ABSTRACT Background: Community-based exercise classes have the potential to sustain the benefits of cardiac rehabilitation for the prevention of future cardiovascular events. Such classes can be designed to address this need; however, whether such classes meet these objectives is rarely evaluated. Methods: Facility managers, instructors, and class participants completed questionnaires. Two assessors observed exercise classes called “Heartmoves.” A maximum of 10 participants per class wore heart rate (HR) monitors. Mean and highest HR as percentage of age-predicted maximum were recorded for class components. At the end of classes, participants completed a 10-point rating of perceived exertion (RPE) scale. Data were compared with international guidelines for community exercise classes for individuals with cardiovascular disease (CVD). Results: Twelve classes were observed with 82 participants. All classes included guideline-recommended components of warm-up, cooldown, strength, and aerobic conditioning; 58% of classes (n = 7) incorporated strength and aerobic conditioning in a circuit. Class participants exercised at low to moderate intensities as indicated by mean ± SD: HR (warm-up 55% ± 11% age-predicted maximum HR; cooldown 52 ± 11; strength 59 ± 11; aerobic conditioning 58 ± 12); and overall RPE (6 ± 2). Class participants' mean age was 70 ± 8 years; 27% (n = 24) were referred by health professionals; 73% (n = 61) attended for fitness; 61% (n = 50) had CVD risk factors; and 21% (n = 17) reported diagnosed CVD. Conclusion: Community exercise classes for individuals with CVD, specifically those aligned with Heartmoves, may comply with international guidelines, although few class participants have diagnosed CVD.

Introduction: Physical activity is presumed to improve cardiovascular disease (CVD), of which carotid artery intima-media thickness (CIMT) is a common indicator. Individuals with spinal cord injury (SCI) have limited mobility and therefore an expected increased risk for CVD. The purpose of this study was to determine which CVD risk factors predict CIMT among women with SCI, with the ultimate goal of targeting therapy to improve CVD in this population. Methods: One hundred twenty-two women with SCI who attended an outpatient SCI clinic and met inclusion and exclusion criteria participated in this study. SCI was categorized into 1 of 4 categories: complete tetraplegia, incomplete tetraplegia, complete paraplegia, and incomplete paraplegia. Maximum heart rate and VO2 max were obtained using bicycle ergometry with ventilatory gas exchange and continuous electrocardiogram. Hierarchical regression was used to predict CIMT, with the first block including demographic variables (age, race, smoking status) and the second block including physiologic variables (total cholesterol, heart rate, VO2 max, BMI, fasting serum glucose, hemoglobin A1c, and blood pressure). Results: Similar findings were observed for left and right CIMT, therefore only results from right CIMT are reported. The overall model was significant, F(16,46)=8.53, p=.000. Adjusted R square was .54 for the first block of variables and increased significantly (p=.006) to .66 when the second block of variables was added. Significant predictors at alpha=.05 included age (beta=.51, t=4.79, p=.000) and max/peak heart rate (beta=−.336, t=−2.39, p=.02). At alpha=.10, A1c was significant (beta=.187, t=1.99, p=.053). Conclusions: Although low aerobic conditioning is a purported CVD risk factor, quantitative measurements of such lack a demonstrable relationship with subclinical atherosclerosis (CIMT), perhaps because of its reduced importance relative to other CVD risk factors in a mobile population. We found expected relationships with CIMT in our SCI population (i.e., age), however we also found a quantitative measure of aerobic conditioning (max/peak heart rate) to be associated with CIMT. Our data indicate that SCI individuals may bear a greater CVD burden from cardiac de-conditioning than the general population and that investigation of a cohort with mobility limitation may provide a unique opportunity to study the impact of physical conditioning on CVD risk.

