INTRODUCTION
Attack tempo is the elapsed time between the setting touch and the
attack hit (Fernández, Salas, & Molina, 2009).

INTRODUCTION
Attack tempo is one of the main variables in the game because it’s a
determinant factor for the block cohesiveness and the attack
efficacy (Afonso & Mesquita, 2011).

INTRODUCTION
Data Volley System (Data Project, Bologna, Italy, release 3.4.2)
includes attack tempo in its category system.

INTRODUCTION
The different user manuals of this software are unclear with the
criteria to distinguish quick, fast, and high attacks.

INTRODUCTION
Fernández et al. (2009) propose three criteria to define the attack
tempo categories:
1) Control the trajectory (maximum height) of the setting pass. 2) Observe the relationship between set and attack. 3) Examine the interaction between attack and block.

INTRODUCTION
The purpose of the present study was to analyse the relationship
between attack tempo and type of block in high-level men’s
volleyball.
Thus, we expected to determine:
1) The time intervals when the different types of block are
significantly formed.
2) A temporal threshold to differentiate fast and high attacks of the
outside hitters.

METHODS
Participants
• 15 volleyball matches (57 sets) from the 2010 Men’s Pan-
American Cup held in San Juan (Puerto Rico).
• 9 national teams: Argentina, Brazil, Canada, Colombia,
Dominican Republic, Mexico, Puerto Rico, USA, and Venezuela.
• 1451 multi-events (attack-block interactions).
10
METHODS
Observational instrument
1) Attack tempo = 21 categories: 0.2 to 2.2 s.
2) Type of block = 5 categories (Data Volley System):
No block Single Hole Double Triple
11
METHODS
Procedures and material
The matches were recorded using a digital camcorder (JVC Everio
GZ-MG630) at 25 FPS.
12
METHODS
Procedures and material
Frame-by-frame analysis was performed using Kinovea video analysis
software (Charmant & Contrib., Bordeaux, France, release 0.8.15).
13
METHODS
Procedures and material
Multi-events were recorded using MS Excel 2007 and were analysed
using SDIS-GSEQ statistical software (Bakeman & Quera, Atlanta, GA,
EUA, release 5.1).
14
METHODS
Statistical analysis
• The relationship between attack
tempo and type of block criteria was
assessed using Pearson’s chi-square
tests for independence. Statistical
significance was set at P < 0.05.
• The adjusted residual for each cell
of the contingency table was
computed. A z-score greater than 1.96
indicated that the relationship between
a given and a target category was
significant.
15
RESULTS
• There was a relationship between attack tempo and type of block
criteria (2 = 718.50, P < 0.01).
• Twenty-two significant relationships were found between the given
and the target categories (Z > 1.96, P < 0.05):
No block Single Hole Double Triple
0.4, 0.8 – 0.9 s 0.2 – 0.9 s 1.0 – 1.2 s 1.3 – 1.8 s 1.6 – 1.8 s

DISCUSSION
Non-cohesive blocks + jump settings in ideal zones
+ attack simulations by the middle hitters
(Afonso, Mesquita, Marcelino, & Da Silva, 2010)
No block Single Hole Double Triple
Cohesive blocks + settings in non-
ideal zones + non-simulations by the
middle hitters (Afonso et al., 2010)
Quick attacks of the middle hitters: 0.3 – 0.5 s
(Selinger & Ackermann-Blount, 1992)
Fast attacks of the outside hitters: 0.6 – 1.2 s
(Selinger & Ackermann-Blount, 1992; Zimmermanm, 1993)
High attacks of the outside hitters: 1.3 s onwards
(Zimmermanm, 1993)
