TLDR
Full understanding of these physiological processes will provide the physiological basis for understanding of tissue overloading and injury seen in both tendons and muscle with repetitive work and leisure time physical activity. Expand
Muscle and blood metabolites during a soccer game: implications for sprint performance.
TLDR
Sprint performance is reduced both temporarily during a game and at the end of a soccer game, the latter finding may be explained by low glycogen levels in individual muscle fibers. Expand
Load‐displacement properties of the human triceps surae aponeurosis in vivo
TLDR
The stiffness and Young's modulus exceeded those previously reported for the tibialis anterior tendon in vivo, but were similar to those obtained for various isolated mammalian and human tendons. Expand
Biomechanical Responses to Repeated Stretches in Human Hamstring Muscle In Vivo
TLDR
The data show that the method employed is a useful tool for measuring biomechanical variables during a stretch maneuver and may provide a more detailed method to examine skeletal muscle flexibility. Expand
Region specific patellar tendon hypertrophy in humans following resistance training
Aim:  To examine if cross‐sectional area (CSA) differs along the length of the human patellar tendon (PT), and if there is PT hypertrophy in response to resistance training.
Differential strain patterns of the human gastrocnemius aponeurosis and free tendon, in vivo.
TLDR
The free Achilles tendon demonstrates greater strain compared with that of the distal (deep) aponeurosis during voluntary isometric contraction, which suggests that separate functional roles may exist during in vivo force transmission. Expand
Changes in muscle size and MHC composition in response to resistance exercise with heavy and light loading intensity.
TLDR
LL resistance training was sufficient to induce a small but significant muscle hypertrophy in healthy young men, however, LL resistanceTraining was inferior to HL training in evoking adaptive changes in muscle size and contractile strength and was insufficient to induce changes in MHC composition. Expand
Training-induced changes in muscle CSA, muscle strength, EMG, and rate of force development in elderly subjects after long-term unilateral disuse.
TLDR
In contrast to traditional physiotherapy and electrical stimulation, strength training increased muscle mass, maximal isometric strength, RFD, and muscle activation in elderly men and women recovering from long-term muscle disuse and subsequent hip surgery. Expand
Coordinated collagen and muscle protein synthesis in human patella tendon and quadriceps muscle after exercise
TLDR
There is a rapid increase in collagen synthesis after strenuous exercise in human tendon and muscle, and the similar time course of changes of protein synthetic rates in different cell types supports the idea of coordinated musculotendinous adaptation. Expand
Muscle performance during maximal isometric and dynamic contractions is influenced by the stiffness of the tendinous structures.
TLDR
Data indicate that muscle output in high-force isometric and dynamic muscle actions is positively related to the stiffness of the tendinous structures, possibly by means of a more effective force transmission from the contractile elements to the bone. Expand
