Несомненно, связь варикоза и тяжелого физического труда есть, однако речь идет о подъеме тяжестей (регулярном). При этом нагрузки - провоцирующий фактор.
Факторы риска оцениваются в популяционных исследованиях. К сожалению, отечественных работ на эту тему не нашел. В исследовании RELIEF (с Российским участием), оценивалась ХВН - не совсем по нашей теме. Вот что дал "скрининг" по Медлайну:

The epidemiology of varicose veins. A survey in western Jerusalem.Abramson JH, Hopp C, Epstein LM.Цитата:
In both sexes, significant associations were found with standing at work and with region of birth. Among women, varicose veins were associated with weight, the wearing of corsets, and having ever been pregnant. Among men, there was an association with inguinal hernia. The findings support the aetiological role of prolonged standing and raised intra-abdominal pressure.

Epidemiology of varicose veins.
Callam MJ.
Department of Surgery, Bedford General Hospital, U.K.Цитата:
The data suggest that female sex, increased age, pregnancy, geographical site and race are risk factors for varicose veins; there is no hard evidence that family history or occupation are factors. Obesity does not appear to carry any excess risk.
Нет убедительных доказательств, что семейный анамнез и профессия являются факторами риска варикозной болезни.
В «подразделе» довольно известного Эдинбергского исследования (Edinburgh Vein Study) авторы пишут со ссылкой на этот же обзор от Callam:
Цитата:
The evidence to support any association between varices and many lifestyle factors such as prolonged standing, tight undergarments, toilet posture, chair sitting, and dietary fibre intake is lacking.
Нет связи с длительным стоянием.

Work conditions as risk factors for varicose veins of the lower extremities in certain professions of the working population of Rijeka.
Kontosić I, Vukelić M, Drescik I, Mesaros-Kanjski E, Materljan E, Jonjić A.Очень любопытный абстракт этого популяционного исследования:
Цитата:
This research aims to establish the effect of working conditions on the appearance of varicose veins. The epidemiological study was carried out on 1,324 examinees, 530 males and 794 females, employed in 5 highly represented groups of professional activities in Rijeka (catering, trade, light industry, heavy industry and finances). The data were collected by survey and clinical examination. Varicose veins were more prevalent in the trade than in the office workers (odds ratio (OR) = 2.08; 95% confidence interval (CI) = 1.31-3.31), and more prevalent in catering industries than in the office workers (OR = 1.56; 95% CI = 1.001-2.43). chi 2-testing suggested that standing in the workplace (OR = 1.35; 95% CI = 0.95-1.92), weight handling while working (OR = 1.29; 95% CI = 1.01-1.64) and working indoors (OR = 1.61; 95% CI = 1.02-2.53) were risk factors for varicose veins. By multiple logistic regression, the following risk factors were isolated in the total population: female sex (OR = 1.92; 95% CI = 1.37-2.67), workplace (OR = 0.89; 95% CI = 0.78-0.99), age (OR = 1.05; 95% CI = 1.03-1.07), body mass index (OR = 1.04; 95% CI = 1.01-1.07) and family history of the disease (OR = 1.99; 95% CI = 1.55-2.57).
Итак, стояние – фактор риска.

The epidemiology of chronic venous insufficiency and varicose veins.

Department of Epidemiology, School of Public Health, Division of Venous Disease University of Michigan, Ann Arbor, Michigan 48109, USA.Цитата:
Established risk factors include older age, female gender, pregnancy, family history of venous disease, obesity, and occupations associated with orthostasis. Yet, there are several factors that are not well documented, such as diet, physical activity and exogenous hormone use, which may be important in the development of chronic venous disease and its clinical manifestations.
Профессия, связанная с ортостатическими нагрузками, и семейный анамнез причислены к установленным факторам риска.
Итак, ортостатические нагрузки и профессии, с ними связанные - скорее являются фактором риска развития варикозной болезни. А вот на счет подъема тяжестей - данных нет...
