To determine the impact of a fatigue trial on the scores and number of jumps in a Tuck Jump Assessment (TJA) in female collegiate club athletes. The TJA is a 10-second plyometric jumping assessment used to replicate sport and identify lower extremity landing patterns. Scores from the TJA are summed together and those who score a 6 or higher are suggested for intervention training. Methods: Sixteen female club athletes (age: 20.9+1.9 years, weight: 59.13+7.72kg, height: 64.56+2.63cm) completed the TJA twice, once before performing a Wingate protocol and then again after. A dependent sample t-test was performed to determine any statistical differences between the TJA scores and the number of jumps between pre-Wingate and post-Wingate trials. Results: There was a statistically significant difference between scores for the TJA pre-Wingate (5.8+2.1) and post-Wingate (7.7+1.4) (P<0.0001), with nearly 2 more flaws following the Wingate protocol. There was also a statistically significant difference between the number of jumps for the pre-Wingate (15.1±3.6) and post-Wingate (16.9±2.5) (P = 0.022) with approximately 1 more jump following the Wingate protocol. Conclusions: The Wingate protocol had an impact on both the number of flaws and number of jumps, suggesting that athlete fatigue caused by completion of the Wingate protocol contributed to the increased number of errors in the TJA. The most common flaws were "pause between jumps" and "feet do not land in the same footprint". A statistically significant difference between the number of jumps pre-to post-Wingate TJA was also found. There were a greater number of jumps in the post-Wingate TJA than pre-Wingate. Due to the increased scores in the post-Wingate condition, having athletes complete a fatiguing protocol prior to the TJA may provide a more sport-like level of exhaustion. Recreating similar conditions athletes are sustaining during their sport could give a more accurate representation of the TJA, thereby making it a more clinically relevant and viable tool to use.

“…If a decrease in balance is detected, a training program may be recommended to improve athletes' balance and reduce the risk of injury (Knight et al, 2016). A well-designed resistance training program is a vital component to improve lower-body strength and it is important to apply exhaustive exercises to lower extremities on certain days (Cooper, Dabbs, Davis, & Sauls, 2018). Multiple exercises including dynamic/static, proactive and reactive types of balance should be used during balance training to target each balance dimensionindividually (Kiss, Schedler, & Muehlbauer, 2018)…”

Balance is the process of maintaining the body center of gravity vertically over the base of support and relies on rapid, continuous feedback and integration of afferent information coming from three sensory components, that is somatosensory, visual, and vestibular systems, resulting in smooth and coordinated neuromuscular actions. To investigate the effects of fatigue index on the static balance of sportsmen. A total of 51 male elite sportsmen from 4 different sports branches (Football players: 19, Volleyball players: 13, Skiers: 10 and Athletes: 9) participated in the study. The Wingate anaerobic power and capacity test was applied to induce fatigue. The Technobody isokinetic balance meter (Pro-Kin. CSMI) was used to measure pre- and post-fatigue static balance. There was a significant interaction between dependent (pre and post test balance) and independent (test statue and sport branches) variables were observed (F(63,1031.14) = 1.59, η2 = .07, p ˂ .05). Main effect results showed that pre-fatigue balance values were significantly different than post-fatigue balance values in all groups (F(1.14, 213.91) = 177.99, η2 = .49, p ˂ .05).Moreover, significant differences were identified between pre- and post-fatigue test results in sport branches (F(3.188) = 4.12, ƞ2 = .06, p < .05) and test statue (eyes open and closed) (F(3.188) = 3.32, ƞ2 = .05, p < .05). Bonferonni follow-up test indicated that there was a significant increase from footballers’ average static balance to the athletes’ average static balance (p ˂ .05). In test statue, pre fatigue eyes closed values were significantly different than post fatigue eyes opened values (p ˂ .05). Static balance training should be included in the training to be performed, fatigue static balance training should be performed in team and individual sports and the content of the training should be reorganized in line with the results obtained.

“…Within basketball, standardized and repeatable jumping assessments are amongst the most popular to assess neuromuscular function [8][9][10][11][12]. The ability to produce substantial amounts of force onto the ground to vertically displace the center of mass is an important skill contextually within the game, since basketball athletes execute around 45 jumps per game [3].…”

“…To overcome this issue, repeated jumping and hopping tasks can be used, as they permit evaluating the ability to produce high vertical ground reaction forces in short ground contact times. In fact, the reactive strength index (RSI) (i.e., ratio of JH/contact time) has been previously used to measure both performance and fatigue within athletes [8,22].…”

Basketball is a game of repeated jumps and sprints. The objective of this study was to examine whether repeated jump assessments the day prior to competition (MD-1) could discriminate between fast and slow in-game performances the following day. Seven NCAA Division I Basketball athletes (4 guards and 3 forwards; 20 ± 1.2 years, 1.95 ± 0.09 m, and 94 ± 15 kg) performed a repeated-hop test on a force platform before and after each practice MD-1 to assess Reactive Strength Index (RSI) and Jump Height (JH). Peak speed was recorded during games via spatial tracking cameras. A median split analysis classified performance into FAST and SLOW relative to individual in-game peak speed. Paired T-tests were performed to assess post- to pre-practices differences. An independent sample T-test was used to assess the differences between FAST and SLOW performances. Cohen’s d effect sizes (ES) were calculated to determine the magnitude of the differences. Statistical significance was set for p ≤ 0.05. Post-practice RSI and JH were significantly higher than pre-training values prior to the FAST but not the SLOW in-game performances. A significant difference was found for MD-1 RSI when comparing FAST and SLOW conditions (p = 0.01; ES = 0.62). No significant between-group differences were obtained in JH (p = 0.07; ES = 0.45). These findings could have implications on the facilitation of reactive strength qualities in conjunction with match-play. Practitioners should evaluate the placement of stimuli to potentiate athlete readiness for competition.
