The Constituent Year Effect: Relative Age Disparities in Australian Masters Track and Field Athletic Participation

Psychosocial Aspects of Participation in Competitive Sports Among Older Athletes: A Scoping Review

BACKGROUND AND OBJECTIVES

In the last decade, sport has been considered a tool in active aging to maintain physical fitness, improve mental wellbeing and form social relationships among older people. However, a thorough psychosocial understanding of the phenomenon of older athletes competing in sports events is lacking. Most research has focused on competitive sports participation in the young population. This study analyzes the general state of knowledge of competitive sports participation among athletes aged 50 years and older from a psychosocial perspective.

RESEARCH DESIGN AND METHODS

We followed the five-step process outlined by Arksey and O'Malley (2005) and expanded by Levac and colleagues (2010). After the search in four electronic databases, 69 peer-reviewed articles met the inclusion criteria.

RESULTS

The findings indicate that psychosocial research into older people's participation in competitive sports has grown moderately in the last decade. While intrapersonal and interpersonal aspects have dominated the academic psychosocial discourse on older athletes' competitive sports participation, aspects related to the environment/community and policy have largely been overlooked.

DISCUSSION AND IMPLICATIONS

We identified several critical gaps in the literature, classified into conceptual (e.g., lesser attention to personality, emotional and cognitive aspects), methodological (e.g., longitudinal studies almost absent), and diverse aspects (e.g., focus on a wide indiscriminate age range; few comparisons between types of sports; underrepresentation of some nation or world regions as well as few cross-national comparative studies). These research gaps hint at opportunities that future research on older people's participation in competitive sports should address.

Why Are Masters Sprinters Slower Than Their Younger Counterparts? Physiological, Biomechanical, and Motor Control Related Implications for Training Program Design

Elite sprint performances typically peak during an athlete's 20s and decline thereafter with age. The mechanisms underpinning this sprint performance decline are often reported to be strength-based in nature with reductions in strength capacities driving increases in ground contact time and decreases in stride lengths and frequency. However, an as-of-yet underexplored aspect of Masters sprint performance is that of age-related degradation in neuromuscular infrastructure, which manifests as a decline in both strength and movement coordination. Here, the authors explore reductions in sprint performance in Masters athletes in a holistic fashion, blending discussion of strength and power changes with neuromuscular alterations along with mechanical and technical age-related alterations. In doing so, the authors provide recommendations to Masters sprinters-and the aging population, in general-as to how best to support sprint ability and general function with age, identifying nutritional interventions that support performance and function and suggesting useful programming strategies and injury-reduction techniques.

Constituent Year Effect in Masters Sports: An Empirical View on the Historical Development in US Masters Swimming

A participation-related constituent year effect, has been found to exist in masters sports in that relatively younger masters athletes (i.e., those in the first or second year of a 5-year age category) participate in competitions significantly more often than relatively older masters athletes (i.e., those in the fourth or fifth year of a 5-year age category). The main purpose of this study was to examine if the participation-related constituent year effect in US masters swimming always existed or if it has developed over time at different historical time periods. Using archived data, participation in the US Masters national short course swimming championships at each of the historical time periods in years 1972, 1982, 1992, 2002, 2012 and 2016 were examined as a function of an individual's constituent year within any 5-year age category and across gender and age. The results indicated the existence of a participation-related constituent year effect for each of the six time periods. In particular, a participation-related constituent year effect seemed to have existed from the inception of organized masters swimming competitions in the US but has developed more strongly over the years especially for males and older-aged masters swimmers. Generally, the tendency to participate at National swimming competitions during the first year of an age category was significantly more pronounced, whereas the tendency of participating during the fifth year of an age category was lower. Findings suggest that the 5-year age categories may not provide an equal competitive opportunity especially for relatively older athletes as for those who are relatively younger, but may encourage more strategic periodized training and participation.
