Different sports are played all over the world as hobbies, careers or as a part of fitness regimes. Some sports have grown to be more popular than others, attracting billions of fans, so we compiled this list based on participation, TV viewership and rights, prominence in the media, global spread, and salaries at the top level. As the world’s number 1 crowdfunding site for sports, we’ve worked with athletes, teams, and organisations from almost every sport around the world to raise money through sports crowdfunding. The list we’ve compiled are the ten most popular sports in the world today. 10. Volleyball Volleyball is as straightforward as you like. In fact, it is probably the simplicity of the game that makes it so famous among its fans. Take a trip to African countries or visit the beaches of Australia and you will find people playing this sport and you will find people playing this sport. Volleyball is truly one of the most popular sports and has 200 national federations for the sport, more than any other sport on the planet. The most popular sports in Spain 9. Ice HockeyIce Hockey is not only one of the most popular sports in the world but is the most popular winter sport by quite a margin. While the sport has its strongest following in Canada, USA, Russia, Scandinavia and Eastern Europe, there is no doubting its global presence. Most popular sports in India The National Hockey League (NHL) is comprised of clubs from the US and Canada who’s teams are made up of players from around the world. The league itself ranks among the five most popular on the planet as it turns an annual revenue of $4.1 billion. 8. BoxingThe sole representative of combat sports on our list, boxing has fought tooth and nail to mix it with the most popular sports year-on-year. Boxing is a major sport in countries across every single continent and the sheer volume of talent can particularly be seen during the Olympic Games. Most popular sports in America Boxing’s popularity has steadily risen, its growth earmarked by the $400m revenue generated by Mayweather v Pacquiao in 2015 and the record 90,000 sell-out attendance at the Joshua v Klitschko fight at Wembley in 2017. 7. Formula 1With 20 Grand Prix every year in 20 different countries, Formula 1 is one of the most global and most popular sports and has an annual TV audience of over 500 million. The Most Dangerous Sports in the World According to Forbes, the yearly revenue is concerned Formula 1 generate somewhere between $1.5 to $2 billion a year. Which is soundly distributed among 10 f1 teams who in return spend between $100 million to $500 million a season on elite level motor engineers, research & development and of course on driver salaries. 6. RugbyRugby is played in the majority of countries around the world, while it is strongest on in the Southern Hemisphere, in the UK, and in Ireland. As one of the most popular sports in the world, Rugby boasts the second most lucrative and most attended sporting World Cup of all-time with the 2015 Rugby World Cup selling 2.47 million tickets and generating £250m in revenue. In addition, 120 million tuned into the tournament’s final and #rwc2015 was used on average once every two seconds during the tournament’s entirety. The most popular sports to bet on 5. AthleticsTruly one of the most popular sports around the world, athletics represents several disciplines including running, high jump and long jump, as well as other track and field events. The fastest growing sports in the world Athletics has the flagship events of each Olympics and this was proven as the 2012 100-metre final was the most watched single Olympic event in the Games’ history with over 1 billion television viewers tuning in from across the globe. 4. TennisWith an average of 45 countries represented in top 100 tennis ranking in both the men’s and women’s game, tennis is without question among the world’s most popular sports. Furthermore, players from both the men’s and women’s game, from 30 different countries, have won at least one grand slam, making it a unique record in sport. The most popular horse riding sports Over 1 billion people tuned in at some point during Wimbledon 2014, 2015 and 2016, while an average of over 17 million tunes into the UK-only BBC One channel for the tournament’s men’s final. 3. Cricket
With an estimated 2 billion followers, cricket is one of the most popular sports in the world. The Twenty20 league is the third most-viewed sporting event behind the FIFA World Cup and Rugby World Cup. The 5 biggest annual sporting events Women’s cricket is growing rapidly, which shows the spread of the sport’s support worldwide. The ICC (International Cricket Council) has increased television coverage and prize money for women’s competitions and female players are now paid 50% more than they did 5 years ago. 2. BasketballWith over 1 billion fans, the second-highest number of professional leagues worldwide, and the highest average salary at the top level ($4.4m), basketball is the world’s fastest growing sport. Basketball is the fastest growing sport on every scale from revenue, to competitions/leagues. More and more professional leagues are being established in countries across the world, especially in eastern European countries like Poland, Hungary, Czech Republic, Serbia, and Lithuania. The world’s fastest sports Couple this growth with basketball’s already-established pro leagues in the US, Greece, Spain, Turkey, Italy, China, Argentina, and France and it’s not hard to see why Basketball ranks highly on the list of most popular sports. 1. SoccerWith over 4 billion fans worldwide, soccer is the clear No.1 choice on our most popular sports list. Football is one of the most accessible sport in the world and there is hardly anyone in this world who has not kick a ball at some point in their life. The 10 greatest athletes of all time Soccer has the highest viewership (3.9 billion tuned into the 2014 World Cup at some point), the highest prize money (€1.5 billion awarded in prizes and bonuses in the Champions League), the most expensive TV right (Sky paid £5.3 billion in 2016 to air the Premier League), as well as the biggest kit deals and richest clubs with 30 of the top 50 richest sports teams coming in the form of soccer clubs.

