Besides these benefits, physical activity has also been linked to better academic achievement in certain studies. This study examines the relationship between physical activity and academic performance (national-based examinations) among adolescents in Malaysia. It was also designed to identify a feasible standardised physical activity programme. Methods: This is a multimethod study. The first phase is a prospective closed cohort study using data from 579 students from the Malaysian Health …

Effects Of Aging On Post-Exercise Oxygen Consumption: A Preliminary Study, Steven Klepacz

Health, Exercise, and Sports Sciences ETDs

Aging and excess post-exercise oxygen consumption (EPOC) is something that has not been adequately studied. Studies looking at EPOC mostly are compiled of young college age individuals. Aging in humans is a topic of much research with still more to be learned. The study in this paper attempts to answer the question of whether age affects EPOC when performing a certain exercise. Preliminary findings based on general age-related research suggest the possibility. This thesis will explore the current research related to age and EPOC, analyze the findings, and discuss additional avenues for future research.

Meeting, Moving, Mastering - A Text Analysis Of The Aesthetic Attractions Of 'Wild Swimming', Dagmar Dahl, Åsa I. Bäckström

International Journal of Aquatic Research and Education

Why are people fascinated by swimming in nature? This article addresses the aesthetic experiences of wild swimming as expressed by five wild swimming authors in their books. Drawing from aesthetic philosophy, we analyze the ways in which the appeal of wild swimming is described on three levels: the allure of water in the environment, the sensory encounter between water and the body, and the experience of moving in water. Furthermore, with reference to Seel’s concept of nature aesthetics (1996), the experience of wild swimming is analyzed in terms of contemplation, correspondence, and imagination. We can conclude that the special intensity …

Which Stroke Next? All Strokes Next! Part Two: Strokes For Intermediate And Advanced Swimmers, Robert Keig Stallman, Ebbe L. Horneman, Nils O. Vikander, Alexander Mwaipasi, Bente W. H. Laakso, Haakon - Paavo L. Nysted, Toni Ongala

International Journal of Aquatic Research and Education

The primary goal of this two-part project is to answer the rhetorical question of which strokes should be taught first, and which later (Langendorfer, 2013, Stallman, 2014a). As you have seen in Part One, we emphasize (as have many others) the need for a firm foundation before any stroke is introduced. When the learner is ready for propulsive motor competencies, there is no stroke which suits all as their first. In Part One we explored the “beginning strokes” all of which are candidates for any given learner’s first stroke. We also argued that after mastering their very first stroke the …

Towards A Globalised Vision Of Aquatic Competence, Rita F. Pinto, Juan Antonio Moreno Murcia

International Journal of Aquatic Research and Education

Human interaction with the aquatic environment has always taken different forms to meet the needs of pleasure, survival, therapy or performance. The diversity of existing aquatic spaces presents itself as a challenge, due to their variety, dynamism, unpredictability and unrepeatable conditions. These factors potentiate an infinite number of possibilities for human response in interaction with the aquatic environment, with aquatic competence being the one that will be able to sustain all types of interaction. Thus, the aim of the proposal has been to present a new approach to the contextualisation of aquatic competence. After a literature review on the concept …

Revisiting The Metaphorical Concept Of “No Strokes First - All Strokes First”: Part One - Beginning Strokes, Robert Keig Stallman Ph.D., Alex Mwaipasi, Ebbe Laakso Horneman, Nils Olof Vikander, Bente Wäinösdatter Horneman Laakso, Haakon-Paavo Laakso Nysted, Toni Ongala

International Journal of Aquatic Research and Education

The aim of this article is to address the familiar question “Which swimming stroke should be taught first?” The discussion is usually focused on breaststroke versus crawl. Provoked by these naïve discussions of which stroke should be taught first (as if stroking equals swimming, which it emphatically does NOT), the question was answered metaphorically in an earlier article “No Stroke First – All Strokes First” (Stallman, 2008a). Here in Part I we identify and describe six strokes, all of which might be a candidate for any learners ‘very first’ stroke. We describe them as beginning strokes. Having identified and learned …

The Western Ontario & McMaster Universities Osteoarthritis Index (WOMAC), numerical rating scale (NRS), timed up-and-go (TUG), and 10-m walk were assessed in 6 adults (62.7 ±14.2 years) who participated in an 8-week (3x/wk) UT walking intervention based on the Arthritis Foundation’s Walk With Ease (WWE) program. Walking pace was self-selected, and walking duration of each session was increased from 10 to 45 minutes throughout the study. Knee pain and function were …

An Exploratory Study Of The Effects Of Aquatic Walking On Function And Muscle Activity In Knee Osteoarthritis: Part 2, John M. Coons, Brandon Grubbs, Conor Theiss, Vaughn W. Barry, Sandra Stevens

