Outline • Video Show & Case Introduction • Epidemiology of Running Injuries • Risk Factors for Adolescent Runners • Preventive Measures • Effectiveness • Q & A
Epidemiology of Running Injuries • Incidence rate10: • 37-56% of runners • 2.5-12.1 injuries/1000hrs • No significant association between age & injury40 • Koplan et al, 1982 • Blair et al, 1987 • Jacobs & Berson, 1986 • Macera et al, 1989 • Walter et al, 1989
Overuse Injuries • Repetitive loading23 • foot strike 1,000-1,500 times per mile • 2-3 times of body weight • 20-70% among all injuries40
Risk Factors contributing to overuse injuries In Children and Adolescent
Intrinsic Factors 1. Growth • Repetitive microtrauma damage growth cartilage at 3 sites24 Growth plate Articular cartilage Apophyseal insertion Adopted from Micheli (1983)
Intrinsic Factors • Injuries at : • Growth plate • Salter type I injury3, 14 • Articular cartilage • Osteocholdritis dissecans3, 24 • Apophyseal insertion • Traction apophysitis3, 14 Salter type I injury Adopted from Apley (1993)
Intrinsic Factors 2. Growth process • Growth of bones > growth of muscles14, 24 • tightness and inflexibility • stress at joint surface14, 24
Intrinsic Factors 3. Anatomical malalignment • Femoral neck anteversion Predispose patellofemoral symptoms14, 19
Intrinsic Factors • Anatomical malalignment • Q-angle (in female) • Predispose to chondromalacia patellae14 • Coxa vara and valgus deformity of knee • Predispose to traction apophysitis14 Adopted from Magee (1997)
Intrinsic Factors 4. Menstrual dysfunction in young female • Intense training may lead to secondary amenorrhea1 • estrogen secretion and bone mass1 • risk of stress #1
Intrinsic Factors 5. Psychological factors • Exaggerate personality such as tension28 • Excressive expectation from adult • return to play too soon • denial of symptoms of injury28, 38
Extrinsic Factors 1. Training error • Sudden change of training intensity10, 40 • Hill running37 • Excessive training demand by coaches and parents10
Extrinsic Factors 2. Inappropriate equipment / footwear12 • Improper fit of the shoes • Lack of ability to correct malalignment • Decreased ability for shock absorption
Extrinsic Factors 3. Running surface • Hard or uneven surface40 • Slant running surface10 • Change in running surface40
Training Advice • Preparticiaption screening (esp. growth risk factors, psychological factors)13, 14 • Early sport specialization avoided1 • Attention to adolescent growth spurt14, 24
Training Advice • Conditioning and flexibility • General fitness14 • Stretching (for bone growth factors)13
Training Advice • Nutrition intake (e.g. Fe, Ca)1 • Monitor body composition, weight, stature, cardiovascular findings, sexual maturation, emotional stress1 • Risk of heat injury1, 27 • Careful monitoring of amenorrhea2 • 10% rule for intensity increment25
Training Advice • Psychological Health for adolescents • Prevent unrealistic expectation from parents and coaches14 • Enjoyment rather than competition • Respect child’s autonomy
Equipment Advice • Shoes • Regular replacement of running shoes • Slip, curve last; soft sole; narrow flare for pes cavus feet 23 • Straight, board last; rigid medial insole; wide flare for pes planus feet23
Equipment Advice • Brace • External ankle support devices • Knee brace • Taping
Rules and Regulation • Age limit (Rules from HKAAA) • 5000m and 10000m Age 16 or above • 3000m SC Age 14 or above • Age limit for local athlete events • Watson’s Water HK Age Group Athletic Meet 2002 • 5000m Age 17 or above • Watson’s Water Athletic King Championships 2002 • Age 20 or below for Junior Group
Rules and Regulation • Age limits for local Long Distance Running competition • Nike Youth Road Relay 15km---Age 14 • King of the Road 10km---Age 17 • Mizuno half-marathon 21.0975km---Age 16 • Nike 10km---Age 16
Effectiveness of preventive measure • Yeung and Yeung, 2001b • Verhangen et al. (2000) • Quinn et al. (2000) • Cook et al. (1990)
Meta-analysis46 Yeung and Yeung, 2001b • Effectiveness of stretching exercise is unknown • Application of shock absorbing insole is not effective
Critical Review41 Verhangen et al. (2000) • Braces seem to be more effective in preventing ankle sprains than tape • The use of either tape or brace also results in less severe ankle sprains
Meta-analysis34 Quinn et al. (2000) • Use of external ankle support devices, e.g. a formal semi-rigid ankle orthoses or Aircast brace to prevent ligamentous injuries
Critical Review12 Cook et al. (1990) • All running shoes lose between 30-50% of their shock absorbency characteristics after as little as 400km of running
Conclusion • Early specialized training ( esp. distance running ) are not recommended • Various preventive measures can reduce the chance of getting injuries
