Ballroom dance is a set of partner dances, which are enjoyed both socially and competitively around the world, mostly because of its performance and entertainment aspects. Ballroom dancing is also widely enjoyed on stage, film, and television.
The foot is an anatomical structure found in many vertebrates. It is the terminal portion of a limb which bears weight and allows locomotion. In many animals with feet, the foot is a separate organ at the terminal part of the leg made up of one or more segments or bones, generally including claws and/or nails.
In some types of partner dance, lead and follow are designations for the two dancers' roles in a dance pairing. The leader is responsible for guiding the couple and initiating transitions to different dance steps and, in improvised dances, for choosing the dance steps to perform. The leader communicates choices to the follower, and directs the follower by means of subtle physical and visual signals, thereby allowing the pair to be smoothly coordinated.
Running is a method of terrestrial locomotion allowing humans and other animals to move rapidly on foot. Running is a type of gait characterized by an aerial phase in which all feet are above the ground. This is in contrast to walking, where one foot is always in contact with the ground, the legs are kept mostly straight and the center of gravity vaults over the stance leg or legs in an inverted pendulum fashion. A feature of a running body from the viewpoint of spring-mass mechanics is that changes in kinetic and potential energy within a stride co-occur, with energy storage accomplished by springy tendons and passive muscle elasticity. The term running can refer to any of a variety of speeds ranging from jogging to sprinting.
The human leg is the entire lower limb of the human body, including the foot, thigh or sometimes even the hip or buttock region. The major bones of the leg are the femur, tibia, and adjacent fibula. The thigh is between the hip and knee, while the calf (rear) and shin (front) are between the knee and foot.

Because ballet became formalized in France, a significant part of ballet terminology is in the French language.
A strike is a directed physical attack with either a part of the human body or with an inanimate object intended to cause blunt trauma or penetrating trauma upon an opponent.
Pointe technique is part of classical ballet involving a technique that concerns pointe work, in which a ballet dancer supports all body weight on the tips of fully extended feet when wearing pointe shoes. A dancer is said to be en pointe when the body is supported in this manner, and a fully extended vertical foot is said to be en pointe when touching the floor, even when not bearing weight.
A gait is a manner of limb movements made during locomotion. Human gaits are the various ways in which humans can move, either naturally or as a result of specialized training. Human gait is defined as bipedal forward propulsion of the center of gravity of the human body, in which there are sinuous movements of different segments of the body with little energy spent. Varied gaits are characterized by differences such as limb movement patterns, overall velocity, forces, kinetic and potential energy cycles, and changes in contact with the ground.
The flutter kick is a kicking movement used in both swimming and calisthenics.
A leglock is a joint lock that is directed at joints of the leg such as the ankle, knee or hip joint. A leglock which is directed at joints in the foot, is sometimes referred to as a foot lock and a lock at the hip as a hip lock. Leglocks are featured, with various levels of restrictions, in combat sports and martial arts such as Sambo, Brazilian Jiu-Jitsu, catch wrestling, mixed martial arts, Shootwrestling and submission wrestling, but are banned in some sports featuring joint locks such as judo. The technique has been seen across a wide range of different combat sports and is reportedly over 2,500 years old, having been seen in the lost art of Pankration in the original Olympic Games.
Footwork refers to dance technique aspects related to feet: foot position and foot action.
Calf raises are a method of exercising the triceps surae, tibialis posterior, and peroneal muscles of the lower leg. The movement performed is plantar flexion, also called ankle extension.
A (bipedal) gait cycle is the time period or sequence of events or movements during locomotion in which one foot contacts the ground to when that same foot again contacts the ground, and involves propulsion of the centre of gravity in the direction of motion. A gait cycle usually involves co-operative movements of both the left and right legs and feet. A single gait cycle is also known as a stride.
A kick is a skill in association football in which a player strikes the ball with their foot. Association football, more commonly referred to as football and also known as soccer, is a sport played world-wide, with up to 265 million people around the world participating on a yearly basis. Kicking is one of the most difficult skills to acquire in football. This skill is also vitally important, as kicking is the way in which passes are made and the primary means by which goals are scored.
The function of the lower limbs during walking is to support the whole-body against gravitational forces while generating movement patterns which progress the body forward. Walking is an activity that is primarily confined to the sagittal plane, which is also described as the plane of progression. During one gait cycle, there are two major phases: stance and swing. In a healthy individual walking at a normal walking speed, stance phase makes up approximately 60% of one gait cycle and swing makes up the remaining 40%. The lower limbs are only in contact with the ground during the stance phase, which is typically subdivided into 5 events: heel contact, foot flat, mid-stance, heel off, and toe off. The majority of stance phase (~40%) takes place in single-limb support where one limb is in contact with the ground and the contralateral limb is in swing phase. During this time interval, the lower limb must support constant changes in alignment of body weight while propelling forward. The hip, knee, and ankle joints move through cyclical kinematic patterns that are controlled by muscles which cross these joints. As postural changes occur, the body adapts by motor tuning an efficient muscular pattern that will accomplish the necessary kinematics required to walk.
