The purpose of this study was to determine the neuromuscular activation patterns of the quadriceps femoris (QF) synergists including the vastus intermedius (VI) during squat movement. For 15 healthy men, surface electromyography (EMG) was recorded at VI, vastus lateralis (VL), vastus medialis (VM) and rectus femoris (RF) during the repetitive squat movements. The squat movement started upright posture. This movement consisted of eccentric (ECC) phase, isometric (ISO) phase at the bottom, and concentric (CON) phase with knee joint angle between 0° to 90°. The root mean square (RMS) of the EMG signals during three phases was calculated for knee joint angles ranging from 15° to 90°. Each ECC and CON phase was further divided into three subcategories. The RMS during squat was normalized by that of 15° to 40° during the ECC phase for all muscles. During the squat movement, a significant muscle-by-angle interaction in normalized RMS was found (P < 0.05). The normalized RMS of VI was signifi cantly higher than that of the VL and VM at all subcategories during ECC phase and ISO phase (P < 0.05). These results suggest that the VI plays an important role in the fl exed knee position during squat movement. This uncovered finding may help establishment of future effective therapeutic programs for dysfunction of QF related knee joint disorders.

The relationship between the thigh muscle composition and the sprinting performance was investigated in 11 male adult sprinters (age/20.8±0.9 yrs, 100 m sprint time/11.20±0.33 sec). Axial images of the thigh muscle were taken by magnetic resonance imaging (MRI) at upper (70%) and middle (50%) position in femur. From these images, cross-sectional areas (CSA) of the quadriceps femoris, the hamstring and the adductor muscles were measured. The results of the regression analysis showed significant correlations between 100 m sprint time and both CSA of adductor and hamstring muscles at 70% position (r=-0.72 and r=-0.67, respectively). There were no significant correlations between 100 m sprint time and CSA of adductor or hamstring muscles at 50% position, and neither quadriceps femoris mudcles at 70 nor 50% positions. These results suggest that greater muscle volume of hamstring and adductor at upper position affect sprinting performance.

This study evaluated the exercise profile (heart rate, cycling speed and pedal cadence) during 25-30 km cycling and fitness and health level for adults (11 males: 69.6 ± 4.7 yrs; 6 females: 66.3 ± 4.9 yrs) with a recreational cycling habit (27.6 ± 14.8 km/week). Exercise intensity at a constant speed on a flat road during male and female cycling was 71.2 ± 11.5 and 66.8 ± 11.4% heart rate reserved (HRR), respectively. Exercise intensity over 60% HRR occupied 72% of cycling time. Peak intensity during male and female cycling was 89.2 ± 8.9 and 93.1 ± 6.1% HRR, respectively. VO2max and CS (chair stand)-30 test for male and female were 40.3 ± 4.3 and 37.7 ± 2.4 ml/kg/min, and 30.8 ± 3.1 and 30.1 ± 3.2 times, respectively. The muscle cross-sectional area of thigh extensor and flexor measured by MRI were 55.4 ± 6.5 and 58.3 ± 13.3 cm2 for male, and 45.5 ± 6.4 and 50.2 ± 5.7 cm2 for female, respectively. Blood profile for HDL-C (cholesterol), LDL-C and HbA1c (JDS) for male and female were 65.9 ± 8.2 and 67.9 ± 10.6 mg/dl, 112.3 ± 32.0 and 130.6 ± 12.3 mg/dl, and 4.8 ± 0.4 and 4.7 ± 0.1%, respectively. Fitness level and blood profile results were superior to those of the same aged adults. We concluded that the exercise intensity of cycling by middle and older adults with a recreational cycling habit is high and their fitness and health level are higher than average adults.
