Peak Age and Performance Trajectories in Para Powerlifters

Age-Related Trajectory and Age at Peak Competitive Performance in Wheelchair Rugby Players at the Paralympic Games

OBJECTIVE

The first objective is to examine the age-related trajectory of competitive performance and the age at peak competitive performance in wheelchair rugby players at the Paralympic Games. Another objective is to verify age correlations with performance over the years for each class.

DESIGN

This is a retrospective cohort study.

RESULTS

Data were collected from the official results books of the Paralympic games. The mean age (SD) of the 267 players and 448 analyzed data from all Paralympic games (from Sidney 2004 to Tokyo 2020) across all classes was 32.8 (6.4) yrs, and the age at peak competitive performance was 30.6 (7.4) yrs. Each class had no statistical difference in age at peak competitive performance. In addition, there was no significant correlation between age and performance within classes or across all Paralympic games.

CONCLUSIONS

The findings indicate that wheelchair rugby players' age at peak competitive performance is 30.6 yrs, which remains consistent across all classes. There is no statistical correlation between age and performance in wheelchair rugby. These findings significantly affect effective talent identification and athlete development programs. This impact ensures that athletes receive the necessary support to reach their maximum potential while avoiding the pitfalls of underestimating or overestimating their stages of development.

Paralympic Versus Olympic Canoe Sprint: Comprehension of the Development Trajectory of the Kayak 200 Meters

Improvements in race times for male and female Para canoe athletes across different sports classes have led to a reduction in relative differences between classes over time. However, there is a lack of research examining the comparative developmental trajectories between high-performance Paralympic (PCS) and Olympic (OCS) canoe sprint. In this study, we compared the developmental trajectories of 200-meter kayak performances among PCS and OCS athletes. In total, we analyzed 628 race results obtained from public online databases, for nine competitions between 2015 and 2023. Race times were reduced over the years except in specific sports classes (KL3-M, K1-M, and K1-F; KL: Kayak Level, M: male, F: female), with a poor positive correlation (r = 0.17 to 0.33) between time and the years. For the remaining sports classes, these correlations ranged from poor to fair (r = -0.58 to -0.13). OCS K1 athletes outperformed their Paralympic counterparts. Among Paralympic classes, KL1 had slower times than KL2 and KL3 (p ≤ .05), with KL2 times significantly lower than KL3 in the female category. OCS athletes exhibited less variability in race times compared to PCS athletes. In the male category, there were no significant differences in the coefficients of variation (CV) and amplitude of race times between sport classes, except for KL1-M, which had a larger CV than K1 (p ≤ .05). In the female category, the CV and amplitude of race times were significantly higher in KL1-F compared to KL3-F and K1-F. OCS times remained stable from 2015, with KL3-M following a similar trend. PCS displayed greater race time variability, particularly in higher impairment classes, notably KL1. This underscores the existence of distinct developmental stages within the canoe sprint modality, particularly emphasizing the early developmental phase of KL1. It also provides valuable insights for coaches and sports selection, especially concerning athletes with more severe impairments, including those in Rehabilitation Centers and during athlete recruitment.

Performance Trajectory Related to Age, Classification, and Sex in Elite Kayak Para Canoe Athletes

OBJECTIVE

The aim of the study is to verify the performance trajectory related to age, classification (KL: kayak level; M: male; F: female), and sex of elite kayak Para canoe athletes.

DESIGN

This is a retrospective cohort study.

RESULTS

Race results and athletes' data were retrieved from publicly available online databases for 17 competitions and 102 finals between 2015 and 2022. Race time reduced over the years except for KL3-M class. There was a reduction in the relative difference between KL2-M and KL3-M over the years ( r = -0.83, 95% confidence interval = -0.34 to -0.97, P ≤ 0.05). In addition, no significant differences were found in race times relative differences between KL2-F and KL3-F over the years. Although the correlation between age and performance was only found to be statistically significant in the KL3-F class, the ages of all classes (35.2, 32.6, 29.5, 34.6, 37.6, and 30.6 yrs for males and females KL1, KL2, and KL3, respectively) were higher than those in Olympic canoeing (27.8 yrs).

CONCLUSIONS

Race times have improved overall since 2015, but not for the KL3-M class. Nevertheless, because of the stochastic ages of the finalist athletes, it was not possible to determine the age at which peak performance is achieved in all classes. Kayak Para canoe classes should be monitored in the coming years to determine whether interventions are necessary to improve differentiation.

Para Powerlifting Performance: A Retrospective Analysis Considering Origin of Impairment, Sport Classification, and Sex

OBJECTIVE

We analyzed the retrospective performance of para powerlifters over 8 yrs considering sex, the origin of impairment, and sport classification of para powerlifting.

