Intraarterial blood pressure (BP) response to bench press weight lifting (WL) was evaluated in 11 children. Aortic systolic and diastolic pressures and heart rate (HR) were measured during WL. Baseline systolic and diastolic pressures were 120 and 81 mmHg, and HR was 86 bpm. Subjects lifted to voluntary fatigue weights equaling 60, 75, 90, and 100% of their predetermined one-repetition maximum (1RM). For each weight lifting condition, BP and HR increased as more repetitions were completed. Peak systolic pressure was 168, 177, 166, and 162 mmHg, peak diastolic pressure was 125, 139, 133, and 130 mmHg, and peak heart rate was 142, 148, 142, and 139 bpm at 60, 75, 90, and 100% 1RM, respectively. Peak BP and HR were greater during WL than rest but did not differ between conditions. The relative BP response to WL in children was similar to adult values. For all conditions, pressures increased as more repetitions were completed. It was concluded that peak pressures occur at voluntary fatigue, independent of the combination of resistance and repetitions used to achieve fatigue.

Weekly Alcohol Consumption

1. The association between alcohol consumption and blood pressure was studied in 491 Government employees. The men, aged 21–45 years, volunteered to complete a health questionnaire and submitted to standardized measurements of blood pressure, heart rate and body size. 2. Average weekly alcohol consumption correlated with systolic pressure (r = 0.18, P < 0.001) but not with diastolic pressure. Systolic pressure increased progressively with increasing alcohol consumption with no obvious threshold effect. The effect of alcohol was independent of age, obesity (Quetelet's index) or cigarette smoking. 3. Results indicate that alcohol ranks close to obesity as a preventable cause of essential hypertension in the community.

ABSTRACT Introduction: Basketball can enhance the physical fitness of young people, promote the growth and development of their bodies, and improve health and athletic ability. Objective: To explore the characteristics of basketball players’ cardiac response to increasing load training. Methods: By analyzing 12 juvenile male amateur basketball training athletes, when performing incremental load exercises on the treadmill, using a 12-lead electrocardiograph to record the electrocardiogram, HR, and blood pressure responses for each level of exercise. Results: The mean heart rate of the basketball players before movement was 82.45± 11.44 bpm, slightly higher than the heart rate at rest. Depending on the exercise load, the blood pressure should increase by 5 to 12 mmHg. Under different load training conditions, each level of blood pressure in the Bruce treadmill test procedure should increase 12.5 ~ 44mmHg. The basketball player’s systolic pressure increased by 2.25 ~ 15.7mmHg, diastolic pressure increased by 0.43 to 11.37 mmHg. Conclusions: In basketball players, the psychological stress is less than that of the average person performing the same exercise. The strong ability to adapt to exercise under incremental load training, the contractility of the ventricular muscles and the development of the heart are good.

White Leghorn Chicken

In order to establish the age and manner in which the sex difference in blood pressure of the adult white leghorn chicken develops, periodical blood pressure measurements were made on chicks between 3 and 34 weeks of age. There were no consistent differences in pressure between the sexes under 8 weeks of age. Between the 8th and 13th weeks, pressures began to diverge, and within 4–8 weeks a 26–30-mm sex difference in systolic pressure developed. Significant divergences occurred also in diastolic and pulse pressure. The sex divergence was due primarily to a rise in male pressure, the female level remaining comparatively stable. Net changes in male parameters during the period of rapid development of the sex difference in pressure were: body weight + 219 gm, systolic pressure + 26 mm, diastolic pressure + 16 mm and heart rate –22/ min. The age at which the sex difference in pressure begins and its rate of development appear to be related to sexual maturation in the male. However, no significant correlation between the rising male pressure and testes or comb size could be shown. Normal chick blood pressure values prior to the sex divergence differ within strains of white leghorns and for the two groups used here, between 7 and 9 weeks of age, were 150/130 and 162/136 mm Hg.

