The purpose of this study was to determine the differences in functional capacities and hormonal indices according to biological maturity and seasonal playing time status in young soccer players. Twenty-three male under-15 players (14.6 +/- 0.2 years) were divided into two groups, based on their maturity status and seasonal playing time. They were measured for anthropometrics, Yo-Yo intermittent recovery level 1 (YYIR1), seven repeated sprint test (7RST), countermovement jump (CMJ), skeletal age, growth hormone, and insulin-like growth factor-1 (IGF-1) level. Age at peak height velocity (APHV) was determined to estimate the maturity timing. The results revealed that players who advanced in maturation were significantly heavier (p = 0.029) and had higher values in skeletal age (p < 0.001), sitting height (p = 0.005), CMJ (p = 0.038), and IGF-1 (p = 0.013). Players given greater playing time exhibited significantly lower fatigue index (p = 0.012), but higher CMJ (p = 0.003) and IGF-1 (p = 0.001) values. The overall results highlighted that early-maturing players and players with greater playing time obtained higher values in both CMJ and IGF-1. The findings may provide an insight on the coaches' evaluation of players and on the possible factors that may affect the future playing status of young male soccer players.

The relationship of self-concept and perceived athletic competence to physical activity level and gender among Turkish early adolescents
Asci, FH; Kosar, SN; Isler, AK (2001-09-01)
The purpose of this study was to examine the self-concept and perceived athletic competence of Turkish early adolescents in relation to physical activity level and gender. Self-concept was assessed using the Piers-Harris Children's Self-Concept Scale, and perceived athletic competence was assessed by means of the Athletic Competence subscale of Harter's Self-Perception Profile for Children. In addition, the Weekly Activity Checklist was used for assessing physical activity level. Males and females were assi...

THE EFFECTS OF COVID-19 INDUCED MOBILITY RESTRICTIONS ON PHYSICAL FITNESS IN YOUNG SOCCER PLAYERS AT DIFFERENT MATURITY AND TRAINING STATUS
Ünlü, Gürcan; Söğüt, Mustafa; Department of Physical Education and Sports (2022-2-10)
The purpose of this study was to examine the 27-week COVID-19 induced mobility restrictions on physical fitness in young soccer players at different maturity and training status. The 52 participants were categorized into highly trained (HT, n=27) and recreationally trained (RT, n=25) players. HT consists of sixteen pre-PHV and eleven mid-PHV, RT consists of fifteen pre-PHV and ten mid-PHV players. After measuring anthropometrics, the following selected physical fitness tests were performed: handgrip strengt...
