a periodic increase in blood pressure (bp) occurs during apneic episodes in patients with obstructive sleep apnea (osa). several factors including hypoxemia and an increase in heart rate (hr) were reported to be responsible for this increased bp. to examine the contribution of these two factors in increasing bp, 35 healthy male subjects (mean age±sd= 23.64±3.80) were studied in three experiment...

objective: for many years in herbal medicine the antihypertensive and lowering blood lipid properties of achillea wilhelmsii (a. wilhelmsii) have been suggested. in the present study the impacts of the plant extract on rabbit’s blood pressure and heart rate have been investigated. materials and methods: twelve nwz rabbits weighed 2-3 kg were randomly divided into two groups of 6 rabbits. the te...

We planned to undertake a comparative study of the effect of short term (three weeks) training in savitri (slow breathing) and bhastrika (fast breathing) pranayams on respiratory pressures and endurance, reaction time, blood pressure, heart rate, rate-pressure product and double product. Thirty student volunteers were divided into two groups of fifteen each. Group I was given training in savitr...

Objective: To determine and compare the cardiovascular responses to three resistance exercise protocols with different volumes and loads. Methods: The study included 15 healthy subjects, experienced in resistance training, who underwent supine bench press exercise with three different volumes and loads separated by 48 hours, with a crossover model: a) 4 repetitions at 90% of one repetition maxi...

Abstract Objectives To determine the correlation between anthropometric indices and selected hemodynamic parameters among secondary adolescents aged 12–17 years. Results Our findings showed weak positive generally body surface area, neck circumference conicity index with (systolic blood pressure, diastolic resting pulse rate, mean arterial rate pressure product pressure). However, ponderosity i...

Measurements were made of heart rate, aortic blood pressure, systolic ejection period/beat, myocardial blood flow, and myocardial oxygen consumption in nine normal young men during three bouts of upright bicycle exercise: 1) at the workload which produced a heart rate of 120 beats/minute, 2) at the higher workload necessary to produce a heart rate of 120 beats/minute after administration of int...
