SummarySeven healthy male subjects were studied under control conditions and following 5–6 months of heavy resistance training and 5–6 weeks of immobilization in elbow casts. Cross-sectional fibre areas and nuclei-to-fibre ratios were calculated from cryostat sections of needle biopsies taken from triceps brachii. Training resulted in a 98% increase in maximal elbow extension strength as measured by a Cybex dynamometer, while immobilization resulted in a 41% decrease in strength. Both fast… Expand
Muscle performance, morphology and metabolic capacity during strength training and detraining: A one leg model
TLDR
The significant alterations in peak torque outputs with both legs suggest that neural adaptations play a prominent role in strength performance with training and detraining. Expand
Effect of training with different intensities and volumes on muscle fibre enzyme activity and cross sectional area in the m. triceps brachii
TLDR
When training intensity is sufficient to stimulate to increases in oxidative and glycolytic capacity, the SDH and α-GPDH response seems to be volume independent. Expand
HUMAN MUSCLE STRENGTH TRAINING: THE EFFECTS OF THREE DIFFERENT REGIMES AND THE NATURE OF THE RESULTANT CHANGES BY D. A. JONES
1. Increases in strength and size of the quadriceps muscle have been compared during 12 weeks of either isometric or dynamic strength training. 2. Isometric training of one leg resulted in aExpand
Low-volume muscular endurance and strength training during 3-week forearm immobilization was effective in preventing functional deterioration
TLDR
The training programs during immobilization period used in this experiment were effective in preventing a decline in muscle oxidative function, endurance and strength. Expand
Deficit in human muscle strength with cast immobilization: contribution of inorganic phosphate
TLDR
It is suggested that immobilization, independent of reloading, leads to a significant increase in the restingPi concentration of human skeletal muscle, and alterations in resting Pi concentration may contribute to strength deficits with immobilization not accounted for by changes in muscle CSA or neural adaptations.

Muscle hypertrophy and fast fiber type conversions in heavy resistance-trained women
TLDR
The heavy-resistance training resulted in significant hypertrophy of all three groups: I (15%), IIA (45%), and IIAB + IIB (57%). Expand
Effects of velocity of isokinetic training on strength, power, and quadriceps muscle fibre characteristics
TLDR
No significant changes were observed over the 10-week training period in percentages of type I, IIa and IIb fibres, but both groups showed significant increases in type I and IIa fibre areas. Expand
Neuromuscular adaptations in human muscle following low intensity resistance training with vascular occlusion
TLDR
It is concluded that low-intensity resistance training in combination with vascular occlusion produces an adequate stimulus for increasing muscle strength and causes changes in indices of neuromuscular function, such as depressed resting twitch torque and enhanced PAP. Expand
Functional properties of human muscle fibers after short-term resistance exercise training.
TLDR
At the level of the cross bridge, the effects of short-term resistance training were quantitative (fiber hypertrophy and proportional increases in fiber P(o) and absolute power) rather than qualitative (no change in P(O)/CSA, V(o), or power/fiber volume). Expand
Hypertrophy without increased isometric strength after weight training
TLDR
The data indicate that a moderate but significant amount of hypertrophy induced by weight training does not necessarily increase performance in an isometric strength task different from the training task but involving the same muscle group. Expand

Biochemical adaptation of human skeletal muscle to heavy resistance training and immobilization.
TLDR
It was concluded that heavy-resistance training results in increases in muscle energy reserves which may be reversed by a period of immobilization-induced disuse. Expand

TLDR
It was concluded that a high isometric muscular strength is well correlated with large cross-sectional area of white fibres, and the size of red fibres seems to be unrelated to isometric muscle strength as well as aerobic capacity. Expand
Functional and structural changes after disuse of human muscle.
TLDR
The discrepancy between the magnitude of the difference observed in the gross measurement of leg function (maximum oxygen uptake) and structure (leg volume) as compared with the cellular level (cross-sectional fibre area) is discussed. Expand
Human muscle fiber types in power lifters, distance runners and untrained subjects
TLDR
It is suggested that the fast-twitch fibers are mainly involved in the adaptation of muscle to exercise since the percentage of SO fibers varies greatly among individuals within and between the 3 groups studied. Expand

TLDR
The total number of muscle fibers of the right exercised FCR increased significantly when compared with that of the unexercised left FCR (p less than 0.05), found to be due to muscle fiber splitting. Expand

TLDR
Guinea pig hindlimbs were unilaterally immobilized at resting length to evaluate histochemical, biochemical, and contractile properties of immobilized muscle, and tetanic tension per gram wet muscle weight or 100 mg myofibrillar protein was significantly greater in the immobilized gastrocnemius.

TLDR
A histochemical study has been made of muscle biopsy material from 11 patients with injuries of the anterior cruciate ligament of the knee-joint, finding that eight of the cases, with clinical evidence of muscular atrophy, showed marked differences in size between the red and white muscle fibres.
