Background: Exercise performance depend on the ability of the cardiovascular system to respond to a wide range of met- abolic demands and physical exertion. Objectives: To investigate the habitual smoking effects in heart rate response and heart rate recovery after step test in ath- letes. Methods: Seventy-eight physically healthy active athletes (45 non-smokers and 33 smokers) aging 27±8years old, participat- ed in this study. All participants completed the International Physical Activity Questionnaire and performed the six-minute step test. Cardiovascular parameters such (resting heart rate, peak heart rate, heart rate at 1 min after testing, heart rate re- covery, recovery time, blood pressure at rest, and post-testing blood pressure) were recorded. Results: Smoker-athletes had higher resting heart rate (76 ± 9bpm vs. 72 ± 10bpm, p<0.05), maximum heart rate (154 ± 18bpm vs. 147 ± 17bpm, p<0.05) and recovery time (7min 25sec ± 6min 31sec vs. 4min 21sec ± 4min 30sec, p<0.05) than non-smoker athletes. Scores from the IPAQ were approximately the same (Μ=7927 ± 10303, Μ= 6380 ± 4539, p<0.05). Conclusion: Smoking was found to affect athletes' cardiovascular fitness. The change of the athletes’ heart rate recovery and recovery time contributes to the adaptation of cardiovascular function in training requirements. Keywords: Smoking; athletes; heart rate recovery; heart rate reserve; six-minute step test.

Introduction: Low cardiorespiratory fitness (fitness) and high levels of adiposity are independently associated with higher levels of blood pressure in adolescents. However, it remains uncertain whether the associations between fitness and blood pressure are due to fitness itself or results from lower levels of adiposity. Moreover, there are no studies that have determined the extent to which adiposity, including central adiposity, moderates the association between fitness and 24-hour ambulatory blood pressure (ABP). Hypotheses: 1. Higher levels of fitness will be associated with lower levels of ambulatory systolic (SBP) and diastolic (DBP) blood pressure after adjusting for adiposity and covariates. 2. With adjustments for covariates, adiposity (body mass index [BMI], waist circumference [WC]) will modify the association between fitness and 24-hour SBP and DBP. Methods: A cross-sectional study was conducted in Houston, TX with a sample of 370 adolescents aged 11-16 years. Demographically, the sample was 54% female, 37% African American, 31% Hispanic, 29% non-Hispanic white, and 3% other ethnic/racial groups. Fitness was assessed by a height-adjusted step test and estimated by heart rate recovery, defined as the difference between peak heart rate during exercise and heart rate two minutes post-exercise. Adiposity was measured using dichotomized values for percentiles of BMI (≥ 85 th ) and WC (≥ 50 th ). Ambulatory SBP and DBP (Spacelabs model 90207) were measured every 30-60 minutes over 24 hours on a school day. Mixed-effects regression analysis was used to test the hypotheses with the following covariates: activity, location, and position at the time of each ABP measurement, height, age, sex, ethnicity, sexual maturation level, and mother’s education level. Results: Hypothesis 1: Each unit increase in fitness was associated with a decrease of SBP (-0.058 mmHg, p = 0.001) and DBP (-0.043 mmHg, p < 0.0001) after adjustment for WC and covariates. Each unit increase in fitness was associated with a decrease in SBP (-0.058 mmHg, p = 0.001) and DBP (-0.045 mmHg, p < 0.0001) after adjustment for BMI and covariates. Hypothesis 2: Fitness and BMI ≥ 85 th percentile (or WC ≥ 50 th percentile) interactions were not significantly associated with ambulatory SBP or DBP after adjustment for covariates. Conclusions: Our findings indicate a small but statistically significant inverse effect of fitness on 24-hour ABP in adolescents, and no evidence of a modifying effect of adiposity on this association. Further research is needed to better understand the protective role of fitness on cardiovascular health in adolescents.

The purpose of this study was to evaluate the effects of a 13-week health-related fitness program on 10 Down syndrome subjects aged 8 to 18. An A-B-A time-series design was used, with data collected every 6 weeks for 43 weeks: The preintervention phase included four data collection points, and the intervention and postintervention phases included two data collection points each. Data obtained included resting heart rate, blood pressure, and results of a step test designed to measure cardiovascular fitness. Analyses of results revealed significant positive changes for resting heart rate (p < .0005), blood pressure (p < .01), and step test (p < .0001). Motivation and the type of program implemented were identified as particular reasons for positive outcomes. It was concluded that participation in regular physical activity may be beneficial for Down syndrome subjects, particularly because poor fitness levels have been closely associated with health risks such as cardiovascular disease.