International Journal of Aquatic Research and Education

This paper presents Part 2 of a study that investigated the effects of an 8-week (3x/week) underwater treadmill (UT) walking intervention on knee osteoarthritis (KOA) outcomes in 6 adults with KOA (62.7 ± 14.2 years). The Knee Outcome Survey (KOS) for activities of daily living and muscle activity during a 10-m walk and a 20 cm step down were measured before and after the intervention. The following KOS measures improved after the UT walking program (p < 0.05; g > 0.8): stiffness, swelling, weakness, walking, going up stairs, going downstairs, kneeling on the front of the knee, squatting, and sitting with the …

The Real-Time Classification Of Competency Swimming Activity Through Machine Learning, Larry Powell, Seth Polsley, Drew Casey, Tracy Hammond

International Journal of Aquatic Research and Education

Every year, an average of 3,536 people die from drowning in America. The significant factors that cause unintentional drowning are people’s lack of water safety awareness and swimming proficiency. Current industry and research trends regarding swimming activity recognition and commercial motion sensors focus more on lap swimming utilized by expert swimmers and do not account for freeform activities. Enhancing swimming education through wearable technology can aid people in learning efficient and effective swimming techniques and water safety. We developed a novel wearable system capable of storing and processing sensor data to categorize competitive and survival swimming activities on a mobile …

Sit Less, Move More: A National Study Of Physical-Activity Behavior And Cancer, Stella O. Nwogugu

Dissertations, Theses, and Capstone Projects

Background: Physical activity is associated with lower risks of cancer, the second leading cause of death among Americans. Yet, sedentary behavior is the prevailing lifestyle for about 80% of American adults. Additionally, cancer survivors remain significantly inactive, even though physical activity has been shown to decrease risk of cancer and cancer recurrence, improve tolerance of cancer therapy, and reduce mortality. This research explores the relative impact of personal agency, social support, and key demographic variables on physical-activity behavior for a national sample of adults as well as how these relationships differ for cancer survivors and their counterparts.

Methods: Using the …

Enhancing The Quality Of Life For Senior Citizens: A Facilitator’S Guidebook For Mindful Music And Movement, Shannon Sexton

Mindfulness Studies Theses

Music appreciation and enjoyment enhance well-being throughout the lifespan. The challenges and constraints that people experience as they age can lead to lack of access to music, decreased physical activity, and fewer avenues for creative expression. Group music and movement interventions created for older populations offer opportunities for social connection and improved quality of life. Mindful practices add further benefit when combined with these interventions. Current available programs are scarce and most often do not encompass mixed modalities. In addition, the benefits of these programs do not show long-term sustainability. The purpose of this thesis is to explore the effects …

In this regard, the purpose of this systematic review was to identify factors associated with lifeguards’ performance. After extensive research on PsycArticles, PsicBooks, PsycInfo, SportDiscus, Web of Science, PubMed, Scopus and SportDiscus databases, containing the keywords “lifeguard” AND “performance”, “lifeguard” AND “skills” and “lifeguard” AND “drowning”, we obtained 429 research articles. After eliminating duplicates, excluding those that had no relevance to the study, and screening against set criteria, a total of five articles were fully reviewed. …

Effects Of A Demand-Valve Scuba Regulator On Cardiorespiratory Response During Submaximal Exercise Under Normobaric Conditions: A Preliminary Investigation, Christopher R. Kovacs Ph.D., Camille Dhom B.S.

International Journal of Aquatic Research and Education

SCUBA diving fatalities are often related to cardiac events triggered by stress linked to equipment. The purpose of this investigation was to examine the effects of a SCUBA regulator on cardiorespiratory exercise at a submaximal workload. Ten participants (mean = 21.5 yrs; s.d. = 1.16) completed two submaximal exercise tests at 1 ATA; one while breathing normally and a second while breathing directly from a demand valve SCUBA regulator. Total time to test completion (TOT), heart rate (HR), blood pressure (BP), rating of perceived exertion (RPE), and arterial oxygen levels were all assessed. No significant differences between conditions were found …

Effect Of Water Depth On Heart Rate And Core Temperature During Underwater Treadmill Walking, Carrie E. Bajenski, Brianna R. Brandon, Cailey A. Curry, Leslie Fajardo, Ryan T. Conners

International Journal of Aquatic Research and Education

Exercising using an underwater treadmill (UTM) has become a popular modality; however, few studies have focused on the physiological demands of UTM walking at varying water depths. Thus, the objective of this study was to investigate changes in heart rate (HR) and core temperature (CT) values in college-aged males and females while exercising at different water immersion depths using an UTM. Twenty participants (age = 21.50 ± 2.19 years; height = 169.04 ± 10.85cm; weight = 75.56 ± 22.28kg) walked at water depths of 10cm below the xiphoid process and at the level of the superior iliac crest (I.C.). Each …

Body Composition Assessment In Masters Level Swimmers, Megan E. Larson, Amy Morgan, Jessica Kiss, Mary-Jon Ludy

