Former athletes

Area of Science:

  • Sports medicine
  • Biomechanics
  • Exercise physiology

Background:

  • Assessing long-term effects of athletic training on physical function.
  • Investigating the relationship between athletic specialization and lower-limb health.
  • Understanding the impact of aging on athletic performance in former elite athletes.

Purpose of the Study:

  • To evaluate lower-limb explosive strength in former male athletes across different sports.
  • To determine the influence of lifetime athletic activity on vertical jumping ability.
  • To examine the association between osteoarthritis and jumping performance in older athletes.

Main Methods:

  • Vertical jumping height measured using a contact mat.
  • Participants included former runners, soccer players, weightlifters, and shooters (age 45-68).

  • Statistical analyses included age-adjustment, subgroup analysis (osteoarthritis), and multiple linear regression.

    • Main Results:

    • No significant age-adjusted differences in jumping height across sports.
    • Athletes without osteoarthritis jumped higher than those with osteoarthritis (P < 0.01).
    • Sports increasing jumping height also correlated with predisposition to lower-limb osteoarthritis.
    • Age, disability, and pain negatively impacted jumping height.
    • Lifetime power training and recent team training hours positively associated with jumping height.

    Conclusions:

    • Former elite athletes retain significant lower-limb muscle function, even with osteoarthritis.
    • Athletic specialization influences osteoarthritis development, impacting explosive strength.
    • Lifetime training, particularly power training, is crucial for maintaining jumping performance in aging athletes.
