Cardiorespiratory fitness is not associated with risk of venous thromboembolism: a cohort study
2019
Objectives. The inverse and independent association between cardiorespiratory fitness (CRF) and arterial thrombotic disease is well established. However, the potential association between CRF and venous thromboembolism (VTE) is not well known. We aimed to assess the prospective association of CRF with the risk of VTE. Design. Cardiorespiratory fitness, as measured by maximal oxygen uptake (VO2max), was assessed using a respiratory gas exchange analyser in 2,249 men aged 42-61 years without a history of VTE at baseline in the Kuopio Ischemic Heart Disease prospective cohort. Cox-regression models were used to calculate hazard ratios (HR) with 95% confidence interval (CI) for VTE. We correcte…
Optimal Physical Training During Military Basic Training Period
2015
The goal for military basic training (BT) is to create a foundation for physical fitness and military skills of soldiers. Thereafter, more advanced military training can safely take place. Large differences in the initial physical performance of conscripts or recruits have led military units to develop more safe and effective training programs. The purpose of this review article was to describe the limiting factors of optimal physical training during the BT period. This review revealed that the high volume of low-intensity physical activity combined with endurance-type military training (like combat training, prolonged physical activity, and field shooting) during BT interferes with optimal…
Cardiopulmonary exercise testing in COVID-19 patients at 3 months follow-up☆
2021
Abstract Background Long-term effects of Coronavirus Disease of 2019 (COVID-19) are of utmost relevance. We aimed to determine: 1) the functional capacity of COVID-19 survivors by cardiopulmonary exercise testing (CPET); 2) the characteristics associated with cardiopulmonary exercise testing (CPET) performance; 3) the safety and tolerability of CPET. Methods We prospectively enrolled consecutive patients with laboratory-confirmed COVID-19 from Azienda Sanitaria Locale 3, Genoa. Three months after hospital discharge a complete clinical evaluation, trans-thoracic echocardiography, CPET, pulmonary function tests, and dominant leg extension (DLE) maximal strength measurement were performed. Res…
Effect of Sex, Body Mass Index and Physical Activity Level on Peak Oxygen Uptake Among 14–19 Years Old Adolescents
2020
The aim was to describe longitudinal trends in peak oxygen uptake (VO2peak) among 14- to 19-year-old adolescents in Norway, and to examine effects of sex, body mass index (BMI), and physical activity (PA) level on VO2peak during adolescence. Of 124 invited students from two lower secondary schools in Norway, 116 eighth-grade students (61 boys and 55 girls; 14 years old at baseline) volunteered to participate. The study has a longitudinal design with 6 yearly repeated measures of body height and mass, VO2peak and PA level. VO2peak allometrically scaled to body mass raised to the power of 0.67 was measured using a walking or running incremental test on a treadmill, whereas PA level was self-r…
Predicting the 2000‐m Rowing Ergometer Performance from Anthropometric, Maximal Oxygen Uptake and 60‐s Mean Power Variables in National Level Young R…
2020
Abstract Many studies reported various relationships between 2000-m rowing performance and anthropometric as well as metabolic variables, however, little is known about 60-s mean power in elite youth athletes. The aim of this study was to develop different regression models to predict 2000-m rowing indoor performance time (t2000) using anthropometric variables, maximal oxygen uptake (VO2max) and mean power established during a 60-s all-out test (W60) in national elite youth rowers. Fifteen youth male Italian rowers (age: 15.7 ± 2.0 years; body height: 176.0 ± 8.0 cm; body mass: 71.2 ± 10.0 kg) performed an incremental maximal test, a 60-s all-out test and a 2000-m race simulation using a Co…
Salibandymaalivahdin antropometria ja fyysinen suorituskyky
2017
Johdanto. Maalivahti on merkittävä pelipaikka salibandyssa, jossa maalivahdin tarkoituksena on estää vastustajan maalinteko 1.60 m x 1.15 m kokoisiin maaleihin. Tämän tutkimuksen tavoitteena oli profiloida salibandymaalivahdin antropometriaa ja fyysistä suorituskykyä ja niiden mahdollista yhteyttä maalivahdin torjuntatehokkuuteen sekä valottaa muuttujien eroja nais- ja miesmaalivahtien välillä. Menetelmät. Mittaukset toteutettiin marras-joulukuussa kaudella 2016 - 2017 aineiston koostuessa Suomen Salibandyliiton eri sarjoissa (naisten salibandyliiga, miesten II-divisioona, A-poikien SM-sarja) pelanneista maalivahdeista (n = 9). Koeasetelma sisälsi monipuolisesti antropometriaa ja fyysistä s…
Seasonal variations in endurance performance, and aerobic and anaerobic variables in competitive cross country skiers
2016
Cross country skiing is known as an endurance sport and both aerobic and anaerobic systems have a major impact on performance in cross country skiers. Coaches and athletes use periodized training programs to optimize physiological adaptations and increase performance. Knowing how the major aerobic and anaerobic variables change during the course of one ski season will allow better implementation of training programs. This study examined variations in endurance performance, and how that relates to the variation in different aerobic and anaerobic variables. There were 19 subjects in the study, 11 male and 8 female. All subjects were competitive cross country skiers. The study took place over …
Effects of Repeated Sprint Training in Hypoxia on Physical Performance Among Athletes : A Systematic Review
2021
Repeated sprint training in hypoxia (RSH) represents an innovative method in the process of development and improvement of physical performance among athletes. However, there is less scientific data on this topic. The purpose of this systematic review was to investigate the effect of RSH method on motor abilities and performance among athletes, obtain new information, and expand the already known conclusions. The data search was performed of 4 electronic databases for the years 2000-2021 May as follows: Google Scholar, PubMed, Web of Science, and ResearchGate. This search with English language restriction was made by using the following terms, individually/combination: "repeated sprint abil…
Nutritional intake and anthropometric characteristics are associated with endurance performance and markers of low energy availability in young femal…
2023
Background Low energy availability (LEA) can have negative performance consequences, but the relationships between LEA and performance are poorly understood especially in field conditions. In addition, little is known about the contribution of macronutrients to long-term performance. Therefore, the aim of this study was to evaluate if energy availability (EA) and macronutrient intake in a field-based situation were associated with laboratory-measured performance, anthropometric characteristics, blood markers, training volume, and/or questionnaire-assessed risk of LEA in young female cross-country (XC) skiers. In addition, the study aimed to clarify which factors explained performance. Metho…
Harjoittelun vaikutus palautumiseen maksimaalisesta hapenottokyvyn testistä ja palautumisen yhteys harjoitusvasteeseen
2012
Tutkimuksen tarkoituksena oli selvittää kuinka kuntotasoltaan erilaiset varusmiehet palautuvat maksimaalisesta hapenottokyvyn (VO2max) testistä, onko palautuminen yhteydessä harjoitusvasteeseen ja kuinka fyysisesti kuormittavaa peruskoulutuskausi varusmiehille on. Palautumisen, harjoitusvasteen ja harjoituskuorman yhteyksiä toisiin-sa mitattiin syke- ja hengityskaasumuuttujia käyttäen. Koehenkilöinä oli 59 varusmiestä (ikä19.6 ± 0.3 v). VO2max mitattiin viikoilla 1, 5, 8 ja 10 ja varusmiehet jaettiin kol-meen kuntoluokkaan viikolla yksi mitatun VO2max:n perusteella (>45 ml/kg/min aktii-vi; 40–44.9 ml/kg/min harraste ja <39.9 ml/kg/min perus). Harjoituskuorma TRIMP laskettiin sydämen sykkeen…
