This study aims to select adequate questionnaire items to evaluate the leadership abilities of a soccer coach, who can lead his team to victory. On the basis of the “coach’s qualifications and task” offered by the Japan Football Association in addition to previous studies, it is assumed that the coaches’ leadership abilities are composed of the following six factors: “human nature,” “general nature,” “analysis and evaluation of a game,” “team management,” “coaching policy,” and “coaching skill.” After examining the content validity, 227 questionnaire items were selected. The survey was conducted with 183 soccer players who had over three years of soccer experience (valid responses: 162). They answered either “right,” “not right,” or “I do not know” for each item. After the items were analyzed on the basis of the three predetermined criteria’s, 113 items were judged to be adequate. The reliability of the questionnaire was high (α = 0.95). It was considered that items cover the above “coach’s qualifications and task.” Furthermore, to enhance the utility of the questionnaire, it will be necessary to carefully choose questionnaire items in the future.

Curcumin, from turmeric, has been investigated for its anti-inflammatory activity. We investigated the effects of giving the curcumin on delayed onset muscle soreness and muscle function following eccentric exercise. We used a randomized, double-blinded, placebo-controlled, crossover trial with two 8-day testing phases and a 3-month washout period. Ten healthy male subjects performed two bouts of eccentric exercise involving elbow flexion (6 sets of 4 repetitions) 30 min after curcumin (150 mg) or placebo was given. Perceived muscle soreness, maximal voluntary isometric elbow flexor strength, elbow range of motion (ROM), and upper arm circumference were assessed before, immediately post (0), 24, 48, 72, and 96 h following exercise. All parameters changed significantly (p<0.05) in both groups at 0 h. There was significantly (p<0.05) less perceived muscle soreness and higher maximal isometric strength in the curcumin group compared with the placebo group after 48, 72, and 96 h. There was a significant (p<0.05) smaller reduction in elbow ROM in the curcumin group compared with the placebo group at 0, 24, 48, 72, and 96 h. No differences were observed in upper arm circumference. This suggests that curcumin can alleviate muscle soreness and enhance muscle recovery after exercise-induced muscle damage.
