VOLUMES NO QUOTIDIANO: O USO DE MATERIAIS CONCRETOS E MANIPULÁVEIS NO ENSINO DE...

This study, conducted with 18 sixth-grade students (ages 11–12), investigated how the use of Base Ten Blocks (MAB) and the connection between mathematics and everyday life contribute to the understanding of the concept of volume. The main objectives were: to promote the construction of the volume concept using MAB; to implement tasks contextualized in students’ daily lives; and to analyze the impact of manipula...

Lower body strength and body composition in female football

Lower-body strength plays a crucial role in football performance and injury prevention, and thus, monitoring of strength variables has become crucial in the training process. This study aims to (1) assess knee muscle strength performance through intra- and inter-limb asymmetries and (2) examine the relationships between knee muscle strength, body composition, and vertical jump performance (squat jump and counte...

Four-year associations of wish-to-die trajectories with changes in the frailty ...

Background: A death wish is a passive ideation about thoughts that suggest dying is better than continuing to live. We investigated the associations of different wish-to-die (WTD) trajectories with changes in frailty over a four-year period in European citizens aged 50 and over. Methods: A longitudinal analysis was conducted with 27,350 participants (13,921 women) from 17 European countries, all aged ≥50 years,...

Knee and hip muscle strength of professional football players from different co...

In football, knee and hip muscle strength assessment have been recommended for injury prevention (Mosler et al., 2017; Namazi et al., 2019). Additionally, bilateral strength differences in the knee and hip joints have been related to an increased risk of injury. The aims of this study were threefold: (1) to compare knee and hip muscle strength performance between professional players competing at different leve...

Sports injuries of a Portuguese professional football team: a 3-year longitudin...

Football is known for its fast-paced and intensive activities from a professional standpoint, exposing professional football players to a high injury risk across their sportive careers. This study aimed to describe and characterise the sportive injuries of a First Portuguese Football League professional football team over three consecutive seasons. Seventy-one male professional football players (age = 25.7 ± 3....

Lower limbs strength variations between injured and non-injured professional so...

<jats:p> Due to its physical demands, professional soccer is becoming a real challenge regarding players’ exposure to high injury risk. Given its tight correlation with high-intensity actions, muscular strength is a crucial physical characteristic for soccer players. Therefore, the aims of this study are (a) to compare the vertical jumping performance during the season according to the injury profile, and (b) t...

Lower-body power, body composition, speed, and agility performance among youth ...

Speed and agility have been described as crucial abilities for soccer players. The purpose of this study was to analyze, in detail, the variance in speed and agility tasks explained by lower-body power after controlling for age and body composition. The participants were 96 male soccer players aged 16.1 ± 1.6 years. Body composition (stature, body fat percentage-BF%, body mass, and fat-free mass-FFM), lower-bod...

Changes in Estimated Body Composition and Physical Fitness of Adolescent Boys a...

Sports participation is one of the most popular forms of physical activity among youngsters. This study aimed to examine the changes in the estimated body composition, strength, and flexibility of adolescent boys after 12 months of soccer training compared with those of age-matched controls with non-sports participation. We assessed 137 boys (62 soccer players and 75 controls) at baseline (TM1) and 12 months la...

Characterization of Static Strength, Vertical Jumping, and Isokinetic Strength ...

Muscular strength is strongly related to speed and agility tasks, which have been described as the most decisive actions preceding goals in the soccer game. This study aimed to characterize the players' strength indicators and to analyze the variation associated with age, competition level, and positional role. Eighty-three male soccer players from A team (n = 22), B team (n = 17), U-23 (n = 19), and U-19 (n = ...
