The association between flexibility and running economy in sub-elite male distance runners.

The purpose of this study was to examine the association between nine measures of limb and trunk flexibility and running economy. Within a week prior to running economy assessment, and after 10 min of jogging at 3.13 m.s-1, 19 well-trained male sub-elite distance runners underwent two complete sets of lower limb and trunk flexibility assessments. Runners then completed two 10-min running economy assessment sessions on consecutive days at 4.13 m.s-1 following two 30-min sessions of treadmill accommodation at 4.13 m.s-1. Intraclass correlation coefficients indicated that the repeated flexibility measurements were highly reliable (X R = 0.92 +/- 0.09), as were the two running economy appraisals (R = 0.99). Correlational analyses revealed that dorsiflexion (r = 0.65) and standing hip rotation (r = 0.53) were significantly (P < or = 0.05) associated with the mean aerobic demand of running, such that runners who were less flexible on these measures were more economical. Although speculative, these results suggest that inflexibility in certain areas of the musculoskeletal system may enhance running economy in sub-elite male runners by increasing storage and return of elastic energy and minimizing the need for muscle-stabilizing activity.

Clearing athletes for participation in sports. The North Carolina Medical Society Sports Medicine Committee's recommended examination.

The North Carolina Medical Society's Medicine Committee has reviewed current U.S. literature on preparticipation examinations and adopted a documentation form that fits the specific needs of our state. In spite of a recently published comprehensive monograph on preparticipation physical evaluation, no national consensus exists about whether comprehensive preparticipation exams or brief, focused examinations are better. With this in mind, we limited medical history questions to those determined by previous studies to identify specific problems. Also included are evaluations of blood pressure, musculoskeletal, and cardiovascular systems since studies have shown significant yield from these. The same studies find little benefit from the remainder of a comprehensive physical assessment. The recommended evaluation represents a minimal standard and addresses the core areas likely to prevent athletes from participating safely in sports. No recommended exam could cover all issues that affect school-age athletes--health prevention, adolescent development, general medical care, and psychological stresses--but physicians can use the recording form as a starting point and incorporate a more extensive evaluation into the assessment of athletes found to be at increased risk. Consistent use of this examination should promote better detection of sport-specific risks related to cardiovascular disorders, asthma, musculoskeletal problems, concussions, heat-related problems, and general medical problems. The Sports Medicine Committee wants to promote physical activity. Before disqualifying athletes physicians should remember that the disqualification rate in published studies averages only 1%. When questions about the need for disqualification arise, consultation may be advisable.(ABSTRACT TRUNCATED AT 250 WORDS)

Rehabilitation exercises for common sports injuries.

Residual weakness after joint injury is a risk factor for recurrent injury. A rehabilitation program helps patients recover strength and helps prevent further injuries. Orthopedic injuries account for 10 percent of visits to family physicians, yet many primary care physicians do not routinely prescribe rehabilitation exercises for injured patients. Illustrations of exercises for the hip, knee, ankle and shoulder are included as a reference for family physicians to use when prescribing rehabilitation exercises.

Focusing the preparticipation sports examination.

Athletic preparticipation evaluations are among the most common routine health screening tools, yet no standardized approach to these evaluations has been adopted. This paper presents a focused preparticipation examination form developed by the authors with the assistance of the North Carolina Academy of Family Physicians' Task Force on Sports Medicine. After reviewing the major studies of preparticipation examinations, 11 basic questions that identify specific risks for sports participation were selected. Three specific components form the core of the physical examination: blood pressure measurement, a comprehensive orthopedic examination, and cardiovascular auscultation. Other portions of the physical examination may be included because of sport-specific risks or problems identified in the history, but are not routine. The rationale for this form and guidelines for the physician to make recommendations for sports participation and timing of reevaluation are discussed.

A prospective study of type A behavior and running injuries.

A prospective study was developed to examine whether personality factors predispose runners to injury. Forty runners who completed a type A behavior screening were followed for 1 year during which they documented their training mileage, injuries, and time lost from training because of injury. Runners with high scores on the type A behavior screening questionnaire experienced significantly more injuries, especially multiple injuries. Although not significant, high scorers lost nearly twice as much training time because of injury. No significant relationship was found between mileage and injury. The data suggest that a type A behavior score warrants consideration as a predictive risk factor when screening for potential running injuries.

Myocardial infarction and denial.

Denial, a natural defense mechanism, can be either an appropriate or an inappropriate response to anginal pain. Myocardial infarction sufferers often delay several hours before seeking medical attention, and most deaths from infarction occur before hospitalization. These two facts indicate that denial may contribute to mortality from coronary artery disease. To encourage "stoical" patients to seek medical care, nonthreatening educational approaches to cardiac disease and concentrated efforts to reduce anxiety toward hospitals are needed. Family physicians knowledgeable about the effects of denial can screen cardiac-prone patients for inappropriate denial and alter diagnostic approaches in an attempt to lessen the role denial plays in cardiac deaths.

Leiomyosarcoma of the femoral vein in a marathon runner.

Leiomyosarcoma of the femoral vein is a rare tumor. Physicians involved in the care of athletic patients must not be cavalier in evaluating overuse injuries and should endeavor to make a specific diagnosis. If atypical findings, such as generalized extremity swelling, are present, the physician must consider systemic illness including malignancy in apparently healthy, physically active individuals.
