“…Most studies report the subjects' age, except for one (Cherepov and Shaikhetdinov, 2016), and only one study reported the age range of the subjects (Tomljanović et al, 2011). An analysis of age reports in seven studies found that the age range of the subjects ranged from 9.6 years to 25 years (Oliver and Brezzo, 2009;Sander et al, 2013;Elbadry, 2014;Alonso-Fernández et al, 2017;Yildiz et al, 2019;Baron et al, 2020;Keiner et al, 2020); (5) Body Mass Index. Most studies reported the height and weight of the subjects (Oliver and Brezzo, 2009;Tomljanović et al, 2011;Sander et al, 2013;Elbadry, 2014;Alonso-Fernández et al, 2017;Yildiz et al, 2019;Keiner et al, 2020), only two studies reported the BMI of the subjects (Alonso-Fernández et al, 2017;Baron et al, 2020), and only one study did not state the weight, height, BMI of the subjects (Cherepov and Shaikhetdinov, 2016).…”

“…The nine included studies' intervention characteristics were reported based on the following aspects: (1) Training length. The shortest intervention length is 8 days (Sander et al, 2013) and the longest being 10 months (Keiner et al, 2020); (2) Duration of each training session. Most studies reported the duration of each training session (Oliver and Brezzo, 2009;Elbadry, 2014;Alonso-Fernández et al, 2017;Yildiz et al, 2019;Baron et al, 2020;Keiner et al, 2020), only three studies did not state the duration (Tomljanović et al, 2011;Sander et al, 2013;Cherepov and Shaikhetdinov, 2016).…”

“…On the other hand, a new exercise training method that has recently received much attention to developing athletes' physical fitness is functional training (Feito et al, 2018). Several studies have confirmed that functional training can enhance speed (Tomljanović et al, 2011;Sander et al, 2013;Alonso-Fernández et al, 2017;Yildiz et al, 2019;Baron et al, 2020;Keiner et al, 2020), muscular strength (Oliver and Brezzo, 2009;Tomljanović et al, 2011;Elbadry, 2014;Cherepov and Shaikhetdinov, 2016;Keiner et al, 2020), power (Tomljanović et al, 2011;Alonso-Fernández et al, 2017;Yildiz et al, 2019;Keiner et al, 2020), balance (Oliver and Brezzo, 2009;Elbadry, 2014;Yildiz et al, 2019), body composition (Oliver and Brezzo, 2009;Tomljanović et al, 2011;Alonso-Fernández et al, 2017), agility (Tomljanović et al, 2011;Cherepov and Shaikhetdinov, 2016;Yildiz et al, 2019), flexibility (Yildiz et al, 2019) and muscular endurance (Oliver and Brezzo, 2009). Additionally, other research has discovered positive effects of functional training on physical fitness in football players (Oliver and Brezzo, 2009;Sander et al, 2013;Baron et al, 2020;Keiner et al, 2020), handball players (Elbadry, 2014;Alonso-Fernández et al, 2017), martial artists (Cherepov and Shaikhetdi...…”

Effect of Functional Training on Physical Fitness Among Athletes: A Systematic Review

et al. 2021

There is evidence that functional training is beneficial for the overall physical fitness of athletes. However, there is a lack of a systematic review focused on the effects of functional training on athletes' physical fitness. Thus, the aimed of the present review is to clarify the effects of functional training on physical fitness among athletes. In accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyzes (PRISMA) Statement guidelines, the systematic search of PubMed, SCOPUS, EBSCOhost (SPORTDiscus), and CINAHL Plus databases was undertaken on the 2nd November 2020 to identify the reported studies, using a combination of keywords related to functional training, physical fitness, and athletes. From the 145 studies, only nine articles met all eligibility criteria and were included in the systematic review. The assessment was performed on the Pedro scale, and the quality of the study included in the nine studies was fair (ranging from 3 to 4). The results showed that speed (n = 6) was the aspect of physical fitness studied in functional training interventions, followed by muscular strength (n = 5), power (n = 4), balance (n = 3), body composition (n = 3), agility (n = 3), flexibility (n = 1) and muscular endurance (n = 1). Existing evidence concludes that functional training significantly impacts speed, muscular strength, power, balance, and agility. Furthermore, there are still limit numbers of evidence showing effect of functional training on flexibility and muscular endurance. In contrast, no significant improvement was found in body composition where functional training was conducted.Systematic Review Registration:https://www.crd.york.ac.uk/prospero, identifier: CRD4202123092.

Can isometric testing substitute for the one repetition maximum squat test?

When measuring maximum strength, a high accuracy and precision is required to monitor the training adaptations. Based on available reliability parameters, the literature suggests the replacement of the one repetition maximum (1RM) by isometric testing to save testing time. However, from a statistical point of view, correlation coefficients do not provide the required information when aiming to replace one test by another. Therefore, the literature suggests the inclusion of the mean absolute error (MAE), the mean absolute percentage error (MAPE) for agreement analysis. Consequently, to check the replaceability of 1RM testing methods, the current study examined the agreement of isometric and dynamic testing methods in the squat and the isometric mid-thigh pull. While in accordance with the literature, correlations were classified high r = 0.638–0.828 and ICC = 0.630–0.828, the agreement analysis provided MAEs of 175.75–444.17 N and MAPEs of 16.16–57.71% indicating an intolerable high measurement error between isometric and dynamic testing conditions in the squat and isometric mid-thigh pull. In contrast to previous studies, using MAE, MAPE supplemented by CCC and BA analysis highlights the poor agreement between the included strength tests. The recommendation to replace 1RM testing with isometric testing routines in the squat does not provide suitable concordance and is not recommended.

Background Strength and speed are two major factors that determine performance in basketball players especially sprinting, jumping and change of direction. This study examined relationships of maximal strength in the front squat and the deadlift with basketball-specific sprint and jump performance tests that are commonly used in test batteries of athletic diagnostics. Materials and methods In all, 42 youth male elite basketball players (age: 14.7 ± 2.4 years, age range: 13–18 years, height: 179.1 ± 15.3 cm, weight: 69.8 ± 19.2 kg) volunteered to take part in the present study. The one repetition maximum (1 RM) in the front squat and deadlift were used to determine maximum strength. Countermovement jump (CMJ) and standing long jump were evaluated to determine jump performance and 5, 10, and 20 m linear sprint as well as agility T‑test were performed to determine sprint performance. Pearson correlation analysis was used to assess the relationships between strength and jump and sprint performance. Results Strong positive correlations were found between maximal strength and jump heights (r = 0.85–0.91, p < 0.001) and strong negative correlations were determined between maximal strength and measured sprint times r = (−0.71 to −0.85, p < 0.001). Conclusion The measured maximal strength in the front squat and deadlift seem to be good predictors for basketball-specific jump and sprint performance. From this, it seems to be beneficial to include training of maximal strength via front squat and deadlift into training routines as well as performance diagnostics.
