A guide to determining sets, reps and rest periods for the strength training beginner from the files of the Explosivelyfit Strength Training Gym

A guide to determining sets, reps and rest periods for the strength training beginner 

Hypertrophy of the muscle fibers.

The recommendations here are non specific as to sarcoplasmic or myofibril hypertrophy. However, if you want to add strength to your muscles instead of just cosmetic size then stay on the shorter end of the rep ranges for this training cycle.

Due three to four sets of ten to twelve repetitions and rest between each set for approximately one minute. A shorter rest will be more along the lines of the bodybuilding programs, i.e. a 1:1 work to rest ratio. Whereas the longer one will help the muscles recover so more weight can be used thereby increasing the strength and size of the fibers and not the fluids in and around the cells.

For the strength and power training stick with four to five sets of three to five reps with longer rest periods between each set. The rest times during this training phase will be between three and four minutes. This allows the muscles to recover nearly 100% so they can continue putting out the effort necessary to push the weights the next set.

The strength sessions involve three to four sets of between six to eight repetitions with shorter rest periods than the strength and power cycle. Rest for pure strength is between two to three minutes.

A person starting out on a strength program will realize in a short time that these suggestions are the pathways to success.

Sport and lifestyle activity-range of motion exercising from the files of the Explosivelyfit Strength Training Gym

Sport and lifestyle activity-range of motion exercising

Your joints and muscles are meant to function within standardized degrees of movement, commonly referred to as the range of motion (ROM). The stronger you are within these ranges, the better protected you will be in preventing injuries from occurring. Therefore when doing your exercise routine keep in mind the following two guidelines:

1. You gain the most strength within the range of motion (ROM) at which you exercise.

2. The smaller the range of motion you in the joint, the less will be the carry over strength throughout the rest of the movement.

The basis of every quality strength training or fitness program relies, in part, on these two premises. As an example, let’s look at the squat while explaining these principles.

Many lifters do short range squats, known as high squats, in the gym. They get into a machine or in rare cases under a bar and drop down a few inches and call it good. In many instances this isn’t even to a parallel position, let alone below parallel where they should be before starting back up again. Depending on the load of the bar or on the machine, strength may be increased within this small range of motion but its unlikely this will happen.

This range of movement is too little and does not support normal living activities such as sitting down in a chair and then getting back up. If the strength is not developed within a range that is vital to living an active lifestyle then it is not useful. This group of fitness enthusiasts would be better served by going deeper in their squats, thereby getting a transfer of useable strength into their daily lives. This naturally leads in to the second principle.

An individual or strength athlete will become stronger when training the full range of motion. This expands the strength curve and transfers more useable muscle activity across greater degrees of the joint angle. Greater degree angles of strength protect the joint from injury, especially at the far ranges of motion.

The take home message is don’t cut yourself short with limited range of motion exercises.

Motor unit recruitment 09038

Sunday, March 9th, 2008

 

Motor unit recruitment

 The size principle states that slow fatigue resistant motor units are recruited first. This theory serves to demonstrate the relationship between the motor unit twitch force and the recruitment threshold of the fibers.  For example these first muscle fibers are not able to sustain a lasting power output and give out rapidly. They do not have the ability to produce great force. Thus after lifting a certain number of repetitions the original fibers are fatigued and not producing the necessary force to continue. New fibers are then called upon to lift the weight. These new fibers are faster and much more powerful but also fatigue much quicker than the original fibers. These soon become exhausted and of limited use in the lifting process. But the advantage of this recruitment process is the majority of the muscles’ fibers have contributed all they can to the lift.  In other words the fibers have all been exhausted and will have to repair the damage caused by the lift in order to become stronger and better able to tolerate the resistance. The next time this load is placed upon them, they will have accommodated and grown stronger.  

Training hint:

 

Training in such a manner as to inhibit the weaker fibers and going straight to the fast acting powerful ones is the key to instant and explosive force and power. Conditioning the CNS to bypass the non-power fibers occurs in some of the elite strength athletes. This takes the body a long time to make this adaptation and requires a deep dedication to the strength sport-more so than many people have at the lower levels of participation.
