The effect of exercise on large artery haemodynamics in healthy young men

Background Brachial blood pressure predicts cardiovascular outcome at rest and during exercise. However, because of pulse pressure amplification, there is a marked difference between brachial pressure and central (aortic) pressure. Although central pressure is likely to have greater clinical importance, very little data exist regarding the central haemodynamic response to exercise. The aim of the present study was to determine the central and peripheral haemodynamic response to incremental aerobic exercise. Materials and methods Twelve healthy men aged 31 +/- 1 years (mean +/- SEM) exercised at 50%, 60%, 70% and 80% of their maximal heart rate (HRmax) on a bicycle ergometer. Central blood pressure and estimated aortic pulse wave velocity, assessed by timing of the reflected wave (T-R), were obtained noninvasively using pulse wave analysis. Pulse pressure amplification was defined as the ratio of peripheral to central pulse pressure and, to assess the influence of wave reflection on amplification, the ratio of peripheral pulse pressure to nonaugmented central pulse pressure (PPP : CDBP-P-1) was also calculated. Results During exercise, there was a significant, intensity-related, increase in mean arterial pressure and heart rate (P < 0.001). There was also a significant increase in pulse pressure amplification and in PPP : CDBP-P-1 (P < 0.001), but both were independent of exercise intensity. Estimated aortic pulse wave velocity increased during exercise (P < 0.001), indicating increased aortic stiffness. There was also a positive association between aortic pulse wave velocity and mean arterial pressure (r = 0.54; P < 0.001). Conclusions Exercise significantly increases pulse pressure amplification and estimated aortic stiffness.

Semen profiles of young men involved as bicycle taxi cyclists in Mangochi District, Malawi: A case-control study

Aim The purpose of this study was to evaluate the semen profiles of bicycle taxi cyclists and healthy controls in Mangochi district, Malawi. Methods Semen samples were collected from young bicycle taxi cyclists after two to three days of sexual abstinence. A control group, comprising young men who were not bicycle taxi operators also submitted semen samples. Samples were left to liquefy for 30 minutes before measurements were conducted of volume, concentration, total motility, and progressive motility. This was followed by preparation of morphology slides. Light microscopy was used for sperm analysis. Results Semen parameters such as volume (1.66 ± 0.18 mL vs. 3.64 ± 0.17 mL; p = 0.0001), concentration (28.31 ± 4.33 x 106/mL vs. 54.95 ± 5.93 x 106/ mL; p = 0.02) , total motility (56.98% ± 8.22% vs. 56.98% ± 8.22%; p = 0.03), progressive motility (22.57% ± 3.35% vs. 59.69% ± 4.82%; p = 0.004), and morphology (6.98% ± 3.23% vs. 19.73% ± 2.32%; p = 0.006) were significantly reduced in the bicycle taxi cyclists compared to the healthy controls. Conclusion In this case-control study, bicycle taxi operators had lower semen volume, concentration, total motility, and progressive motility, as well as a higher concentration of abnormally shaped spermatocytes, compared to healthy controls.

School success stories of young men at risk

This paper arises from the concern about school inequality. This is a topic that uses to concern European organizations. Education is one of the five key goals of the “European Strategy 2020” to achieve economic growth, to combat social inequality and build a socially and economically strong Europe. This concern is also shared by international organisations such as the OECD, the World Bank and the UNESCO which, together with the European Union have become political agents that exercise their influence on national policies.

Driver sleepiness—Comparisons between young and older men during a monotonous afternoon simulated drive

Young men figure prominently in sleep-related road crashes. Non-driving studies show them to be particularly vulnerable to sleep loss, compared with older men. We assessed the effect of a normal night's sleep vs. prior sleep restricted to 5 h, in a counterbalanced design, on prolonged (2 h) afternoon simulated driving in 20 younger (av. 23 y) and 19 older (av. 67 y) healthy men. Driving was monitored for sleepiness related lane deviations, EEGs were recorded continuously and subjective ratings of sleepiness taken every 200 s. Following normal sleep there were no differences between groups for any measure. After sleep restriction younger drivers showed significantly more sleepiness-related deviations and greater 4–11 Hz EEG power, indicative of sleepiness. There was a near significant increase in subjective sleepiness. Correlations between the EEG and subjective measures were highly significant for both groups, indicating good self-insight into increasing sleepiness. We confirm the greater vulnerability of younger drivers to sleep loss under prolonged afternoon driving.
