Isotonic and Isokinetic Training Effect on Vertical Jump Performance (51 pp.) Director: Dr. Kathleen Mille The purpose of the study was to compare isotonic and isokinetic weight training and their effect on leg power in women basketball players. A modification of the vertical jump and reach test was the instrument chosen to measure the verticalAuthor: Sarah D.
Novak. The general purpose of this study was to compare the efficacy of two weight training methods: isotonic and isokinetic. The sixty-two college students who were the subjects were randomly assigned to the isotonic group or the isokinetic group.
There were thirty subjects in the isotonic group 2nd thirty-two subjects in the isokinetic : Don W. Brubacher. ments in strength and vertical jumping ability. The isokinetic concept of strength training appears to hold the most promise in vertical jump training.
Because it provides maximum resistance with constant speed throughout an entire range of motion, isokinetics may prove superior to more traditional training.
There is controversy on whether isokinetic or isotonic training produce more functional gains in strength (Wilson and Murphy, ). Studies (Helling,Smith and Melton, ) compared isokinetic training to isotonic training effects on vertical jump by: 5.
Controversy still exists regarding the use of isokinetic and isotonic exercise in rehabilitation. Many authors have compared these two types of training methods on various strength measures and. Objective: To compare muscle strength, mass, and functional performance in response to isometric, isotonic, and isokinetic contractions, when training loads (volume and intensity) are equated.
Muscular strength is the force that a muscle or muscle group can exert against a resistance in one maximal effort. There are four types of muscular contraction: isotonic, isometric, eccentric and isokinetic.
With isotonic contractions (muscle shortening while lifting a constant load), the tension developed the range of motion is related to (1) the length [ ]. Isokinetic Exercise Benefits. Before we start comparing isokinetic vs isotonic exercises we should begin by explaining what each of those are and how they affect our body and muscles.
What is Isokinetic Exercise. One of the types of exercises when training for strength is an isokinetic Exercise. It utilizes a special machine that keeps a constant speed regardless of how much effort.
Start studying Isometric isotonic and isokinetic. Learn vocabulary, terms, and more with flashcards, games, and other study tools. Search. Resistance exercise in which concentric and eccentric exercises are performed against a constant weight.
Isotonic testing strength. Strength training was conducted three days per week, 40 minutes per day for eight weeks. The results demonstrated a clear superiority of the isokinetic training procedures over the isotonic procedures relative to strength, anthropometric, measures and motor performance tasks.
The three training groups exhibited similar changes in body composition. Isotonic Isokinetic Isometric Isokinetic, Isometric, & Isotonic What they are Isometric An isometric exercise is a type of strength training in which muscle length and the joint angle do not change.
They are done in static positions rather than being dynamic with a large range of. The purposes of this investigation were to determine: 1) which form of closed kinetic chain training, isokinetic or isotonic, would produce the greatest increase in one-legged jump reaction force, and 2) which training method most accurately predicts peak force produced during a one-legged jump.
Most exercise involves isotonic muscle contractions, which cause shortening and lengthening with movement. Isometric and isokinetic exercises are less common. An isotonic contraction is different to isokinetic contractions because it is slowest at the start.
This type of training needs special equipment to detect when a muscle is. This annotated bibliography documents three training methods used to develop vertical jumping ability and power: isotonic, isokinetics, and plyometric training. Research findings on all three forms of training are summarized and compared.
A synthesis of conclusions drawn from the annotated writings is presented. The report includes a glossary of terms and an appendix with illustrations of.
While isotonic exercises are not the best way for a person to bulk up, over time it is possible to gain some mass from constant isotonic exercise. Primarily, this sort of exercise is used to maintain a certain level of fitness and muscular definition; but, over long periods of time, you will notice a certain amount of mass building up as well.
Isokinetic exercise allows muscles to gain strength consistently all through the range of movement. With isotonic exercise, the muscle shortens at a.
Correlations among strength measurements were moderate (r= to ). It is concluded that isokinetic, isometric, and isotonic peak force measurements are only moderately correlated to one-leg vertical jump, therefore they cannot be used independently to predict vertical jump ability.

