Novel curvilinear sprint test in basketball: reliability and comparison with linear sprint. J Strength Cond Res 37(9): e535-e540, 2023-This study (a) evaluated the reliability of a curvilinear sprint (CS) test to assess kinetic and kinematic outcomes in basketball players, (b) compared the kinetic and kinematic outcomes derived from curvilinear vs. linear sprints (LS), and (c) examined the association of both the CS and LS with change of direction (COD) performance. Thirty young basketball players (17 men and 13 women) competing at the national level (i.e., Spanish Basketball National League) performed a novel CS test around the 3-point line (the 3-point line CS test) to the right and left sides. The maximum and average values of acceleration (ACC), velocity (VEL), and centripetal force (CentF) were measured using Local Positioning System technology (WIMU PRO, Realtrack Systems S.L., Almería, Spain). All outcomes showed a high relative (intraclass correlations coefficient $ 0.90) and absolute (coefficient of variation [CV] , 5%) reliability, except the maximal CentF to the right (CV 5 5.41%) and left sides (CV 5 7.72%). Linear sprints displayed higher ACC and VEL outputs compared with the 3-point line CS test (all p , 0.001). Both sprinting tests were very large to nearly perfect associated with COD performance (LS r range from 20.71 to 20.86; CS r range from 20.68 to 20.94; p , 0.001), and the curvilinear ACC max was the kinematic outcome most strongly associated with COD performance (r range from 20.73 to 20.94). In conclusion, the 3-point line CS test is reliable to measure CS performance in basketball and presents different kinetic and kinematic features than LS.

Novel Curvilinear Sprint Test in Basketball: Reliability and Comparison With Linear Sprint

“…Game speed and the number of high‐intensity activities such as sprinting, changing of direction (COD) and jumping performed during match‐play has significantly increased in the last decade in sports like soccer (Barnes, Archer, Hogg, Bush, & Bradley, 2014), basketball (García, Vázquez‐Guerrero, Castellano, Casals, & Schelling, 2020) or tennis (Fernandez‐Fernandez, Sanz, & Mendez‐Villanueva, 2009). While attacking and defending, athletes are required to continually accelerate, decelerate and make quick changes in speed and direction in very short periods of time (Salaj & Markovic, 2011).…”

This study aimed to assess the association of the mechanical variables derived from the force-velocity (FV) profile (i.e. theoretical maximal force [F 0 ], velocity [V 0 ] and maximal power output [P max ]) with change of direction (COD) performance in soccer, basketball and tennis players. Fifty-four male athletes (soccer n = 23; tennis n = 16; basketball n = 15) were assessed for the vertical (Vrt) and horizontal (Hzt) FV profiles, COD with the dominant (D) and nondominant (ND) legs, using the modified 505 test, and sprint. Hzt FV profile parameters showed stronger associations with performance than Vrt FV profile in the three sports. Specifically, the Hzt parameter most strongly associated with COD performance was F 0 in tennis (r =-0.83; p<0.001) and P max in soccer and basketball (r =-0.79; p<0.001). Associations between sprint times and COD test ranged from (r = 0.73 to 0.82) in soccer players, (r = 0.74 to 0.87) in tennis players and (r = 0.62 to 0.85) in basketball players, respectively (p<0.05). Considering the whole sample and the random effect of the type of sports, an improvement in sprint acceleration (i.e. one N/kg increase in F 0 and one W/kg in P max) was associated with-0.15 s and-0.04 s to complete the 505 test, respectively. In conclusion, our results suggest the potential usefulness of assessing the Hzt FV profile to maximize acceleration capabilities through training interventions which, in turn, may translate into improved COD performance. However, further longitudinal and experimental research is needed to confirm this hypothesis.

“…The intermittent nature of basketball is predominantly characterized by high-intensity accelerations ($2 m•s 22 ), decelerations (#2 m•s 22 ), and short sprints at high speed (.18 km•h 21 ) (7). Throughout a game, basketball players are required to perform repeated highintensity changes of direction (CODs) and sprints, both with and without the ball, during offensive and defensive actions, regardless of the playing position (3,31).…”

Baena-Raya, A, Jim énez-Reyes, P, Romea, ES, Soriano-Maldonado, A, and Rodríguez-P érez, MA. Gender-specific association of the sprint mechanical properties with change of direction performance in basketball. J Strength Cond Res 36(10): 2868-2874, 2022-We evaluated the gender-specific associations between the mechanical variables derived from the horizontal force-velocity (FV) profile (i.e., theoretical maximal force [F 0 ], velocity [V 0 ], maximal power output [Pmax], peak ratio of the effective horizontal component [RF peak ], and the force application technique index [D RF ]) and the change of direction (COD) performance for basketball players. Seventy-one players (23 women and 48 men) were assessed for the horizontal FV profile and COD using the modified 505 and V-cut tests. The FV profile parameters were significantly higher for the men than those for the women. The F 0 , RF peak , and Pmax were strongly associated with performance in the 505 test (women r range 5 20.72 to 20.82; men: r range 5 20.67 to 20.75; p , 0.001) and the V-cut test (women r range 5 20.68 to 20.76; men r range 5 20.45 to 20.50; p , 0.001), as well as with a lower COD deficit (women r range 5 0.58 to 0.75 (p , 0.01); men r range 5 0.49 to 0.54; all p , 0.001). For the women, a 1 N•kg 21 increase of the F 0 was associated with 20.20 seconds and 20.56 seconds in the 505 and V-cut tests, respectively, and 0.16 seconds for the COD deficit. In the men, it was associated with 20.13 seconds and 20.37 seconds in the 505 and V-cut tests, respectively, and 0.10 seconds for the COD deficit. F 0 , RF peak , and Pmax are the most determinant sprint mechanical properties to successfully COD and reduce the COD deficit. The horizontal FV profile assessment is recommended for diagnosing and prescribing a training program for basketball players.
