Running Fitness - Run Speed for Android
While running of course requires and develops excellent cardiovascular fitness and lung capacity, efficient running also requires good biomechanics, mobility, stride quality and a good strength to weight ratio.
Long runs, short runs, sprints and intervals performed at different intensity levels will help develop both aerobic and glycolytic running fitness. Meanwhile appropriate mobility and flexibility work will help ensure good mechanics while optimizing performance and reducing recovery time. An additional modest amount of strength training will help keep a strong core for efficient force transmission, while lower body strength will help you develop more efficient strides to run faster.
