Improve Exercise Adherence Research Articles

MOVE-HF: an internet-based pilot study to improve adherence to exercise in patients with heart failure.

The use of the internet and newer activity monitors such as the Fitbit Charge HR to improve exercise adherence is limited. The primary aim of the Move on Virtual Engagement (MOVE-HF) was to investigate the effects of group social support by internet-based synchronized face-to-face video and objective physical activity feedback on adherence to recommended exercise guidelines. Thirty stable heart failure patients (New York Heart Association class I-III), aged 64.7±11.5 years, were randomly assigned to an experimental or comparison group. Participants were provided a handout on self-care in heart failure, an exercise routine, a Fitbit Charge HR and were asked to wear the Fitbit Charge HR daily, and record their exercise sessions using both the Fitbit Charge HR and exercise diaries. In addition, participants in the experimental group connected to Vidyo software, once a week, for 8 weeks, for a 45-minute face-to-face online group discussion/education session. Overall Vidyo session attendance was 68%, with 73% of participants attending five or more sessions. Adherence to exercise was 58.8% in the experimental group and 57.3% in the comparison group. The experimental group perceived receiving social support through the internet-based synchronized face-to-face video meetings but due to a small sample size and lack of adequate power, no significant impact on exercise adherence was observed. Participants commented that feedback regarding physical activity from the Fitbit Charge HR was helpful and motivational. Delivering social support by internet-based synchronized face-to-face video is feasible with heart failure patients. However, more investigations are needed to understand its impact on exercise adherence.

FITTSBALL – a dynamic tool for supervision of clinical exercise prescription

Introduction: Exercise rehabilitation/training is integral in the prevention and management of chronic, lifestyle-related diseases. Poor long-term adherence to exercise by patients is a challenging problem for health professionals. Despite the evidence of appropriate supervision with improved exercise adherence, the supervision process is not adequately described in the literature. Further, the co-existing Technical and Cognitive Behavioral components of exercise supervision are commonly described separately.Methodology: The literature search included (a) reviewing the Technical Domain (TD) of exercise prescription; and (b) Cognitive Behavioral Domain (CBD) of exercise adoption and adherence. CB theories were selected based upon their scientific evidence base demonstrating efficacy in intervention trails. The FITTSBALL tool was developed combining TD and CBD identifying multiple interactions. The tool was applied to 3 case scenarios to demonstrate efficacy.Results: “FITTSBALL” combined the technical domain of “FITT” (Frequency, Intensity, Time, and Type of exercise) and the cognitive behavioral domain (combining five theories and additional constructs) explained by “SBALL” (Stage of change, Belief and Ability of the client, Limitations and Life satisfaction). The tool describes the exercise supervision process and its associations as a three dimensional “sphere” traveling in a particular trajectory. Case scenarios on exercise adoption, maintenance, and relapse are described.Discussion: The “FITTSBALL” tool developed and detailed in this article provides both a meaningful description of supervision and a logical, generic framework for exercise prescription, concentrating on adherence and behavior change. The tool could be used by all staff responsible for supervision. This approach describes how the technical “FITT” principle of prescribing exercise can coexist with a range of cognitive and behavioral theories that have been posited to describe approaches to encourage behavior change and support adherence to such changes. Many such approaches have been widely studied over recent decades using interventional trials.Conclusion: “FITTSBALL” is a logical, generic framework for exercise prescription, concentrating on adherence and behavior change. To the best of our knowledge, such a comprehensive and coherent tool has not been presented to date.Implications for rehabilitationExercise training is integral in the management of chronic, lifestyle-related diseases, but long term adherence is a challenge.Exercise supervision improves adherence, but exercise supervision process is not adequately described in the literature.The tool “FITTSBALL” describes the supervision process and provides a logical, generic framework for exercise prescription and maintaining adherence to the behavior.The dynamic tool combines the traditional technical domain of “FITT” with the cognitive behavioral domain explained by “SBALL”.

The effect of running versus cycling high-intensity intermittent exercise on local tissue oxygenation and perceived enjoyment in 18-30-year-old sedentary men.

