Abstract
BACKGROUND: Owing to its combination of speed, tactics, and accuracy, table tennis is becoming a sport exercise that is suitable for older adults. Casual play is fun and relaxing, and more serious table tennis might further develop skills through focused practice. METHODS: A randomized controlled trial (RCT) aimed to determine how the practice of competition compared to leisure playing affects the Quality of life (QoL) of people aged 40-70. Selecting subjects at random, one group of subjects undertook a structured competitive regimen, whereas the other group was given time to play recreationally without any structured competition. QoL was measured before and after the intervention using the WHOQOL-BREF, which measures physical, psychological, social, and environmental domains. Data were analyzed using paired and independent t-test. RESULTS: The group that received structured competition reported a marked improvement in their QoL indicators, especially in physical health (p < 0.001), psychological health (p < 0.001), and social relationships (p = 0.001), when compared to the control group, which showed few improvements. No significant differences were observed in the environmental domains in either group. CONCLUSIONS: Regular competitive table tennis practice improves physical condition, emotions, and social relationships, which leads to a higher QoL in older adults. Thus, these results emphasize the utility of competitive sports in the maintenance of active and healthy aging.
