Effects of Plyometric Jump Training on Measures of Physical Fitness and Sport-Specific Performance of Water Sports Athletes: A Systematic Review with Meta-analysis

et al. 2022

Background A growing body of literature is available regarding the effects of plyometric jump training (PJT) on measures of physical fitness (PF) and sport-specific performance (SSP) in-water sports athletes (WSA, i.e. those competing in sports that are practiced on [e.g. rowing] or in [e.g. swimming; water polo] water). Indeed, incoherent findings have been observed across individual studies making it difficult to provide the scientific community and coaches with consistent evidence. As such, a comprehensive systematic literature search should be conducted to clarify the existent evidence, identify the major gaps in the literature, and offer recommendations for future studies. Aim To examine the effects of PJT compared with active/specific-active controls on the PF (one-repetition maximum back squat strength, squat jump height, countermovement jump height, horizontal jump distance, body mass, fat mass, thigh girth) and SSP (in-water vertical jump, in-water agility, time trial) outcomes in WSA, through a systematic review with meta-analysis of randomized and non-randomized controlled studies. Methods The electronic databases PubMed, Scopus, and Web of Science were searched up to January 2022. According to the PICOS approach, the eligibility criteria were: (population) healthy WSA; (intervention) PJT interventions involving unilateral and/or bilateral jumps, and a minimal duration of ≥ 3 weeks; (comparator) active (i.e. standard sports training) or specific-active (i.e. alternative training intervention) control group(s); (outcome) at least one measure of PF (e.g. jump height) and/or SSP (e.g. time trial) before and after training; and (study design) multi-groups randomized and non-randomized controlled trials. The Physiotherapy Evidence Database (PEDro) scale was used to assess the methodological quality of the included studies. The DerSimonian and Laird random-effects model was used to compute the meta-analyses, reporting effect sizes (ES, i.e. Hedges’ g) with 95% confidence intervals (95% CIs). Statistical significance was set at p ≤ 0.05. Certainty or confidence in the body of evidence for each outcome was assessed using Grading of Recommendations Assessment, Development, and Evaluation (GRADE), considering its five dimensions: risk of bias in studies, indirectness, inconsistency, imprecision, and risk of publication bias. Results A total of 11,028 studies were identified with 26 considered eligible for inclusion. The median PEDro score across the included studies was 5.5 (moderate-to-high methodological quality). The included studies involved a total of 618 WSA of both sexes (330 participants in the intervention groups [31 groups] and 288 participants in the control groups [26 groups]), aged between 10 and 26 years, and from different sports disciplines such as swimming, triathlon, rowing, artistic swimming, and water polo. The duration of the training programmes in the intervention and control groups ranged from 4 to 36 weeks. The results of the meta-analysis indicated no effects of PJT compared to control conditions (including specific-active controls) for in-water vertical jump or agility (ES = − 0.15 to 0.03; p = 0.477 to 0.899), or for body mass, fat mass, and thigh girth (ES = 0.06 to 0.15; p = 0.452 to 0.841). In terms of measures of PF, moderate-to-large effects were noted in favour of the PJT groups compared to the control groups (including specific-active control groups) for one-repetition maximum back squat strength, horizontal jump distance, squat jump height, and countermovement jump height (ES = 0.67 to 1.47; p = 0.041 to < 0.001), in addition to a small effect noted in favour of the PJT for SSP time-trial speed (ES = 0.42; p = 0.005). Certainty of evidence across the included studies varied from very low-to-moderate. Conclusions PJT is more effective to improve measures of PF and SSP in WSA compared to control conditions involving traditional sport-specific training as well as alternative training interventions (e.g. resistance training). It is worth noting that the present findings are derived from 26 studies of moderate-to-high methodological quality, low-to-moderate impact of heterogeneity, and very low-to-moderate certainty of evidence based on GRADE.

