The aims of the present study are twofold: 1) to investigate whether heart rate recovery (HRR) after a cycle ergometry test is affected by exercise training and 2) to test the ability of HRR to replicate the baroreflex sensitivity (BRS) changes that occur in response to an exercise training program in coronary artery patients. We randomized 82 coronary artery patients undergoing a residential cardiac rehabilitation program to an exercise training group (TR; n = 43) and an untrained group (UTR; n = 39). All of the patients underwent an exercise test before and after the rehabilitation program. HRR was recorded at the end of the 1st and 2nd min after exercise. BRS was determined at rest before and after treatment. HRR after the 2nd min was significantly improved in TR patients (−21.4 ± 0.9 beats/min) compared with UTR patients (−17.8 ± 1.2 beats/min) at the end of the training program. Improvement in HRR paralleled that in BRS in TR patients (from 3.2 ± 0.3 to 5.3 ± 0.8 ms/mmHg; P < 0.001), whereas no significant change was evident in UTR patients (from 3.5 ± 0 to 4.0 ± 0.4 ms/mmHg; P = 0.230). Our data show that HRR in the 2nd min after the cessation of a cycle ergometer exercise test increased in coronary artery patients after an exercise training period. This result confirms the positive effect induced by exercise training on HRR and extends the conclusions of previous studies to different modalities of exercise (i.e., cycle ergometer). HRR might provide an additional simple marker of the effectiveness of physical training programs in cardiac patients.

AbstractLong-chain n-3 PUFA from fish have been associated with lower risk of CVD. Fish may also contain methylmercury, which may attenuate the inverse associations of the long-chain n-3 PUFA. However, the mechanisms underlying these associations are not fully known. We evaluated the associations of the serum long-chain n-3 PUFA (EPA, DPA and DHA) and hair Hg with resting heart rate (HR), peak HR during cycle ergometer exercise and HR recovery after exercise. A total of 1008 men from the population-based Kuopio Ischaemic Heart Disease Risk Factor Study, aged 42–60 years and free of CVD, were studied. After multivariate-adjustments in ANCOVA, higher serum total long-chain n-3 PUFA concentration was associated with lower resting HR (extreme-quartile difference 2·2 beats/min; 95 % CI 0·2, 4·1, Ptrend across quartiles=0·02), but not with peak HR or HR recovery. Associations were generally similar when EPA, DPA and DHA were evaluated individually, except for DPA, which was also associated with better HR recovery after exercise (extreme-quartile difference 2·1 beats/min; 95 % CI 0·1, 4·2, Ptrend=0·06). Higher hair Hg content had a trend towards lower peak HR after adjusting for the long-chain n-3 PUFA (Ptrend=0·05), but it only slightly attenuated the associations of the serum long-chain n-3 PUFA with HR. These findings suggest that higher serum long-chain n-3 PUFA concentrations are associated with lower resting HR in middle-aged men from Eastern Finland, which may partially explain the potential cardioprotective effect of fish intake.

Sociodemographic Profile

Objective: The study aimed to evaluate heart rate recovery in subjects with restrictive lung disease (RLD) and healthy age matched subjects before and after a rehabilitation program (RP). Methods: This is a cross-sectional study on subjects of both genders, with over 40 years old with and without any diagnosis of restrictive lung disease and who were able to perform physical tasks were included in the study. They were evaluated for sociodemographic profile, lifestyle (ILP), Framingham score, physical capacity (6MWT and treadmill incremental testing) and heart rate recovery before and after RP. Results: 65 subjects were assigned into either G1 (patients with RLD, n=26) or G2 (healthy subjects, n= 39). Initially, patients with RLD increased their heart rate (HR) from 79 to 120bpm, and after the recovery post-exercise, the first minute they reduced HR by nine beats. In the fifth minute after the exercise, HR returned to baseline values. After the RP, mean HR was 71bpm and 79bpm in G1 and G2, respectively. Increased mean 6MWT peak HR in both the groups was seen (110bpm and 120bpm, G1 and G2, respectively). In the first minute of resting, mean HR decreased to 86bpm (- 24bpm) and 72 (-48bpm) in G1 and G2, respectively. In the fifth minute after exercise, HR recovery in both the groups was complete. Conclusion: The RP was effective in improving the first-minute heart rate recovery in patients with restrictive lung disease and, there was an inverse correlation of heart rate recovery with disease severity.

