Are Young Female Basketball Players Adequately Prepared for a Force–Velocity Jumping and Sprinting Assessment?

Jessica Rial-Vázquez, Iván Nine, María Rúa-Alonso, Juan Fariñas, Roberto Fernández-Seoane, Pedro Jiménez-Reyes, Miguel Fernández-del-Olmo, and Eliseo Iglesias-Soler

Purpose: The aim of this study was to explore the interday reliability of mechanical variables obtained from the horizontal and vertical force–velocity (FV) profiles in adolescent female basketball players. If found to be reliable, the associations between FV parameters (theoretical maximal force, velocity, and power), squat jump (SJ) height, 30-m sprint, and change of direction (COD) times were evaluated. Methods: After familiarization, SJ against incremental loads, 30-m sprint, and 505-COD tests were obtained twice in 36 adolescent female basketball players (age = 15.4 [1.2] y). Results: Reliability for vertical FV parameters was unacceptable, whereas 505-COD times and FV horizontal parameters (except for theoretical maximal power) showed a moderate to high reliability. 505-COD time was correlated with FV horizontal parameters (range: r = −.821, −.451), and a large association was observed with both SJ height (r = −.678, −.600) and 30-m sprint time (r = .813, .858). Conclusions: Due to low levels of strength, our athletes were not adequately prepared to obtain a reliable vertical FV profile. Practitioners can expect acceptable reliability of the horizontal FV profile. Given the association between COD performance and SJ height and 30-m sprint time, we encouraged practitioners with limited equipment at their disposal to use COD and/or 30-m sprint tests.

Effects of Brief Mindfulness Training on Basketball Free-Throw Shooting Performance Under Pressure: A Randomized Controlled Trial of Dosage Response

Jessyca N. Arthur-Cameselle and Linda A. Keeler

Studies have indicated that as little as 15 min of mindfulness training (MT) positively affects sport performance under pressure, but the minimum amount of MT required to induce effects is unclear. The current experiment tested the effects of MT of different lengths on free-throw shooting under pressure. Forty-six participants (78% men) with competitive basketball experience completed pretest mindfulness and anxiety surveys and shot under low pressure. Using performance-based matched assignment, participants were randomly distributed into groups. On another day, participants completed audio trainings (6-min MT, 15-min MT, or control) and then shot under high pressure. Under high pressure, anxiety and mindfulness states did not differ among groups, nor were there group differences in average shooting percentage. However, only the control group performed worse on the second shot under high pressure compared with low pressure, suggesting possible protection effects of MT. Findings are discussed regarding application and possible interactions between traits, motivation, and incentive values.
