“…The muscular changes depend on mechanotransduction, which is the ability of the cell to sense, process, and respond to mechanical stimuli, regulating the muscle mass 30 . The muscular plasticity can affect the flexibility and the strength capacity 31 . Cação-Benedini et al 29 ) investigated the effects of a single stretching session applied to the immobilized soleus muscle of young rats, and found an increase in the concentration of type III collagen, which remained for three days.…”

“…The dynamometer passively dorsiflexed the ankle joint at an angular velocity of 5 deg/s until the passive torque reached pre-determined torque value (around 15% PF MVC for each participant in familiarization session), being similar to the procedures of previous studies [5,11,16,21]. The passive DF ROM was calculated as the ROM attained from 0 deg (neutral) to the dorsiflexion angle.…”

“…However, many studies have shown that stretching training increases flexibility of the ankle joint [5,[11][12][13], although one study failed to improve active DF ROM after a 6-week static stretching regimen [4]. From the reports of Alter [14] and Kawakami et al [15], active DF ROM requires force development of the dorsiflexor muscles as well as the extensibility of the plantar flexor muscles.…”

The purpose of the present study was to clarify the combined effects of stretching and resistance training on the active and passive dorsiflexion range of motion of ankle joint. Sixteen young adult men were randomly assigned to a training ( = 8) or a control ( = 8) group. The training group trained one leg for the combined program of static calf stretching and dorsiflexors resistance training program (STR+TR) and the other leg for static stretching program only (STR). The training group executed stretching of both legs every day and resistance training every other day for six weeks. After the training program, in STR+TR side, both active and passive dorsiflexion range of motions significantly ( < 0.05) increased and also isometric maximal voluntary dorsiflexion torque increased, while in STR side, only passive dorsiflexion range of motion increased. In passive dorsiflexion range of motion, increased dorsiflexion ROM was accompanied by increased tendon elongation not muscle elongation. In conclusion, the combined program of stretching for calf muscles and resistance training for dorsiflexors increases active as well as passive dorsiflexion range of motion, while static calf stretching program is effective only for the increase in passive dorsiflexion range of motion.

“…Strengthening exercises-when done properly and through the full range of motions-conversely increase flexibility and can delay some of the loss of flexibility that occurs due to the aging process. 5,6 At the cellular level, a progressive decline in mitochondrial function with aging results in accumulation of the reactive oxygen species (ROS), generated by the addition of a single electron to the oxygen molecule. 7 ROS accumulation results in oxidative stress that can damage cellular components, such as skeletal muscle, lipids, proteins and DNA.…”

Background/Purpose: Flexibility is one of the components of physical fitness as well as muscle strength that decrease with age. Flexibility has been identified as one of the primary etiologic factors in preventive treatment of musculotendinous strains, and may be triggered by oxidative stress. We investigated whether changes in the oxidative stress marker, malondialdehyde-modified low density lipoprotein (MDA-LDL), is associated with change in trunk flexibility, which is a useful indicator of physical fitness, by a 12-week exercise administered to Japanese community-dwelling persons. Methods: The present study included 62 women aged 67 ± 7 years from a rural village. Nordic walking exercise of 120 min per week was performed for 12 weeks. Twelve-week changes in the various factors were calculated by subtracting the baseline values from the 12-week values. Results: Changes in sit-and-reach increased progressively with decreased changes in the MDA-LDL after the 12-week walking exercise (r=-0.312 p=0.014). Multiple linear regression analysis showed that change in the MDA-LDL (β=-0.284, p=0.021) as well as change in waist circumference (β=-0.258, p=0.036) was significantly and independently associated with change in sit-and-reach. When the data were further stratified by age, change in the MDA-LDL was significantly associated with change in sit-and-reach in women aged of ≤70 years. Conclusions: These results suggest that decreased change in MDA-LDL is a confounding factor for sit-and-reach after a 12-week NW exercise in community-dwelling women.