Introduction Music has been proposed as a safe, inexpensive, nonpharmacological antistress intervention. The purpose of this study was to determine whether patients undergoing cataract surgery while listening to meditation music experience lower levels of blood pressure and heart rate. Methods Two hundred individuals undergoing cataract surgery participated in the study. Hundred individuals listened to meditation music, through headphones, before and during the operation (intervention group) and 100 individuals received standard care (control group). Patients stress coping skills were measured by the Sense of Coherence Scale (SOC Scale). Systolic and diastolic blood pressure and heart rate were defined as outcome measures. Results According to the SOC Scale, both groups had similar stress coping skills (mean score: 127.6 for the intervention group and 127.3 for the control group). Before entering the operating room (OR) as well as during surgery the rise in systolic and diastolic pressures was significantly lower in the intervention group ( P < 0.001). Among patients receiving antihypertensive therapy, those in the intervention group presented a lower increase only in systolic pressure ( P < 0.001) at both time recordings. For those patients in the intervention group who did not receive antihypertensive treatment, lower systolic blood pressure at both time recordings was recorded ( P < 0.001) while lower diastolic pressure was observed only during entry to the OR ( P = 0.021). Heart rate was not altered between the two groups in any of the recordings. Conclusions Meditation music influenced patients' preoperative stress with regard to systolic blood pressure. This kind of music can be used as an alternative or complementary method for blood pressure stabilizing in patients undergoing cataract surgery.

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 maximum (4/90%), b) 8 repetitions at 80% of one repetition maximum (8/80%), and c) 15 repetitions at 65% of one repetition maximum (15/65%). Immediately following each protocol, measures of heart rate, systolic and diastolic blood pressure were performed, and were used to calculate the rate pressure product. Results: The 4/90% protocol resulted in an increase in heart rate (Δ = 84.57%; effect size [ES] = 0.31), systolic blood pressure (Δ = 24.03%; ES = 0.42), diastolic blood pressure (Δ = 8.47%; ES = 0.27) and rate pressure product (Δ = 129.65%; ES = 0.54). The 8/80% protocol resulted in changes on: heart rate (Δ = 74.94%; ES = 0.57), systolic blood pressure (Δ = 20.67%; ES = 0.27), diastolic blood pressure (Δ = 6.91%; ES = 0.15) and rate pressure product (Δ = 111.78%; ES = 0.48). The 15/65% protocol resulted in alterations on: heart rate (Δ = 66.77%; ES = 0.39), systolic blood pressure (Δ = 16.85%; ES = 0.35), diastolic blood pressure (Δ = 3.38%; ES = 0.13) and rate pressure product (Δ = 96.41%; ES = 0.30). Increases in all variables pre to post resistance exercise were observed for all protocols (p < 0.05). When comparing the three different protocols, it was found that the heart rate (p < 0.001), systolic blood pressure (p = 0.034) and rate pressure product (p < 0.001), were more elevated in the 4/90% compared to the 15/65%. Conclusion: The bench press exercise performed with low volume and high intensity promotes a more pronounced cardiovascular response compared to the same exercise performed with high volume and low intensity.

Abstract Objectives Histidine is an essential amino acid found in the diet through protein-rich foods. Previous research demonstrated benefits of histidine due to anti-inflammatory, anti-oxidant, and glucoregulatory properties. To date, histidine requirement for adults has not be established; current expert opinion for histidine is 8 and 12 mg/(kg body weight × day), an estimate that was extrapolated from the infant requirement for histidine. Further, the clinical safety of histidine supplementation above the average dietary intake has not been determined. Objective: To determine the safety of graded-doses of histidine in a healthy adult population. Methods Our preliminary study includes 30 adults (n = 12 males and n = 18 females, aged 21–50 y). Following the completion and review of a health history questionnaire, vitals, and a biochemical panel, participants were deemed healthy and able to participate. After baseline measures were obtained, participants consumed encapsulated histidine pills daily for four weeks followed by a three-week washout period between each dose. Participants consumed one of three doses (4 g, 8 g, and 12 g) of histidine during each of the four-week supplement periods. A complete biochemical panel was run at baseline, week 2 and 4 of supplement, as well as washout. Anthropometric, body composition, sleep patterns, dietary intake, and urine samples were also collected throughout the study (analyses underway). Results Baseline descriptive statistics are as follows for females [males]: body weight 65 ± 0.55 kg [62.91 ± 3.17 kg], systolic pressure 113 ± .54 mmHg [125 ± 2.93 mmHg], diastolic pressure 70 ±.48 mmHg [74 ± 3.22 mmHg], and heart rate 74 ± 0.56 bpm [63 ±3.17 bpm]. There were no observed differences between baseline and measurements taken at any of the three doses for body weight, systolic blood pressure, diastolic blood pressure, and heart rate. There was no effect of histidine dose on the biochemical measures of aspartarte amino transferase (U/L, P = 0.096), alanine amino transferase (U/L, P = 0.47), creatinine (mg/dL, P = 0.79), glucose (mg/dL, P = 0.06), insulin (μIU/ml, P = 0.48), or c-reactive protein (mg/L, P = 0.19). Conclusions In our current analyses, we observe no deleterious effects of taking up to 12 grams of histidine in healthy young adults. Funding Sources International Council on Amino Acid Science.

