“…Our present study’s results show that gait speed has no effect on the selective strengthening of the gluteus medius. The study conducted by Sin et al 11 ) also noted that no change in the muscle activity of the gluteus medius was found between gait speeds changes of 3.5 and 5.5 m/s. In particular, while performing gait with weight loading on the arm, changes in the muscle activities of the latissimus dorsi and the gluteus maximus, which are the principal muscles of the Posterior Oblique Sling Theory proposed by Bermark 12 ) , were found to be significant, but no change in the muscle activity of the gluteus medius was found.…”

[Purpose] The present study aimed to determine the changes in the muscle activities of the gluteus medius, latissimus dorsi, and gluteus maximus at different gait speeds, to collect basic data for the study of the gluteus medius. [Subjects and Methods] The subjects were 18 young and healthy male adults whose mean age, height, and weight were 26.4 years, 173.37 cm, and 72.5 kg, respectively. Electromyograpy was used to measure the maximum voluntary isometric contraction of each muscle three times and the values averaged. Then, the subjects walked on a treadmill at gait speeds of 1.5 m/s, 2.5 m/s, and 3.5 m/s and the muscle activity of each muscle was measured. [Results] The gluteus medius showed no significant difference in muscle activity among the different gait speeds. [Conclusion] For selectively strengthening the gluteus medius, to establish the external stability of the pelvis during walking, weight loading or sloped treadmills are effective interventions. However, different gait speeds exert no significant effect on the selective strengthening of the gluteus medius.

“…4 The transfer of mechanical forces between the latissimus dorsi and gluteus maximus may explain why there was no difference between the peak amplitude of the latissimus dorsi and second burst of the gluteus maximus. 4,10,66,67 When examining kinematics, maximum pelvic external rotation occurs at initial contact, and maximum hip extension occurs in a bimodal pattern: just prior to toe-off during the stance phase, and during the second half of the swing phase. 68 The primary action of the gluteus maximus is to extend and externally rotate the hip, and therefore the muscle activation patterns of this muscle coincide with the kinematic movement of the hip joint.…”

“…68 The contralateral latissimus dorsi, which acts to extend, adduct, and internally rotate the glenohumeral joint, and the gluteus maximus provide a pathway for uninterrupted mechanical transmission between the pelvis and the trunk during trunk rotation, gait and running. 4,10,66,67 Additionally, the posterior oblique sling system provides dynamic lumbopelvic stability and helps deliver power from the lower to the upper body. 4,10,66,67 Daneels and colleagues 69 Overall, the Posterior Oblique Sling exhibited no differences in any measured variable (EMG onset , EMG offset , EMG peak , EMG amp ) between high economy and low economy runners.…”

“…Limited work, however, has been done to establish the interactions of muscles bilaterally across the kinetic chain or the interactions of muscles bilaterally during a particular portion of the gait cycle. During gait and running, the sling systems aid in stability of the body and in promoting a reciprocal gait pattern between the upper and lower extremities 2,10 , with a general tendency towards a more synchronous activation of all muscles at higher running speeds. 11 For the studies identified that employed electromyography (EMG) during running gait, data were analyzed ipsilaterally using percentages of the gait cycle.…”

Dissertation supervised by Professor Joseph F. Signorile. No. of pages in text. (68) Background and Purpose: Human locomotion requires characteristic muscle activation timing patterns that work in a defined fashion along a kinetic chain. Sling systems are chains of muscles and innervating fascia that facilitate sequential muscle activation patterns during movement. The purpose of this study was to examine four sling systems across a running gait cycle and to determine how they might differ between runners with high and low running economy. Participants: Twenty-five recreational runners (11M, 14F, height = 1.73 ± .07 m, mass = 70.3 ± 11.7 kg, age = 28.6 ± 5.1 years) completed this study. Methods: Recreational runners completed a running economy test and were classified as high economy or low economy based on published normative data. On a separate testing day, runners completed overground running trials at a 10-km race pace and slow running pace. Surface electromyography was used to measure muscle activation during run trials for four sling systems: the Posterior Oblique Sling (POS: gluteus maximus and contralateral latissimus dorsi), the Anterior Oblique Sling (AOS: external oblique and contralateral adductors), the Lateral Sling (LAT: gluteus medius, tensor fascia latae (TFL), and contralateral quadratus lumborum (QL)), and the Deep Longitudinal Sling (LONG: tibialis anterior (TA), peroneus longus, biceps femoris (BF), multifidus, and erector spinae (ES)). Mixed-Design ANOVAs were conducted to determine differences among sling systems and between groups in muscle onset time (EMG onset), muscle offset time (EMG offset), peak amplitude (EMG amp), and time of peak amplitude (EMG peak). Peak times and amplitudes for the muscles of the AOS could not be established as these muscles displayed nearly constant activation throughout the gait cycle. Results: Significant main effects were observed in the POS, LONG, and LAT at both the 10-km race pace and slow running pace for EMG onset, EMG offset , EMG peak , and EMG amp. Differences between high economy and low economy runners were observed for ES EMG onset Burst 3, ES EMG peak Burst 3, ES EMG amp Burst 3,BF EMG onset Burst 1, BF EMG peak Burst 1, BF EMG offset Burst 2, BF EMG peak Burst 2, BF EMG peak Burst 3, BF EMG amp Burst 1, and TA EMG peak at the slow running speed. At the 10-km race pace, differences between high economy and low economy runners were observed for TFL EMG onset Burst 2, QL EMG offset Burst 1, QL EMG peak Burst 2, and QL EMG onset Burst 3. Discussion and Conclusion: Muscles in the POS, LAT, and LONG work in defined sequential and synchronous patterns across the gait cycle with significant variability between high economy and low economy runners.

Compared to their sedentary peers, older track athletes demonstrate a superior ability to negate the normal age-related changes in gait mechanics known to attenuate maximal walking speed performance with age. Sports-specific exercises commonly utilized to affect this end may be appropriately scaled to benefit a wider subset of older adults. Optimal dosing of resistance training to maximize gluteus maximus functional fitness, accompanied by gait reeducation to augment motor patterns facilitating optimal peak trailing leg extension and push-off intensity, create a redundancy in walking capacity likely to prolong functional independence for beneficiaries of this targeted intervention.
