“…The direct effect of IT on the BM results in a decrease in its contraction ability, stabilizing the elbow joint during the catch stage in freestyle swimming stroke 71 – 73 . Additionally, the autonomous contraction ability of muscles is closely related to muscle electromyography (EMG) activity 22 , 74 – 77 . It remains unknown whether the IT-induced improvement in MVC for swimmers with EP also influences muscle EMG activity.…”

The effects of IT and R.I.C.E. treatment on arm muscle performance in overhead athletes with elbow pain (EP) have been partially validated. However, there is a lack of research evidence regarding the efficacy of these two methods on arm muscle performance among swimmers with EP. The aim of this study was to investigate the trends and differences in the effects of IT and R.I.C.E. treatment on arm muscle performance among swimmers with EP. The main outcomes were the time effects and group effects of interventions on muscle voluntary contraction (MVC). Sixty elite freestyle swimmers from Tianjin, China, voluntarily participated in the study and completed a 10-week intervention program. Swimmers with EP in the IT group showed a positive trend in MVC, with an approximately 2% increase, whereas the MVC of subjects in the R.I.C.E. treatment group and control group decreased by approximately 4% and 5%, respectively. In comparison, the effects of the IT intervention on the MVC of the triceps and brachioradialis muscles in swimmers with EP were significant (p = 0.042 < 0.05, p = 0.027 < 0.05). The mean MVC value of the IT group (0.60) was greater than that of the other two groups (0.51, 0.50). IT has a beneficial impact on the MVC performance of the triceps and brachioradialis muscles in swimmers with EP. It is recommended that professionals consider incorporating IT into regular training routines to mitigate the risk of EP issues. Future research should examine the effectiveness of both interventions on hand-grip strength and completion time in 50-m freestyle swim drills in order for swimmers with EP to return to this sport.

“…Previous studies have shown the adaptive changes in strength of the periscapular muscles in swimmers after swim training, which may be associated with SD and altered neuromuscular control. There were more competitive swimmers exhibiting SD due to muscle fatigue after swim training than before training 25 , 26 Swimmers also demonstrate a decrease in SA activity and an increase in internal rotation and anterior tilting of the scapula during scaption after maximal-effort stroke exercise 27 The possible reason was SA fatigue since SA alternately played as a scapular stabilizer and protractor throughout the swimming stroke. However, more internal rotation and anterior tilting of the scapula with higher activity of the SA during scaption were noticed in swimmers than in nonpractitioners 12 The increases in SA activity didn’t favor tilting the scapula posteriorly and rotating it externally may be due to insufficient strength.…”

The passive stiffness and strength of periscapular muscles may affect scapulohumeral control, especially in overhead athletes due to sports-specific training. This study tried to assess the relationship between the passive stiffness and strength of periscapular muscles, scapulohumeral kinematics and neuromuscular control during scaption in swimmers. Ten male adolescent competitive front-crawl swimmers were recruited. The passive stiffness and strength of periscapular muscles were measured in standard postures by a hand-held myotonometer and dynamometer, respectively. Surface electromyography and electromagnetic tracking systems were synchronized to record the muscle activities and scapulohumeral kinematics during scaption. Correlations between the passive stiffness or strength of periscapular muscles and the kinematics or muscle activity were examined by Spearman's rank correlation coefficient. The maximal strength of periscapular muscles correlated positively with the ranges of upward and external rotation of the scapula and negatively with muscle activity during scaption. Passive stiffness of periscapular muscles was associated with the downward rotation of the scapula and triggered an increase in muscle activity. Increased passive stiffness or decreased strength in the periscapular muscles may affect their role in controlling the scapular rotation and contribute to compensation from adjacent muscles. Our findings suggest that when attempting to evaluate scapular behavior, it may be beneficial to examine muscle strength and passive stiffness of periscapular muscles.

This paper describes the most frequent cases of musculoskeletal system injuries in professional swimmers, based on the scientifi c journal articles analysis. The main causes of shoulder and knee joints injuries in athletes who use various swimming techniques are presented. It is shown that training the correct movement pattern allows to reliably prevent damage to the musculoskeletal system. The study conducted focuses on the further search for new methods for the rehabilitation of swimmers, including osteopathic correction, both independently and in combination with other types of exposure.

Biomechanical analysis of the shoulder of swimmers after a maximal effort test

Abstract: A maximal 3-min effort test resulted in altered scapular biomechanics. More studies are needed to verify if the changes correspond to a risk factor for injuries.
