Etäteknologiaa sisältävien liikunnallisten kuntoutusinterventioiden vaikuttavuus maksimaaliseen hapenottokykyyn : järjestelmällinen kirjallisuuskatsa…
2017
Hengitys- ja verenkiertoelimistön kunnon on todettu olevan yhteydessä useisiin sairauksiin ja eliniänodotteeseen. Etäteknologiaa sisältävillä interventioilla on todettu olevan yhteys fyysiseen aktiivisuuteen ja hengitys- ja verenkiertoelimistön kuntoon, mutta tutkittua vaikuttavuustietoa on vähän. Maksimaalinen hapenottokyky on yleisesti käytetty hengitys- ja verenkiertoelimistön kunnon mittari, ja se kuvaa hengitys- ja verenkiertoelimistön kykyä kuljettaa happea lihaksille. Tämän järjestelmällisen kirjallisuuskatsauksen tavoitteena oli selvittää etäteknologiaa sisältävien liikunnallisten kuntoutusinterventioiden vaikuttavuutta maksimaaliseen hapenottokykyyn. Kirjallisuushaku tehtiin (2000–…
Effects of initial performance, gross efficiency and VO_2peak characteristics on subsequent adaptations to endurance training in competitive cyclists
2018
The present study investigated the effects of initial levels of cycling performance, peak oxygen uptake (www.frontiersin.orgO2peak) and gross efficiency (GE) on the subsequent adaptations of these variables and their relationship following high-intensity training (HIT) designed to increase www.frontiersin.orgO2peak in competitive cyclists. Sixty cyclists (www.frontiersin.orgO2peak = 61 ± 6 mL kg-1 min-1) were assigned a 12-week training program consisting of twenty-four supervised high-intensity interval training sessions and ad libitum low intensity training. GE was calculated at 125, 175, and 225 W and performance was determined by mean power during a 40-min time-trial (Power40 min). In a…
Aerobic capacity and respiratory patterns are better in recreational basketball-engaged university students than age-matched untrained males
2021
Abstract Study aim: To asses and compare the aerobic capacity and respiratory parameters in recreational basketball-engaged university students with age-matched untrained young adults. Material and methods: A total of 30 subjects were selected to took part in the study based on recreational-basketball activity level and were assigned to a basketball (BG: n = 15, age 22.86 ± 1.35 yrs., body height 185.07 ± 5.95 cm, body weight 81.21 ± 6.15 kg) and untrained group (UG: n = 15, age 22.60 ± 1.50 yrs., body height 181.53 ± 6.11 cm, body weight 76.89 ± 7.30 kg). Inspiratory vital capacity (IVC), forced expiration volume (FEV1), FEV1/IVC ratio, maximal oxygen consumption (VO2max), ventilatory thre…
Influence of time-of-day-specific same-session combined endurance and strength training on maximal and submaximal endurance parameters
2015
Endurance and strength training are often performed concurrently by both elite athletes and recreational individuals. The question of whether the order of exercises or training at certain daytimes yields to different adaptations in endurance and strength parameters, when endurance and strength training are combined into a single training session, has received limited scientific attention. Moreover, effects on cardiorespiratory and neuromuscular variables after same-session concurrent training have shown conflicting results, particularly regarding exercise sequence or time-of-day characteristics. The purpose of the present study was to examine the effect of time-of-day-specific same- session…
Effects of resistance training frequency on cardiorespiratory fitness in older men and women during intervention and follow-up.
2017
This study investigated the effects of resistance training (RT) performed with different frequencies, including a follow-up period, on cardiorespiratory fitness in healthy older individuals. Eighty-eight men and women (69 ± 3 years, 167 ± 9 cm and 78 ± 14 kg) were randomly placed into four groups: training one- (M1 = 11, W1 = 12), two- (M2 = 7, W2 = 14), or three- (M3 = 11, W3 = 13) times-per-week or a non-training control group (MCon = 11, WCon = 9). During months 1–3, all subjects trained two-times-per-week while during the subsequent 6 months, training frequency was set according to the group. Oxygen consumption (cycling economy: CE), gross efficiency (GE), blood lactate concentrations (…
Effects of Initial Performance, Gross Efficiency and O
2017
The present study investigated the effects of initial levels of cycling performance, peak oxygen uptake (O2peak) and gross efficiency (GE) on the subsequent adaptations of these variables and their relationship following high-intensity training (HIT) designed to increase O2peak in competitive cyclists. Sixty cyclists (O2peak = 61 ± 6 mL kg-1 min-1) were assigned a 12-week training program consisting of twenty-four supervised high-intensity interval training sessions and ad libitum low intensity training. GE was calculated at 125, 175, and 225 W and performance was determined by mean power during a 40-min time-trial (Power40 min). In addition to correlation analyses between initial level and…
Blood and skeletal muscle ageing determined by epigenetic clocks and their associations with physical activity and functioning
2021
AbstractThe aim of this study was to investigate the correspondence of different biological ageing estimates (i.e. epigenetic age) in blood and muscle tissue and their associations with physical activity (PA), physical function and body composition. Two independent cohorts (N = 139 and N = 47) were included, whose age span covered adulthood (23–69 years). Whole blood and m. vastus lateralis samples were collected, and DNA methylation was analysed. Four different DNA methylation age (DNAmAge) estimates were calculated using genome-wide methylation data and publicly available online tools. A novel muscle-specific methylation age was estimated using the R-package ‘MEAT’. PA was measured with q…