Context:Warm-up before athletic competition might enhance performance by affecting various physiological parameters. There are few quantitative data available on physiological responses to the warm-up, and the data that have been reported are inconclusive. Similarly, it has been suggested that varying the recovery period after a standardized warm-up might affect subsequent performance.Purpose:To determine the effects of varying post-warm-up recovery time on a subsequent 200-m swimming time trial.Methods:Ten national-caliber swimmers (5 male, 5 female) each swam a 1500-m warm-up and performed a 200-m time trial of their specialty stroke after either 10 or 45 min of passive recovery. Subjects completed 1 time trial in each condition separated by 1 wk in a counterbalanced order. Blood lactate and heart rate were measured immediately after warm-up and 3 min before, immediately after, and 3 min after the time trial. Rating of perceived exertion was measured immediately after the warm-up and time trial.Results:Time-trial performance was significantly improved after 10 min as opposed to 45 min recovery (136.80 ± 20.38 s vs 138.69 ± 20.32 s, P < .05). There were no significant differences between conditions for heart rate and blood lactate after the warm-up. Pre-time-trial heart rate, however, was higher in the 10-min than in the 45-min rest condition (109 ± 14 beats/min vs 94 ± 21 beats/min, P < .05).Conclusions:A post-warm-up recovery time of 10 min rather than 45 min is more beneficial to 200-m swimming time-trial performance.

Abstract Background This study addressed the lack of data on the effect of warm-up (WU) duration in hot-dry climate (~ 30 °C; ~ 18% RH), on thermoregulation, muscular power-output, and fatigue after specific soccer repeated-sprint test (RSA). Methods Eleven amateur soccer players participated in a cross-over randomized study and they underwent the Bangsbo repeated-sprint test, after three WU durations (i.e. WU10, WU15 and WU20 min) at 70% of MAV, and on different days. Peak power (PP), mean power (MP) and the fatigue index (FI) were recorded and analyzed. Likewise, heart rate (HR), tympanic temperature (Ttym), mean body temperature (MBT) and rating of perceived exertion (RPE) were recorded during each session. Results The repeated measure ANOVA showed that MP improved after WU15 in comparison to WU10 and WU20 (p = 0.04 and p = 0.001; respectively). Nonetheless, no significant effect on PP was recorded after all WU durations. FI during RSA increased after WU20 in comparison to WU15 and WU10 (p < 0.001 and p = 0.003; respectively). Higher RPE values (p < 0.001) were recorded after WU15 and WU20 in comparison to WU10 duration. The two-way ANOVA showed higher ΔTtym and ΔMBT values after WU15 and WU20 compared to WU10 (p = 0.039 and p < 0.001for Ttym; p = 0.005 and p < 0.001 for MBT, respectively). Conclusions The WU15 at 70% of MAV better assists mean power-output during soccer RSA in hot-dry (~ 30 °C; 18% RH) climate, but not peak power. Reducing WU duration up to 10 min seems to be insufficient to induce beneficial physiological changes necessary for optimizing repeated-sprint performance, while its extension up to 20 min remains detrimental for muscular power and induces higher fatigue.

This study investigated the effects of preferred and non-preferred warm-up music listening conditions on subsequent exercise performance. A total of 12 physically active male and female participants engaged in a crossover, counterbalanced research design in which they completed exercise trials after 3 different warm-up experiences of (a) no music (NM), (b) preferred music (PREF), and (c) nonpreferred music (NON-PREF). Participants began warming up by rowing at 50% of of age-predicted heart rate maximum (HRmax) for 5 minutes while exposed to the three music conditions. Immediately following the warm-up and cessation of any music, participants completed a 2000-m rowing time trial as fast as possible. Relative power output, trial time, heart rate, rating of perceived exertion, and motivation were analyzed. Results indicated that, compared with NM, relative power output was significantly higher ( p  =   .018), trial time was significantly lower ( p  =   .044), and heart rate was significantly higher ( p  =   .032) during the PREF but not the NON-PREF condition. Rating of perceived exertion was not altered, regardless of music condition ( p > .05). Motivation to exercise was higher during the PREF condition versus the NM ( p  =   .001) and NON-PREF ( p <  .001) conditions. Listening to preferred warm-up music improved subsequent exercise performance compared with no music, while nonpreferred music did not impart ergogenic benefit.

