Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
In clinical practice, it is often difficult and contraindicated to use near-maximal loads (e.g., in the early stages of cardiac rehabilitation, after sport injury, etc.). Muscle atrophy and weakness often occur rapidly in the affected area due to the effects of trauma (or disease) and inactivity. Consequently, training modalities that promote hypertrophy or counteract atrophy without the use of heavy loads should be of special interest in the rehabilitation of some chronic diseases for which high musculoskeletal forces are contraindicated.
Occlusive strength training with tourniquet cuffs was first used nearly twenty years ago. Studies have shown that low to-moderate intensity (20-50% of 1RM) resistance training with vascular occlusion leads to gains in muscle strength and volume comparable to those seen after conventional heavy resistance training. This effects suggest, that ischemic strength training may be a useful method in rehabilitation and other contexts.
To conclude, the aim of this study is to compare the effect of low intensity resistance training with vascular occlusion vs. normal physical activity on:
1. muscle hypertrophy, strength and neuromuscular parameters;
2. vascular function;
3. and blood parameters (anabolic and catabolic hormones, catecholamines, inflammations factors, parameters of oxidative stress etc.)

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Resistance training group
Patients to be randomly assigned to the "resistance training group" will have resistance training with vascular occlusion 2 times per week for a period of 8 weeks on unilateral leg extension machine. During each training, they will performed 3 sets of 15 repetitions at the intensity of 30% 1 RM (repetition maximum). Each training set will separated by a 30 second rest period.
Resistance training with vascular occlusion
Patients will perform unilateral leg extension resistance training with vascular occlusion 2 times per week for a period of 8 weeks. Each training session will consist of 3 sets of 15 repetitions at the intensity of 30% 1 RM with 30 s of rest period between sets.
Control group
Patients to be randomly assigned to the control group (normal physical activity) will continue with their usual physical activity regime.
No interventions assigned to this group
