Effect of Preventive Exercise Programs for Swimmer’s Shoulder Injury on Rotator...

Background: Over the season, competitive swimmers experience a progressive imbalance in rotator cuff strength, predisposing them to a significant risk factor for a swimmer’s shoulder injury. Objectives: Verify the effectiveness of two 12-week preventive programs on the shoulder rotators’ peak torque and conventional/functional ratios. Design: A care provider- and participant-blinded, parallel, randomized contro...

Electromyographic activity of shoulder muscles on two preventive exercise progr...

Strength programmes have shown good results in preventing swimmer’s shoulder. However, there aren’t studies based on electromyographic (EMG) analysis in these programmes. This study aims to compare an EMG activity of the middle trapezius (MT), lower trapezius (LT), infraspinatus (IS), serratus anterior (SA), and pectoralis major (PM) in two swimmer’s shoulder preventive programmes – one performed with elastic b...

Comparative Analysis of Pressure Platform and Insole Devices for Plantar Pressu...

Foot plantar pressure refers to the pressure or force that the foot generates in contact with the ground, varying across different regions of the foot. This parameter is essential in static and dynamic analyses to access accurate diagnoses, study the human body biomechanics, create functional footwear designs, aid in rehabilitation and physiotherapy, and prevent injuries in athletes during sports practice. This...

Influence of Jump and Ball Release Parameters on Shooting Accuracy in Basketbal...

Background: This study investigates how both jump-related (jump height and flight time) and ball-related parameters (release height, release angle, and velocity) influence shooting accuracy in basketball under different contextual constraints. Methods: Eighteen senior players competing in the national championship (11 females and 7 males; 22.0 ± 3.7 years) performed 90 shots each across three positions (left 45...

Validação de um questionário sobre o autoconhecimento e perceção dos estudantes...

O desenvolvimento tecnológico e a Inteligência artificial (IA) estão a transformar a forma de ensino-aprendizagem, no ensino superior. Prova disso é o aumento da literatura existente sobre o tema (Chu et al, 2022). A maioria dos estudos incide sobre as características dos instrumentos, do seu uso, benefícios e implementação. A importância da perceção dos estudantes é reconhecida na literatura (Chan & Hu, 2023),...

The Effect of Acute Physical Fatigue on Information Processing, Pain Threshold ...

This study explores the multifaceted effects of acute physical fatigue on information processing, pain threshold, and muscular performance. Enrolling 28 recreational athletes, we used a high-intensity interval training (HIIT) protocol to induce fatigue and conducted pre- and post-intervention assessments. Our findings revealed significant physiological and performance adaptations following the HIIT sessions. Ke...

Postural Control and Muscle Activity during Dual-Task in Young Adults

In everyday life, we recurrently perform two tasks simultaneously, which is called dual-tasking. A common dual task is smartphone use while standing or walking. According to previous studies, this task can compromise postural stability. However, few studies have analyzed lower limb muscle activity during dual-tasking using smartphones. This study aimed to assess the postural sway and muscle activity during dual...

Visual Fixations in Basketball Shooting: Differences between Shooting Conditions

Basketball is a sport where shooting is one of the most important factors that determines the success or failure of the teams. Therefore, basketball players need to shoot the ball accurately. The present study aimed to evaluate whether different shooting conditions influence the visual behavior of athletes. For this, the Tobbi Pro Glasses 3 equipment was used to evaluate the time of the first fixation, the numb...

Muscular and Prefrontal Cortex Activity during Dual-Task Performing in Young Ad...

Postural control depends on attentional resources besides automatic processes. The dual-task paradigm is a possible approach to analyzing the interference and performance between motor and/or cognitive tasks. Various studies showed that, when individuals simultaneously perform two tasks, the postural stability can decline during a dual-task compared with a single-task due to the attentional resources required p...
