Acute effects of different foam rolling volumes in the interset rest period on maximum repetition performance
2017
Background - Foam rolling (FR) is a ubiquitous intervention utilised for the purpose of acutely increasing the range of motion without subsequent decreases in performance. Thus, it is commonly used during the periworkout period—that is, prior to, during, or after an athlete's workout.\ud \ud Objective - This study investigated how different FR durations applied to the quadriceps during the interset rest periods affects the numbers of repetitions in the knee extension exercise.\ud \ud Methods - Twenty-five females completed four sets of knee extensions with 10 repetitions of maximum load to concentric failure on four occasions. Between each set, a 4-minute rest interval was implemented in wh…
Influence of Guideline Operationalization on Youth Activity Prevalence in the International Children's Accelerometry Database
2022
Introduction: The United Kingdom and World Health Organization recently changed their youth physical activity (PA) guidelines from 60 minutes of moderate-vigorous PA (MVPA) every day, to an average of 60 minutes of MVPA per day, over a week. The changes are based on expert opinion due to insufficient evidence comparing health outcomes associated with different guideline definitions. Further, inconsistent guideline operationalization impairs understanding of physical inactivity prevalence. This study used the International Children’s Accelerometry Database to compare approaches to calculating PA compliance among youth and associations with health indicators. Methods: Cross-sectional accelero…
Participation in organized sports is associated with decreased likelihood of unhealthy lifestyle habits in adolescents
2018
Adolescence is a pivotal time for investing in both present and future health. Thus, it is important to identify arenas for promoting positive adolescent health behaviors and preventing negative ones. The aim of this study was to investigate the associations between organized sports participation (OSP) and a broad range of lifestyle habits in Norwegian adolescents. A comprehensive survey was completed by 13 269 junior high and high school students in southern Norway. Multivariable binary logistic regression models, adjusted for gender, age, and parental education, were used to investigate the associations between OSP and adolescent substance use, dietary habits, physical activity level, pas…
Transition from Youth categories to Elite cycling: relationships between early career performance and UCI World Tour success
2021
BACKGROUND The present study aimed to describe the possible roles of cyclists' early career performance, on the transition process to elite cycling categories. METHODS Data from national and international databases, and results achieved during the UCI World Championships, were retrospectively analysed considering the Italian national Youth-U16, Junior-U18, and U23 categories, and international Junior-U18 and UCI World-Tour categories. RESULTS The 15% of Youth-U16, the 38.8% of Junior-U18 and the 60% of U23 athletes who ranked top-10 between 2007 and 2013, scored points in UCI World Tour competitions between 2012 and 2018. The 1.6% of Youth-U16, the 8.3% of Junior-U18 and 25% of U23 athletes…
Inter-individual variation in response to resistance training in cardiometabolic health indicators.
2020
Resistance training (RT) may improve metabolic health; however, the extent of its effectiveness is constantly evaluated to assess improvements in the group means, thus obscuring the heterogeneous individual effects. This study investigated inter-individual variation in response to RT as reflected in metabolic health indicators and how age, sex, nutrition, and pre-training phenotypes are associated with such variabilities. Methods Previously collected data of men and women (39-73 years, 135 trained, 73 non-trained controls) were pooled for analysis. Measurements were taken twice before training to estimate individual day-to-day variations and measurement errors (n = 208). The individual resp…
Physical Activity, Fitness, Glucose Homeostasis, and Brain Morphology in Twins
2014
The main aim of the present study (FITFATTWIN) was to investigate how physical activity level is associated with body composition, glucose homeostasis, and brain morphology in young adult male monozygotic twin pairs discordant for physical activity.From a population-based twin cohort, we systematically selected 10 young adult male monozygotic twin pairs (age range, 32-36 yr) discordant for leisure time physical activity during the past 3 yr. On the basis of interviews, we calculated a mean sum index for leisure time and commuting activity during the past 3 yr (3-yr LTMET index expressed as MET-hours per day). We conducted extensive measurements on body composition (including fat percentage …
Associations of Maximal Strength and Muscular Endurance with Cardiovascular Risk Factors
2013
The aim was to study the associations of maximal strength and muscular endurance with single and clustered cardiovascular risk factors. Muscular endurance, maximal strength, cardiorespiratory fitness and waist circumference were measured in 686 young men (25±5 years). Cardiovascular risk factors (plasma glucose, serum high- and low-density lipoprotein cholesterol, triglycerides, blood pressure) were determined. The risk factors were transformed to z-scores and the mean of values formed clustered cardiovascular risk factor. Muscular endurance was inversely associated with triglycerides, s-LDL-cholesterol, glucose and blood pressure (β=-0.09 to - 0.23, p0.05), and positively with s-HDL choles…
Tactical Aspects of a National University Taekwondo Championship in Relation to Round and Match Outcome
2015
The aims of this study were to analyze tactical behavior (direct attacks and indirect attacks, in addition to anticipatory, simultaneous, and posterior counterattacks) according to competition round and match, and to compare tactics of competitors (winners and nonwinners) in a university taekwondo championship. The analysis included 334 individual performances from 204 athletes over 169 bouts in the National University Championship. A 2-way repeated measure analysis of variance was conducted with “round” (at 3 levels: first, second, and third) as the within-subject factor and match outcome (at 2 levels: winning and nonwinning) as the between-subject factor. The results of this study show th…
Parental Support and Objectively Measured Physical Activity in Children: A Yearlong Cluster-Randomized Controlled Efficacy Trial
2017
ABSTRACTPurpose: We studied whether physical activity (PA) counseling for parents influenced the level of parental support of children’s PA and leisure-time PA in children of different levels of initial parental support. We hypothesized that the initial level of parental support would moderate the intervention efficacy. Method: Children (n = 44, Mage = 6.09 ± 1.17 years) and their parents (n = 61) randomly assigned to an intervention group received counseling for 6 months. Children in the control group (n = 47, Mage = 6.12 ± 1.11 years) and their parents (n = 63) did not receive any counseling. Parental support was assessed using the Family Physical Activity Environment Questionnaire, and c…
Muscle Inactivity and Activity Patterns after Sedentary-Time Targeted Randomized Controlled Trial
2014
Purpose: Interventions targeting sedentary time are needed. We used detailed EMG recordings to study the short-term effectiveness of simple sedentary time-targeted tailored counseling on the total physical activity spectrum. Methods: This cluster randomized controlled trial was conducted between 2011 and 2013 (InPact, ISRCTN28668090), and short-term effectiveness of counseling is reported in the present study. A total of 133 office workers volunteered to participate, from which muscle activity data were analyzed from 48 (intervention, n = 24; control, n = 24). After a lecture, face-to-face tailored counseling was used to set contractually binding goals regarding breaking up sitting periods …
