Background: A combination of walking, other moderate physical activity, and vigorous physical activity is recommended for achieving good health. Vigorous activity has unique health benefits but may be less accessible to disadvantaged people. To reduce health inequity, we need to understand the differences in physical activity participation among socioeconomic subgroups and whether this is changing over time. Methods: Data from the 2002 to 2015 Adult New South Wales Population Health Surveys (164,652 responses) were analyzed to investigate trends in walking, moderate and vigorous physical activity participation by socioeconomic status as measured by educational attainment. Analysis used age- and sex-adjusted multivariable linear models that accounted for complex survey design. Results: In 2002, the highest socioeconomic group spent 18.5 (95% confidence interval, 8.2–28.8) minutes per week more than the lowest socioeconomic group being vigorously active. By 2015, this gap had steadily increased to 41.4 (95% confidence interval, 27.6–55.1) minutes per week. Inequity between groups was also found for duration of moderate activity but not for time spent walking. Conclusions: Low participation in vigorous activity in the lowest socioeconomic group is likely driving increasing inequities in physical activity and widening participation gaps over time. Barriers preventing the most disadvantaged people in New South Wales from engaging in vigorous activity should be addressed urgently.

Purpose: To examine potential differences in internal and external workload variables between playing positions and between training drills and games within an elite netball team during training and competition. Methods: Nine elite female netballers were monitored during 15 games and all training sessions over 28 weeks. Workload variables assessed were relative PlayerLoad (PL per minute), accelerations, decelerations, jumps, changes of direction, high-intensity events, medium-intensity events, low-intensity events, PL in a forward direction, PL in a sideways direction, PL in a vertical direction, and summated heart-rate zones using heart-rate monitors and inertial measurement units. Results: Conditioning and match play during training were the only drills that matched or exceeded game workloads. Workloads during small-sided games were lower than game workloads for all variables. In games, goalkeeper, goal attack, and goal shooter had a greater frequency of jumps compared with other positions. Midcourt positions had a greater frequency of low-intensity events in a game. Conclusions: Workloads during small-sided games were lower than game workloads across all external and internal variables; therefore, netball staff should modify these small-sided games if they wish them to develop game-based qualities. Specific game workload variables indicate that there are differences within some positional groups; coaches need to be aware that positional groupings may fail to account for differences in workload between individual playing positions.

Purpose: To examine the concurrent and construct validity of numerically blinded ratings of perceived exertion (RPEs). Methods: A total of 30 elite male youth soccer players (age 16.7 [0.5] y) were monitored during training and matches over a 17-wk in-season period. The players’ external loads were determined via raw 10-Hz global positioning system. Heart rate (HR) was collected continuously and expressed as Bannister and Edwards training impulses, and minutes >80% of the players predetermined the maximum HR by the Yo-Yo Intermittent Recovery Test Level 1. RPE was collected confidentially 10 to 15 min after training/matches using 2 methods: (1) a traditional verbal response to the 0 to 100 category-ratio “centiMax” scale (RPE) and (2) numerically blinded RPE centiMax scale (RPEblind) with the response selected manually via a 5 × 7-in tablet “slider.” The RPE and RPEblind were divided by 10 and multiplied by the duration to derive the sessional RPE. Linear mixed models compared ratings, and within-subject repeated-measures correlations assessed the sessional RPE versus HR and external load associations. Results: There were no differences between the RPE and RPEblind (0.19; 95% confidence intervals, −0.59 to 0.20 au, P = .326) or their session values (13.5; 95% confidence intervals, −17.0 to 44.0 au, P = .386), and the ratings were nearly perfectly correlated (r = .96). The associations between the sessional RPE versus HR and external load metrics were large to very large (r = .65–.81), with no differences between the RPE methods (P ≥ .50). The RPEblind also reduced verbal anchor clustering and integer bias by 11% and 50%, respectively. Conclusions: RPEblind demonstrated concurrent and construct validity versus the traditional method, and may be used in situations where practitioners have concerns regarding the authenticity of athlete ratings.

