No full textInternational Journal of Exercise Science 18(6): 1047-1060, 2025. https://doi.org/10.70252/WWDK4926 Isometric handgrip (IHG) coupled with post-exercise muscular ischemia (PEMI) and the cold pressor test (CPT) have been demonstrated to increase measures of hemodynamics and to reduce vagal tone. However, little is known about how acute resistance exercise (RE) alters these responses. The purpose was to evaluate an acute bout of RE in conjunction with a single- or dual-stressor task on hemodynamics and autonomic modulation in resistance-trained individuals. Ten resistance-trained individuals (Mean ± SD; Age: 23 ± 3 years) completed a single- (SS: IHG + PEMI only) or dual-stressor (DS: IHG + PEMI + CPT) task condition. Before and after the acute RE variables were monitored during five minutes of rest (REST), two minutes of IHG, three minutes of PEMI with or without concurrent CPT (STRESS). Hemodynamics included heart rate (HR), mean arterial pressure (MAP), cardiac output (Q,). stroke volume (SV) and total peripheral resistance (TPR), while autonomic data were measured via heart rate variability and heart rate complexity. There were no significant (p \u3e 0.05) three-way interactions for HR, Q, or TPR. However, there was a significant three-way interaction (p = 0.007) for SV such that SV was significantly increased during STRESS compared to REST in the SS condition but did not change in the DS condition. There were no significant (p \u3e 0.05) interactions for measures of autonomic modulation. These data suggest that young, resistance-trained individuals have a significant cardiac sympathetic reserve and thus a large capacity to handle multiple stressors following acute RE
Confidence in Motion: Building Leadership and Visibility in Exercise Science Careers
No full textSuccess in exercise science and kinesiology requires more than academic excellence or technical skill—it requires confidence, visibility, and the ability to communicate your expertise. In this keynote, WSJ-bestselling author Sheena Yap Chan (The Tao of Self-Confidence, Bridging the Confidence Gap) shares how students can overcome self-doubt, advocate for themselves in research and professional spaces, and step into leadership roles early in their careers. Drawing from her own journey and stories from hundreds of professionals she has interviewed, Sheena will equip students with tools to present research confidently, network authentically, and translate their knowledge into impact. This session inspires the next generation of exercise science leaders to not only excel academically but also become visible voices advancing health and human performance.
Learning Objectives
By the end of this session, students will be able to:
1. Identify confidence barriers that affect how they present their skills, research, and professional goals.
2. Apply visibility strategies—storytelling, presence, and advocacy—in academic and career advancement.
3. Create a personal “Confidence Roadmap” to prepare for graduate school applications, interviews, and professional opportunities
Leveraging the power of groups to promote health and well-being: A social identity approach
No full textDrawing from the social identity approach (Haslam et al., 2018; Turner, 1985; Turner et al., 1987, 1994), this presentation will explore the ways in which our sense of self (i.e., identity) is defined by the groups we belong to (e.g., a team, a club, a profession), and how the power of groups can be leveraged to promote health and well-being. Social identities play a powerful role in shaping our thoughts, emotions, and behaviors. Researchers have found that by harnessing a collective sense of “us” (rather than “I”), we can promote greater uptake and adherence to exercise and other health-related programs, and subsequently improve health and well-being outcomes among inactive and at-risk populations. This presentation will discuss the utility of social identity-informed group-based programs in the promotion of various health behaviors in our communities
Bridging the Gap Between Rehab and Reconditioning
No full textThe transition from rehabilitation to reconditioning remains one of the most critical yet inconsistently managed phases in an athlete’s return-to-play process. While early rehabilitation successfully restores pain-free range of motion and basic strength, many athletes remain ill-prepared for the physical and psychological demands of high-level sport upon medical clearance. The purpose of this presentation is to provide a systematic and performance-driven framework for bridging the gap between rehabilitation and reconditioning, ensuring a smooth continuum from injury to optimal performance. This framework is built around three guiding principles: minimizing time loss, maximizing performance, and ensuring repeatability. Minimizing time loss emphasizes the use of early mobilization, pain-tolerant loading, and progressive off-feet conditioning to maintain physiological readiness during tissue healing. Maximizing performance focuses on purposeful adaptation—targeting range of motion, force production along the strength–speed continuum, power output, and energy system development. Early reintroduction of sport-specific activities and cognitive challenges enhances athlete confidence while preparing the central nervous system for return-to-play demands. Ensuring repeatability involves developing standardized systems, clear stage progressions, and effective communication among multidisciplinary staff to eliminate silos and reinforce collaborative decision-making. Common complications in this transition phase include premature clearance before full tissue healing, compensatory movement patterns, residual strength asymmetries, and athlete apprehension. Addressing these challenges requires a needs-based assessment that accounts for timelines, adaptation goals, and sport- and position-specific demands. The process should also integrate gradual exposure to sport forces—progressing from linear low-speed movements to multidirectional, high-speed, and curvilinear patterns that replicate true match scenarios. A case study of a professional soccer player recovering from a Grade 3B proximal hamstring strain illustrates these principles in practice. The athlete’s plan included criteria-based progressions in fascicle lengthening, eccentric strength restoration, workload tolerance, and maximal velocity exposure, culminating in return to team training and competition within the projected 6–8 week window. Objective metrics such as limb symmetry, workload progression, and sprint speed thresholds guided readiness decisions, while interdisciplinary communication supported a unified approach to reconditioning. Ultimately, bridging the gap between rehab and reconditioning requires clinicians and performance professionals to shift from a symptom-resolution mindset to a performance-restoration mindset. By aligning medical, physical, and performance objectives through measurable criteria and collaborative systems, practitioners can enhance both safety and performance outcomes. This integrated model not only minimizes reinjury risk but also maximizes the athlete’s readiness, resilience, and long-term career sustainability
