  1. Data are presented as numbers with percentages
  2. LBP low back pain, TS throwing arm side, NTS non-throwing arm side
  3. *Statistically significant difference between players without LBP and those with LBP (P <.05). Iliopsoas tightness was evaluated during medical check-ups held in 2017 and 2019 but not in 2018.