At specific moments in history, women publicly entered the masculine realm of baseball to advance female suffrage in the United States. Girls and women took to the field in the nineteenth century, enjoying newfound bodily freedoms and disrupting Victorian constraints. While their performances may not have always translated into explicit suffrage activism, their athleticism demonstrated strength at a time when many people used women’s supposed weakness as an argument against their political enfranchisement. However, as the popularity of baseball increased at the turn of the century, the number of female ballplayers decreased. Activism in the sport therefore changed. In the mid-1910s, suffragists advertised at men’s baseball games. The women recognized the value of promoting suffrage through sport; yet, they also acknowledged that by entering ballparks, they entered a male space. Suffragists therefore exhibited conventional White gender norms to avoid aggrieving male voters. Women’s different engagements with baseball, as either players or spectators, had varying consequences for women’s political and sporting emancipation. Women’s physical activism in baseball demonstrated female prowess and strength in sport, but only abstractly advanced women’s political rights; suffragists’ promotional efforts through men’s baseball more directly influenced the eventual passage of the Nineteenth Amendment, but their actions supported women’s position on the sidelines.
This study explored the daily life physical activity (PA) experiences of 11 adolescent girls living in a rural community in the Northwest of the United States. This qualitative study employed visual methods to explore adolescent girls’ PA experiences in their daily lives. Specifically, this study used visual diaries and photo-elicitation interviews to capture girls’ PA experiences. Data from this study revealed two distinct PA patterns among the 11 participants: casual movers and sporty girls. Casual movers have a much less structured approach to PA. They engage in a wide variety of PA types—mostly individual forms of PA and PA geared towards recreation. They describe fun, enjoyment, and task mastery as their main motivations to be physically active. Casual movers often engage in PA with family members and are compelled to be active outdoors and in their homes or neighborhoods. In contrast, all five sporty girls belong to competitive sports teams and have a more structured PA routine. They seek performance improvement and have high perceptions of physical competence. Sporty girls value being active with their teammates and receive strong support from their families in the form of encouragement, role modeling, and financial/structural assistance. Sporty girls feel confident being active in their schools’ fields, courts, and gymnasiums, but also appreciate the outdoors environment. Findings from this study support the need for schools to increase access to PA opportunities that are not focused on skill or fitness performance, thus appealing to casual movers’ approach to physical movement.

This study applies “Europeanness” to the analysis of internationalization in the sport management labor market and which changes this trend necessitates for sport management curricula. The authors employed an analysis of 30 semistructured interviews with key informants from Germany, Norway, and Spain. The results reveal various effects of internationalization on the sport sector and highlight the richness and diversity in the three countries. Sport management graduates need to possess a diverse set of competencies for successfully starting their careers. In addition to subject-specific knowledge, generic competencies such as the ability to work in a team, being able to communicate in diverse languages, and having intercultural skills are important. The article discusses knowledge of international sport organizations, their governance, global trends, and intercultural and language competencies, as well as international sport event management as identified themes and proposes specific curriculum changes to promote educational outcomes of sport management programs.

Purpose: To compare the concurrent validity of session-rating of perceived exertion (sRPE) workload determined face-to-face and via an online application in basketball players. Methods: Sixteen semiprofessional, male basketball players (21.8 [4.3] y, 191.2 [9.2] cm, 85.0 [15.7] kg) were monitored during all training sessions across the 2018 (8 players) and 2019 (11 players) seasons in a state-level Australian league. Workload was reported as accumulated PlayerLoad (PL), summated-heart-rate-zones (SHRZ) workload, and sRPE. During the 2018 season, rating of perceived exertion (RPE) was determined following each session via individualized face-to-face reporting. During the 2019 season, RPE was obtained following each session via a phone-based, online application. Repeated-measures correlations with 95% confidence intervals were used to determine the relationships between sRPE collected using each method and other workload measures (PL and SHRZ) as indicators of concurrent validity. Results: Although all correlations were significant (P < .05), sRPE obtained using face-to-face reporting demonstrated stronger relationships with PL (r = .69 [.07], large) and SHRZ (r = .74 [.06], very large) compared with the online application (r = .29 [.25], small [PL] and r = .34 [.22], moderate [SHRZ]). Conclusions: Concurrent validity of sRPE workload was stronger when players reported RPE in an individualized, face-to-face manner compared with using a phone-based online application. Given the weaker relationships with other workload measures, basketball practitioners should be cautious when using player training workloads predicated on RPE obtained via online applications.

