- Body composition, strength and muscle power indices at the different competitive levels of FutsalPublication . Rebelo, Miguel; Marques, Catarina; Crisóstomo, Rute; Silva Batista, Marco Alexandre; Paulo, Rui; Duarte-Mendes, Pedro; HONÓRIO, SAMUEL; Serrano, JoãoObjective: The aim was to verify the differences in physical condition (body composition, power and muscle strength) in futsal players from three competitive levels. Methodology: Sixty-eight (24.26 ± 4.63 years old) Portuguese futsal players participated in the study, divided into: elite, sub-elite and amateur. We used the bioimpedance, the countermovement jump and the isokinetic dynamometer to assess physical condition, and the Kruskal-Wallis test to compare variables between groups. Results: There were no differences in body composition between groups. Elite players had higher countermovement jump heights than amateur players (p < 0.001). There were significant differences in the isokinetic muscle strength of the knee flexors, with the elite players showing more strength than the amateur players (p = 0.047). Discussion: The results of the research should be contrasted with those of other research found in the literature. Conclusions: The elite players had higher physical condition parameters (more lower limb power and more flexor muscle strength) compared to the amateur players. We would point out that all groups had a high probability of lower limb muscle injury (H/Q ratio < 60%) at this stage of the sports season, alerting training professionals to the importance of individualised physical condition analysis.
- Evaluation Models in Physical Education in PortugalPublication . Santos, Jorge Manuel Folgado; Silva Batista, Marco Alexandre; Rebelo, Miguel; Serrano, João; Petrica, Joao; HONÓRIO, SAMUEL; Marques, Adilson; Gouveia, Élvio RúbioEvaluation in physical education encompasses three stages: initial, formative and summative. The initial assessment diagnoses the level of knowledge and skills of students and can be identified as a starting point. Formative assessment is continuous and occurs throughout the teaching–learning process, providing constant feedback and allowing adjustments in teaching to better meet students’ needs. Summative assessment (final evaluation) occurs at the end of a stage, with the aim of measur‑ ing progress and acquisition of skills throughout the process. They not only measure students’ performance but also guide the development of their physical and cognitive capabilities in a more efficient and personalized context.
- Improving motor competence of children: the “Super Quinas” intervention program in portuguese primary schoolsPublication . Rodrigues, Luis; Cordovil, Rita; Costa, Júlio; Seabra, André;; Guilherme, José; Vale, Susana; Luz, Carlos; Flôres, Fábio; Lagoa, Maria; Almeida, Gabriela; Lopes, Vítor; Mercê, Cristiana; Esteves, Pedro; Santos, Sara; Correia, Vanda; Serrano, João; Mendes, Rui; Matos, Rui; Loureiro, Vânia; Neto, CarlosThe objective of this study was to describe the effects of an extra hour of a structured motor program on the motor competence (MC) of children 6–10 years old.. Design: The need for movement interventions to enhance MC among school-aged children has gained vital importance in the last years, given the negative secular trends reported. Hence, the Portuguese Football Federation organized an intervention program on MC to be implemented on the extracurricular time of the Portuguese primary schools: the Super Quinas program. Methods: Thirty-nine schools from all of Portugal were assigned to intervention and control condition, with a total of 1034 children (6–10 y old) completing all the program (77.7%). The Super Quinas intervention comprised of 1 hour of activity per week, led by a physical educator teacher during extracurricular activities for 12 wees. MC was assessed using the Motor Competence Assessment (MCA) before and at the end of the program (January and April 2023). Normative results of the MCA were used to compare changes between pre and posttest according to experimental or control condition. Results: Results showed a general improvement (P ≤ .001) for all subscales (Locomotor, Manipulative, Stability) and total MCA. More importantly, the experimental group showed significant and positive differences, when compared with the control group, in the Stability (P = .007), Manipulative (P = .015), and total MCA results (P = .018) after controlling for gender, age, and baseline effect. Conclusions: The Super Quinas intervention program proved that adding 1 hour of structured movement program to the regular primary school schedule can lead to greater development of MC in school-age children.
- Profiling external load in U14 basketball: Cluster analysis of competition performance using inertial devicesPublication . Rocha, João; Serrano, João; López-Sierra; Ibáñez, SergioPhysical performance data is essential for planning youth training effectively; however, there is a lack of scientific information regarding performance in youth competitions. To address this gap, an innovative study was conducted with Portuguese U14 regional selections. Each player was equipped with a WimuPro™ inertial device. Six variables were considered: accelerations, decelerations, speed, player load, impacts, and high impacts. The objective of this study, based on data from official competitions, was to statistically analyze the distribution and intensity thresholds of six physical performance variables across five defined zones. A cluster k-means analysis was performed for a significance value of p < 0.05. Five zones were identified for all variables: acceleration [<0.37; 0.37 to 0.81; 0.81 to 1.54; 1.54 to 3.49; >3.49 m/s2], deceleration [<−0.26; −0.27 to −0.63; −0.63 to −1.22; −1.22 to −2.545; >−2.54 m/s2], speed [<5.42; 5.42 to 10.19; 10.20 to 14.63; 14.64 to 18.59; >18.59 km/h2], player load [<1.07; 1.07 to 1.36; 1.37 to 1.63; 1.64 to 1.95; >1.95 u.a./min], impacts [<133.45; 133.45 to 158.75; 158.76 to 181.45; 181.46 to 206.59; >206.59 cont/min], and high impacts [<1.13; 1.14 to 2.11; 2.12 to 3.13; 3.14 to 4.42; >4.42 cont/min]. These intensity zones should be taken into account to optimize training and enhance the understanding of competition in U14 basketball.
