What is Effects of Age and Starting Age Upon Side Asymmetry in the Arms of Veteran Tennis Players: a Cross-sectional Study about?

While tennis playing results in large bone strength benefits in the racquet arm of young players, the effects of tennis playing in old players have not been investigated. Large side asymmetries in bone strength were found in veteran players, which were more pronounced in men, younger players and childhood starters. ## Introduction: Regular tennis results in large racquet arm bone and muscle strength advantages; however, these effects have not been studied in old players. the non-racquet arm can act as an internal control for the exercising racquet arm without confounding factors, e.g. genotype. therefore, veteran tennis player side asymmetries were examined to investigate age, sex and starting age effects on bone exercise benefits. ## Methods: Peripheral quantitative computed tomography (pqct) scans were taken at the radius, ulna and humerus mid-shaft and distal radius in both arms of 88 tennis players (51 males, 37 females; mean age 63.8 ± 11.8 years). thirty-two players began playing in adulthood, thereby termed 'old starters'; players were otherwise termed 'young starters'. ## Results: Muscle size and bone strength were greater in the racquet arm; notably, distal radius bone min
