Background: Weight training and its relationship to improving vertical jump has been extensively researched to determine its importance in improving vertical jump height (VJH). A meta-analysis has shown a positive relationship between implementing weight training and plyometric training and improving VJH (Perez-Gomez & Calbet, 2013). Objectives: This study aimed to assess the effects of a strength training intervention on vertical jump performance in the University of Chichester Men’s basketball team. The second aim of this study was to examine whether plyometric principles can be trained within a normal basketball training sessions and if this is sufficient to improve vertical jump performance. It will also be investigated whether the number of basketball sessions attended correlated with improvement of VJH. Methods: Participants consisted of 11 members of the University of Chichester Men’s basketball team (age 20.6 ± 1.63 year), five of which were assigned to the experimental group (year 21 ± 1.87 age) and completed the weight training interventions twice per week as well as regular basketball practices sessions twice per week. The remaining six participants where part of the control group (year 20.3 ± 1.51 age) which only completed regular basketball sessions twice per week and occasional games once per week. The 11 participants completed initial testing in countermovement jump (CMJ), countermovement jump without arm swing (CMJWA) and depth jump (DJ) from 30cm at the start and end of the six-week intervention. Results: Pre- versus post testing was analysed for intervention and non-intervention groups. There was no significant difference between pre and post CMJ in the experimental group (t4= -0.491, d = 0.219, p 0.649). There was no significant difference between pre and post CMJ test in the control group (t5= -0.87, d = -0.355, p 0.424). There was no significant difference between pre and post CMJ without arm swing in the experimental group (t4= -0.722, d = -0.323, p 0.51). There was no significant difference between pre and post CMJ without arm swing test in the control group (t5= -0.827, d = 0.338, p 0.446). There was a significant difference between pre, and post depth jump height in the experimental group (t4= -5.791, d = -2.59, p 0.004). There was no significant difference between pre, and post depth jump height test in the control group (t5= 0.178, d = 0.073, p 0.866). There was a significant strong positive correlation between CMJ (rp = 0.726, p = 0.011), CMJWA (rp = 0.658, p = 0.028), and DJ ground contact time (rp = 0.763, p = 0.006), with attendance of basketball sessions. There was a non-significant weak negative correlation between DJ VJH performance with attending basketball interventions (rp = 0.269, p = 0.423). The experimental group made significant improvements from pre to post in barbell back squat one rep max(1RM) (t4= -4.355, d = -1.947, p 0.012), Romanian deadlift 1RM (t4= -3.773, d = -1.687, p 0.02), quarter squat 1RM (t4= -3.897, d = 1.743, p 0.018) and calf raises maximal repetitions max with two 40 kg dumbbells (t4= -3.855, d = 1.724, p 0.018). Conclusion: The current study indicates that strength training twice per week and basketball training twice per week for a six-week period does not significantly increase VJH in CMJ, CMJWA, DJ in members of the University of Chichester Men’s basketball team. Although lower body strength significantly improved as a result of the intervention it did not impact VJH performance. However, a correlation between the number of basketball sessions attended and VJH performance in CMJ and CMJWA was evident suggesting this may be sufficient in increasing VJH.
