Effect of core strength and endurance training on performance in college students: Randomized pilot study

Core training continues to be emphasized with the proposed intent of improving athletic performance. The purpose of this investigation was to discover if core isometric endurance exercises were superior to core isotonic strengthening exercises and if either influenced specific endurance, strength, and performance measures. Ten untrained students were randomly assigned to core isometric endurance (n = 5) and core isotonic strength training (n = 5). Each performed three exercises, two times per week for six weeks. A repeated measures ANOVA was used to compare the measurements for the dependent variables and significance by bonferroni post-hoc testing. The training protocols were compared using a 2 x 3 mixed model ANOVA. Improvement in trunk flexor and extensor endurance (p < 0.05) along with squat and bench press strength (p < 0.05) occurred with the strength group. Improvement in trunk flexor and right lateral endurance (p < 0.05) along with strength in the squat (p < 0.05) were found with the endurance group. Neither training protocol claimed superiority and both were ineffective in improving performance. Published by Elsevier Ltd.
