Effects Of Inertial Measurement Unit Location On The Validity Of Vertical Acceleration Time-Series Data And Jump Height In Countermovement Jumping, Dianne Althouse, Cassidy Weeks, Steven B. Spencer, Joonsun Park, Brennan J. Thompson, Talin Louder

Kinesiology and Health Science Student Research

Inertial measurement units (IMUs) are an example of practical technology for measuring countermovement jump (CMJ) performance, but there is a need to enhance their validity. One potential strategy to achieve this is advancing the literature on IMU placement. Many studies opt to position a single IMU on anatomical landmarks rather than determining placement based on anthropometric principles, despite the knowledge that linear mechanics act through the segmental centers of mass of the human body. The purpose of this study was to evaluate the impact of positioning IMU sensors to approximate the trunk and lower-extremity segmental centers of mass on the …

Overview Of Mechanisms Related To Citrulline Malate Supplementation And Different Methods Of High-Intensity Interval Training On Sports Performance: A Narrative Review, Hadi Nobari, Laya Samadian, Saber Saedmocheshi, Pablo Prieto-González, Christopher Macdonald

Kinesiology

Regular exercise is a practical non-pharmacological approach to maintaining physical and mental health through rehabilitation and prevention of chronic diseases due to its cardiovascular, cardiorespiratory, neurological, and neuromuscular benefits. Despite awareness of the benefits of exercise, a “lack of time” has proven to be the most common impediment to regular activity. Thus, a time-efficient and potentially enjoyable training modality with growing popularity is high-intensity interval training (HIIT). HIIT incorporates intermittent bouts of work and recovery intervals performed at an intensity close to maximal oxygen consumption (VO2max). HIIT is considered to have equivalent or superior benefits compared to moderate-intensity continuous training …

We measured the BASAL breathing frequency following an overnight fast in adult,non-pregnant/non-lactating, inactive mammals ranging in body mass from 15 to5520 kg. The data included results from 338 individual animals from 34 speciesthat were divided into terrestrial, semi-aquatic (Otariidae and Phocidae) and aquaticmammals. Following attempts to limit the collection of breathing frequency usinga basal definition and to correct the analysis phylogenetically, our results suggestthat there are differences in the allometric mass-exponent between terrestrial andaquatic/semi-aquatic mammals. An allometric regression model, whereby both bodymass and breathing frequency were transformed using log10 , suggested that theallometric mass exponent for terrestrial mammals (−0.303) was …
