Background: Stretching has wide appeal, but there seems to exist some mismatch between its purported applications and what the evidence shows. There is compelling evidence for some stretching applications, but for others, the evidence seems heterogeneous or unsupportive. The discrepancies even affect some systematic reviews, possibly due to heterogeneous eligibility criteria and search strategies. This consensus paper seeks to unify the divergent findings on stretching and its implications for both athletic performance and clinical practices by delivering evidence-based recommendations. Methods: A panel of 20 experts with a blend of practical experience and scholarly knowledge was assembled. The panel meticulously reviewed …

Corrected Echo Intensity Is Not Related To Fatigability Or Indices Of Aerobic Fitness In Healthy Young Adults: A Pilot Study, Kase J. Pennartz, Michael R. Perlet, Marek Kerr, Joshua L. Keller
International Journal of Exercise Science: Conference Proceedings
Muscle quality (MQ), measured via echo intensity, is regularly used to characterize muscle function and disease. Although it has been related to measures of cardiovascular performance, muscle strength, power, and function in elderly populations, these relations are not consistently observed in younger adult populations. Specifically, the relations of MQ and various functional outcomes (e.g., muscle strength, fatigability, and aerobic fitness) remain unclear, particularly given the interplay between age-related changes in fatiguability and performance. PURPOSE: Therefore, the purpose of this study was to examine the relation of MQ among muscle strength, fatigability, and indices of aerobic fitness in young healthy …

Exercise Science Faculty Research and Publications
Background
In people with multiple sclerosis (pwMS), muscle fatigue and weakness are common issues that can interfere with daily activities. Photobiomodulation therapy (PBMT), comprising light in a 600–1100 nm bandwidth, is a low-level laser therapy thought to improve muscle performance in non-disease populations, in part, by improving mitochondrial function and thus, might be beneficial in pwMS. Given this potential, we aimed to investigate the effects of PBMT on muscle performance in pwMS, both in the short-term and over an extended period.
Methods
This study consisted of two parts with a randomized double-blind crossover design. In study I, muscle function was …

Research outputs 2022 to 2026
There is substantial evidence indicating that increased maximum strength as a result of training with squats, particularly full and parallel squats, is associated with superior athletic capabilities, such as sprinting, jumping and agility. Although full and parallel squats have been strongly associated with sport performance, there is also some evidence that the use of partial squats may provide angle specific adaptations that are likely advantageous for specific sporting activities. Partial squats may be particularly advantageous when trained in conjunction with full or parallel squats, as this practice results in a greater training effect. There is a paucity of evidence that …

Effects Of Eccentric Nordic Hamstring Exercise On Fascicle Length In Females, Sarah J. Triemstra
All NMU Master's Theses
The eccentric Nordic hamstring exercise (NHE) may be useful for increasing fascicle length (FL) of the bicep femoris long head and reduce the risk of hamstring strain injury. Compared to changes in hamstring strength, FL has been shown to reduce the risk of injury to a greater extent. While previous studies have investigated the eccentric NHE on FL, many lack control groups, female participants, and have not measured performance outcomes. Our aim was to examine the effect of 6-weeks of NHE on FL and measures of performance in females. Seven recreationally active females (age: 22.43 ± 2.99 years; BMI: 20.8 …

Topics in Exercise Science and Kinesiology Volume 4: Issue 1, Article 4, 2023. Phase angle (PhA) has emerged as a prognostic indicator of survival and quality of life (QOL) in cancer patients. Identifying measures of physical fitness that correlate with PhA can provide guidance toward optimizing cancer rehabilitation programs and future research. The purpose was to examine the relationship between PhA and physical fitness in breast cancer survivors. Sixty-three breast cancer survivors (60 ± 9 years, PhA 4.59±0.52, mean±SD) completed assessments for muscular strength, muscular endurance, cardiorespiratory endurance, flexibility, and body composition. PhA and body composition were measured using bioimpedance …

International Journal of Exercise Science: Conference Proceedings
Handgrip peak force and rate of force development (RFD) measurements have been shown to be effective parameters at characterizing the strength capacities of numerous muscle groups, including those of the lower extremities. However, the reliability of these measurements and their relationship with vertical jump (VJ) peak power remains uncertain. PURPOSE: The purpose of this study was to examine the reliability of handgrip peak force and RFD measurements. A secondary aim was to determine if these measurements are correlated with the peak power produced during a VJ test. METHODS: Twenty young, healthy women (age = 21 ± 3 years) …

Graduate Theses, Dissertations, and Problem Reports (ETD)
The expanding opportunities to implement sport science frameworks in elite-level basketball environments coincide with the sport’s increasing global prominence. Concomitant to these opportunities is the continual growth of the sport technology market (e.g., wearables, force plates) and computational power (e.g., data management tools, coding capabilities), which yields solutions and challenges for both athletes and practitioners. Due to the rapid influx of new sport technologies in high performance environments, particularly American Collegiate Men’s Basketball, more formal and ecologically valid research on how to effectively utilize data derived from them, particularly over long periods of time (i.e., multiple seasons) is needed.
