Brief Summary

This study aims to apply a novel study methodology using high density electromyography (HDEMG) to know what are the mechanisms underlying the structural and functional changes obtained by two different training methods, commonly used, facilitating their understanding, study and subsequent application according to specific needs.

Conditions

Neuromuscular Adaptations

Keywords

Strength training; Neuromuscular adaptation

Outcome Measures

Primary Outcomes (1)

• Change from Baseline Mean Discharge Rate of Brachialis Biceps Motor Units at 4 weeks

  The mean discharge rate of the Brachialis Biceps motor units will be evaluated using a high density electromyography device (HDEMG). For this, the signal produced during isometric contractions at different submaximal force levels (10, 30, 50, and 70%) will be recorded, using an external analog to digital signal converter Sessantaquattro (64-channel EMG amplifier; OT Bioelettronica, Turin, Italy).

  Baseline and post-intervention (4 weeks after baseline)

Secondary Outcomes (5)

• Speed of propagation of Brachialis Biceps Motor Units

  Baseline and post-intervention (4 weeks after baseline)

• Isometric force of Brachialis Biceps using hand dynamometer

  Baseline and post-intervention (4 weeks after baseline)

• Isometric force of Brachialis Biceps using s-beam load cell

  Baseline and post-intervention (4 weeks after baseline)

• Muscle thickness (thickness) of the brachial biceps using ultrasound

  Baseline and post-intervention (4 weeks after baseline)

• Arm circumference

  Baseline and post-intervention (4 weeks after baseline)

Study Arms (2)

Speed Loss 20% Group

EXPERIMENTAL

The SL20% group will carry out a program based on the limitation of the speed loss, allowing to perform the exercise only until a speed loss of 20% is achieved, following a similar methodology previously published (Pareja-Blanco et al., 2017). The program will consist of a job for 4 weeks, with a frequency of 2 sessions a week. In each session, a 6-series routine with an open number of repetitions will be carried out twice, allowing as many repetitions as possible to perform until a 20% loss of execution speed is reached. The intensity of work will be 70% 1RM, resting 4 minutes between sets. As an only exercise, an elbow flexion (bicep curl) with dumbbell will be performed.

Other: Speed Loss 20% Strength Training

Reduced Rest Time Group

EXPERIMENTAL

The RRT group will carry out a program based on the reduction of rest time between series, following a previously published methodology (Stragier et al., 2019). The program will consist of a job for 4 weeks, with a frequency of 2 sessions a week. In each session, a 5 series routine with progressive repetition volume (3 to 7) at 70% 1RM will be performed twice, resting 15 seconds between sets and 150 seconds between each of the 2 blocks. The exercise to be performed will be an elbow flexion (bicep curl) with dumbbell.

Other: Reduced Rest Time Strength Training

Interventions

Speed Loss 20% Strength Training OTHER

Strength training based on the control of speed loss in execution.

Speed Loss 20% Group

Reduced Rest Time Strength Training OTHER

Strength training based on a protocol that includes reduced rest times between sets.

Eligibility Criteria

• Age: 18 Years - 35 Years
• Gender Eligibility Details: Recruitment will be done only among men because of the need to use a homogeneous sample due to the heterogeneity of the test itself. Previous studies have shown a greater possibility of data analysis in men when using HDEMG.
• Healthy Volunteers: Yes
• Age Groups: Adult (18-64)

You may qualify if:

• years
• men

You may not qualify if:

• physical exercise that involves work of upper limbs during the time of the intervention
• upper limb injury during the previous 12 months
• systemic diseases
