Validity of Hip-worn Inertial Measurement Unit Compared to Jump Mat for Jump Height Measurement in Adolescents
2018
Jump tests assess lower body power production capacity, and can be used to evaluate athletic ability and development during growth. Wearable inertial measurement units (IMU) seem to offer a feasible alternative to laboratory-based equipment for jump height assessments. Concurrent validity of these devices for jump height assessments has only been established in adults. Therefore, the purpose of this study was to evaluate the concurrent validity of IMU-based jump height estimate compared to contact mat-based jump height estimate in adolescents. Ninety-five adolescents (10-13 years-of-age; girls N = 41, height = 154 (SD 9) cm, weight = 44 (11) kg; boys N = 54, height = 156 (10) cm, weight = 4…
Do Adolescents Who Meet Physical Activity Recommendations on Weekdays Also Meet Them on Weekends? A Cross-Sectional Study in Colombia.
2021
The purpose of this study was to examine whether Colombian adolescents fulfill physical activity (PA) recommendations by type of day depending on several variables. A cross-sectional study was carried out on a sample of 2624 adolescents from Neiva (Colombia) using the Seven Day PA Recall and the Family Affluence Scale II self-reported questionnaires. Statistical analyses were performed to find any differences by gender, socioeconomic status, PA recommendations accomplishment, participation in organized and non-organized PA, parents&rsquo
Perceived movement skill competence in stability: Validity and reliability of a pictorial scale in early adolescents.
2021
Perceived motor competence (PMC) is important to health as it mediates the association between actual motor competence (AMC) and physical activity. Many instruments assess the broader construct of physical self-perception but no scale has been developed to assess PMC in stability. The aim of this study was to develop and analyze the reliability and validity of a new pictorial PMC in stability skill assessment when completed by early adolescents. A Delphi method showed ≥70% of experts' consensus in the seven proposed items. A sample of 904 students (11-14 years old) self-reported PMC in locomotion, object control, and stability using two pictorial scales: Perceived Movement Skill Competence …
Psychobiosocial States as Mediators of the Effects of Basic Psychological Need Satisfaction on Burnout Symptoms in Youth Sport
2020
Sport participation in youngsters has been associated with long-lasting psychosocial and health-related benefits as well as increased levels of physical exercise in adulthood. The objective of this study was to examine some psychological factors of fundamental importance in enhancing sport participation and preventing burnout. A sample of 520 girls and boys aged 13–18 years, practicing individual or team sports, took part in a cross-sectional study to assess basic psychological need satisfaction, psychobiosocial states, and burnout symptoms. The specific purpose was to examine the mediation effects of emotion-related (i.e., functional/dysfunctional) psychobiosocial states on the relationshi…

The Father in Youth Baseball: A Self-Determination Theory Approach
2021
This study based on the self-determination theory aims to examine the relationship among the aspirations that fathers have about their children’s youth baseball practice, the children’s basic psychological needs (satisfaction and frustration), and their intentions to either continue or drop out of baseball practice in a sample of children from Hermosillo, Mexico. A cross-sectional study was carried out involving 533 fathers (M = 44.30, SD = 5.18) and 533 children (M = 13.09, SD = 1.68). The results showed that the intrinsic aspirations of fathers were positively correlated to the satisfaction of the children’s psychological needs, whereas the extrinsic aspirations of fathers were positively…
Fundamental movement skills in adolescents : secular trends from 2003 to 2010 and associations with physical activity and BMI
2018
The aim of this study was to examine the secular trends in fundamental movement skills (FMS) among 15- to 16-year-old adolescents at 2 assessment points scheduled in 2003 and 2010 and to investigate the associations between FMS, physical activity (PA), and body mass index (BMI). In 2003, self-reported PA, weight and height, and objective FMS scores were collected from 2390 students, and in 2010, similar data were generated from a second sample of 1346 students. FMS were assessed during both assessment phases using 3 identical objective FMS tests that were figure 8 dribbling, jumping laterally, and coordination track tests. This study indicated that the sum index of FMS did not change among …
Young Athletes' Perceptions of Coach Behaviors and Their Implications on Their Well- and Ill-Being Over Time
2015
Grounded on basic psychological needs theory the purpose of this study was twofold: (a) to test the mediational role of basic psychological needs (satisfaction and thwarting), and (b) to test the model invariance over 2 consecutive seasons. Three hundred sixty young male athletes completed a questionnaire package tapping the variables of interest at 4 time points during 2 consecutive seasons. Results of the path analyses revealed that in both seasons, changes in perceived coach autonomy supportive style positively predicted changes in needs satisfaction which, in turn, positively predicted changes in self-esteem; changes in perceived coach autonomy supportive and controlling style negativel…
Use of the Perceived Physical Competence Scale with Adolescents with Disabilities
1995
The construct validity and reliability of the 1987 Perceived Physical Competence Scale of Lintunen were examined to assess the applicability of the instrument for use with adolescents with disabilities. Subjects were 51 girls and 34 boys ( M age = 15.1 yr.) from several schools in central Finland. Principal component factor analysis with varimax rotation yielded the same two factors for adolescents with disabilities as reported for nondisabled adolescents in the related literature. Cronbach alphas for the two factors were .89 and .56. It was concluded that the scale is an appropriate measure for adolescents with disabilities. Statistical analysis indicated no gender differences for adolesc…