Before And After

Heart rate recovery (HRR), which is defined as the rate of heart rate decline after cessation of exercise, is an important indicator of exercise tolerance. The aim of this study was to investigate the effect of a 4-month moderate reduction in physical activity on pre-exercise and exercise heart rate (HR) as well as HRR after exercise cessation in perimenopausal and postmenopausal women. 10 physically active females, 62.5±3.0 years old, participated in this study. They performed an 8-min constant power output (~50W) cycling exercise at an intensity corresponding to about 65% of maximal heart rate. Heart rate was measured continuously starting from 1 minute before exercise, during the exercise test and 3 min after exercise cessation. Furthermore, before and after exercise, blood pressure (BP) and tympanic temperature (Tt) were measured. The exercise test was performed twice, before and after a 4-month reduction in physical activity. 4 months of the slight reduction in physical activity (by ~16%) did not cause any changes in pre-exercise and exercise HR, however, significantly higher HR during the 1st min after exercise (p=0.03), as well slower HRR (p=0.03), were reported. No effects of the reduction in physical activity were observed in resting and post-exercise BP and Tt. Even a slight reduction in physical activity is accompanied by a lower rate of HRR , which indicates a decrease in exercise tolerance. These results indicate that HRR is a sensitive indicator of physical capacity also in peri- and postmenopausal women, since the changes in HRR in response to physical activity level occur earlier than changes in pre-exercise and exercise heart rate. heart rate, heart rate recovery, physical activity in the elderly

This study aimed to investigate whether the exercise-based amputee rehabilitation program improves postural control and quality of life in people with unilateral transtibial amputation (TTA). Twenty middle-aged men (48.4±3.8 y) with lower limb amputation, in a randomized-controlled longitudinal design, volunteered to participate in the study and were divided into experimental (EXP, n=10) and control (CON, n=10) groups. Before and after 8 weeks of the exercise training program, postural control performance, using one-leg standing (OLS) and Y-balance tests, was measured. The quality of life was also assessed before and after 8 weeks training period using standard questionnaires. Group x time interactions were observed for the EXP group in OLS and Y-balance tests and quality of life scores in comparison to pre- training values and the CON group (p<0.05). People with unilateral TTA who received exercise-based amputee rehabilitation program demonstrated significant improvement in balance performance with significant effects on quality of life.

Before And After

Thermoregulatory responses in the heat (ambient temperature 49 degrees C, 20% relative humidity, 1 m/s wind) were investigated in 10 unacclimated men during 50 min of cycle ergometer exercise (approximately 53% of maximal aerobic power) after a 10-min rest before as well as 24 h and 1 wk after twice the minimal erythemal dose of UV-B radiation that covered approximately 85% of the body surface area. In 7 subjects esophageal temperature (Tes) was recorded while in all 10 subjects five-site skin and rectal temperatures, heart rate, and back, left forearm, and shielded (12 cm2 area) right forearm sweating rates (msw) were recorded at 15-s intervals. Venous blood was collected before and after exercise-heat stress. Mean skin temperature, Tes, rectal temperature, heart rate, and total body sweating rate were not significantly (P greater than 0.05) affected by sunburn. Pre- and postexercise values of hematocrit, hemoglobin, plasma protein, plasma volume, and plasma osmolality were also not affected (P greater than 0.05) by sunburn. Analysis of presunburn and post-sunburn data showed that the Tes intercept for sweating (degrees C) was unaffected (P greater than 0.05), but msw/Tes and final msw from the left forearm (msw/Tes 0.24 +/- 0.02 vs. 0.17 +/- 0.01 mg.cm-2.min-1. degrees C-1, P less than 0.05; msw 0.60 +/- 0.05 vs. 0.37 +/- 0.02, mg.cm-2.min-1, P less than 0.05) and back (msw/Tes 0.43 +/- 0.03 vs. 0.36 +/- 0.01 mg.cm-2.min-1. degrees C-1, P = 0.052; msw 1.08 +/- 0.09 vs. 0.74 +/- 0.05 mg.cm-2.min-1, P less than 0.05) were significantly reduced 24 h postsunburn.(ABSTRACT TRUNCATED AT 250 WORDS)