The purpose of this study was to assess the effects of listening to music during warm-up and resistance exercise on physiological (heart rate and blood pressure) and psychophysical (rating of perceived exertion) responses in trained athletes. Twelve strength trained male participants performed warm-up and resistance exercise without music (WU+RE without M), warm-up and resistance exercise with music (WU+RE with M), WU with M and RE without M, and WU without M and RE with M, with 48 hours space between sessions. After completing each session, the rating of perceived exertion (RPE) was measured. Also, heart rate (HR), systolic (SBP) and diastolic blood pressure (DBP), mean arterial pressure (MAP), and rate pressure product (RPP) were assessed before, after, and 15, 30, 45, and 60 min after exercise. Results indicated that RPE was higher for WU+RE without M condition in comparison with other conditions. All conditions showed increases in cardiovascular variables after exercise. The responses of HR, SBP, and RPP were higher for WU+RE without M condition. Thus, using music during warm-up and resistance exercise is a legal method for decreasing RPE and cardiovascular responses due to resistance exercise.

Purpose: To analyze the effects of different warm-up protocols on endurance-cycling performance from an integrative perspective (by assessing perceptual, neuromuscular, physiological, and metabolic variables). Methods: Following a randomized crossover design, 15 male cyclists (35 [9] y; peak oxygen uptake [VO2peak] 66.4 [6.8] mL·kg−1·min−1) performed a 20-minute cycling time trial (TT) preceded by no warm-up, a standard warm-up (10 min at 60% of VO2peak), or a warm-up that was intended to induce potentiation postactivation (PAP warm-up; 5 min at 60% of VO2peak followed by three 10-s all-out sprints). Study outcomes were jumping ability and heart-rate variability (both assessed at baseline and before the TT), TT performance (mean power output), and perceptual (rating of perceived exertion) and physiological (oxygen uptake, muscle oxygenation, heart-rate variability, blood lactate, and thigh skin temperature) responses during and after the TT. Results: Both standard and PAP warm-up (9.7% [4.7%] and 12.9% [6.5%], respectively, P < .001), but not no warm-up (−0.9% [4.8%], P = .074), increased jumping ability and decreased heart-rate variability (−7.9% [14.2%], P = .027; −20.3% [24.7%], P = .006; and −1.7% [10.5%], P = .366). Participants started the TT (minutes 0–3) at a higher power output and oxygen uptake after PAP warm-up compared with the other 2 protocols (P < .05), but no between-conditions differences were found overall for the remainder of outcomes (P > .05). Conclusions: Compared with no warm-up, warming up enhanced jumping performance and sympathetic modulation before the TT, and the inclusion of brief sprints resulted in a higher initial power output during the TT. However, no warm-up benefits were found for overall TT performance or for perceptual or physiological responses during the TT.

Abstract Background: Nigeria’s healthcare system capacity to stem the increasing trend in hypertension is limited in coverage, scope and manpower. Use of trained community-based care providers demonstrated to be an effective complement in improving access to, and supporting healthcare delivery has not been adequately examined for hypertension care in Nigeria. This study is proposed to evaluate the effectiveness of using trained Community-based Oriented Resource Persons (CORPs) to improve hypertension control in Nigeria. Methods: An intervention study will be conducted in three states using mixed method design. First, is a baseline survey using a semi-structured pre-tested questionnaire to collect information on demographics, clinical data, knowledge, occurrence and risk factors of hypertension among 1,704 adults ≥18 years. Focus Group Discussions (FGD) and Key Informant Interviews (KII) will be conducted to explore community’s experience of hypertension, challenges with hypertension management, and support required to improve control in 10 selected communities in each state. The second is a cluster randomized controlled trial to evaluate effect of a package on reduction of blood pressure (BP) and prevention of cardiovascular (CVD) risk factors among 200 hypertensive patients to be followed up in intervention and control arms over a six-month period in each state. The package will include trained CORPs conducting community-based screening of BP and referral, diagnosis confirmation and initial treatment in the health facility, followed by monthly home-based follow-up care and provision of health education on hypertension control and healthy lifestyle enhanced by phone voice message reminders. In the control arm, the usual care (diagnosis, treatment and follow up care in hospital of patient’s choice) will continue. Third, an end-line survey will be conducted in both intervention and control communities to evaluate changes in mean BP, control, knowledge, and proportion of other CVD risk factors. In addition, FGD and KII will be used to assess participants’ perceived quality and acceptability of the interventions as delivered by CORPs.Discussion: This research is expected to create awareness, improve knowledge, perception, behaviours, attitude and practices that will reduce hypertension in Nigeria. Advocacy for buy-in and scale up of using CORPs in hypertension care by the government is key if found to be effective. Trial registration: PACTR Registry- PACTR202107530985857.