Toussaint Received 2009 Dec 7; Accepted 2010 Mar 2. Copyright © Journal of Sports Science and Medicine Sex is a major factor influencing best performances and world records. Here the evolution of the difference between men and women’s best performances is characterized through the analysis of 82 quantifiable events since the beginning of the Olympic era. For each event in swimming, athletics, track cycling, weightlifting and speed skating the gender gap is fitted to compare male and female records. It is also studied through the best performance of the top 10 performers in each gender for swimming and athletics. A stabilization of the gender gap in world records is observed after 1983, at a mean difference of 10.0% ± 2.94 between men and women for all events. The gender gap ranges from 5.5% (800-m freestyle, swimming) to 18.8% (long jump). The mean gap is 10.7% for running performances, 17.5% for jumps, 8.9% for swimming races, 7.0% for speed skating and 8.7% in cycling. The top ten performers’ analysis reveals a similar gender gap trend with a stabilization in 1982 at 11.7%, despite the large growth in participation of women from eastern and western countries, that coincided with later- published evidence of state-institutionalized or individual doping. These results suggest that women will not run, jump, swim or ride as fast as men. Key points
Key words: World records, best performances, gender difference, elite sport Sex has been identified as a major determinant of athletic performance through the impact of height, weight, body fat, muscle mass, aerobic capacity or anaerobic threshold as a result of genetic and hormonal differences (Cureton et al., 1986; Maldonado-Martin et al., 2004; Perez-Gomez et al., 2008; Sparling and Cureton, 1983). Some authors have suggested that gender differences in race records may disappear (Beneke et al., 2005; Tatem et al., 2004; Whipp and Ward, 1992); other have studied physiological limits in sport with non linear models, but with limited data (Nevill and White, 2005; Nevill et al., 2007). However, men and women differences should first be studied through the complete panel of quantifiable Olympic disciplines. Over the modern Olympic era (1896-2007) the evolution of time, distance or height values of world records was shown to follow a piecewise exponential model (Berthelot et al., 2008). Further, women presently display lower record values compared to men. An asymptote for all events has been suggested, with a limit in women’s performances that remains inferior to men’s. Thus, gender gaps will probably be settled when men and women reach their physiological limits. Here we compare the improvement of male and female world records and ten best performances (ie. the best performance of the top ten performers of each gender every year) over the modern Olympic era in order to measure the evolution of gender gaps. The data set included 82 events from five quantifiable Olympic disciplines (International Olympic Committee, 2008; Official Fina website, 2008; USA Swimming website, 2008): athletics, swimming, speed skating, track cycling and weightlifting. The number of each Olympic event by discipline is given in Table 1. Only events strictly comparable between men and women were studied. For track events, selected races have the same distances for both (women’s 100m hurdles and men’s 110m hurdles have been excluded) and of field events, only jumps were included. Throws were excluded as projectile weights are different for men and women. All weight categories in weightlifting do not exactly match (8 divisions for men from 56kg to 105+kg and 7 for women from 48kg to 75+kg). Therefore weightlifting world records analysis was performed through 3 classes only: the heaviest (Heavyweight), the lightest (Flyweight), and an in-between matching category (Lightweight, 63-69kg for women and 64-70kg for men). Comparable events between male and women. Only events strictly comparable are included in the study (100m Hurdles Women, 110m Hurdles Men and throws excluded).
