Muscle Triglyceride

The respiratory exchange ratio (RER) is lower during exercise of the same intensity in the trained compared with the untrained state, even though plasma free fatty acids (FFA) and glycerol levels are lower, suggesting reduced availability of plasma FFA. In this context, we evaluated the possibility that lipolysis of muscle triglycerides might be higher in the trained state. Nine adult male subjects performed a prolonged bout of exercise of the same absolute intensity before and after adapting to a strenuous 12-wk program of endurance exercise. The exercise test required 64% of maximum O2 uptake before training. Plasma FFA and glycerol concentrations and RER during the exercise test were lower in the trained than in the untrained state. The proportion of the caloric expenditure derived from fat, calculated from the RER, during the exercise test increased from 35% before training to 57% after training. Muscle glycogen utilization was 41% lower, whereas the decrease in quadriceps muscle triglyceride concentration was roughly twice as great (12.7 +/- 5.5 vs. 26.1 +/- 9.3 mmol/kg dry wt, P less than 0.001) in the trained state. These results suggest that the greater utilization of FFA in the trained state is fueled by increased lipolysis of muscle triglyceride.

Rhinitis Medicamentosa

Eleven patients with rhinitis medicamentosa were treated with twice the recommended dose of a topical nasal corticosteroid for 2 months. Nasal airway resistance (NAR) was measured at rest and after a physical exercise test, before and after the treatment period. NAR at rest was reduced after the treatment because of diminished blood volume in the nasal mucosa. Treatment with topical corticosteroids for short periods may help patients with rhinitis medicamentosa to refrain from using nasal decongestants. Topical nasal decongestants are not recommended for sustained use.

Chokeberry Juice

The aim of the study was to investigate the influence of an increased intake of anthocyanins, contained in chokeberry juice, on the redox parameters in rowers performing a physical exercise during a 1-month training camp. The athletes were randomly assigned to receive 150 mL of chokeberry juice daily, containing 23 mg/100 mL of anthocyanins (supplemented group), or placebo (control group). Before and after the supplementation period, the subjects performed an incremental rowing exercise test. Blood samples were taken from the antecubital vein before each exercise test, 1 min after the test, and following a 24-h recovery period. After the supplementation period, TBARS concentrations in the samples collected 1 min after the exercise test and following a 24-h recovery period were significantly lower in the subjects receiving chokeberry juice than in the control group. In the supplemented group, glutathione peroxidase activity was lower in the samples collected 1 min after the exercise test, and superoxide dismutase activity was lower in the samples taken following a 24-h recovery, as compared to the subjects receiving placebo. These findings indicate that an increased intake of anthocyanins limits the exercise-induced oxidative damage to red blood cells, most probably by enhancing the endogenous antioxidant defense system.

Postocclusive Reactive Hyperemia

Increased oxidative stress and inflammation contribute to impaired walking capacity and endothelial dysfunction in patients with intermittent claudication (IC). The goal of the study was to determine the effects of oral treatment with the antioxidant N-acetylcysteine (NAC) on walking capacity, leg postocclusive reactive hyperemia, circulating levels of inflammatory mediators, and whole blood expression of angiogenic mediators in patients with IC. Following a double-blinded randomized crossover design, 10 patients with IC received NAC (1,800 mg/day for 4 days plus 2,700 mg before the experimental session) and placebo (PLA) before undergoing a graded treadmill exercise test. Leg postocclusive reactive hyperemia was assessed before and after the test. Blood samples were taken before and after NAC or PLA ingestions and 5 and 30 min after the exercise test for the analysis of circulating inflammatory and angiogenic markers. Although NAC increased the plasma ratio of reduced to oxidized glutathione, there were no differences between experimental sessions for walking tolerance and postocclusive reactive hyperemia. Plasma concentrations of soluble vascular cell adhesion protein-1, monocyte chemotactic protein-1, and endothelin-1 increased similarly following maximal exercise after PLA and NAC ( P < 0.001). Whole blood expression of pro-angiogenic microRNA-126 increased after maximal exercise in the PLA session, but treatment with NAC prevented this response. Similarly, exercise-induced changes in whole blood expression of VEGF, endothelial nitric oxide synthase and phosphatidylinositol 3-kinase R2 were blunted after NAC. In conclusion, oral NAC does not increase walking tolerance or leg blood flow in patients with IC. In addition, oral NAC prevents maximal exercise-induced increase in the expression of circulating microRNA-126 and other angiogenic mediators in patients with IC.