Mentored to Mastery: Using CUREs to Build Scientific Confidence and Independence in Undergraduate Exercise Science Researchers
No full textCourse Based Undergraduate Research Experiences (CUREs) are a high impact teaching practice in which students engage in mini-research projects guided by a faculty member within a course to answer an original research question with an unknown outcome. CUREs allow for more inclusive participation in undergraduate research while developing inquiry and analysis, collaboration, information literacy, and communication skills. CUREs enhance scientific confidence for students, especially in exercise science where science identity may be low. CUREs are also beneficial to faculty members. Faculty can integrate their teaching and scholarship as well as fine tune their mentoring skills during these experiences. CUREs help students build skill foundations which can be transferred to larger scale, independent undergraduate research projects. Participation in independent research is an opportunity for students to develop skills and abilities valued by employers and graduate and professional programs. This session is a panel discussion designed to introduce students and faculty to the concept of CUREs and highlight how students used their experiences in an Exercise Physiology lab-based CURE to successfully develop and launch independent undergraduate research projects. The panel will be led by a faculty mentor who will discuss the benefits, challenges, and general structure of CUREs as well as how they mentor independent student research. Four undergraduate exercise science students with different career paths and research projects will discuss their experiences with CUREs. Student panelists will discuss what they learned from doing a CURE and how their experiences helped shape their independent research. The students will share advice on facing challenges and working with faculty mentors. The discussion will include tips for students who have access to faculty mentors using CUREs and how students might encourage faculty who already mentor student researchers to use CUREs to help students better prepare for independent research
Effects of Rehabilitative Device on Parkinsonian Gait
No full textInternational Journal of Exercise Science 18(7): 1422-1440, 2025. https://doi.org/10.70252/TGOI6101 Parkinson’s disease (PD) is second in occurrence among neurodegenerative disorders after Alzheimer’s disease and significantly impacts gait and mobility. This research tested the effect of the NewGait rehabilitative device in PD impaired individuals. Twenty individuals with PD participated in this study. Walking gait for three conditions were analyzed: Normal, wearing NewGait and Post-NewGait. Standard spatial and temporal analysis measures as well as nonlinear measures from recurrence quantification were compared to determine any effects of the device on walking gait. NewGait was perceived to be both comfortable to wear as well as resulted in increased ease of movement. Step width was increased while wearing NewGait while step length was unchanged. No differences were found in temporal measures: cadence, stride time and double support time. Wearing NewGait resulted in a slight, but not significant decrease in walking velocity compared to Normal. Post-NewGait gait velocity was increased compared to wearing NewGait. Based only on these standard linear spatiotemporal measures, NewGait is somewhat intrusive for gait Parkinsonian individuals, resulting in a less effective gait. The recurrence-based analysis however, found that compared to Normal, Determinism and Laminarity was increased while wearing NewGait and Post-NewGait. Entropy was also increased while wearing NewGait and there was a tendency towards increased Entropy while walking after wearing NewGait. These results suggest NewGait allows for greater predictability and complexity of the gait pattern with increased dynamic stability than walking without NewGait. Therefore, there is potential for longer-term beneficial effects of NewGait in rehabilitation of Parkinsonian gait
Behavioral Predictors of Glycemic Control in People with Type II Diabetes in the Dominican Republic
No full textThe prevalence of type II diabetes (T2D) has been increasing rapidly in low- and middle-income countries. Previous research in this population found very high physical activity participation. PURPOSE: Explore predictive behavioral variables of fasting blood glucose (FBG) in people with T2D in the Dominican Republic. METHODS: Sixty-five (48 women and 17 men) people with T2D enrolled. FBG was measured using a capillary blood glucose monitor. Yale Physical Activity Survey (YPAS), Pittsburgh Sleep Quality Index, Perceived Stress Scale-10, Global Diet Quality Questionnaire, and Health Related Quality of Life-14 (HRQoL) were administered by a Dominican physician. Bivariate correlations between variables were evaluated. Multiple regression analysis was conducted to evaluate the behavioral predictors of FBG. RESULTS: Participant age was 58 ±12 years, body mass index (BMI) was 28.0 ± 4.5 kg•m-2, and time with T2D diagnosis was 9 ± 7 years. Only 23% were in the target range (80-130 mg/dL) for controlled diabetes. Participants reported 2594 ± 1198 MET•min•week-1 of PA. All but one participant was classified as a poor sleeper. Only 8% followed a Healthy Diet Pattern for prevention of chronic disease, and 32% consumed no fruits or vegetables. Ten participants were classified as having high perceived stress and 53 as moderate stress. HRQoL indicated that 44% were had significantly impaired. The overall regression model was significant (F = 2.79, p = 0.025). Among the predictors, only YPAS was a significant predictor of fasting blood glucose (ß=1.2, p = 0.002). The correlation between PA and FBG was positive (r=0.40, p=0.001). Sleep Quality (p = 0.76), Diet Quality (p = 0.52), Perceived Stress (p = 0.16), and HRQoL (p = 0.47) were not significant predictors. When controlling for age, gender, BMI, and years with T2D, YPAS remained a significant predictor of FBG (ß=0.89, p=0.015). HRQoL was significantly correlated with YPAS (r=0.30, p=0.015) and Sleep Quality (r=-0.37, p=0.003). Diet quality and perceived stress were not correlated with any behavioral variables. CONCLUSION: Despite very high physical activity, most participants had poor glycemic control, sleep quality, and diet. These findings highlight the need for multifaceted interventions addressing multiple lifestyle factors to improve diabetes outcomes in LMIC