BackgroundHigh-intensity interval training (HIIT) has been proposed as a time-efficient exercise format to improve exercise adherence, thereby targeting the chronic disease burden associated with sedentary behaviour. Exercise mode (cycling, running), if self-selected, will likely affect the physiological and enjoyment responses to HIIT in sedentary individuals. Differences in physiological and enjoyment responses, associated with the mode of exercise, could potentially influence the uptake and continued adherence to HIIT. It was hypothesised that in young sedentary men, local and systemic oxygen utilisation and enjoyment would be higher during a session of running HIIT, compared to a session of cycling HIIT.MethodsA total of 12 sedentary men (mean ± SD; age 24 ± 3 years) completed three exercise sessions: a maximal incremental exercise test on a treadmill (MAX) followed by two experiment conditions, (1) free-paced cycling HIIT on a bicycle ergometer (HIITCYC) and (2) constant-paced running HIIT on a treadmill ergometer (HIITRUN). Deoxygenated haemoglobin (HHb) in the gastrocnemius (GN), the left vastus lateralis (LVL) and the right vastus lateralis (RVL) muscles, oxygen consumption (VO2), heart rate (HR), ratings of perceived exertion (RPE) and physical activity enjoyment (PACES) were measured during HIITCYC and HIITRUN.ResultsThere was a higher HHb in the LVL (p = 0.001) and RVL (p = 0.002) sites and a higher VO2 (p = 0.017) and HR (p < 0.001) during HIITCYC, compared to HIITRUN. RPE was higher (p < 0.001) and PACES lower (p = 0.032) during HIITCYC compared to HIITRUN.DiscussionIn sedentary individuals, free-paced cycling HIIT produces higher levels of physiological stress when compared to constant-paced running HIIT. Participants perceived running HIIT to be more enjoyable than cycling HIIT. These findings have implications for selection of mode of HIIT for physical stress, exercise enjoyment and compliance.

Behaviour change techniques associated with adherence to prescribed exercise in patients with persistent musculoskeletal pain: Systematic review.

PurposeExercise (planned, structured, repetitive movement) improves pain and function in people with persistent musculoskeletal pain (PMSK), but adherence is often poor. This systematic review evaluates the evidence from randomized controlled trials (RCTs) on the effectiveness of interventions to improve exercise adherence in people with PMSK and describes the content, context, and theoretical underpinning of behaviour change interventions designed to increase adherence.MethodsNine electronic databases were searched from inception dates to August 2017. Studies were included if they were RCTs that included adults with PMSK ≥3 months; ≥one measure of exercise adherence, exercise prescribed to both groups, and employed ≥one behaviour change technique (BCT) in the treatment group. Independent data extraction, theory coding, BCT taxonomy coding, and quality assessment using Cochrane Risk of Bias (RoB) tool was conducted by two reviewers.ResultsEight RCTs (five low, three high RoB) met inclusion criteria. Five trials reported between‐group differences in exercise adherence, favouring the treatment group. Three trials reported theoretical underpinning. There was moderate evidence that five BCTs, social support, goal setting, instruction of behaviour, demonstration of behaviour, and practice/rehearsal, improved exercise adherence. Interventions employing ≤seven BCTs, unique to those included in the control group, were most effective at enhancing exercise adherence.ConclusionsLimited moderate‐quality evidence supports using a small number of BCTs to enhance exercise adherence in people with PMSK. Further research should explore the associations and synergies between BCTs and explicitly report how theory was utilized. This may inform recommendations for health care professionals working with this population. Statement of contribution What is already known on this subject? Exercise (i.e., planned, structured, repetitive movements) improves pain and function in people with persistent musculoskeletal pain (PMSK).Many people with PMSK do not adhere to exercises prescribed by a health care professional.Little research has explored how to enhance adherence to prescribed exercise in people with PMSK. What does this study add? Moderate‐quality evidence from eight trials suggests behaviour change interventions enhance exercise adherence.Social support, goal setting, demonstration, instruction, and rehearsal were employed in effective interventions.Interventions with ≤7 behaviour change techniques were more effective at improving adherence than those employing >7.

Theoretical Rationale for How Slimming Garments May Motivate Physical Activity in People with Obesity

Obesity and inactivity contribute to disease burden and increased mortality worldwide. Consistency in initiating and maintaining adequate physical activity continues to be a major challenge. The majority of the weight loss and exercise science literature focuses on enhancing personal responsibility. For people with obesity, perceptions of others, a history of negative self-judgment and consequent low exercise self-efficacy influence the likelihood that they will engage in physical activity. We provide a theoretical rationale for the utility of slimming garments in enhancing exercise adherence. We reviewed and compiled relevant literature related to motivational theory and body image to develop a theoretical basis for the use of slimming garments to promote exercise adherence. Our review provides theoretical support for the potential for slimming garments to improve exercise adherence. Reductions in exercise avoidance may be achieved through the use of slimming garments during and following exercise.

