The Effect of Back Squat Depth and Load on Lower Body Muscle Activity in Group Exercise Participants
Description
Each file shows the EMG data for one study participant. There were 10 participants in total. Four muscles were analysed: Gluteus Maximus (GM), Biceps Femoris (BF), Vastus Lateralis (VL), Lateral Gastrocnemius (LG) For each muscle, mean and peak EMG data were obtained There were 4 squat conditions: 90 degree knee angle, 23% bodyweight load (90D 23L) 90 degree knee angle, 38% bodyweight load (90D 38L) 125 degree knee angle, 23% bodyweight load (125D 23L) 125 degree knee angle, 38% bodyweight load (125D 38L) For each condition, 5 squats were analysed. Each repetition was divided into an eccentric (E) and concentric (C) phase. The eccentric phase of repetition 1 is abbreviated as 1:E etc. Each participant also performed 5 Countermovement Jumps (CMJs) The squat data were normalised against the CMJ data
