Increased Healthspan From Exercise, Nicholas Boros

Scholar Week 2016 - present

In this talk we discuss important factors for increased healthspan. Much of the discussion will focus on strength training and cardiovascular training. In particular we outline optimal ways to increase strength and VO₂ max, which are the largest contributors to increased healthspan. We will also explain what makes a strength training program “optimal” mathematically.

Common Questions And Misconceptions About Protein Supplementation: What Does The Scientific Evidence Really Show?, Jose Antonio, Cassandra Evans, Arny A. Ferrando, Jeffrey R. Stout, Brandi Antonio, Harry P. Cintineo, Patrick Harty, Shwn M. Arent, Darren G. Candow, Scott C. Forbes, Chad M. Kerksick, Flavia Pereira, Drew Gonzalez, Richard B. Kreider

Faculty Scholarship

Protein supplementation often refers to increasing the intake of this particular macronutrient through dietary supplements in the form of powders, ready-to-drink shakes, and bars. The primary purpose of protein supplementation is to augment dietary protein intake, aiding individuals in meeting their protein requirements, especially when it may be challenging to do so through regular food (i.e. chicken, beef, fish, pork, etc.) sources alone. A large body of evidence shows that protein has an important role in exercising and sedentary individuals. A PubMed search of “protein and exercise performance” reveals thousands of publications. Despite the considerable volume of evidence, it is …

4-Week Neuromuscular Training Program On Peak External Power In The Back Squat In Division Ii Collegiate Athletes, Noah Smith

Honors Theses

Neuromuscular training has been shown to have many benefits to athletes ranging from increases in performance to decrease in injury risk by decreasing knee valgus in some athletes. The purpose of this study is to determine if neuromuscular training can influence power in athletes. It is hypothesized that with the intervention program there will be a significant increase in power in the sample. A 4-week neuromuscular training program was implemented with resistance trained athletes (Age: 20.13±.99 yrs., n=14). This training involved balance and plyometric exercises. A pretest and posttest consisted of 2 sets of 6 repetitions of a back squat …

The Effectiveness And Perceptions Of Three Moderate Intensity Walking Cadence Aids And Their Effects On Affective States: A Mixed Methods Study, Daniel Brown, Phillip Gray, Julie Doherty, Ellen Ea Simpson

International Journal of Exercise Science

International Journal of Exercise Science 17(5): 531-550, 2024. Substantial health benefits can be derived from walking at a moderate intensity cadence. To help regulate this cadence, three distinct aids exist 1) self-perception; 2) cadence prescription; 3) auditory cues. This study aimed to compare the effectiveness and explore perceptions of these aids to promote moderate intensity walking and effects on affective states, thereby addressing an important research gap. Individualised moderate relative intensity waking cadence was determined for participants (n = 23, M_age = 26.35, SD = 10.11). A convergent mixed-methods design was employed. A within-persons repeated measures design was used …

The Immediate Effects Of Dry Cupping The Lumbar Paraspinals On Range Of Motion And Temperature, Natasha Scavarelli, Paolo Sanzo

International Journal of Exercise Science

International Journal of Exercise Science 17(3): 551-564, 2024. Dry cupping is a therapeutic modality proposed to produce a negative pressure, stretching the skin and underlying tissue. This mechanism is said to promote regional blood flow of oxygenated blood and causing a physiological stretch in the tissue, allowing it to elongate and potentially changing skin temperature. The possible effects of the application to the lumbar spine paraspinal muscles, however, has not been thoroughly examined. The purpose of this pilot study was to explore the immediate effects of dry cupping the lumbar paraspinals on lumbar spine range of motion (ROM) and overlying …

Progressive Arm Cycling Ergometry With 3- And 5-Minute Stage Durations Yields Similar Estimates Of Substrate Oxidation In Healthy Adults, Todd A. Astorino Ph.D, Zachary Jordan, Cristian Gonzales, Carly Schuerger, Muhammed M. Atakan

International Journal of Exercise Science

International Journal of Exercise Science 17(2): 468-479, 2024. Arm cycling ergometry (ACE) leads to a lower maximal oxygen uptake (VO₂max) than cycling which is related to a smaller active muscle mass. This study compared estimates of fat and carbohydrate oxidation (FOx and CHOOx) between progressive exercise protocols varying in stage duration in an attempt to create a standard exercise protocol for determining substrate metabolism using ACE. Four men and seven women (age = 24 ± 9 yr) unfamiliar with ACE completed incremental exercise to determine peak power output and VO₂peak. During two subsequent sessions completed after …

Influence Of Physical Activity Including Squat Exposure On Trunk Muscle Strength And Labour Outcome In Pregnant Women, Rajal Savla, Rajani Mullerpatan, Bela Agarwal, Victoria Kuttan, Sushil Kumar

International Journal of Exercise Science

International Journal of Exercise Science 17(1): 504-516, 2024. Daily living physical activities of rural pregnant women, across most continents in the world, involve adoption of high-flexion postures like deep-squat. Deep-squat elicits substantial activation of major trunk and lower extremity muscles. Adequate strength of trunk muscles is known to facilitate forward-downward propulsion of baby during labour. Therefore, current study aimed to explore influence of overall physical activity including squat exposure on trunk and lower-extremity muscle strength and labour outcomes in rural and urban primigravida women. Twenty-eight primi-gravida women were stratified into 2 groups: rural habitual-squatters (n=14) and urban non-squatters (n=14). Daily …

