Read More Objective: The aim of the present study was to investigate the effect of 10-week negative energy balance (NEB) methods on adipocyte size and adiponectin levels in different abdominal fat depots as well as glucose and lipid variables and insulin resistance in high-fat-diet obese male wistar rats. Methodology: Study sample were consisted of sixty-four Wistar male rats (average weight; 194.5±12.6g). Blood samples were collected at 1st, 18th and 28th weeks after an overnight fasting. After first sampling, remaining 56 rats were randomly divided into control (n=16) and high-fat-diet (n=40) groups. After 18 weeks High-fat-diet group randomly divided into high-fat-diet (HFD) and negative energy balance consisted of calorie restriction, exercise training and combination (exercise training with calorie restriction) subgroups. Negative energy balance subgroups underwent an aerobic training (running) with intensity of 70 to 75% of VO2max, %25 calorie restriction and interval of both methods for 10 weeks. Adiponectin Levels and adipocyte size in retroperitoneal and mesenteric fat depots, insulin and glucose levels and lipid profile were measured. HOMA-IR was also calculated. Results: The results of this study indicated that in comparison to high-fat-diet, negative energy balance methods despite consumption of high fat diet, decreased adipocyte size in retroperitoneal and mesenteric fat depots (P<0.05) and insulin resistance index improved in line with decrease of serum concentrations of insulin, glucose and triglyceride in obese male rats (P<0.05). However although lipid profile improved, only triglyceride concentration significantly decreased (P<0.05). From negative energy balance subgroups only combination showed significant increase in adiponectin levels of studied depots compared to high-fat-diet (P>0.05). Conclusion: This study indicated that negative energy balance methods can actually decrease adipocyte size of retroperitoneal and mesenteric fat depots even with simultaneous consumption of high-fat-diet which is largely congruent with improvement in lipid and metabolic profile Results also indicate a superiority of aerobic training in improving the lipid profile compare to other NEB methods.

Read More Abstract Aim: Various studies have demonstrated that different rest intervals has a significant effect on hormonal, metabolic, and cardiovascular responses. This factor can lead to different muscle damage responses and manipulate training goals. The purpose of this study was to compare the effect of 1 and 3 minute rest intervals between sets and exercises on muscle damage and sustainability of repetition in consecutive exercises. Method: 12 untrained subjects (aged 23.17±2.06 years, height 175±3.55 cm, weight 67.33±8.26 kg, fat 16.67±1.82 percent) volunteered to participate in this study in two resistance exercise sessions with a 2-week recovery between sessions. Exercises order in each session consisted of front leg extension, biceps curl, leg curl, triceps extension, leg press and bench press with 80% of one repetition maximum (1RM) until fatigue. Subjects randomized for 1 and 3 min rest intervals in each session. The levels of CK and AST were analyzed before, 24 and 48 hours after resistance exercises. Also muscle soreness was evaluated by the Shailaja scale (PAS) at before, immediately, 24 and 48 hours after resistance exercises. Variance analysis with repeated measurment, pair sample t-test and Bonferroni post-hoc were used for statistical analysis of data. Results: CK and AST concentration increased significantly after 24 and 48 hours and muscle soreness also elevated immediately, 24 and 48 hours after resistance exercises (P≤0.05), but no significant difference in muscle soreness and enzymes concentration was found between groups at different time points. The results demonstrated that 3 min rest intervals lead to increased repetitions (P≤0.05). Conclusion: Differences of load volume and sustainability of repetitions at different time points of rest intervals are independent of muscle damage responses and muscle soreness. Also, 3 min rest intervals led to repetition sustainability and appropriate recovery. Key words: Biochemical markers, Recovery time, Exercise volume
