Validity and reliability of a new field test (Carminatti's test) for soccer players compared with laboratory-based measures

Abstract

The aim of this study was to assess the validity (Study 1) and reliability (Study 2) of a novel intermittent running test (Carminatti's test) for physiological assessment of soccer players. In Study 1, 28 players performed Carminatti's test, a repeated sprint ability test, and an intermittent treadmill test. In Study 2, 24 players performed Carminatti's test twice within 72 h to determine test-retest reliability. Carminatti's test required the participants to complete repeated bouts of 5 × 12 s shuttle running at progressively faster speeds until volitional exhaustion. The 12 s bouts were separated by 6 s recovery periods, making each stage 90 s in duration. The initial running distance was set at 15 m and was increased by 1 m at each stage (90 s). The repeated sprint ability test required the participants to perform 7 × 34.2 m maximal effort sprints separated by 25 s recovery. During the intermittent treadmill test, the initial velocity of 9.0 km · h(-1) was increased by 1.2 km · h(-1) every 3 min until volitional exhaustion. No significant difference (P > 0.05) was observed between Carminatti's test peak running velocity and speed at VO(2max) (v-VO(2max)). Peak running velocity in Carminatti's test was strongly correlated with v-VO(2max) (r = 0.74, P < 0.01), and highly associated with velocity at the onset of blood lactate accumulation (r = 0.63, P < 0.01). Mean sprint time was strongly associated with peak running velocity in Carminatti's test (r = -0.71, P < 0.01). The intraclass correlation was 0.94 with a coefficient of variation of 1.4%. In conclusion, Carminatti's test appears to be avalid and reliable measure of physical fitness and of the ability to perform intermittent high-intensity exercise in soccer players.

Determination of Aerobic Performance in Youth Soccer Players: Effect of Direct And Indirect Methods

“…The velocity associated with VO 2max (Va max ) was the lowest exercise intensity at which VO 2max was obtained. If the intensity of VO 2max was not sustained for at least 1 min, the intensity at the previous stage was recorded as Va max (Silva et al, 2011).…”

“…Reports concerning correlations between the results of the SRT and TCar tests and the results of laboratory tests, as well as the variables measured in the two types of tests (field and laboratory) are scarce and controversial (Aziz et al, 2005; Denadai et al, 2002; Silva et al, 2011; St Clair Gibson et al, 1998). Thus, we performed the present study to correlate and compare the results of variables measured in indirect and field tests (SRT and TCar) with the results of the same variables evaluated in laboratory tests in a group of youth soccer players.…”

Physiological Responses During the Time Limit at 100% of the Peak Velocity in the Carminatti’s Test in Futsal Players

“…Each stage consisted of 5 repetitions with a 6 s walking period between 2 lines set 2.5 m from the starting line. From eight to ten athletes were evaluated simultaneously with the running pace dictated by a pre- recorded audio system (Da Silva et al, 2011). The test ended when participants failed to follow the audio cues on the front line for 2 successive repetitions (objective criteria determined by observers).…”

“…Thus, the use of the peak velocity (PV) from intermittent field tests with varied distances and direction change has been an interesting alternative to evaluate aerobic power in team sports (Dittrich et al, 2011) and it has been used for the prescription of interval training (Da Silva et al, 2015). Besides its applicability, practicality, low financial cost and high ecological validity (Svensson and Drust, 2005), PV is also associated with maximum aerobic speed (MAS) and repeated sprint ability (Da Silva et al, 2011). …”

The Yo-Yo Intermittent Tests: A Systematic Review and Structured Compendium of Test Results

“…The majority of field tests are performed as exhaustive running tests measuring total distance covered, maximal test duration or maximal speed as easy-to-access outcome parameters. While continuous running tests (Balke, 1963; Léger and Boucher, 1980; Ramsbottom et al, 1987) such as the Cooper test (Cooper, 1968) are typically performed on 200 or 400 m tracks, multi-stage shuttle-run tests consist of repeated short distance runs (Léger and Lambert, 1982; Krustrup et al, 2003; Da Silva et al, 2011). In this regard, shuttle-run tests also include an agility component immanent to sports that involve intermittent exercise such as soccer or basketball (Bangsbo et al, 2008).…”
