Abstract
OBJECTIVE:
Two components of flexibility, muscle tightness, and ligamentous laxity in college athletes were studied to determine whether these factors were associated with the incidence of lower extremity injuries.
DESIGN:
Prospective cohort study.
SETTING:
College athletic department.
PARTICIPANTS:
201 college athletes.
OUTCOME MEASURES:
College men and women athletes were tested for ligamentous laxity with the Beighton scale and for muscle tightness with a new scale based on the tightness of the iliopsoas, iliotibial band, hamstring, rectus femoris, and gastrocsoleus muscles. Lower extremity injuries incurred during practice and play were recorded during the following year.
RESULTS:
Of the 201 athletes tested, 71 sustained 115 injuries. For each additional point on the 9-point ligamentous laxity scale (9 = hyperlax), the risk of injury decreased 16%. For each additional point on the 10-point muscle-tightness scale (10 = all muscles tight), the risk of injury increased 23%. The two scores were moderately inversely correlated (Spearman's rho = -0.3; p < .001). Women had greater mean (+/- SD) laxity scores than men (3.3 +/- 2.2 vs. 1.8 +/- 2.0; p < .001) and lower mean overall muscle tightness scores (1.5 +/- 1.6 vs. 3.5 +/- 2.1; p < .001). Among Women athletes, the rate of lower extremity injury was unrelated to ligamentous laxity or to flexibility. Among men, lower extremity injuries were associated with lower ligamentous laxity scores (p = .008) and greater muscle tightness (p = .04).
CONCLUSIONS:
This study introduces a new scale for lower extremity muscle tightness. Tight ligaments and muscles are related to injury in men, but not women, college athletes. A preseason flexibility program may decrease injuries in college men athletes.

Abstract
DOELWIT:
Twee komponente van buigsaamheid, spier digtheid en ligament laksheid in Kollege atlete is bestudeer om te bepaal of hierdie faktore was. . wat verband hou met die voorkoms van onderste ledemate beserings
DESIGN:
Voornemende cohort studie.
SETTING:
. College atletiek Departement
Deelnemers:
201 Kollege atlete.
uitkomsmaatstawwe:
Kollege Mans en vroue-atlete is getoets vir ligament laksheid met die Beighton skaal en vir spier digtheid met 'n. nuwe skaal gebaseer op die digtheid van die iliopsoas, iliotibiale band, dyspier, rectus femoris, en gastrocsoleus spiere. Onderste ledemaat beserings aangegaan tydens die praktyk en speel gedurende die volgende jaar.
RESULTATE:
Van die 201 atlete getoets, 115 opgedoen 71 beserings. Vir elke bykomende punt op die 9-punt ligament laksheid skaal (9 = hyperlax), die risiko van besering verminder 16%. Vir elke bykomende punt op die 10-punt spiere digtheid skaal (10 = al spiere styf), die risiko van besering verhoog 23%. Die twee tellings is matig omgekeerd gekorreleer (Spearman se rho = -0,3; p <0,001). Vroue moes 'n groter gemiddelde (+/- SD) laksheid tellings as mans (3.3 +/- 2.2 vs. 1.8 +/- 2.0; p <0,001) en laer gemiddelde algehele spier digtheid tellings (1.5 +/- 1.6 vs. 3.5 +. / - 2.1; p <0,001). Onder die vroue-atlete, die tempo van 'n laer uiteinde besering was nie verband hou met ligament laksheid of om buigsaamheid. Onder die mense, is onderste ledemaat beserings wat verband hou met ligament laksheid laer tellings (P = 0,008) en groter spier digtheid (P = 0,04).
Gevolgtrekkings:
Dit stel 'n nuwe studie vir onderste ledemate spier digtheid skaal. Stywe ligamente en spiere wat verband hou met 'n besering in mans, maar nie vroue, kollege atlete. A voorseisoen buigsaamheid program kan beserings in die kollege mans atlete te verminder.
