Muscle metabolism and performance improvement after two training programmes of sprint running differing in rest interval duration
Ploutarchos Saraslanidis,Anatoli Petridou,Gregory C. Bogdanis,Nikiforos Galanis,George Tsalis,Spiros Kellis,Vassilis Mougios +6 more
TL;DR: Compared the effects of two training programmes, differing in rest interval duration, on muscle (vastus lateralis) metabolism and sprint performance, training with a limited number of repeated short sprints (≤10 s) may be more effective in improving speed maintenance in 200- and 300-m runs when performed with a 1:1 rather than a1:6 exercise-to-rest ratio.

Increased intrinsic mitochondrial function in humans with mitochondrial haplogroup H.
TL;DR: In skeletal muscle from men with mitochondrial haplogroup H, an increased intrinsic mitochondrial function is present, and there was no relationship between haplogroups and VO2max.

Manish S. Bharadwaj,Daniel J. Tyrrell,Mary F. Lyles,Jamehl L. Demons,George W. Rogers,Anthony J.A. Molina +5 more
TL;DR: A method for obtaining samples of human Vastus lateralis, isolating mitochondria from minimal amounts of skeletal muscle tissue, and plate based respirometric profiling using an extracellular flux (XF) analyzer is described.

Adding strength to endurance training does not enhance aerobic capacity in cyclists.
TL;DR: It is demonstrated that concurrent training does not enhance muscle aerobic capacity and endurance performance in cyclists.

Acute and chronic exercise in patients with heart failure with reduced ejection fraction: evidence of structural and functional plasticity and intact angiogenic signalling in skeletal muscle
TL;DR: Structural/functional plasticity and appropriate angiogenic signalling were observed in skeletal muscle of patients with HFrEF, and VEGF did not respond to acute exercise, capillarity was augmented.

Diet, Muscle Glycogen and Physical Performance
TL;DR: It has been shown that the glycogen content and, consequently, the long-term work capacity can be appreciably varied by instituting different diets after glycogen depletion.

Glycogen, glycolytic intermediates and high-energy phosphates determined in biopsy samples of musculus quadriceps femoris of man at rest. Methods and variance of values.
TL;DR: Variation in muscle content of ATP, ATP + ADP + AMP, phosphorylcreatine (PC), creatine (Cr), PC + Cr, and glycogen, between legs, between sites on the same muscle, or as a result of error introduced during analysis, was small compared with the between-individuals variance.

TL;DR: Goldstein1 has shown that a humoral factor, which decreases the blood glucose concentration, is released during exercise and it is known that the insulin requirement decreases in diabetic subjects during exercise.
