Girls from around the borough received free basketball coaching from Hounslow Hawks head coach Stefan McGarrell and some of his players.
The coaching, which took place at Lampton Sports Centre, Hounslow, was part of a series of sports camps organised by Fusion, the council's new leisure arm.
It was made possible by funding from the London Summer of Sport initiative.
McGarrell said: "It's fantastic and refreshing to see young girls taking an interest in basketball, both playing and coaching, and getting involved with other girls from across the borough."
Fusion's Dan Reynolds added: "These sessions have been focused on providing quality coaching sessions for girls, as research has shown that the number of girls in their teens taking part in sport is significantly lower than boys of the same age.
"We hope that these girls will continue taking part in sport by joining their local club."
All those who attended the camps will have the opportunity to join Hawks' new junior section, which trains at Heston Sports Hall each Friday from 3-5.30pm.
