Storm Basketball Foundation ran a free basketball club at Millais School, in Horsham, after school on Fridays with the aim of increasing activity levels among girls.
Bex Ashdown, head of PE at the all girls school, said 55 different young girls had attended the sessions since September.
She said: “I think within the school it has built up a real enthusiasm for basketball. We have got kids coming who do not come to any other clubs.
“It started with five or six to start with and now we can have up to 45 at a time. Some of them have gone on to extra activities outside of school hours.”
The club attracted a wide mix of girls.
12-year-old Pranavi Prasath moved to the UK from India last year and who used to play basketball back at home.
She said: “I really love coming here. I love basketball and it is really fun. It is fun because it is competitive and it is about teamwork.”
Janeria Quansah, 13, said: “I have learnt a lot, it is really fun. When I am doing it I feel like I am making good use of my time. If I was not doing this I would be at home sleeping.”
A number of the girls revealed basketball was not offered in their primary schools so they were pleased when they realised they could play it at secondary school.
Rachel Roberts, 12, said: I like basketball, but at primary school there was no basketball so when I found out I could do it here I wanted to.
“Basically I taught myself by watching a few videos and practising at home. Last year I got a basketball hoop so I now play with my dad.
“I used to enjoy football but I did not really like watching it on TV because they all just cry for no reason, but with basketball they are more about the game. I prefer basketball as it is more competitive.”
Weronika Domanska, 12, agreed, adding: “I do it because it is competitive. It is quite challenging but once you play it it is really fun.
“It is good for me and it is an extra skill for life. It teaches you a lot, such as competition.”
For 13-year-old Kyla Hodgson it is the social aspect that she enjoys.
“I have always liked basketball and it is an opportunity to meet new people. I have made a couple of new friends in different year groups and it’s a social hangout. It is one of my favourite sports.”
Karl Youngman, coach at Storm Basketball Foundation, said it has been fascinating watching the girls improve during the last couple of terms.
One barrier he has had to face is teaching the girls they can be more aggressive when it comes to playing basketball.
“When we started it was like netball, but now they have grown in confidence and are a bit more assertive.
“It is the first barrier to breakthrough. Teaching them to get in their opponents face, stop them, play all the defence positions, use speed, and that everybody can shoot and defend.”
The Storm Basketball Foundation is a community programme focused on getting more children playing basketball at a younger age.
Its team of experienced coaches provides school sessions, camps, leagues and competitions to 5-18-year-olds in Crawley, Horsham and the surrounding areas.
The foundation is the base of their programme, providing a pathway into the community club and then into its national league programme.
