Positive Health Benefits of Improved Grip strength

INTRODUCTION

To gain the maximum strength for your fist and arm, you don’t need to hit the gym anymore, hand grippers will do the service for you. Hand grippers are portable devices that operate in various ways of squeezing, grabbing, or bolting to improve the strength of your hand and forearm muscles.

 Strength of fingers, fist, and arm are the foundation of some professions ranging from guitarist to some tool manufacturer or a writer, and along with these, throwing power is inevitable for some sports as well e.g. weightlifting, martial arts, and golf, etc.

Beneficial medical effects of improved grip strength:

Generally, 3 types of grips are focused for improvement, by hand-grippers including crush grip, pinch grip, and support grip which are utilized during handshaking, holding objects between fingers and thumb and holding something for some time respectively. 

A study, published in 2012 on “reference value for handgrip strength on young people of both sexes” found mean reference value of female handgrip strength to be 27.70 ± 4.3 kg and for male, it was 44.77 ± 6.6 kg, all the subjects belonged to 19–25 years age group. [1]

Now let’s take a look at beneficial effects of ameliorated strength of your handgrip on your overall health:

  1. 1 . Improved lung capacity:

Improvement in lung functioning is related to aerobic exercises designed for this purpose yet a study conducted in 2016, found no correlation between physical activity and improved lung capacity in healthy subjects. Later on, they correlated muscle strength with lung capacity focused on handgrip as a representative of overall muscle strength and found positive results.

The study “Handgrip strength is associated with improved spirometry in adolescents” was conducted involving 1846 subjects, males included belonged to a mid and late-pubertal group, while females belonged to late and post-pubertal age group. The average handgrip strength for boys was 35.4kg and 26.6kg for girls.

Average lungs volume (FEV1) and capacity (FVC) were 3.84L, 4.51L for boys and 3.21L, and 3.65L for girls respectively [3]. Each additional kg of grip strength in boys was associated with 29ml increased FEV1 and 28ml increased FVC values. For girls, the increase was 21ml (FEV1) and 20ml (FVC) for an additional 1kg of improved grip strength. There was an increased peak expiratory flow (PEF) rate observed as well for each kg increase in grip strength by the values of 59ml/sec among boys and 53ml/sec among girls [2].

2 . Cope with Aging hands:

With advancing age, there is reduced muscle mass and functioning of hands. Biochemical changes, lack of physical activity, reduced exercise, sedentary lifestyle lead to disuse atrophy of hand muscles affecting grip strength as well. The pattern of loosening of grip strength depends upon many factors including nutritional status, genetics, gender, and underlying bone diseases.

A retrospective cross-sectional study “Age-related decline in handgrip strength differs according to gender” was conducted on 1787 men (mean age 53, range 18-91 years) and 861 women (mean age 52, range 18-88 years). It stated that handgrip strength deteriorates with increasing age, and it was faster in men after 30 years and after 50 years in women [3].

A study “Aging hands” published in the journal of Gerontology stated reduction of muscle mass in old-age ranging from 25% to 45%. It stated a decline in grip strength, due to decreased vascularity of tendons, pathological changes in bones and joints as well as a decrease in muscle mass, of 20-25% [4]. Another study claimed to revert the aging-related hand changes by progressive strength training [5].   

3 . Reduces premature mortality:

Muscle weakness, chronic diseases, and less body weight are usually seen in some people, handgrip strength is considered a representative of overall muscle strength. Meanwhile, poor muscular strength has seen to be associated with both increased morbidity as well as mortality in diverse samples of people ranging from middle-aged to elderly [6].

A 5-year prospective cohort study “Handgrip strength and mortality in older Mexican Americans” conducted on 2488 Mexican aged 65 and above, found average handgrip strength ± standard deviation in men to be 28.4 kg ± 9.5 and 18.2 kg ± 6.5 in women. A follow up after 5 years revealed 507 deceased, the men who had handgrip strength less than 22.01kg (38.2%), and the women who had handgrip strength less than 14kg (41.5%) respectively [7].

Another study “Handgrip strength and mortality in the oldest old population” included 555 subjects among which 444 died in a period of average 9.5-year follow-up, the mortality rate was pretty high among those who exhibited the lowest tertile of handgrip strength. Moreover, significantly raised mortality was observed in those with the highest relative loss of hand-grip strength over 4 years [6].

4 . Reduces old-age disability:

The arm and hand muscle’s performance, handgrip strength may be used to predict functional limitations, grade, and risk of disability in apparently healthy individuals. The decline of muscular strength which is often associated with aging can be a step towards functional disability.

A study “Hand-grip strength predicts incident disability in non-disabled older men” found that among 422 survivors from subjects, 58 had a disability in performing daily life activities (ADLs), and instrumentals daily life activities (IADLs), 179 had in mobility, IADLs or both and 185 were not disabled. In this sample, the severity of disability was cross-sectionally linked with handgrip strength [8].

Another study “Midlife handgrip as a predictor of disability” reported 3218 of its living and followed up participants among the total of 6089 men, 2.2% had difficulty in rising from the chair without using their arms, 6.2% had complaint of walking very slowly, yet there was clear cut link between these reported disabilities and baseline handgrip strength tertiles [9].

So, the strength of handgrip is an indicator for many red flags, you may have to deal with, on your road to aging.

