Diastolic hypertension and declarative knowledge performance. Is there a relation in young people?
No full textRelationships between time of day and variation of blood pressure response to aerobic exercise
No full textAim: Physical exercise is widely used in primary and secondary prevention of hypertension. National and international guidelines recommend type, frequency, intensity, duration and energy expenditure of exercise, but suggest nothing about the time of day for exercise. This study investigated blood pressure response during aerobic exercise and 30 min of recovery according to time of day. Methods: Twenty-eight sedentary male university students (25±2 yrs) underwent a physical fitness examination before entering the study. Subjects took part in 3 training sessions scheduled 1 week apart at 3 different times of day (9.30 AM; 2 PM; and 6.30 PM). Training was performed on a Recumbent Bike. Each session consisted of 10 min of warm-up at 55%HRmax, 35 min at 70%HRmax, 5 min of cool-down, followed by 30 min of recovery while sitting on the bike. Blood pressure and ratings of perceived exertion were measured during training; during recovery, blood pressure only was measured. Results: ANOVA for repeated measures showed a best trend of diastolic blood pressure during training and recovery when exercise was performed at 6.30 PM. Ratings of perceived exertion were higher during the morning session. No differences were noted for in systolic blood pressure trends. Conclusions. Early evening physical exercise seems to optimize its positive effect on the reduction of diastolic blood pressure
Fat mass, fitness and health in undergraduate male university students
No full textAim. Physical exercise prevents and reduces android obesity and its related health diseases, through both weight loss and fitness level improvement. In fact, even in the absence Of weight loss, an high fitness level is associated with a lower waist circumference (WC) for a given BMI. Aim of this study was to compare the cardio-circulatory status of over-weight or moderately obese trained (OT), over-weight or moderately obese sedentary (OS), and normal-weight sedentary (NS) men.
Methods. Resting heart rate (rHR), blood pressure, simple anthropometric parameters, body composition, and fitness level were assessed in 130 male undergraduate University students (21.43+/-2.39) yrs). Information oil physical exercise practice were also collected.
Results. Statistical analysis were performed on 29 NS, 45 OT and 35 OS. Pairwise comparison between groups showed a best rHR in OT compared to NS (P=0.004); blood pressure and fitness level were equal. Comparing OT and OS matched for fat mass, We found that OT had lower rHR (P=0.004) and systolic blood pressure (P=0.004), while fitness level (P=0.003) was higher than OS. OT had lower direct correlation among WC, fat mass and fitness level than OS and NS.
Conclusion. Exercise practice increases health of over-weight or moderately obese men through the reduction of some cardiovascular risk factors
Pratica dell’esercizio fisico, composizione corporea e salute cardiovascolare in giovani universitari
No full textAre physiological characteristics of Caribbean dance useful for health?
No full textAIM:
Although the current literature underlines the main role of physical inactivity in the development of chronic diseases and premature death, 65% of adults do not reach the minimum movement levels required to maintain and improve health. The aim of this study was to investigate whether the metabolic and cardiocirculatory characteristics of a single lesson of Caribbean dance fit with international recommendations to improve health through movement.
METHODS:
Energy expenditure, exercise intensity, mean heart rate and blood pressure response to a 90-minute lesson were analysed in 24 beginner and 24 experienced dancers (mean age 33.93+/-9.98 years).
RESULTS:
MANCOVA was used to analyse energy expenditure and exercise intensity of our sample, stratified for gender and experience. Body weight was inserted as a covariate. Experienced had a major total energy expenditure (372.75+/- 75.32 vs 297.33+/-87.54 kcal; P6 metabolic equivalents (METs) (8.04+/-10.65 vs 1.47+/-2.16; P<0.001), mean METs (3.81+/-0.32 vs 3.42+/-0.37; P<0.05) and mean heart rate (60.68+/-1.35 vs 53.24+/-3.91 %HRR; P<0.001) than beginner dancers. There were no statistical differences in blood pressure values.
CONCLUSIONS:
Caribbean dance fits with international guidelines to improve health and can aid the promotion and enhancement of health through its physiological characteristics, and may reduce drop-out due to a reduced motivation to move
SMARTWATCH, ACTIVITY TRACKER E SALUTE NELLA PERSONA CON DIABETE
Full text linkFor people with diabetes, technological development represents an important opportunity to optimize therapeutic outcomes through an approach aimed at improving the quality of physical activity, exercise, and sleep, while combating sedentary behavior. However, this ap- proach requires adequate training of members of the health care team and includes, in addition to knowledge of the dimensions of the afore- mentioned behavioral variables, an understanding of the dynamics of change associated with them. It is also crucial not to overlook the importance of active patient participation and the selection of appro- priate tools and equipment
Physical exercise for blood pressure management: are intensity and length the only parameters to consider?
No full textAim. The aim of the study was to determine whether five different cardiofitness machines have the same effect on blood pressure and/or cardiac response at exercise matched for length and relative intensity.
Methods. Thirty-five normotensive healthy sedentary men (mean age 25.13 +/- 2.39) worked out on each machine in a 80-min session divided into 10 min warm up at 45% of heart rate reserve (HRR), 35 min at 55-60% of HRR, 5 min cool-down at 45%, of HRR and 10 in in resting recovery in standardized room. Heart rate and electrocardiogram wet e monitored and recorded during each part of the experiment. Blood pressure was measured at baseline, then after 10, 25, 40 and 50 min of exercise, and then at 5, 10, 15 and 30 min during 30 min of sitting rest. Ratings of perceived exert ion (RPE)using I he Borg Scale were scored at baseline, and after 10, 20, 25, 30, 40 and 50 in in of exercise. Exercises were performed on: treadmill runner, cross trainer, recumbent bike, bike and power arm.
Results. The power arm elicited the worst diastolic response during both exercise and recovery; cross trainer the best. RPE was higher at exercise on the power arm than on the other equipment. No differences were found in systolic response and electrocardiograms.
Conclusion. Specific stress testing before starting an exercise program is recommended. The elevated diastolic blood pressure response to exercising with an arm ergometer, may increase the cardiovascular risk in hypertensive Subjects