Abstract Background: Cardiovascular disease is the leading cause of death worldwide. Notwithstanding the well-known benefits of cardiac rehabilitation (CR), adherence to CR remains low, particularly in women. Aerobic interval training (AIT) has received specific attention as an emerging exercise-training paradigm that addresses frequently cited barriers to CR (i.e. lack of motivation/enjoyment and time, perceiving exercise regime as tiring/boring) and improves cardiovascular risk factors. Previous studies have examined the safety of AIT in CR settings; there is little evidence on the feasibility of AIT in CR. The aims of this study were to evaluate the feasibility of AIT within a CR setting and examine the sex differences regarding the feasibility of such programming. Methods: Patients attended an on-site AIT CR program (10-minute warm-up, 25 minutes of interspersed high [HI - 4 minutes at 85-95% HRpeak] and low [LO - 3 minutes at 60-70% HRpeak] intervals, 10-minute cool-down) twice weekly for 10 weeks. Heart rate (HR) and the Borg rating of perceived exertion (RPE) scale were recorded at each session. Feasibility was assessed by: (1) attendance and compliance: the number of sessions attended and the compliance to the prescribed HI and LO HR ranges; (2) the patient experience: patients’ perceived effort, program difficulty, if the program was challenging and satisfying; and, (3) safety. Descriptive statistics were used to report the means and their variations. Mann-Whitney U tests and Chi-square analyses were performed to examine sex-differences. Results: A total of 160 patients (33% women, 67% men, 57.2 ± 9.6 years) attended the AIT program and completed 16±5 classes with a low attrition rate (11.3%). Most patients met or exceeded the prescribed target HR for the HI (80%) and LO (84%) intervals, respectively. Patients reported a “somewhat hard” RPE for HI (14±1) and “very light” for LO (10±2) intervals. All patients were satisfied with the program and found it challenging. Most patients found AIT to be difficult (7±2), yet safe (97%). Three vasovagal episodes occurred and more women dropped-out of the program than men (p<0.01). Conclusions: AIT is a feasible, safe and well-received exercise paradigm in a CR setting.

This randomized crossover counterbalanced study investigated, in recreational runners, the acute effects of pre-exercise stretching on physiological and metabolic responses, endurance performance, and perception of effort. Eight male endurance runners (age 36 ± 11 years) performed three running-until-exhaustion tests, preceded by three warm-ups, including the following different stretching protocols: static (SS), dynamic (DS), and no-stretching (NS). During the SS and DS sessions, the warm-up consisted of 10 min of running plus 5 min of SS or DS, respectively, while during the NS session, the warm-up consisted of 15 min of running. Physiological and metabolic responses, and endurance running performance parameters, were evaluated. The perception of effort was derived from the rating of perceived exertion (RPE). Running economy significantly improved after SS (p < 0.05) and DS (p < 0.01), and RPE values were significantly lower in SS (p < 0.05) and DS (p < 0.01), compared to NS. No differences in physiological and metabolic responses among the sessions were found. This study showed that including SS and DS within the warm-up ameliorated running economy and decreased the perception of effort during a running-until-exhaustion test, highlighting the benefits of stretching on endurance performance. These results should encourage recreational runners to insert stretching during warm-up, to optimize the running energy costs, reducing the perception of effort and making the training sessions more enjoyable.
