The objective of the study was to determine the effects of tobacco use on selected markers of health and lung function in professional athletes. A total of 108 male professional athletes participated in the study from ten ball game teams in the same sport league in Qatar (age =26.4±5.1 yrs, height =190.6±11.9 cm, and weight =91.5±16.4 kg). The athletes have been playing professionally for about 6.3 years on average. In addition to demographic and tobacco use status, the following clinical variables were measured: resting blood pressure, heart rate, FVC, FEV1 sec, and PEF. The prevalence of tobacco use among the athletes was 27.7%. The FVC, FVC%, and FEV1% were significantly lower among the smokers compared to the nonsmokers (p=0.003, 0.044, and 0.001, resp.). There were no significant differences between cigarettes smokers and nonsmokers in BP, HR, FEV1, FEV1/FVC, PEF, and PEF%. Similarly, those who smoked shisha had lower FEV1% values as compared to those who did not smoke shisha (p=0.001). The decrease of FEV1 and FVC among smokers compared to nonsmokers is similar to what has been reported in the literature about other populations.

Sympathetic Influence

The effect of thyroid status on arterial baroreflex function and autonomic contributions to resting blood pressure and heart rate (HR) were evaluated in conscious rats. Rats were rendered hyperthyroid (Hyper) or hypothyroid (Hypo) with triiodothyronine and propylthiouracil treatments, respectively. Euthyroid (Eut), Hyper, and Hypo rats were chronically instrumented to measure mean arterial pressure (MAP), HR, and lumbar sympathetic nerve activity (LSNA). Baroreflex function was evaluated with the use of a logistic function that relates LSNA or HR to MAP during infusion of phenylephrine and sodium nitroprusside. Contributions of the autonomic nervous system to resting MAP and HR were assessed by blocking autonomic outflow with trimethaphan. In Hypo rats, the arterial baroreflex curve for both LSNA and HR was shifted downward. Hypo animals exhibited blunted sympathoexcitatory and tachycardic responses to decreases in MAP. Furthermore, the data suggest that in Hypo rats, the sympathetic influence on HR was predominant and the autonomic contribution to resting MAP was greater than in Eut rats. In Hyper rats, arterial baroreflex function generally was similar to that in Eut rats. The autonomic contribution to resting MAP was not different between Hyper and Eut rats, but predominant parasympathetic influence on HR was exhibited in Hyper rats. The results demonstrate baroreflex control of LSNA and HR is attenuated in Hypo but not Hyper rats. Thyroid status alters the balance of sympathetic to parasympathetic tone in the heart, and the Hypo state increases the autonomic contributions to resting blood pressure.

Prolonged or intense exposure to heat can lead to a range of health effects. This study investigated heat exposure and heat-related symptoms which sugarcane workers (90 sugarcane cutters and 93 factory workers) experienced during a harvesting season in Thailand. During the hottest month of harvesting season, wet bulb globe temperature was collected in the work environment, and workloads observed, to assess heat stress. Urine samples for dehydration test, blood pressure, heart rate, and body temperature were measured pre- and post-shift to measure heat strain. Fluid intake and heat-related symptoms which subjects had experienced during the harvesting season were gathered via interviews at the end of the season. From the results, sugarcane cutters showed high risk for heat stress and strain, unlike factory workers who had low risk based on the American Conference of Governmental Industrial Hygiene (ACGIH) threshold limit values (TLVs) for heat stress. Dehydration was observed among sugarcane cutters and significant physiological changes including heart rate, body temperature, and systolic blood pressure occurred across the work shift. Significantly more sugarcane cutters reported experiencing heat-related symptoms including weakness/fatigue, heavy sweating, headache, rash, muscle cramp, dry mouth, dizziness, fever, dry/cracking skin, and swelling, compared to sugarcane factory workers. We conclude that the heat stress experienced by sugarcane cutters working in extremely hot environments, with high workloads, is associated with acute health effects. Preventive and control measures for heat stress are needed to reduce the risk of heat strain.

Twenty-four healthy students walked at least four times for 1 hour under each of the four settings: by a busy road; by a busy road wearing ear plugs; in a park; and in a park but exposed to traffic noise (65 dB) through speakers. Particle mass (smaller than 2.5 and 1 µm, PM1 and PM2.5, (respectively)particle number and noise levels were measured throughout each walk. Lung function and exhaled nitric oxide (NO) were measured before, immediately after, 1 hour after, and approximately 24 h after each walk. Blood pressure and heart-rate variability were measured every 15 min during each walk. Air pollution levels reduced lung function levels; noise levels reduced systolic blood pressure and heart-rate variability.

