Handgrip strength is important for any sport in which the hands are used for catching‚ throwing or lifting. Also‚ as a general rule people with strong hands tend to be strong elsewhere‚ so this test is often used as a general test of strength.

the strengthening of metal alloys. It influences some properties of the alloys such as strength‚ hardness and ductility. The purpose of this experiment was to test the effect of temperature and aging time on strength and hardness of 6060 aluminium alloy samples that have roughly similar compositions by subjecting them to different temperatures for different periods of time. The experiment showed that the strength and hardness of the samples increased when they were allowed to age for longer time under

and manageability. Statement of the Problem: Specifically‚ the researchers aimed to answer the following questions: 1. Can gugo and okra be used as raw material in making shampoo? 2. How effective are gugo and okra on the tensile strength of the hair? 3. Which treatment is more effective – treatments with greater concentration of okra than gugo or more gugo than okra? Procedure A. Preparation of Materials About 10‚000 hair strands were gathered from four respondents having

DEVELOPMENT OF MAXIMUM SPRINTING SPEED By Frank W. Dick‚ BAAB Director of Coaching‚ Great Britain The 15th Annual Congress of the European Athletics Coaches Association (held in East Germany last January) focused on sprints and hurdles. We are fortunate to have this contribution firom EACA president and British director of coaching Frank Dick. Dick analyzes the Seoul 100m results and points out the important differences in sprint technique and training between men and women. REPRINTED FROM TRACK

Young’s Modulus: This is the slope of the linear portion of the stress-strain curve‚ it is usually specific to each material; a constant‚ known value. Yield Strength: This is the value of stress at the yield point‚ calculated by plotting young’s modulus at a specified percent of offset (usually offset = 0.2%). Ultimate Tensile Strength: This is the highest value of stress on the stress-strain curve. Percent Elongation: This is the change in gauge length divided by the original gauge length

is useful in injury rehabilitation‚ thus returning people to pain-free activity. Weight training increases power‚ speed‚ muscular endurance‚ and flexibility for many types of activities. Strength vs. Endurance The two aspects of muscle development to consider are strength and endurance. Muscular strength refers to “power” or amount of force that is exerted by a muscle group against a resistance. Muscular endurance is the ability of a muscle group to perform an activity against resistance over

Certainly passive tension isn’t as effective as active tension in packing on lean mass. Many believe that the continuous quest for increased maximal strength is the key to developing massive muscles. But while increased strength is definitely related to increased muscle cross sectional area (CSA)‚ there are multiple adaptations that can boost strength without increasing muscle hypertrophy (Schoenfeld‚ 2010). In Neuromechanics of Human Movement‚ Roger Enoka (Enoka‚ 2008) lists

The aim of this experiment is to perform tensile tests on samples of standard steel‚ aluminium alloy and copper in order to calculate Young’s Modulus. In addition to this‚ also yield stress‚ tensile strength and percentage elongation and reduction of area will be calculated‚ only for the standard steel sample.

The hundreds of exercises performed in the weight room help strengthen every muscle in the body. The sport of Bodybuilding trains the athlete to gain size and definition. This sport requires long‚ hard hours of weight training where the workouts concentrate on heavy weight and small reps for size and strength. Weight workouts help build
