The uptake and benefits of the Canadian Physical Activity Guidelines for Adults with Multiple Sclerosis (PAGs) have been validated, but there is limited understanding regarding the knowledge, needs, and preferences of people with multiple sclerosis (MS) for implementing the PAGs outside of clinical research. The authors conducted online, semistructured interviews with 40 persons with MS from across the United States seeking information on awareness of and potential approaches for increasing the uptake of the PAGs. They identified first impressions and potential approaches for increasing the uptake of the PAGs through inductive, semantic thematic analysis. Participants perceived the PAGs as a good introduction for structured exercise but desired more information on how to meet the PAGs. Participants further believed that modifying the PAGs for inclusivity and applying a multifaceted approach for dissemination and implementation may increase uptake of exercise behavior. Physical activity research in MS should include both analyzing the effects of exercise and the unique challenges faced by persons with MS in putting the PAGs into practice.
Instrument-assisted soft tissue mobilization (IASTM), tissue flossing, and kinesiology taping are increasingly popular treatments among athletes for improving functional performance, despite limited evidence for their efficacy.

Previous research regarding the efficacy of soft tissues and neuromuscular techniques on improving functional capacity of shoulder joints in athletes has yielded conflicting results. We examined the immediate and short-term effects of IASTM, flossing, and kinesiology taping on the functional capacities of amateur athletes' shoulders.

Randomized controlled study.

Clinical assessment laboratory.

Eighty amateur overhead athletes (mean [SD] age = 23.03 [1.89]; weight = 78.36 [5.32]; height = 1.77 [.11]).

We randomly assigned participants to 4 research sub-groups in which they received the following treatments on their dominant shoulders IASTM (n = 20), flossing (n = 20), both IASTM and flossing (n = 20), and kinesiology tape (n = 20). Nondominant shoulders served as controls.

ndings from the current study support the use of novel soft tissue and neuromuscular techniques for the immediate and short-term improvement of the shoulder functional capacities in amateur overhead athletes.
To examine the effect of growth hormone (GH) treatment on physical performance in children with idiopathic short stature and normal GH secretion.

A total of 24 children participated in the study (13 GH-treated, 11 non-treated, aged 8-13y, 11 males and 13 females, Tanner stage 1-2). Participants performed a battery of motor skill performance tests (Eurofit), as well as the Wingate anaerobic test.

No statistically significant differences in any of the Eurofit physical fitness test results (eg,20-m shuttle run 33.0 [15.1] vs 25.1 [21.0] laps in treated and nontreated participants, respectively, P = .25) or the Wingate anaerobic test were found between the groups (eg,peak power 5.0 [2.9] vs 3.9 [2.6]watts/kg in treated and nontreated participants, respectively, P = .2).

Therapeutic usage of exogenous GH for pre and early pubertal children with idiopathic short stature and normal GH secretion was not associated with beneficial effects on physical performance indices. This suggests that the use of GH as a potential performance enhancing agent, in this age group, at least at commonly used doses, is not advantageous.

Sixteen participants were assessed before and immediately after both stretching modalities. Kinematics of movement was measured by an optoelectronic system and esthetics was scored by a jury of professional dancers. Both stretching modalities led to significant kinematic differences compared with without stretching. Significant linear correlations between kinematic parameters and esthetic scores have been observed improving dancers' physical performances has noticeable impact on the perception of their movements.
The effects of compliance with the US Physical Activity (PA) Guidelines and changes in compliance over time on cardiovascular disease (CVD) mortality are unknown.

Male participants in the Aerobics Center Longitudinal Study (n = 15,411; 18-100y) reported leisure-time PA between 1970 and 2002. GDC-0068 The frequency of and time spent in PA were converted into metabolic equivalent minutes per week. The participants were classified into remained inactive, became active, became inactive, or remained active groups according to their achievement of the PA guidelines along the follow-up, equivalent here to at least 500 metabolic equivalent minutes of PA per week. Cox regression adjusted for different models was used for the analyses, using age, body mass index, smoking and drinking status, hypertension, diabetes, hypercholesterolemia, and parental history of CVD.

Over a mean follow-up of 6.2 years, 439 CVD deaths occurred. Consistently meeting the PA guidelines, compared with not meeting, was associated with a 54% (95% confidence interval, 0.32-0.67) decreased risk of CVD mortality. After controlling for all potential confounders, the risk reduction was 47% (95% confidence interval, 0.36-0.77).

Maintaining adherence to the PA guidelines produces substantial reductions in the risk of CVD deaths in men. Furthermore, discontinuing compliance with the guidelines may offset the beneficial effects on longevity.
