Adolescents with traumatic brain injury (TBI) are often discharged from physical therapy (PT) services without transitioning into exertional conditioning programs. Active participation in physical activities with peers at school is essential to achieve a sense of accomplishment and acceptance. Factors such as reduced aerobic fitness and residual gait impairments can lead to limited participation and peer interaction. The purpose of this case report was to describe the impact of home-based circuit training (HBCT) focusing on strength and balance on gait speed (GS), energy expenditure, and functional performance in a 17-year-old female with severe TBI...

Sprint performance is an important characteristic for success in many sports, including rugby union. Resistance training is used to increase muscular fitness (i.e. strength, endurance and power) and may also be effective for improving sprint and jump performances. The aims of this study were to examine the effects of resistance training using two different periodized programs (linear and daily undulating) on sprint and jump performance and explore relationships between performance measures. Sixteen male (16...

Numerous national associations and multiple reviews have documented the safety and efficacy of strength training for children and adolescents. The literature highlights the significant training-induced increases in strength associated with youth strength training. However, the effectiveness of youth strength training programs to improve power measures is not as clear. This discrepancy may be related to training and testing specificity. Most prior youth strength training programs emphasized lower intensity resistance with relatively slow movements...

Though the plasticity of human tendons is well explored in adults, it is still unknown how superimposed mechanical loading by means of athletic training affects the properties of tendons during maturation. Due to the increased responsiveness of muscle to mechanical loading, adolescence is an important phase to investigate the effects of training on the mechanical properties of tendons. Hence, in the present study we compared vastus lateralis (VL) architecture, muscle strength of the knee extensor muscles and patellar tendon mechanical properties of male and female adolescent elite athletes to untrained boys and girls...
