Leisure‐time cross‐country skiing is associated with lower incidence of type 2 diabetes : A prospective cohort study

2020

Aims. Cross‐country skiing is associated with reduction in risk of adverse vascular outcomes, but its association with type 2 diabetes is uncertain. We aimed to assess the associations between leisure‐time cross‐country skiing habits and incident type 2 diabetes. Methods. We analyzed data of 2,483 middle‐aged men with no history of diabetes at baseline in the KIHD prospective study. The frequency, average duration, and intensity of leisure cross‐country skiing were assessed at baseline using a 12‐month physical activity questionnaire. Hazard ratios (HRs) (95% CIs) for type 2 diabetes were estimated. Results. During a median follow‐up of 21.6 years, 539 men developed type 2 diabetes. Type 2 …

Heat shock protein 70 and exercise: morphofunctional relationships

2008

The acute effects of different high-intensity conditioning activities on sprint performance differ between sprinters of different strength and power …

2021

The purpose of the present study was to examine the effect of different conditioning activities (CAs) on short-term increase in sprint performance. In twelve male sprinters (21.1+2.6 years, 100 m performance: 11.5+0.6 s) their body composition, half squat maximum strength, 100 m sprinting and countermovement jump performances were evaluated. The performance of a 50 m sprint (splits at 10 m, 30 m and 50 m) was evaluated before and 5, 10 and 15 min after four postactivation performance enhancement CAs on different occasions: [1] 3 sets x 4 s maximum isometric half squat (IHF), [2] 3 sets x 3 consecutive countermovement jumps (cCMJs), [3] 3 repetitions x 30 m overspeed sprinting (OVSP) and [4]…

Acute impact of exercise on pro-onflammatory molecule concentrations in blood : factors that affect exercise induce response

2013

Pētījuma mērķis bija izpētīt slodzes intensitātes un ilguma, kā arī fiziskās sagatavotības līmeņa un imobilizācijas ietekmi uz citokīnu un citu slodzes izraisītu signālvielu koncentrācijām asinīs. Kopumā 98 jauni, veseli un fiziski aktīvi vīrieši piedalījās 4 dažādos fiziskās slodzes testos. Asins paraugi citokīnu un citu signālvielu noteikšanai tika ņemti pirms, pēc, kā arī slodzes laikā. Rezultāti liecina, ka akūta fiziskā slodze izraisa iekaisuma molekulu koncentrācijas pieaugumu asinīs. Pieaugot slodzes ilgumam un intensitātei, šī organisma atbildes reakcija pastiprinās, savukārt augstāks fiziskās sagatavotības līmenis šo reakciju samazina. Atkarībā no fiziskās slodzes veida, intensitāt…

Career Adapt-Abilities Scale – Dual Career Form (CAAS-DC): psychometric properties and initial validation in high-school student-athletes

2016

Talented adolescent athletes attempting to sustain academic and vocational training alongside the increasing demands of their athletic career often encounter difficulties, including lower vocational readiness and the challenge of adapting to life after elite sport. Therefore, it is necessary to better understand the specific competencies that youth athletes can draw upon to successfully combine sport and education into a dual career pathway. Building on the existing Career Adapt-Abilities Scale [Savickas & Porfeli, (2012). Career adapt-abilities scale: Construction, reliability, and measurement equivalence across 13 countries. Journal of Vocational Behavior, 80(3), 661–673], we developed a …

Encuentro de saberes: Huellas de memoria pluriversa y descolonización de la Universidad contemporánea

2018

This paper studies the Encounter of Knowledge as a project that, by welcoming mestres and mestras of ancestral knowledge into universities, contributes to decolonize higher education, broadening its field of memory. Based on a systematization exercise, we established a theoretical dialogue with Bajtin and Bejamin. Based on the participation of four mestres -Lucely Pío, raicera del Cerrado, Mãe Lu and Tata Mutá Imé, religious leaders of Candomblé and the political leader and shaman Álvaro Tukano of the Tukano nation- we show how the project promotes in the contemporary Brazilian university a space of mnemic pluriversity, capable of activating diverse narrative planes (biographical, political…

Physical exercise increases adult hippocampal neurogenesis in male rats provided it is aerobic and sustained

2016

Aerobic exercise, such as running, has positive effects on brain structure and function, such as adult hippocampal neurogenesis (AHN) and learning. Whether high-intensity interval training (HIT), referring to alternating short bouts of very intense anaerobic exercise with recovery periods, or anaerobic resistance training (RT) has similar effects on AHN is unclear. In addition, individual genetic variation in the overall response to physical exercise is likely to play a part in the effects of exercise on AHN but is less well studied. Recently, we developed polygenic rat models that gain differentially for running capacity in response to aerobic treadmill training. Here, we subjected these l…

Acute and chronic effects of cold treatment on physiological variables and neuromuscular function during a short training period in men

2015

Introduction. Recovery following various physical exercises is a complicated process. The exercise session can involve strong demands on both muscle structure and energy production (aerobic and anaerobic). Many exercise sessions also induce muscle damage (exercise induced muscle damage; EIMD). Different recovery methods attempt to alleviate or prevent EIMD and its associated symptoms, such as muscle soreness and swelling, and reduction in muscle function. One of the used strategies is cold treatment (cryotherapy), which decreases tissue temperature and subsequently effects on e.g. blood flow, metabolism and neural conductance velocity. To date, there is conflicting evidence to support the u…

Rethinking validity in qualitative sport and exercise psychology research: a realist perspective

2019

Over the last two decades, the relativist approach has significantly shaped debates about the quality and rigour of qualitative research in sport and exercise psychology (SEP). In the absence of any published critiques of relativism in SEP, this paper problematises its central claims with a focus on the most recent contribution offered by Smith and McGannon (2018 Smith, B., & McGannon, K. R. (2018). Developing rigor in qualitative research: Problems and opportunities within sport and exercise psychology. International Review of Sport and Exercise Psychology, 11, 101–121. doi: 10.1080/1750984X.2017.1317357[Taylor & Francis Online], [Web of Science ®], , [Google Scholar]. Developing rigor in …