[Les B Troczynski] -- Abstract: The effects of periodized isotonic strength training on subjects (N = 69) utilizing either the power clean exercise (PC), the parallel squat exercise (PS), or no isotonic strength training.
Isotonic exercise definition. The word isotonic comes from two Greek words “iso” means equal and “tonos” means tone. The meaning of Isotonic is maintaining an equal tone of muscle. Isotonic exercise is one type of muscle exercise against weight.
The muscles contract against the load to make the muscles stronger. Benefits of isotonic. The isokinetic group performed three sets of 10 repetitions per set of leg presses each training session. The plyometric group performed three sets of 10 repetitions per set of depth jumps from a height of 34 inches, with added resistance beginning with weeks 3, 5, and 7 of 10, 15, and 20 pounds, respectively.
The concept of isokinetic exercise was developed by James Perrine in the late s. Isokinetics refers to exercise that is performed at a fixed velocity with an accommodating resistance.
Accommodating resistance means that the resistance varies to exactly match the force applied by the athlete at every point in the ROM; thus, the muscle is loaded to its maximum capability at every point. Isometric exercise is also known as static strength training. Examples include the plank and side bridge as well as the wall sit and many yoga poses such as chair and tree poses.
Notice that these are all exercises that involve holding a position rather than moving as is the case with isotonic exercise.
Relative Effects of Isokinetic and Plyometric Training on Vertical Jumping Performance. Blattner, Stuart E.; Noble, Larry Research Quarterly, v50 n4 p Dec A study of isokinetic exercise and isotonic variable-resistance training divided 12 individuals into four groups: 1) control; 2) isotonic variable-resistance training; 3) low-speed isokinetic (5, 10, and 15 rpm); and 4) high-speed isokinetic training (30, 40, and 50 rpm).
All exercised groups showed good gains in strength when tested. The effect of concentric isokinetic strength training of the quadriceps femoris on electromyography and muscle strength in the trained and untrained limb.

Getting the weight moving can be very demanding and can lead to injury or make existing injuries worse. With isokinetic machines there is no such moment of inertia to overcome, which makes these machines safer than traditional forms of strength training.
Isokinetic exercises also produce little in the way of post-exercise muscle soreness. Last week we discussed the importance of aerobic and anaerobic training and this week we will focus on the importance of incorporating strength training into your exercise regimen. Basically, there are several different categories of exercise: Isometric Exercises, Isotonic Exercises and Isokinetic Exercises.
By combining the first two types of exercises during your weekly. Weight training is a common type of strength training for developing the strength and size of skeletal muscles.
It utilizes the force of gravity in the form of weighted bars, dumbbells or weight stacks in order to oppose the force generated by muscle through concentric or eccentric training uses a variety of specialized equipment to target specific muscle groups and types of.
Med Sci Sports. Winter;7(4) Isokinetic vs isotonic strength training in adult men. Pipes TV, Wilmore JH. The differences in changes in strength, body composition, anthropometric measurements and selected motor performance tasks, between groups, trained isotonically and isokinetically were compared.
The word “isotonic” has its roots in the Greek “iso,” meaning equal and “tonos,” meaning tone and describes a type of exercise in which your muscles maintain equal tone or tension while a movement is performed. Isotonic exercises involve two types of contractions: • Concentric, in which a muscle shortens as you overcome the force of a weight.
However, when the individuals were tested for motor performance, the high-speed isoki netic group dominated (% gain in the vertical jump versus % for the slow isokinetic, and % for the isotonic variable resistance; % gain in the standing broadjump versus % and %; and % gain in the yard dash versus % and %).
The tension generated by the dumbbell is now the constant, or in other words if you pick up a 2 kilo dumbbell it weighs 2 kilos whatever you do with elaborate cam systems seen on most modern weight training equipment allow for a more isotonic movement to be performed.
The key to isotonic exercise is that although the weight is constant. System of isokinetic training in which exercises are performed across a range of velocities to deal with the problem of limited physiological overflow of isokinetic training.
Isokinetic testing establish peak torque ratios, examining large muscle group when MMT and HHS (hand held dynamometer) are insensitive, measure muscle fatigue, measure. groups: isokinetic, isotonic, agility, or thought that because of the required intense training, self-motiva- tion was a critical element to the success of the study.
Therefore, group selection was based on patient choice rather than by random the exception of one member of the control group, all subjects were right- leg dominant (dominance. during exercise there is no change in the length of the muscle. Iso means same, metric means length. Although no work is done, near maximum effort is extended.
Isotonic training. Isotonic training is a routine of exercises performed with bar bells, using 15 repetitions as one set. The exercises are designed to develop the legs. By Sarah D.

Isotonic Exercise Benefits. Isotonic exercise is characterized by the production of dynamic external work brought about by muscle contraction.
Essentially, isotonic exercise is the type of exercise that allows your muscles to move against very low resistances for an extended period of time. Examples of isotonic. On ancient ground, opening new horizons. Pioneering deep change in self and society. The participants will be randomly assigned to the isokinetic training group or the isotonic training group.
Outcome measures including isometric peak torque of hip/knee at 90 degree of flexion, peak torque of hip/knee at angular velocity of 60 degree/s and degree/s, Short Form 36 (SF), the Timed Up and Go test, the Oxford Hip/knee Score.In strength tests this should be below (Dvir ) if the test is to be valid.
A high figure is expected in endurance testing. In isometric and isokinetic tests the deviation is worked out from torque whilst in isotonic tests the deviation is from position. Agonist antagonist ratio.
