Effect of force training on flexibility

Abstract

The purpose of this study is to establish the possible variation between the gain rate in muscular strength and fl exibility due to force training. The research was carried out with a sample of 31 men, users of Rio Sport Center, within age bracket of 20 to 30 years. Inclusion factors were: having been working out at least three months; being users of Rio Sport Center. The measuring made was: 1RM test for bending and supine and hip and knee goniometry, using the CARCI plastic goniometer. Descriptive Statistics techniques were funda- mentally used in relation to statistical treatment.The results found, according to basic statistical data of description of mean values of the va- riables age, height, body mass, cutaneous fold and perimeter, presented a homogenous behavior, indicating normal distributions. Thus, we could treat the sample as a whole and not in a subdivided form. In synthesis, there was homogeneity in the population observed. The results of the mean values of the independent variables, dynamic force of bending and supine, presented a value corresponding to 35.70% and 43.08%, respectively, of the world record (Leighton, 1987), what characterized the assessed group as having a good strength level. The results found, according to basic statistical data of description of mean values of dependent variables, assessed joints fl exibility, presented a maximum value, higher in all assessed movements, than those presented by the literature (American Academy of Orthopaedic Surgeons, 1965; American Medical Association, 1990 and Kapandji, 1990), what demonstrated a group with good fl exibility.The results led to the conclusion that, for the studied group, with their respective characteristics, there is no correlation between dynamic force and fl exibility.
