Post Exercise Recovery

There is paucity of scientific information on sex differences in heart rate (HR) responses during and after a sub-maximal exercise test in young adults. We assessed sex differences in normal HR responses during and after a sub-maximal-effort cycle ergometer exercise test in apparently healthy young adults. One hundred young adults (50 males and 50 females) participated in the study. Subjects performed a sub-maximal exercise at an intensity that produced 60–85% of a pre-determined age-predicted maximum HR. Measurements of subjects’ HR were done at rest, during exercise and post exercise recovery periods. The present data indicated that after adjusting for covariates, greater (P<0.05) HR responses (delta HR 2 min, delta HR 5 min, delta peak HR) were observed in men relative to women. Males also indicated significantly higher (P<0.05) %HRmax and %HRreserve compared to females. Variables of HR response during post-exercise recovery did not differ between males and females. HR responses during exercise were greater in young adult males compared to females while HR responses at post-exercise recovery were similar between the two groups. The present findings may be useful in interpreting more accurately the significance of HR responses during and after exercise in healthy young adults according to sex.

Deep Water Running

The aim of the study was to examine submaximal and maximal physiological responses and perceived exertion during deep-water running with a vest compared with the responses during treadmill running in healthy elderly women. Eleven healthy women 70 ± 2 years old participated. On two different occasions they performed a graded maximal exercise test on a treadmill on land and a graded maximal exercise test in water wearing a vest. At maximal work the oxygen uptake was 29% lower (p < .05), the heart rate was 8% lower (p < .05), and the ventilation was 16% lower (p < .05) during deep-water running than during treadmill running. During submaximal absolute work the heart rate was higher during deep-water running than during treadmill running for the elderly women. The participants had lower maximal oxygen uptake, heart rate, ventilation, respiratory-exchange ratio, and rate of perceived exertion during maximal deep-water running with a vest than during maximal treadmill running. These responses were, however, higher during submaximal deep-water running than during treadmill running.

Chronic Smoking

Background Smoking is a major cause of cardiovascular disease and mortality. Smoking-related deaths in Greece account for 23%, whereas 41% of young Greeks are smokers, the highest percentage in Europe. The purpose of this study was to examine the effects of chronic smoking on the rate-pressure product and exercise tolerance in young, healthy male smokers. Design and methods Forty-two smokers and 51 nonsmokers were selected from a population of 543 students based on their age, sex, body mass index, physical fitness, smoking habit and health status. All participants were tested with the standard Bruce treadmill protocol. The rate-pressure product was obtained at rest and during exercise at a given submaximal workload. The evaluation of exercise tolerance was based on peak workload achieved and maximal exercise test duration. Results The smokers had a higher rate-pressure product at rest ( P < 0.001) due to their higher resting heart rate ( P < 0.001). Resting values of blood pressure did not differ significantly between the two groups. During exercise, smokers had a greater rate-pressure product ( P < 0.001), mainly due to their significantly higher systolic blood pressure ( P = 0.008). The smokers had a higher submaximal heart rate ( P = 0.005), but the differences in heart rate between groups were reduced for smokers during exercise when compared to rest. The smokers' exercise tolerance was impaired and their maximal exercise test duration time was significantly shorter ( P < 0.001). Conclusions Chronic smoking was found to affect young male smokers' cardiovascular fitness, impairing the economy and decreasing the capacity of their circulatory system.
