The purpose of this study was to examine the classification experiences (perspectives and reflections) of paraswimmers. Classification provides a structure for parasport, with the goal of reducing the impact of impairment on the outcome of competition. Guided by interpretive description, nine paraswimmers ranging in swimming experience and sport class were interviewed. Reflective notes were also collected. Transcribed interviews were analyzed inductively, followed by a deductive analysis using Nordenfelt’s dignity framework. Three themes represent the findings: access, diversity, and (un)certainty. Despite several positive experiences, paraswimmers also discussed inconsistencies in the process leading them to question competition fairness and classification accuracy. These findings suggest that continued efforts to improve the classification system are required. In addition, paraswimmers and their allies (e.g., coaches) require more information about the classification process to better understand the outcomes and to effectively advocate for their needs.

Physical activities provide fundamental benefits to children’s health and well-being. They are vital for development and healthy life, but participation of children with visual impairment is limited. Herein, the authors report results of a 16-wk yoga program, evaluating its effects on physical fitness in children with visual impairment. Eighty-three children age 9–16 years (12.37 ± 2.19) participated in a 2-arm, single-blind wait-list-controlled study at a residential school in south India. Participants (yoga group 41, controls 42) were assessed on muscle strength, flexibility, endurance, coordination, and respiratory health. Significant improvements in physical fitness were observed after the yoga intervention (Group × Time interactions for right-hand grip strength, p < .001; sit-up, p < .001; sit and reach, p < .001; bilateral plate tapping, p < .001; and peak expiratory flow rate, p < .001). Left-hand grip strength showed main effects of time, although there were no Group × Time interactions. Results demonstrate yoga’s ability to improve a wide range of physical variables in children with visual impairment.

Background: Little is known about variation in meeting the 24-Hour Movement Guidelines (including physical activity [PA], sleep, and screen time [ST]) in early childhood. The aim was to evaluate sociodemographic differences in meeting the 24-Hour Movement Guidelines. Methods: Parents of 3–4 year old children reported sociodemographic information and ST. Sleep and PA were measured using accelerometry, and height and weight were objectively measured. The 24-Hour Movement Guidelines include daily PA (total PA: ≥3 h; including ≥1 h of moderate to vigorous), sleep (10–13 h), and ST (≤1 h). Meeting guidelines by age, sex, race, poverty level, and weight status were assessed using chi-square and linear regression models. Results: Of 107 children, 57% were white and 26% lived in households at or below the poverty level. Most children met the PA (91.5%) and sleep (86.9%) guidelines, but few met ST (14.0%) or all 3 (11.3%) guidelines. African American children and children who lived at or below the poverty level were less likely to meet the sleep, ST, and all 3 guidelines compared with others (P < .01 for all). There were no other differences. Conclusion: These results suggest future interventions should focus on reducing differences in movement, namely in sleep and ST.

Occupational socialization theory has been used to understand the recruitment, education, and socialization of physical education teachers for nearly 40 yr. It has, however, only recently been applied to the study of adapted physical education teachers. The purpose of this descriptive case study was to understand the socialization of preservice teachers in an adapted physical education teacher education graduate-level program. Participants included 17 purposefully selected preservice teachers (5 male and 12 female) enrolled in a yearlong graduate-level adapted physical education teacher education program. Qualitative data were collected using interviews, reflective journaling, and field notes taken during teaching and coursework observations. Data analysis resulted in the construction of 3 themes: overcoming contextual challenges to meet learners’ needs, the importance of field-based teacher education, and coping with the challenges of marginalization. The discussion connects to and advances occupational socialization theory in adapted physical education and suggests that professional socialization may have a more profound influence on preservice adapted physical education teachers than on their physical education counterparts.

