“…Stiffness reductions have primarily been linked to the loss of muscle strength and neuromuscular function due to aging, both of which may be slowed down by running training ( 21 , 58 , 59 ). It has indeed been shown that (young) runners with a higher training volume can more efficiently coordinate the thigh muscles to regulate knee stiffness during landing ( 42 ), whereas older runners with a consistently high training volume can retain their stiffness regulation capacity ( 58 , 60 ). These findings support the notion that sufficiently high running volume might positively contribute to the maintenance of appropriate leg and joint stiffness in master runners and can help attenuate economy and performance loss with aging.…”

Master runners maintain a similar running economy to young runners, despite displaying biomechanical characteristics that are associated with a worse running economy. This apparent paradox may be explained by a greater physiological effort—i.e., percentage of maximal oxygen uptake (VO2-max)—that master runners perform at a given speed. Moreover, age-related responses to non-exhaustive sustained running are yet underexplored. The aims of this study were, therefore, to examine if biomechanical adjustments in master runners are physiological-effort dependent, and to explore the age-related biomechanical changes during a non-exhaustive sustained run. Young (23.9 ± 6; n = 12) and master (47.3 ± 6.9; n = 12) runners performed a sustained 30-minute treadmill run matched for relative physiological effort (70% VO2-max), while spatiotemporal and lower-limb kinematic characteristics were collected during the 1st and 30th minute. Group differences were observed in step/stride length, knee touch-down angle, and knee stiffness. However, both groups of runners had a similar step frequency, vertical center of mass oscillation, and knee range of motion. Age-related adjustment in these latter characteristics may thus not be an inevitable result of the aging process but rather a strategy to maintain running economy. The relative physiological effort of runners should, therefore, be considered when examining age-related adjustments in running biomechanics.

“…Peak vertical impact force, even though not significantly higher at M57, increased by an average of 21 %, compared to M50. To date, there is debate in the literature as to whether this vertical force increases, decreases, or does not significantly change with age (Power, Dalton, Behm, Vandervoort, Doherty & Rice, 2010;Kline & Williams, 2015;Diss, Weeks, Gittoes, Tong, & Kerwin, 2015;DeVita et al, 2016). However, these previous studies were based on cross sectional designs and the results are therefore confounded by inter-individual differences in and between, groups.…”

Biomechanical research exploring the age-based mechanics of running gait can provide valuable insight into the reported decline in master endurance running performance. However, few studies have shown consistent biomechanical differences in the gait of trained distance runners compared to their younger counterparts. It might be that differences occur in the interaction between joints. The aim was to explore the differences in in tri-joint synchrony of the lower limb, quantified through Cluster Phase analysis, of runners at 50 years of age compared to seven years later. Cluster Phase analysis was used to examine changes in synchrony between 3 joints of the lower limb during the stance phase of running. Ten male, endurance-trained athletes M50 (age = 53.54±2.56 years, mass = 71.05±7.92 kg) participated in the study and returned after seven years M57 (age = 60.49±2.56 years, mass = 69.08±8.23 kg). Lower limb kinematics (Vicon, 120 Hz) and ground reaction forces (Kistler, 1080 Hz) were collected as participants performed multiple trials at a horizontal running velocity = 3.83±0.40 m•s -1 over the force plate. Significant increase (31 %) in rate of force development in the absorption phase, and significantly reduced sagittal plane knee joint range of motion (30.50 v 23.68 o ) were found following the seven years of ageing. No further discrete single joint measures were significantly different between M50 and M57. Joint synchrony between the hip, knee and ankle was significantly higher at M57 compared to M50 during the absorption phase of stance. The force attenuation strategy is compromised after seven years of ageing, which is associated with more synchronous movements in the lower limb joints. Increased joint synchrony as a function of age could be a mechanism associated with this key injury provoking phase of running gait.
