Making Meaning of Student Activism: Student Activist and Administrator Perspectives
College campuses have experienced a recent resurgence of student activism, particularly in response to some of President Donald Trump’s executive orders as well as controversial speakers like Ann Coulter and Milo Yiannopoulous. Student activism presents both challenges and opportunities for higher education leaders seeking to engage productively in these often complex and highly charged issues. We conducted a phenomenological study of ten student activists and eight administrators at three universities to examine the meaning and goals they identify in their experience of campus activism. Findings indicated students identify their activist involvement as highly meaningful, especially with regard to what they feel they learn in college. Similarly, findings indicated administrators found their experience with student activists to be highly consequential in terms of both career satisfaction and dissatisfaction. We also found communication differences between student activists and administrators, even on topics where they generally agree. Given the frequently high stakes nature of contemporary student activism, we present recommendations for practice in the context of understanding these communication differences
ASSESSMENT OF LOWER LIMB ASYMMETRY: DIFFERENCES DURING ISOMETRIC AND STRETCH-SHORTENING CYCLE TASKS
Assessment of limb function asymmetry is of interest to practitioners due to its role in return to play guidelines and reported links to injury. Dynamometry is one of the most commonly used methods of assessing muscle function, but the mode of contraction used is different to the stretch-shortening cycles experienced during real-life activities. The aim of this study was to compare measures of limb function asymmetry during isometric and stretch-shortening cycle tasks and investigate agreement between the methods. Different between-limb effect sizes were observed between limbs dependent on test used, with different ranges of asymmetry observed. Agreement between methods was very poor. These results show the importance of assessing asymmetry in a condition that is as similar as possible to the task of interest
PLANTARFLEXOR FORCE PRODUCTION IN ISOMETRIC AND STRETCH-SHORTENING CYCLE TASKS
The ankle joint and its surrounding musculature are vital in sprinting, and recent work has developed a method to isolate the plantarflexor muscle group for analysis of its force-producing capabilities. The aim of this study was to compare values for plantarflexor force obtained using isometric dynamometry and an adapted force sledge in twenty healthy subjects. Results showed low relationships between isometric and dynamic strength measures, probably because the dynamic test utilises a stretch-shortening cycle. No relationship was observed between isometric strength and the sledge foot plate height during the task with a moderate relationship observed between dynamic strength and plate height. This highlights the important role the Achilles tendon plays in dynamic tasks
DO FLEXIBILITY SCREENING TESTS REFLECT JOINT RANGE OF MOTION DURING DYNAMIC TASKS?
The aim of this study was to investigate if ankle joint range of motion (ROM) during a functional screen test was related to ankle ROM and plantarflexor reactive strength index (RSI) during a dynamic task. The three measures were correlated for the dominant and non-dominant legs to identify what relationship, if any, existed between the three measures. Results showed that there was no relationship between the two measures of ROM, and ROM during the sledge task was positively related to plantarflexor RSI. This is in contrast to other work, possibly due to the isolation of the plantarflexor muscles in the sledge task. Interestingly, between-leg relationships were lower in the dynamic task, suggesting increased variability in the movement strategies used or underlying training differences
THE EFFECT OF INCREASED LOADING ON PLANTARFLEXOR FUNCTION DURING A STRETCH-SHORTENING CYCLE TASK
Increasing loading is one of the most common methods used to increase exercise intensity but it is important to consider the influence of the increase on subsequent force output, rate of force development and, in the case of plyometric exercise, contact time. The aim of this study was to investigate the effect of altering loading on plantarflexor force and force production during a fast stretch-shortening cycle task. Results showed load increased force production and contact time and decreased flight time and reactive strength index. These results have important implications for practitioners in determining the optimal method of increasing training intensity in order to avoid negative training effects
PRELIMINARY ANALYSIS OF SLEDGE REACTION FORCES DURING CYCLICAL LOADING OF THE TRICEPS SURAE
To date, no methodology exists that can measure Achilles tendon stiffness in a controlled dynamic situation while simultaneously investigating tendon and joint stiffness interactions. Stiffness refers to the ratio between force and elongation, and the aim of this preliminary study was to establish an analysis protocol for sledge reaction forces during cyclical loading of the triceps surae. Results indicated the magnitude of forces was just under 50% of body weight, which was expected. Removal of the first two trials from analysis reduced standard deviation and 95% confidence interval of plantarflexor force, contact time and contact time-flight time ratio, suggesting this protocol is suitable to ensure data gathered is repeatable and consistent. Future work using inverse dynamics and ultrasound shall provide information on Achilles tendon loading and stiffness
INFLUENCE OF JUMPING MEASURES AND SQUAT 1RM ON SPRINT SPEED IN RUGBY UNION PLAYERS
This study examined the relationship of countermovement (CMJ), squat (SJ), and rebound jumps (RBJ), estimated 1RM back squat (SQ), contact time (CT) and Reactive Strength Index (RSI) for the RBJ to 30 m sprint time of sub-elite, semi-professional Rugby Union players. The results show that with the exception of SQ and CT, all variables were significantly (p .575). The best determinant of predicting 30 m sprint time was RSI. The relationships of SJ, CMJ, and RBJ jump height and RSI to 30 m sprint time suggest that these rapid movements are all common in Rugby Union players. The results show that estimated 1 RM back squat has little influence on sprint performance
Being Wholesaled: An Investigation of Chinese International Students’ Higher Education Experiences
Using academic capitalism as a theoretical foundation, this phenomenological study examined the new study abroad experiences of Chinese college students in six popular English-speaking study destination countries—the U.S., the U.K., Australia, Canada, the Netherlands, and Singapore. Qualitative data collected from 20 interviews indicate some hosting higher education institutions prioritize enrollment growth and neglect recruitment process and student development. Three main findings are 1) delegating recruitment to overseas agencies causes mismatches between host institutions and the Chinese students, 2) Chinese students having insufficient language skills are prone to have a dissatisfied study abroad experience, and 3) high density of student population from one country impedes Chinese students’ integration on campus. Implications for higher educational professionals, students, and faculty are presented
RELIABILITY OF JUMP AND PERFORMANCE MEASURES IN RUGBY UNION PLAYERS
The current study examined the reliability of countermovement (CMJ), squat (SJ), and rebound jumps (RBJ) to sprint and estimated 1RM back squat (SQ) of sub-elite Rugby Union players drawn from two teams of similar competitive level. Comparisons of mean performance on all tests were made via Student t-tests. The three trial reliability of jump height for the SJ, CMJ, RBJ, contact time (CT) and Reactive Strength Index for the RBJ, T-Test agility run (TA-Test), 30 and 36.58 m (40 yd) sprint times were estimated via ICC and ReANOVA. All variables displayed Average measures ICC ≥ .900; and except for the TA-Test, the three trials did not differ from each other. The performance of the two teams was found to be similar on all tests except the 30 m and 40 yd sprint tests. All the studied performance measures could be reliably assessed with one trial, except the TA-test
