Can resistance training increases muscle oxidative capacity and capillary number?

 As written in the previous articles, Endurance training increases oxidative capacity (Increases in mitochondrial number) and the antioxidant capacity in the exercised muscle fibers. Endurance training also promotes the formation of new capillaries and therefore increases in muscle capillarization and exchange of gases. But we have got a question from one of my colleague

Does resistance training also promotes these changes in the trained muscle?

To answer this question is "Unclear", while some studies shows 'resistance training reduces mitochondrial content in the muscle', whereas some other studies shows 'no change in muscle oxidative capacity' and still other investigation conclude that 'resistance training can promote small increases in muscle oxidative capacity'. And all these findings are similar for capillarization also.

what is the explanation for these divergent results?

we can say numerous factors for these findings which includes frequency of training, the duration of training, number of repetitions performed during training and so on.

So, what will be the relevant exercise prescription to promote these changes through resistance training?

Number of studies incorporated long duration resistance training programs and high frequencies of training (3 days per week) and high volume (product of reps*sets*resistance) of exercise reported small improvements in muscle oxidative capacity and increases number of capillaries is dependent upon the frequency and volume of the training programs.

* Muscle oxidative capacity( amount of oxygen consumed per gram of muscle)

*Capillaries ( A tiny blood vessels connecting artery and vein, where exchange of gases occurs. These blood vessels carry oxygen and nutrients to individual cells throughout the body


In the bottom line,

The exact explanation for this question is unclear because of the numerous factors plays in these divergent findings. If you want to increase muscle oxidative capacity and capillary numbers then incorporate high frequency resistance training with high volume based on your periodization of training and individual goal. consult with your exercise professional and physician before modifying the intensity of your training program.

An alcohol consumption affects training performance - Here's how?

Alcohol is not an essential part of the human diet but various alcohols of which the only one quantitative significance of ethanol are consumed by larger part of the world's population. And also alcohol is significant source of energy 7 kilo calories (29 Kilo Joule) per gram of alcohol (Ethanol). Intake of alcohol may impair performance of endurance training. There is some groups of evidence supported that athletes consume more alcohols than non-athletes.    Ethanol on an impaired glycogen metabolism: Re synthesis of glycogen stores in liver and muscle is one of the key goals of athletes after intensive training or competition. Most of the evidence shoes that synthesis of of glycogen is impaired by impaired hepatic glucose output in the presence of even relatively low levels of ethanol. At the same time there seems to be no effect on type 2 muscle fibers. The reduced hepatic glucose output will result in less insulin secretion and thereby ethanol affects the glucose release an...

Facts about "Detraining"- Meta-analysis

Are you a Fitness Enthusiast?, Then you may familiar with the term "Detraining". Sometimes you may have a question, 'What happens next if i 'Quit' my training?' . Here we are coming up with a relevant information for the question. Like how your body adapts to the training and changes occurs such as change in body composition, changes in physiological, Hematological & Metabolic activities, Reversing of all these training adaptations can occur if you quit your training. Let's see deeper into this topic, What is Detraining (AKA, Reversibility Principle of Training): It is a process, in which your training adaptations will start decline, It occurs when person quits his or her training program. Partial or complete loss of training adaptations as a result of a training reduction or cessation. It occurs due to lack of compliance with an exercise program, Injury, Illness (or) a planned periodization transition phase. ( Note: All Physiological variables don...