“…Сравнение размеров тела спортсменок сборной команды страны с межгрупповыми шкалами оценки телосложения взрослых женщин [Мартиросов, 1986] показало, что длина тела синхронисток выше средних значений для своего пола, а масса тела -ниже. При сравнении росто-весовых показателей элитных российских синхронисток с аналогичными данными зарубежных исследований последних лет [Kim et al, 2019, Bellver et al, 2021 мы обнаружили, что по длине тела отечественные синхронистки схожи со спортсменками сборной Испании (169,6±0,98 и 170,3±6,1, соответственно), тогда как в весе они им уступают (54,0±0,62 и 56,3±5,8, соответственно). Представительницы сборной Кореи значительно отстают в росте (165,4±5,70) от своих коллег, при этом масса тела (53,6±5,08) имеет схожую величину, что у российских синхронисток.…”

Material and methods. The sample of 50 people consisted of female athletes of three age groups: junior (9-10 years old), senior (14-15 years old) and the Russian national team (over 18 years old). In this cross-sectional study, we used total body dimensions (according to V.V. Bunak), body mass components (ac-cording to J. Matiegka’s formulas and bioimpedance method), body proportions (according to P.N. Bashkirov’s method), body shape (by somatoscopy), somatotype (by the Heath-Carter and Shtefko-Ostrovsky) and biological age (by dental and sexual maturity). Results. In terms of physical development, artistic swimmers (girls) do not differ significantly from their peers who do not go in for sports. The body height of the national team athletes is higher than the average values for their gender, and the body weight is lower. Under the influence of training loads in young artistic swimmers, there is a slight decrease in the fat component and an increase in the muscle one. Russian elite artistic swimmers have a lower level of development of adipositythan athletes of the national teams of Ko-rea and Spain. The muscular component of the Russian artistic swimmers may indicate overwork. The analy-sis of the variability of body proportions of artistic swimmers of different age groups testifies to the target-ed selection to the national team in the terms of longitudinal body dimensions. At the present stage of development of artistic swimming, the selection of retardant athletes is taking place. It was revealed that somatotypes with significant mesomorphism prevail in younger and older age groups, while the athletes of the national team belong to the ectomorphic body type with various variations of two other components of the somatotype. Conclusion. The study of morphological indicators made it possible to form an idea of the importance of the somatotype and body proportions for artistic swimming, which, in the combination with other necessary qualities, will increase the efficiency of selection and control of the training process.

Bone-forming cells build mineralized microstructure and couple with bone-resorbing cells, harmonizing bone mineral acquisition, and remodeling to maintain bone mass homeostasis. Mitochondrial glycolysis and oxidative phosphorylation pathways together with ROS generation meet the energy requirement for bone-forming cell growth and differentiation, respectively. Moderate mechanical stimulations, such as weight loading, physical activity, ultrasound, vibration, and electromagnetic field stimulation, etc., are advantageous to bone-forming cell activity, promoting bone anabolism to compromise osteoporosis development. A plethora of molecules, including ion channels, integrins, focal adhesion kinases, and myokines, are mechanosensitive and transduce mechanical stimuli into intercellular signaling, regulating growth, mineralized extracellular matrix biosynthesis, and resorption. Mechanical stimulation changes mitochondrial respiration, biogenesis, dynamics, calcium influx, and redox, whereas mechanical disuse induces mitochondrial dysfunction and oxidative stress, which aggravates bone-forming cell apoptosis, senescence, and dysfunction. The control of the mitochondrial biogenesis activator PGC-1α by NAD+-dependent deacetylase sirtuins or myokine FNDC/irisin or repression of oxidative stress by mitochondrial antioxidant Nrf2 modulates the biophysical stimulation for the promotion of bone integrity. This review sheds light onto the roles of mechanosensitive signaling, mitochondrial dynamics, and antioxidants in mediating the anabolic effects of biophysical stimulation to bone tissue and highlights the remedial potential of mitochondrial biogenesis regulators for osteoporosis.
