Exploring the Motivation of Adolescent’ Participation in Physical Exercise: An Evolutionary Psychology Perspective
Abstrct
The extant scholarly discourse pertaining to adolescents' engagement in physical exercise predominantly comprises superficial observations and introductory comprehension, demonstrating a dearth of comprehensive analysis regarding the intricate psychological mechanisms at play. This investigation endeavours to delve into the foundational impetuses driving teenagers' participation in physical activity through the lens of evolutionary psychology theory. Furthermore, it aims to scrutinize the motivational processes and mechanisms by integrating the tenets of planned behavioural theory. A sample comprising 887 valid questionnaires was gathered from middle school, high school, and college students. Subsequently, a structural equation modelling approach, integrating regression and factor analysis, was employed to validate the initial model and associated hypotheses. This study utilized a quantitative research methodology along with a cross-sectional research design. Empirical investigation confirmed six hypotheses derived from the study. Notably, four evolutionary motives—namely, the inclination to avoid harm, mitigate disease risk, foster group affiliation, and pursue mate acquisition—exerted substantial direct effects on teenagers' intentions towards physical exercise. Moreover, these motives also demonstrated indirect impacts on teenagers' physical exercise intentions through subjective norms, attitudes, and perceived control over their physical exercise behaviour. Adolescents' engagement in physical exercise is shaped not solely by superficial factors and external stimuli but is also propelled by intrinsic motives rooted in evolutionary and natural selection mechanisms. An evolutionary perspective sheds light on the nuanced understanding of adolescents' physical exercise, consolidating disparate research on exercise motivation. Building upon this understanding, governmental bodies and educational institutions can devise novel policies and initiatives to foster physical activity among youth, facilitating the maintenance of robust physical health alongside educational pursuits.

The advent of cinema brought with it its use as a propaganda device with which to transmit ideals and doctrines. As a result, newsreels and cinema documentaries were born with the aim of showing the «most relevant» news of the country and abroad, the former with a shorter duration. In this study, the Spanish NO-DO and «Sucesos Argentinos» are used as primary sources to interpret the images and imaginaries that were projected between 1943 and 1955 on female physical culture. The intention is to understand the official discourse of both political regimes on what Argentinean and Spanish society should be like, especially by questioning those meanings about women. In total, 69 issues of NO-DO and 14 editions of «Sucesos Argentinos» have been found which aim to show female physical culture in this period. The female physical culture shown in both newsreels was aimed at strengthening women’s bodies so that they could carry out their «natural functions» (mother, wife, housewife), as well as highlighting their «inferiority» in relation to men through lower impact activities and the homogenization of bodies through clothing, and the performance of the same exercises in synchrony. And all this in countries with different regimes, but which, in the end, coincided.