A Wearable System for Real-Time Continuous Monitoring of Physical Activity.

Over the last decades, wearable systems have gained interest for monitoring of physiological variables, promoting health, and improving exercise adherence in different populations ranging from elite athletes to patients. In this paper, we present a wearable system for the continuous real-time monitoring of respiratory frequency (fR), heart rate (HR), and movement cadence during physical activity. The system has been experimentally tested in the laboratory (by simulating the breathing pattern with a mechanical ventilator) and by collecting data from one healthy volunteer. Results show the feasibility of the proposed device for real-time continuous monitoring of fR, HR, and movement cadence both in resting condition and during activity. Finally, different synchronization techniques have been investigated to enable simultaneous data collection from different wearable modules.

A systematic review of randomized controlled trials (RCTs) of exercise interventions using digital activity trackers (E-DAT) in cancer patients.

108 Background: Exercise ameliorates cancer and treatment-related toxicities but adherence to exercise is a barrier. Few studies in the general population suggest that E-DAT may improve exercise adherence. We conducted a systematic review to examine the effects of E-DAT on physical function, health-related quality of life (HRQOL), and serum inflammatory markers during and after cancer treatment. Methods: We used PubMed, Embase, and the Cochrane Library to identify RCTs of E-DAT in cancer patients aged ≥18 years published in English between 1/1/2008 and 7/27/2017. Two authors independently reviewed the titles of articles from the search (n = 160), removed duplicates (n = 49), and reviewed the remaining 111 articles for eligibility and substantive results. We excluded RCTs that used digital activity trackers solely for data collection. Results: Twelve RCTs met eligibility criteria, including 1,450 patients (mean age: 50-70 years) with the following cancers: breast (n = 5 RCTs), colon or breast (n = 2), prostate (n = 1), acute leukemia (n = 1) and various type (n = 3). Duration of E-DAT ranged from 4-24 weeks. Follow-up period was 4-24 weeks with retention of 54-95%. Half of the RCTs had E-DAT with in-person exercise training and the rest had self-directed training. The technology component of E-DAT included pedometers (n = 8); pedometers with smart phone application (n = 1), Wii-Fit (n = 1), or heart rate monitor (n = 1); and a wireless sensor with accelerometer, gyroscope, and magnetometer (n = 1). Adherence to E-DAT was &gt; 70% in 5 of 7 RCTs. Compared to controls (exercise interventions without digital activity trackers or standard of care), E-DAT significantly improved the step count in 60% of 5 RCTs, activity level in 56% of 9 RCTs, and HRQOL in 56% of 9 RCTs (all p &lt; 0.05), with no significant changes of inflammatory markers (i.e. TNF, CRP, c-peptide) in 2 RCTs. No significant correlations were found between duration of E-DAT with adherence (Spearman’s r = 0.16; p = 0.75) or study retention (Spearman’s r = -0.42; p = 0.17). Conclusions: This systematic review shows that E-DAT is feasible to implement in cancer patients. Future research should examine the optimal type, dose and schedule of E-DAT.

Perceived facilitators and barriers to physical exercise adherence in esophageal cancer patients after surgery.

