The purpose of this study was to investigate the effects of a 12-week resistance-training program on muscle strength and mass in older adults. Thirty-three inactive participants (60-74 years old) were assigned to 1 of 3 groups: high-resistance training (HT), moderate-resistance training (MT), and control. After the training period, both HT and MT(More)
The aim of this study was to examine differences between experts and novices in a number of perceptual abilities. Three groups of elite athletes, 44 members of Greek national teams in basketball (n = 12), volleyball (n = 13), and water-polo (n = 19) were selected. Two groups of physical education students (ns = 18 and 21) were novices. The measured(More)
The aim of this study was to examine the contextual interference effect on learning three volleyball skills. Participants were 26 novice female volleyball players (M age= 12.4 yr., SD= 1.2). They were assigned into two groups, Low Interference (n = 13) and High Interference (n = 13). Two practice schedules were used: blocked (Low Interference) and random(More)
OBJECTIVE To investigate the relationships between physical, psychosocial, and individual characteristics and occurrence, chronicity, care seeking and absenteeism due to musculoskeletal complaints of the lower back and knee. METHODS AND PARTICIPANTS This was a cross-sectional study among 350 nursing personnel in six hospitals in South-West Greece. Data(More)
This study determined dietary intake and energy balance of elite premenarcheal rhythmic gymnasts during their preseason training. Forty rhythmic gymnasts and 40 sedentary age-matched females (10-12 yrs) participated in the study. Anthropometric profile and skeletal ages were determined. Dietary intake and physical activity were assessed to estimate daily(More)
UNLABELLED The aim of this study was to examine the relationship between motor proficiency and pedometer-determined physical activity in 5-6 year-old children. Participants (n = 232) were randomly recruited and assessed from 30 kindergartens in Northern Greece. Two trained researchers administered the measurements for the assessment of children's motor(More)
The purposes of this study were to record the injury incidence in all age categories of female volleyball players and to clarify the role of age in injury occurrence. The injury incidence rate, severity, diagnosis and the anatomical location of the injuries, which occurred during practice and competition during the championship period, were recorded(More)
The purpose of this study was to determine the effect of participation in a community-based sport skills learning programme on reported physical activity (PA), daily step counts and fitness levels of children aged 10–12 years. Participants in this study were 119 students, 59 girls (age 11.02±0.8 years, mean±SD) and 60 boys (age 11.2±0.9 years), from the(More)
The main purpose of this study was the identification of the current pedometer determined physical activity levels of a large sample of 9 -14 years old Greek schoolchildren and the determination of the association between daily step counts and body mass index through the comparison of step counts among overweight, obese and normal-weight children. A total(More)
OBJECTIVE To determine the relationship between habitual physical activity (PA) level and peripheral qualitative computed tomography-determined quantitative tibia characteristics of premenarcheal girls. METHODS Premenarcheal girls matched for age (10-13 years), bone age and maturity level were assigned into: a) low PA group (LPA, n=25), b) moderate PA(More)
