The results suggest that regular intensive exercise in older male subjects is associated with higher growth hormone and testosterone levels and that exercise may have a role in counteracting the normal decline in growth hormone with ageing.
Background:Physical activity has emerged as a distinct area of public health practice. As this field evolved, the need for a professional organization for physical activity practitioners in public health became evident. A collaboration of several existing public health professional organizations formed to address this new area of public health practice. The collaboration laid the foundation to establish a professional organization. National Association of Physical Activity Practitioners in Public Health (NSPAPPH) was launched in April 2006. NSPAPPH accomplishments to date include convening a national meeting of physical activity practitioners, conducting strategic planning, adopting bylaws and core competencies for professional practice, developing a website and electronic newsletter, and establishing training opportunities for practitioners.Conclusions:Future plans for NSPAPPH include development of a professional certification for physical activity practitioners in public health; enhancement of training and professional development opportunities; recruitment of members from national, tribal, state, and local organizations working in public and private sectors; publications of journal articles, reports, and issue briefs; and development of a policy agenda. Implementing these plans will serve to strengthen public health infrastructure for physical activity, thus improving the physical activity behaviors of Americans and the health of the nation.
The purpose of this article is to describe the rationale and procedure employed in developing the Move More North Carolina: Recommended Standards for After-School Physical Activity, which was publicly released statewide in April 2009. The Standards outline evidenced-based best practices for after-school programs to implement in order to increase amount and quality of physical activity (PA) among program participants. The Standards can be applied in any after-school program and were developed to benefit the approximately 152,000 school-aged children who are served by NC after-school programs each year. These programs often serve children at high risk for physical inactivity, including children from racial/ethnic minorities, impoverished areas, with disabilities, and/or living in neighborhoods with limited PA opportunities. The rationale for developing standards for PA in after-school programs is threefold: (1) such programs can provide enjoyable, safe, and age-appropriate PA; (2) they can facilitate family involvement, community partnership, and increase access to PA resources; and (3) they serve children at risk for inactivity. Recommended best practices are included for the following categories: time/intensity, qualified staff/training, curriculum, program size, facilities, equipment, and evaluation. Methods used to inform The Standards included a planning team, on-line surveys, focus groups, a systematic literature review, a consensus panel, and external expert review. The impact of The Standards is yet to be seen, but the collaborative process used in their creation can serve as a model for the development of similar PA standards in other states.
