Figure 1.
Examples of T2-weighted magnetic resonance images of hip (upper) and thigh (lower) regions at pre-exercise (left), after BS (middle), and after PSJ (right).
GM, the gluteus maximus; Vas, the vasti muscles; RF, the rectus femoris muscle; Add, the hip adductors; Ham, the hamstrings. A, anterior; P, posterior; R, right; L, left.
Figure 2.
Time course of each joint torque and angle during back squat and plyometric squat jumping.
BS, back squat; PSJ squat jumping. Data from 1 subject are presented. The solid and dashed lines indicate the torque and angle, respectively. Positive values indicate extension. Time is represented as percentage of analysis time, i.e., from start to end of repetition in BS and from touch down to take off in PSJ.
Table 1.
Comparison of the joint torque between BS and PSJ (N · m).
Table 2.
Comparison of the joint angular velocity between BS and PSJ (deg/s).
Table 3.
Comparison of the joint power between BS and PSJ (Watt).
Figure 3.
The % activated area of each muscle along its length as a function of the distance from the greater trochanter.
The closed and open circles indicate back squat and plyometric squat jumping, respectively. GM, the gluteus maximus; Vas, the vasti muscles; RF, the rectus femoris muscle; Add, the hip adductors; Ham, the hamstrings. There was no significant interaction between the region and exercise condition.
