Abstract The aim of the study was to investigate the differences in bilateral and unilateral dynamic strength index (DSI) between age categories (seniors and juniors), player positions (guards and forwards), its variation during the basketball season, and its association with sprint and change of direction (CoD) performance. Highly trained basketball players ( n = 32) performed bilateral and unilateral countermovement jumps (CMJ), bilateral and unilateral isometric squats, 10-m sprint, and 505 CoD test. DSI was calculated from CMJ and isometric peak force, while 10-m sprint and 505 test were used to calculate the CoD deficit. Two-way factorial analysis showed larger isometric peak force in seniors, and larger bilateral DSI in juniors, while guards had higher DSI values and larger peak force in both metrics compared to forwards. Two-way mixed model ANOVA showed a significant increase in unilateral isometric squat and CMJ peak force force ( g = –0.08 to –0.64) and increase in bilateral DSI values. Post-hoc analysis showed that isometric squat force significantly increased only in seniors ( g = 0.88), resulting in decreased bilateral DSI values ( g = 0.52), with bilateral and unilateral DSI values increasing in juniors. Similar trends were observed in guards and forwards, with guards exhibiting a more pronounced increase in all variables compared to forwards. Furthermore, correlation analysis for in-season testing showed moderate associations between isometric squat peak force and CoD ability ( r = –0.43 to –0.54; P < 0.001), and weak associations between DSI and CoD ability ( r = 0.36 to 0.39; P < 0.05), while associations were not significant for sprint performance. The relationships were lower or absent during pre-season testing. Further interventional studies are needed to determine the usefulness of DSI to guide training related decision-making.

Abstract Purpose Thoroughbred racing jockeys compete at maximum physiological capacity in a sport with a high risk of falls and injury. A greater understanding of the physical capacities determining jockey performance may lead to minimum physical performance parameters and corrective interventions to improve jockey fitness and performance and reduce jockey and horse injury. The aim of this study was to develop appropriate physical testing procedures for jockeys and a physical fitness profile for different licence levels. Methods Fifty-eight jockeys ( n = 24 females, n = 34 males), representing all apprentice jockeys licenced in New Zealand in 2021 (100%, n = 8 probationers and n = 39 apprentices) and eleven professional jockeys (14%) were assessed to determine baseline physiological and fitness data. Descriptive statistics and boxplots were used to compare aerobic fitness, abdominal (core), upper and lower body strength, muscular power, reaction time, flexibility and a novel ‘saddle’ test targeting lower body strength, balance, and endurance between licencing levels. Effect Size (ES) was used to determine magnitude of differences between groups. Results More experienced jockeys had greater relative lower body strength (ES = 0.2–0.7) and better balance (ES = 0.5–0.9) compared to the less experienced groups. Jockeys who were in the top 20 of the premiership table (jockey rankings) had faster reaction times (ES = 0.7) and greater core extensor strength (ES = 0.7) than other cohorts. Most tests showed little differentiation between jockey licence levels, however the ‘saddle test’ showed greater variability in the less experienced race riders. This test may be an effective measure of jockey baseline performance. Conclusions These data could be used to inform minimum jockey licencing requirements and future physical fitness training programmes to increase jockey physiological fitness, thereby minimising risk of falls or injury due to physiological deficits and performance.

Abstract This study aims to evaluate the effect of a 12-week physical training program on police officers’ physical fitness attributes. Thirty male police officers (age, 31.03 ± 3.15 years) participated in this experimental study, having carried out a 12-week physical training program (01−04/2023), 3 times/week with an average duration of 1 h/session (through circuit work, body weight exercises, and exercises with additional weight). The physical fitness evaluations were performed at three time points (weeks: 0, T0; 8, T1; 12, T2), and consisted of morphological (height, weight, waist circumference, fat and muscle mass, body mass index, and waist-to-height ratio) and fitness (push-ups; sit-ups; pull-ups; handgrip; horizontal jump; shuttle-run test; t -test; sit-reach test) evaluations. Were observed significant improvements at (i) 8 week (T1), in waist circumference, waist-to-height ratio, and all fitness tests (except in flexibility, handgrip right/left sum, and VO 2max ); and (ii) 12 weeks (T2), in relative fat mass, relative muscle mass, waist circumference, waist-to-height ratio, and all the fitness tests. Although 8 weeks of training allowed us to observe improvements in most of the physical fitness attributes, all of them improved significantly in the 12-week physical training program. In accordance, prolonging the duration of the training program from, 8 to 12 weeks, results in strong improvement in the physical fitness of police officers.
