Running is a popular form of exercise that offers numerous physical and mental health benefits. While most individuals are familiar with the concept of uphill running and its challenges, downhill running often receives less attention. Downhill running involves running on a decline, leveraging gravity to propel oneself forward. So what can downhill running improve?
Enhanced Lower Body Strength:
Downhill running engages different muscle groups compared to flat or uphill running. The eccentric muscle contractions during downhill running place greater emphasis on the quadriceps, hamstrings, calves, and glutes. These muscles act as shock absorbers, controlling the descent and stabilising the body against the impact of each stride. Regular downhill running can strengthen these muscles, leading to improved overall lower body strength.
A study published in the Journal of Strength and Conditioning Research found that downhill running significantly increased eccentric knee extensor strength and muscle fibre cross-sectional area compared to level running.
Improved Running Economy:
Running economy refers to the energy cost of maintaining a given running speed. Efficient running economy allows runners to cover longer distances with less energy expenditure. Downhill running, due to its eccentric nature, has been shown to positively influence running economy.
Research published in the European Journal of Applied Physiology revealed that downhill running at a moderate grade improved running economy and efficiency. The eccentric muscle contractions during downhill running aid in the development of neuromuscular coordination and enhance muscle-tendon elasticity. These adaptations contribute to a more efficient running stride, resulting in improved overall running economy.
Speed Development:
Downhill running can be a valuable component in speed development training. The gravitational assistance provided during downhill running allows runners to achieve higher speeds than they would under normal conditions. This speed adaptation can carry over to flat and uphill running, enabling athletes to perform at a faster pace.
A study published in the Journal of Strength and Conditioning Research demonstrated that downhill running training improved 5-km race performance. The participants who incorporated downhill running into their training regimen displayed enhanced running speed and stride length, leading to faster race times.
Rehabilitation and Injury Prevention:
While downhill running is associated with high impact forces, when performed correctly and progressively, it can play a role in injury prevention and rehabilitation. Downhill running places less stress on the joints compared to uphill or level running due to the eccentric nature of muscle contractions.
Research published in the Scandinavian Journal of Medicine & Science in Sports suggested that downhill running can be an effective rehabilitation method for patellar tendinopathy (also known as jumper's knee). The study found that eccentric downhill running reduced pain and improved function in individuals with patellar tendinopathy.
Downhill running, often overlooked compared to uphill or level running, offers several benefits supported by scientific research. It can enhance lower body strength, improve running economy, contribute to speed development, and be used as a rehabilitation tool. However, it is important to approach downhill running with caution, gradually increasing intensity to avoid excessive strain on the muscles and joints. Incorporating downhill running into training programs or workout routines can help individuals maximise their running potential and overall fitness levels.
