Aging and the Social Cognitive Determinants of Physical Activity Behavior and Behavior Change: Evidence from the Guide to Health Trial

Part one of this study investigated the effect of aging on social-cognitive characteristics related to physical activity (PA) among adults in the baseline phase of a health promotion intervention. Participants' questionnaire responses and activity logs indicated PA levels and self-efficacy declined with age, while social support and the use of self-regulatory behaviors (e.g., goal setting, planning, and keeping track) increased. With age participants were also less likely to expect PA to interfere with their daily routines and social obligations. Part two of the study was among overweight/obese, inactive participants completing the intervention; it examined whether improvements in psychosocial variables might counteract declining PA associated with age. After treatment, participants were more active and decreased body weight regardless of age, and improved self-efficacy, outcome expectations, and self-regulatory behaviors. In a causal model, increases in self-efficacy at 7-months lead to increased PA levels and, albeit marginally, weight loss at 16 months; increased PA was associated with greater weight loss. Aging adults who were more confident exercised more and as a result lost more weight. This longitudinal study suggests interventions that offset the effect of aging on self-efficacy may be more successful in helping older participants become more active and avoid weight gain

Supervision during resistance training: a comparison of trainer and trainee perceptions

Background: Resistance training has well-documented health benefits; however, participation and adherence remain overwhelmingly low. Supervision has been evidenced to improve adherence, and produce favourable adaptations compared to unsupervised resistance training. A recent exploratory systematic review and meta-analysis on supervision during resistance training noted a lack of clarity as to the purpose/intent of the supervisor within the body of literature.Methods: An online cross-sectional survey study was conducted in English and distributed primarily across social media platforms and through the authors’ personal and professional networks. The aim of the survey was to compare the perceptions of supervision between trainers and trainees. Secondary outcomes included exploratory analyses of the impact of training experience, sex of participant, and comparison based on supervision type.Results: 468 participants completed all elements of the survey (68% male, 32% female). Of which 236 were personal trainers/strength coaches, and 232 were trainees. In brief, descriptive data from the survey suggest that trainers perceived supervision as more important than trainees for the characteristics and variables measured. Females perceived supervision in resistance training as more important than males. Trainees who engage in supervised resistance training reported supervision to be more important compared to those training alone or with a training partner. Technical coaching was reported to be the most important characteristic of supervision. Finally, trainers and trainees engaging in supervised strength training reported lower injury rates compared to those strength training unsupervised or with a training partner. Qualitative data are presented regarding perceptions of how and why supervision should differ based on sex, age, and experience, as well as reporting injury experiences.Conclusion: Our data suggest that the perceived benefits of supervision vary based on population. We posit that the present data have implications for both trainers and trainees, which might serve to strengthen a relationship by aligning roles and realising goals in supervised resistance training. Further, this data might provide insight and prompt future research as to how to engage more people into resistance training

Aging, Resistance Training, and Diabetes Prevention

With the aging of the baby-boom generation and increases in life expectancy, the American population is growing older. Aging is associated with adverse changes in glucose tolerance and increased risk of diabetes; the increasing prevalence of diabetes among older adults suggests a clear need for effective diabetes prevention approaches for this population. The purpose of paper is to review what is known about changes in glucose tolerance with advancing age and the potential utility of resistance training (RT) as an intervention to prevent diabetes among middle-aged and older adults. Age-related factors contributing to glucose intolerance, which may be improved with RT, include improvements in insulin signaling defects, reductions in tumor necrosis factor-α, increases in adiponectin and insulin-like growth factor-1 concentrations, and reductions in total and abdominal visceral fat. Current RT recommendations and future areas for investigation are presented

The Impact of Coronavirus (COVID-19) Related Public-Health Measures on Training Behaviours of Individuals Previously Participating in Resistance Training: A Cross-Sectional Survey Study