Cardiovascular Changes

Aim. To determine the early predictive factors of cardiovascular changes in professional athletes, depending on the type and intensity of physical activity.Material and methods. A total of 136 male athletes were examined. Of these, 116 were professional athletes (age, 22,07±4,1 years) as follows: freestyle wrestling, judo (n=30), cross-country skiing, biathlon (n=27), powerlifting (n=33), volleyball (n=26). Control group included 20 athletes (age, 17,95±1,5 years) with a history of training less than 3 years. All participants underwent electrocardiography (ECG), echocardiography, cycle ergometry (CE) with assessment of physical performance at a heart rate of 170 bpm (PWC170) and maximum oxygen consumption (MOC). When creating predictive models of early cardiovascular changes, we used logistic regression, stepwise regression and Wald statistics. Differences were considered significant at p<0,05.Results. Predictive models of logistic regression using ROC analysis showed high sensitivity and specificity, a high percentage of correct predictions using data from echocardiography — 86,8%, CE — 80,9%, ECG and other indicators — 83,1%. A stepwise algorithm was used to select prognostic factors determining early cardiovascular changes in young athletes, depending on the stage of sports training, the intensity and type of dynamic and/or static exercise: left ventricular posterior wall thickness (p=0,008), left ventricular mass (p=0,001), stroke volume (p=0,002), end-systolic volume (p=0,001), PWC170 (p=0,025), MOC (p=0,003), recovery time of heart rate (HR) (p=0,029) and blood pressure (p=0,032) after submaximal exercise on a cycle ergometer, body mass index (p=0,029), heart rate (p=0,034), office systolic blood pressure (p=0,009), intraventricular (bundle) block (p=0,046), left ventricular repolarization abnormalities (p=0,010), mild cardiac connective tissue anomalies (p=0,035).Conclusion. The early prognostic factors established by the logistic regression affect the characteristics and risk of cardiovascular changes in each group of young athletes. This demonstrates the need to develop individual medical support programs, further monitoring, evaluation, correction and prevention of identified disorders, taking into account the type of sports, intensity and exercise.

SummaryIn a population of 788 men 54 years of age plasma clotting times, factor II-VII-X activity, factor VIII, fibrinogen, fibrinolytic activity and plasminogen have been compared to anthropomorphic variables, blood lipids, blood sugar, blood pressure, heart rate, lung function and smoking.It was found by multiple regression analyses that fibrinogen, plasminogen and factor II-VII-X activity were correlated to serum cholesterol, and secondary to systolic blood pressure, heart rate and blood sugar.Independent of these correlations, fibrinogen, plasminogen and factor II-VII-X activity were also negatively correlated to FEV1 and VC which are measures of lung function.Smokers have a higher fibrinogen level than non smokers and this is not due to the decreased lung function in smokers. PTT (partial thromboplastin time) carried out in silicone tubes is correlated to serum cholesterol.There is a negative correlation between fibrinolytic activity and weight, subscapular and thorax skinfolds, chest and waist chcumference indicating that obese subjects have a low fibrinolytic activity. There is also a negative correlation between fibrinolytic activity and serum triglycerides but this is insignificant when the effect of obesity is taken into account.

Resting Blood Pressure

Studies with male spontaneously hypertensive rats (SHR) were initiated to determine the hemodynamic relationships associated with the lower resting caudal artery systolic blood pressure (SBP) of endurance-trained SHR populations. After assignment into nontrained (NT, n = 38) and trained (T, n = 38) groups, the T animals were exercised 5 times/wk on a motor-driven treadmill for 12–16 wk at a moderate intensity that ranged from 40 to 70% of their maximum O2 consumption capacity (VO2max). SBP, VO2max, and treadmill run time were determined before the experimental period began and before the animals were instrumented for hemodynamic measurements. At the end of the study, the T rats exhibited significantly lower SBP (NT = 210 +/- 3, T = 200 +/- 3 mmHg) and significantly higher VO2max (NT = 75 +/- 2, T = 83 +/- 2 ml.min-1.kg-1) and run durations (NT = 11.4 +/- 0.4, T = 14.5 +/- 0.3 min). When the animals were anesthetized for insertion of catheters and microprobes for blood pressure and cardiac output (thermodilution) measurements, the T rats had lower values for body mass, heart rate, mean blood pressure, cardiac output, and cardiac index than the NT rats; however, only the body mass and heart rate differences were statistically significant.(ABSTRACT TRUNCATED AT 250 WORDS)

Long Evans

The diabetogenic agent streptozotocin (STZ) was injected intraperitoneally in Long-Evans and arginine vasopressin (AVP)-deficient Brattleboro rats. Twenty-eight days later both strains had a bradycardia and systolic hypotension; STZ-treated Brattleboro rats also had diastolic hypotension. The vasopressin (V1-receptor) antagonist, d(CH2)5[Tyr(Et)]DAVP, had no effect on resting blood pressure (BP) or heart rate (HR) in either strain of rat, indicating the relative maintenance of diastolic BP in STZ-treated Long-Evans rats was not dependent on acute vascular actions of AVP. Captopril caused a modest hypotension in all groups of rats, indicating that BP was not differentially dependent on the renin-angiotensin system in the different groups. In the presence of captopril and the ganglion blocker, pentolinium tartrate, the AVP-mediated recovery in BP was impaired in STZ-treated Long-Evans rats. During administration of d(CH2)5[Tyr(Et)]DAVP and pentolinium, the angiotensin II (ANG II)-mediated BP recovery was smaller in both groups of STZ-treated rats, indicating that this abnormality was not likely to be caused by inhibition of renin release by AVP. The abnormalities in ANG II- and AVP-mediated recovery were prevented by insulin treatment.
