OBJECTIVES: To examine the possible influences of age and gender on muscle volume responses to strength training (ST). 
Alterations in Skeletal Muscle Strength and Mitochondrial Function Induced by Aging and Exercise
This review concludes that the current state of literature in Europe is likely to be worse than in previous reviews, and the need for further research is to be considered.
Sarcopenia, implications of physical exercise in its pathophysiology. prevention and treatment
Resumen en: Sarcopenia is known as a progressive muscle wasting produced as years accumulate and characterized by a progressive loss of muscle mass and strength, inc...
Effects of Exercise and Amino Acid Supplementation on Body Composition and Physical Function in Community‐Dwelling Elderly Japanese Sarcopenic Women: A Randomized Controlled Trial
To evaluate the effectiveness of exercise and amino acid supplementation in enhancing muscle mass and strength in community‐dwelling elderly sarcopenic women, a large number of women in this study are obese.
Effect of whey protein supplementation after resistance exercise on the muscle mass and physical function of healthy older women: A randomized controlled trial
A 24‐week program of nutritional supplementation using whey protein, ingested after resistance exercise, in increasing muscle mass and physical function among community‐dwelling healthy older Japanese women is evaluated.
Skeletal Muscle Hypertrophy After Aerobic Exercise Training
This work has demonstrated that aerobic exercise acutely and chronically alters protein metabolism and induces skeletal muscle hypertrophy and provides novel perspective on skeletal muscle mass regulation and insight into exercise countermeasures for populations prone to muscle loss.
Anabolic responses to resistance training in older men and women: a brief review.
Relatively small sample sizes in most of the interventions limited their ability to detect significant sex differences and should be considered when interpreting these studies, and future research should incorporate larger sample sizes with multiple measurement time points for anabolic responses.
Different training responses in elderly men and women following a prolonged muscle resistance training intervention
Resistance training is an effective strategy to counteract the age‐related loss of muscle mass and strength in elderly, but whether the benefits of training differ between sexes is unclear. A total
Resistance training induced increase in muscle fiber size in young and older men
After RT, muscle fiber size increased less in older compared to young men, and this was associated with lower protein and energy intake and increases in myostatin gene expression in older when compared toYoung men.
Similar muscle protein synthesis rates in young men and women: men aren't from Mars and women aren't from Venus.
men have more muscle than women, and several attempts have been made to determine the physiological mechanisms responsible for this phenomenon by measuring the rates of muscle protein synthesis (MPS)


Strength Training Normalizes Resting Blood Pressure in 65‐ to 73‐Year‐Old Men and Women with High Normal Blood Pressure
The objective was to determine the effects of heavy resistance strength training on resting blood pressure in older men and women and to establish a baseline for this study.
The Role of Habitual Physical Activity in Preserving Muscle Strength from Age 80 to 85 Years
Overall, those men and women who were considered to have maintained a high level of activity retained their strength at a higher level than the more sedentary participants.
Long-term resistance training in the elderly: effects on dynamic strength, exercise capacity, muscle, and bone.
It is concluded that long-term resistance training in older people is feasible and results in increases in dynamic muscle strength, muscle size, and functional capacity.
Effects of strength training on muscle hypertrophy and muscle cell disruption in older men.
The results indicate that middle-aged and older men can safely participate in a total body strength training program, intense enough to produce substantial increases in muscle strength and hypertrophy, without promoting muscle soreness or significant muscle cell disruption.

Age does not affect the muscle mass response to either ST or detraining, whereas gender does, as men increased their muscle volume about twice as much in response to ST as did women and experienced larger losses in responseto detraining than women.
Muscle quality. II. Effects Of strength training in 65- to 75-yr-old men and women.
Although older men appear to have a greater capacity for absolute strength and muscle mass gains than older women in response to ST, the relative contribution of neuromuscular and hypertrophic factors to the increase in strength appears to be similar between genders.
Effect of age on muscle hypertrophy induced by resistance training.
Age can attenuate the hypertrophic response of muscle groups to resistance training, when the training load is proportional to baseline strength, however, aging does not impair training-induced increases in specific tension.
Skeletal muscle adaptations during early phase of heavy-resistance training in men and women.
The data suggest that skeletal muscle adaptations that may contribute to strength gains of the lower extremity are similar for men and women during the early phase of resistance training and, with the exception of changes in the fast fiber type composition, that they occur gradually.
Changes in muscle morphology, electromyographic activity, and force production characteristics during progressive strength training in young and older men.
Both neural adaptations and the capacity of the skeletal muscle to undergo training-induced hypertrophy even in older people explain the gains observed in maximal force in older men, while rapid force production capacity recorded during the isometric knee extension action remained unaltered during the present mixed strength training program.
Age and gender comparisons of muscle strength in 654 women and men aged 20-93 yr.
Both men and women experience age-related losses in isometric, Con, and Ecc knee extensors peak torque; however, age accounted for less of the variance in Ecc peak torque in women, and women tend to better preserve muscle quality with age for Eccpeak torque.
