovascular disease. The purpose of this study was to investigate the simultaneous effect of High-Intensity Interval Training (HIIT) and the use of flaxseed oil with different doses on the serum levels of TNF-α and IL1β in rats.
Materials & Methods: In this experimental study, 30 Wistar rats were randomly divided into six groups: control, training, 10mg/kg supplement, 30mg/kg supplement, training with 10mg/kg supplement and training with 30mg/kg supplement. The groups performed High-Intensity Interval Training (HIIT) for 10 weeks and received flaxseed oil extracts. Data were analyzed by one way ANOVA and LSD post hoc test.
Findings: Serum levels of IL1β in the training group and training groups with doses of 10 and 30mg/kg of extract were significantly lower than the control group. Serum levels of IL1β in the training group with 30mg/kg of extract, was significantly lower than group with 10mg/kg of extract. Also, serum levels of TNF-α in the training group, training groups with doses of 10 and 30mg/kg of extract and group with 30mg/kg of extract were significantly lower than the control group. Serum levels of TNF-α in the training group with 30mg/kg of extract were significantly lower than other groups (p<0.05).
Conclusion: High-Intensity Interval Training (HIIT) and consumption of flaxseed oil for 10 weeks
have interactive effects on reduction of serum levels of TNF-α and IL-1β in rats.

Abstract

Aims: Type 2 diabetes is the result of complex interactions between genetic and environmental factors that affect fat and glucose metabolism. The purpose of this study was to determine the effect of periodic exercise and resveratrol supplement on the expression levels of Pparg Coactivator 1-Alpha (PGC-1α) and Pyruvate Dehydrogenase Kinase (PDK4) genes in gastrocnemius muscle of old rates with type 2 diabetes.
Methods & Materials: 42 male rats (mean age= 40-50 weeks; mean body weight= 250-300 g) were randomly divided into 6 groups: healthy-control, diabetic-control, Diabetic+Periodic Exercise, Diabetic+Supplement, Diabetic+Periodic Exercise+Supplement and Saline. The type 2 diabetes was induced by intraperitoneal injection of Streptozotocin (50 mg/kg body weight). The exercise protocol consisted of 10 sets of 1-min activities at 50% intensity and a 2-min rest period between sets, and each week the speed was increased by 2 meters per minute. The exercises were performed for eight weeks. Resveratrol supplement was injected intraperitoneally daily at a dose of 20 mg/kg body weight. The expressions of PDK4 and PGC-1α in the gastrocnemius muscle were measured by real time Polymerase Chain Reaction (PCR) method. 
Findings: highest expression level of PDK4 and PGC-1α genes in gastrocnemius muscle was observed in the diabetic group received both periodic exercise and Resveratrol supplement and the lowest level was reported in the diabetic-control and saline groups.
Conclusion The combination of resveratrol supplementation and periodic exercise can have beneficial effects on PDK4 and PGC-1α expression levels in the gastrocnemius muscle of old rats with type 2 diabetes and reduce the risks of diabetes-related complications.

Abstract

Aims: Non-Alcoholic Fatty Liver Disease (NAFLD) is the most common chronic liver disease, often reported in patients with inflammatory bowel disease. This study aimed to investigate the effects of High-Intensity Interval Training (HIIT) and probiotic use on the expression of interleukin-10 and interferon-gamma genes in intestinal tissue in an animal model of fatty liver.
Methods & Materials: In this experimental study, 40 male Wistar rats (weighing 200-250 g) were selected. The study rats were randomly divided into 5 groups, including healthy control, fatty liver, fatty liver + HIIT, fatty liver + probiotic, and fatty liver + HIIT + Probiotics. Oral tetracycline was administered at a dose of 140 mg/kg of body weight (as a solution in 2 mL of water) for 7 days with fatty liver. HIIT was performed on tape 5 times a week for 5 weeks. The obtained data were analyzed using One-way Analysis of Variance (ANOVA) and Tukey post-hoc test at the significant level of P<0.05.
Findings: The present research results suggested that the expression of interleukin-10 and interferon-gamma genes in the intestinal tissue of steatosis mice in the fatty liver group was significantly higher than in the healthy control group (P=0.001). HIIT and probiotic use significantly reduced the expression of interleukin-10 and interferon-gamma genes in the intestinal tissue, compared to the fatty liver group (P=0.001).
Conclusion: According to the obtained data, HIIT and probiotic consumption can help modulate the expression of genes involved in the innate immune system of intestinal tissue caused by fatty liver.
