“…The quality of the studies ranged between 3 (poor) to 10 (excellent) and all the studies failed in blinding of subjects except one paper (17), failed in therapist blinding except 2 papers (17,22) and failed in assessors blinding except 3 papers (17,19,23). According to the follow up time, 5 papers evaluated the immediate effect of the interventions (17,20,(23)(24)(25), 8 papers were assessed a duration of less than 3 months (short term) (13-16, 18, 19, 22, 24), and only one contained a follow up of more than 3 months (long term) (21). In total, 60 exercises were included containing traditional exercises (n = 11), core stability Table II.…”

“…Four papers contained control groups with no types of exercises (13,15,21,22). Changes in the muscles along with the interventions were evaluated with muscular thickness via ultrasonography (13)(14)(15)(16)(17)(18)(19)(20)(21)(22) and muscular electrical activation via electromyography (19,(23)(24)(25)(26).…”

“…Two studies with score range 3-5 resulted in a significant improvement while doing unstable exercises (p = 0.04 for flexion and p = 0.01 for extension) or putting body in an unstable position (p < 0.005) (24,26). Another article with good quality (score: 6) concluded that yelling or grunting (verbal activity) highly improved muscle activation (p = 0.024) (23).…”

Objective. The aim of this study was to systematically review current literature on the effectiveness of various exercises and modifications on thickness and electrical activity of abdominal muscles using ultrasonography and electromyography in healthy adults.Methods. An electronic search was carried out on PubMed, Web of science, ProQuest, Google Scholar, Cochrane and Science Direct databases covering published studies from inception until December 2022. Fourteen papers were then included according to following inclusion criteria: 1) studies assessing abdominal exercises; 2) containing control and intervention groups; 3) conducted on young and healthy samples; 4) full texts being available in English; 5) containing the analysis of at least one of the four abdominal muscles through electromyography or ultrasonography. Results. The main findings would suggest that stability challenges, rotatory exercise, combination of upper and lower limb movements, sensory cueing and grunting techniques such as Ki-hap make significant improvements in muscle structure and activity. Conclusions. Despite the averagely fair quality of included papers and difficulty to reach a conclusion with inadequate data, our review suggests that new modifications of both traditional and core exercises can cause improvements in abdominal muscle thickness or activity with the aim of focusing on control and coordination of muscles. Study registration. The protocol of the present systematic review is registered in the PROSPERO (CRD42022377864).

“…Verbal encouragement during isokinetic assessment for knee flexors and extensors showed improvement in muscle power, activation, and endurance (1). Regarding electromyographic assessment, verbal encouragement improves abdominal muscle activation during crunch exercise in healthy individuals (2) . Calatayud et al report that different verbal stimuli brought about better electromyographic responses during a maximal voluntary isometric contraction (3,4) .…”

Background: It’s known that the frontal plank exercise presents a greater demand of the biomechanics stability and it is largely prescribed and used during the practice by the health professionals, known the verbal encouragement influence on corporal stability through the professional feedback can contribute positively in the clinical, social and scientific field. Objectives: Verify the verbal encouragement influences on corporal stability during the traditional frontal plank exercise in young health adults. Methods: Subjects were selected in an intentional non-probabilistic way, constituting a sample of young male adults, with normal body mass index, moderate to advanced self-reported physical activity level and with, at least, six months of previous resistance training experience. Participants were instructed to perform the traditional frontal plank for 30 seconds keeping all the items in the description of the technique, no command was given besides the following verbal incentives: “Contract, stabilize, force, maintain and force”. After the execution, the professional self-reported his perception of body stability, writing down his answers on the control form. Results: The sample consisted of 10 participants, with a mean age of 30.6 years (±4.03). All male, white and with no history of trauma/injury. For individuals with less than one time of weekly physical exercise, verbal encouragement showed a positive response in the perception of body stability. As for the remainder, who practiced physical exercise with greater recurrence, the evaluator's perception of high stability was given both with and without verbal encouragement. Conclusion: This pilot study showed that in individuals with less time of weekly physical exercise, verbal encouragement showed a positive response in body stability, changing from moderate to high. But, the individuals with more time of practice, the verbal encouragement showed no response in the perception of body stability.

“…[24][25][26] Similar forms of forced exhalation and vocalization, such as the ki-hap used in taekwondo, have been shown to improve upper extremity muscle force, corticospinal excitability and trunk muscle activation. [27][28][29][30][31][32] The trunk plays a key role in the kinetic chain of the baseball pitch, working with the legs to produce over half of the kinetic energy, which is transferred to the upper extremities during the acceleration phase of the throw. 14,33 Thus, it seems likely that the increased velocity found during grunting in the overhead tennis serve could also be produced during overhead baseball throwing.…”

The purpose of this study was to determine the effect of grunting on overhead throwing velocity in collegiate baseball pitchers. A repeated-measures experimental design was used. Twenty-four division III collegiate baseball pitchers with a mean age of 20.3 ± 1.6 years voluntarily participated in the study. Subjects were shown a video demonstration of a pitcher grunting during the acceleration phase of pitching and asked to replicate the technique during three practice throws. Corrective verbal feedback from researchers was given regarding the timing of the grunt during practice throws. Subjects then performed randomized sets (3 grunting and 3 non-grunting trials) of overhead throws from a standard pitching mount in the stretch position with maximum effort. Throwing velocities were measured with a calibrated radar gun. Paired-samples t-tests were used to compare average throwing velocities between the grunting and non-grunting trials at the 0.05 alpha level. Mean overhead throwing velocity was significantly higher during the grunting trials than the non-grunting trials. Age, height, weight, and handedness had no impact on the effect of grunting on overhead throwing velocity. Grunting offers a simple, immediate means of enhancing overhead throwing velocity in the collegiate baseball pitching population. Additional research is needed to determine the effects in populations of greater or lesser skill.
