Effects of six weeks donkey kick and squat resistance exercises on gluteal adiposity, muscle strength, and muscle bulk of young Nigerian female adults: A randomized controlled trial

Abstract

Background: Rounded protruding gluteus has been asserted to be an important feature of feminine beauty and self-image. Currently, there is large influx of gymnasiums to achieve this end as claimed by gym operators amid the dearth in literature to support their claims. Aim: The aim of this study was to provide an empirical evidence to support or disprove claims about the effectiveness of resistance training exercises such as squats and donkey kick on the gluteal muscles. Materials and Methods: Randomized controlled trial involving 111 young females, aged 18–30 years, were equally assigned into the squat group (SG), donkey kick group (DKG), and control group (CG) using table of random numbers method. Outcomes, such as gluteal muscle strength (GMS), gluteal muscle bulk (GMB), and gluteal adiposity (GA), were assessed at baseline, third week, and sixth week and analyzed descriptively and inferentially (α = 0.05). Result: The post-intervention across group comparison revealed a significant difference in right (F = 4.829, P = 0.010) and left (F = 7.252, P = 0.001) GA, right (F = 12.467, P < 0.0001) and left (F = 10.235, P < 0.0001) GMS, and in the GMB (F = 8.280, P = 0.001). The post hoc test showed that the SG had the most profound effect in increasing GMS and GMB, whereas the DKG had a superlative effect on GA. Conclusion: Six weeks resistant training using squats and donkey kick can be used to improve gluteal muscle characteristic by building GMB, GMS and reducing GA of young female adults.
