Influence Of Prior Alkalosis Or Acidosis On Physiological Responses During Passive Hyperthermia, Jacky Soo, Shernise Ng, Chris Abbiss, Olivier Girard, Mohammed Ihsan
Research outputs 2022 to 2026
This study manipulated the blood pH of participants to be mildly acidic or basic prior to passive hyperthermia to examine its effects on thermoregulatory and chemo-regulatory responses, including ventilatory parameters, rectal temperature (Tre) and thermal perception. Twelve healthy males attended three experimental sessions in a double-blind, randomised, counterbalanced design. Passive hyperthermia was induced by hot water immersion at 40°C following the consumption of corn starch (placebo; PLA), ammonium chloride (AC) or sodium bicarbonate (SB). Compared with PLA, SB consumption increased blood pH and HCO3−, whilst AC decreased both blood pH and HCO3− (all P < 0.001). Specifically, minute ventilation was unchanged following SB (11.0 ± 3.7 L min−1) but …

Research outputs 2022 to 2026
The aim of this study was to determine whether extending traditional calf-raise resistance training sets with partial-range-of-motion (ROM) repetitions in the more dorsiflexed ROM enhances muscular hypertrophy. Sixteen untrained men (25.0±1.7y) completed 10 weeks of unilateral standing calf-raise training (2×/wk) in a within-subject design: one leg performed traditional 10-14RM sets to full-ROM momentary failure (MF; 4-6 sets/session) and the other leg performed half as many sets to full-ROM failure followed by partial-ROM repetitions to a second failure in the more dorsiflexed ROM (PBF; 2-3 sets/session). Total volume-load was equated between conditions; repetitions were counted the same way regardless of the …

Research outputs 2022 to 2026
This study examined the effects of ischemic preconditioning (IPC) on physical performance, considering the influence of timing, warm-up (WU), participant characteristics, and IPC protocols structure. A total of 90 trials (1,439 participants) were retrieved from three databases and assessed using PICOS criteria. Multilevel meta-analyses with cluster-robust variance adjustments were conducted to calculate pooled effect sizes (Hedge’s g). Risk of bias and certainty of evidence were assessed using the RoB 2 tool and GRADE framework. IPC produced a trivial but significant improvement in physical performance (g = 0.13, P < 0.01), which persisted after excluding SHAM effects (g = 0.10; P < 0.01). Significant improvements were observed for maximum repetitions, time to failure, and power output, but not for jump ability, strength, or oxygen uptake. Comparable benefits were found for anaerobic (g = 0.15) and aerobic (g = 0.10) exercise, with greater effects in males and less-trained participants. Performance was further enhanced when IPC was followed by WU (g = 0.16), with the optimal IPC-to-WU interval being ~42 minutes. Without WU, the effective IPC window narrowed to 6–7 minutes. In practice, IPC can enhance physical performance, independently of sham effects, moderated by sex, training level, and WU. For competition or testing, the most effective strategy appears to be 3 or 4 × 5-min IPC protocol, followed by a 42-min interval, standardized warm-up, and endurance testing. For mechanistic studies, WU should be excluded, and testing conducted 6-7 minutes post-IPC. Future research should target women, middle-aged individuals, and elite athletes.

Research outputs 2022 to 2026
In this Current Opinion, we revisit key terminological distinctions in sports sciences, emphasizing the implications of conflating related but distinct concepts, particularly range of motion (ROM) versus flexibility and flexibility training versus stretching. While often used interchangeably, these terms represent nuanced constructs with distinct physiological and practical implications. ROM encompasses both modifiable (e.g., soft tissue extensibility, neural control) and non-modifiable factors (e.g., bone structure), whereas flexibility is only one of several trainable components of ROM, largely referring to the extensibility of periarticular soft tissues. Misunderstanding these distinctions risks erroneous assessments and inappropriate exercise prescriptions. We also challenge the common practice …

Research outputs 2022 to 2026
Historically, sport science and medicine researchers have had difficulty obtaining adequate sample sizes, limiting their ability to make accurate generalizations to populations of athletes. To move towards better and more generalizable research, sport could look to other fields of research, and draw upon collaborative approaches for performing science. These include concepts such as big teams approaches for conducting experimental research, developing data repositories centred on a holistic inter-disciplinary view of the athlete and exploring privacy preserving meta-analytic inspired concepts such as federated analyses or pooled synthetic data. These approaches have enormous potential but do come with their own difficulties and …

Two Strategies To Improve Stability In A Precision-Based Task: Insights From The Badminton Short Serve, Yochi Iino, Jodie Cochrane Wilkie, Senshi Fukashiro, Shinsuke Yoshioka, Shayne Vial
Research outputs 2022 to 2026
The badminton short serve is a highly precise task requiring accurate control of racquet face orientation, which directly influences shuttlecock trajectory and limits an opponent's ability to attack. Previous studies on motor redundancy have emphasized covariation among elemental variables as the primary mechanism for stabilizing performance. However, when the sensitivities of elemental variables differ, performance can also be stabilized by unevenly distributing individual variances without altering correlation — an approach that has received limited attention. This study investigated whether elite players use both the correlation strategy and the uneven variance strategy to stabilize racquet face angles during the short serve. …

