When running backward downhill, the ball of the foot is used whereas forward downhill running uses mainly the heel to absorb the force. This requires more coordination and therefore develops brain

or alternative mixed running. Some believe that running backwards helps balance out the strain brought on by normal running. Reversing the direction works the friction of tissues oppositely. Running flat or uphill, the heel is used to push off rather than the ball of the foot as normally occurs with

Backward running adds another dimension to running, and when complemented by sidestepping in both directions (with and without crossovers front and behind intermittently) covers the essential dimensions of human movement on the two-dimensional plane. Diagonal movement as well as curving running (as

Running backwards down a hill is more dangerous, and it is advised that someone learn how to drop into a backward roll before attempting it, to deal with any resulting tripping or loss of balance in the prone movement. Although the distance to the ground is greater running downhill backwards, the

Other advantages to backward running are a reduction in fear related to the movement, a form of exercise that is naturally more reserved, gains in balance, and the general enjoyment resulting from entertaining activities like these. Due to constantly having to look behind oneself, or sometimes

Running backwards up a hill is not very dangerous. It will always be at a lower speed due to the enhanced difficulty, and if one trips there is less of a distance towards the ground and it is easier to absorb the impact with the arms and buttocks so that the head is not as likely to hit.
198:
As the head faces forward, running backwards has the danger in that the runner cannot see anything on the ground or in the way of his or her path. Unlike forward running, it is also much more difficult to brace a backward fall or drop into a roll if one trips.

While downhill backward running is essentially the reverse of uphill running, and uphill backward running of downhill running, they are different in that the fibres would fire differently due to differences in the isotonic motions. The former is an

Backward running is a less-natural motion but can be accomplished with some speed with practice. It is better to start out backward walking (also called retropedaling), which is relatively easy, and increase speed over time. Like normal running,

keeping the eyes fixed, people can learn to run with more neck mobility or without a straight look ahead. This can stress the neck muscles which can be dangerous if done too aggressively, but in the long term could lead to adaptations in them.

incline makes it much easier to perform rolls in downhill running, than when running level ground, so it can be done more instinctively. This applies to backward running and the backroll as it does to front running and the front roll.

BR had reduced PFJCF compared to FR. This was caused by an increased knee moment, due to differences in magnitude and location of the GRF vector relative to the knee. BR can therefore be used to exercise with decreased

movement, and the latter is a concentric version of an eccentric movement. Both concentric and eccentric movements have advantages in training, which is why most weight lifters perform both for set times.

Patellofemoral pain (PFP) is a common injury and increased patellofemoral joint compression forces (PFJCF) may aggravate symptoms. Backward running (BR) has been suggested for exercise with reduced PFJCF.

backward running had significantly higher magnitude of coordination variability compared to forward running, signifying that more degrees of freedom were involved in backward running

With all forms there is an obvious backward lean relative to normal running's forward lean, which can shift the stress of the other muscle fibres a small degree.
