Background: Although studies on adolescent girls' disengagement in Physical Education (PE) abound in the literature, most of all investigated root causes only, while few took the initiative to address the inherent issue. Objective: This study primarily aimed at investigating the impact of peer-to-peer feedback interactions on female adolescents' engagement in PE classes, in addition to assessing the potential of video technology in the enhancement of this experience. Methods: A total of 47 Tunisian female students, aged 17 to 18 years, took part in a six-week experiment, during which they went through different long jump learning conditions. A comparative...

Background: The prevalence of childhood obesity is increasing worldwide with its negative health and psychosocial consequences. Research evidence suggests that obesity is strongly associated with low motor competence. In the past two decades, there has been increasing evidence that motor competence is crucial for developing an active and healthy lifestyle. Objective: The purpose of the study was to investigate gross motor coordination in overweight and obese children compared with normal-weight peers. Methods: Data were collected in 326 children (160 boys, 49.1%) aged 7-9 years (mean 8.02, SD 0.81). Their weight status determined by body mass index...

Acta Gymnica 2020, 50(3):113-121 | DOI: 10.5507/ag.2020.015
Background: The numerical inferiority in attacking due to the 2-min penalty is a disadvantageous situation in handball. Teams substitute the goalkeeper with a field player to tolerate this handicap. The rule change enabled the simple practicality of playing with an extra player and an empty net. Objective: The aim of this study is to analyze the effects of intervention on the additional field player strategy in elite national teams. Methods: A total of sixty-two handball matches that were played in the Men's European Handball Championship 2020 were analyzed in this study. We executed a notation analysis on in-game special periods such as the replacement...
The acute effects of one session reactive neuromuscular training on balance and knee joint position sense in female athletes with dynamic knee valgus

Acta Gymnica 2020, 50(3):122-129 | DOI: 10.5507/ag.2020.011
Background: Dynamic knee valgus (DKV) is defined as a combination of excessive femoral adduction, internal rotation, tibial internal torsion, and the medial movement of the knee. It appears that the athletes with DKV are at higher risk of developing knee injuries. Objective: The aim of this study was to evaluate whether the reactive neuromuscular training would improve whole-body dynamic balance and knee joint position sense (JPS) in women with the dynamic knee valgus. Methods: A controlled laboratory study was conducted on 28 female athletes with DKV. The single leg squat test was used to assess the DKV. All participants performed the reactive neuromuscular...

Acta Gymnica 2020, 50(3):130-137 | DOI: 10.5507/ag.2020.013
Background: There is a lack of descriptive data available regarding the characteristics of female soccer players from the African continent or the Arab world. Objective: This study investigated the anthropometric and physical fitness profiles of Tunisian female soccer players in relation to field position. Methods: In all, 75 Tunisian sub-elite female soccer players, with an average of 4.3 ± 1.6 years of playing experience, including goalkeepers (GK; n = 11), central defenders (CD; n = 13), external defenders (ED; n = 15), central midfielders (CM; n = 10), external midfielders (EM; n = 14), and attackers (AT; n = 12), underwent anthropometric...
