This study aims to evaluate the effects of different basketball training programs on adolescents with obesity. The objective is to assess how these programs influence body weight, physical fitness, motivation to exercise, and basketball skills.
Three types of programs are being compared:
Participants are adolescents aged 15 to 17 years with moderate obesity who will engage in one of the programs for seven weeks, with one training session per week.
Body weight, physical fitness, motivation, and basketball skills will be measured before and after the intervention to determine which approach is most effective.
The study aims to identify engaging and effective methods for promoting physical activity, health, and basketball skill development in adolescents with obesity.
This randomized controlled trial (RCT) includes three parallel intervention arms designed to evaluate the effects of different basketball teaching programs on adolescents with obesity. The intervention spans seven consecutive weeks and consists of one structured basketball session per week, each lasting 60 minutes and delivered during regular physical education (PE) classes.
A total of 55 adolescents (33 females and 22 males), aged 15 to 17 years and classified as having moderate obesity (BMI: 30-34.9 kg/m²), were recruited from a secondary school in the Sidi Bouzid region of Tunisia. Participants were randomly assigned using a computer-generated sequence to one of the following groups:
Pre- (T0) and post-intervention (T1) assessments included: (i) anthropometric measurements (BMI), (ii) physical fitness tests, (iii) evaluations of technical basketball performance (passing, dribbling, shooting), and (iv) assessments of motivation. Motivation was assessed following the first and final sessions.
Each session was structured into three phases: a standardized warm-up (15 minutes), a main instructional phase (40 minutes), and a cool-down period (5 minutes). The adapted program was tailored to the specific needs of adolescents with obesity by modifying drills, reducing competitiveness, and incorporating extended recovery and instructional periods. Pre-session videos in the ADAPT+VID group were uploaded to a private Facebook group 48 hours prior to each session and engagement was monitored.
The study received approval from the appropriate institutional ethics committee and was conducted in accordance with the Declaration of Helsinki. Written informed consent was obtained from all participants and their legal guardians prior to enrollment.

| Change in Body Mass Index (BMI) in kg/m² | Body Mass Index (BMI) will be calculated using the formula: weight (kg) / height (m²). Weight will be measured using a calibrated digital scale and height using a wall-mounted stadiometer. BMI will be assessed at baseline and after 7 weeks to evaluate the effects of the basketball training intervention on body composition in adolescents with moderate obesity. | From baseline (pre-intervention) to after 7 weeks of intervention |

| Change in Cardiorespiratory Fitness Assessed by Intermittent Fitness Test 15-15. -Unit of Measure: Meters (total distance covered)(Spartacus Test). -Unit of Measure: Meters (total distance covered) | Cardiorespiratory fitness will be assessed using the 15-15 intermittent fitness test (Spartacus Test), a shuttle run test designed for overweight and obese adolescents. The test involves 15-second running intervals alternated with 15-second passive recovery over a 40-meter distance, with progressive speed increases starting at 5 km/h and increasing by 0.5 km/h per stage. The test concludes when the participant fails to maintain pace for two consecutive intervals or stops due to fatigue. The total distance covered will be used to estimate cardiorespiratory fitness (VOâ‚‚peak). The Spartacus test is validated for this population and demonstrates high test-retest reliability (ICC > 0.90). |
| Measure | Description | Time Frame |

| Change in Passing Accuracy in Basketball. -Unit of Measure: Points (maximum possible score based on protocol) | Passing accuracy was evaluated using the AAHPERD Passing Test, which requires participants to perform chest passes at six wall targets within 30 seconds. Points are awarded based on precision and rule compliance. The total score is the sum of two scored trials, after one practice attempt. This test has demonstrated strong reliability (r = 0.84-0.97). |

Three-arm parallel-group randomized controlled trial. Participants were randomly assigned to one of three intervention arms: (i) an adapted basketball program with pre-session video summaries (ADAPT+VID), (ii) an adapted basketball program without video supplementation (ADAPT), or (iii) a traditional basketball program without specific pedagogical modifications (CONT).

| Change in Situational Motivation (SIMS) Scores. - Unit of Measure: Units on the Situational Motivation Scale (SIMS), a 7-point Likert scale with minimum score 1 and maximum score 7. | Motivation was assessed using the Situational Motivation Scale (SIMS), a validated 16-item questionnaire evaluating four subdimensions: intrinsic motivation, identified regulation, external regulation, and amotivation. Each item is rated on a 7-point Likert scale (1 = "does not correspond at all" to 7 = "corresponds exactly"). The average score for each subscale was calculated by averaging the corresponding four items (e.g., intrinsic motivation: items 1, 5, 9, 13). Higher scores indicate greater intensity of the respective motivation type. | Baseline (Session 1) and post-intervention (Session 7, 7 weeks after baseline) |
| From baseline to after 7 weeks of intervention |
| Change in Shooting Accuracy in Basketball -Unit of Measure: Points (0 to 50 maximum) | Shooting accuracy was assessed using a standardized 10-shot free-throw test from the 4.57-meter line, using FIBA-approved size 6 basketballs. Each shot was scored using a 6-level scale (0-5 points), considering precision and shot quality. Total score was calculated by summing the scores of the 10 attempts. | Baseline and after 7 weeks |
| Change in Dribbling Performance in Basketball. -Unit of Measure: Seconds | Dribbling proficiency was evaluated using a timed zigzag cone course (5 cones, 2 meters apart). Participants completed a round-trip dribbling trial; the best of two attempts was retained. Performance was measured in seconds using a stopwatch accurate to 0.01 seconds. | Baseline and after 7 weeks |