Response To Exercise

Cardiac output (Q), heart rate (HR), blood pressure, and oxygen consumption (VO2) were measured repeatedly both at rest and at two levels of exercise in six subjects during microgravity exposure. Exercise was at 30 and 60% of the workload producing the individual's maximal VO2 in 1 G. Three of the subjects were on a 9-day flight, Spacelab Life Sciences-1, and three were on a 15-day flight, Spacelab Life Sciences-2. We found no temporal differences during the flights. Thus we have combined all microgravity measurements to compare in-flight values with erect or supine control values. At rest, Q in flight was 126% of Q erect (P < 0.01) but was not different from Q supine, and HR in flight was 81% of HR erect (P < 0.01) and 91% of HR supine (P < 0.05). Thus resting stroke volume (SV) in flight was 155% of SV erect (P < 0.01) and 109% SV supine (P < 0.05). Resting mean arterial blood pressure and diastolic pressure were lower in flight than erect (P < 0.05). Exercise values were considered as functions of VO2. The increase in Q with VO2 in flight was less than that at 1 G (slope 3.5 vs. 6.1 x min-1.l-1.min-1). SV in flight fell with increasing VO2, whereas SV erect rose and SV supine remained constant. The blood pressure response to exercise was not different in flight from erect or supine. We conclude that true microgravity causes a cardiovascular response different from that seen during any of its putative simulations.

The purpose of this study was to record the blood pressure response to heavy weight-lifting exercise in five experienced body builders. Blood pressure was directly recorded by means of a capacitance transducer connected to a catheter in the brachial artery. Intrathoracic pressure with the Valsalva maneuver was recorded as mouth pressure by having the subject maintain an open glottis while expiring against a column of Hg during the lifts. Exercises included single-arm curls, overhead presses, and both double- and single-leg presses performed to failure at 80, 90, 95, and 100% of maximum. Systolic and diastolic blood pressures rose rapidly to extremely high values during the concentric contraction phase for each lift and declined with the eccentric contraction. The greatest peak pressures occurred during the double-leg press where the mean value for the group was 320/250 mmHg, with pressures in one subject exceeding 480/350 mmHg. Peak pressures with the single-arm curl exercise reached a mean group value of 255/190 mmHg when repetitions were continued to failure. Mouth pressures of 30–50 Torr during a single maximum lift, or as subjects approached failure with a submaximal weight, indicate that a portion of the observed increase in blood pressure was caused by a Valsalva maneuver. It was concluded that when healthy young subjects perform weight-lifting exercises the mechanical compression of blood vessels combines with a potent pressor response and a Valsalva response to produce extreme elevations in blood pressure. Pressures are extreme even when exercise is performed with a relatively small muscle mass.

Six young men weight trained 3 days∙week−1 for 19 weeks, on each day doing 3 warm-up sets of 20 repetitions followed by 1 set each at 15-20, 10-15, and 7-10 RM (Day 1), 3 sets at 15-20 RM (Day 2), and 1 set at 15-20 and 2 sets at 10-15 RM (Day 3) of a seated bilateral leg press exercise. Training increased (P < 0.05) the maximal single leg press lift (1-RM, 26%) and knee extensor cross-sectional area (12%). Arterial (brachial artery catheter) and esophageal (probe) pressure responses were measured before and after training as subjects did sets of as many repetitions as possible up to 20 reps with 50, 70, 80, 85, and 87.5% 1-RM. After training, peak values of systolic pressure attained during a set (M pre/post, mm Hg) were significantly (P < 0.05) increased at 85% (325/360,10.8%) 1-RM. Peak diastolic pressure increased significantly at 50 (136/151, 11.0%), 70 (185/200, 8.1%), and 80% (215/234, 8.8%). Peak esophageal pressure increased significantly at 80% (71/91, 28.2%) 1-RM. For a given absolute weight lifted, all responses were markedly reduced after training. It is concluded that weight training can (a) increase the peak arterial and esophageal pressure responses attained during maximal weight lifting exercise, and (b) reduce the arterial and esophageal pressure responses to lifting the same absolute weight. Key words: weight training, systolic pressure, diastolic pressure, esophageal pressure, Valsalva maneuver
