![]() ![]() The results showed that the experimental group took significantly less time to complete the test. The control group listened to no music, while the experimental group listened to upbeat music. In a study conducted by Atkison, Wilson, and Eubank, participants completed a 10 km cycling time trial. This is because musical rhythm produces a synchronous effect in physical activities with cyclical movements (running, cycling, cross-country skiing, rowing, and others) due to the synchronization of bodily movement to the beats. ![]() ![]() It has been shown that music can be a useful tool that provides various benefits, including decreased perception of fatigue, improved emotional regulation, the generation of adaptations at the cardiovascular and hormonal level, and improved aerobic and anaerobic exercise performance. SF can be modified by sound stimuli and using music. Being able to achieve and maintain a higher-than-preferred stride frequency makes it possible to reduce lower limb loading variables, as well as the risk of reducing tibial stress fracture. Changes are also observed at the ankle joint with a more plantar flexed position, and there is more knee flexion and less peak knee flexion. In turn, there is less peak hip flexion and adduction when the loading response occurs. On the other hand, the knee, ankle, and hip joints absorb less mechanical energy as the impact of the lower limbs against the ground is less. It has been shown that at the same speed, at a faster SF, the metatarsal is supported, while, during a slower SF, the forefoot and rearfoot are supported, increasing the risk of injury. To favor the runner’s performance, the increase has to be 10% more in SF. Much research has shown that an increase in stride frequency (SF) can reduce the risk of injury for different reasons: on the one hand, knee flexion and plantar flexion increases in the stance phase as a consequence of resistive forces are reduced, the angular velocity of these joints increases, and hip stabilization during running is improved. Running at a fixed speed can alter different aspects such as electromyography and kinetics. When runners are fatigued, the stride frequency is no longer similar to their OSF and an increase in metabolic cost takes place. It generally coincides with the one that runners choose that is considered as the preferred stride frequency (PSF). Stride frequency is commonly used to refer to the total number of running steps per minute, and the optimal stride frequency (OSF) is the one that coincides with the frequency that minimizes metabolic cost. Moreover, this risk increases if there is an angulation of the ankle and knee joints in the stance phase caused by excessive or insufficient pronation or supination that alters the kinetic chain. However, a correct support during running is essential to absorb the contact with the ground, thus avoiding the risk of injuries and preventing them. Sports injuries can be caused by multiple factors. The 46.3% of recreational middle- and long-distance runners have suffered from injuries during one year of follow-up. The number of participants in popular races has increased in the last decade, with most of these participants being amateur. Future research is needed to confirm these results by enlarging the sample and carrying out an exhaustive biomechanical study. Future research should study the evolution of the improvement obtained in time as it is unknown if the increase in stride rate has been integrated in the runner’s technique, making the improvement obtained permanent. These results show that training with music feedback helps to improve stride frequency in recreational runners. No significant changes were observed in the stride frequency of the control group. Significant increases were found in the evolution of stride frequency in the experimental group between the pre- and post-test ( p = 0.002). For this purpose, the effect of a 6 week continuous running training program with the help of a musical track with a constant rhythm that was 10% higher than the preferred stride frequency of the subjects was analyzed and compared to a control group that performed the continuous running training without sound stimuli. The aim of this research was to check if a continuous running training program with a musical base improves the stride frequency of popular runners. In addition, it has been observed that there is a high percentage of injuries among them, and some of these injuries may be related to a low stride frequency. The number of participants in popular races has increased in recent years, with most of them being amateurs. ![]()