94 Background: To achieve optimal effects of exercise interventions in esophageal cancer patients, high adherence is needed. Knowledge on facilitators and barriers can help improving exercise adherence. Hence, the aim of this study is to evaluate perceived facilitators and barriers to physical exercise adherence in esophageal cancer patients in the first year after surgery. Methods: Semi-structured interviews were conducted with patients (n = 16) who were randomised to the exercise group of the Physical ExeRcise Following Esophageal Cancer Treatment (PERFECT) Study. Patients participated in a 12-week supervised combined aerobic and resistance exercise program twice weekly, and were advised to be physically active at least 30 minutes each day. Physiotherapists registered attendance at the supervised sessions and compliance (i.e., performing the exercises according to protocol). Transcribed interviews were analysed using a thematic content approach. Results: Median attendance was 97.9%, interquartile range (IQR): 91.7 – 100%. Median compliance to both components of the exercise program was high: 89.6% (IQR 75.5 – 95.8%) for aerobic exercise and 88.0% (IQR 73.8 – 93.6%) for resistance exercise. The most important perceived facilitators were patients’ own attitudes towards exercise (i.e. motivation, commitment and personal goals) and supervision by a physiotherapist. There were only few perceived barriers, of which the most frequently mentioned were logistic factors (i.e. holidays, conflicting activities and weather circumstances) and impaired physical condition due to regular endoscopic esophageal dilation therapy or general physical complaints, such as fatigue. Conclusions: Esophageal cancer patients after surgery are well capable to perform physical exercise with moderate-to-high intensity. The most important perceived facilitators for the high adherence rates are patients’ own attitudes towards exercise and supervision by a physiotherapist. Completion of the exercise program was only minimally affected by perceived barriers as logistic factors and physical complaints. This information can help in designing future exercise programs for clinical practice.

Adherence to Technology-Based Exercise Programs in Older Adults: A Systematic Review.

Exercise participation and adherence in older people is often low. The integration of technology-based exercise programs may have a positive effect on adherence as they can overcome perceived barriers to exercise. Previous systematic reviews have shown preliminary evidence that technology-based exercise programs can improve physical functioning. However, there is currently no in-depth description and discussion of the potential this technology offers to improve exercise adherence in older people. This review examines the literature regarding older adults' acceptability and adherence to technology-based exercise interventions. A comprehensive systematic database search for randomized controlled trials, clinical controlled trials, and parallel group trials was performed, including MEDLINE, PsycINFO, EMBASE, CINAHL, EMB Reviews, and Cochrane Library, completed in May 2015. Trials reporting adherence to technology-based exercise programs aimed at improving physical function were included. Adherence was defined as the percentage of exercise sessions attended out of the total number of sessions prescribed. Twenty-two studies were included. The mean cohort age range was 67 to 86 years. Studies were conducted in research facilities, aged care facilities, and people's homes. Ten studies compared outcomes between technology-based and traditional exercise programs. Adherence to both types of interventions was high (median 91.25% and 83.58%, respectively). Adherence was higher for technology-based interventions than traditional interventions independent of study site, level of supervision, and delivery mode. The majority of the studies used commercially available gaming technologies, and both types of exercise interventions were mostly supervised. A lack of detailed reporting of adherence and the pilot nature of most studies did not allow computation of a comprehensive adherence rate. This systematic review provides evidence that technology offers a well-accepted method to provide older adults with engaging exercise opportunities, and adherence rates remain high in both supervised and unsupervised settings at least throughout the first 12 weeks of intervention. The higher adherence rates to technology-based interventions can be largely explained by the high reported levels of enjoyment when using these programs. However, the small sample sizes, short follow-up periods, inclusion of mostly healthy older people, and problems related to the methods used to report exercise adherence limit the generalizability of our findings. This systematic review indicates that technology-based exercise interventions have good adherence and may provide a sustainable means of promoting physical activity and preventing falls in older people. More research is required to investigate the feasibility, acceptability, and effectiveness of technology-based exercise programs undertaken by older people at home over extended trial periods.

Randomized Controlled Trial Investigating the Role of Exercise in the Workplace to Improve Work Ability, Performance, and Patient-Reported Symptoms Among Older Workers With Osteoarthritis.

The aim of this study was to evaluate the effectiveness of a 12-week workplace exercise program on work ability, performance, and patient-reported symptoms in older university employees with knee and/or hip osteoarthritis. Twenty-four participants with clinical hip and/or knee osteoarthritis were randomized to exercise or no exercise. At baseline and follow-up, several work (work ability, resilience), patient-reported (pain, physical function, depressive symptoms, self-efficacy), and performance outcomes (hip and knee strength, mobility performance) were measured. Significant improvements in work ability (P < 0.049) and patient-reported outcomes (pain, function, depressive symptoms) existed in the exercise group. No improvements were demonstrated in the no exercise group. Exercise in the workplace improved work ability and patient-reported symptoms in older workers with osteoarthritis. The benefits of workplace exercise programs should be studied in a larger sample in which attention is given to improving exercise adherence.