4 . Benefits among hypertension patients:

Hypertension is a prevalent condition, a modifiable risk factor for various cardiovascular diseases adding a significant role in morbidity and mortality stats related to CVS diseases. It is found to be more prevalent in the elderly, it was recorded to 68% prevalent in Brazil inhabitants in a study conducted there [5]

 A study “Grip strength as a marker of Hypertension and Diabetes in healthy weight individuals” found mean hand-grip strength lowered among undiagnosed hypertensive patients as compared to healthy individuals (63.5 vs 71.5kg). It also compared the mean handgrip strength of already diagnosed hypertensive with normal healthy individuals (60.8 vs 71.5kg) [10].

Another study “sustained effects of resistance training on blood pressure and handgrip strength following a detraining period in elderly hypertensive women” conducted on fifteen participants with an evaluation done of 9 women in total found systolic and diastolic BP to be reduced than it was pre-training, during detraining, DBP stayed 13% lower than it was during pre-training [5].

After 14 weeks of resistance training, hand-grip strength was significantly increased and it did not decline during and after detraining, instead it stayed 6% more than it was pre-training [5].

Features and respective benefits in our Hand gripper:

Our hand gripper is designed to engage all the intrinsic and extrinsic muscles of the hand, most muscles of the forearm, and all possible joints of your arm as well. It is designed for to and fro motion of gripping member against resistance to make sure movement in all possible angles.

Let’s take a look at unique features of this hand-gripper along with benefits it is offering:

Knob/gripping member:

The knob is the main rotating object in this whole apparatus which rotates around a threaded shaft towards the cycler on the opposite end. The hand rotating the knob will be actively using most of the muscles, tendons, and joints for desired results.

Knob comes in 3 different shapes that are responsible for involving different muscle groups specifically and almost all other structures generally.

  • Star-shaped knob, utilizing grasp by fingers and thumb and subsequent rotation as well. It will strengthen the flexors muscles and tendons of your fingers. Overall rotation will involve wrist joint, forearm muscle’s strength as well. 
  • The round knob will fit between your thenar prominence, other palm muscles, and your fingers. Fingers and your wrist will co-ordinate to make rotatory movement around the shaft. 
  • Engraved cylindrical knob, fits perfectly well in your palm. Rotation of the wrist is needed to make the knob dragged towards the opposite end. 

Cylinder:

When fully assembled, you would need to hold the cylinder tightly to avoid its rotation along with the movement of the gripping member around the threaded shaft that passes through the cylinder. The hand holding it will be indirectly adding the resistance to the other hand’s rotation around the shaft. Movement of the hand holding involves gripping by palm muscles and extension and flexion at a rib joint, due to constant for a strong grip.  

Threaded shaft:

Extends from knob to the cylinder on the other end, with rotatory, to and fro motion of knob on it, it forward or backward as well due to a hole located at the end of the cylinder.

The movement generated by the collective involvement of knob and shaft involves palmar muscles, muscles at the dorsum of hand and forearm muscles along with simultaneous flexion and extension at the wrist joint.

Two-way resistance:

While rotating the knob towards the cylindrical cap, there is constantly increasing resistance, due to compression of internally installed spring which recoils back and applies pressure on the opposite side when you start rotating knobs towards the opposite end.

These opposing resistances require action from the same muscles yet in opposite direction.

FDA approved similar devices:

There are other hand-grippers available in the market as well, which serve the same purpose of improvement in handgrip, hand muscles, and mobility of various joints there. Let’s take a look at their features and how they differ from the hand-gripper we are presenting to you:

1 . Zona Plus: 

Zona plus is an FDA approved, portable, software-controlled device, which is designed for hand-grip therapy and allows its user to link with his unique physiology by measuring handgrip strength beforehand.

It has a grabbing handle with compressible sides that are pushed against its user’s palm and finger muscles’ resulting in improved hand-grip and its 4-8 week use has reported benefits on lowering of systolic and diastolic blood pressures [12].

2. Hand wrist rehabilitation training finger orthotics:

Hand wrist rehabilitation training orthotics is unique and one of its kind, FDA approved apparatus. It features leather covering to be tied around the wrist, and highly compressed strings attached to a metallic stand that is attached over the wrist area.

Clutches attached to fingers exert strong force against the resistance offered by springs, thus improving the strength of the finger’s muscles while keeping the wrist steady. Against such high resistance, not only the finger’s muscle strength is improved but also of palm muscles whose tendons are inserted on phalanges.  

3 . Pro hand exerciser:

Pro hand exerciser is popular among professional athletes, famous musicians are also used as a rehabilitation tool. It features four knobs for fingers to press them and attain endurance against the resistance it provides. It is designed to be held between thenar, hypothenar muscles on one side, and fingertips on the other side, along with individual strength for fingers it also strengthens the grip of palm.  

Conclusion:

Taking into account all the positive arguments in the favor of increased hand-grip strength and how it is a reliable indicator of a subject’s nutritional status, a predictor of morbidity and mortality indices among sample groups.

We threw light on the benefits of handgrip strength improvement in various diseases as well, after all this discussion, it is found to be a more important aspect of overall body fitness than it is portrayed to be and need to be emphasized more upon.

 Hand grippers are perfect for the job of improving strength as well as reducing the age-related effects on associated joints. Make sure to choose the hand-gripper that engages maximum muscles and joints simultaneously for better results.