International Journal of Aquatic Research and Education

Body composition of collegiate swimmers has been extensively studied; however, there are limited reports of body composition among Masters swimmers. This study compared the accuracy of air displacement plethysmography (ADP) and bioelectrical impedance (BIA) to the gold standard method of underwater weighing (UWW) in Masters level swimmers. The relationship between percent body fat (%BF) and body mass index (BMI) was also assessed. Recruitment (n = 6 females, 11 males) occurred at two Masters swim clubs. Pearson correlation coefficients revealed no significant differences between ADP, BIA, and UWW (p > 0.05). For both female and male Masters swimmers, the mean %BF …

Do Water Safety Lessons Improve Water Safety Knowledge?, Michael J. Tipton, Joseph Muller, Cristian Abelairas Gomez, Jo Corbett

International Journal of Aquatic Research and Education

A person, usually a child or young adult, dies by drowning every 90 seconds around the planet. Most drowning prevention initiatives do not assess the efficacy of the intervention. In this study, thirteen- to fourteen-year-olds had their level of water safety knowledge (covering cold shock, rips and tides) assessed before, just after, and 3-6 months after one, 25-minute water safety lesson on these topics. We evaluated the knowledge gained and retained on water safety “awareness” (i.e., knowledge of risks) and “confidence” in terms of knowing what to do in an emergency. The results demonstrated that the lesson significantly increased water …

International Journal of Aquatic Research and Education

Improved eating behaviors and daily participation in physical activity such as swimming might abate the likelihood of African American youth becoming obese. Yet many African American youth neither consume the recommended daily servings of nutritious foods nor know how to swim. The purpose of this study was to investigate the impact of a culturally tailored multicomponent summer intervention to reduce obesity and unintentional drownings among underserved African American youth. Children (n = 145) participated in a three-hour, community-based intervention for four weeks. Measures of children’s attitudes perceived behavioral control, and subjective norms toward swimming, nutrition, and physical fitness were …

Getting In: Safe Water Entry Competencies, Kevin Moran Dr, Jennifer Blitvich, Lauren Petrass, Keith Mcelroy

International Journal of Aquatic Research and Education

In high income countries, jumping and diving into water are a small but persistent cause of death and serious injury especially among male youth and young adults. Although water entries maintain a high media profile, little is known about what entry competencies and underlying water safety knowledge youth bring to this practice. Undergraduates enrolled in aquatics (N= 76) completed a survey before attempting 7 entry jumping and diving tasks. While safety attitudes and self-reported behaviours were generally good, considerable variation in practical entry competence was evident. Most completed a deep-water compact jump (87%) and PFD jump (88%) with …

Perceptions Of Water Competencies, Drowning Risk And Aquatic Participation Among Older Adults, Teresa Stanley, Kevin Moran

International Journal of Aquatic Research and Education

New Zealand has an aging population and, despite falling drowning tolls in all other age groups (WSNZ, 2019c), older adults have continued to drown in both increasing numbers and proportion. The reasons for this are not well understood since very little drowning research has focused on older people. A water safety survey (N = 389) seeking information on older adults’ aquatic recreational practices and perceptions of safety was conducted at the end of the summer season, 2019. Most adults (86%, n = 335) reported some aquatic activity in the previous year, but those aged 65+ years (66%) were significantly …

Water Safety Education Programs In Culturally And Linguistically Diverse Seattle Communities: Program Design And Pilot Evaluation, William A. Koon, Elizabeth Bennett, Sarah Stempski, Jennifer Blitvich

International Journal of Aquatic Research and Education

Drowning is a public health concern that disproportionally affects children and minorities in Washington State. Community health educators from Seattle Children’s Hospital designed a Water Safety Education and Lifejacket Giveaway Program for low-income parents of preschool-aged children from culturally and linguistically diverse backgrounds. The program was interpreted into multiple languages and parents and children in attendance received free lifejackets. The mixed-methods pilot evaluation of this program found statistically significant relationships between language and self-reported parent swim skill level (English-speaker OR 4.6; 95%CI: 1.84 – 11.54); and confidence of keeping one’s child safe (English-speaker OR 3.34; 95%CI: 1.10 – 10.4). Additionally, …

Surfboard Paddling Technique And Neuromechanical Control: A Narrative Review, Wynand Volschenk, Zachary J. Crowley-Mchattan, John W. Whitting, Rudi A. Meir, Alec K. Mckenzie

International Journal of Aquatic Research and Education

Surfboard paddling is an essential activity when surfing. Research investigating surfboard paddling, especially as it pertains to neuromechanical control and techniques used, is limited. Previous research made use of swim ergometers to examine surfboard paddling demands. The validity of using swim ergometers in surfboard paddling research and training deserves further analysis. To establish ecologically valid findings, researchers have begun to use swim flumes and still-water paddling environments to investigate paddling efficiency and technique. This emerging body of research has reported that muscle activation patterns, intensities, and timings differ as surfers move through different paddle stroke phases. A deeper understanding of …
