Theory of vibrational impact and application in Samson-fit ProV and Sport design

2. Physical basis of vibrational impact

2.1 Vibration signal parameters

Vibration as a physical factor is characterized by the following parameters:

2.2 Biological resonance

The key mechanism of vibration action is biological resonance — matching the frequency of external vibrational impact with the natural oscillation frequency of biological structures. Each tissue has its own resonant frequency:

• Muscle fibers — 20–50 Hz
• Blood vessels — 5–20 Hz
• Bone tissue — 100–200 Hz
• Nerve fibers — 50–150 Hz

When frequencies match, the effect is amplified many times. This is why the choice of vibration frequency is a critically important parameter for targeted impact.

2.3 Frequency ranges and their effects

3. Mechanisms of BMS action

3.1 Neuromuscular activation

Vibration at 20–60 Hz causes tonic vibration reflex (TVR) — involuntary muscle contraction in response to vibrational stimulation of muscle spindles. Mechanism:

1. Vibration activates muscle spindles (Ia-afferents)
2. Signal enters the spinal cord via dorsal roots
3. Alpha-motoneurons receive excitation → muscle fibers contract
4. Simultaneously, gamma-motoneurons of antagonists are inhibited (reciprocal inhibition)

Result: up to 97 % of muscle fibers are involved in contraction (versus 40–60% with voluntary effort). This is the key advantage of BMS over regular training.

3.2 Vascular-lymphatic peripheral hearts

V.T. Nazarov introduced the concept of peripheral hearts — rhythmically contracting muscle groups working as pumps. With BMS:

• Vibrational muscle contractions create a musculo-venous pump
• Venous return increases by 30–50%
• Lymphatic drainage accelerates 2–4 times
• Capillary microcirculation improves by 40–60%

For people with impaired venous and lymphatic drainage, this is especially valuable — vibration replaces the missing pump.

3.3 Psychophysiological effects

BMS causes pronounced psychophysiological shifts:

• Endorphin release: vibration stimulates beta-endorphins, which reduces pain syndrome and elevates mood
• Cortisol reduction: moderate vibration reduces stress hormone levels
• Improved sleep: due to normalization of nervous processes
• Increased performance: improvement of neuromuscular coordination

3.4 Adaptation and hormonal mechanisms

Systematic BMS application triggers a cascade of adaptive reactions:

1. Acute adaptation (single session): activation of blood circulation, lymphatic drainage, pain relief
2. Delayed adaptation (2–4 weeks): increased muscle strength and endurance, improved bone mineralization
3. Cumulative adaptation (1–3 months): hormonal restructuring, increased muscle mass, stabilization of metabolism

It is the cumulative adaptation that provides the long-term therapeutic and preventive effect of BMS.

4. Practical application of BMS

4.1 Strength development

According to V.T. Nazarov, BMS application in training gives the following strength gains:

4.2 Flexibility

BMS allows overcoming reflexive muscle resistance during stretching. Vibration relaxes antagonists and reduces tone, increasing range of motion by 15–30% over 4 weeks of training.

4.3 Recovery

After intense training, BMS accelerates recovery:

• Lactate clearance acceleration — 25–40% faster
• CK (creatine phosphokinase) level reduction — by 20–35%
• Reduction of muscle pain (DOMS) — by 30–50%

4.4 Rehabilitation

BMS is effectively used in rehabilitation:

• Recovery after musculoskeletal injuries
• Rehabilitation for neurological diseases (paresis, paralysis)
• Prevention and treatment of osteoporosis
• Restoration of blood circulation in vascular disorders

4.5 Professional sports

BMS is used in training national team athletes in:

• Track and field
• Weightlifting and powerlifting
• Wrestling and martial arts
• Hockey
• Football

5. Hormonal and biochemical effects

5.1 Testosterone

Vibrational impact increases testosterone levels by 10–20% with regular training. Mechanism: vibration stimulates testicular Leydig cells through enhanced blood supply and neuroreflex pathways.

