French Contrast Training in Male Collegiate Basketball Players

2026年8月18日 更新者：Ziren Zhao

Effects of 12 Weeks of French Contrast Training on Lower-Limb Explosive Performance in Male Collegiate Basketball Players

This randomized controlled trial evaluated the effects of 12 weeks of French Contrast Training (FCT) compared with traditional resistance training (RT) on lower-limb explosive performance in male collegiate basketball players. Forty participants were randomly assigned in a 1:1 ratio to either the FCT group or the RT group. Both groups trained twice per week for 12 weeks, with at least 48 hours between sessions. Lower-limb performance was assessed before and after the intervention using countermovement jump height, drop jump height, ground contact time, reactive strength index, 10-m sprint time, and isometric mid-thigh pull peak force. The study aimed to determine whether FCT produces greater improvements in jumping performance, reactive strength, short-distance acceleration, and maximal force than traditional resistance training.

武器和干预

参与者组/臂
干预/治疗
实验性的：French Contrast Training Group
Participants assigned to this arm completed a 12-week French Contrast Training program, with two training sessions per week and at least 48 hours between sessions. Each training sequence consisted of four exercises performed in order: back squat at 85% of 1RM, 30-cm hurdle jumps, squat jumps at 25% of 1RM, and band-assisted jumps. A 20-second recovery period was provided between consecutive exercises. Participants completed 4 sets of 8 repetitions for each exercise, with 3 minutes of rest between sets. Training loads were prescribed based on baseline 1RM values and remained unchanged throughout the 12-week intervention. All sessions were supervised by certified strength and conditioning coaches.

有源比较器：Resistance Training Group
Participants assigned to this arm completed a 12-week traditional resistance training program, with two training sessions per week and at least 48 hours between sessions. The program consisted of back squat at 85% of 1RM, Romanian deadlift at 85% of 1RM, leg press at 85% of 1RM, and walking lunge at 30% of 1RM. Participants completed 4 sets of 8 repetitions for each exercise, with 3 minutes of rest between sets. Training loads were prescribed based on baseline 1RM values and remained unchanged throughout the 12-week intervention. All sessions were supervised by certified strength and conditioning coaches.

措施说明
大体时间
Countermovement Jump Height
大体时间：Baseline and immediately after the 12-week intervention
Countermovement jump (CMJ) height was assessed using a force platform system (Kistler, Winterthur, Switzerland; sampling frequency: 1000 Hz). Participants performed three maximal countermovement jumps with their hands placed on the iliac crests to minimize arm-swing contribution. A 1-minute rest interval was provided between attempts. The highest jump height, expressed in centimeters (cm), was used for analysis.

次要结果测量

措施说明
大体时间
Drop Jump Height
大体时间：Baseline and immediately after the 12-week intervention
Drop jump (DJ) height was assessed using a force platform system (Kistler, Winterthur, Switzerland; sampling frequency: 1000 Hz). Participants stepped from a 30-cm box onto the force platform and immediately performed a maximal vertical jump while attempting to minimize ground contact time. Three maximal attempts were performed with 1-minute rest intervals. The trial with the highest reactive strength index was selected, and DJ height from the same trial was recorded in centimeters (cm).
Baseline and immediately after the 12-week intervention
Ground Contact Time
大体时间：Baseline and immediately after the 12-week intervention
Ground contact time (GCT) was obtained during the drop jump test using a force platform system (Kistler, Winterthur, Switzerland; sampling frequency: 1000 Hz). The trial with the highest reactive strength index was selected, and GCT from the same trial was recorded in milliseconds (ms).
Baseline and immediately after the 12-week intervention
Reactive Strength Index
大体时间：Baseline and immediately after the 12-week intervention
Reactive strength index (RSI) was assessed during the 30-cm drop jump test using force-platform data. Participants completed three maximal attempts, and the trial producing the highest RSI was used for analysis. RSI was calculated from drop jump performance and ground contact time.
Baseline and immediately after the 12-week intervention
10-Meter Sprint Time
大体时间：Baseline and immediately after the 12-week intervention
Sprint performance was assessed using electronic timing gates (Brower Timing Systems, Draper, UT, USA). Participants started from a split-stance position 0.5 m behind the first timing gate and sprinted maximally through 15 m. Three maximal trials were completed with 2-3 minutes of rest between trials. The fastest 10-m sprint time, expressed in seconds (s), was used for analysis.
Baseline and immediately after the 12-week intervention
Isometric Mid-Thigh Pull Peak Force
大体时间：Baseline and immediately after the 12-week intervention
Isometric mid-thigh pull (IMTP) peak force was assessed using a force platform system (Kistler, Winterthur, Switzerland; sampling frequency: 1000 Hz). Knee and hip angles were standardized at approximately 130° and 145°, respectively. Participants pulled maximally against a fixed bar for 3-5 seconds. Three maximal attempts were completed with 2-minute rest intervals, and the highest absolute peak force value, expressed in Newtons (N), was used for analysis.
