Question

Science of Nurition

1) In a table, please compare between endurance and resistance exercises (list 4 differences at least) (8 points).

2) Please define and explain possible complications of water intoxication and heat exhaustion. (6 points)

Answer 1

Endurance exercise:

1. Endurance exercises includes bicycling, it may involve walking on treadmill, and swimming
2. The phenotype induced by endurance exercise are mitochondrial expansion
3. This is characterized by fatigue resistance due in part to increased oxidative capacity secondary to increased mitochondrial density
4. Aerobic exercises improves functional ability to better extent, it improves muscle endurance

Resistance exerexercis:

1. It involves pumping iron,
2. The phenotypes induced by resistance exercise are myofibrillar protein accretion
3. This results in strengthening muscle fiber cross sectional area
4. It improves muscle strength

2. Definition of water toxication:

When the water is over hydrated with water leads to water intoxication

Definition of heat exhaustion

It is a condition of fatigue and weakness usually with normal body temperature which results from prolonged heat exposure

Complications of water intoxication and heat exhaustion

1. Nausea
2. Vomiting
3. Diarrhoea
4. Fainting
5. Clammy skin
6. Sweating and cold
