Differentiating physical fitness training for students by applying LGRA analysis

Physical fitness training is just as important as traditional physical education. In terms of the remedial program of physical education, this study offers an important teaching suggestion for people to avoid suffering from obesity. Centering on 1476 freshmen, people with obesity were selected from the unqualified list. Selection criteria were: Male students whose body fat exceeds 25%, with female students whose body fat exceeds 30%. In total, researchers selected 76 students (5.1%) from the unqualified list, 30 male students (39.5%) and 46 female students (60.5%), data was analyzed by adopting the Local Gray Relational Analysis (LGRA). In the case of female freshmen, the results of LGRA between body composition and each fitness sub-test showed that obesity was significantly correlated with muscular endurance and flexibility. Average weight was correlated with muscular endurance and cardiorespiratory endurance, and below average weight was correlated with flexibility and muscular endurance. On the other hand, in the case of male freshmen, the analysis revealed that obesity and average weight were significantly correlated with muscular endurance (LGRA=1 and 1, respectively), and below average weight was significantly correlated with cardiorespiratory endurance, muscular endurance and power (LGRA=1, 0.91734872, and 0.838105731, respectively).The results could mean that different body composition of students have different strengths of fitness components. This combining psychology could specify a feasible strategy on remedial program of fitness.