Development and delivery of a physiotherapist-led exercise intervention in a randomised controlled trial for subacromial impingement syndrome (the SUPPORT trial)

PurposeThis paper describes the development, content and delivery of a physiotherapist- led individualised, supervised and progressed exercise programme for use in a factorial randomised controlled trial testing treatments for subacromial impingement syndrome. MethodsTo develop the intervention, a survey of community physiotherapists and national guidelines provided the basis for a consensus workshop through which a protocol was developed for the SUPPORT trial physiotherapist-led exercise programme (SUPPORT: SUbacromial impingement syndrome and Pain: a randomised controlled trial Of exeRcise and injection). The protocol included three stages of exercise progression: (1) scapular stability and active exercise with no resistance (2) range of motion exercise with scapular control, isometrics and stretches, and (3) through range resistance exercise. A two day training programme was developed for physiotherapists which included the trial background, current evidence and strategies to improve exercise adherence. ResultsTwenty physiotherapists were trained to deliver the exercise intervention. In the SUPPORT trial, 128 participants were randomised to physiotherapist-led exercise. Ninety nine (81%) participants had their first physiotherapy session within 2 to 3 weeks and 71 (56%) received six to eight treatment sessions. Frequently-used exercises were: stage 1 scapular setting with glenohumeral joint (GHJ) flexion to 90°, stage 2 GHJ medial rotation stretch, stage 3 scapular setting through lateral rotation, with resistance bands. ConclusionWe combined clinical and research expertise with national guidance in order to develop a physiotherapist-led, individualised, progressed and supervised exercise intervention for use within a randomised trial. The effectiveness of the intervention is being evaluated within the SUPPORT trial.Trial registration number ISRCTN 42399123.

Effects of a tailor-made exercise program on exercise adherence and health outcomes in patients with knee osteoarthritis: a mixed-methods pilot study.

IntroductionPrevious studies showed that exercise intervention was effective in symptoms control of knee osteoarthritis (OA) but poor intervention adherence reduced the exercise effect. It has been suspected that the design of exercise intervention mainly from the health care professionals’ perspective could not address the patients’ barriers to exercise. Therefore, a tailor-made exercise program which incorporated the patient’s perspective in the design was developed and ready for evaluation.ObjectivesThis pilot study estimated the effects of a tailor-made exercise program on exercise adherence and health outcomes, and explored the participants’ perception and experience of the program.MethodsThe intervention of this study was a 4-week community-based group exercise program, which required the participants to attend a 1-hour session each week. Thirty-four older people with knee OA were recruited to the program. Mixed-methods study design was used to estimate the effects of this program and explore the participants’ perception and experience of the program. Exercise adherence and performance in return-demonstration of the exercise were assessed at 12 weeks after the program. Disease-specific health status (Western Ontario and McMaster Universities Osteoarthritis Index), general health status (12-item Short Form of the Medical Outcome Study Questionnaire), knee range of motion, muscle strength, and endurance of the lower extremities (Timed-Stands Test) were measured at the beginning of the program and 12 weeks after. Six participants were interviewed individually on the 12th week.ResultsThirty-three participants (75.0±7.3 years) completed the one-group pretest and post-test study. The participants’ exercise adherence was 91.4%±14.54%, and their correct performance in return-demonstration was 76.7%±21.75%. Most of the participants’ health outcomes significantly improved at posttests except the 12-item Short Form of the Medical Outcome Study Questionnaire physical health summary score. The qualitative findings provided rich information to explain and support the quantitative results.ConclusionThe results of this study showed that a tailor-made exercise program could improve exercise adherence and health outcomes in older people with knee OA.

Adherence to an online exercise program for COPD patients in the home environment- a pilot study

The objective of this study was to determine the adherence to an online exercise program for patients with moderate to very severe COPD in their home environment. The intervention consisted of three modules: module 1 online exercising; module 2 telemonitoring and module 3 telecommunication. Patients were instructed to use the service for 12 weeks after the normal rehabilitation period ended (aftercare). The study had a single-center exploratory study design. Adherence to module 1 was assessed by adherence to exercise sessions and log in time (duration in minutes) and frequency of training (amount of time a week) was measured for each patient. In addition, adherence to the exercises was measured as the percentage of performed exercises versus prescribed exercises. The adherence to module 2 was measured by logging the day and time the diary has been filled in. The adherence to module 3 was measured by logging the types of telecommunication options used. Satisfaction with the service was measured with a questionnaire, a number from 0 to 10 and whether patients would recommend the service to others. Twenty patients used the online exercise module. The adherence to the three weekly exercise protocol was 61 %. Patients logged in on average 20.3 min (±15) for 3.6 times a week (±2.3). The mean adherence to these exercises was 58 %. The adherence to the monitoring module was 82 %. Seventeen patients (77 %) used module 3 and send on average 9 messages (± 9.8) during the 12 weeks. Patient satisfaction with the service was high. The adherence to the home-based telemedicine service for patients with moderate to very severe COPD was similar to hospital-based maintenance exercise interventions. However, strategies to improve exercise adherence should be investigated.

