Comparison of muscle activation level during performing modified RAZOR curl and Nordic curl exercises in strength training (IR)

The aim of this study is to determine muscle activation level between two different exercise technique (modified RAZOR curl and Nordic curl) on biceps femoris, semitendinosus, erector spinae and lower rectus abdominis. Twenty-five recreationally active male university students had voluntarily partic...

Twenty-five recreationally active male university students had voluntarily participated to serve the purpose of this study. Muscle activities during both concentric and eccentric contractions were measured using electromyography (EMG). The raw data obtained were than normalized to determine the rate of maximum voluntary isometric contraction (MVIC). Analysis of the result indicated that there was significant difference between modified RAZOR curl and Nordic curl exercises, in term of muscle activation of biceps femoris during concentric and eccentric contraction. However no significant differences was found either on concentric or eccentric muscle contractions for both exercises in other muscle groups. Finding of the study also reveal that the RAZOR curl technique produced greater maximal voluntary isometric contraction. Based on the results, it was concludes that Nordic curl is a better exercise technique for the training of hamstring musculature, due to higher concentric and eccentric activation on biceps femoris and semitendinosus. However modified RAZOR curl was more appropriate to be used for training aiming at higher functionality, with better activation of supporting muscles such as the core muscles. For practical application both exercises are suggested to be used interchangeably for better muscle adaptation and stimulus apart from avoiding overuse injury. 2015 thesis https://ir.upsi.edu.my/detailsg.php?det=279 https://ir.upsi.edu.my/detailsg.php?det=279 text eng closedAccess Masters Universiti Pendidikan Sultan Idris Fakulti Sains Sukan dan Kejurulatihan N/A
