Running/Endurance Related Research

Omega-3 Supplements May Reduce Inflammatory Response To Exercise
These findings suggest that omega-3 supplementation decreases soreness, as a marker of inflammation, after eccentric exercise. Based on these findings, omega-3 supplementation (3,000 mg/day) could provide benefits by minimizing post-exercise soreness and thereby facilitate exercise training in individuals ranging from athletes undergoing heavy conditioning to sedentary subjects or patients who are starting exercise programs or medical treatments such as physical therapy or cardiac rehabilitation.  -Journal of Sports Science and Medicine

Effects of Dynamic Stretching on Energy Cost and Running Endurance Performance in Trained Male Runners
 There was no difference in the distance covered after quiet sitting (6.3 ± 1.1 km) compared with that for the stretching condition -Journal of Strength and Conditioning Research

Running Injuries - Changing Trends and Demographics
Running injuries are common. Recently the demographic has changed, in that most runners in road races are older and injuries now include those more common in master runners. In particular, Achilles/calf injuries, iliotibial band injury, meniscus injury, and muscle injuries to the hamstrings and quadriceps represent higher percentages of the overall injury mix in recent epidemiologic studies compared with earlier ones. Evidence suggests that running mileage and previous injury are important predictors of running injury  -Current Sports Medicine Reports

IT Band SyndromeThe strongest evidence for an effective treatment comes from a prospective trial that emphasized correction of weakness in hip abductor strength. In this trial, of the 24 affected runners, 22 resolved symptoms by 3 months and a 23rd by 6 months, using a regimen of lateral leg lifts. (side leg raises)

Patello-Femoral Syndrome:  Treatment of PFS with orthotics now has relatively strong evidence (SOR A). This comes from recent prospective controlled trials, as well as several case series.

Achilles:  The best evidence for effective treatment of Achilles tendinopathy comes from eccentric exercise protocols studied by Alfredson et al. (stand with toes on a step, and slowly body weight using the effected leg). This type of rehabilitation led to the resolution of tendinopathy in most individuals with noninsertional injuries.

Carbohydrate-Protein Intake and Recovery from Endurance Exercise: Is Chocolate Milk the Answer?
...but present evidence suggests that CHO + Pro beverages may positively influence recovery under some exercise conditions, and chocolate milk is likely a good recovery beverage for lactose-tolerant endurance athletes.  Current Sports Medicine Reports

Aging and Factors Related to Running Economy

The results from this cross-sectional analysis suggest that age-related declines in running performance are associated with declines in maximal and submaximal cardiorespiratory variables and declines in strength and power, not because of declines in running economy.  Journal of Strength and Conditioning Research  (evidence that older runners could benefit from strength training!)

MY COMMENTS: Summary-Take fish oil daily, don't bother with dynamic stretching prior to running, drink chocolate milk after workouts, and stay strong!
