Physical Activity : Absolute Intensity vs. Relative-to-Fitness-Level Volumes
2017
Purpose: This study aimed to investigate in a real-life setting how moderate- and vigorous-intensity physical activity (PA) volumes differ according to absolute intensity recommendation and relative to individual fitness level by sex, age, and body mass index. Methods: A total of 23,224 Finnish employees (10,201 men and 13,023 women; ages 18–65 yr; body mass index = 18.5–40.0 kg·m−2) participated in heart rate recording for 2+ d. We used heart rate and its variability, respiration rate, and on/off response information from R-R interval data calibrated by participant characteristics to objectively determine daily PA volume, as follows: daily minutes of absolute moderate (3–<6 METs) and vigor…
Sustained Adoption of Systematic Physical Activity for Young Elderly : A Developed UTAUT Approach
2020
Health recommendations state that for young elderly systematic physical activi-ties at moderate intensity for at least 150 minutes per week are required to help them stay in good shape for their senior years. We have found that young elderly readily gets started with a physical activity (PA) program but there is some challenge to make them stay with this program. We have learned that a PA program should build on activities that users find meaningful and/or best suited for their history of PA and their present physical capacity. Support from dig-ital services to find meaningful and suitable programs can make a difference. We work out developments of the UTAUT to find drivers that could help …
Skeletal muscle HSP60 expression is fiber-type specific and increases after endurance training
2013
Heat shock protein (Hsp) 60 is primarily localized inside mitochondrial, plays a key role in the translocation of proteins and cytoprotection, and its levels increase in skeletal muscle upon exercise. The purpose of this study was to examine muscle fiber specificity of HSP60 at rest and after an endurance training program of 6 weeks. Forth-eight young (7-weeks old) healthy mice (BALB/c) were subdivided into sedentary and trained groups. Training was performed over a period of 6 weeks on a rota-rod, at a gradually increasing duration and speed. Eight mice of each group were sacrificed after 15, 30 and 45 days. Two days after the last exercise session all mice were sacrificed by cervical disl…

Does Physical Activity Improve Inhibition in Kindergarteners? A Pilot Study
2022
Substantial empirical evidence supports the positive effects of physical activity (PA) on executive functions, but not all forms of physical activity benefit equally. Among kindergarteners, cognitively-engaging exercise seems to more strongly effect EF than simple exercise. We aimed to investigate several qualitatively different exercise formats on kindergarteners' inhibition. Participants were 75 children (M age = 68.1 months), recruited from 14 classrooms of three kindergarten schools. They were randomly assigned to three groups: control group, free play group (non-cognitively-engaging PA), and an intervention group (cognitively-engaging PA). The intervention group performed 18 sessions …
Subjective stress, objective heart rate variability-based stress, and recovery on workdays among overweight and psychologically distressed individual…
2015
Background: The present study aimed to investigate how subjective self-reported stress is associated with objective heart rate variability (HRV)-based stress and recovery on workdays. Another aim was to investigate how physical activity (PA), body composition, and age are associated with subjective stress, objective stress, and recovery. Methods: Working-age participants (n = 221; 185 women, 36 men) in this cross-sectional study were overweight (body mass index, 25.3-40.1 kg/m(2)) and psychologically distressed (>= 3/12 points on the General Health Questionnaire). Objective stress and recovery were based on HRV recordings over 1-3 workdays. Subjective stress was assessed by the Perceived St…
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…
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 …
SuperJump training in eumenorrheic women and gut peptides: a randomized controlled study about the mechanism of action on bone and glucose homeostasis
2022
The role played by physical activity in promoting bone health is now widely recognized. Physical activity limits and slows down the physiological demineralization that occurs over the years and plays an important role in the prevention of osteoporosis. SuperJump, a high-impact training activity performed on a mini-trampoline characterized by alternating between aerobic and anaerobic exercises, has been shown to be able to generate a substantial osteogenic response and increase bone balance and strength in eumenorrheic women. In this study it was analyzed whether gastrointestinal peptides play a role in the regulation of bone metabolism and their impact on glucose homeostasis. Methods Using …