For all 82 Olympic events, world records progressions were compiled. Each gender gap series started with the first common chronological record for both men and women. An unbeaten record was extended until it is improved (there is not one newly established record every year); 2768 gaps were measured for world records (Figure 1). For 60 swimming and athletics events, the best performance of the first ten performers were collected every year from three data sources (International Olympic Committee, 2008; Official Fina website, 2008; USA Swimming website, 2008) over the 1891 - 2008 period for 26 athletics events and the 1963 - 2008 period for 34 swimming events; 23864 performances were analysed (ie. 11932 ten best performances gaps) from a compiled International Olympic Committee database collecting 45968 best performances (International Olympic Committee, 2008) with associated gender and citizenship. The gender gaps between world records (WR) and between ten best performances were calculated, as well as their scattering evolution and number of records beaten yearly. For each year, the gap between the two records is calculated as follows:
The gaps of the top ten performers were measured each year. Ten gaps were calculated; the first female performance compared to the first male performance, the second female to the second male and so forth. The yearly ten best performances gender gap TBPi is the mean of the 10 individual gaps:
A breaking slope method was used for the gender gap (GG) curves of 66 Olympic events in swimming, athletics, speed skating and track cycling. It aimed to find the best combination of two linear regressions, which showed the largest difference between their slope - a significant decrease in gender gaps variations. For each event, a first model was performed with a minimum of eight points (eights years of records or performances) to fit the first linear regression. The second regression was fitted with the points that were left (from the ninth point to the last one). An eight year segment representing two Olympiads was chosen as the minimum time span over which a period could be considered as stable. Then, a second model was created with the first slope now including one more point, and the second slope including the points left. All possible two part linear models were thus performed until all points were included in the first slope. For each model, coefficients of each slope, differences of slopes and global R2 of each regression are collected. Finally, the model with the greatest R² and the most significant slope difference was kept. The breakpoint date was then determined by the cross point of the two linear regressions of the chosen model. Gender gaps evolution according to time was modelled by
Stated otherwise, the trends before and after the breakpoint date τ are linear, but the slope of the two lines may differ on either side of the breakpoint. Regression parameters α, β, α' and β' were estimated by maximum likelihood; the R2 coefficient measured the global fit of the model to the data. Analyses were conducted using SAS software 9.2 version (SAS Institute, Cary, NC, USA) After the breakpoint dates, the stabilized gender gaps ∆m were calculated and expressed as follows: with j being the date of stabilization. The standard deviation of the ten best was measured for each event in order to calculate the yearly coefficient of variation cv(t): with representing the mean value of the 10 performances vector at year t and σp(t): standard deviation of the performances vector. The coefficients of variation of the gender gaps for the two periods (before and after breakpoint date) were compared by a Wilcoxon signed-rank test. This non-parametric test was used since the data (performances values) could not be assumed to be normally distributed. The annual cumulative proportions were used to describe the secular evolution of world records (Guillaume et al., 2009). Factor ac,t is the annual ratio of the number of world records for the country c over the total number of world records: P is the annual cumulative proportion over the Olympic era: for the first year t0, year t and the country c. Factor P defines the annual cumulative world records progression rate for each country. For the evolution analysis of factor P, the mean slope of annual cumulative proportions (S) was calculated by linear regressions over 4 periods: 1921-1940, 1951-1970, 1971-1990, 1991-2008. S was defined as: Statistical analysis was performed with the R software (R Development Core Team, 2008). One way linear regressions were used to calculate the slopes of factors G and P. Statistical significance was considered at p < 0.01. In two disciplines (athletics and swimming), a graphic representation of the number of world records obtained each year through a 4-year smoothing mean illustrated the gender profile of their evolution since the beginning of the Olympic era. The breaking slopes method shows a breakpoint date separating the events into two periods. The first one fits the fast reduction of the gender gaps, while the second one corresponds to a period of stability (after 1978, Figure 1C). Results of the Wilcoxon test show that the two periods are significantly different, with the coefficients of variation of the second period being inferior to the first one. Slope breaks results are listed in Table 2. Breakpoint dates; GG at stability; and Variation coefficient before breakpoint date (CV BD) and after (CV AD) for all events. * If a breakpoint date is not detectable (recently officialised women event), the given value is the last 2008 GG.
