The well established guidelines for developing speed and power in younger athletes may not apply to masters athletes due to a number of age-related changes in muscle morphology and neural factors affecting speed and power. These age-related changes include decreased muscle mass, a decrease in type II muscle fibre size, and decreased neural activation of muscle. These age-related declines strongly suggest concurrent sprint and resistance training may be required to improve speed and power in masters athletes. However, limited research has examined the impact of concurrent sprint and resistance...
