Som vanligt är det enda rätta att helt enkelt vända sig till de vetenskapliga fakta som forskning inom ett ämne i fråga har konstaterat, så även i detta fall.

Så var det avklarat. Tänk så enkelt det hade varit om Angela Saini helt enkelt hade gjort detsamma och vänt sig till forskningen inom ämnet för svar på sin undran.
Men det är klart, det hade väl kanske inte givit henne det önskade beskedet om hon hade gjort detta.

Gender differences in strength and muscle fiber characteristics.
Miller AE1, MacDougall JD, Tarnopolsky MA, Sale DG.
Strength and muscle characteristics were examined in biceps brachii and vastus lateralis of eight men and eight women. Measurements included motor unit number, size and activation and voluntary strength of the elbow flexors and knee extensors. Fiber areas and type were determined from needle biopsies and muscle areas by computerized tomographical scanning.
The women were approximately 52% and 66% as strong as the men in the upper and lower body respectively. The men were also stronger relative to lean body mass. A significant correlation was found between strength and muscle cross-sectional area (CSA; P < or = 0.05). The women had 45, 41, 30 and 25% smaller muscle CSAs for the biceps brachii, total elbow flexors, vastus lateralis and total knee extensors respectively. The men had significantly larger type I fiber areas (4597 vs 3483 microns2) and mean fiber areas (6632 vs 3963 microns2) than the women in biceps brachii and significantly larger type II fiber areas (7700 vs 4040 microns2) and mean fiber areas (7070 vs 4290 microns2) in vastus lateralis.

Muscle mass and strength
Females in general have lower total muscle mass than males, and also having lower muscle mass in comparison to total body mass;[32] males convert more of their caloric intake into muscle and expendable circulating energy reserves, while females tend to convert more into fat deposits.[33] As a consequence, males are generally physically stronger than females. While individual muscle fibers have similar strength between male and female, males have more fibers as a result of their greater total muscle mass.[34] Males remain stronger than females, when adjusting for differences in total body mass, due to the higher male muscle-mass to body-mass ratio.[35] The greater muscle mass is reported to be due to a greater capacity for muscular hypertrophy as a result of higher levels of circulating testosterone in males.[36]
Gross measures of body strength suggest that women are approximately 50-60% as strong as men in the upper body, and 60-70% as strong in the lower body.[37] One study of muscle strength in the elbows and knees—in 45 and older males and females—found the strength of females to range from 42 to 63% of male strength.[38] Another study found men to have significantly higher hand-grip strength than women, even when comparing untrained men with female athletes.[39] Differences in width of arm, thighs and calves also increase during puberty.

Så korkad är jämförelsen.
