The effect of an expanded long-term periodization exercise training on physical fitness in patients with coronary artery disease: study protocol for a randomized controlled trial

Factors affecting adherence to physical training in the outpatient phase of rehabilitation, in patients after coronary artery bypass grafting

Aim      To evaluate the outpatient physical exercise (PE) compliance and the affecting factors in patients after coronary bypass (CB).Material and methods  The study included 67 men with ischemic heart disease younger than 75 years who had had CB. All patients were randomized to 2 groups: group 1 exercised on a bicycle ergometer at the rehabilitation center, under the monitoring of medical staff; patients of group 2 performed home-based exercise (HBE) by dosed walking. In the preoperative period, at one month after CB, and after 3 months of exercise, the following was evaluated: clinical condition of patients in different groups, plasma concentrations of lipids, body weight index, waist circumference, echocardiography and bicycle ergometry data, and questionnaire data (SF-36, Bek's Depression Inventory). At 3 months of follow-up, the outpatient exercise compliance and the affecting factors were also evaluated.Results The study demonstrated the effectiveness of the proposed alternative 3-month program of home-based PE. Both the patients exercising on a bicycle and those performing HBE had increased exercise tolerance (ET) and improved blood lipid concentrations. The number of obese patients decreased. Also, depression severity decreased, quality of life (physical and psychological components) improved, and compliance with drug therapy increased in both groups. Analysis of the training attendance in the recommended period showed that patients who had undergone CB were insufficiently adherent to physical rehabilitation programs, regardless of the program type (home-based or monitored). The highest PE adherence was observed in men with the following characteristics: married, working urban residents, with a previous history of cardiovascular diseases, who had regularly taken medications in the preoperative period, and who also had higher quality of life.Conclusion      The proposed outpatient 3-month physical rehabilitation programs increase the effectiveness of CB, which is evident as improved adherence to modifying cardiovascular risk factors, increased ET, optimization of the psychological status and quality of life, and improved compliance with drug therapy. However, despite the proposed alternative, home-based 3-month physical rehabilitation programs aimed at increasing the treatment compliance, the level of ET remained low. This requires further improvement of methods for monitoring and motivation of patients to physical rehabilitation and psychological support that would start already at the preoperative stage.

Effects of Two Different Exercise Training Programs Periodization on Anthropometric and Functional Parameters in People Living with HIV: A Randomized Clinical Trial

The purpose of this study was to investigate the effects of two different exercise training programs periodization on anthropometric and functional parameters in people living with HIV (PLHIV). This was a randomized clinical trial that involved participants (n = 31) living with HIV aged over 18 years and undergoing antiretroviral therapy which were randomized to periodized exercise training (PET; n = 13), non-periodized exercise training (NPET; n = 13), or control group (CON; n = 15). The PET and NPET groups performed 12 weeks of combined training while the CON group maintained the usual activities. Before and after 12 weeks of intervention were measured body composition and perimeters, muscle strength, Short Physical Performance Battery (SPPB) and Timed Up and Go (TUG) test time.

RESULTS

The PET and NPET groups increased fat-free mass (p < 0,001), right (p < 0,001) and left thigh perimeter (p < 0,001), muscle strength (p < 0,001), handgrip force (p < 0,001), and reduced the fat mass (p < 0,001), neck perimeter (p < 0,001), chair stand (p < 0,001), and time-up and go test time (p < 0,001) compared to CON. Furthermore, PET was significantly different to increase right thigh and muscle strength (p < 0,05) compared to NPET.

CONCLUSION

Both exercise training periodization protocols were effective to improve body composition and functional outcomes; however, seems that PET presents better results compare to NPET in PLHIV.

The effects of 12-months supervised periodized training on health-related physical fitness in coronary artery disease: a randomized controlled trial

We compared the impact of a one-year periodized exercise training versus a non-periodized exercise training on health-related physical fitness (HRPF) including body composition, cardiorespiratory and muscular fitness in patients with coronary artery disease (CAD). Fifty CAD patients (60.4 ± 9.9 years) were randomized to either a periodized training group (PG) (n = 25) or a non-periodized training group (NPG) (n = 25). Both consisted of a combined training programme, performed 3 days/week for 12 months. Thirty-six CAD patients (PG: n = 18, NPG: n = 18) successfully completed the exercise regimes. In both groups, a favourable main effect for time was evident for peak VO₂, peak workload, anaerobic threshold and respiratory compensation point workloads and VO₂, whole body skeletal muscle mass and quality index at 12 months.In conclusion, a periodized model is as effective as a non-periodized model in promoting increases in HRPF outcomes following a one-year intervention. These findings indicate that health-professionals can add variation to cardiac rehabilitation workouts without compromising effectiveness.

Periodization: Variation in the Definition and Discrepancies in Study Design

Over the past several decades, periodization has been widely accepted as the gold standard of training theory. Within the literature, there are numerous definitions for periodization, which makes it difficult to study. When examining the proposed definitions and related studies on periodization, problems arise in the following domains: (1) periodization has been proposed to serve as the macro-management of the training process concerning the annual plan, yet research on long-term effects is scarce; (2) periodization and programming are being used interchangeably in research; and (3) training is not periodized alongside other stressors such as sport (i.e., only resistance training is being performed without the inclusion of sport). Overall, the state of the literature suggests that the inability to define periodization makes the statement of its superiority difficult to experimentally test. This paper discusses the proposed definitions of periodization and the study designs which have been employed to examine the concept.

