The authors examined whether accelerometer-based free-living walking differs between those reporting walking modifications or perceiving walking difficulty versus those with no difficulty. Community-dwelling 75-, 80-, or 85-year-old people (N = 479) wore accelerometers continuously for 3–7 days, and reported whether they perceived no difficulties, used walking modifications, or perceived difficulties walking 2 km. Daily walking minutes, walking bouts, walking bout intensity and duration, and activity fragmentation were calculated from accelerometer recordings, and cut points for increased risk for perceiving walking difficulties were calculated using receiver operating characteristic analysis. The authors’ analyses showed that accumulating ≤83.1 daily walking minutes and walking bouts duration ≤47.8 s increased the likelihood of reporting walking modifications and difficulties. Accumulating walking bouts ≤99.4 per day, having walking bouts ≤0.119 g intensity, and ≥0.257 active to sedentary transition probability fragmented activity pattern were associated only with perceiving walking difficulties. The findings suggest that older people’s accelerometer-based free-living walking reflects their self-reported walking capability.

I adopt an autobiographical approach to chronicle the contexts, experiences, and individuals that shaped my academic and career choices, which resulted in finding kinesiology and, specifically, sport and exercise psychology. Consistent with the developmental perspective I employ in my research and practical applications, I trace my life’s work in youth development through sport using transitional career stages. My academic path has been strongly influenced by hardworking and caring mentors and a commitment to balancing theoretical knowledge, applied research, and professional practice. Based on my many years in higher education, I conclude with some reflections on the future of kinesiology given past and present trends in the field.

This article is organized around the idea that a person can be a part of kinesiology without being in kinesiology. Trained as a sociologist and never having a faculty appointment outside of a sociology department, I am an outsider in kinesiology. However, my participation in kinesiology and relationships with scholars in kinesiology departments have fostered my professional growth and my appreciation of interdisciplinary approaches to studying sports, physical activities, and the moving human body. The knowledge produced by scholars in kinesiology subdisciplines has provided a framework for situating and assessing my research, teaching, and professional service as a sociologist. The latter half of this article focuses on changes in higher education and how they are likely to negatively impact the social sciences and humanities subdisciplines in kinesiology. The survival of these subdisciplines will depend, in part, on how leaders in the field respond to the question, Kinesiology for whom?

Background: Low-income adolescents’ physical activity (PA) levels fall below current recommendations. Perceived barriers to physical activity (PBPA) are likely significant predictors of PA levels; however, valid and reliable measures to assess PA barriers are lacking. This manuscript describes the development of the PBPA Survey for Low-Income Adolescents. Methods: A mixed-method approach was used. Items identified from the literature and revised for clarity and appropriateness (postcognitive interviews) were assessed for test–retest reliability with 74 adolescents using intraclass correlation coefficient. Items demonstrating low intraclass correlation coefficients or floor effects were removed. Both exploratory factor analysis and confirmatory factor analysis analyses (n = 1914 low-income teens) were used to finalize the scale; internal consistency was assessed by Cronbach’s alpha. Concurrent validity was established by correlating the PBPA with the PA questionnaire for adolescents using a Spearman correlation. Results: The exploratory factor analysis yielded a 38-item, 7-factor solution, which was cross-validated by confirmatory factor analysis (comparative-fit index, nonnormed fit index = .90). The scale’s Cronbach’s alpha was .94, with subscales ranging from .70 to .88. The PBPA Survey for Low-Income Adolescents’ concurrent validity was supported by a negative PA questionnaire for adolescents’ correlation values. Conclusion: The PBPA Survey for Low-Income Adolescents can be used to better understand the relationship between PBPA among low-income teens. Further research is warranted to validate the scale with other adolescent subgroups.

Rainer Martens

Learn how sport influenced Rainer Martens’s life and his epiphany to become a physical educator and coach, which led him to study sport psychology. The author briefly recounts his work in sport psychology and coaching education. Next, the author describes how he stumbled into publishing, founding Human Kinetics, and describes how this company helped define kinesiology and influence the broad field of physical activity. The author concludes by reporting on his continued involvement in sport and the development of two community centers that focus on sport and physical activity.

As the title of this article suggests, I describe in this essay how my career has been shaped by specific events, such as not knowing the rules of the game I loved and played extensively, and significant mentors, such as the venerable Dr. Earl Zeigler and Dr. Garth Paton. I also explain how I been involved in the birth and growth of the field of sport management. More importantly, I show how the field has shaped my career and has opened up opportunities for me to travel the world in propagating the field around the globe.

This essay addresses four main questions. The first is devoted to how I became interested in the philosophy of sport. The second question concerns how my academic career has evolved over time in line with various developments in the field that privileged certain lines of study over others and which largely marginalized philosophy in particular and the humanities in general. The third question centers on what I take to be my own main contributions to the philosophy of sport and what, if any, impact they may have had on the larger field of kinesiology. Finally, I offer my own brief prognosis of what I think the future has in store for the relationship between sport philosophy and kinesiology.

Purpose: The purpose of this study was to examine the impact of the Coronavirus disease 2019 on male and female anthropometric variables and physical performance. Methods: This study utilized a mixed (time [PRE vs POST], gender [male vs female]) methods design to examine changes in the body mass index and physical fitness performance measures prior to and following closures. Data were collected from 264 third through eighth graders. This sample consisted of 131 males and 133 females. The data was collected through anthropometric (body mass index) and physical performance measures and was analyzed with separate 2 × 2 mixed-factorial analyses of variance (time [PRE, POST] × gender [male, female]). Results: The findings indicated both males and females exhibited mean increases in the body mass index (+10.6%; 18.8–20.8 kg·m−2, P < .001, partial η 2 = .627) and decreases in push-ups (−35.6%; 7.3–4.7 repetitions, P < .001, partial η 2 = .371), sit-ups (−19.4%; 22.7–18.3 repetitions, P < .001, partial η 2 = .420), and the Progressive Aerobic Cardiovascular Endurance Run test (−26.7%; 31.4–22.4 laps, P < .001, partial η 2 = .644) scores from PRE to POST. Conclusion: The results of this study demonstrate that both males and females exhibited significant anthropometric and physical performance losses during the Coronavirus disease 2019 shutdown.

Purpose: To investigate the association between muscular strength and metabolic syndrome (MetS), with a specific focus on the role of weight status, using a nationally representative sample of US youth. Methods: The analysis included 409 boys and 415 girls from the 2011 to 2014 National Health and Nutrition Examination Survey between 12 and 18 years of age. The prevalence of MetS was defined using age- and sex-specific criteria for abdominal obesity, elevated triglycerides, blood pressure, fasting glucose, and low high-density lipoprotein (HDL) cholesterol. Strength was assessed via handgrip dynamometer and expressed as age- and sex-specific z scores of relative strength. Low strength was defined as a relative strength below the 25th percentile. Analyses controlled for age, sex, race/ethnicity, physical activity, and weight status. Results: The sample prevalence of MetS was approximately 5.3%. However, MetS prevalence was 18.5% in overweight/obese youth with low strength. The adjusted odds of MetS were 3.1 (95% confidence interval, 1.5–6.3, P < .001) times higher for overweight/obese youth with low strength versus sufficient strength. Conclusion: Muscular strength is predictive of adolescent MetS, specifically in those with unhealthy weight status. Approximately one in 5 overweight/obese youth with low strength had MetS. These findings highlight the relevance of muscular strength in youth cardiometabolic morbidities.
