Trainings for a healthy body

There have been many biomechanical studies investigating ITBS, outlined in a number of recent reviews, often creating more questions than answers. Is ITBS a function of lower limb kinematics as well as ITB force transmission? Are changes in the kinematics of the lower limbs the cause of ITBS or are they a compensatory strategy to accommodate and minimize pain? When investigating sagittal plane kinematics, Orchard et al. found no differences between participants’ healthy (asymptomatic) and affected limbs. Prospectively, Noehren et al. and Friede et al. found that individuals who would go on to develop ITBS exhibited greater hip adduction and knee internal rotation during running when compared with matched controls. Foch et al. found that runners with past histories of ITBS had reduced hip adduction when compared to healthy controls . Noehren et al. found that male runners with ITBS ran with significantly greater hip internal rotation and knee adduction angle. These altered kinematics combined with the increased prevalence of ITBS in men (50–81% of those affected) may allude to pain compensation strategies resulting in kinematic changes. This is supported by studies showing that there is a progressive reduction in peak hip adduction angle during prolonged runs, which may be associated with strategies to reduce pain . Overall, these papers suggest that runners may adopt a pattern that places less strain on the ITB once pain is present.

he present analysis includes 9551 tests (8821 treadmill, 730 cycle ergometer) from 13 participating laboratories (see Acknowledgments) that were performed from January 1, 1980, to January 1, 2021. Geographical representation was limited to the United States. Inclusion criteria used to create the present cohort were as follows: 1) men and women age 20 to 89 yr, 2) no known preexisting diagnosis of cardiovascular disease (coronary artery disease, myocardial infarction, heart failure, peripheral arterial disease, or stroke), 3) no known preexisting diagnosis of chronic obstructive pulmonary disease, 4) not taking β-blocker medications, 5) maximal CPX performed on a treadmill or cycle ergometer, 6) peak respiratory exchange ratio (RER) of ≥1.1 as an objective indicator of performing a maximal effort, and 7) RPE assessed using the Borg scale (6–20) (11).

ata collection and management procedures for the FRIEND registry have been previously reported (12). Briefly, the FRIEND registry is composed of data from high-quality laboratories performing CPX administered by experienced personnel. Although laboratories varied in terms of equipment, protocols, and definitions of CRF (e.g., determined from time averages between 15 and 60 s), all laboratories conducted testing in accordance with published guidelines (22). Each contributing laboratory obtained local research ethics board approval before submitting deidentified, coded data to the data coordinating center and core laboratory at Ball State University, which has institutional review board approval for maintaining the database. Data from each contributing laboratory were reviewed to ensure that values were within expected normal ranges before the data were added to FRIEND.