The Quantification Of Muscle Activation During The Loaded Carry Movement Pattern, Samuel H. Ellestad, Thomas P. Holcomb, Alexis M. Swiergol, Michael E. Holmstrup Phd, Jeremy R. Dicus

International Journal of Exercise Science

International Journal of Exercise Science 17(1): 480-490, 2024. The ‘loaded carry’ is a popular resistance training activity that activates core musculature across multiple movement planes while the body is in locomotion. ‘Hold’ exercises are similar to carry exercises but lack the locomotive aspect. Both carry and hold exercises can be completed bilaterally (farmer’s carry (FC) and hold (FH)) or unilaterally (suitcase carry (SC) and hold (SH)). A deeper understanding of muscle activation between the FC and SC and intensity-matched FH and SH might improve their application. Healthy, college-aged individuals were recruited and surface electromyography of the rectus abdominis (RA), external …

The objective of this study was to systematically review the literature on the effect of CGs versus non-CGs (such as regular socks) or versus placebo garments on 1) the incidence of lower extremity sports injuries and 2) subjective ratings of fatigue and biomechanical variables in athletes at participating in any sport that required any level of running performance, given that fatigue-related biomechanical alterations may increase the risk of sports injuries. This study was a systematic review with meta-analyses. PubMed, Embase, CINAHL, Cochrane, PEDro, and Scopus were searched for eligible studies until 7 …

Reliability Of Popliteal Artery Flow-Mediated Dilation In The Seated Position, Taskina Akhter

Rehabilitation Sciences Theses & Dissertations

Flow-mediated dilation (FMD) is a noninvasive measurement of endothelial function, which is a useful prognostic tool for cardiovascular disease risk. Despite its widespread use since 1992, the reproducibility of FMD varies widely between studies. This variability in reproducibility is especially significant in the case of the popliteal artery due to different methodological approaches. Studies perform popliteal FMD in various body positions, with the prone and seated positions most common. However, no studies have examined the reproducibility of both the seated and prone positions of the popliteal artery FMD. Therefore, the aim of this study is to examine the test-retest and …

Cortisol Production In Female Soccer Players, Katelyn Seagraves

ASPIRE 2024

Cortisol is released from the adrenal glands when there is an apparent stressor. Exercise, while beneficial, is seen as stress to the body and incites increased cortisol release. Cortisol is known to increase with exercise, and higher-intensity exercise tends to raise cortisol more compared to lower intensities. However, less is known about interval training and cortisol concentrations.

This review of literature dives into the background of cortisol: how it's produced, what systems it regulates, and differences in production based on gender, stressors, exercise intensity, and duration. This paper identifies some knowledge gaps and links training intensities in soccer to cortisol …

‘You Have To Respect The Water’: Participant Experiences Of Appreciating And Managing The Risks Associated With Open Water Swimming – A Rapid Ethnographic Study, Mark A. Christie, David Elliott

International Journal of Aquatic Research and Education

Open water swimming (OWS) has rapidly grown in popularity, driven by the purported health benefits of cold-water immersion. A paucity of research remains specifically considering the notable risks inherent in OWS participation, and a lack of qualitative research on freshwater swimming experiences, and safety-related issues therein. This rapid ethnographic study, based at a dedicated OWS lake in the UK, conducted semi-structured interviews with OWS participants (n=17; female=11, male=6). Two core themes emerged: environmental issues impacting OWS experiences and behaviours; and knowledge and education of OWS which highlighted safe/unsafe practices, levels of education for managing risks, personal preparedness, swimming solo/with others, …

International Journal of Aquatic Research and Education

Drowning is a leading cause of fatality among children in the United States, and residential pools/spas currently account for as much as 80% of these submersion incidents. This study reviewed narrative case reports obtained from the United States Consumer Product Safety Commission (CPSC) to understand barrier location, type, and functionality as methods of pool/spa access for childhood submersion incidents. Retroactive analysis of 1,523 fatal and non-fatal submersion incidents among children aged 13 years old and younger was conducted using the CPSC in depth investigation dataset from 2000-2017. Narrative descriptions were coded according to the attributes of barrier location, functionality, and …

Lay Rescuer Equipment Preferences And Efficacy During A Simulated Drowning Event, Alison M. Miller, William D. Ramos, Kristina R. Anderson, Jill Cuvala

International Journal of Aquatic Research and Education

During a drowning incident where a lifeguard is not present, a bystander – referred to as a lay rescuer - may put themselves in danger by attempting a rescue. When lay rescuers can avoid entering the water by using rescue equipment to help a drowning victim, it serves to not only help the person actively drowning, but also provides a layer of protection to a lay rescuer. This study sought to examine the following questions: (a) which pieces of rescue equipment were preferred by lay rescuers at pre-determined short and long distances, (b) do lay rescuers select appropriate rescue equipment …

A Research Framework To Improve Evidence-Based Practice Surrounding The Resuscitation Response To Drowning In Surf Lifesaving, Elissa Hooper, Aaron T. Scanlan, Shayne D. Baker, Samantha Fien

International Journal of Aquatic Research and Education

Surf lifesaving members are essential first responders who patrol public waterways, performing rescues and resuscitation to individuals in the community when needed. In this way, surf lifesaving members experience arduous physical requirements alongside extensive psychological stress during resuscitation. Surf Life Saving Queensland (SLSQ) represents the predominant, frontline lifesaving service in Queensland, Australia; however, little research has explored key aspects of drowning resuscitations involving this organisation, as well as in the broader lifesaving industry, limiting our current understanding on this vital topic. We sought to explore key aspects of drowning resuscitations within SLSQ and create a framework to generate evidence-based practice. …
