Here we look at the 8 key causes of plantar fasciitis, so you can take steps to reduce your risk of injury during sporting endeavor, and your day-to-day life.
1. Certain types of exercise.
Activities such as long-distance running, ballet dancing and certain kinds of aerobics and high intesity interval triaing can contribute to an earlier onset of plantar fasciitis. This is due to the pressure these exercises apply to the heel and surrounding tissue. Taking up running without existing conditioning for this activity, may also result in plantar fasciitis.
Being flat-footed, having a high arch or even having an abnormal pattern of walking can adversely affect the way weight is distributed when you're standing and put added stress on the plantar fascia. Furthermore, those with pronation of the foot are at increased risk. Pronation is the term for the mechanism of walking with an inward rotation or twist of the foot.
3. Existing Muscle tension.
Those suffering from existing tightness in the Achilles tendons and/or calf muscles are at heightened risk of suffering from planar fasciitis. If you experience muscle tightness, it is important to incorporate dynamic stretching into your daily routine, utilize heat therapy or consult a sports physiotherapist for a professional massage to these areas.
4. Excess Body-weight.
Excess body weight increases stress levels to the body, as movement impact is heightened and overall stability and balance is compromised. In order to reduce your susceptibility to injury, it is strongly recommended to maintain your weight to a healthy standard. For those with a high level of excess body-weight, low-impact exercises such as swimming are an excellent way to partake in cardiovascular exercise and burn fat, whilst exerting minimal impact stress to the muscles and joints.
5. Inappropriate Footwear.
Wearing shoes with poor cushioning or structural support can increase risk of injury. Furthermore, women who transition from wearing high heels for extended periods of time to flat sports shoes, may also experience heel and foot pain or injury.
Plantar fasciitis is most common between the ages of 40 and 70. Foot pain is, unfortunately, an affliction that is common among the middle-aged and elderly. Ensuring you wear correct supportive foot wear, and maintain mobility of the foot muscles - by performing simple stretches and staying active - will help protect you against the risk of injury.
7. Extended Periods of Standing.
Those in occupations that require long periods of standing on hard surfaces are at a heightened risk of experiencing damage to their plantar fascia muscle. This risk may be minimized by wearing correct, supportive footwear, and varying the levels of movement throughout the day (e.g periods of strolling at various speeds, and some seated rest periods.)
8. Training on Hard Terrain.
Training on hard surfaces such as concrete, non-built-for-purpose exercise studios and non-sprung wood floors heighten the risk of plantar fasciitis. Over an extended period of time, the heightened impact of such surfaces is a significant stressor to the joints and supporting muscles, which may result in injury.
As such, athletes in extended training are recommended to use built-for-purpose training facilities where possible. Built-for-purpose facilities - such as tennis and basketball courts, gymnasiums and dance studios - have sprung floors which minimize the stress impact on the body.
Tellingly, plantar fasciitis is also sometimes referred to as 'joggers heel'. Runners are recommended to vary their terrain to help negate the damaging impact of running on hard surfaces such as concrete. Varying a running training routine with cross-country terrain, where possible, is highly favorable in order to reduce the risk of injury.
