Article Synopsis
- The study aimed to assess the reliability of swimming performance tests in both dry-land and water scenarios, and to examine the occurrence of significant differences between limbs in swimmers.
- Twenty-eight swimmers completed various physical tests twice, a week apart, and researchers measured how consistent the results were over time using specific statistical methods.
- Most tests showed good reliability, except for shoulder range of motion, and some athletes had meaningful limb asymmetries, indicating potential areas for improvement in their training.
Functional Fitness Training (FFT) is a very popular training method in recent years. However, the combination of aerobic and strength components of this training method raised the hypothesis of impaired strength and muscle structure when compared to Strength Training (ST). Thus, the study aimed to compare muscle architecture and strength between FFT and ST, and the relationship between muscle architecture and maximum strength performance.

The sample was composed of 14 manual wheelchair users (four women, 10 men). The peak torque of the elbow flexors and extensors were measured on the dominant and non-dominant limbs, using a set of concentric/eccentric contractions at speeds of 60° s and 180° s.

- Landing is crucial for injury prevention, where equal use of lower limbs helps absorb shock, but fatigue may cause imbalances.
- The study involved 15 active men who performed a fatigue protocol with vertical jumps and assessed lower limb asymmetry through ground reaction force, leg stiffness, and coordination during a landing task.
- Results showed that while fatigue did not significantly impact asymmetry indexes overall, moderate effects were noted on peak ground reaction force and leg stiffness immediately after the fatigue protocol.
Background: Body composition is relevant for the health and work performance of firefighters. However, the behavior of these parameters has not been elucidated for groups of firefighters performing different tasks.
Objectives: To compare the anthropometric profile of military firefighters who perform administrative (ADM) or operational work .