DESIGN

This retrospective study analyzed data from 6791 (4613 and 2178 for male and female, respectively) individual results from 1634 athletes' performances. We collected absolute load (in kilograms), relative load (in kilogram/body mass), chronological age and origin of impairment (acquired or congenital), and sport classification (leg length difference, limb deficiency, range of movement, impaired muscle power, hypertonia, ataxia, athetosis, and short stature of para powerlifters.

RESULTS

Males were stronger than females thorough the years with acquired impairment being stronger than congenital impairment. Para powerlifters with acquired impairment were older compared with congenital impairment over the years. Acquired impairment males won 60% more medals than the congenital group. There was a significant association between competition achievement and sports class classification, with a higher number of medals for limb deficiency than other sports classes.

CONCLUSIONS

These results demonstrate that the sex, origin of impairment, and sports classification influence performance of athletes in para powerlifting. Thus, this information can help athletes, coaches, sport managers, and sport institutions involved in the sport of para powerlifting.

How Do Intracompetition Strategies Differ Between Para Powerlifting Podium and Nonpodium Athletes? A Retrospective, Cross-Sectional Analysis

ABSTRACT

Beaumont, P, Garrett, J, and van den Hoek, D. How do intracompetition strategies differ between para powerlifting podium and nonpodium athletes? A retrospective, cross-sectional analysis. J Strength Cond Res 38(3): 584-591, 2024-This study aimed to investigate the intracompetition strategies used by para powerlifters and quantify and report them for application by coaches and athletes to improve their odds of competitive success. A cross-sectional retrospective analysis was conducted using a public powerlifting database. Primary analysis categorized athletes as either podium (POD) or nonpodium (NPOD), and a subanalysis classified athletes as either gold medalists (GMs) or silver and bronze medalists (SBMs). Analyses of variance were used to assess the significance of the difference between groups. Pearson's correlations were used to evaluate the magnitude of the relationships and binary logistic regressions were used to quantify the variables. Results are reported as odds ratios, and an alpha level of p < 0.05 was considered statistically significant. There was a significant difference in mean age (POD = 1.6 years younger; p < 0.001), body mass (POD = 2.7 kg heavier; p = 0.006), and best lift (POD = 19.5 kg greater; p < 0.001) for female POD athletes compared with NPOD athletes. For male POD athletes compared with NPOD athletes, there was a difference in mean age (POD = 0.6 years younger; p = 0.035) and best lift (POD = 28.4 kg greater; p < 0.001). Comparing GMs with SBMs showed a significant difference in the mean best lift in both men (GM = 17.4 kg greater; p < 0.001) and women (GM = 11.1 kg greater; p < 0.001). A positive relationship was seen in both the primary and subanalysis between the number of successful lifts (of 3) and an increase in the odds of competitive success (i.e., winning). The findings of this research indicate that high-performing para powerlifters tend to choose attempt weights that prioritize the successful completion of all 3 intracompetition lifts to win a competition.

A Bibliometrics-Enhanced, PAGER-Compliant Scoping Review of the Literature on Paralympic Powerlifting: Insights for Practices and Future Research

Paralympic powerlifting (PP), formerly known as "International Paralympic Committee" (IPC) powerlifting, is the format of powerlifting adapted for athletes with disabilities, and it differs from the version for able-bodied athletes in that it consists of bench press only. According to the mandate of the IPC, PP athletes should be enabled to achieve sporting excellence. As such, rigorous evidence is needed. However, to the best of our knowledge, there exists no systematic assessment of the body of scholarly evidence in the field of PP. Therefore, the present study was conducted to fill in this gap of knowledge, by conducting a scoping review of the literature enhanced by a bibliometrics analysis and by mining two major scholarly databases (MEDLINE via PubMed and Scopus). The aim was to provide a review/summary of the findings to date to help practitioners and athletes. Thirty-seven studies were retained in the present study. These covered the following thematic areas: (i) warm-up strategies (n = 2); (ii) aspects of training (n = 2); (iii) physiological aspects and responses (n = 2); (iv) psychological aspects and responses (n = 2); (v) biomechanics of bench press (n = 8); (vi) recovery strategy (n = 5); (vii) impact of the disability and type of disability (n = 4); (viii) epidemiology of PP (n = 6); and (ix) new analytical/statistical approaches for kinematics assessments, internal load monitoring, and predictions of mechanical outputs in strength exercises and in PP (n = 6). Bibliometrics analysis of the PP-related scientific output revealed that, despite having already become a paralympic sports discipline in 1984, only in the last few years, PP has been attracting a lot of interest from the community of researchers, with the first scholarly contribution dating back to 2012, and with more than one-third of the scientific output being published this year (2022). As such, this scholarly discipline is quite recent and young. Moreover, the community dealing with this topic is poorly interconnected, with most authors contributing to just one article, and with one single author being a hub node of the author network. Distributions of the number of articles and the authors/co-authors were found to be highly asymmetrical, indicating that this research is still in its infancy and has great room as well as great potential to grow. Reflecting this, many research topics are also overlooked and underdeveloped, with the currently available evidence being based on a few studies.
