Assessment of asymmetry at different intensities between conventional and paralympic powerlifting athletes

Evaluation of the Training Session in Elite Paralympic Powerlifting Athletes Based on Biomechanical and Thermal Indicators

“…This could be explained by the lesser control that the non-dominant side would have in relation to the dominant side. In this direction, other studies showed asymmetry, mainly with higher intensities, with higher values for the non-dominant side, a fact observed in our study [ 23 , 32 ].…”

“…Monitoring training based on temperature is crucial, especially for athletes with physical disabilities who may experience overloading in affected body segments, impacting the performance of certain movements. The use of orthoses, prostheses, and wheelchairs may potentiate injuries and hinder the maintenance of body symmetry, a crucial aspect in competitions and training, particularly in Paralympic powerlifting [ 23 , 49 ]. Our data showed that Paralympic powerlifting training with high loads shows temperatures in a safe range (<1.6 °C) despite thermal asymmetries.…”

“…Our study showed a higher velocity in the non-dominant limb compared to the dominant one. Some studies, which evaluated the velocity in Para powerlifting, observed differences, notably with higher intensities, where the non-dominant side presented higher velocity than the dominant side [ 23 , 51 , 52 ]. This could be explained by the lesser control that the non-dominant side would have in relation to the dominant side.…”

“…Asymmetries tend to interfere with sports performance, and this relationship between asymmetry and worsening performance has been reported in other sports, with an increased risk of injury [ 20 , 21 , 22 ]. On the other hand, some studies have shown that training can reduce asymmetries [ 23 , 24 ]. Given this context, some challenges arise in relation to Paralympic powerlifting (PP), such as the rules that do not allow asymmetries in movement, the intensity of training, and its consequences on fatigue and increases in asymmetries, whether in movement or thermals.…”

Biomechanics research on laterality effect between dominant and non-dominant during double roundhouse kick in the competitive taekwondo

“…GPower 3.1.9.7 is utilized to evaluate the predicted sample size. A correlation analysis using a larger effect size of d = 0.7 required at least 11 participants at a significance level of α = 0.05 and a statistical power (1- β ) of 80 % [ 33 , 34 ]. The participants of this study include 12 male athletes from the taekwondo specialized training team (19.6 ± 2.0 years, 180 ± 7.3 cm, 70 ± 9.8 kg, and the average training history is 3.8 ± 2.0 years).…”
