Evidence supporting exercise as a medicine in the prevention and management of chronic disease is indisputable. Created in 2007, Exercise is Medicine® (EIM) aims to make physical activity assessment and promotion a standard in clinical care, connecting health care professionals with qualified exercise professionals to provide evidence-based physical activity resources and programs to everyone of all abilities. Opportunities exist for exercise professionals in several areas within EIM, including exercise referral and prescription, EIM on Campus, and physical activity and EIM education. Connections between EIM and kinesiology and the need for exercise professionals to contribute to the EIM evidence are discussed.

Promoting the success of all students is one of four institutional goals at Texas State University. Retention and graduation rates provide information regarding the academic progress and success of specific student cohorts. To gain a deeper insight into student success within the undergraduate kinesiology/exercise and sports science program at Texas State University, an equity audit was conducted during the fall 2019 academic semester. An equity audit provides a lens to critically examine institutional data to identify inequities in academic programs and student achievement based on specific variables, such as gender, age, race, and socioeconomic status. This article provides a model for conducting an equity audit in kinesiology/exercise and sports science programs, reports the findings, and highlights strategic actions implemented to combat inequities in student success.

Purpose: The Nordic hamstring exercise (NHE) has been shown to considerably reduce hamstring injuries among soccer players. However, as the load in the NHE is the person’s own bodyweight, it is a very heavy exercise and difficult to individualize. The flywheel inertial leg curl (FLC) could be an alternative since the eccentric overload is based on the amount of work produced in the concentric movement. Therefore, the primary aim of this study was to compare the activation in the hamstrings at long muscle lengths in the NHE and the FLC in amateur soccer players. Methods: Fifteen male amateur soccer players performed 5 repetitions in each exercise in a randomized and counterbalanced order. The concentric and eccentric movements were divided into lower and upper phases. Surface EMG was measured distally, proximally, and in the middle, at both muscles. Results: In the lower phase in the eccentric movement, there were no significant differences between the 2 exercises (P = .101–.826). In the lower concentric movement, the FLC led to higher activation in all parts of both the biceps femoris (31%–52%, P < .001) and the semitendinosus (20%–35%, P = .001–.023). Conclusion: Both exercises activated the hamstrings similarly at long muscle lengths during eccentric contractions (Nordic hamstring, nonsignificantly higher). However, when performing concentric contractions, the FLC induced higher activations. Therefore, the FLC could be a useful alternative to the NHE and particularly suitable for weaker athletes before progressing to NHE.

This study examined how different types of social interaction and competitive information in exergaming affect older adults’ motivation and attitude toward playing exergames. A 2 (time: pre- vs. posttest) × 3 (social interaction: play alone vs. play with peer vs. play with youth) × 2 (competition: competition informed vs. noncompetition informed) mixed experiment was conducted with 319 Singaporean older adults over 6 weeks through a three-way analysis of variance. Social interaction was found to significantly affect the changes of extrinsic motivation over time, while competitive information affected intrinsic motivation significantly. The results showed significant three-way interaction effects between time, social interaction, and competitive information on older adults’ extrinsic and intrinsic motivations. The changes of attitude over time were not affected by either social interaction or competitive information. The findings contribute to aging research and advance the knowledge of potential factors that promote the effective implementation of exergames for community older adults.

Purpose: To evaluate the reliability of new change-of-direction-economy tests (assessing energetic efficiency when performing continuous shuttle runs) compared with common running-economy tests in soccer players Methods: Sixteen subelite, male soccer players were recruited to perform a testing battery involving running economy (RE), 10-m shuttle-running economy (SRE10), and 20-m shuttle-running economy (SRE20) at 8.4 km·h−1 mean speed on 2 different days within 48 hours. SRE10 and SRE20 consisted of continuous shuttle runs interspersed with 180° directional changes. During the RE, SRE20, and SRE10 tests, respiratory exchange ratio and oxygen uptake were collected and used to calculate the movement-economy values over any running condition as oxygen cost and energetic cost. The secondary variables (carbon dioxide production, heart rate, minute ventilation, and blood lactate) were also monitored during all tests. Results: Depending on expression (oxygen cost or energetic cost), reliability was established for RE (CV: 5.5%–5.8%; ICC = .77–.88), SRE10 (CV: 3.5%–3.8%; ICC = .78–.96), and SRE20 (CV: 3.5%–3.8%; ICC = .66–.94). All secondary physiological variables reported good reliability (CV < 10%), except for blood lactate (CV < 35.8). The RE, SRE10, and SRE20 tests show good reliability in soccer players, whereas blood lactate has the highest variability among physiological variables during the economy tests. Conclusion: The assessment of change-of-direction economy through performing 20- and 10-m shuttle runs is reliable and can be applied to evaluate soccer players’ energetic movement efficiency under more soccer-specific running conditions.

