Biochemical Basis of Sports Performance (Q & A)

Biochemical Basis of Sports Performance (Q & A)


This Pdf introduces the student of sports science or exercise physiology to the biochemical processes that underpin exercise performance and the adaptations that occur with training. The focus is on skeletal muscle metabolism and the provision of energy for working muscles & the principles of exercise biochemistry are introduced in a context that is immediately relevant to the student of sports science. Instead of the traditional approach of working through the main classes of biomolecules and metabolic pathways, the subject is tackled by considering the biochemical processes involved in energy provision for different sports events & the way in which limitations in energy supply can cause fatigue, and thus limit performance.

Biochemical Adaptations in Sport:

1: Metabolism is determined by the:
(a) size of proteins in the cell
(b) availability of amino acids
(c) proteins formed as dictated by the genetic material
(d) protein composition of the DNA
(e) activity of enzymes produced in the nucleus

2: In sprint events, improvements in performance may come from:
(a) faster reaction times
(b) increased power generating ability of muscles
(c) improved resistance to fatigue
(d) all of the above
(e) (a) and (b) only

3: Women’s world record performances have improved rapidly in recent years mainly
(a) women have evolved a greater muscle mass
(b) women can now run faster than men
(c) women have started training at an earlier age
(d) more women are now engaged in sport
(e) the use of ergogenic aids has increased in women

4: Endurance training increases the muscle’s capacity to:
(a) contract faster
(b) breakdown phosphocreatine
(c) burn fat and carbohydrate
(d) generate energy anaerobically
(e) produce more blood cells

5: Which of the following factors does not influence success in sport?
(a) ability to tolerate heavy training without succumbing to illness or injury
(b) tactics
(c) the diet
(d) skill
(e) ingestion of carnitine during exercise