Analysis of world records in athletics shows that global stability was reached in 1983.7 (± 9.57). Gender gaps have been stable in jumping and running events since 1982.3 and 1984.8 respectively. Gender gaps decreased in the running events from 30.0% (± 6.48) in 1922 to 10.7% (± 1.85) since their stabilisation, and from 30.1% (± 8.52) to 17.5% (± 1.11) for jumping events. For the ten best performances, the global stability date is 1983.9 (± 4.45). The ten best performances’ gender gaps evolved from 25.3% (± 4.46) for races at the beginning of the Olympic era to 11.2% (± 1. 25) since stabilization and from 30.0% (± 3.86) to 19.0% (± 2.57) after 1984 for jumps. Gender gaps have been stable since 1979. 9 in swimming events. In swimming, world records gender gaps evolved from 22.9 % (± 5.44) at the beginning of the century (1916) to 8.9 % (± 1.54) since their stabilization. For the ten best performances, results show stability in 1981.5 at 10.16 % (± 1.60) while it was 13.4% (± 1.86) in 1963. Only one event was comparable in cycling. The gender gap in the sprint has been stable since 1993 at 8.7%. In speed skating the gender gap no longer fluctuates since 1989.7 (± 2.1) at 6.95% (± 0.16). The gender gap in weight lifting world records is at 36.8% (± 6.2) since women officially started competing in 1998. With 10 years of hindsight only, no breakpoint date has been detected yet. World records evolution (Figure 2) was altered by both world wars, with a decreasing number of records during these two periods. A similar trend is also observed at the beginning of the 1980s for swimming and of the 1990s for athletics. A major peak in swimming for both male and female appears around 1970, while such peaks occur at different dates in athletics: 1960 for men and 1983 for women. Since the beginning of the Olympic era, the United States of America has dominated men’s athletics and men and women’s swimming (Figure 3). The German Democratic Republic (GDR) was the first European country to dominate women’s athletics and swimming, starting after the Second World War.

For the USA, the largest slope corresponds to the period from 1950 to 1970, except for women’s athletics (1970-1989). In athletics, the men’s slope is greater (0.007) than the women’s (0.002). The GDR’s greatest slope corresponds to the period from 1970 to 1989 and is more important for the women (0.009 for swimming and 0.007 for athletics) than for the men (0.004 and 0.0015, respectively). The greatest slopes observed in the Chinese performances occur after 1990. Slope of linear regressions of annual cumulative proportions of WR for the major 6 countries.
Our results show that the gender gap in Olympic sport performance has been stable since 1983. These suggest that women’s performances at the high level will never match those of men. This stabilization is the expression of a significant narrowing of gaps for all events (Cheuvront et al., 2005). Indeed, even when performances still improve, these progressions are proportional for each gender. The reduction and stabilization of the gender gaps in performance is a general pattern observed in all athletes and all disciplines (Figure 4). Stability appears through all of the parameters studied: coefficients of variation, slope coefficients, coincident breakpoint dates between world records and ten best performances. This stability is not affected by external, non physiological factors such as technology and doping advancements that could challenge it. The yearly analysis of the number of world records shows a major, 22-year time lag in athletics between the men’s and women’s peaks, corresponding to the period where the fastest reduction in the gender gap occurred. After 1950, women began to benefit from improvements in training techniques that were developed from the men’s training experience during the first half of the XXth century. Like men, they also benefited from a better medical and nutritional environment. The fast improvement rate of female performances' observed since then could also be explained by the increasing number of events proposed to women and by the investment of East European nations in women’s sports (Geipel, 2001; Seppelt and Schück, 1999). In fact, the last period of acceleration in these improvements prior to the breakpoint date of the early 1980s coincides with published evidence of institutionalized doping. According to former GDR athletes, many of them were being administrated drugs to enhance muscle strength, aggressiveness and performance since 1966 (Franke and Beredonk, 1997; Geipel, 2001). However the trend linking performance-enhancing drugs and women in particular is still unknown. While it should be considered that the technological advancements leading to increased efficiency of some androgenic drugs on the physiology of female athletes could have played a role in some countries' investment in women’s sport programs, the inverse could also be true. It may have been the idea of a potential progression margin in female sport as analyzed just after the Second World War, associated with the discovery of ergogenic and androgenic steroids that could have induced the interest and investment in the development of doping techniques to be applied to female athletes. Women doping during the 1970s could have sped up female progression and accelerated the gender gap reduction. During the Cold War, many countries were fighting for the largest political influence. One manner in which to obtain international prestige was realized through athletic performance (Guillaume et al., 2009). While women’s sports were not as developed as men’s, east European countries, such as GDR, invested in female performance programs (Staatsplan 14.25) (Franke and Beredonk, 1997; Seppelt and Schück, 1999). With the use of androgenic steroids, beating records and winning medals were probably seen as an easier challenge for women than men. Such a strategy of optimized returns may have translated into an early and intense investment of communist countries in women’s sport (Geipel, 2001; Seppelt and Schück, 1999), later followed by other countries or individuals (Guillaume et al., 2009). In fact, the geographical repartition analysis of world records