Study Design: Cross-sectional study.

Objectives: To compare cardiac autonomic modulation of individuals with spinal cord injury (SCI) that practice different amounts of moderate to vigorous physical activity (PA) and able-bodied controls at rest and during a non-immersive Virtual Reality task.

Setting: Athletes with SCI of wheelchair basketball, wheelchair tennis, wheelchair handball, WCMX (wheelchair motocross), and para-swimming were assessed at the Faca na Cadeira Institute, ICEL and Clube Espéria in São Paulo, Brazil; non-athletes with SCI and able-bodied controls were assessed at the Acreditando Centro de Recuperação Neuromotora, São Paulo, Brazil.

The objective of this study was to compare the brake response time of drivers with paraplegia (who use hand control) with drivers without paraplegia (who use their feet) in a virtual driving simulator brake test. Additionally, we aimed to predict and evaluate the association of virtual brake response time with sociodemographic, motor and cognitive variables. 40 male adult drivers, with paraplegia (n = 20, mean age 38.

This study aimed to investigate the association between the optimum power load in the bench press (BP), shoulder press (SP), and prone bench pull (PBP) exercises and acceleration (ACC) and speed performances in 11 National Team wheelchair basketball (WB) players with similar levels of disability. All athletes were previously familiarized with the testing procedures that were performed on the same day during the competitive period of the season. First, athletes performed a wheelchair 20-m sprint assessment and, subsequently, a maximum power load test to determine the mean propulsive power (MPP) in the BP, SP, and PBP.

Purpose: To evaluate the effects of inspiratory muscle training associated with interval training on respiratory muscle strength and fatigue and aerobic physical performance (PP) in high-performance wheelchair basketball athletes.

Methods: Blinded, randomized clinical trial with 17 male wheelchair basketball players, randomized into control group (CG; n = 8) and training group (TG; n = 9). Respiratory muscle strength was evaluated by measuring maximal inspiratory and expiratory pressures (MIP and MEP), aerobic PP by the Yo-Yo test for wheelchair, and recovery of inspiratory muscle fatigue was assessed at 1, 5, 10, and 15 minutes after exercise test.

Objectives: This study sought to analyze the extent of motor adaptation in ankle plantar flexors and dorsiflexors among older drivers during clinical isokinetic testing.

Methods: One hundred older adults (70.4±5.

Objective: The aims of this study were (1) to identify differences in trunk muscle strength and balance among various classes of wheelchair basketball (WCB) players and (2) to determine if trunk muscle strength and balance correlate with the current observation-based classification of WCB players.

Design: Isometric trunk strength and balance (limits of stability) were objectively quantified in 42 male WCB players. Principal component analysis was used to synthesize a battery of strength and balance measures into a single, composite score of trunk function.

Objective: The aim of the present study was to evaluate the influence of anthropometric characteristics and gender on postural balance in adults. One hundred individuals were examined (50 males, 50 females; age range 20-40 years).

Methods: The following body composition measurements were collected (using bone densitometry measurements): fat percentage (% fat), tissue (g), fat (g), lean mass (g), bone mineral content (g), and bone mineral density (g/cm²).
