The effect of sauna bathing on lipid profile in young, physically active, male subjects

ABSTRACT Introduction: Pre-prandial exercise promotes greater mobilization of fat metabolism due to the increased release of catecholamines, cortisol, and glucagon. However, this response affects how the cardiovascular system responds to exercise. Objective: To evaluate the response of systolic, diastolic, and mean blood pressure, heart rate (HR) and rate-pressure product (RPP) to pre- and postprandial exercise. Methods: Ten physically active male subjects (25.50 ± 2.22 years) underwent two treadmill protocols (pre- and postprandial) performed for 36 minutes at 65% of VO2max on different days. On both days, subjects attended the laboratory on a 10-hour fasting state. For the postprandial session, volunteers ingested a pre-exercise meal of 349.17 kcal containing 59.3 g of carbohydrates (76.73%), 9.97 g of protein (12.90%), and 8.01 g of lipids (10.37%). Blood pressure, HR and RPP were measured before and after exercise. The 2x2 factorial Anova with the multiple comparisons test of Bonferroni was applied to analyze cardiovascular variables in both moments (pre- vs. postprandial). The significance level was set at p<0.05. Results: Systolic (121.70 ± 7.80 vs. 139.78 ± 12.91 mmHg) and diastolic blood pressure (66.40 ± 9.81 vs. 80.22 ± 8.68 mmHg) increased significantly after exercise only in the postprandial session (p<0.05). HR increased significantly (p<0.05) after both protocols (64.20 ± 15.87 vs. 141.20 ± 10.33 bpm pre-prandial and 63.60 ± 8.82 vs. 139.20 ± 10.82 bpm postprandial). RPP had a similar result (8052.10 ± 1790.68 vs. 18382.60 ± 2341.66 mmHg.bpm in the pre-prandial session and 7772.60 ± 1413.76 vs. 19564.60 ± 3128.99 mmHg.bpm in the postprandial session). Conclusion: These data suggest that fasted exercise does not significantly alter the blood pressure. Furthermore, the meal provided before the postprandial exercise may promote a greater blood pressure responsiveness during exercise.

This study analyzed the effect of static stretching on performance during drop jumps. Furthermore, we investigated if a reduction in drop height would compensate the stretching-caused alterations. Ten physically active male subjects performed drop jumps at four different drop heights without static stretching for the optimal drop height determination. After, they performed drop jumps on two drop heights with static stretching previously. The jump height, contact time and reactive strength index were significantly affected by static stretching. However, only the contact time was significantly improved by the reduction in drop height with previous static stretching. Our results suggest that the decrement in performance after static stretching could be partially compensated by a reduction in drop height, which decreases the contact time near a non-stretching jump condition. This can be explained by the lower landing velocity and, possibly, the smaller reduction in the activation of the plantar flexors muscles. In conclusion, the reduction in drop height seems to be interesting after a static stretching session, aiming to expose the athletes to lower impact forces to maintain jump performance.

BACKGROUND & OBJECTIVE: Kisspeptin (KP) and spexin (SPX) are neuropeptides that play a substantial role in metabolism and sexual function. Our objective is to explore the association of spexin and kisspeptin with sperm parameters and lipid profile in the infertile male population. METHODOLOGY: The cross-sectional study was conducted from March 2017 till July 2018 in Aga Khan University Hospital, Karachi, Pakistan, after acquiring ethical approval (4813-BBS-ERC-17). Convenient sampling was applied to recruit 44 normozoospermic subjects as controls and 44 patients with abnormal sperm parameters”. Serum levels of kisspeptin and spexin were measured by enzyme linked immunosorbent assay and Cobas c111 analyzer was used for estimation of high and low density-lipoprotein, triglyceride and serum cholesterol levels. Mann-Whitney U tests and spearman’s rank correlation test were used to analyze quantitative variables, and data was presented by means, standard error (SE) and correlations coefficient, with a statistical significance set at p≤0.05. RESULTS: The mean kisspeptin values of ‘altered sperm parameters’ males 13.23 ± 3.34 were lower than normal sperm parameters 31.89 ± 3.25 (p<0.001). The mean spexin values of altered sperm parameters 383.57 ± 21.09 were less than compared to normal sperm parameters 502.76 ± 19.77 (p<0.001). Correlation of KP and SPX levels was (r-value = 0.332, p= 0.002). There was no significant correlation was found between KP and SPX with lipid profile parameters. CONCLUSION: Spexin and kisspeptin levels observed were higher in male subjects with normal sperm parameters and had a significant positive correlation with each other. There was no impact of spexin on lipid profile and obesity.

Several studies have investigated the effects of fat intake before exercise on subsequent substrate oxidation and exercise performance. While some studies have reported that unsaturated fatty acid supplementation slightly increases fat oxidation, the changes have not been reflected in the maximum oxygen uptake or in other performance and physiological parameters. We selected almonds as a fatty acid (FA) source for acute supplementation and investigated their effect on non-esterified fatty acid (NEFA) values and exercise performance. Five physically active male subjects (age 32.9 ± 12.7 years, height 178.5 ± 3.3 cm, and weight 81.3 ± 9.7 kg) were randomly assigned to take an almond or placebo supplement 2 h before participating in two cycling resistance training sessions separated by an interval of 7–10 days. Their performance was evaluated with a maximal incremental test until exhaustion. Blood samples collected before, during, and after testing were biochemically analysed. The results indicated a NEFA value average increase of 0.09 mg·dL−1 (95% CI: 0.05–0.14; p < 0.001) after active supplement intake and enhanced performance (5389 ± 1795 W vs. placebo 4470 ± 2053 W, p = 0.043) after almond supplementation compared to the placebo. The almond supplementation did not cause gastrointestinal disturbances. Our study suggests that acute almond supplementation 2 h before exercise can improve performance in endurance exercise in trained subjects.