evolution (Figure 5) shows a wider distribution of nations for women’s athletics than for men’s, with a women’s domination by Russia after the Second World War, while men’s competitions show a larger dominance by USA athletes. Unlike athletics, a time lag is not observed in swimming, where women’s competitions chronologically started much earlier. While men’s first records were obtained in 1927 on average for all swimming races, women’s world records were first set in 1932. Only 5 years separate the beginning of swimming competitions for each gender while 28 years separated the first men records (1914 on average for all events) from first women records (1942) in athletics. In women’s weightlifting, we did not detect a breaking point due to the recent introduction of women into this sport. Performances and gender gap have nevertheless both reached a plateau. Besides, 50.4% of world records in women weightlifting are set by Chinese athletes (Guillaume et al., 2009). A recent and slight increase in gender gaps can be observed for 12 out of 38 events. This is not specific to any particular discipline, and corresponds to the enhancement of men’s performances with a simultaneous regression or stabilization of women results. Also a small discrepancy is shown between the predicted year where women and men will reach world records asymptotic limits (2028 vs 2042 respectively) (Berthelot et al., 2008). Taking into consideration that men may continue to progress in a few events, gender gaps may slightly increase before reaching full stability (Seiler et al., 2007; Holden, 2004). Random and unannounced drug testing was introduced in athletics in 1989. The declining use of banned performance-enhancing drugs may have also contributed to the most recent and slight increase of gender gaps. Men still improve, though at a lower rhythm, while women stopped their progression. Men are more likely to adopt behaviours at increased risk, whereas a higher percentage of women engage in preventive actions linked to health and longevity (Courtenay, 2000; Mercer et al., 2007). Another explanation could be the higher interest of media in male sport, and the greater rewards offered. This major investment of East European countries in women’s sport can be assessed by the annual cumulative proportions slope coefficient. Soviet Union has a slope twice as high as the USA’s for women’s world records during the 1970s and the 1980s. East Germany’s progression slopes are always greater for women than for men and similar to the Russian women’s progression for athletics. The percentage of women’s world records obtained by GDR athletes is about 33.1% between 1970 and 1989 and 30.7% for the Soviet Union, compared to 11.2% for the United States of America and 3.2% for West Germany. This massive representation of two countries (Riordan, 1996; Seppelt and Schück, 1999), in which the incidence of doping was proven or highly suspected, could have accelerated the reduction of the gender gaps (Franke and Beredonk, 1997; Geipel, 2001). However, it should be clear that these are not the only nations in which female athletes have resorted to illegal performance enhancing procedures. The connection between women’s participation in international events and performance may not be quite relevant. On average, the mean date of the first men’s world records was 1925 (± 21), while mean date for women first world record was 1955 (± 36). Despite a 30 year time lag average between men and women mean debuts, women rapidly progressed before the gender gaps stabilized. The number of participants in the Olympic Games is a measurable indicator of the involvement of elite athletes globally. Quotas and incentives of organizing authorities encourage the participation of women. While only 37 women attended the 1908 Olympic Games, in 2008 they represented 42.4% of all registered athletes (4746 women and 6450 men) at the Olympic Games in Beijing (International Olympic Committee, 2008). The number of competing women is still increasing while the number of men has reached a maximum at the 1988 Olympic Games in Seoul (Figure 4). After taking into account the evolution of world records previously studied in this analysis, there is no measurable effect of the increasing number of women participating in the Olympic Games on world records, ten best performances and gender gaps evolution. The major increase in women’s participation takes place in the 1980s, while the world record peak already occurred (Berthelot et al., 2008), and the gender gaps stability period has begun. A breakpoint date could not be detected in 3 events: pole vault (a female event not contested from 1930s to the 1960s), 5000m and 10000m due to their recent introduction into the Olympic program. Women’s weight lifting world records only began in 1998, when most of men’s world records had already reached their maximal values. This explains why gender gaps are still narrowing in this discipline (though at a slower pace in the last few years). The wide discrepancy between the magnitude of gender gaps in weightlifting and jumping events and the four other disciplines studied here could be explained by the different physiological mechanisms involved to mobilize energy. The predominantly explosive type of effort required in weightlifting and jumping (Maldonado-Martin, 2004; Wilmore and Costill, 2004) could explain the greater disadvantage that women have to face against men, compared to other disciplines. It appears that gender gaps in sport performance have been stable for a long time: women may never catch up with men. This stabilization of 26 years is the expression of a significant drop in the variation of these gaps' magnitude. After a significant narrowing of gender gaps, women and men now evolve in parallel, in the same direction. The late implication of women in competition, their increasing participation, as well as the individual doping behaviours and state programs for performance enhancement may all have had a historical role but no longer reduce the gap. Without any technological improvement specifically dedicated to one gender or the other, performances will probably evolve in a similar manner for both men and women. The gap may be set.
