The Health Benefits of Table Tennis




The nature of table tennis means that exercising is short and energetic. This allows a varied form of workout resulting in increased heart rate and improvements of overall fitness levels.



Depending on your ability and physical restraints, playing table tennis gives all ages the opportunity to enjoy this form of social exercise while becoming fitter in the process. In some respects it can be seen as offering a total workout, as playing table tennis incorporates numerous body movements ultimately contributing to a thorough fitness regime.



Depending on the aspirations of the player, table tennis appeals to all, as it can be a gentle way to loosen muscles or increase mental awareness while at the professional level it can prove to be an extremely strenuous form of exercise.



In contrast to using other forms of fitness equipment like treadmills and exercise bikes, playing table tennis involves a great deal of mental concentration thus proving popular to fitness enthusiasts who perhaps find other forms of fitness less stimulating.



The benifit of playing table tennis

Play table tennis for exercise , recreation and social outlet . In fact , it trails olny soccer as a participant sport . Little understood and lightly regarded in the united state , table tennis offers several advantages as a life sport that have caused it to be embraced by millions of players worldwide.



Little risk of injury

As a non-contact sport , using a ball that weighs olny a few grams , table tennis is pratically a risk-free sport . Table tennis players do not run the risk of being struck by lightning , breaking bones , banging heads , concussion , or being mistaken for a deer .



Physical benefits

Table tennis , when played competitively , has an impressive list of physical benefits , the most obvious of which is eye-hand coordination .The speed , spin and placement of the ball are crucial and practiced players are expert in both creating and solving puzzles involving these three attributes .



Improved reflexes result because of the fast-paced nature of the sport over very short distances . Both gross and fine muscle movements are improved . The game is distinguished by bursts of exertion and recovery , leading to fast-twitch muscle development . Over the course of play , a fair , yet not extreme , amount of aerobic activity occurs , Players can set their own level of involvement .

Mental benefits

Table tennis is accurately describe as “high-speed chess” . The mental alertness encouraged by the sport’s tactical challenges is particularly good for seniors .

hydration of cement

-Setting time

1. The time taken from additionn of water to initial set and final set
2. Vicast Test-to test cement setting time

Hardening

1. Hardening also means useful strength development

hydration of cement

Hydration=the chemical combination of cement and water

1. Will produce a very had and strong binding medium for aggregate particles in concrete
2. Hydration may continue over a period of a month
3. The heat generated during hydration will affect the durability of concrete due to micro cracking

Learning outcome

-Upon completion of this chapter , you should be able to:

1. Describe hydration of cement
2. discuss factors affecting cement setting
3. Outline the Vicat Test

Concrete

Cement
-Hydration of cement

Moisture

-Saturated , surface dry

1. Ideal state
2. Do not require alteration to mixing water

-Wet

1. Surface moisture is pressent
2. Most common
3. Require deduction of water when mixing

Moisture

-4 states which aggregate may exist in:
-oven-dry

1. on heating to 105 celcius , no loss of weight
2. seldom occur
3. require extra water when mixing

-Air-dry

1. No free moisture and surface are dry
2. Occur at upper part of stockpiles in dry wheather
3. Require extra water when mixing

Strength

-Strength of aggregate generally higher than compressive strength of concrete:
-Factors affecting strength of concrete:

1. Aggregate size
2. Aggregates shape and texture
3. Cleanliness

Sieve Analysis

1. To establish the grading of an aggregate
2. Steps:-

• Air-dried sample passed through series of sieves  of decreasing dimensions
• Use mechanical vibrator/carried out shaking by hand
• Materials retained on each sieve is weighed and recorded
• The % passing through by weight is calculated
• Gradings is determined by comparing to grading requirement (BS 882)

well-graded aggregate

-consist of aggregate with different sizes
-Fill as much as possible of the total space
-Voids between ;arge particles can be filled efficiently with slightly smaller ones.

Grading

-Purpose:to assist in producing concrete with:

1. Satisfactory plastic properties

(workability , cohesion , resist bleeding)

1. Satisfactory hardened properties (strength , durability , surface finish)

Grading

-Particle size distribution of aggregate is called grading
-Coarse aggregate-size bigger than 5mm(3/6 in)
-Fine aggregate -size smaller than 5mm
-Sand-size as low as 0.07 mmm
-Silt -0.06-0.02 mm
-Clay-smaller than 0.02mm

Bulking Test

-To determine% bulking of a damp sand sample
-Steps:

1. Fill in container with damp sand sample (Vd)
2. Add water until saturated .With further addition of water , films of water merge , water moves into voids . This volume is the same as volume of dry sample(V)
3. Calculate %of bulking
