Seventeen soccer players (age 17.9±1.0 years; 178.6±5.0 cm; 73.6±6.6 kg; 11.1±1.3%) from a team competing in a national junior league took part in the study. The athletes performed a series of pre and post training tests (incremental test on a treadmill to determine the maximal oxygen uptake (VO2max), velocity at maximal oxygen uptake (vVO2), the lactate threshold (LT) and T-CAR). The interval training models applied were with 180° direction change (T12:12; n=9) and without direction change (T6:6; n=8). No significant interaction (time vs. group) was observed for the majority of variables analyzed (p > 0.05), although significant main effects in time were evident regarding PVTREAD (F=56.3; P<0.0001), vVO2max (F=35.8; p<0.0001), LT (F=57.7; p<0.0001) and PVT-CAR (F=52.9; p<0.0001). Moreover, there was no significant change in...

To determine test-retest reliability of PVT-CAR, 34 adolescents (U-12, n = 13; U-14, n = 21) performed the Carminatti's test twice within 3-5 days. Validity was assessed in 43 adolescents (U-14, n = 20; U-16, n = 23) submitted to both the Carminatti's test and an incremental treadmill test to determine their aerobic fitness indicators. The intraclass correlation of PVT-CAR was 0.89, 0.93, and 0.81 with a coefficient of variation of 2.30% (0.33 km·h), 1.89% (0.26 km·h), and 2.66% (0.39 km·h) for the total sample (pooled data) or separately for the U-12 and U-14 groups, respectively. No significant difference was found between PVT-CAR and maximal aerobic speed (MAS) for the total sample (pooled data) or separately for the U-14 and U-16 groups. In ad...

O experimento foi realizado em Piracicaba-SP, durante três anos agrícolas, avaliando-se 24 ciclos de produção:12 com poda de inverno e 12 com poda de verão. O delineamento experimental utilizado foi o de blocos casualizados, sendo os tratamentos correspondentes a oito datas de poda: 20/julho, 04/agosto, 19/agosto e 03/setembro (inverno) e 01/fevereiro, 15/fevereiro, 02/março e 16/março (verão). A duração em dias e os valores dos índices IB, IH, IHG e UF foram analisados pelo teste de Tukey ao longo das datas de poda e pelo teste F para constrastes ortogonais para as épocas de poda, ambos a 5% de probabilidade. Os resultados mostraram que a inclusão do elemento meteorológico insolação ou do fator fotoperíodo à base do conceito térmi...

Thirty professional national level team-sport players (n = 12 futsal players and 18 soccer players) volunteered to participate in this study. The subjects performed the TCAR and a laboratory incremental treadmill test (ITT). The TCAR required subjects to complete repeated sets of 5 × 12-second shuttle-running bouts at progressive speed until volitional exhaustion. Each 12-second bout and series were separated by a 6- and 90-second recovery periods, respectively. The initial distance was set at 15 m and was progressively increased by 1 m each set. The ITT commenced at a velocity of 9.0 km·h(-1) and was increased by 1.2 km·h(-1) each 3 minutes until volitional exhaustion. Peak TCAR running velocity resulted not significantly (p &amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;gt; 0.05) different from speed at VO2max (vVO2max) during ITT.

In light of this study results, the TCAR can be considered as a viable field test to estimate aerobic power and capacity in team-sports players. The limited devices and space required by TCAR warrant consideration for those strength and conditioning professionals who deal with team sports.

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…