Before And After

The aims of the present study are twofold: 1) to investigate whether heart rate recovery (HRR) after a cycle ergometry test is affected by exercise training and 2) to test the ability of HRR to replicate the baroreflex sensitivity (BRS) changes that occur in response to an exercise training program in coronary artery patients. We randomized 82 coronary artery patients undergoing a residential cardiac rehabilitation program to an exercise training group (TR; n = 43) and an untrained group (UTR; n = 39). All of the patients underwent an exercise test before and after the rehabilitation program. HRR was recorded at the end of the 1st and 2nd min after exercise. BRS was determined at rest before and after treatment. HRR after the 2nd min was significantly improved in TR patients (−21.4 ± 0.9 beats/min) compared with UTR patients (−17.8 ± 1.2 beats/min) at the end of the training program. Improvement in HRR paralleled that in BRS in TR patients (from 3.2 ± 0.3 to 5.3 ± 0.8 ms/mmHg; P < 0.001), whereas no significant change was evident in UTR patients (from 3.5 ± 0 to 4.0 ± 0.4 ms/mmHg; P = 0.230). Our data show that HRR in the 2nd min after the cessation of a cycle ergometer exercise test increased in coronary artery patients after an exercise training period. This result confirms the positive effect induced by exercise training on HRR and extends the conclusions of previous studies to different modalities of exercise (i.e., cycle ergometer). HRR might provide an additional simple marker of the effectiveness of physical training programs in cardiac patients.

Abstract Purpose To examine the reaction of endothelium, assess through changes of circulating blood markers of endothelial function: the stable end products of nitric oxide (NOx), S – nitrosothiols (RSNO – reservoir for bioavailable nitric oxide), dimethylarginine (ADMA) and symmetric dimethylarginine (SDMA) that promotes exercise training in female and male patients (pts) with heart failure with preserved ejection fraction (HFpEF). Methods A total of 78 pts with HFpEF were enrolled in the study: 43 male (M group) and 35 female (F group). In all pts, before and after a short-term supervised 3 weeks exercise training at residential center values of NOx, RSNO, ADMA and SDMA were determined and exercise test was performed. Results After 3 weeks of exercise training NOx increased significantly in both groups: in M group (from 34.4±7.5 to 42.3±9.5 μmol/l, P&lt;0.001), and in F group (from 31.3±6.8 to 41.5±7.2 μmol/l, P&lt;0.001), as well as RSNO: In M group RSNO increased from 3.6±1.7 to 4.6±1.9 μmol/l (P&lt;0.05) and in F group from 3.1±1.5 to 4.2±2.2 μmol/l (P&lt;0,05). Increase in NOX and RSNO after exercise training was higher in F than in M group: NOx 32,6% vs 22,9%; RSNO 35,1% vs 27%. Value of ADMA as well of SDMA decreased in both groups after 3 weeks: ADMA in M group from 0.315±0.09 to 0.278±0.12 μmol/l (by 11.7%; ns), and in F group from 0.342±0.08 to 0.297±0.13 μmol/l (by 13.1%; ns); SDMA in M group from 0.269±0.08 to 0.234±0.09 μmol/l (by 13%; ns), and in F group from 0.285±0.09 to 0.245±0.10 μmol/l (by 14%; ns). After 3 weeks, level and duration of exercise test were significantly higher in M (both P&lt;0,001), as well as, in F group (both P&lt;0.001), compared to baseline values. Conclusions There was no gender difference in the way of endothelial response on exercise training in pts with HFpEF. Exercise training induced favorable modification of endothelial function, expressed through significant increased of NOx, RSNO and decreased of ADMA, SDMA in male as well as in female pts. Those positive changes in endothelial function were associated with significant improvement in exercise capacity. Some higher percentage of NOx and RSNO increase in women suggests that they have more pronounced benefit of exercise training than men. Funding Acknowledgement Type of funding source: None
