The aim of the present study was to compare the aerobic and anaerobic power and capacity of elite male basketball players who played multiple positions. Fifty-five healthy players were divided into the following three different subsamples according to their positional role: guards (n = 22), forwards (n = 19) and centers (n = 14). The following three tests were applied to estimate their aerobic and anaerobic power and capacities: the countermovement jump (CMJ), a multistage shuttle run test and the Running-based Anaerobic Sprint Test (RAST). The obtained data were used to calculate the players' aerobic and anaerobic power and capacities. To determine the possible differences between the subjects considering their different positions on the court, one-way analysis of variance (ANOVA) with the Bonferroni post-hoc test for multiple comparisons was used. The results showed that there was a significant difference between the different groups of players in eleven out of sixteen measured variables. Guards and forwards exhibited greater aerobic and relative values of anaerobic power, allowing shorter recovery times and the ability to repeat high intensity, basketball-specific activities. Centers presented greater values of absolute anaerobic power and capacities, permitting greater force production during discrete tasks. Coaches can use these data to create more individualized strength and conditioning programs for different positional roles.

Acute effects of loaded whole body vibration training on performance.

Asian J Sports Med 2015 Mar 20;6(1):e24054. Epub 2015 Mar 20.

Background: The application of whole body vibration (WBV) as a warm-up scheme has been receiving an increasing interest among practitioners.

Objectives: The aim of this study was to determine the effect of loaded and unloaded WBV on countermovement jump, speed and agility.

Patients And Methods: Twenty-one healthy male college football players (age: 20.14 ± 1.65 years; body height: 179.9 ± 8.34 cm; body mass: 74.4 ± 13.0 kg; % body fat: 9.45 ± 4.8) underwent randomized controlled trials that involved standing in a half squat position (ST), ST with 30% of bodyweight (ST + 30%), whole body vibration at f = 50 Hz, A = 4 mm (WBV), and WBV with 30% bodyweight (WBV + 30% BW) after a standardized warm-up. Post measures of countermovement jump, 15-m sprint, and modified t-test were utilized for analyses.

Results: One way repeated measures ANOVA revealed a significant difference in the countermovement jump performance, F (3, 60 = 9.06, η2 = 2.21, P = 0.000. Post-hoc showed that WBV + 30% BW posted significant difference compared to (P = 0.008), ST + 30% BW (P = 0.000) and WBV (P = 0.000). There was also a significant difference in the sprint times among interventions, F (3, 60) = 23.0, η2 = 0.865, P = 0.000. Post hoc showed that WBV + 30% BW displayed significantly lower time values than ST (P = 0.000), ST + 30% BW (P = 0.000) and WBV (P = 0.000). Lastly, there was a significant difference in the agility performance across experimental conditions at F(2.01, 40.1) = 21.0, η2 = 0.954, P = 0.000. Post hoc demonstrated that WBV have lower times than ST (P = 0.013). Also, WBV + 30% BW posted lower times compared to ST (P = 0.000), ST + 30% (P = 0.000) and WBV (P = 0.003).

Conclusions: Additional external load of 30% bodyweight under WBV posted superior gains in countermovement jump, speed and agility compared to unloaded WBV, loaded non-WBV and unloaded non-WBV interventions.