AbstractTo track blood pressure (BP) and resting heart rate (RHR) in children and adolescents is important due to its associations with cardiovascular outcomes in the adulthood. Therefore, the aim of this study was to examine BP and RHR over a decade among children and adolescents living in Germany using national examination data. Cross-sectional data from 3- to 17-year-old national survey participants (KiGGS 2003–06, n = 14,701; KiGGS 2014–17, n = 3509) including standardized oscillometric BP and RHR were used for age- and sex-standardized analysis. Measurement protocols were identical with the exception of the cuff selection rule, which was accounted for in the analyses. Different BP and RHR trends were observed according to age-groups. In 3- to 6-year-olds adjusted mean SBP and DBP were significantly higher in 2014–2017 compared to 2003–2006 (+2.4 and +1.9 mm Hg, respectively), while RHR was statistically significantly lower by −3.8 bpm. No significant changes in BP or in RHR were observed in 7- to 10-year-olds over time. In 11- to 13-year-olds as well as in 14- to 17-year-olds lower BP has been observed (SBP −2.4 and −3.2 mm Hg, respectively, and DBP −1.8 and −1.7 mm Hg), while RHR was significantly higher (+2.7 and +3.7 bpm). BP trends did not parallel RHR trends. The downward BP trend in adolescents seemed to follow decreasing adult BP trends in middle and high-income countries. The increase in BP in younger children needs confirmation from other studies as well as further investigation. In school-aged children and adolescents, the increased RHR trend may indicate decreased physical fitness.

AbstractLong-chain n-3 PUFA from fish have been associated with lower risk of CVD. Fish may also contain methylmercury, which may attenuate the inverse associations of the long-chain n-3 PUFA. However, the mechanisms underlying these associations are not fully known. We evaluated the associations of the serum long-chain n-3 PUFA (EPA, DPA and DHA) and hair Hg with resting heart rate (HR), peak HR during cycle ergometer exercise and HR recovery after exercise. A total of 1008 men from the population-based Kuopio Ischaemic Heart Disease Risk Factor Study, aged 42–60 years and free of CVD, were studied. After multivariate-adjustments in ANCOVA, higher serum total long-chain n-3 PUFA concentration was associated with lower resting HR (extreme-quartile difference 2·2 beats/min; 95 % CI 0·2, 4·1, Ptrend across quartiles=0·02), but not with peak HR or HR recovery. Associations were generally similar when EPA, DPA and DHA were evaluated individually, except for DPA, which was also associated with better HR recovery after exercise (extreme-quartile difference 2·1 beats/min; 95 % CI 0·1, 4·2, Ptrend=0·06). Higher hair Hg content had a trend towards lower peak HR after adjusting for the long-chain n-3 PUFA (Ptrend=0·05), but it only slightly attenuated the associations of the serum long-chain n-3 PUFA with HR. These findings suggest that higher serum long-chain n-3 PUFA concentrations are associated with lower resting HR in middle-aged men from Eastern Finland, which may partially explain the potential cardioprotective effect of fish intake.

AbstractThe effects of 16 weeks at sea upon selected parameters of health and physical fitness were investigated in 30 male volunteers (from a total crew of 48 men) prior to, and immediately following deployment. The 30 subjects were assigned toeither an exercise group, ‘Ex’ (n=12), or a non-exercising group, ‘Nil ex ’ (n = 18), according to their reported participation in vigorous training or sports. Body mass index (BMI), calculated from height and weight, revealed that prior to deployment 13 of the 30 subjects (two in the Ex group) had a BMI over 25 kg.m−2 (i. e. overweight), and a further three subjects (all ‘non-exercisers’) had values of 30 kg.m−2 or more (obese). In addition, the diastolic blood pressure of two subjects was in excess of 95 mmHg and five subjects had resting heart rates above 89 beats per minute. Retrospective comparisons between the Ex and Nilex groups revealed a significantly lower percentage body fat (P<0.01) and a faster rate of cardiac recovery (P<0.05) following a standardised bout of exercise in the Ex group, albeit that these individuals were significantly younger (mean age of 24 years) than those in the Nilex group (32 years). Following deployment, in the Nilex group, comparisonof pre- and post values showed that resting heart rate was elevated (P<0.01) on return from sea. Similarly, in the Nilex group heart rate while performing the standardised exercise about was also elevated (P<0.05) on the second test occasion. In the Ex group, heart rate measures during and foJlowing exercise indicated a significantly slower rate of recovery (P<0.05) on the second test occasion.