Investigation of minor league demand is scant relative to major leagues, particularly at the game level. This presents not only a contextual gap in the research, but also a conceptual one related to demand externalities. Minor League Baseball differs from major professional leagues in that gate revenue sharing is not a fixture in league policy, and talent investment decisions are made by the parent club. Nonetheless, it may be the case that a host club benefits from characteristics of its opponent. Econometric examination of over 31,000 minor league games across multiple leagues and seasons finds proximity to an opponent’s major league parent team increases attendance. Although the authors find evidence of increased demand for a top prospect from the home club, the presence of visiting top prospects is not associated with changes in attendance, prompting the question as to whether effective marketing efforts in this regard would increase home club revenues.

Sport event volunteers have predominantly been examined in able-bodied events using quantitative methods. Studies examining the volunteer experience have focused on its relationship with different constructs, resulting in a siloed body of literature in which a holistic understanding of the volunteer experience remains poor. The purpose of this study was to explore the relationships between key constructs (satisfaction, motivation, commitment, and sense of community) and the first author’s (E.L. Lachance) volunteer experience in a para-sport event. The analysis of the narrative using a volunteer experience conceptual framework composed of the key volunteer constructs identified two themes: (a) the power of sense of community and (b) the volunteer role as a source of dissatisfaction. Contributions include the volunteer experience conceptual framework and the relationships between the four constructs and the volunteer experience. Event managers should implement strategies to create a strong sense of community to enhance their volunteers’ experience.

Background: The purpose of this study was to examine the accuracy of heart rate (HR) and energy expenditure (EE) estimated by the Apple Watch Series 1 worn both on the wrist and the upper arm. Methods: Thirty healthy, young adults (15 females) wore the two monitors while participating in a maximal exercise test. Criterion measures were obtained from the Parvo Medics TrueOne 2400 Metabolic Cart and an electrocardiograph. Results: The HR estimations of the arm-worn (AW) Apple Watch had the highest agreement with the electrocardiogram, with mean absolute percent error (MAPE) of <2.5% for the entire sample, for males, and for females, at all exercise intensities. The HR estimations of the wrist-worn Apple Watch had MAPEs ranging from 3.61% (females at very light intensity) to 14.97% (males at very vigorous intensity). When estimating EE for total exercise bout in the entire sample, the arm-worn Apple Watch overestimated EE, with a MAPE of 39.63%, whereas the wrist-worn underestimated EE, with a MAPE of 32.28%. Both the arm- and wrist-worn overestimated EE for females and underestimated EE for males. Conclusion: Wearing the Apple Watch Series 1 on the upper arm versus the wrist improves the MAPE for HR estimations, but does not improve MAPE for the EE calculations when compared to a criterion measure.

Purpose: This purpose of this study was to validate consumer-based and research-grade PA monitors for step counting and Calorie expenditure during treadmill walking. Methods: Participants (n = 40, 24 in second trimester and 16 in third trimester) completed five 2-minute walking activities (1.5–3.5 miles/hour in 0.5 mile/hour increments) while wearing five PA monitors (right hip: ActiGraph Link [AG]; left hip: Omron HJ-720 [OM]; left front pants pocket: New Lifestyles NL 2000 [NL]; non-dominant wrist: Fitbit Flex [FF]; right ankle: StepWatch [SW]). Mean absolute percent error (MAPE) was used to determine device accuracy for step counting (all monitors) and Calorie expenditure (AG with Freedson equations and FF) compared to criterion measures (hand tally for steps, indirect Calorimetry for Calories). Results: For step counting, the SW had MAPE ≤ 10% at all walking speeds, and the OM and NL had MAPE ≤ 10% for all speeds but 1.5 miles/hour. The AG had MAPE ≤ 10% for only 3.0–3.5 miles/hour speeds, and the FF had high MAPE for all speeds. For Calories, the FF and AG had MAPE > 10% for all speeds, with the FF overestimating Calories expended. Trimester did not affect PA monitor accuracy for step counting but did affect accuracy for Calorie expenditure. Conclusion: The ankle-worn SW and hip-worn OM had high accuracy for measuring step counts at all treadmill walking speeds, whereas the NL had high accuracy for speeds ≥2.0 miles/hour. Conversely, the monitors tested for Calorie expenditure have poor accuracy and should be interpreted cautiously for walking behavior.
