Learning to Cycle : A Cross-Cultural and Cross-Generational Comparison
2022
BackgroundLearning to cycle is an important milestone for children, but the popularity of cycling and the environmental factors that promote the development and practice of this foundational movement skill vary among cultures and across time. This present study aimed to investigate if country of residence and the generation in which a person was born influence the age at which people learn to cycle.MethodsData were collected through an online survey between November 2019 and December 2020. For this study, a total of 9,589 responses were obtained for adults (self-report) and children (parental report) living in 10 countries (Portugal, Italy, Brazil, Finland, Spain, Belgium, United Kingdom, M…
Hapenkulutuksen ja reiden lihasaktiivisuuden välinen yhteys pyöräilyssä
2002
Pollari, Terhi. Hapenkulutuksen ja reiden lihasaktiivisuuden välinen yhteys pyöräilyssä. LFY.203 Johdatus omatoimiseen tutkimustyöhön —kurssin tutkielma. Liikuntabiologian laitos. Jyväskylän yliopisto. Hapenkulutuksen kasvun tietyssä harjoituksessa on monesti oletettu olevan yhteydessä lisääntyneeseen lihasaktiivisuuteen työskentelevissä lihaksissa. Vaikka täysin selvää näyttöä ei ole, uskotaan hapenkulutuksen kasvun johtuvan lisääntyneestä motoristen yksiköiden käyttöönotosta tai syttymistiheydestä tehokkaan harjoituksen aikana. Hapenkulutusta ja lihasaktiivisuutta on tutkittu polkupyöräilyssä kuormilla, jotka ovat laktaattikynnystason kummallakin puolella. Tiettävästi pyöräilyssä ei kuite…
Beneficial Intervertebral Disc and Muscle Adaptations in High-Volume Road Cyclists.
2018
Purpose Cycling is widely practiced as a mode of transportation, a leisurely pursuit, and a competitive sport. Approximately half of cyclists experience low back pain. Yet, there has been limited study of spine tissue adaptations due to cycling.Methods To investigate potential risk factors for spinal pain, we compared 18 high-volume cyclists (>150 kmwk(-1) for 5 yr) to 18 height-matched nonsporting referents. Participants had no history of spinal pathology. Magnetic resonance imaging was used to quantify intervertebral disc (IVD) morphology and hydration, and psoas, erector spinae, quadratus lumborum, and multifidus muscle size and fat content. Endurance of trunk muscles (flexors and extens…
Cycling but not walking to work or study is associated with physical fitness, body composition and clustered cardiometabolic risk in young men
2020
IntroductionActive commuting is an inexpensive and accessible form of physical activity and may be beneficial to health. The aim of this study was to investigate the association of active commuting and its subcomponents, cycling and walking, with cardiometabolic risk factors, physical fitness and body composition in young men.MethodsParticipants were 776 Finnish young (26±7 years), healthy adult men. Active commuting was measured with self-report. Waist circumference was measured and body mass index (BMI) calculated. Aerobic fitness was measured with bicycle ergometer and muscular fitness with maximal leg and bench press, sit-ups, push-ups and standing long jump. Cardiometabolic risk factor…
Associations of active commuting to school in childhood and physical activity in adulthood
2023
AbstractThis study examined whether active commuting to school in childhood and adolescence predicted active commuting to work and overall physical activity (PA) in adulthood. Participants from the Young Finns Study (N = 2436) were aged 9–18 years in 1980 and followed up until 2018/2020. Their commuting modes to school were assessed with a self-reported questionnaire in 1980. Adulthood PA was assessed through self-reports regarding commuting modes to work (2001–2018), leisure-time physical activity (LTPA) (2001–2018), and objectively measured daily steps (2007–2018/2020). Associations between childhood commuting and adulthood PA were evaluated using regression analyses and multilevel models…
Effect of concurrent resistance and sprint training on body composition and cardiometabolic health indicators in masters cyclists
2016
In older previously sedentary individuals endurance training imposes a more effective stimulus to enhance cardiometabolic health compared with resistance or sprint training. We examined the effect of replacing a portion of endurance training with combined resistance and/or sprint training and how this influences cardiometabolic health indicators in masters endurance cyclists. Twenty-seven well-trained male road cyclists (53.7± 8.2 years) were allocated to a resistance and track sprintcycling training group (RTC, n= 10), an endurance and track sprint-cycling group (ETC, n = 7) or a control endurance group (CTRL, n = 10). Both the RTC and ETC groups completed a 12-week intervention of specifi…
Unravelling the rationalities of childhood cycling promotion
2022
Decrease of children’s independent mobility (CIM) has worried academics, policymakers, educators and other professionals for decades. Research and policy often emphasise that promoting children’s physically active and independent transport modes as cycling is important to achieve better public health, solve environmental challenges and increase related economic benefits. Yet, cycling promotion is not a neutral process and all promotion efforts are derived from latent notions of ‘cyclists’ and ‘cycling’. This paper discusses different rationalities of childhood cycling promotion and the representations of ‘children’ as independent ‘cyclists’ they entail. We argue that in order to efficiently…
From intensive car-parenting to enabling childhood velonomy? Explaining parents’ representations of children’s leisure mobilities
2023
Intensive parenting has become a key term for analysing the pressures and priorities of contemporary western parenting culture. For mobility studies it provides a discursive framework for understanding why children’s leisure has shifted from free play and mobility towards various adult-led organised activities and why parents deem it necessary to control children’s leisure journeys in an unprecedented manner. Most of the research on parenting and mobility has explained these trends with urban risks and safeguarding, but this paper highlights how parents also control, manage and enable children’s mobility to resource and enrich them with various dispositions. We use children’s mobility exper…
Towards sustainable mobility : Transformative scenarios for 2034
2022
Highlights • Increasing the share of walking and cycling is one of the building blocks of sustainable mobility transformation. • We organised an online Delphi survey for 30 walking and cycling experts during the first wave of COVID-19 pandemic. • Disaggregative Delphi analysis is elaborated based on the systemic restructuring of qualitative data. • Transport experts’ views of the future are described in the form of five walking and cycling scenarios up to 2034. • The results can be used for strategic transport planning and policy, and for identifying instruments for walking and cycling promotion in urban areas. Increasing the share of walking and cycling is one of the building blocks of sus…
Co-riding With My eBike to Get Green Lights
2019
Researchers are increasingly exploring interactive technology supporting human-system partnership in an exertion context, such as cycling. So far, most investigations have supported the rider cognitively, by the system "sensing and presenting" information to assist the rider to make informed decisions. In contrast, we propose systems that promote user-system co-operation, by "sensing and acting" on information to assist the rider, not only "cognitively" but also "physically", with the aim of facilitating user-system co-operation in an exertion context. Our prototype, "Ari", is a novel augmented eBike designed to facilitate user-system co-operation, where the information that each party can …
