Explain the Role That Heredity Plays in Skill Related Fitness

Skill-related components of physical fitness like speed, agility, balance, coordination, power, and reaction time rely heavily on technique and practice to improve. But there is also an underlying genetic component that determines your baseline abilities and potential in these areas. While dedicated training helps optimize skill related fitness, heredity plays in skill related fitness significant role by shaping your muscle fibers, coordination, body proportions and natural abilities.

Heredity Impacts Muscle Fiber Composition

Muscle fiber types are a key area where genetics influence physical performance potential:

Higher Percentage of Fast-Twitch Fibers Linked to Genetics

Human muscles contain a blend of slow-twitch and fast-twitch muscle fibers in ratios that are primarily determined by heredity. Those with a naturally higher proportion of fast-twitch fibers have inherent advantages in power and explosiveness.

Fast-Twitch Fibers Contribute to Power and Speed

Fast-twitch muscle fibers generate faster, more explosive contractions. These quick force abilities lend themselves to skills like sprinting, jumping, and quick multi-directional movements.

Fast and Slow-Twitch Ratios Vary

The percentage of fast vs. slow-twist fibers can vary dramatically between individuals based on genetic inheritance. Elite sprinters often have 70-80% fast-twitch fibers.

Difficult to Convert Fiber Types Through Training

While you can increase muscle size through training, the actual ratio of fast to slow-twitch fiber types within your muscles remains largely immutable.

The specific fiber type ratio you inherit plays a major role in determining your innate power, speed, and agility capabilities that contribute to overall skill related fitness.

Family History Indicates Coordination and Reaction Time

In addition to muscle fibers, genetics seem to influence more neurological elements like coordination:

Studies Show Correlations in Coordination Among Family Members

Recent studies tracking coordination abilities through bloodlines show measurable correlations between family members. This points to hereditary factors influencing coordination.

Reaction Time Also Has Genetic Link

Like coordination, reaction time also demonstrates patterns between biologically related individuals. Quick reactions to stimuli appear influenced by genetics.

Motor Learning Differs Between Individuals

Research on motor learning for new skills demonstrates high variability between subjects in capability to improve coordination through practice based on inherent abilities.

Baseline Reflexes Vary

Simple reflex tests like primary reflexes show a wide normal range innate from birth. Genetic components seem to dictate baseline quickness.

Your inherent coordination skills and reaction time upon which skill related fitness depends may be largely predetermined through hereditary factors.

Height and Limb Length Determine Mechanical Advantage

Body structure and proportions are additional areas where genetics provide skill related advantages:

Genetics Determine Stature and Limb Length

Height and the lengths of limbs, torsos and digit ratios are almost entirely inherited genetically, not developed through training.

Longer Limbs Can Enable Greater Speed

The right biomechanics like long legs and short torsos allow greater stride length and joint extension which enhance running speed.

Lever Lengths Dictate Strength and Power

Longer limbs provide better mechanical leverage for generating jumping and throwing power as well as strength and skill related fitness.

Body Segment Ratios Impact Potential

The ratios of leg length to torso size, arm span to torso length and other body segment relationships are optimized in certain skill athletes.

In many skill-related sports, specific body proportions and limb lengths provide performance advantages based on simple biomechanical leverage and range of motion advantages.

Body Type Can Influence Balance and Agility

An individual’s somatotype or body build can also impart benefits or challenges when developing balance and agility:

Lower Center of Gravity Aids Balance  

A stocky mesomorph build places someone’s center of gravity lower, enhancing innate balance capability.

Posture and Flexibility Factor In

Postural alignment and joint/muscle flexibility inherited through genetics also aid or inhibit balance and body control.

Mesomorphs Excel in Agility

Mesomorphs with greater muscle mass and fast twitch muscles have physical advantages in terms of foot speed and agility potential.

Ectomorphs Face Challenges

Ectomorphs naturally excel in endurance activities but have a tougher time developing strength, power and quickness for agility.

Your inherited body type shapes your physical skills and attributes, making certain skill related fitness elements easier or more challenging.

Genetics Determine Skill Potential in Athletics and Fitness

While skill related fitness components absolutely can be improved through deliberate training, genetics set the upper bound for possible achievement. Your hereditary traits shape the inherent physical and neurological attributes that dictate your aptitude and potential across athletic domains demanding speed, power, agility and coordination.

Heredity and Muscle Performance

Muscle fiber typing and mechanical advantages derived from limb length and body type are key performance differentiators shaped by genetics:

Fast-Twitch Muscles for Power Sports

Sports like sprinting, jumps, throws, and hockey rely heavily on explosive fast-twitch power. The highest potential in these sports goes to those with genetically gifted fast twitch ratios over 70%.

Slow-Twitch Advantages in Endurance

Conversely, endurance sports favor those genetically predisposed with very high percentages of slow-twitch muscle fibers for sustained activity like marathons and cycling.

Lever Lengths and Strength Potential

The longest, most mechanically advantaged levers and limbs will generate greater torque and leverage for punching, throwing, and jumping power.

Body Types Prone to Injury

Ectomorphs with slight builds must be cautious of the wear and tear certain sports like football can inflict due to their genetic frameworks.

Your genes provide the template dictating your highest physical capabilities. Training then allows you to optimize within your genetic parameters.

Heredity’s Influence on Neurological Skills

Quick reactions and precise coordination also have strong genetic links:

Family History Correlates With Reflexes

Studies showing correlations in reaction times between twins and family members suggest reflexes and quick reactions are highly hereditary.

Kinesthetic Sense Varies at Birth

An innate “proprioceptive” sense or awareness of body position develops prenatally. The sensitivity of this kinesthetic sense differs genetically.

Visual Processing Speed Depends on Genes

The ability to perceive, orient and react to visual cues with speed is enhanced in those born with faster cognitive visual processing those easily accepting skill related fitness.

Motor Learning Aptitude Differs

Some athletes innately pick up new complex coordination skill related fitness with ease based on genetic predisposition while others struggle due to a lack of inherent motor learning ability.

The neurology and circuitry you are born with predetermines quickness and coordination proficiency required in high level sports.

Implications for Training and Development

Knowing your genetic tendencies should guide skill development:

Tailor Training to Genetic Strengths

Train according to your innate abilities a sprinter shouldn’t force marathon training against natural power and speed strengths.

Mitigate Genetic Weaknesses

However, certain training can help compensate for deficiencies like improving mobility and quickness for bigger athletes.

Avoid Discouragement

Understand lack of elite skill related fitness mastery despite extensive practice may simply indicate hereditary limitations rather than poor work ethic or coaching.

Test for Best Sport Fit

Trying a variety of sports and tracking skill progression can help reveal which activities your genetic attributes best align with.

While we can’t change our genetics, understanding and training within their possibilities and limitations allows us to maximize skill-related fitness potential.

Conclusion

While consistent training and practice develops skill related fitness abilities, the baseline potential you have is strongly influenced by heredity. The ratio of fast to slow-twitch muscle fibers you are born with establishes innate quickness and power capabilities. Coordination skills, reaction times, body proportions, posture and natural abilities demonstrate measurable correlations between family members and across body types. So while nearly anyone can improve balance, agility, speed and power through dedicated training, your genetics provide the foundation upon which your efforts can build. Understand and embrace your unique hereditary strengths and weaknesses to optimize skill development.