High- and Low-Load Resistance Training: Interpretation and Practical Application of Current Research Findings.

Our current state of knowledge regarding the load (lighter or heavier) lifted in resistance training programmes that will result in 'optimal' strength and hypertrophic adaptations is unclear. Despite this, position stands and recommendations are made based on, we propose, limited evidence to lift heavier weights. Here we discuss the state of evidence on the impact of load and how it, as a single variable, stimulates adaptations to take place and whether evidence for recommending heavier loads is available, well-defined, currently correctly interpreted or has been overlooked. Areas of discussion include electromyography amplitude, in vivo and in vitro methods of measuring hypertrophy, and motor schema and skill acquisition. The present piece clarifies to trainers and trainees the impact of these variables by discussing interpretation of synchronous and sequential motor unit recruitment and revisiting the size principle, poor agreement between whole-muscle cross-sectional area (CSA) and biopsy-determined changes in myofibril CSA, and neural adaptations around task specificity. Our opinion is that the practical implications of being able to self-select external load include reducing the need for specific facility memberships, motivating older persons or those who might be less confident using heavy loads, and allowing people to undertake home- or field-based resistance training intervention strategies that might ultimately improve exercise adherence.

Interventions to achieve ongoing exercise adherence for adults with chronic health conditions who have completed a supervised exercise program: systematic review and meta-analysis

Objective: To determine which exercise adherence interventions are most effective for achieving ongoing exercise adherence in adults with chronic health conditions who had already completed a supervised short-term program. Method: Search of MEDLINE (Ovid Medline 1946 to April 8th, 2016), EMBASE (1980 to April 8th, 2016), CINAHL (1982-April 8th 2016) and the Cochrane Central Register of Controlled Trials was conducted. The chronic health conditions search terms as per the Chronic Disease and Participation in Work AIHW Report, 2008. Included were randomised (or quasi-randomised) trials and observational studies evaluating interventions that aimed to improve exercise adherence in adults with chronic health conditions that had completed a supervised exercise program. Random-effects meta-analyses and random-effects logistic meta-regression were used to examine relationships between exercise adherence strategy and adherence. Results: Eleven studies were included with a total of 1231 participants with Chronic Obstructive Pulmonary Disease, Diabetes, Cardiovascular disease or Osteoarthritis. Methods used for maintaining adherence were categorized post hoc as: centre based programs; home exercise programs with telephone follow-up; home exercise programs with no follow-up; and weaning programs that transitioned patients to an independent, off-site exercise program. There was no difference in the proportion of participants who were fully adherent to an exercise program 12 months between the centre-based follow-up (pooled proportion fully adherent=0.34) and telephone follow-up (pooled proportion fully adherent=0.30, difference p-value=0.75). Conclusion: Interventions such as centre-based exercise programs or home exercise programs (with or without telephone follow-up) do not differentially impact exercise adherence for people who have completed a short-term supervised program.

Rationale and methods for a randomized controlled trial of a movement-to-music video program for decreasing sedentary time among mother-child pairs.

