 The purpose of this study was to investigate the applicability of the exercise and sports life stage (ESLstage) scale. The participants were 20,000 Japanese (9,956 men, 10,044 women, 18-79 years old) who responded to the “public opinion survey for sports participation” published by the Japan Sports Agency (2019b). The scale items related to each element of “do”, “watch” and “support” in ESL (exercise and sports life) were selected from the questionnaire (Japan Sports Agency, 2019b) by fish-bone diagram analysis. Categorical factor analysis (independent cluster rotation) with a 4-factor model based on the results of parallel analysis showed that the ESL structure was made up of “ES (exercise and sports) orientation”, “health and physical fitness”, “motivation to watch ES” and “richness of daily life”. In addition, categorical factor analysis with a unifactor model confirmed sufficient unidimensionality, and the latent rank theory (LRT) was applied. The number of the latent rank (LR) was examined using goodness-of-fit indices, information criteria, and segmented regression analysis (SRA). As a result, an ESL-stage scale with a 6-rank model was constructed. The Spearman’s rank correlation coefficients for the LRs of ESL-stage between “ES participation frequency” and “ES-related money costs” were ρ = .55 and .51 (both p <.01), respectively. These results suggested that the criteria-related validity of the ESL-stage scale was sufficient. The ESL-stage LRs with an “ES participate frequency” of more than 1 and 3 days/week were LR4 “enriching everyday life through ES” and LR6 “performing social activities through ES”, respectively. An ESLstage profile chart was created to encourage understanding of the stages and processes characteristic of the ESLstage. In addition, an environment was established for objectively discriminating the ESL-stage LRs using a concurrent calibration method. Since the ESL-stage scale was standardized using LRT, cross-sectional comparison and longitudinal comparison of ESL-stage are possible. It is expected that use of the ESL-stage scale will enrich individual ESL and contribute to the realization of a life-long sports society and extension of healthy life expectancy.