Introduction Understanding the impact of lockdown upon resistance training (RT), and how people adapted their RT behaviours, has implications for strategies to maintain engagement in similar positive health behaviours. Further, doing so will provide a baseline for investigation of the long-term effects of these public health measures upon behaviours and perceptions, and facilitate future follow-up study. Objectives To determine how the onset of coronavirus (COVID-19), and associated ‘lockdown’, affected RT behaviours, in addition to motivation, perceived effectiveness, enjoyment, and intent to continue, in those who regularly performed RT prior to the pandemic. Methods We conducted an observational, cross-sectional study using online surveys in multiple languages (English, Danish, French, German, Italian, Portuguese, Slovakian, Swedish, and Japanese) distributed across social media platforms and through authors’ professional and personal networks. Adults (n = 5389; median age = 31 years [interquartile range (IQR) = 25, 38]), previously engaged in RT prior to lockdown (median prior RT experience = 7 years [IQR = 4, 12]) participated. Outcomes were self-reported RT behaviours including: continuation of RT during lockdown, location of RT, purchase of specific equipment for RT, method of training, full-body or split routine, types of training, repetition ranges, exercise number, set volumes (per exercise and muscle group), weekly frequency of training, perception of effort, whether training was planned/recorded, time of day, and training goals. Secondary outcomes included motivation, perceived effectiveness, enjoyment, and intent to continue RT. Results A majority of individuals (82.8%) maintained participation in RT during-lockdown. Marginal probabilities from generalised linear models and generalised estimating equations for RT behaviours were largely similar from pre- to during-lockdown. There was reduced probability of training in privately owned gyms (~ 59% to ~ 7%) and increased probability of training at home (~ 18% to ~ 89%); greater probability of training using a full-body routine (~ 38% to ~ 51%); reduced probability of resistance machines (~ 66% to ~ 13%) and free weight use (~ 96% to ~ 81%), and increased probability of bodyweight training (~ 62% to ~ 82%); reduced probability of moderate repetition ranges (~ 62–82% to ~ 55–66%) and greater probability of higher repetition ranges (~ 27% to ~ 49%); and moderate reduction in the perception of effort experienced during-training (r = 0.31). Further, individuals were slightly less likely to plan or record training during lockdown and many changed their training goals. Additionally, perceived effectiveness, enjoyment, and likelihood of continuing current training were all lower during-lockdown. Conclusions Those engaged in RT prior to lockdown these behaviours with only slight adaptations in both location and types of training performed. However, people employed less effort, had lower motivation, and perceived training as less effective and enjoyable, reporting their likelihood of continuing current training was similar or lower than pre-lockdown. These results have implications for strategies to maintain engagement in positive health behaviours such as RT during-restrictive pandemic-related public health measures

A higher effort-based paradigm in physical activity and exercise for public health: making the case for a greater emphasis on resistance training

It is well known that physical activity and exercise is associated with a lower risk of a range of morbidities and all-cause mortality. Further, it appears that risk reductions are greater when physical activity and/or exercise is performed at a higher intensity of effort. Why this may be the case is perhaps explained by the accumulating evidence linking physical fitness and performance outcomes (e.g. cardiorespiratory fitness, strength, and muscle mass) also to morbidity and mortality risk. Current guidelines about the performance of moderate/vigorous physical activity using aerobic exercise modes focuses upon the accumulation of a minimum volume of physical activity and/or exercise, and have thus far produced disappointing outcomes. As such there has been increased interest in the use of higher effort physical activity and exercise as being potentially more efficacious. Though there is currently debate as to the effectiveness of public health prescription based around higher effort physical activity and exercise, most discussion around this has focused upon modes considered to be traditionally ‘aerobic’ (e.g. running, cycling, rowing, swimming etc.). A mode customarily performed to a relatively high intensity of effort that we believe has been overlooked is resistance training. Current guidelines do include recommendations to engage in ‘muscle strengthening activities’ though there has been very little emphasis upon these modes in either research or public health effort. As such the purpose of this debate article is to discuss the emerging higher effort paradigm in physical activity and exercise for public health and to make a case for why there should be a greater emphasis placed upon resistance training as a mode in this paradigm shift

Current behavior modification in the classroom: be still, be quiet, be docile

Classrooms have recently been criticized as total institutions where there is a rigid preoccupation with order and control, and where children are required to be still, to be silent, and to obey. Behavior modification has been described as a major source of change in the classroom. A review of this journal's papers on behavior modification in the classroom indicated that inappropriate behavior has been consistently defined as behavior that interferes with order, quiet, and stillness. It is argued therefore, that behavior modification has supported rather than changed the questionable status quo. Alternative areas for behavior modification in traditional classrooms and the role of behavior modification in the development of open classrooms are discussed

Development and Evaluation of an HIV-Risk Reduction Program for Female College Students

College students are engaging in high rates of behavior related to risk of infection from human immunodeficiency virus (HIV) & other sexually transmitted diseases (STDs). Here, a cognitive-behavioral skills training program for heterosexual college females (N = 11) focusing on sexual assertiveness skills & the reduction of risk-related behaviors was designed & evaluated, as compared with an education-only program. Participants completed preintervention, postintervention, & one-month follow-up assessments of: (1) HIV-/STD-related knowledge & beliefs; (2) sexual, & alcohol- & drug-related behaviors; & (3) sexual assertiveness role-plays. Skills training participants compared to education-only participants scored higher on sexual assertiveness skills, specific knowledge of HIV infection, & self-efficacy, & reported a reduction in risk-related behaviors at postintervention & follow-up assessments. 3 Tables, 23 References.
