Effect of different number of players and training regimes on physiological and technical demands of ball-drills in basketball. Issue 8 (17th April 2016) - Conte, Daniele
Abstract: This study aimed to analyse the effects of two factors (number of players and training regimes) on players' physiological and technical demands in basketball ball-drills. Twenty-one young basketball players performed four different ball-drills (two levels for each factor). The number of players involved was 2vs2 and 4vs4, while ball-drill regimes were continuous and intermittent. Physiological demand was assessed using the percentage of maximal heart rate (%HRmax ), Edwards' training load and rating of perceived exertion (RPE). Furthermore, the following technical actions were collected: dribbles, steals, rebounds, turnovers, passes (total, correct, wrong and % of correct pass) and shots (total, scored, missed and % of made shot). A 2 × 2 (number of players × regime) two-way ANOVA with repeated measures was applied for physiological parameters and technical actions. The 2vs2 condition showed higher %HRmax ( P < 0.001), Edwards' training load ( P < 0.001), RPE ( P < 0.001), number of dribbles ( P < 0.001), rebounds ( P < 0.001), passes [total ( P = 0.005) and correct ( P = 0.005)] and shots [total ( P < 0.001) scored ( P < 0.001) and missed ( P < 0.001)] than 4vs4. Moreover, the continuous regime revealed higher %HRmax ( P < 0.001), Edwards' training load ( P < 0.001), RPE ( P = 0.006) and dribbles ( P < 0.001) than the intermittent regime. This study showed that both number of players and regime are useful variables able to modify basketball ball-drills workload.
