The fatigue effect of a simulated futsal match protocol on sprint performance and kinematics of the lower limbs.

This study aimed to investigate the fatigue effects induced by a futsal-specific protocol (FIRP) on sprint performance and the kinematics of the lower limbs. Twenty-one futsal players participated in this study and performed a protocol to simulate the futsal demands. At pre-protocol, half-time and post-protocol, the athletes performed 10-m sprints that were recorded for kinematic analysis.

The fatigue effect of a simulated futsal match protocol on isokinetic knee torque production.

The objective of this study was to investigate the effects of a simulated futsal match protocol on isokinetic knee torque production. Twenty-one young futsal players participated in this study and performed a futsal-specific protocol comprising two blocks of 20-minute activities to simulate the match demands. At pre-protocol, half-time, and post-protocol, the concentric and eccentric isokinetic peak torque of the knee flexor and extensor muscles, the angle of peak torque, and the conventional and functional torque ratios were assessed.

Reduction mammoplasty improves body posture and decreases the perception of pain.

Women with hypertrophic breasts often experience body pain and posture problems, which tend to be reduced or even eliminated after reduction mammoplasty. The present study aimed to analyze the effects of reduction mammoplasty on anthropometric variables, body posture and pain in women with breast hypertrophy. Eleven women (mean [± SD] age 31.

Stiffness, intralimb coordination, and joint modulation during a continuous vertical jump test.

This study analysed the modulation of jump performance, vertical stiffness as well as joint and intralimb coordination throughout a 30-s vertical jump test. Twenty male athletes performed the test on a force plate while undergoing kinematic analysis. Jump height, power output, ground contact time, vertical stiffness, maximum knee and hip flexion angles, and coordination by continuous relative phase (CRP) were analysed.

DESCRIPTIVE STUDY ON SAGITTAL LUMBAR SPINE CHANGES IN STUDENTS OF THE FEDERAL EDUCATIONAL SYSTEM OF FLORIANÓPOLIS.

Unlabelled: The purpose of this study was to assess the prevalence of sagittal lumbar spine postural abnormalities and associated factors among students in the federal educational system in Florianópolis.

Methods: 288 adolescents (156 males and 132 females), aged from 15 to 18 years, who were students in the federal educational system in Florianópolis, Santa Catarina, were evaluated. To gather data, photogrammetry was used following a specific protocol for postural assessment, and a questionnaire was used to identify the prevalence and frequency of pain, and the activities that triggered the problem.