Effects Of The Menstrual Cycle Phase On Rpe, And Symptom Characteristics In Pre-Professional Female Soccer Players, Emily Potts
College of Graduate Studies: Theses & Dissertations
Hormonal fluctuations across the distinct phases of the menstrual cycle have been shown to influence physiological and psychological responses to exercise, with some evidence suggesting phase-dependent changes in symptom presentation and ratings of perceived exertion (RPE); however, findings remain inconsistent, and few studies have examined these relationships across an entire competitive season in female soccer players. The purpose of this study was to examine changes in RPE and menstrual symptoms across cycle phases, as well as the relationships between RPE and symptom reporting in pre-professional female soccer players. A total of 22 female soccer players (age 22± 1.85) were recruited …

Test-Retest Reliability And Validity Of The Gas Exchange Threshold, Erik Ryan Snell Mr.
Theses and Dissertations--Kinesiology and Health Promotion
Theoretically, the gas exchange threshold (GET) demarcates the moderate and heavy intensity domains, whereby exercise performed at and below the GET results in a change in oxygen consumption ([ΔVO2] ≤ 200 mL), and exercise above the GET results in a slow component (ΔVO2 > 200 mL). This study examined the reliability and validity of the GET. 14 subjects performed two maximal graded exercise tests (GXTs) to determine the GET and its reliability. The minimal difference (MD = 21W) was applied to determine the GET above (GET+MD) and below (GET-MD) power outputs for 30 min …

Background/Objectives: Accurate assessment of neuromuscular reflexes, such as the Hoffmann reflex (H-reflex), plays a critical role in sports science, rehabilitation, and clinical neurology. Conventional interpretation of H-reflex electromyography (EMG) waveforms is subject to inter-rater variability and interpretive bias, limiting reliability and standardization. This study aims to develop an automated, interpretable, and robust agentic AI–driven framework for H-reflex waveform analysis. Methods: We propose a fine-tuned Vision–Language Model (VLM) consortium combined with a reasoning Large Language Model (LLM)–enabled decision support system for automated H-reflex interpretation. Multiple VLMs were fine-tuned on curated datasets of H-reflex EMG waveform images annotated with expert clinical observations, …

In many professional sport leagues, the worst-performing teams receive higher probability of earning top draft picks. This provides teams incentives to purposefully lose, or "tank," if they are not likely to contend for the playoffs or championships. We evaluate the effectiveness of tanking to improve team outcomes by examining the most explicit tanking case in the NBA: the "Trust the Process" Philadelphia 76ers. Using synthetic control, we demonstrate that tanking caused the 76ers to be more successful in terms of winning and operating income. However, only operating income had a plausibly positive present value when calculating discounted present values.

Sport is an essential part of a student-athlete’s life. Many student-athletes gain a strong “athletic identity” in their sport. When a student-athlete is faced with an injury, specifically a season-ending injury, they are at risk of facing a significant sense of loss of identity and adverse psychological effects on their mental health. In the collegiate athletic setting, athletic trainers are often the first to notice signs of psychological distress of student-athletes; however, they frequently report limited education, training, and confidence in providing necessary psychosocial interventions. The purpose of this capstone project was to increase occupational therapy’s visibility in the collegiate …

The purpose of this study is to explore how heart rate differs between scrimmages and competitions in varsity esports athletes at The University of Akron. This study also examines how heart rate varies across video game titles, as well as before and after both scrimmage and competition play. A scrimmage is defined as a practice game between two collegiate esports teams in which league standings and tournament eligibility are not affected by the outcome. In contrast, a competition is an official match between collegiate esports teams in which results directly influence league standings and tournament qualification.

Acute Changes In Muscle Thickness And Perceptual Responses Following Different Applications Of Blood Flow Restriction, Anuj J. Prajapati
Acute Changes In Muscle Thickness And Perceptual Responses Following Different Applications Of Blood Flow Restriction, Anuj J. Prajapati
Honors Undergraduate Theses
The use of blood flow restriction (BFR) allows for reductions in exercise intensity without compromising muscular adaptations that are typically only manifested during high-load non-BFR exercise. There exist, however, several ways to implement BFR and there is a lack of information regarding which application may be beneficial over another. The purpose of this investigation was to examine acute changes in muscle size and perceptual responses following different pressure applications of BFR (i.e., continuous BFR [cBFR], intermittent during sets BFR [iBFRsets], and intermittent during rest BFR [iBFRrest]) relative to an unrestricted condition (i.e., nBFR). Participants completed cBFR, …
