Regarding reliability in running speed testing ability of the ATTK, the CMCD, and the WMFB protocols, Pearson's r in correlation with average best running times between two tests were 0.
Regarding reliability in agility testing ability of the ATTK, the CMCD and the WMFB protocols, Pearson's r in correlation with average best times between two tests were 0.
Regarding reliability in cardiovascular testing ability of the ATTK, the CMCD and the WMFB protocols, Pearson's r in correlation with average heart rates between two tests were 0.
The 105 attackers - ATTK, the 129 central midfielders and central defenders--CMCD, and the 126 wide midfielders and full backs - WMFB from norms establishment subject group were subject to test under the PoSMAT Protocol Suite to obtain testing values of speed, agility, and quickness in terms of running time, movement time and total time in seconds according to their playing positions and the corresponding frequency distributions were used to establish one standard deviation 5-tier classification system for norms as per format shown in Table 3.
In terms of speed ability, the 50-m running test protocol can discriminate position-specific speed demand statistically in the order of running time: ATTK > CMCD > WMFB, while the PoSMAT Protocol Suite can rank average running times in the same order, but average ATTK running time was not significantly longer than average CMCD running time.
movement ability), the agility T-Test protocol and the PoSMAT Protocol Suite discriminate position-specific agility demand in the order of movement time: ATTK > CMCD > WMFB, but the average ATTK movement time was not significantly longer than the average CMCD movement time.
As to cardiovascular endurance demand of movement ability, both the RAST protocol and the PoSMAT Protocol Suite can discriminate position-specific cardiovascular endurance demand in the order of heart rate ATTK < CMCD < WMFB without statistical significance.
In other words, CMCD and ATTK positions are replaceable or interchangeable from the perspective of speed and agility.