Context: Mulligan’s Mobilization with Movement (MWM) is a common intervention used to address dorsiflexion range of motion (DFROM) impairments. However, the treatment dosage of MWMs varies within the literature. Objective: The aim of this study was to examine the effect of serial MWM application on DFROM. Design: Repeated-measures cohort. Setting: A Midwestern University and the surrounding community. Participants: A total of 18 adults (13 females; age = 29 [12.87] y; DFROM = 30.26° [4.60°]) with decrease dorsiflexion (<40°) participated. Inclusion criteria consisted of a history of ≥1 ankle sprain, ≥18 years old, no lower-extremity injury in the last 6 months, and no history of foot/ankle surgery. Intervention: Participants completed a single data collection session consisting of 10 individual sets of MWMs. Main Outcome Measures: DFROM was taken at baseline and immediately after each intervention set (post 1, post 2, … post 10). DFROM was measured with a digital inclinometer on the anterior aspect of the tibia during the weight-bearing lunge test with the knee straight and knee bent. Analysis of variances examined DFROM changes over time. Post hoc analysis evaluated sequential pairwise comparisons and changes from baseline at each time point. Results: Analysis of variance results indicated a significant time main effect for weight-bearing lunge test with knee bent (P < .001) and a nonsignificant effect for weight-bearing lunge test with knee straight (P < .924). Post hoc analysis indicated improvements in the weight-bearing lunge test with knee bent at each timepoint compared with baseline (P < .005). Post 2 improved compared with post 1 (P = .027). No other pairwise sequential comparisons were significant (P > .417). Conclusions: MWMs significantly improved acute knee bent DFROM and indicated that after 2 sets of MWMs, no further DFROM improvements were identified. Future research should investigate the lasting effects of DFROM improvements with variable MWM dosages.

Singaporean footballer Ben Davis applied for deferment from national service (NS) in order to pursue his dream of playing in the English Premier League. However, his deferment request was rejected by the Ministry of Defense, and there was a sizable national debate on whether Davis should be granted the deferment. The study sought to use the Ben Davis saga as a case study to provide an exploration of public opinion toward various issues relating to sport and society. A total of 14,093 comments were extracted from various news sources on Facebook, and a randomized sample of 1,875 comments was used for the final analysis. The constant comparative methodology was used to conduct a thematic analysis of the comments. The analysis produced four higher order themes: (a) sport in Singapore, (b) role and relevance of NS, (c) national interest versus individual choice, and (d) perception of new citizens and foreign talent.

People developing transient low back pain during standing have altered control of their spine and hips during standing tasks, but the transfer of these responses to other tasks has not been assessed. This study used video fluoroscopy to assess lumbar spine intervertebral kinematics of people who do and do not develop standing-induced low back pain during a seated chair-tilting task. A total of 9 females and 8 males were categorized as pain developers (5 females and 3 males) or nonpain developers (4 females and 5 males) using a 2-hour standing exposure; pain developers reported transient low back pain and nonpain developers did not. Participants were imaged with sagittal plane fluoroscopy at 25 Hz while cyclically tilting their pelvises anteriorly and posteriorly on an unstable chair. Intervertebral angles, relative contributions, and anterior–posterior translations were measured for the L3/L4, L4/L5, and L5/S1 joints and compared between sexes, pain groups, joints, and tilting directions. Female pain developers experienced more extension in their L5/S1 joints in both tilting directions compared with female nonpain developers, a finding not present in males. The specificity in intervertebral kinematics to sex-pain group combinations suggests that these subgroups of pain developers and nonpain developers may implement different control strategies.
