Purpose: The purpose of this study was to examine the psychological responses to intermittent activities of varying intensities and types among children with and without asthma. Methods: A total of 37 children and adolescents (51% male, aged 8–16 y, 54% nonwhite, and 54% without asthma) participated in this study. Participants completed 5 exercises in the same order: self-paced walking, resistance activities, dance video, gamified obstacle course, and step test. In-task mood was assessed using the Feeling Scale, in-task perceived exertion was assessed via the ratings of perceived exertion scale, and postactivity enjoyment was assessed using the Physical Activity Enjoyment Scale. Results: There was a significant main effect of exercise type on mood (P < .001), ratings of perceived exertion (P < .001), and enjoyment (P < .002). There was not a significant main effect of asthma status on mood, ratings of perceived exertion, or enjoyment (Ps > .05). Children with asthma reported significantly lower in-task mood during the step exercise (P < .037) and reported significantly lower postactivity enjoyment after the walk and obstacle course exercises (Ps < .03). Conclusions: Regardless of differences by asthma status for in-task mood during the obstacle course and for postactivity enjoyment during the walk and step exercises, both children with and without asthma reported high in-task mood and postactivity enjoyment during all 5 exercises.

effects on viral load or CD4+ count. The evidence reviews, and resultant guidelines, are primarily focused on the preventive rather than therapeutic effects of either PA or MVPA. That is, prevention of an additional chronic condition (ie, a secondary cancer, T2D, or CVD mortality) or prevention (ie

Pes planus is a prevalent chronic condition with a reported incidence of 2% to 23% in the adult population and characterized by the lower medial longitudinal arch (MLA) with calcaneal eversion. 1 – 3 The most common problem associated with pes planus is excessive pronation during weight

Exercise-induced leg pain (EILP) is a broad term related to pain topic. 1 EILP is a chronic condition that generally arises in elite and recreational athletes’ lower quarter of the legs. In addition, it is a common condition in those who exercise regularly. The incidence grows as the number of

Despite well-documented health benefits, adults with a physical chronic condition do not meet the recommended physical activity (PA) guidelines. Therefore, secondary prevention programs focusing on PA are needed. Web-based interventions have shown promise in the promotion of PA behavior change. We conducted a systematic review to summarize the evidence about the effectiveness of web-based PA interventions in adults with chronic disease.


Articles were included if they evaluated a web-based PA intervention and used a randomized design. Moreover, studies were eligible for inclusion if they used a non- or minimal-treatment control group and if PA outcomes measures were applied. Seven articles were included.


Three high-quality studies were statistically significant to the control group, whereas 2 high- and 2 low-quality studies reported nonsignificant findings.


Our best evidence synthesis revealed that there is conflicting evidence on the effectiveness of web-based PA interventions in patients with a chronic disease.

This study examined participant demographic and physical function characteristics from EnhanceFitness, an evidence-based physical activity program for older adults. The sample consisted of 19,964 older adults. Participant data included self-reported health and demographic variables, and results for three physical function tests: chair stand, arm curls, and timed up-and-go. Linear regression models compared physical function test results among eight program site types. Participants were, on average, 72 years old, predominantly female, and reported having one chronic condition. Residential site participants’ physical function test results were significantly poorer on chair stand and timed up-and-go measures at baseline, and timed up-and-go at a four-month follow-up compared with the reference group (senior centers) after controlling for demographic variables and site clustering. Evidence-based health-promotion programs offered in community settings should assess demographic, health, and physical function characteristics to best serve participants’ specific needs, and offer classes tailored to participant function and ability while maintaining program fidelity.

Cross-education enhances the performance of muscles not directly involved in the chronic conditioning of the muscles in a remote limb. Substantial cross-education occurs after training with eccentric contractions or with contractions evoked by electromyostimulation (EMS). Since during EMS and eccentric contractions, skin and muscle afferents are activated that have excitatory effects on contralateral homologous muscles, it was hypothesized that exercise training with stimulated vs. voluntary eccentric contractions would lead to greater cross-education. Thirty-two women were randomly assigned to a voluntary (Vol), an EMS, or a remote EMS (rEMS) exercise group and performed 840 voluntary or stimulated eccentric contractions over 6 weeks. All subjects, including nonexercising controls (Con), were tested pre- and posttraining for maximal voluntary and stimulated isometric and eccentric quadriceps strength. Ipsilateral voluntary and stimulated forces increased in all groups. Changes in EMG activity paralleled those in voluntary force in each limb. No changes occurred in grip strength. The greater contra- and ipsilateral strength gains after EMS training were most likely related to an additive effect of EMS and muscle lengthening.