Purpose: Currently, it is unclear which physical characteristics may underpin the change of direction deficit (COD-D). This investigation sought to determine if momentum, speed-, and jump-based measures may explain variance in COD-D. Methods: Seventeen males from a professional soccer academy (age, 16.76 [0.75] y; height, 1.80 [0.06] m; body mass, 72.38 [9.57] kg) performed 505 tests on both legs, a 40-m sprint, and single-leg countermovement and drop jumps. Results: The regression analyses did not reveal any significant predictors for COD-D on either leg. “Large” relationships were reported between the COD-D and 505 time on both limbs (r = .65 to .69; P < .01), but COD-D was not associated with linear momentum, speed-, or jump-based performances. When the cohort was median split by COD-D, the effect sizes suggested that the subgroup with the smaller COD-D was 5% faster in the 505 test (d = −1.24; P < .001) but 4% slower over 0–10 m (d = 0.79; P = .33) and carried 11% less momentum (d = −0.81; P = .17). Conclusion: Individual variance in COD-D may not be explained by speed- and jump-based performance measures within academy soccer players. However, when grouping athletes by COD-D, faster athletes with greater momentum are likely to display a larger COD-D. It may, therefore, be prudent to recommend more eccentric-biased or technically focused COD training in such athletes and for coaches to view the COD action as a specific skill that may not be represented by performance time in a COD test.

The benefits, barriers, and methodologies of the enhancement of undergraduate research have been widely studied in higher education. However, there are limited studies on undergraduate research in the field of kinesiology. The previous studies centered around student or faculty evaluation of existing curricular or extracurricular undergraduate research programs. The extent to which these studies may inform a kinesiology department that does not have an established undergraduate research curriculum or program is questionable. This article provides a general overview of existing undergraduate research enhancement programs in other universities, presents a recent research study on perceptions of undergraduate research in exercise and sports science students at Texas State University, and offers future recommendations on enhancing undergraduate research in kinesiology.

The goal of university instructional physical activity programs (IPAPs) is to provide quality instruction through best practices to encourage college students to lead healthy and physically active lifestyles. As IPAPs have continued to decline due to enrollment and budgetary concerns, the importance of quality and sustainability has become particularly paramount. Furthermore, it is imperative to the existence of IPAPs that we strive to learn and share with each other in order to independently survive, but more essentially to flourish collectively, as we are better together. In our varied experience, while some IPAPs face unique challenges, many obstacles are common, regardless of institution size and composition. This paper will offer the perspectives of four strikingly different colleges and universities in their quest to navigate challenges in delivery, maintain and support quality instruction, and advocate for IPAPs.

Programs that provide student research experiences at the undergraduate level are an impactful means of recruiting and preparing students for graduate academic programs. Notably, such programs, when combined with faculty mentorship, exposure to graduate-school-level academic curricula, and socialization experiences, are considered crucial to the effective recruitment and retention of students from diverse cultural backgrounds into science, technology, engineering, and mathematics (STEM)-oriented graduate academic programs. This work outlines the strategic efforts of Auburn University’s School of Kinesiology to enhance its graduate student diversity recruitment and retention processes. Highlighted are the School of Kinesiology’s goals and guiding principles related to diversity and inclusion initiatives. A detailed description of the centerpiece of this effort, the Future Scholars-Summer Research Bridge Program, is provided. Additionally, related Future Scholars-Summer Research Bridge Program topics are discussed, including securing donor support, aligning the program with institutional strategic goals, forming institutional or academic program partnerships, and addressing administrative and logistical challenges.