5.2 Growth hormone (GH)

The level of somatotropic hormone increases by 15–30% with vibration training. This is associated with activation of the hypothalamic-pituitary axis and enhanced growth hormone release from the anterior pituitary.

5.3 Endorphins

BMS triggers the release of beta-endorphins — endogenous opioid peptides. This explains the analgesic effect of vibration and mood elevation after sessions.

5.4 Cortisol

Moderate vibration reduces cortisol levels by 10–15%, while excessive vibration increases it. This underscores the importance of dosing vibrational exposure.

5.5 Insulin-like growth factor (IGF-1)

IGF-1 levels increase by 15–25% with systematic vibration training. IGF-1 is a key mediator of anabolic processes, stimulating muscle tissue growth and recovery of damaged fibers.

6. Vibration application in Samson-fit ProV design

6.1 Vibro-grip

The vibro-grip is a key element of the Samson-fit ProV and Samson-fit Sport trainers, generating mechanical oscillations in the physiological range and implementing the BMS principle by V.T. Nazarov. Vibration is transmitted through the grip to the muscles of the hands, forearms, shoulder girdle and further along muscle chains, activating proprioceptors along the entire path of effort. The vibro-grip and vibration handles are installed on both the ProV model (with dynamometer) and the Sport model (without dynamometer, converter and monitor).

6.2 Synergy with chain tension

The key innovation of Samson-fit ProV is combining isometric chain tension with vibrational impact. This creates a unique training effect:

• Isometric tension holds the muscle in a contracted state → slow fiber type is activated
• Vibration additionally engages fast muscle fibers via TVR → up to 97% of muscle fibers work
• Chain tension provides precise load dosing: in ProV — via dynamometer with monitor, in Sport — by subjective effort sensation
• Synergy of isometrics and vibration gives a strength increase 30–50% greater than isometrics without vibration

6.3 Comparison with other vibration devices

6.4 Safety

Safety of vibrational impact in Samson-fit ProV and Samson-fit Sport trainers is ensured by:

• Low amplitude (1–4 mm) — significantly below hazardous thresholds
• Controlled frequency — in the range recognized as safe (25–50 Hz)
• No vertical load on the spine
• Duration control — built-in timer automatically limits the session
• Adjustable intensity — smooth frequency adjustment in the 25–50 Hz range

6.5 Contraindications

Vibration training on Samson-fit ProV and Sport trainers is contraindicated for:

• Acute inflammatory processes
• Thrombophlebitis and severe varicose veins
• Malignant neoplasms
• Epilepsy
• Decompensated hypertensive disease
• Pregnancy
• Presence of a pacemaker
• Fresh fractures and joint injuries

7. Vibration disease

7.1 Conditions of occurrence

Vibration disease is an occupational disease caused by prolonged (years) exposure to industrial vibration of high amplitudes and accelerations. Conditions of development:

• Chronic exposure to vibration with acceleration exceeding 10g
• Prolonged exposure (hundreds of hours per year)
• Vibration is transmitted through tool handles or platform

Main symptoms: Raynauds syndrome (blanching of fingers), numbness, decreased sensitivity, microcirculation disorders.

7.2 Why Samson-fit ProV and Sport are safe

Samson-fit ProV and Samson-fit Sport do not create conditions for vibration disease:

• Acceleration does not exceed 3g — 3 times below the threshold of onset
• Session duration is limited to 10–15 minutes (versus 8 hours/day in industry)
• Frequencies 25–50 Hz are in the safe window between infrasound and ultrasound
• No vibration transmission to the entire body — impact is local
• Amplitude 1–3 mm is minimal compared to industrial vibration (5–20 mm)

8. Practical recommendations

8.1 Training modes

8.2 Safety rules

1. Start with minimum intensity and duration
2. Do not exceed total vibration exposure of 15 minutes per workout
3. Take a break between sets of at least 30 seconds
4. If discomfort, numbness or pain occurs, stop the session immediately
5. Do not use vibration during exacerbation of chronic diseases
6. Consult a doctor before starting vibration training
