Physical fitness, hormonal, and immunological responses during prolonged military field training
2018
Physical fitness is crucial to warfighters’ performance in the battlefield. Previous studies have shown negative changes in their hormonal and neuromuscular responses induced by military field training (MFT). The purpose of this study was to investigate the changes in hormonal and immunological values and body composition during a prolonged MFT and to find out how warfighters’ physical condition influences these changes. Conscripts (n = 49, age 20 1 years, height 179 9 cm, body mass 73.8 7.8 kg, fat 12.6 3.7% and BMI 23 kg/m²) were measured before, during, after MFT, and after a 4-day recovery period. Serum insulin-like growth factor-1 (IGF-1), tumor necrosis factor alpha (TNF-a), interleuk…
Long-term health-related quality of life of breast cancer survivors remains impaired compared to the age-matched general population especially in you…
2021
Objective To investigate long-term health-related quality of life (HRQoL) changes over time in younger compared to older disease-free breast cancer survivors who participated in a prospective randomized exercise trial. Methods Survivors (aged 35–68 years) were randomized to a 12-month exercise trial after adjuvant treatment and followed up for ten years. HRQoL was assessed with the generic 15D instrument during follow-up and the younger (baseline age ≤ 50) and older (age >50) survivors’ HRQoL was compared to that of the age-matched general female population (n = 892). The analysis included 342 survivors. Results The decline of HRQoL compared to the population was steeper and recovery slower…
A healthy Nordic diet and physical performance in old age : findings from the longitudinal Helsinki Birth Cohort Study
2016
AbstractEpidemiological studies have shown that a number of nutrients are associated with better physical performance. However, little is still known about the role of the whole diet, particularly a healthy Nordic diet, in relation to physical performance. Therefore, we examined whether a healthy Nordic diet was associated with measures of physical performance 10 years later. We studied 1072 participants from the Helsinki Birth Cohort Study. Participants’ diet was assessed using a validated 128-item FFQ at the mean age of 61 years, and a priori-defined Nordic diet score (NDS) was calculated. The score included Nordic fruits and berries, vegetables, cereals, PUFA:SFA and trans-fatty acids ra…
The assessment of scales of frailty and physical performance improves prediction of major adverse cardiac events in older adults with acute coronary …
2019
Abstract Background The number of older adults admitted to hospital for acute coronary syndrome (ACS) has increased worldwide. The aim of this study was to determine which scale of frailty or physical performance provides incremental improvements in risk stratification of older adults after ACS. Methods A prospective cohort of 402 older (≥70 years) ACS patients were enrolled. Data about baseline characteristics, Global Registry of Acute Coronary Events (GRACE), and Thrombolysis in Myocardial Infarction (TIMI) risk scores were collected. Before hospital discharge, seven scales of frailty and physical performance were measured. The 1-year occurrence of adverse events (cardiac death, reinfarct…
Infant and childhood growth and frailty in old age : the Helsinki Birth Cohort Study
2018
BackgroundEvidence from life course studies highlights the importance of infant and childhood growth as risk factors for adulthood chronic diseases.MethodsIn this sub-study of the Helsinki Birth Cohort Study, we studied 1078 individuals who had both information on body size from birth to 12 years of age and who were assessed for frailty according to the Fried criteria at the mean age of 71 years.ResultsGreater BMI gain between 2 and 11 years in boys was associated with frailty in old age (age-adjusted RRR 2.36, 95% CI 1.21, 4.63). No similar associations were observed in girls.ConclusionsMen who were frail in old age experienced accelerated BMI gain in childhood compared with those men who …
Objectively measured physical activity and physical performance in old age
2017
Abstract Background: Physical performance is a key factor that determines how older people cope with daily tasks and maintain independency. There is strong evidence suggesting that physical activity (PA) is important in maintaining physical performance in old age. However, most studies have been done using self-reported PA. Our aim was to explore the association between objectively measured PA and physical performance in old age. Methods: We studied 695 participants (mean age 70.7 years, SD 2.7) from the Helsinki Birth Cohort Study. Physical performance was assessed with the Senior Fitness Test (SFT) and PA with a multisensory activity monitor SenseWear Pro 3 Armband. Results: Total volume …
Plantarflexor Muscle-Tendon Properties are Associated With Mobility in Healthy Older Adults
2015
BACKGROUND: Muscle mass, strength, and power are known determinants of mobility in older adults but there is limited knowledge on the influence of muscle architecture or tendon properties on mobility. The purpose of this study was to examine the relationship between mobility and plantarflexor muscle-tendon properties in healthy older adults.METHODS: A total of 52 subjects (age 70-81 years) were measured for 6-minute walk test (6MWT), timed "up and go"-test (TUG), isometric plantarflexion strength, Achilles tendon stiffness, triceps surae muscle architecture, lower extremity lean mass, isometric leg extension strength, and leg extension power. Partial correlations and multivariate regression…
Individual Scaling of Accelerometry to Preferred Walking Speed in the Assessment of Physical Activity in Older Adults
2020
Abstract Background Walking forms a large portion of physical activity (PA) of older adults. We assessed free-living PA using acceleration corresponding to preferred walking speed as a relative cut-point and studied how it relates to age. We compared the relative cut-point to a common absolute cut-point of moderate-to-vigorous physical activity (MVPA). Method Four hundred forty-four community-dwelling adults aged 75, 80, and 85 years wore an accelerometer on the thigh during a PA surveillance period and a modified 6-minute walking test (6MWT) at preferred speed. Each individual’s mean acceleration (g) during the 6MWT was used as a cut-point for relative PA. Acceleration corresponding to thr…
Association Between Short Physical Performance Battery and Falls in Older People: The Progetto Veneto Anziani Study.
2014
It is known that weakness in the lower limbs is associated with recurrent falls in old people. Among the tests routinely used to assess lower extremity strength, the Short Physical Performance Battery (SPPB) is one of those used most often, but its relationship with recurrent falls is poorly investigated. We aimed to determine if SPPB scores are related to recurrent falling in a sample of 2710 older-aged people, and to ascertain which test in the SPPB is most strongly associated with a higher rate of falls. In this cross-sectional study, we demonstrated that participants scoring 0-6 in the SPPB were more likely to be recurrent fallers than those scoring 10-12 (odds ratio [OR]=3.46, 95% conf…
The effect of body mass index, lower extremity performance, and use of a private car on incident life-space restriction: a two-year follow-up study
2018
Background: The purpose of the study was to explore the single and combined contributions of body mass index (BMI) and lower extremity performance as modifiable physical factors, and the influence of use of a private car as an environmental factor on prevalent and incident life-space restriction in community-dwelling older people. Methods: Community-dwelling people aged 75–90 years (n = 823) participated in the Life-Space Mobility in Old Age (LISPE) two-year follow-up study. Participants who reported that the largest life-space area they had attained, without aid from any device or another person, was the neighborhood or less were considered to have life-space restriction. Incident life-spa…
