Organized Sport Participation and Physical Activity Levels among Adolescents with Functional Limitations
2017
Sufficient and regular physical activity is considered a protective factor, reducing the onset of secondary disability conditions in adolescents with chronic diseases and functional limitations. The aim of this study was to explore whether participation in organized sport may be associated to higher levels of physical activity in adolescents with functional limitations, based on a national representative sample. Data from the Health Behaviour in School-aged Children (HBSC) study collected in Finland from two data collection rounds (2002 and 2010) were conducted and pooled from adolescents aged between 13 and 15 years old with functional limitations (n = 1041). Differences in self-reported p…
Acute Endocrine and Force Responses and Long-Term Adaptations to Same-Session Combined Strength and Endurance Training in Women
2015
This study examined acute hormone and force responses and strength and endurance performance and muscle hypertrophy before and after 24 weeks of same-session combined strength and endurance training in previously untrained women. Subjects were assigned 1 of 2 training orders: endurance preceding strength (E + S, n = 15) or vice versa (S + E, n = 14). Acute force and hormone responses to a combined loading (continuous cycling and a leg press protocol in the assigned order) were measured. Additionally, leg press 1 repetition maximum (1RM), maximal workload during cycling (Wmax), and muscle cross-sectional area (CSA) were assessed. Loading-induced decreases in force were significant (p < 0.01–…
Relative age and perceptions of soccer specific skills among elite youth players in Norway
2019
One common feature among the selected players in talent development programs are the well-known relative age effect (RAE), characterized by a skewed birth distribution among selected players with an over-representation of players born early in the selection year. The aim of the present study was to examine potential differences in soccer-specific skills between players selected for national talent program born in the first half of the year compared to the players born in the second half of the year. A total of 753 elite male U 14 (N = 363) and U 13 players (N = 390) from 16 of 18 soccer regions in Norway participated. The results showed players born early in the selection year considered th…
La investigación cualitativa en las revistas españolas de ciencias del deporte (2007-2011)
2015
El objetivo de este estudio fue determinar el estado de la investigación cualitativa en las ciencias de la actividad física y del deporte en España, a partir del análisis de 1057 artículos publicados entre 2007 y 2011 en revistas españolas del campo indexadas en Scopus. Los resultados indican que sólo el 3.5% de los trabajos recurre a la metodología cualitativa y que en su mayor parte utilizan la entrevista como técnica de recogida de datos. Se señala como conclusión que la investigación cualitativa en las ciencias de la actividad física y el deporte en España se encuentra todavía en estado embrionario. The aim of this study was to determine the status of qualitative research in sport scien…

Previous research indicates that programmes employing Hellison’s Teaching Personal and Social Responsibility (TPSR) model in physical activity have had a positive impact on youth development by inc...
Running in highly cushioned shoes increases leg stiffness and amplifies impact loading
2018
AbstractRunning shoe cushioning has become a standard method for managing impact loading and consequent injuries due to running. However, despite decades of shoe technology developments and the fact that shoes have become increasingly cushioned, aimed to ease the impact on runners’ legs, running injuries have not decreased. To better understand the shoe cushioning paradox, we examined impact loading and the spring-like mechanics of running in a conventional control running shoe and a highly cushioned maximalist shoe at two training speeds, 10 and 14.5 km/h. We found that highly cushioned maximalist shoes alter spring-like running mechanics and amplify rather than attenuate impact loading. T…
Practice effects on visuomotor and problem-solving tests by children.
2001
Practice effects on a visuomotor test (the Developmental Test of Visuo-Motor Integration), a timed visual discrimination test (the Underlining Test), and two problem-solving tests (the Porteus Mazes Test and the Tower of Hanoi Test) were analyzed. Children of two age groups ( Ms: 7.7 and 11.6 yr.) were chosen to study the effect of age on practice effects. The tests were repeated nine times with test-retest intervals of 2 mo. The Developmental Test of Visuo-Motor Integration showed no practice effects, while the Porteus Mazes Test, the Underlining Test, and the Tower of Hanoi Test showed significant practice effects. Practice effects were larger for the older age group on all the tests, ex…
MRI findings and physical performance as predictors of flight-induced musculoskeletal pain incidence among fighter pilots
2017
Summary Study aim: The aim of this study was to evaluate the possible association of pre-career magnetic resonance imaging (MRI) findings and physical performance level with possible musculoskeletal disorders during jet flight training. Material and methods: The study group consisted of 73 fighter pilots who had undergone pre-career cervical and lumbar spine MRI. Physical performance of a subgroup of the pilots (n = 67) was measured initially at the same time and followed up to the fast jet training phase (ranging from 3.8 to 7.0 years). Musculoskeletal pain history during pilot training was taken from the medical charts. MRI findings and physical performance were associated with perceived…
Physical activity and laryngeal cancer
2019
Although an active lifestyle physical has been convincingly associated with a decreased risk of developing many forms of cancers, including neck and head malignancies, uncertainty surrounds the relationship between physical activity (PA) and laryngeal carcinogenesis. Epidemiologic evidence, garnered from some well-conducted cross-sectional, prospective and retrospective studies, seemingly attests that the impact of PA may be not so straightforward in lowering laryngeal cancer risk as for other malignancies. Reasonable consensus has been reached that moderate-intensity PA may generate the larger potential benefits, whilst the effect of high-intensity PA appears more controversial and even co…
Comparison of Physical Activity and Sedentary Behaviour between Schoolchildren with Cystic Fibrosis and Healthy Controls: A Gender Analysis
2021
The purpose of this study was to examine differences in sports participation and the levels of physical activity (PA) and sedentary behaviour (SB) between schoolchildren with cystic fibrosis (CF) and a healthy control group (CG) taking into account the gender variable. PA and SB were measured with an accelerometer for 7 consecutive days in 44 children (24 girls
