Abstract: Background: Tissue Doppler Echocardiography
(TDE) assesses diastolic function more accurately than routine pulse
Doppler echo. Assessment of the effects of dynamic and static
exercises on the heart by using TDE can provides new information
about the athlete-s heart syndrome. Methods: This study was
conducted on 20 elite wrestlers, 14 endurance runners at national
level and 21 non-athletes as the control group. Participants underwent
two-dimensional echocardiography, standard Doppler and TDE.
Results: Wrestlers had the highest left ventricular mass index, enddiastolic
inter-ventricular septum thickness and left ventricular
Posterior wall thickness. Runners had the highest Left ventricular
end-diastolic volume, LV ejection fraction, stroke volume and
cardiac output. In TDE, the early diastolic velocity of mitral annulus
to the late diastolic velocity ratio in athletic groups was greater than
the controls with no significant difference. Conclusion: In spite of
cardiac morphological changes in athletes, TDE shows that cardiac
diastolic function won-t be adversely affected.
Abstract: Recently, the health of retired National Football
League players, particularly lineman has been investigated. A number of studies have reported increased cardiometabolic risk, premature ardiovascular disease and incidence of type 2 diabetes. Rugby union players have somatotypes very similar
to National Football league players which suggest that rugby players may have similar health risks. The International Golden Oldies World Rugby Festival (GORF) provided a
unique opportunity to investigate the demographics of veteran rugby players. METHODOLOGIES: A cross-sectional, observational study was completed using an online web-based
questionnaire that consisted of medical history and
physiological measures. Data analysis was completed using a one sample t-test (50yrs) and Chi-square test. RESULTS: A total of 216 veteran rugby competitors
(response rate = 6.8%) representing 10 countries, aged 35-72 yrs (mean 51.2, S.D. ±8.0), participated in the online survey. As a group, the incidence of current smokers was low at 8.8%
(avg 72.4 cigs/wk) whilst the percentage consuming alcohol
was high (93.1% (avg 11.2 drinks/wk). Competitors reported
the following top six chronic diseases/disorders; hypertension
(18.6%), arthritis (OA/RA, 11.5%), asthma (9.3%),
hyperlipidemia (8.2%), diabetes (all types, 7.5%) and gout (6%), there were significant differences between groups with
regard to cancer (all types) and migraines. When compared to
the Australian general population (Australian Bureau of Statistics data, n=18,000), GORF competitors had a

Abstract: Introduction: Obesity is a major health risk issue in
the present day of life for one and all globally. Obesity is one of the
major concerns for public health according to recent increasing trends
in obesity-related diseases such as Type 2 diabetes. ( Kazuya,
1994).and hyperlipidemia, (Sakata,1990) .which are more prevalent
in Japanese adults with body mass index (BMI) values Z25 kg/m2.(
Japanese Ministry of Health and Welfare,1997). The purpose of the
study was to assess the effect of twelve weeks of brisk walking on
blood pressure and body mass index, anthropometric measurements
of obese males. Method: Thirty obese (BMI= above 30) males, aged
18 to 22 years, were selected from King Fahd University of
Petroleum & Minerals, Saudi Arabia. The subject-s height (cm) was
measured using a stadiometer and body mass (kg) was measured with
a electronic weighing machine. BMI was subsequently calculated
(kg/m2). The blood pressure was measured with standardized
sphygmomanometer in mm of Hg. All the measurements were taken
twice before and twice after the experimental period. The pre and
post anthropometric measurements of waist and hip circumference
were measured with the steel tape in cm. The subjects underwent
walking schedule two times in a week for 12 weeks. The 45 minute
sessions of brisk walking were undertaken at an average intensity of
65% to 85% of maximum HR (HRmax; calculated as 220-age).
Results & Discussion: Statistical findings revealed significant
changes from pre test to post test in case of both systolic blood
pressure and diastolic blood pressure in the walking group. Results
also showed significant decrease in their body mass index and
anthropometric measurements i.e. (waist & hip circumference).
Conclusion: It was concluded that twelve weeks brisk walking is
beneficial for lowering of blood pressure, body mass index, and
anthropometric circumference of obese males.