BackgroundMeasured objectively, under a quarter of adults and fewer than half of preschool children meet the criteria set in the aerobic physical activity recommendations of the Centers for Disease Control and Prevention. Moreover, adults reportedly are sedentary (seated or lying down) for most of their waking hours. Importantly, greater amounts of sedentary time on parents’ part are associated with an increased risk of more sedentary time among their children. A randomized controlled trial targeting mother-child pairs has been designed, to examine whether a movement-to-music video program may be effective in reducing sedentary time and increasing physical activity in the home environment.MethodsMother-child pairs (child age of 4–7 years) will be recruited from among NELLI lifestyle-modification study five-year follow-up cohort participants, encompassing 14 municipalities in Pirkanmaa region, Finland.Accelerometer and exercise diary data are to be collected for intervention and control groups at the first, second and eighth week after the baseline measurements. Background factors, physical activity, screen time, motivation to exercise, and self-reported height and weight, along with quality of life, will be assessed via questionnaires. After the baseline and first week measurements, the participants of the intervention group will receive a movement-to-music video program designed to reduce sedentary time and increase physical activity. Intervention group mother-child pairs will be instructed to exercise every other day while watching the video program over the next seven weeks. Information on experiences of the use of the movement-to-music video program will be collected 8 weeks after baseline. Effects of the intervention will be analyzed in line with the intention-to-treat principle through comparison of the changes in the main outcomes between intervention and control group participants. The study has received ethics approval from the Pirkanmaa Ethics Committee in Human Sciences.DiscussionThe study will yield information on the effectiveness of movement-to-music video exercise in reducing sedentary behavior. Intervention-based methods have proven effective in increasing physical activity in home environments. Music may improve exercise adherence, which creates a possibility of achieving long-term health benefits.Trial registrationThe study is registered at ClinicalTrials.gov, as NCT02270138. It was registered on October 2, 2014.

Detection Of Exercise Errors Analyzing Time-series Video-captured Data

Fewer than thirty-three percent of adults adhere to exercise recommendations thereby increasing their risk of chronic diseases. This lack of participation may be due to lack of knowledge or skill in proper execution of exercises. Incorrectly performed exercises may decrease maximum benefit as well as increase the risk of injury. The ability to provide real-time exercise analysis feedback may improve exercise adherence and self-efficacy as well as reduce the risk of injury. PURPOSE: To examine if a newly designed approach of analyzing time-series exercise data collected by a camera can detect errors committed by participants. METHODS: Recreationally active males and females (N = 58) were videotaped performing 4 common exercises: squat (SQ), lunge (LU), jumping jacks (JJ) and high knees (HN). Each participant was randomly assigned to perform two of these exercises. Participants performed a maximum of 10 repetitions or to volitional fatigue. Time-series data from 15 body segments: head, neck, shoulders (2), elbows (2), wrists (2), spine, hips (2), knees (2) and ankles (2) were analyzed while performing these exercises. Potential errors in critical elements of performing these exercises were identified by a panel of experts. Geometric correlations of the spatial and temporal data were encoded to evaluate exercise performance. By analyzing the slope of the lines between the pairs of joints, angles and correlations, exercise errors were detected. RESULTS: In total, 98 data sets were collected: JJ (35), SQ (28), LU (23), HN (12). Error detection rates were: SQ (94.6%), JJ (92%), LU (90.6%), HN (88.3%) meaning that the respective percentage of exercise errors were detected when compared to the expert panel’s criteria. Fewer errors were detected with the high knees exercise. CONCLUSIONS: The system appears to be a low-cost effective means of providing real-time guidance in detecting exercise errors in 4 commonly performed exercises thereby potentially reducing the risk of injury and increasing adherence. Findings from the study reveal the value specially designed technology may have on teaching and assisting in proper execution of these selected common exercises.

Improving Exercise Adherence and Physical Measures in English-Speaking Latina Women.

Epidemiological data have established that lack of physical activity increases risk factors for chronic diseases. Data also suggests that physical activity participation is lowest in minority women, particularly Latinas, and that the nature of the exercise and attitudes toward exercise may influence exercise adherence. The purpose of this study was to determine the effect of hypertrophy training (HT) or power training (PT) used concomitantly with evaluative conditioning (EC) or neutral conditioning (NC) on exercise adherence as well as in physical and psychosocial variables in Latina women. EC is a behavioral method using paired stimuli to develop and strengthen new associations in memory. Two hundred thirty-one English-speaking Latina women (mean ± SD, age 36.8 ± 15.9 years) were randomly assigned to standard HT or high-speed circuit PT and then further stratified to receive EC or NC. One hundred forty-two Latina women completed pre- and posttesting. For HT, EC produced significantly greater exercise time across the training period than NC. HT and PT both significantly improved all physical, functional, and psychosocial variables, with exception of leg extension and usual gait speed (p < 0.05). EC can positively impact exercise adherence during HT in Latina women; while body composition, neuromuscular, and functional performances can be increased using HT and PT independent of psychological conditioning.