Intellectual disability, exercise and aging: the IDEA study: study protocol for a randomized controlled trial

BACKGROUND

People with intellectual disabilities (ID) have low levels of physical activity (PA) together with accelerated aging profiles. Adherence to PA interventions for persons with ID is low based on barriers such as motivation. The IDEA study aims to determine the effect of two types of exercise programs, continuous aerobic (CAEP) vs sprint interval training (SIT), designed for seniors with ID on health-related physical fitness, cardiovascular parameters, quality of life (QoL), and emotional and cognitive function.

METHODS

In this trial, ninety seniors with ID between the ages of 40 and 75 yrs. from occupational health centers from the Autonomous Region of Catalonia (Spain) will be recruited. Participants will be randomly allocated to the CAEP, SIT, and control group. Both intervention groups will train 3 days/week, 1.5 h/day over 6 months. Outcome variables will be assessed at baseline, 6 months and 12 months. The outcome variables include weight, height, body composition, cardiorespiratory fitness, muscle strength, balance, flexibility, cardiovascular parameters (blood pressure, pulse-wave velocity, pulse-wave analysis), QoL and cognitive function. The intervention effect will be determined with mixed models with repeated measures to assess changes in the outcome variables over time (baseline to month 12) and between study arms. Relationship between variables will be analyzed with appropriate regression analyses.

DISCUSSION

Various studies reported on CAEP and SIT as exercise interventions for persons with ID with beneficial outcomes on body composition, fitness and blood pressure. To our knowledge, this is the first trial designed to analyse the positive changes on fitness, PA levels, cardiovascular, QoL and cognitive function promoted by CAEP training and SIT in seniors with ID. The findings of this study will assist in the development of more effective exercise interventions to ensure better compliance and adherence to exercise in seniors with ID.

TRIAL REGISTRATION

The trial is registered at the ISRCTN registry. Registration number: ISRCTN43594228 . Registered 11 February 2019 - Retrospectively registered.

The effects of a comprehensive rehabilitation and intensive education program on anxiety, depression, quality of life, and major adverse cardiac and cerebrovascular events in unprotected left main coronary artery disease patients who underwent coronary artery bypass grafting

OBJECTIVE

This study aimed to explore the effect of a comprehensive rehabilitation and intensive education (CRIE) program on anxiety, depression, quality of life (QoL), and major adverse cardiac and cerebrovascular events (MACCE) risk in unprotected left main coronary artery disease (ULMCAD) patients who underwent coronary artery bypass grafting (CABG).

METHODS

In total, 300 ULMCAD patients who underwent CABG were randomly assigned to the CRIE group or usual care (UC) group in a 1:1 ratio. During a 12-month intervention, anxiety and depression were evaluated by Hospital Anxiety and Depression Scale (HADS), QoL was evaluated by 12-Item Short-Form Health Survey (SF-12), on discharge day from hospital (M0), and at 3 months after the discharge (M3), M6, and M12. All patients were further followed up until occurrence of MACCE or for an additional 24 months, and MACCE accumulating occurrence rate was calculated.

RESULTS

At M12, HADS-anxiety score and anxiety prevalence (17.3% vs. 29.3%) were decreased in the CRIE group than those in the UC group, meanwhile HADS-depression score and depression prevalence (15.3% vs. 24.7%) were also reduced in the CRIE group than those in the UC group. For QoL, SF-12 Physical Component Summary (PCS) score at M6/M12, and SF-12 PCS score change (M12 - M0) were increased in the CRIE group than those in the UC group; meanwhile, SF-12 Mental Component Summary (MCS) score at M12 and SF-12 PCS score change (M12 - M0) were increased in the CRIE group than those in the UC group as well. Besides, MACCE accumulating occurrence rate was numerically lower in the CRIE group compared with that in the UC group but without statistical significance.

CONCLUSIONS

CRIE is an effective approach in improving anxiety, depression, and QoL in ULMCAD patients who underwent CABG.

Quality of life after coronary artery bypass graft surgery - results of cardiac rehabilitation programme

Accountability, involvement, empowerment of the patients and families/caregiver, as well as the incentive for health behaviors based on physical exercise and healthy living habits with the support of health professionals, are fundamental in meeting the demands of the current society. The main objective of this report is to describe the process of developing skills in rehabilitation nursing that was possible in the context of the final stage in which an intervention program in the area of cardiac rehabilitation was designed, implemented and evaluated. In this quantitative study with exploratory characteristics, it was used the collection of observable and quantifiable data, from patients submitted to coronary artery bypass grafting. During the study, the Kolmogorov-Smirnov test was applied-being verified the normal distribution-and Student t-test, which aimed at comparing outcomes at the beginning and end of the program. When 6-min walk test was applied, there was an optimization of functional capacity (P=0.05), can be proved by the fact that all the patients had statistically significant improvements in the time-walk relationship. Furthermore, the quality of life in those who participated in the program was moderate in the preoperative period with 53.09%, and at the end a significant improvement was observed with 75.02%. Cardiac rehabilitation is fundamental in the patient submitted to coronary artery bypass grafting, taking into account the educational, physical exercise, and quality of life dimensions. Given the prevalence of risk factors associated with cardiovascular disease, differentiated intervention in rehabilitation nursing becomes essential in the training of patients for self-care.
