Factors influencing participation in outdoor physical activity promotion schemes: The case of South Staffordshire, England

Policy exhortations for promoting outdoor physical activity have increased considerably in England and Wales over the past 20 years. Despite a considerable number of schemes developing during this period to encourage physical activity and exercise, marked population-level changes in outdoor physical activity behaviour have not been seen. The paper explores the triggers to this participation using a five-fold classification: physical infrastructure; information infrastructure; administrative infrastructure; participant constraints and participant preferences. Through a series of interviews in a case study 'healthy exercise' scheme in South Staffordshire, a district local authority in England, these triggers to participation are identified and explored. It is concluded that whilst the infrastructure triggers can be manipulated by scheme providers in an attempt to improve scheme participation, participant triggers fall largely beyond the control of scheme providers. Research suggests, too, that participant triggers tend to be stronger than infrastructure ones. Because of this, where there is a lack of healthy exercise scheme success, this cannot necessarily be attributed to scheme providers as it might be as a result of user triggers. For the same reason, it might be beyond the influence of scheme providers to turn 'failing' exercise schemes into successful ones. © 2012 Copyright Taylor and Francis Group, LLC

Exercise, Service and Support: Client Experiences of Physical Activity Referral Schemes(PARS)

Physical activity referral schemes (PARS) represent one of the most prevalent interventions in the fight against chronic illness such as coronary heart disease and obesity. Despite this, issues surrounding low retention and adherence continue to hinder the potential effectiveness of such schemes on public health. This article reports on the second stage of a larger investigation into client experiences of PARS focusing specifically on findings from five client-based focus groups and interviews with five Scheme Organisers. The resulting analysis reveals three main factors impacting participant perceptions of the quality of service and support received: the organisation of PARS provision, client engagement with the PARS community and the nature and extent of client support networks. The article demonstrates that staff have a considerable role to play in engaging clients in the PARS system and that Scheme Organisers should give serious thought to ensuring that clients have valuable and sustainable networks of support. Furthermore, it is suggested that Scheme Organisers need to facilitate a system in which staff are genuinely engaged with the needs of clients and are able to provide individualised programmes of physical activity

Heart rate variability: response following a single bout of interval training

We investigated the effect of exercise on heart rate variability by analysing the heart rate power spectrum prior to, and 1 and 72 h following, an interval training session. Subjects initially performed a graded test to exhaustion to determine maximal oxygen uptake (V˙O2max) and the running speed at which V˙O2max was first attained (vV˙O2max). The training session was completed on a separate day and comprised six 800 m runs at 1km × h-1 below vV˙O2max. Prior to the training session (pre), 1 h following the training session (+ 1h), and 72 h following the training session (+ 72h), subjects sat quietly in the laboratory for 20 min whilst breathing frequency was maintained at 12 breath × min-1. Cardiac cycle R-R interval data were collected over the final 5 min of each 20 min period and analysed by means of autoregressive power spectral analysis to determine the high frequency (HF) and low frequency (LF) components of heart rate variability. Heart rate was higher, and the standard deviation of the R-R intervals was lower, at + 1 h than for pre or + 72 h (p < 0.05). The HF and the LF components of heart rate variability were also lower (p < 0.05) for + 1 h than for pre or + 72 h when the data were expressed in ms2. However, no changes in the LF:HF ratio were observed, and the changes in the HF and LF components disappeared when the data were expressed as a fraction of the total power. Whilst these findings illustrate the importance of controlling the timing of exercise prior to the determination of heart rate variability, the time course of the post-exercise heart rate variability response remains to be quantified

Exploring the Potential of Case Formulation Within Exercise Psychology

The purpose of this article is to expand the literature on case formulation as a clinical tool for use within exercise psychology, generally and lifestyle behavior change interventions, specifically. Existing research offers limited support for the efficacy of current physical activity behavior change intervention strategies, particularly in the long-term. The present paper argues that intervention strategies need to pay greater attention to the complex and individualistic nature of exercise and health related behaviors. It has been suggested that existing intervention designs tend to conform to a medical model approach, which can at times potentially neglect the complex array of personal and situational factors that impact on human motivation and behavior. Case formulation is presented as a means of encouraging a dynamic and comprehensive approach to the development and implementation of practical interventions within the health behavior change field. The adoption of these clinical techniques may facilitate the careful consideration of variations in the development, manifestation, and maintaining mechanisms of problematic behaviors (e.g., inactivity). An overview of case formulation in its different forms is presented alongside a justification for its use within exercise psychology
